MCR10EZHUFX7501 Übersicht
A chip resistor (also called an SMD resistor or surface-mount resistor) is a passive electronic component that provides a precisely controlled resistance in a small, reflow-solderable package. Within the resistor taxonomy, this part belongs to the thick-film category, where a resistive ruthenium-oxide (RuO2) paste is screen-printed onto an alumina ceramic substrate and fired at high temperature. Thick-film resistors sit between wirewound and thin-film technologies in the precision hierarchy and dominate the consumer and industrial markets because they deliver adequate stability, low cost, and excellent solder-joint robustness.
Key specifications of the MCR10EZHUFX7501 include a 7.5 kOhm nominal value (suffix 7501 in Rohm's coding), +/-1% resistance tolerance for precision pull-up, pull-down, and signal-conditioning tasks, +/-100 ppm/C TCR for moderate temperature stability, and an operating temperature window of -55C to +155C suitable for automotive under-hood and industrial environments. The 0805 footprint (2.0 x 1.25 mm) provides a balance between power handling and PCB density.
Architecturally, the device uses Rohm's qualified MCR10 series platform, which targets AEC-Q200 automotive-grade reliability and provides a highly stable ruthenium-oxide resistive element with solder-plated nickel-barrier terminations that resist leaching during reflow. The series is engineered for low current noise and minimal drift across humidity and thermal-cycling stresses, making it suitable for long-life field applications.
Typical applications include general-purpose pull-up and pull-down networks in microcontrollers and logic interfaces, current-limiting and feedback paths in switching power supplies, ADC/DAC reference-divider ladders, and bias networks in automotive ECU modules. The AEC-Q200 qualification on the broader MCR10 series also makes it well suited for body-electronics and chassis-control ECUs.
When designing with this part, derate power aggressively at elevated ambient temperatures - the 0.125 W rating assumes 70C or below. Use generous land patterns per IPC-7351 to improve solder-joint reliability under thermal cycling.

Typische Anwendungen
MCR10EZHUFX7501 ist geeignet für 6 Anwendungs: Automotive ECU Pull-up / Pull-down Networks, Switching Power Supply Feedback Divider, ADC / DAC Reference Divider Ladder, Industrial Control Board Bias Networks, LED Current-Limiting Resistor (Low-Power Indicator), General-Purpose Surface-Mount Replacement Stock.
Automotive ECU Pull-up / Pull-down Networks
The MCR10EZHUFX7501 fits automotive ECU general-purpose pull-up and pull-down networks because its 7.5 kOhm value is a standard biasing resistance for CMOS logic thresholds, while the 0.125 W rating is conservative for digital-signal currents under a few mA. The MCR10 series carries AEC-Q200 qualification, making it suitable for body-electronics, chassis-control, and infotainment ECUs. With +/-1% tolerance and +/-100 ppm/C TCR, it delivers repeatable logic thresholds across -40C to +125C automotive temperature ranges. Placed between the MCU GPIO and the supply/ground rail, it sets deterministic idle levels on sensor and communication lines.
Empfohlen
Switching Power Supply Feedback Divider
The MCR10EZHUFX7501 is well-suited to switching power supply feedback divider networks where a 7.5 kOhm resistor pairs with a lower-value resistor to set the converter output voltage. Its +/-1% tolerance keeps the regulated output within tight limits across production, and the 0.125 W power rating easily handles the sub-mA divider currents typical of low-power DC-DC converters. The 0805 footprint enables compact PCB layouts adjacent to the controller IC, while the +/-100 ppm/C TCR contributes only modest reference drift across operating temperature.
Empfohlen
ADC / DAC Reference Divider Ladder
The MCR10EZHUFX7501 fits ADC and DAC reference-divider ladders that need precision resistance matching to scale a stable voltage reference to the converter's full-scale input range. Its 7.5 kOhm value integrates cleanly with common 2.5 V or 4.096 V references, while the +/-1% tolerance keeps gain error below the LSB of a 12-bit converter. The MCR10 series thick-film technology is stable across humidity and thermal cycling, and the 0805 package sits close to the reference pin to minimize leakage and pick-up. Designers seeking higher precision can substitute thin-film parts such as the ERA-6AEB752V from Panasonic.
Empfohlen
Industrial Control Board Bias Networks
The MCR10EZHUFX7501 is a good fit for industrial control board bias networks that set operating points on op-amp inputs, transistor bases, and gate-drive interfaces. Its 7.5 kOhm value provides a moderate-impedance bias that rejects noise while drawing negligible quiescent current, and its 0.125 W power rating handles continuous bias dissipation with ample margin. The -55C to +155C operating temperature range covers factory-floor enclosures and outdoor cabinet environments. Because the part is now obsolete, designers of new industrial products should select the actively-produced Vishay CRCW08057K50FKEA or Yageo RC0805FR-077K5L drop-in alternatives for long-term supply continuity.

