Weidmüller 1722730000 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1722730000 is a 3-position terminal block plug with female sockets, 0.300" (7.62mm) pitch, designed for 180° free-hanging in-line applications. This component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system maintenance and new design implementations. The part operates within IEC ratings of 16A at 500V and UL ratings of 10A at 300V, with wire gauge compatibility from 12-26 AWG (0.12-2.5mm²).

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1722730000 is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Number of positions: 3
• Pitch: 0.300" (7.62mm)
• Type: Plug with female sockets
• Plug wire entry orientation: 180°
• Mounting type: Free hanging (in-line)
• Wire gauge compatibility: 12-26 AWG minimum overlap

Acceptable Variation Parameters:

• Termination style: Alternative screwless technologies (spring cage, push-in spring) are acceptable if electrical performance is maintained
• Housing material: Alternative polymers acceptable if UL94 V-0 flammability rating is maintained
• Color: Functional variation only
• Wire strip length: Minor variations acceptable within industry standards

Non-Negotiable Parameters:

• Electrical ratings must meet or exceed IEC 16A/500V or UL 10A/300V requirements
• Flammability rating must maintain UL94 V-0 compliance
• Connector geometry must ensure mechanical compatibility with mating headers

The Phoenix Contact 1939646 qualifies as a substitute based on matching critical parameters while maintaining electrical and safety compliance.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1939646 is a qualified substitute for the obsolete Weidmüller 1722730000 based on the following engineering criteria:

Electrical Compatibility: Both components meet UL ratings of 10A at 300V. The Phoenix Contact part exceeds IEC voltage rating at 1 kV compared to the Weidmüller's 500V, while the Weidmüller exceeds IEC current rating at 16A compared to Phoenix Contact's 12A. For applications operating within UL parameters, both are electrically equivalent.

Mechanical Compatibility: Identical pitch (7.62mm), position count (3), wire entry angle (180°), and mounting type (free hanging in-line) ensure direct mechanical substitution without redesign.

Safety Compliance: Both components maintain UL94 V-0 flammability rating and are REACH unaffected, satisfying regulatory requirements.

Product Status Advantage: The Phoenix Contact 1939646 is active production status, ensuring long-term availability and supply chain reliability compared to the obsolete Weidmüller part.

Termination Technology Difference: The Weidmüller uses spring cage tension clamp termination, while Phoenix Contact uses push-in spring termination. Both are screwless technologies; selection depends on wire insertion force preferences and application requirements.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1939646 directly replace the Weidmüller 1722730000 without PCB or header modifications?

A: Yes. Both components share identical pitch (7.62mm), position count (3), and mechanical envelope for free-hanging in-line mounting. Direct substitution is possible without design changes.

Q: What is the significance of the different termination styles (spring cage vs. push-in spring)?

A: Both are screwless termination methods. Spring cage tension clamp (Weidmüller) and push-in spring (Phoenix Contact) differ in wire insertion mechanics. Selection depends on application-specific wire handling requirements and operator preference.

Q: Does the Phoenix Contact part meet the electrical requirements of the original Weidmüller specification?

A: For UL-rated applications, yes. Both meet 10A at 300V. For IEC-rated applications, the Phoenix Contact 1939646 meets 12A at 1 kV, which is lower current but higher voltage than the Weidmüller's 16A at 500V. Application voltage and current requirements determine suitability.

Q: Are there wire gauge compatibility differences between the two parts?

A: Both accept 12-26 AWG wire. The Weidmüller supports 0.12-2.5mm², while Phoenix Contact supports 0.2-2.5mm². The Phoenix Contact has a slightly higher minimum wire gauge (0.2mm² vs. 0.12mm²).

Q: What is the impact of product status (obsolete vs. active)?

A: The Weidmüller 1722730000 is obsolete, meaning manufacturing has ceased and inventory is limited. The Phoenix Contact 1939646 is active production, ensuring ongoing availability, consistent quality, and supply chain reliability for future procurement.

Q: Are retention latches present on both components?

A: Yes. Both the Weidmüller 1722730000 and Phoenix Contact 1939646 feature retention latches on the non-wire side, providing mechanical security for the mated connection.
