Q: What is the Moisture Sensitivity Level (MSL) for all these parts?

A: All parts, including the RMC1/10-1201FTP and all four substitutes, are rated MSL 1 (Unlimited). This indicates unlimited shelf life without moisture bake-out requirements.

Q: Are all substitute parts ROHS3 compliant?

A: The CRG0805F1K2, CRGCQ0805F1K2, KTR10EZPF1201, and RMCF0805FT1K20 are all confirmed ROHS3 compliant. The RMC1/10-1201FTP RoHS status is not specified in the provided data.

Q: Can these parts be used interchangeably in the same circuit design?

A: Yes. All substitute parts match the RMC1/10-1201FTP in resistance value, tolerance, power rating, temperature coefficient, operating temperature range, package type, and physical dimensions. They are electrically and mechanically interchangeable. Selection among substitutes should be based on application-specific compliance requirements (automotive AEC-Q200, moisture resistance) and supply availability.

Q: What is the temperature coefficient specification, and why is it important?

A: All parts, including the main part and substitutes, have a temperature coefficient of ±100ppm/°C. This specification defines the maximum change in resistance value per degree Celsius across the operating temperature range. The identical specification ensures equivalent performance stability across temperature variations from -55°C to 155°C.
