Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CRCW08051R91FNTA is determined by strict equivalence in the following parameters:

• Resistance value: 1.91 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package format: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 155°C
• Number of terminations: 2

The RC0805FR-071R91L from YAGEO meets all these electrical and mechanical requirements and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the CRCW08051R91FNTA and RC0805FR-071R91L are active products with equivalent electrical and mechanical specifications. The CRCW08051R91FNTA carries AEC-Q200 automotive qualification and is RoHS non-compliant. The RC0805FR-071R91L is ROHS3 compliant and features moisture-resistant construction. Selection between these parts depends on specific application requirements regarding automotive certification and regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-071R91L replace CRCW08051R91FNTA in all applications?

A: Both parts share identical electrical specifications (1.91 Ohms ±1%, 0.125W, ±200ppm/°C, -55°C to 155°C) and mechanical dimensions (0805 package, 2.00mm x 1.25mm). The primary difference is regulatory compliance: CRCW08051R91FNTA carries AEC-Q200 automotive qualification while RC0805FR-071R91L is ROHS3 compliant. Application requirements determine suitability.

Q: What is the height difference between these parts?

A: CRCW08051R91FNTA has a maximum seated height of 0.020" (0.50mm), while RC0805FR-071R91L has a maximum seated height of 0.024" (0.60mm). This 0.004" (0.10mm) difference may be relevant for space-constrained PCB designs.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 0805 (2012 Metric) package with dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm). PCB footprints are interchangeable.

Q: What composition are these resistors?

A: Both are thick film chip resistors. CRCW08051R91FNTA features automotive AEC-Q200 thick film construction, while RC0805FR-071R91L features moisture-resistant thick film construction.
