Weidmüller 1753820000 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1753820000 is a 3-position wire-to-board terminal block with vertical mounting and 0.200" (5.08mm) pitch spacing. This component belongs to the Omnimate LP series and is classified as obsolete. The part features screw-clamping wire termination with a rated current of 20 A and voltage of 300 V, designed for through-hole PCB mounting applications. Due to its obsolete status, identifying functionally equivalent active alternatives is essential for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1753820000 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility: Current rating (20 A), voltage rating (300 V), and wire gauge acceptance (12-26 AWG) must be identical
Mechanical Compatibility: Pitch spacing (0.200" / 5.08mm), mating orientation (vertical with board), and mounting type (through hole) must match exactly
Termination Method: Wire termination approach (screw-clamping yoke with tension sleeve) and screw specifications (M3 thread, 0.5-0.6 Nm torque) must be identical
Physical Form Factor: Position count (3 positions per level) and interlocking feature (side interlocking) must be preserved

The Weidmüller 1994260000 meets all substitution criteria. This part is from the active Omnimate LL series and maintains full electrical and mechanical compatibility with the obsolete 1753820000.
