Substitute Part Grouping Explanation

Substitute parts for the CRCW08053R40FNEB are qualified based on the following critical parameters:

• Resistance value: 3.4 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 ~ 155°C (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

Substitute parts must meet all electrical specifications and automotive certifications. Physical dimensions and termination count remain consistent across qualified substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both the CRCW08053R40FNEB and RMCF0805FT3R40 are active production parts with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts should be based on:

Availability and lead time requirements. The RMCF0805FT3R40 currently has higher inventory (10755 units) compared to the CRCW08053R40FNEB (1048 units).

Physical height constraints. The CRCW08053R40FNEB has a maximum seated height of 0.020" (0.50mm), while the RMCF0805FT3R40 has a maximum seated height of 0.026" (0.65mm). Applications with tight vertical clearance requirements should verify compatibility with the substitute part's increased height.

Manufacturer preference and supply chain strategy. Both parts meet identical electrical and compliance specifications and are suitable for direct substitution in automotive applications.

Frequently Asked Questions (FAQ)

Q: Can RMCF0805FT3R40 be used as a direct replacement for CRCW08053R40FNEB?

A: Yes. Both parts meet identical electrical specifications (3.4 Ohms ±1%, 0.125W, ±200ppm/°C, -55°C ~ 155°C) and automotive certifications (AEC-Q200). The primary consideration is the physical height difference: RMCF0805FT3R40 has a maximum seated height of 0.026" (0.65mm) versus 0.020" (0.50mm) for CRCW08053R40FNEB. Verify PCB clearance before substitution.

Q: Are both parts suitable for automotive applications?

A: Yes. Both CRCW08053R40FNEB and RMCF0805FT3R40 carry AEC-Q200 qualification and are rated for automotive use across the operating temperature range of -55°C ~ 155°C.

Q: What is the significance of the 0805 package designation?

A: The 0805 (2012 Metric) package is a standard surface-mount resistor size measuring 0.079" L x 0.049" W (2.00mm x 1.25mm). Both substitute parts use this identical package, ensuring PCB footprint compatibility.

Q: Do these parts require special handling or storage?

A: Both parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life and no special moisture control requirements during storage or handling.

Q: What compliance standards apply to these parts?

A: Both parts are ROHS3 compliant and REACH unaffected. They meet automotive AEC-Q200 qualification standards.
