Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1981555 is determined by strict equivalence across the following critical parameters:

• Position Count & Pitch: 13 positions at 0.197" (5.00mm) spacing
• Connector Type & Orientation: Male pin plug with 180° wire entry for free-hanging in-line mounting
• Electrical Ratings: 12A (IEC) / 10A (UL) current capacity; 630V (IEC) / 300V (UL) voltage rating
• Termination Method: Screwless push-in spring mechanism
• Wire Compatibility: 12-26 AWG (0.2-2.5mm²) wire gauge acceptance
• Material & Compliance: Polyamide housing, UL94 V-0 flammability rating, RoHS compliance

The substitute part 1910788 maintains identical electrical and mechanical specifications across all critical parameters, with the primary distinction being active product status and series designation (COMBICON FKIC versus COMBICON FKICS).

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1910788 is the direct functional equivalent for the obsolete 1981555 terminal block plug. Both components share identical electrical ratings, mechanical dimensions, and termination characteristics. The 1910788 is the preferred selection for new designs and replacement applications due to its active product status, ensuring long-term availability and supply chain continuity.

Both parts maintain RoHS compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial control and automation applications. The transition from the COMBICON FKICS series (1981555) to the COMBICON FKIC series (1910788) represents a product line evolution while maintaining full backward compatibility in electrical and mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the 1910788 directly replace the 1981555 in existing installations?

A: Yes. The 1910788 maintains identical electrical ratings (12A IEC, 630V IEC), mechanical dimensions (13 positions, 5mm pitch), wire gauge compatibility (12-26 AWG), and termination method (screwless push-in spring). Physical form factor and mating interface are equivalent.

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

A: The series designation change reflects product line evolution. The FKIC series (1910788) is the current active product line, while FKICS (1981555) is obsolete. Electrical and mechanical specifications remain identical.

Q: Are there packaging differences between these parts?

A: The 1981555 is listed with unspecified packaging, while the 1910788 is supplied in bulk packaging. Functional specifications are unchanged.

Q: Do both parts support the same wire gauge range?

A: Yes. Both the 1981555 and 1910788 accept wire gauges from 12-26 AWG (0.2-2.5mm²) with identical push-in spring termination.

Q: Are both parts RoHS compliant?

A: Yes. Both components are RoHS compliant with UL94 V-0 flammability ratings and MSL 1 moisture sensitivity classification.
