Phoenix Contact 1981720 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1981720 is a 15-position terminal block plug with male pins, 5.00mm pitch, designed for free-hanging in-line mounting with 180° wire entry. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing system maintenance and new design implementations. The part features screwless push-in spring termination with tin-plated contacts and UL94 V-0 rated polyamide housing, supporting wire gauges from 12-26 AWG (0.2-2.5mm²).

Substitute Part Grouping Explanation

Substitution compatibility for the Phoenix Contact 1981720 is determined by the following critical parameters:

Connector Type & Configuration: 15-position plug with male pins, 5.00mm pitch
Mounting & Orientation: Free-hanging in-line mounting with 180° wire entry
Electrical Ratings: Minimum 12A current capacity (IEC) and 300V voltage rating (UL)
Termination Method: Screwless push-in spring technology
Wire Compatibility: Support for 12-26 AWG (0.2-2.5mm²) conductors
Housing & Compliance: Polyamide construction with UL94 V-0 flammability rating

The Phoenix Contact 1910953 qualifies as a direct substitute based on matching all critical parameters within the allowed electrical and mechanical specifications for this product category.

Engineering Selection Recommendations

The Phoenix Contact 1910953 is the appropriate substitute for the obsolete 1981720 model. Both components maintain identical mechanical and electrical specifications across all critical parameters, including 15-position configuration, 5.00mm pitch, 180° wire entry, and UL94 V-0 housing compliance.

The primary distinction is product status: the 1981720 is obsolete while the 1910953 is active. This transition represents a standard product line evolution within the COMBICON series, with the 1910953 offering continued manufacturer support, availability, and compliance certification.

The IEC voltage rating differential (630V vs. 320V) does not impact substitution suitability for applications operating within the UL standard of 300V, which both parts equally support. For applications requiring the full 630V IEC rating, component-level voltage verification is necessary.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1910953 directly replace the 1981720 in existing assemblies?

A: Yes. Both components share identical mechanical dimensions, pitch, position count, wire entry angle, and termination methodology. Pin-to-pin compatibility is confirmed across all 15 positions.

Q: What is the significance of the product status change from Obsolete to Active?

A: The 1910953 represents the current production equivalent. Active status ensures ongoing manufacturer support, documented compliance certifications, and supply chain availability. The 1981720 is no longer manufactured.

Q: Are there electrical rating differences that affect substitution?

A: The IEC voltage rating differs (630V vs. 320V). However, both parts meet the UL standard of 300V. Applications operating within 300V specifications experience no functional limitation. Applications requiring 630V IEC compliance must retain the original 1981720 or identify alternative solutions.

Q: Does the termination style difference impact compatibility?

A: The 1981720 lists "Screwless - Leg Spring, Push-In Spring" while the 1910953 specifies "Screwless - Push-In Spring." Both employ push-in spring termination, the primary functional mechanism. This represents a minor design refinement within the same termination family and does not affect wire insertion or retention performance.

Q: What wire gauges are supported by the substitute part?

A: Both the 1981720 and 1910953 accept 12-26 AWG conductors (0.2-2.5mm²) with 10mm strip length. Wire compatibility is identical.

Q: Is the 1910953 RoHS compliant?

A: The 1981720 is explicitly RoHS compliant. The 1910953 RoHS status is not specified in available documentation. For applications with mandatory RoHS requirements, compliance verification with Phoenix Contact is recommended.
