Substitute Part Grouping Explanation

Substitution for the CRCW0805475RFKEB is determined by strict equivalence across the following parameters: resistance value (475 Ohms), tolerance (±1%), power rating (0.125W minimum), package type (0805), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and automotive qualification (AEC-Q200). Parts are grouped into three categories: direct equivalents (identical specifications and active status), manufacturer-recommended alternatives (same electrical specifications with different series designation), and upgrades (enhanced specifications such as tighter tolerance or higher power rating).

Engineering Selection Recommendations

For direct replacement of the discontinued CRCW0805475RFKEB, select from active Vishay Dale equivalents CRCW0805475RFKEA or CRCW0805475RFKEC. Both maintain identical electrical specifications, AEC-Q200 automotive qualification, and ROHS3 compliance. CRCW0805475RFKEA offers higher inventory availability (38,116 units) compared to CRCW0805475RFKEC (741 units).

For applications requiring ROHS3 compliance and AEC-Q200 qualification without Vishay Dale preference, ERJ-6ENF4750V (Panasonic) and RMCF0805FT475R (Stackpole) are qualified alternatives with substantial inventory (115,207 and 454,278 units respectively).

CRCW0805475RFKTC is electrically equivalent but is RoHS non-compliant and REACH-affected, limiting use to non-regulated applications.

CRCW0805475RDKEAP provides tighter tolerance (±0.5% versus ±1%) while maintaining all other specifications, suitable for applications requiring enhanced precision.

CRCW0805475RFKEAC and CRCW0805475RFKEBC lack AEC-Q200 automotive qualification and are suitable only for non-automotive applications.

ESR10EZPF4750 offers higher power dissipation (0.4W versus 0.125W) with pulse withstanding capability, applicable where thermal margin or transient protection is required.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805475RFKEA directly replace CRCW0805475RFKEB?

A: Yes. Both parts share identical resistance (475 Ohms), tolerance (±1%), power rating (0.125W), package (0805), temperature coefficient (±100ppm/°C), operating range (-55°C to 155°C), and AEC-Q200 automotive qualification. The primary difference is product status: CRCW0805475RFKEB is discontinued while CRCW0805475RFKEA is active.

Q: What is the difference between CRCW0805475RFKEA and CRCW0805475RFKEC?

A: Both are Vishay Dale 475 Ohm ±1% 0.125W 0805 resistors with AEC-Q200 qualification and ROHS3 compliance. The difference is inventory availability: CRCW0805475RFKEA has 38,116 units in stock while CRCW0805475RFKEC has 741 units.

Q: Can I use ERJ-6ENF4750V or RMCF0805FT475R as substitutes?

A: Yes. Both parts meet all electrical and mechanical requirements: 475 Ohms ±1%, 0.125W, 0805 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, and AEC-Q200 automotive qualification. They are cross-manufacturer alternatives with active status and ROHS3 compliance.

Q: Why would I choose CRCW0805475RDKEAP over the standard ±1% parts?

A: CRCW0805475RDKEAP provides ±0.5% tolerance instead of ±1%, offering tighter resistance accuracy. All other specifications remain identical. Selection depends on circuit requirements for precision.

Q: Is CRCW0805475RFKTC a suitable substitute?

A: CRCW0805475RFKTC is electrically equivalent but is RoHS non-compliant and REACH-affected. Use only in applications where regulatory compliance is not required.

Q: What is the difference between CRCW0805475RFKEAC/RFKEBC and the AEC-Q200 qualified parts?

A: CRCW0805475RFKEAC and CRCW0805475RFKEBC lack AEC-Q200 automotive qualification. They are suitable for commercial and industrial applications but not for automotive use. All other electrical specifications are identical to the qualified parts.

Q: Can ESR10EZPF4750 replace the standard 0.125W parts?

A: ESR10EZPF4750 is electrically compatible (475 Ohms ±1%, 0805 package, AEC-Q200) but has higher power rating (0.4W versus 0.125W) and pulse withstanding capability. It is a functional upgrade suitable for applications requiring greater thermal margin or transient protection. Physical dimensions are compatible with 0805 footprints.
