Substitute Part Grouping Explanation

Substitution of the CRCW0805953RFKEB is determined by strict equivalence across the following critical parameters:

Resistance value: 953 Ohms
Tolerance: ±1%
Power rating: 0.125W (1/8W)
Package: 0805 (2012 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C to 155°C
Termination count: 2
RoHS and environmental compliance: ROHS3 Compliant, MSL 1

All substitute parts listed meet these electrical and mechanical specifications. Physical dimensions (length, width, and seated height) may vary within acceptable tolerances for 0805 package components. Packaging format (Tape & Reel or Cut Tape) does not affect electrical equivalence but may impact procurement and assembly processes.

Engineering Selection Recommendations

CRCW0805953RFKEA (Vishay Dale) is the primary direct substitute, offering identical electrical specifications and the highest inventory availability at 12834 units. Both CRCW0805953RFKEB and CRCW0805953RFKEA are from the same manufacturer and series, differing only in packaging designation.

ERJ-6ENF9530V (Panasonic Electronic Components) provides the largest inventory pool at 55306 units and maintains full AEC-Q200 automotive compliance. The seated height is 0.028" compared to 0.020" for the primary part, which remains within acceptable 0805 package tolerances.

RMCF0805FT953R (Stackpole Electronics Inc) is an active alternative with 3176 units available and a seated height of 0.026".

CR0805-FX-9530ELF (Bourns Inc.) is rated for moisture-resistant applications rather than automotive AEC-Q200, with lower inventory at 730 units.

MCR10ERTF9530 (Rohm Semiconductor) is discontinued at DiGi Electronics and should not be selected for new designs requiring long-term availability.

All active alternatives maintain ROHS3 compliance, MSL 1 rating, and identical electrical performance within the specified tolerance and temperature range.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805953RFKEA be used as a direct replacement for CRCW0805953RFKEB?

A: Yes. Both parts are manufactured by Vishay Dale, share identical electrical specifications (953 Ω ±1%, 0.125W, ±100ppm/°C), and are rated for -55°C to 155°C operation. The difference in part number suffix reflects packaging designation only. Both are AEC-Q200 compliant and ROHS3 certified.

Q: Are there differences in physical dimensions between substitute parts?

A: Seated height varies slightly among manufacturers: CRCW0805953RFKEB at 0.020" (0.50mm), ERJ-6ENF9530V at 0.028" (0.70mm), RMCF0805FT953R at 0.026" (0.65mm), and CR0805-FX-9530ELF at 0.024" (0.60mm). All remain within standard 0805 package tolerances. Length and width are consistent at 0.079" × 0.049" (2.00mm × 1.25mm) across all parts.

Q: What is the difference between AEC-Q200 rated and moisture-resistant rated parts?

A: CRCW0805953RFKEB, CRCW0805953RFKEA, ERJ-6ENF9530V, RMCF0805FT953R, and MCR10ERTF9530 are AEC-Q200 automotive qualified. CR0805-FX-9530ELF is rated for moisture resistance without automotive qualification. Selection depends on application requirements.

Q: Why is MCR10ERTF9530 listed if it is discontinued?

A: MCR10ERTF9530 is documented as a known equivalent but is discontinued at DiGi Electronics. It should not be selected for new designs. Active alternatives provide equivalent performance with assured long-term availability.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect electrical performance?

A: No. Packaging format affects procurement, storage, and assembly processes only. Electrical specifications and performance are identical regardless of packaging format.

Q: Can these parts be used interchangeably in automotive applications?

A: CRCW0805953RFKEB, CRCW0805953RFKEA, ERJ-6ENF9530V, RMCF0805FT953R, and MCR10ERTF9530 are all AEC-Q200 qualified and suitable for automotive use. CR0805-FX-9530ELF is not automotive qualified and should be evaluated against specific application requirements.
