Engineering Selection Recommendations

The Phoenix Contact 1873430 is the direct equivalent substitute for the obsolete 1981827. Both components are manufactured by Phoenix Contact and share identical electrical ratings, physical dimensions, and functional specifications. The primary distinction is product status: the 1873430 maintains active production status, ensuring reliable procurement channels and manufacturer support.

For applications currently using the 1981827, direct replacement with the 1873430 is supported by complete parameter equivalence. Both components comply with RoHS regulations and carry UL94 V-0 flammability certification, meeting the same safety and environmental standards. The transition from the COMBICON FKICS series (1981827) to the COMBICON FKIC series (1873430) represents a product line evolution while maintaining full backward compatibility in electrical and mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the 1873430 directly replace the 1981827 in existing applications?

A: Yes. The 1873430 is electrically and mechanically equivalent to the 1981827. Both components support identical current ratings (12A IEC, 10A UL), voltage ratings (630V IEC, 300V UL), wire gauges (12-26 AWG), and physical configurations. Direct substitution is supported without circuit or mechanical redesign.

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

A: The FKIC series represents the current production line, while FKICS is the obsolete predecessor. The 1873430 (FKIC) maintains full compatibility with applications designed for the 1981827 (FKICS) across all specified electrical and mechanical parameters.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1981827 and 1873430 are RoHS compliant and carry UL94 V-0 flammability certification, meeting current environmental and safety standards.

Q: What wire gauges are supported?

A: Both components support wire gauges from 12-26 AWG (0.2-2.5mm²) with 10mm wire strip length and push-in spring termination.

Q: Why is the 1981827 listed as obsolete?

A: The 1981827 has been superseded by the 1873430 within Phoenix Contact's product portfolio. The 1873430 offers the same functionality with active manufacturing and support status.

Q: Are there packaging differences between these parts?

A: The 1981827 packaging is not specified in available data. The 1873430 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.
