Substitute Part Grouping Explanation

Substitution eligibility for the CRCW08051R37FNTA is determined by strict equivalence across the following parameters:

• Resistance value: 1.37 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package type: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 155°C
• Termination count: 2
• Moisture sensitivity level: 1 (Unlimited)

The RC0805FR-071R37L from YAGEO meets all these electrical and mechanical requirements and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the CRCW08051R37FNTA and RC0805FR-071R37L are active production parts meeting identical electrical specifications. The CRCW08051R37FNTA carries AEC-Q200 automotive qualification. The RC0805FR-071R37L is RoHS3 compliant and REACH unaffected, whereas the CRCW08051R37FNTA is RoHS non-compliant and REACH affected. Selection between these parts should be based on specific compliance requirements of the application and availability constraints.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-071R37L replace CRCW08051R37FNTA in all applications?

A: Both parts share identical electrical parameters (1.37 Ohms ±1%, 0.125W, ±200ppm/°C, -55°C to 155°C) and package dimensions. The primary difference is regulatory compliance status. Applications requiring AEC-Q200 qualification must use the CRCW08051R37FNTA. Applications with RoHS3 or REACH compliance requirements may require the RC0805FR-071R37L.

Q: Are there physical compatibility concerns between these parts?

A: Both parts use the 0805 (2012 Metric) package with identical length and width (0.079" x 0.049"). The seated height differs by 0.004" (0.10mm), with RC0805FR-071R37L at 0.024" (0.60mm) maximum versus CRCW08051R37FNTA at 0.020" (0.50mm) maximum. This difference is within typical PCB assembly tolerances and does not affect electrical performance or mechanical fit in standard 0805 footprints.

Q: What is the significance of the ±200ppm/°C temperature coefficient?

A: The temperature coefficient specifies the resistance change per degree Celsius across the operating range. Both parts maintain this specification across -55°C to 155°C, ensuring stable performance in automotive and industrial temperature environments.

Q: Are both parts suitable for automotive applications?

A: The CRCW08051R37FNTA carries explicit AEC-Q200 automotive qualification. The RC0805FR-071R37L does not list AEC-Q200 qualification in the provided specifications. Automotive applications requiring AEC-Q200 certification must use the CRCW08051R37FNTA.
