Parameter Comparison

Engineering Selection Recommendations

RMCF1206FT4R75 (Stackpole Electronics Inc): This part qualifies as a direct substitute with enhanced automotive qualification. The RMCF1206FT4R75 meets all electrical and mechanical requirements with AEC-Q200 certification, indicating suitability for automotive applications. Temperature coefficient of ±200ppm/°C provides improved stability compared to the main part. Maximum seated height of 0.028" (0.70mm) remains within acceptable 1206 package tolerances. ROHS3 compliance and MSL 1 rating match the original specification. This substitute is appropriate for applications requiring automotive-grade reliability or where tighter temperature coefficient performance is beneficial.

RC1206FR-074R75L (YAGEO): This part qualifies as an upgrade substitute with equivalent electrical performance and moisture-resistant characteristics matching the main part. Temperature coefficient of ±200ppm/°C provides improved thermal stability. Physical dimensions of 0.122" L x 0.063" W (3.10mm x 1.60mm) represent a minor reduction in length while maintaining 1206 package classification and seated height of 0.026" (0.65mm). ROHS3 compliance and MSL 1 rating are identical to the original. This substitute is appropriate for general industrial applications where improved temperature coefficient performance is desired without automotive-specific requirements.

Both substitutes maintain full electrical equivalence and mechanical compatibility with the RC3216F4R75CS within the 1206 package footprint and assembly process parameters.

Frequently Asked Questions (FAQ)

Q: Can RMCF1206FT4R75 be used in place of RC3216F4R75CS without circuit redesign?

A: Yes. Both parts share identical electrical specifications (4.75 Ohms ±1%, 0.25W) and operate across the same temperature range (-55°C ~ 155°C). The 1206 package footprint is identical. The maximum seated height difference of 0.002" (0.05mm) is within standard PCB assembly tolerances and does not require design modification.

Q: What is the difference between RC1206FR-074R75L and RC3216F4R75CS?

A: Both parts are electrically equivalent with 4.75 Ohms ±1% resistance and 0.25W power rating. The RC1206FR-074R75L features a ±200ppm/°C temperature coefficient compared to ±300ppm/°C for the RC3216F4R75CS, providing improved thermal stability. Physical length differs by 0.004" (0.10mm), which is within 1206 package specification tolerance.

Q: Are all three parts suitable for moisture-sensitive applications?

A: Yes. All three parts carry Moisture Sensitivity Level 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. They are suitable for applications without special moisture control requirements during storage, handling, or assembly.

Q: Does the Stackpole RMCF1206FT4R75 require different assembly parameters?

A: No. The RMCF1206FT4R75 uses standard 1206 package assembly parameters identical to the RC3216F4R75CS. Tape & Reel packaging format is compatible with standard pick-and-place equipment. No reflow profile or assembly process modifications are required.

Q: Which substitute offers the best long-term stability?

A: Both RMCF1206FT4R75 and RC1206FR-074R75L offer ±200ppm/°C temperature coefficient, compared to ±300ppm/°C for the main part. This represents a 33% improvement in temperature stability. Selection between these two substitutes should be based on application-specific requirements and supply availability rather than thermal performance, as both provide equivalent improvement.

Q: Are all parts RoHS3 compliant?

A: Yes. RC3216F4R75CS, RMCF1206FT4R75, and RC1206FR-074R75L are all ROHS3 Compliant with REACH Unaffected status, meeting current environmental and regulatory requirements.