LED Current-Limiting Resistor (Low-Power Indicator)
The MCR10EZHUFX7501 can serve as a current-limiting resistor for low-power indicator LEDs in human-machine interface (HMI) panels, where the 7.5 kOhm value provides a few hundred microamps of drive current at typical 3.3 V or 5 V logic rails. Its +/-1% tolerance ensures consistent LED brightness across production, while the 0805 footprint is small enough for dense front-panel layouts. The thick-film ruthenium-oxide construction tolerates the small steady-state dissipation without drift. For high-brightness LEDs requiring more current, a lower-value resistor from the same MCR10 series is recommended.

General-Purpose Surface-Mount Replacement Stock
The MCR10EZHUFX7501 is a convenient general-purpose surface-mount replacement stock item for repair shops and contract manufacturers who maintain a wide range of EOL resistors. The 7.5 kOhm value is a frequently-used bias, termination, and divider value, and the 0805 footprint matches the most common hand-soldering and rework land pattern. With a tolerance of +/-1% and a power rating of 0.125 W, it covers most analog-signal and digital-bias repair scenarios. Because the part is obsolete, repair depots should pair it with an active alternative such as the Yageo RC0805FR-077K5L to bridge stockout periods.

Wichtigste Unterscheidungsmerkmale
- Obsolete status limits long-term availability (vs. RC0805FR-077K5L)
- Tighter tolerance vs Panasonic ERJ-6GEYJ752V (vs. ERJ-6GEYJ752V)
- Rohm MCR10 series ecosystem for legacy compatibility (vs. CRCW08057K50FKEA)
Designhinweise
The 0.125 W power rating of MCR10EZHUFX7501 is specified at 70C ambient. Above 70C, derate linearly to zero at +155C; in practice, halve the rating for any design that operates continuously above 85C ambient. Voltage stress should also be limited to sqrt(P x R) to avoid hot-spot failure; for 7.5 kOhm at 0.125 W the limiting voltage is about 31 V, comfortably above typical 3.3 V or 5 V rails.
Use the standard IPC-7351 0805 land pattern with pad dimensions of approximately 1.20 mm x 1.10 mm and pad pitch of 1.20 mm. Keep the resistor away from high-voltage or high-current traces to minimize leakage and thermal coupling. For automotive AEC-Q200 designs, follow the manufacturer-recommended solder paste stencil and reflow profile (typically SnAgCu, peak < 260C for less than 10 seconds).
Do not assume the part is in production: the MCR10EZHUFX7501 is listed as obsolete at multiple distributors and the broader MCR10EZHFS series has been announced for EOL by Rohm. For new designs, substitute the Yageo RC0805FR-077K5L or Vishay CRCW08057K50FKEA, both AEC-Q200 qualified and in active production. Also verify that the 1% tolerance and 100 ppm/C TCR meet your circuit accuracy requirements; high-precision analog designs should consider thin-film alternatives such as Panasonic ERA-6AEB752V (0.1%, 25 ppm/C).
