Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CRCW08058R66FNTA is determined by the following critical parameters:

• Resistance value: 8.66 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Package: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (minimum requirement)
• Moisture sensitivity: MSL 1 (exact match required)

All identified substitute parts meet these electrical and mechanical parameters. Variations in physical dimensions (height), RoHS compliance status, and feature certifications (automotive vs. moisture resistant) do not affect functional substitutability within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

All three parts are active products with identical electrical specifications and package dimensions suitable for direct substitution in 0805 footprints. Selection between alternatives should be based on the following factors:

RMCF0805FT8R66 (Stackpole Electronics Inc) is ROHS3 compliant and carries AEC-Q200 automotive certification, matching the original part's automotive qualification. This part offers the highest inventory availability at 8,399 pieces.

RC0805FR-078R66L (YAGEO) is ROHS3 compliant with moisture-resistant thick film composition. This part provides the largest inventory stock at 10,763 pieces and is REACH unaffected.

CRCW08058R66FNTA (Vishay Dale) is the original specification part with the lowest seated height at 0.50mm. This part is RoHS non-compliant and REACH affected, with 829 pieces in stock.

For applications requiring RoHS3 compliance or REACH compliance, RMCF0805FT8R66 or RC0805FR-078R66L are appropriate selections. For applications with strict height constraints in dense PCB layouts, the original Vishay Dale part offers a 0.15mm height advantage over the Stackpole alternative and 0.10mm advantage over the YAGEO alternative.

Frequently Asked Questions (FAQ)

Q: Can RMCF0805FT8R66 replace CRCW08058R66FNTA in automotive applications?

A: Yes. Both parts are rated for automotive use under AEC-Q200 standard with identical electrical parameters (8.66 Ohms ±1%, 0.125W, ±200ppm/°C, -55°C to 155°C). The Stackpole part is additionally ROHS3 compliant.

Q: What is the maximum height difference between substitute parts?

A: The maximum seated height difference is 0.006" (0.15mm) between the Vishay Dale original at 0.50mm and the Stackpole part at 0.65mm. The YAGEO part measures 0.60mm seated height.

Q: Are all substitute parts suitable for high-density PCB layouts?

A: All parts use the same 0805 (2012 Metric) footprint. Height variations of 0.15mm maximum are negligible for standard PCB assembly processes. Verify specific design constraints if height clearance is critical.

Q: What is the difference between AEC-Q200 and moisture-resistant certifications?

A: AEC-Q200 is an automotive qualification standard. Moisture-resistant is a material feature. These are independent certifications. RMCF0805FT8R66 carries AEC-Q200; RC0805FR-078R66L carries moisture-resistant designation. Both are suitable for their respective application requirements.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the design does not have specific constraints on RoHS compliance, REACH compliance, or physical height. All parts meet the core electrical and mechanical parameters of the 0805 8.66 Ohm ±1% 0.125W thick film resistor specification.
