Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1981746 is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: 2-position plug with male pins
• Pitch Specification: 0.200" (5.08mm) center-to-center spacing
• Wire Entry Orientation: 180° free-hanging in-line configuration
• Termination Method: Screwless push-in spring mechanism
• Electrical Ratings: IEC 12A/630V and UL 10A/300V compliance
• Wire Compatibility: 12-26 AWG (0.2-2.5mm²) acceptance range
• Physical Dimensions: Insulation height 0.591" (15.00mm), wire strip length 10mm
• Material & Compliance: Polyamide housing, UL94 V-0 flammability rating, RoHS compliance

The substitute part Phoenix Contact 1873359 maintains identical electrical, mechanical, and dimensional specifications across all critical parameters, with the distinction that it carries active product status and ROHS3 compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1873359 is the direct functional equivalent to the obsolete 1981746. Both components share identical electrical ratings, mechanical dimensions, termination methodology, and material specifications. The primary distinction is product lifecycle status: 1981746 is obsolete while 1873359 maintains active production status.

For new designs and ongoing procurement, the 1873359 is the appropriate selection. Both parts comply with RoHS directives, with 1873359 carrying the more current ROHS3 certification. The series designation differs slightly (COMBICON FKIC versus COMBICON FKICS), reflecting manufacturing evolution within the same product family while maintaining full electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Are the 1981746 and 1873359 mechanically interchangeable?

A: Yes. Both components feature identical 2-position configuration, 0.200" (5.08mm) pitch, 180° wire entry orientation, and free-hanging in-line mounting. Physical dimensions, including insulation height and wire strip length, are identical.

Q: Do these parts have the same electrical ratings?

A: Yes. Both support IEC ratings of 12A at 630V and UL ratings of 10A at 300V. Wire gauge acceptance ranges from 12-26 AWG (0.2-2.5mm²) for both components.

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

A: The series designation reflects product family evolution. Both designations represent the same functional terminal block plug within the COMBICON product line. The difference does not affect electrical or mechanical compatibility.

Q: Why is the 1981746 listed as obsolete?

A: Product obsolescence reflects manufacturing lifecycle decisions by Phoenix Contact. The 1873359 represents the current active equivalent and is the recommended selection for all applications.

Q: Are there packaging differences between these parts?

A: The 1981746 is listed with unspecified packaging, while the 1873359 is supplied in bulk packaging. Both are identical components; packaging format is the only distinction.

Q: Do both parts meet current compliance standards?

A: Both components are RoHS compliant. The 1873359 carries ROHS3 certification, representing the current regulatory standard. Both maintain EAR99 export classification and identical HTSUS codes.
