Frequently Asked Questions (FAQ)

Q: Can CRCW040256K0FKED be used as a direct replacement for CRCW040256K0FKEE?

A: Yes. Both parts are manufactured by Vishay Dale with identical electrical and mechanical specifications, including 56 kOhm resistance, ±1% tolerance, 0.063W power rating, 0402 package, AEC-Q200 automotive rating, and ROHS3 compliance. The difference in part number suffix (FKEE vs. FKED) reflects packaging or tape configuration variations that do not affect circuit functionality.

Q: Is RMCF0402FT56K0 from Stackpole Electronics compatible with the Vishay Dale CRCW040256K0FKEE?

A: Yes. RMCF0402FT56K0 meets all critical electrical and mechanical parameters: 56 kOhm resistance, ±1% tolerance, 0.063W power rating, 0402 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, AEC-Q200 automotive qualification, and ROHS3 compliance. Cross-manufacturer substitution is valid for this application.

Q: Are there any package or footprint differences between these substitute parts?

A: No. All three parts use the 0402 (1005 Metric) package with identical dimensions: 0.039" L × 0.020" W (1.00mm × 0.50mm) and maximum seated height of 0.016" (0.40mm). PCB footprints and assembly processes remain unchanged.

Q: Do all substitute parts maintain AEC-Q200 automotive qualification?

A: Yes. CRCW040256K0FKEE, CRCW040256K0FKED, and RMCF0402FT56K0 are all AEC-Q200 qualified, meeting automotive reliability and quality standards. Operating temperature range of -55°C to 155°C is consistent across all parts.
