Substitute Part Grouping Explanation

Substitution of the CRCW08054R30FKEC is determined by strict equivalence across the following critical parameters:

• Resistance value: 4.3 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
• Automotive compliance: AEC-Q200
• RoHS compliance: ROHS3

The substitute part CRCW08054R30FKEA matches all electrical and mechanical specifications, differing only in packaging designation suffix. Both parts are manufactured by Vishay Dale within the CRCW series and maintain identical functional performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Selection between these parts is based on packaging designation and inventory availability. The CRCW08054R30FKEA offers higher inventory availability (28,604 pieces) compared to CRCW08054R30FKEC (963 pieces), making it suitable for high-volume procurement requirements. Both parts maintain identical electrical performance, mechanical fit, and regulatory compliance for automotive applications.

Frequently Asked Questions (FAQ)

Q: Can CRCW08054R30FKEA be used as a direct replacement for CRCW08054R30FKEC?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance, tolerance, power rating, package dimensions, and automotive AEC-Q200 certification. The difference in part number suffix reflects packaging designation only.

Q: What determines substitution eligibility for this 0805 chip resistor?

A: Substitution is valid when the alternative part maintains the same resistance value (4.3 Ohms), tolerance (±1%), power rating (0.125W), package type (0805 / 2012 Metric), composition (Thick Film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and automotive compliance (AEC-Q200).

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical RoHS3 compliance, REACH unaffected status, and AEC-Q200 automotive qualification. Moisture sensitivity level is 1 (Unlimited) for both parts.

Q: What is the physical compatibility of these substitute parts?

A: Both parts are housed in 0805 (2012 Metric) package with identical dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm) and maximum seated height of 0.020" (0.50mm). PCB footprints and assembly processes are identical.
