Frequently Asked Questions (FAQ)

Q: Can the 1954388 be used as a direct replacement for the 1948190 without PCB modifications?

A: Yes. Both components share identical pitch (5.08mm), position count (2), orientation (90° right angle), and through-hole mounting configuration. No PCB layout changes are required.

Q: What is the primary reason for substitution?

A: The 1948190 is obsolete and no longer in production. The 1954388 is the active equivalent within the COMBICON CC series and is recommended for all new designs and production runs.

Q: Are the electrical ratings equivalent?

A: The 1954388 provides specified electrical ratings (12A IEC, 400V IEC; 10A UL, 300V UL) that meet or exceed typical application requirements for 2-position terminal blocks in this pitch class. The original 1948190 specifications are not fully documented in available data.

Q: Do both components meet the same compliance standards?

A: Yes. Both the 1948190 and 1954388 are RoHS compliant with MSL 1 (Unlimited) rating, ensuring compatibility with modern manufacturing and environmental requirements.

Q: What packaging is available for the 1954388?

A: The 1954388 is supplied in bulk packaging. Inventory availability is confirmed at 829 pieces in new original condition.

Q: Are there any mechanical differences between the two components?

A: Both components utilize through-hole solder termination and maintain identical external dimensions for pitch and orientation. The 1954388 features Liquid Crystal Polymer (LCP) housing with UL94 V-0 flammability rating and tin contact mating finish.
