Engineering Selection Recommendations

All substitute and equivalent resistors listed have an Active product status and provide REACH unaffected compliance as supplied. Each part maintains an MSL of 1 (Unlimited) and retains conformity to the original's RoHS/REACH status where reported. These criteria allow these parts to be selected for use in assemblies requiring RoHS and REACH compliance and for applications that mandate no restrictive moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q1: What are the essential criteria for selecting a substitute for RMC1/10K3003FTP?
A1: The substitute must match the original's resistance value, tolerance, power rating, temperature coefficient, package/case size, and composition type.
