Parameter Comparison

Engineering Selection Recommendations

The RC0805FR-071R24L from YAGEO is a qualified substitute for the CRCW08051R24FNTA. Both parts share identical electrical specifications and package dimensions. The YAGEO part offers ROHS3 compliance, which may be advantageous for applications subject to RoHS regulations. The CRCW08051R24FNTA carries AEC-Q200 automotive qualification, while the RC0805FR-071R24L is specified as moisture resistant. Selection between these parts should be based on specific compliance requirements and automotive qualification needs of the end application.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-071R24L replace CRCW08051R24FNTA in all applications?

A: The RC0805FR-071R24L matches all critical electrical parameters (resistance, tolerance, power rating, temperature coefficient, operating temperature range) and package specifications. However, applications requiring AEC-Q200 automotive qualification should verify that the YAGEO part meets specific automotive standards required by the design.

Q: What is the difference in height between these two parts?

A: The CRCW08051R24FNTA has a maximum seated height of 0.020" (0.50mm), while the RC0805FR-071R24L has a maximum seated height of 0.024" (0.60mm). This 0.004" (0.10mm) difference should be evaluated for applications with height constraints or tight PCB assembly tolerances.

Q: Are there RoHS compliance differences between these parts?

A: The CRCW08051R24FNTA is RoHS non-compliant, while the RC0805FR-071R24L is ROHS3 compliant. Applications subject to RoHS regulations should use the YAGEO part.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes, both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity limitations for storage and handling.

Q: Are the physical footprints identical?

A: Yes, both parts use the 0805 (2012 Metric) package with identical length and width dimensions of 0.079" x 0.049" (2.00mm x 1.25mm), ensuring PCB footprint compatibility.
