Substitute Part Grouping Explanation

Substitute parts for the CRCW04022R55FNED are qualified based on the following criteria:

Electrical Parameters: Resistance value (2.55 Ohms), tolerance (±1%), and power rating (0.063W) must be identical across all substitutes.

Mechanical Parameters: Package type (0402/1005 Metric), physical dimensions (0.039" L x 0.020" W, 1.00mm x 0.50mm), and termination count (2) must match exactly.

Environmental & Compliance: All substitutes must maintain AEC-Q200 automotive qualification, ROHS3 compliance, MSL 1 rating, and the specified operating temperature range (-55°C ~ 155°C).

Allowed Variation: Temperature coefficient may vary (±100ppm/°C to ±200ppm/°C) as this parameter does not affect primary electrical function within the specified operating range for this resistance value and tolerance class.

Two substitute parts meet these criteria: CRCW04022R55FKED (Vishay Dale, upgrade variant) and RMCF0402FT2R55 (Stackpole Electronics Inc, direct equivalent).

Engineering Selection Recommendations

CRCW04022R55FKED (Vishay Dale): This part is an upgrade variant within the same manufacturer series. It maintains identical electrical and mechanical specifications to the CRCW04022R55FNED with the exception of a lower temperature coefficient (±100ppm/°C versus ±200ppm/°C). Both parts carry active product status, full AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating. This substitute is suitable for direct replacement with higher inventory availability (4370 units in stock).

RMCF0402FT2R55 (Stackpole Electronics Inc): This part provides cross-manufacturer equivalence with identical electrical specifications and mechanical compatibility. It maintains the same 2.55 Ohm resistance, ±1% tolerance, 0.063W power rating, and 0402 package dimensions. The part carries active product status, AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating. Temperature coefficient matches the original part (±200ppm/°C). This substitute is suitable for applications requiring multi-source qualification or when Vishay Dale parts are unavailable.

Frequently Asked Questions (FAQ)

Q: Can CRCW04022R55FKED be used as a direct replacement for CRCW04022R55FNED?

A: Yes. Both parts are manufactured by Vishay Dale with identical resistance (2.55 Ohms), tolerance (±1%), power rating (0.063W), package (0402), and automotive qualification (AEC-Q200). The temperature coefficient difference (±100ppm/°C versus ±200ppm/°C) does not affect functional compatibility for this resistance value and tolerance class.

Q: Is RMCF0402FT2R55 compatible with the original CRCW04022R55FNED?

A: Yes. RMCF0402FT2R55 is manufactured by Stackpole Electronics Inc and provides full electrical and mechanical equivalence. Resistance, tolerance, power rating, package type, dimensions, and automotive qualification are identical. Both parts operate across the same temperature range (-55°C ~ 155°C) with matching temperature coefficients (±200ppm/°C).

Q: Are all three parts suitable for automotive applications?

A: Yes. CRCW04022R55FNED, CRCW04022R55FKED, and RMCF0402FT2R55 all carry AEC-Q200 automotive qualification and are rated for the operating temperature range of -55°C to 155°C.

Q: What is the significance of the temperature coefficient difference between CRCW04022R55FNED and CRCW04022R55FKED?

A: CRCW04022R55FNED has a temperature coefficient of ±200ppm/°C while CRCW04022R55FKED has ±100ppm/°C. For a 2.55 Ohm resistor with ±1% tolerance across the -55°C to 155°C operating range, this difference does not create functional incompatibility. Selection between these variants depends on application-specific stability requirements.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. CRCW04022R55FNED, CRCW04022R55FKED, and RMCF0402FT2R55 are all supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.

Q: Do all parts meet RoHS and REACH compliance requirements?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is MSL 1 (Unlimited) for all parts.
