Substitute Part Grouping Explanation

Substitution eligibility for the CRCW08053R83FNTA is determined by strict equivalence across the following critical parameters:

• Resistance value: 3.83 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)

The RMCF0805FT3R83 manufactured by Stackpole Electronics Inc meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The RMCF0805FT3R83 is a direct functional equivalent to the CRCW08053R83FNTA. Both parts satisfy identical electrical and mechanical specifications required for automotive applications under AEC-Q200 qualification.

The RMCF0805FT3R83 offers ROHS3 compliance, whereas the CRCW08053R83FNTA is RoHS non-compliant. This distinction is relevant for applications subject to RoHS regulatory requirements. The maximum seated height of the RMCF0805FT3R83 (0.026" / 0.65mm) is marginally higher than the CRCW08053R83FNTA (0.020" / 0.50mm), which remains within typical PCB design tolerances for 0805 package footprints.

Selection between these parts should be based on supply availability, RoHS compliance requirements, and design specifications for board clearance.

Frequently Asked Questions (FAQ)

Q: Can the RMCF0805FT3R83 be used as a direct replacement for the CRCW08053R83FNTA?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance, tolerance, power rating, package, temperature coefficient, and operating temperature range. Both meet AEC-Q200 automotive qualification.

Q: What is the difference in height between these two parts?

A: The CRCW08053R83FNTA has a maximum seated height of 0.020" (0.50mm), while the RMCF0805FT3R83 has a maximum seated height of 0.026" (0.65mm). This 0.006" (0.15mm) difference is within standard 0805 package tolerances and does not affect PCB assembly compatibility in typical designs.

Q: Does RoHS compliance affect substitution eligibility?

A: RoHS compliance status does not affect electrical or mechanical substitution eligibility. The RMCF0805FT3R83 is ROHS3 compliant while the CRCW08053R83FNTA is RoHS non-compliant. Selection should be based on regulatory requirements applicable to the end application.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both the CRCW08053R83FNTA and RMCF0805FT3R83 are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.

Q: What is the moisture sensitivity level for these parts?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
