Substitute Part Grouping Explanation

Substitution eligibility for the CRCW04029R53FNED is determined by the following criteria:

Resistance value must be 9.53 Ohms with ±1% tolerance. Power rating must be 0.063W (1/16W) minimum. Package must be 0402 (1005 Metric) with identical mechanical dimensions. Composition must be thick film. Automotive AEC-Q200 qualification is required. Operating temperature range must span -55°C to 155°C minimum. RoHS3 compliance and MSL 1 rating must be maintained. Termination count must be 2.

The CRCW04029R53FKED meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both CRCW04029R53FNED and CRCW04029R53FKED are active production components manufactured by Vishay Dale with full AEC-Q200 automotive qualification. Both parts maintain ROHS3 compliance and MSL 1 rating, suitable for unrestricted moisture exposure conditions. The primary distinction is the temperature coefficient specification: CRCW04029R53FKED provides ±100ppm/°C compared to ±200ppm/°C for CRCW04029R53FNED. This represents improved temperature stability in the substitute part. Both components are electrically and mechanically interchangeable within the specified operating temperature range of -55°C to 155°C.

Frequently Asked Questions (FAQ)

Q: Can CRCW04029R53FKED replace CRCW04029R53FNED in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification, share identical electrical specifications (9.53 Ohms ±1%, 0.063W), and use the same 0402 (1005 Metric) package with matching mechanical dimensions. The substitute part offers improved temperature coefficient performance.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components measure 0.039" L x 0.020" W (1.00mm x 0.50mm) with maximum seated height of 0.016" (0.40mm). They are mechanically interchangeable in PCB layouts designed for 0402 package format.

Q: What is the significance of the temperature coefficient difference?

A: The CRCW04029R53FKED has a temperature coefficient of ±100ppm/°C versus ±200ppm/°C for CRCW04029R53FNED. This means the substitute part exhibits lower resistance drift across the -55°C to 155°C operating range, providing enhanced stability in temperature-sensitive applications.

Q: Do both parts require the same handling and storage conditions?

A: Yes. Both components carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard ESD precautions and dry storage conditions apply to both parts.

Q: Are there inventory considerations for substitution?

A: CRCW04029R53FKED has 26064 pieces in stock compared to 1061 pieces for CRCW04029R53FNED, providing greater availability for the substitute part.
