Substitute Part Grouping Explanation

Substitution eligibility for terminal block plugs is determined by strict alignment of electrical and mechanical parameters. The primary criteria are:

Connector Type & Gender: Both parts must be plugs with male pins
Position Count & Pitch: Identical 11-position configuration at 0.200" (5.08mm) pitch ensures mechanical compatibility
Wire Entry Orientation: Both maintain 180° free-hanging in-line configuration
Electrical Ratings: Current and voltage ratings must meet or exceed application requirements
Wire Gauge Compatibility: Supported wire ranges must accommodate the intended conductor sizes
Termination Method: Screwless push-in spring termination provides equivalent connection reliability
Housing Material & Color: Polyamide construction and green color ensure physical and environmental consistency
Compliance Standards: RoHS compliance and UL94 V-0 flammability rating maintained across substitutes

Phoenix Contact 1873443 qualifies as a direct substitute based on these parameters.

Engineering Selection Recommendations

Phoenix Contact 1873443 is the appropriate substitute for obsolete part 1981830 based on the following engineering criteria:

Mechanical Compatibility: Both components share identical connector geometry, pitch, position count, and mounting configuration. Physical interchangeability is confirmed.

Electrical Performance: The substitute maintains IEC current rating at 12A and UL ratings at 10A/300V. The IEC voltage rating of 1873443 is 320V compared to 630V for the main part. This difference is acceptable for applications operating at or below 320V IEC. Applications requiring the full 630V IEC rating must retain the original part or identify alternative solutions.

Termination & Wire Compatibility: Identical screwless push-in spring termination and wire gauge support (12-26 AWG / 0.2-2.5mm²) ensure equivalent connection performance and installation procedures.

Compliance & Reliability: Both parts maintain UL94 V-0 flammability rating, RoHS compliance, and tin contact mating finish. The substitute is an active product with current manufacturing support, eliminating obsolescence risk.

Series Alignment: Both components belong to the Phoenix Contact COMBICON family, confirming design continuity and interoperability within the product ecosystem.

Frequently Asked Questions (FAQ)

Q: Can 1873443 directly replace 1981830 in all applications?

A: Direct replacement is valid for applications operating at IEC voltages of 320V or below. Applications requiring 630V IEC operation must verify that 1873443's 320V rating is sufficient, or source alternative components. All other electrical and mechanical parameters are identical.

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

A: Both series represent the same product family with compatible connector geometry and electrical characteristics. The series designation reflects manufacturing evolution. The FKIC series (1873443) represents the current active product line.

Q: Are the termination methods equivalent?

A: Both parts use screwless push-in spring termination. The main part 1981830 includes an additional leg spring option, while 1873443 uses push-in spring only. For applications requiring leg spring termination specifically, compatibility must be verified against the actual connector housing design.

Q: Does the substitute support the same wire gauge range?

A: Yes. Both 1981830 and 1873443 support 12-26 AWG (0.2-2.5mm²) wire gauges with identical 10mm wire strip length.

Q: Is 1873443 RoHS compliant?

A: Yes. Phoenix Contact 1873443 is RoHS compliant and maintains UL94 V-0 flammability rating, matching the compliance profile of the obsolete part.

Q: What is the inventory status of the substitute?

A: Phoenix Contact 1873443 is an active product with 784 pieces in stock as new original inventory, ensuring reliable procurement availability.
