Frequently Asked Questions (FAQ)

Q: Can RMCF1206FG1M82 or RMCF1206FT1M82 be used as direct replacements for RMC1/8-1824FTP?

A: Yes. Both Stackpole parts match all critical electrical parameters: 1.82 MOhms resistance, ±1% tolerance, 0.25W power rating, ±200ppm/°C temperature coefficient, and -55°C to 155°C operating range. The 1206 package dimensions are compatible. The primary difference is AEC-Q200 automotive qualification, which adds reliability assurance for automotive applications.

Q: What is the difference between RC1206FR-071M82L and the main part RMC1/8-1824FTP?

A: The YAGEO RC1206FR-071M82L provides superior temperature coefficient performance at ±100ppm/°C versus ±200ppm/°C for the main part, and includes moisture-resistant construction. All other electrical and mechanical parameters are identical. This part is suitable for applications requiring tighter temperature stability.

Q: Are there physical dimension differences between these parts?

A: Minor dimensional variations exist within 1206 package tolerances. RMC1/8-1824FTP and RC1206FR-071M82L measure 0.122" L x 0.063" W (3.10mm x 1.60mm). Stackpole parts (RMCF series) measure 0.126" L x 0.063" W (3.20mm x 1.60mm). Height differences are also within standard tolerances: 0.025" (0.65mm) for Kamaya and YAGEO versus 0.028" (0.70mm) for Stackpole. These variations are acceptable for standard PCB assembly processes.

Q: Which substitute part should be selected for automotive applications?

A: RMCF1206FG1M82 or RMCF1206FT1M82 are appropriate for automotive applications due to AEC-Q200 qualification. Both parts provide identical electrical performance with automotive-grade reliability assurance.

Q: What is the MSL rating and why is it important?

A: All parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations. These components can be stored indefinitely without special moisture control measures and do not require baking before soldering.

Q: Are all substitute parts ROHS compliant?

A: RMCF1206FG1M82, RMCF1206FT1M82, and RC1206FR-071M82L are ROHS3 compliant. The main part RMC1/8-1824FTP is REACH Unaffected. All parts meet environmental compliance requirements for their respective markets.
