Engineering Selection Recommendations

The Phoenix Contact 1873485 is the direct active equivalent for the obsolete 1981872. Selection of the 1873485 is based on:

Product Status: The 1981872 is classified as obsolete. The 1873485 is active and currently manufactured, ensuring long-term availability and supply chain continuity.

Compliance & Certifications: Both parts maintain identical RoHS compliance and UL94 V-0 flammability ratings, meeting regulatory requirements for industrial terminal block applications.

Electrical & Mechanical Compatibility: All electrical ratings (12A IEC, 10A UL, 630V IEC, 300V UL) and mechanical specifications (15 positions, 5.08mm pitch, 180° wire entry, push-in termination) are identical, ensuring direct functional replacement without circuit redesign or mechanical modification.

Series Transition: The transition from COMBICON FKICS to COMBICON FKIC series represents a product line consolidation by Phoenix Contact. The specifications remain unchanged for this configuration.

Frequently Asked Questions (FAQ)

Q: Can the 1873485 directly replace the 1981872 in existing assemblies?

A: Yes. The 1873485 is mechanically and electrically identical to the 1981872. All mounting dimensions, electrical ratings, wire gauge compatibility, and termination methods are equivalent. No circuit modifications or mechanical redesign is required.

Q: What is the difference between the COMBICON FKICS and COMBICON FKIC series?
