Weidmüller 995156 Terminal Block: Equivalent & Substitute Parts

Part Overview

The Weidmüller 995156 is a 7-position wire-to-board terminal block with 0.200" (5.08mm) pitch, designed for horizontal mounting through PCB holes. This component features side entry interlocking, screw-clamping wire termination, and operates across -20°C to 100°C. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications requiring compatible 7-position, 5.08mm pitch terminal block solutions.

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 995156 is determined by the following core parameters:

Positions and Pitch: All substitutes must maintain 7 positions per level with 0.200" (5.08mm) pitch to ensure PCB footprint compatibility
Mating Orientation: Horizontal with board configuration is required for mechanical fit
Mounting Type: Through-hole mounting is mandatory for PCB integration
Voltage Rating: 300 V minimum rating ensures electrical compatibility
Side Entry Interlocking: This mechanical feature must be present for proper assembly and retention

The identified substitutes meet these core criteria. Variations in current rating, wire gauge range, wire termination method, temperature range, and compliance status represent secondary differences that do not prevent functional substitution within the specified electrical and mechanical envelope.

Engineering Selection Recommendations

Weidmüller 1330770000 is the primary substitute for the 995156. Both components are manufactured by Weidmüller within the Omnimate series. The 1330770000 is active in production status, RoHS compliant, and provides enhanced current capacity (20 A versus 15 A) and extended temperature range (-50°C to 120°C). The wire termination method differs (screwless push-in spring versus screw-clamping), which may require assembly procedure modification but does not affect electrical or mechanical compatibility. Wire gauge compatibility is maintained within the 12-24 AWG range.

Eaton EM250507V serves as a secondary substitute. This component maintains identical pitch, position count, and voltage rating. Current rating (16 A) and operating temperature range (-40°C to 105°C) are comparable to the original part. The screw-based termination method aligns with the 995156 design approach. RoHS non-compliance status should be evaluated against application requirements. Contact material differs (brass versus copper alloy), and screw torque specification is higher (0.79 Nm versus 0.5-0.6 Nm).

Selection between substitutes depends on compliance requirements, assembly process compatibility with termination method changes, and temperature operating envelope needs.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1330770000 replace the 995156 in existing PCB designs?

A: Yes. Both components share identical pitch (5.08mm), position count (7), mating orientation (horizontal with board), and mounting type (through-hole). PCB footprints are compatible. Wire termination method differs, requiring assembly procedure adjustment from screw-clamping to push-in spring operation.

Q: What is the primary difference between screw-clamping and screwless push-in termination?

A: Screw-clamping (995156, EM250507V) requires manual torque application during assembly. Screwless push-in (1330770000) uses spring-loaded mechanisms for wire retention without torque specification. Both methods provide equivalent electrical connection reliability within their respective design parameters.

Q: Is the Eaton EM250507V suitable for applications requiring RoHS compliance?

A: No. The EM250507V is RoHS non-compliant. The Weidmüller 1330770000 is RoHS compliant and should be selected for applications with RoHS requirements.

Q: Does the higher current rating of the 1330770000 (20 A) affect compatibility?

A: No. Higher current rating indicates enhanced capacity and does not prevent substitution in applications rated at 15 A or lower. The component remains electrically compatible.

Q: Are wire gauge ranges compatible across all three parts?

A: The 995156 and EM250507V both accept 12-26 AWG wire. The 1330770000 accepts 12-24 AWG wire. For wire gauges 25-26 AWG, only the 995156 or EM250507V are suitable. For 12-24 AWG applications, all three parts are compatible.

Q: What temperature range should be considered for substitute selection?

A: The 995156 operates -20°C to 100°C. The 1330770000 extends this to -50°C to 120°C, and the EM250507V covers -40°C to 105°C. Select based on application temperature requirements. All three parts exceed the original specification range or match it.
