Substitute Part Grouping Explanation

Substitute parts for the RMCF2010FT90R9 are qualified based on strict equivalence across the following parameters:

• Resistance value: 90.9 Ohms
• Tolerance: ±1%
• Power rating: 0.75W
• Package: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

All substitute parts listed meet these criteria and are electrically and mechanically interchangeable with the primary part number.

Parameter Comparison

Engineering Selection Recommendations

CRCW201090R9FKEF (Vishay Dale) is the primary recommended substitute for new designs and ongoing production. This part maintains active product status and carries full AEC-Q200 automotive qualification with ROHS3 compliance. Inventory availability is 4108 pieces.

ERJ-12SF90R9U (Panasonic Electronic Components) is electrically and mechanically equivalent but carries a "Not For New Designs" status. This part is suitable for legacy system support, field replacements, or applications where existing qualification documentation references this manufacturer. Inventory availability is 15498 pieces.

Selection between substitute parts should prioritize active product status for new designs while considering manufacturer qualification history and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can CRCW201090R9FKEF be used as a direct replacement for RMCF2010FT90R9?

A: Yes. Both parts are identical in resistance (90.9 Ohms), tolerance (±1%), power rating (0.75W), package (2010), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and AEC-Q200 automotive qualification. No circuit redesign or board layout modification is required.

Q: What is the difference between the substitute parts?

A: CRCW201090R9FKEF and ERJ-12SF90R9U are electrically and mechanically identical. The primary difference is product status: CRCW201090R9FKEF is active for new designs, while ERJ-12SF90R9U is designated "Not For New Designs" by Panasonic.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed parts, including the primary RMCF2010FT90R9, are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can these parts be used in automotive applications?

A: Yes. All parts carry AEC-Q200 automotive qualification and operate across the required temperature range of -55°C to 155°C, meeting automotive reliability standards.

Q: What is the physical package size?

A: All parts use the 2010 (5025 Metric) package with dimensions of 0.197" L x 0.098" W (5.00mm x 2.50mm) and maximum seated height of 0.028" (0.70mm).
