Substitute Part Grouping Explanation

Substitution eligibility for the CRCW08054K75FKEC is determined by strict equivalence across the following parameters: resistance value (4.75 kOhms), tolerance (±1%), power rating (0.125W), package type (0805 / 2012 Metric), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). All identified substitutes maintain these electrical and mechanical specifications. Automotive-rated variants (AEC-Q200) and non-automotive variants are both included as substitutes, as the core electrical and thermal performance parameters are identical. Packaging format (Tape & Reel) and compliance certifications (RoHS3, REACH Unaffected) are consistent across all substitute options.

Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive qualification, CRCW08054K75FKEA, ERJ-6ENF4751V, RMCF0805FG4K75, and RMCF0805FT4K75 are qualified substitutes. CRCW08054K75FKEA maintains identical Vishay Dale manufacturing with active product status and lowest seated height (0.020"). ERJ-6ENF4751V from Panasonic provides automotive-rated performance with high inventory availability (553,911 units). Stackpole Electronics RMCF series (RMCF0805FG4K75 and RMCF0805FT4K75) offer AEC-Q200 compliance with active status and moderate seated heights (0.026").

For non-automotive applications where AEC-Q200 is not required, CRCW08054K75FKEAC (Vishay Dale CRCW-C series) and CR0805-FX-4751ELF (Bourns moisture-resistant variant) are functionally equivalent. Both maintain active product status and RoHS3 compliance.

CRCW08054K75FKEB, while electrically equivalent, is discontinued at DiGi Electronics and should be avoided for new designs unless legacy stock is specifically required.

All substitutes maintain identical electrical performance (4.75 kΩ ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C) and are packaged in 0805 (2012 Metric) format with MSL 1 rating.

Frequently Asked Questions (FAQ)

Q: Can CRCW08054K75FKEAC replace CRCW08054K75FKEC in automotive applications?

A: CRCW08054K75FKEAC is electrically and mechanically equivalent but lacks AEC-Q200 automotive certification. It is suitable for non-automotive applications. For automotive designs requiring AEC-Q200 compliance, use CRCW08054K75FKEA, ERJ-6ENF4751V, RMCF0805FG4K75, or RMCF0805FT4K75.

Q: What is the difference between RMCF0805FG4K75 and RMCF0805FT4K75?

A: Both parts are manufactured by Stackpole Electronics with identical electrical specifications (4.75 kΩ ±1%, 0.125W, AEC-Q200). The difference lies in the suffix designation (FG vs. FT), which indicates different manufacturing process codes. Both are functionally interchangeable and maintain the same seated height (0.026").

Q: Are there height restrictions when substituting these resistors?

A: Seated height varies across substitutes: CRCW08054K75FKEC and CRCW08054K75FKEA are 0.020" (0.50mm), CRCW08054K75FKEAC and CR0805-FX-4751ELF are 0.024" (0.60mm), RMCF variants are 0.026" (0.65mm), and ERJ-6ENF4751V is 0.028" (0.70mm). Verify PCB layout clearance requirements before substitution if height-constrained applications are involved.

Q: Is CRCW08054K75FKEB still available for use?

A: CRCW08054K75FKEB is discontinued at DiGi Electronics. While 20,694 units remain in stock through other channels, new designs should use active alternatives such as CRCW08054K75FKEA or ERJ-6ENF4751V to ensure long-term supply chain stability.

Q: Do all substitutes meet RoHS3 and REACH compliance?

A: Yes. All listed substitutes are RoHS3 compliant and REACH unaffected, matching the compliance profile of CRCW08054K75FKEC.
