Weidmüller 995172 Terminal Block: Equivalent & Substitute Parts

Part Overview

The Weidmüller 995172 is a 23-position wire-to-board terminal block with 0.200" (5.08mm) pitch, designed for horizontal mounting through PCB holes. This component features screw-clamping wire termination with side interlocking and operates across -20°C to 100°C. The part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters:

• Position count and pitch: All substitutes must maintain 23 positions at 0.200" (5.08mm) spacing
• Mating orientation and mounting: Horizontal with board orientation and through-hole mounting are mandatory
• Voltage and interlocking features: 300 V rating and side interlocking must be preserved
• Wire gauge compatibility: Acceptable wire gauge ranges must overlap with or exceed 12-26 AWG
• Current rating: Substitutes must meet or exceed 15 A minimum

The identified substitutes meet these core criteria while introducing variations in termination method, temperature range, and compliance status.

Engineering Selection Recommendations

Weidmüller 1330940000 is the primary substitute for direct replacement in active production. This part maintains manufacturer continuity within the Weidmüller product line and is RoHS compliant. The Omnimate LMF series offers improved current capacity (20 A vs. 15 A) and extended operating temperature range (-50°C to 120°C). Wire gauge acceptance is reduced to 12-24 AWG, which excludes 25-26 AWG conductors. Termination transitions from screw-clamping to screwless push-in spring, requiring assembly procedure modification.

Eaton EM250523V provides an alternative from a different manufacturer with active product status. This part preserves the original wire gauge range (12-26 AWG) and screw-based termination methodology, minimizing assembly retraining. Current rating (16 A) exceeds the original specification. Operating temperature range (-40°C to 105°C) covers the original specification with extended lower-temperature capability.

Selection between substitutes depends on assembly process compatibility, wire gauge requirements, and temperature operating envelope for the specific application.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1330940000 accept 25-26 AWG wire? A: No. The 1330940000 accepts 12-24 AWG wire, excluding the 25-26 AWG range supported by the original 995172. Applications requiring 25-26 AWG conductors must use the Eaton EM250523V or maintain the original part.

Q: What is the primary difference in wire termination between these substitutes? A: The original 995172 and Eaton EM250523V use screw-based clamping mechanisms. The Weidmüller 1330940000 uses screwless push-in spring termination, eliminating the need for torque-controlled screw assembly.

Q: Are all three parts mechanically interchangeable on the PCB? A: Yes. All three parts maintain identical 23-position configuration, 0.200" (5.08mm) pitch, horizontal orientation, and through-hole mounting footprint.

Q: Which substitute is recommended for new designs? A: The Weidmüller 1330940000 is recommended for new designs due to active product status and RoHS compliance. The Eaton EM250523V serves as an alternative when wire gauge requirements exceed 24 AWG or when screw-based termination is mandatory.

Q: Do operating temperature ranges affect substitution eligibility? A: Operating temperature ranges do not restrict substitution. Both substitutes exceed or match the original -20°C to 100°C specification. Application requirements determine whether extended temperature capability is necessary.

Q: What is the current rating difference impact? A: The original 995172 is rated 15 A. Both substitutes exceed this: 1330940000 at 20 A and EM250523V at 16 A. Substitutes are suitable for applications designed to the original 15 A specification.
