Substitute Part Grouping Explanation
Substitution eligibility for the MCR03EZPFX9313 is determined by strict equivalence across the following parameters:
- Resistance value: 931 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 to 155°C (exact match required)
All substitute parts listed below meet these electrical and mechanical specifications. Variations in packaging format (Cut Tape vs. Tape & Reel) and minor dimensional tolerances do not affect functional equivalence.

Engineering Selection Recommendations
For applications requiring AEC-Q200 automotive qualification, select from CRCW0603931KFKEA (Vishay Dale), ERJ-3EKF9313V (Panasonic), or RMCF0603FT931K (Stackpole Electronics). All three parts maintain active product status with robust inventory availability and full automotive compliance.
MCR03ERTF9313 (Rohm Semiconductor) provides a direct manufacturer alternative but lacks AEC-Q200 certification and is discontinued. RC0603FR-07931KL (YAGEO) is active and widely available but does not carry AEC-Q200 rating; this part is suitable for non-automotive applications requiring moisture-resistant thick film composition.
For new designs and production requiring automotive-grade components, CRCW0603931KFKEA offers the highest inventory level (44,938 pcs) and active product status.
Frequently Asked Questions (FAQ)
Q: Can I substitute MCR03EZPFX9313 with any of the listed parts?
A: Direct substitution is possible only with parts matching all electrical parameters: 931 kOhms resistance, ±1% tolerance, 0.1W power rating, 0603 package, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. All listed parts meet these criteria.
Q: What is the difference between AEC-Q200 and non-AEC-Q200 parts?
A: AEC-Q200 certification indicates the part meets automotive industry reliability and qualification standards. For automotive applications, use CRCW0603931KFKEA, ERJ-3EKF9313V, or RMCF0603FT931K. Non-certified parts (MCR03ERTF9313, RC0603FR-07931KL) are suitable for industrial and consumer applications only.
Q: Does packaging format (Cut Tape vs. Tape & Reel) affect electrical performance?
A: No. Packaging format affects only handling, storage, and assembly logistics. Electrical and thermal characteristics remain identical regardless of packaging format.
Q: Why is MCR03EZPFX9313 discontinued?
A: Product discontinuation is a manufacturer decision unrelated to component performance. Equivalent active alternatives are available from multiple manufacturers with identical electrical specifications.
Q: Which substitute offers the best inventory availability?
A: CRCW0603931KFKEA (Vishay Dale) provides the highest inventory level at 44,938 pieces with active product status and full AEC-Q200 compliance.
Q: Are all substitutes ROHS3 compliant?
A: Yes. All listed substitute parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the original MCR03EZPFX9313 specifications.
