Substitute Part Grouping Explanation

Substitute parts for the RMCF2010FT5K90 are qualified based on strict equivalence across the following critical parameters:

• Resistance value: 5.9 kOhms
• Tolerance: ±1%
• Power rating: 0.75W
• Package: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

All identified substitutes meet these parameters identically. Substitution is valid when all electrical characteristics, package dimensions, and compliance certifications match the main part specification.

Parameter Comparison

Engineering Selection Recommendations

CRCW20105K90FKEF (Vishay Dale) is the primary substitute for RMCF2010FT5K90. Both parts are active in production with full AEC-Q200 automotive qualification and ROHS3 compliance. Vishay Dale maintains higher inventory availability (12,628 units) compared to Stackpole (910 units), supporting supply chain resilience.

ERJ-12SF5901U (Panasonic Electronic Components) is electrically and mechanically equivalent but carries a "Not For New Designs" product status. This part remains suitable for legacy system maintenance and repair applications where existing designs require component replacement. New design implementations should prioritize CRCW20105K90FKEF or RMCF2010FT5K90 to ensure long-term production support.

Frequently Asked Questions (FAQ)

Q: Can CRCW20105K90FKEF replace RMCF2010FT5K90 in automotive applications?

A: Yes. Both parts are AEC-Q200 qualified with identical electrical specifications (5.9 kOhms ±1%, 0.75W), temperature performance (±100ppm/°C, -55°C to 155°C), and package dimensions (2010/5025 Metric). Direct substitution is valid for automotive designs.

Q: Why is ERJ-12SF5901U marked "Not For New Designs"?

A: ERJ-12SF5901U maintains full electrical and mechanical equivalence but is in end-of-life status. Panasonic designates this part as unsuitable for new product development to encourage migration to active alternatives. Existing applications may continue using this part for maintenance and repair.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RMCF2010FT5K90, CRCW20105K90FKEF, and ERJ-12SF5901U are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What determines substitution validity for this resistor category?

A: Substitution requires matching resistance value (5.9 kOhms), tolerance (±1%), power rating (0.75W), package (2010), composition (thick film), temperature coefficient (±100ppm/°C), operating range (-55°C to 155°C), and AEC-Q200 automotive qualification. All listed substitutes meet these criteria.

Q: Can I use ERJ-12SF5901U in new designs?

A: No. Panasonic's "Not For New Designs" status indicates this part is not recommended for new product development. Use CRCW20105K90FKEF or RMCF2010FT5K90 for new designs to ensure production continuity and long-term support.
