Substitute Part Grouping Explanation

Substitution eligibility for the CRCW04022R40FNED is determined by strict equivalence across the following critical parameters: resistance value (2.4 Ohms), tolerance (±1%), power rating (0.063W / 1/16W), package type (0402 / 1005 Metric), composition (thick film), operating temperature range (-55°C ~ 155°C), automotive qualification (AEC-Q200), and compliance certifications (ROHS3, REACH Unaffected). All identified substitute parts meet these requirements. Temperature coefficient variations (±100ppm/°C vs ±200ppm/°C) and minor dimensional differences (height seated maximum) do not disqualify substitution when all primary electrical and mechanical parameters align.

Engineering Selection Recommendations

All substitute parts listed maintain full electrical and mechanical compatibility with the CRCW04022R40FNED. Selection among these alternatives should be based on supply availability, lead time, and inventory levels. The CRCW04022R40FKED (Vishay Dale) offers an improved temperature coefficient specification (±100ppm/°C) compared to the original part (±200ppm/°C), providing enhanced stability in temperature-sensitive applications while maintaining identical resistance, tolerance, power rating, and package specifications. The RMCF0402FT2R40 (Stackpole Electronics Inc) and AC0402FR-072R4L (YAGEO) are direct functional equivalents with standard temperature coefficient performance. All parts carry AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 moisture sensitivity rating, confirming suitability for automotive and industrial applications across the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can CRCW04022R40FKED be used as a direct replacement for CRCW04022R40FNED?

A: Yes. Both parts share identical resistance (2.4 Ohms), tolerance (±1%), power rating (0.063W), package (0402), composition (thick film), operating temperature range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. The CRCW04022R40FKED features an improved temperature coefficient (±100ppm/°C vs ±200ppm/°C), making it suitable for applications requiring tighter temperature stability.

Q: Are RMCF0402FT2R40 and AC0402FR-072R4L compatible with the original CRCW04022R40FNED?

A: Yes. Both parts meet all critical electrical and mechanical parameters: 2.4 Ohms ±1%, 0.063W power rating, 0402 package, thick film composition, -55°C ~ 155°C operating range, and AEC-Q200 qualification. These are cross-manufacturer equivalents suitable for direct substitution.

Q: What is the significance of the temperature coefficient difference between ±100ppm/°C and ±200ppm/°C?

A: Temperature coefficient indicates resistance change per degree Celsius. A tighter specification (±100ppm/°C) provides better resistance stability across temperature variations. For most general-purpose applications, both specifications are acceptable. Applications requiring precise resistance maintenance across wide temperature ranges may benefit from the ±100ppm/°C specification.

Q: Do all substitute parts have the same package dimensions?

A: All parts use the 0402 (1005 Metric) package with identical length (0.039" / 1.00mm) and width (0.020" / 0.50mm). The AC0402FR-072R4L has a slightly lower maximum seated height (0.015" / 0.37mm) compared to others (0.016" / 0.40mm), which does not affect PCB assembly compatibility.

Q: Are all substitute parts suitable for automotive applications?

A: Yes. All listed parts carry AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 moisture sensitivity rating, confirming suitability for automotive and industrial environments.

Q: What packaging format is used for these parts?

A: All parts are supplied in Tape & Reel (TR) format, standard for automated PCB assembly processes.
