Frequently Asked Questions (FAQ)

Q: Can RMCF2010FT120K replace ERJ-S1DF1203U in automotive applications?

A: Yes. Both components share identical resistance (120 kOhms), tolerance (±1%), power rating (0.75W), package (2010), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and AEC-Q200 automotive qualification.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.197" L x 0.098" W (5.00mm x 2.50mm) with a maximum seated height of 0.028" (0.70mm), ensuring PCB layout compatibility.

Q: Do both parts meet RoHS requirements?

A: Yes. Both ERJ-S1DF1203U and RMCF2010FT120K are ROHS3 compliant.

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

A: Both components have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there differences in the anti-sulfur coating?

A: The ERJ-S1DF1203U explicitly includes anti-sulfur coating. The RMCF2010FT120K specification does not list this feature. Verify anti-sulfur requirements for your specific application before substitution.
