Weidmüller 1561810000 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1561810000 is a 24-position terminal block plug with female sockets, 0.200" (5.08mm) pitch, and 270° free-hanging wire entry configuration. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations. The part operates within IEC ratings of 15A at 400V and UL ratings of 10A at 300V, with wire gauge compatibility from 12-26 AWG (0.2-2.5mm²).

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Weidmüller 1561810000 is determined by the following critical parameters:

• Position Count & Pitch: Both main and substitute parts must maintain 24 positions at 0.200" (5.08mm) pitch to ensure mechanical and electrical compatibility with mating connectors.
• Connector Type: Female socket plugs with free-hanging (in-line) mounting configuration.
• Electrical Ratings: Substitute parts must meet or exceed the operational voltage and current requirements. The Weidmüller part operates at IEC 15A/400V and UL 10A/300V.
• Wire Gauge Compatibility: Wire termination range must accommodate the 12-26 AWG (0.2-2.5mm²) specification.
• Termination Method: Screw-based clamping systems are functionally equivalent for this application category.
• Regulatory Compliance: UL94 V-0 flammability rating and REACH compliance status.

The On Shore Technology Inc. OSTVM245551 qualifies as a substitute based on matching position count, pitch, connector type, mounting configuration, and regulatory compliance. Differences in wire entry angle (180° vs. 270°), termination mechanism (pressure clip vs. clamping yoke), and electrical ratings are noted in the parameter comparison.

Parameter Comparison

Engineering Selection Recommendations

The On Shore Technology Inc. OSTVM245551 is an active product suitable for substitution in applications currently using the obsolete Weidmüller 1561810000. Both components maintain UL94 V-0 flammability compliance and REACH unaffected status, meeting regulatory requirements for industrial terminal block applications.

The OSTVM245551 provides higher UL current rating (20A vs. 10A), which represents improved electrical capacity. However, the wire gauge range is narrower (12-22 AWG vs. 12-26 AWG), requiring verification that existing wire sizes fall within the acceptable range. The 180° wire entry angle differs from the original 270° configuration, necessitating mechanical layout assessment for physical installation compatibility.

Both components employ screw-based termination with retention latches on the non-wire side. The pressure clip termination method of the OSTVM245551 differs from the clamping yoke mechanism of the Weidmüller part, though both are standard screw-termination approaches in this product category.

Frequently Asked Questions (FAQ)

Q: Can the On Shore OSTVM245551 directly replace the Weidmüller 1561810000 in existing installations?

A: Direct replacement requires verification of two factors: wire gauge compatibility (the OSTVM245551 accepts 12-22 AWG, while the original accepts 12-26 AWG) and physical space for the 180° wire entry angle versus the original 270° configuration. Electrical ratings are compatible, with the substitute providing higher current capacity.

Q: What is the significance of the different wire entry angles (270° vs. 180°)?

A: Wire entry angle determines the physical orientation of the connector relative to the circuit board or mounting surface. A 270° entry allows wire approach from the rear, while 180° entry allows approach from the side. Installation feasibility depends on available space and existing wiring harness routing in the application.

Q: Are the termination methods functionally equivalent?

A: Both components use screw-based termination with retention latches. The Weidmüller uses a clamping yoke (tension sleeve) mechanism, while the On Shore uses a pressure clip approach. Both methods provide secure wire retention and are standard in industrial terminal block applications. Torque specifications differ slightly (0.4-0.5 Nm vs. 0.4 Nm), both within acceptable ranges for this connector class.

Q: What wire gauge range should be used for the substitute part?

A: The On Shore OSTVM245551 accepts 12-22 AWG wire. If the original installation uses 24-26 AWG wire, the substitute cannot accommodate these sizes. Verify all wire gauges in the application fall within the 12-22 AWG range before substitution.

Q: Are there compliance differences between the two parts?

A: Both parts maintain UL94 V-0 flammability rating and REACH unaffected status. The Weidmüller part is obsolete, while the On Shore part is active. Active product status ensures ongoing availability and support for future procurement.
