Substitute Part Grouping Explanation

Substitution of the CRCW08052R10FNTA is permissible when the replacement part meets the following criteria:

• Resistance value: 2.1 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W) minimum
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C minimum
• Termination count: 2
• Packaging format: Tape & Reel (TR)

The RC0805FR-072R1L from YAGEO satisfies all electrical and mechanical parameters required for direct substitution. Both parts share identical resistance, tolerance, power rating, package dimensions, and operating temperature specifications. Physical dimensions remain compatible within standard PCB assembly tolerances.

Parameter Comparison

Engineering Selection Recommendations

The CRCW08052R10FNTA is an active product with automotive AEC-Q200 qualification. The RC0805FR-072R1L provides equivalent electrical performance and mechanical compatibility for applications requiring a 2.1 Ohm 0805 chip resistor. The YAGEO substitute is ROHS3 compliant and moisture resistant, offering enhanced environmental protection compared to the original part. Both components are suitable for -55°C to 155°C operating environments and maintain ±1% tolerance across the specified temperature range. Selection between these parts should be based on supply availability, compliance requirements, and specific application environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-072R1L replace CRCW08052R10FNTA in automotive applications?

A: Yes. Both parts meet identical electrical specifications (2.1 Ohms ±1%, 0.125W) and operate across -55°C to 155°C. The YAGEO part is moisture resistant and ROHS3 compliant. Verify that your application does not require specific AEC-Q200 qualification, as only the Vishay Dale part carries this certification.

Q: Are the physical dimensions compatible?

A: Yes. Both parts use the 0805 (2012 Metric) package with identical length and width (2.00mm x 1.25mm). The seated height differs by 0.004" (0.10mm), which remains within standard PCB assembly tolerances and does not affect board-level compatibility.

Q: What is the difference in RoHS compliance?

A: The CRCW08052R10FNTA is RoHS non-compliant. The RC0805FR-072R1L is ROHS3 compliant, making it suitable for applications with RoHS requirements.

Q: Can these parts be used interchangeably in production?

A: Yes, provided that your design does not mandate AEC-Q200 certification. Both parts deliver equivalent electrical performance and are mechanically compatible. Confirm with your supply chain and quality requirements before implementing substitution.

Q: What is the moisture sensitivity level?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
