Frequently Asked Questions (FAQ)

Q: Why is the RS-FCN40S-G4 marked as obsolete? A: Obsolete status indicates the manufacturer has discontinued this specific model. Current inventory may be available through authorized distributors, but long-term availability cannot be guaranteed.

Q: What parameters must a substitute part match? A: A substitute must function as a terminal block adapter, maintain compatibility with the RS series interface standard, and preserve REACH and ECCN compliance classifications.

Q: Where can equivalent parts be sourced? A: Contact Weidmüller directly or authorized terminal block distributors for current alternatives within the RS series that maintain functional and compliance equivalence.

Q: Is RoHS compliance required for substitution? A: The original part lists RoHS status as not applicable. Any substitute should maintain this same compliance posture unless system requirements have changed.
