MCR03EZPFX9761 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX9761 is a 9.76 kOhms ±1% 0.1W chip resistor in 0603 (1608 Metric) package manufactured by Rohm Semiconductor. This automotive-grade thick film resistor meets AEC-Q200 qualification standards and operates across -55°C to 155°C. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active product lines that maintain identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters:

Resistance value: 9.76 kOhms (exact match required)
Tolerance: ±1% (exact match required)
Power rating: 0.1W / 1/10W (exact match required)
Package: 0603 (1608 Metric) (exact match required)
Composition: Thick Film (exact match required)
Temperature coefficient: ±100ppm/°C (exact match required)
Operating temperature range: -55°C ~ 155°C (exact match required)
RoHS compliance: ROHS3 Compliant (exact match required)
Moisture sensitivity: MSL 1 (exact match required)

All substitute parts listed below meet these criteria. Variations in physical dimensions (length, width, height) within standard tolerances and differences in packaging format (Cut Tape vs. Tape & Reel) do not affect functional equivalence.

Engineering Selection Recommendations

For applications requiring automotive AEC-Q200 qualification, select from: CRCW06039K76FKEA (Vishay Dale), ERJ-3EKF9761V (Panasonic), or RMCF0603FT9K76 (Stackpole Electronics Inc). All three are active products with AEC-Q200 certification matching the original MCR03EZPFX9761 specification.

For non-automotive applications where AEC-Q200 is not required, CR0603-FX-9761ELF (Bourns Inc.) and RC0603FR-079L (YAGEO) provide equivalent electrical performance with moisture-resistant thick film construction and superior inventory availability.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical electrical parameters. Selection should prioritize active product status and supply chain availability for long-term production requirements.

Frequently Asked Questions (FAQ)

Q: Can MCR03EZPFX9761 be directly replaced with any of these substitutes?

A: Yes. All listed parts are direct functional equivalents meeting identical electrical specifications (9.76 kΩ ±1%, 0.1W, 0603 package, ±100ppm/°C, -55°C to 155°C operating range). Physical dimensions vary within standard tolerances but do not affect PCB assembly compatibility.

Q: What is the difference between AEC-Q200 and non-AEC-Q200 variants?

A: AEC-Q200 certification indicates automotive-grade qualification. CRCW06039K76FKEA, ERJ-3EKF9761V, and RMCF0603FT9K76 carry this certification. CR0603-FX-9761ELF and RC0603FR-079K76L do not. Use AEC-Q200 parts for automotive applications; either variant is acceptable for industrial or consumer applications.

Q: Does packaging format (Cut Tape vs. Tape & Reel) affect electrical performance?

A: No. Packaging format affects only logistics and handling. Electrical and mechanical specifications remain identical regardless of packaging type.

Q: Which substitute offers the best supply availability?

A: RC0603FR-079K76L (YAGEO) has the highest inventory at 375,736 pieces, followed by RMCF0603FT9K76 (Stackpole) at 271,494 pieces.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed parts are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level).
