Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CRL0805-FW-R470ELF is determined by the following critical parameters:

• Resistance Value: Must be 470 mOhms
• Tolerance: Must be ±1%
• Package Format: Must be 0805 (2012 Metric)
• Composition: Must be Thick Film
• Temperature Coefficient: Must be ±200ppm/°C
• RoHS Compliance: Must be ROHS3 Compliant
• Moisture Sensitivity Level: Must be MSL 1 or better

The RMCF0805FTR470 manufactured by Stackpole Electronics Inc. meets all substitution criteria. While this part is rated for 0.125W (1/8W) power dissipation compared to the 0.25W rating of the main part, it satisfies all electrical and mechanical compatibility requirements. The lower power rating does not prevent substitution in applications where the actual power dissipation does not exceed the substitute part's capability.

Parameter Comparison

Engineering Selection Recommendations

The RMCF0805FTR470 is a valid substitute for the CRL0805-FW-R470ELF based on matching electrical specifications, package format, and compliance certifications. Both parts are Active products with ROHS3 compliance and MSL Level 1 ratings.

The primary consideration for substitution is the power rating differential. The CRL0805-FW-R470ELF is rated for 0.25W, while the RMCF0805FTR470 is rated for 0.125W. Substitution is appropriate only when the actual power dissipation in the application does not exceed 0.125W. The RMCF0805FTR470 additionally carries AEC-Q200 automotive qualification, which may provide additional reliability assurance in automotive or high-reliability applications.

Frequently Asked Questions (FAQ)

Q: Can the RMCF0805FTR470 be used as a direct replacement for the CRL0805-FW-R470ELF?

A: Yes, provided the actual power dissipation in your application does not exceed 0.125W. Both parts share identical resistance, tolerance, package format, composition, and temperature coefficient specifications. The lower power rating of the substitute part is the only limiting factor.

Q: What is the impact of the power rating difference?

A: The CRL0805-FW-R470ELF is rated for 0.25W dissipation, while the RMCF0805FTR470 is rated for 0.125W. If your circuit design requires the full 0.25W capability, the substitute part is not suitable. Calculate actual power dissipation using P = I²R to determine compatibility.

Q: Are the physical dimensions compatible?

A: Yes. Both parts use the 0805 (2012 Metric) package with identical footprint dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm). Height differences are minimal (0.024" maximum for the main part versus 0.026" maximum for the substitute), and both are within standard PCB assembly tolerances.

Q: Does the extended operating temperature range of the substitute part affect compatibility?

A: No. The RMCF0805FTR470 operates from -55°C to 155°C, which encompasses the -55°C to 125°C range of the CRL0805-FW-R470ELF. The extended upper temperature limit provides additional margin but does not impact substitution in applications requiring only the original temperature range.

Q: What does AEC-Q200 certification mean for the substitute part?

A: AEC-Q200 is an automotive industry qualification standard. The RMCF0805FTR470 meets this standard, indicating suitability for automotive applications. This certification is not required for general industrial or consumer applications but may be beneficial if your design requires automotive-grade reliability.

Q: Are both parts RoHS compliant?

A: Yes. Both the CRL0805-FW-R470ELF and RMCF0805FTR470 are ROHS3 compliant and carry MSL Level 1 ratings, indicating full compliance with current environmental and moisture sensitivity standards.
