Substitute Part Grouping Explanation
Substitution eligibility is determined by strict equivalence across the following parameters:
- Resistance value: 3.6 kOhms
- Tolerance: ±1%
- Power rating: 0.1W (1/10W)
- Package: 0603 (1608 Metric)
- Composition: Thick Film
- Temperature coefficient: ±100ppm/°C
- Operating temperature range: -55°C ~ 155°C
- RoHS compliance: ROHS3 Compliant
- Moisture sensitivity: MSL 1
All substitute parts listed meet these electrical and mechanical specifications. Differences in physical dimensions (length, width, height) within tolerance and packaging format (tape & reel vs. cut tape) do not affect functional equivalence.

Engineering Selection Recommendations
For applications requiring AEC-Q200 automotive qualification, select from CRCW06033K60FKEA (Vishay Dale), ERJ-3EKF3601V (Panasonic Electronic Components), or AC0603FR-073K6L (YAGEO). These parts maintain full automotive compliance equivalent to the original MCR03EZPFX3601.
For non-automotive applications where AEC-Q200 certification is not required, CR0603-FX-3601ELF (Bourns Inc.) and RC0603FR-073K6L (YAGEO) are functionally equivalent alternatives with active product status and higher inventory availability.
MCR03ERTF3601 (Rohm Semiconductor) is a direct manufacturer variant of the original part but is also discontinued. This option is suitable only if existing supply chain relationships with Rohm Semiconductor are preferred.
All listed substitutes are ROHS3 compliant with MSL 1 rating, matching the environmental and regulatory requirements of the original part.
Frequently Asked Questions (FAQ)
Q: Can I use these substitute parts interchangeably with MCR03EZPFX3601?
A: Yes, all listed parts are electrically and mechanically equivalent. They share identical resistance (3.6 kΩ), tolerance (±1%), power rating (0.1W), package (0603), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). Physical dimension variations are within acceptable tolerances for 0603 package specifications.
Q: What is the difference between parts with and without AEC-Q200 certification?
A: AEC-Q200 certification indicates automotive-grade qualification. Parts with this rating (CRCW06033K60FKEA, ERJ-3EKF3601V, AC0603FR-073K6L) meet automotive reliability and testing standards. Parts without this rating (CR0603-FX-3601ELF, RC0603FR-073K6L) are suitable for general industrial and consumer applications but should not be used in automotive designs requiring compliance.
Q: Does packaging format (tape & reel vs. cut tape) affect compatibility?
A: No. Packaging format affects only handling and assembly logistics, not electrical or mechanical performance. Both tape & reel and cut tape formats are compatible for the same circuit application.
Q: Why is MCR03EZPFX3601 discontinued?
A: The original part is discontinued at DiGi Electronics. However, functionally equivalent alternatives from multiple manufacturers remain in active production with substantial inventory availability.
Q: Which substitute has the highest inventory availability?
A: RC0603FR-073K6L (YAGEO) has the highest inventory at 131,509 pieces. ERJ-3EKF3601V (Panasonic) follows with 92,119 pieces, and CRCW06033K60FKEA (Vishay Dale) with 84,986 pieces.
