Weidmüller 995157 Terminal Block: Equivalent & Substitute Parts

Part Overview

The Weidmüller 995157 is an 8-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 identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where this series is no longer available.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 995157 is determined by the following critical parameters:

• Pitch and Position Count: Must maintain 0.200" (5.08mm) pitch with 8 positions per level to ensure PCB footprint compatibility
• Mating Orientation: Must be horizontal with board configuration for mounting alignment
• Current and Voltage Ratings: Must meet or exceed 15 A and 300 V specifications
• Wire Gauge Compatibility: Must accommodate the 12-26 AWG wire range or a subset thereof
• Mounting Type: Must be through-hole to match existing PCB design
• Wire Termination Method: Screw-based clamping systems are functionally equivalent
• Interlocking Feature: Side interlocking must be present for mechanical stability

Two substitute parts meet these criteria: Weidmüller 9993960000 and Eaton EM250508V. Both maintain the core electrical and mechanical specifications while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Weidmüller 9993960000 is the primary substitute for direct replacement in existing designs. This part maintains identical electrical ratings (15 A, 300 V) and pitch specifications while offering active product status and RoHS compliance. The wire gauge range (14-24 AWG) is narrower than the original but covers standard industrial applications. The extended operating temperature range (-50°C to 120°C) provides improved thermal performance. Note that the screw thread is M2.5 rather than M3, requiring torque adjustment to 0.4-0.5 Nm (4.6-4.4 Lb-In).

Eaton EM250508V serves as an alternative substitute with slightly higher current capacity (16 A) and maintains the original M3 screw thread specification. This part supports the full 12-26 AWG wire gauge range and offers ROHS3 compliance. The rising cage clamp termination method differs from the original clamping yoke design but provides equivalent screw-based wire retention. Operating temperature range is -40°C to 105°C.

Selection between substitutes depends on wire gauge requirements and thermal operating conditions. Applications requiring 12 AWG wire support should specify Eaton EM250508V. Systems operating below -40°C or above 105°C should specify Weidmüller 9993960000.

Frequently Asked Questions (FAQ)

Q: Can Weidmüller 9993960000 replace Weidmüller 995157 in existing PCB designs?

A: Yes. Both parts share identical pitch (5.08mm), position count (8), and mating orientation (horizontal with board). PCB footprints are compatible. The M2.5 screw thread requires torque adjustment from 0.5-0.6 Nm to 0.4-0.5 Nm during installation.

Q: What is the wire gauge limitation when using Weidmüller 9993960000?

A: Weidmüller 9993960000 accepts 14-24 AWG wire. The original 995157 supports 12-26 AWG. If your application requires 12 AWG or 26 AWG wire, use Eaton EM250508V instead.

Q: Are the screw termination methods interchangeable between these parts?

A: Both Weidmüller 9993960000 and Eaton EM250508V use screw-based clamping systems. Weidmüller 9993960000 uses clamping yoke with tension sleeve; Eaton EM250508V uses rising cage clamp. Both methods provide equivalent wire retention and are functionally interchangeable from an electrical standpoint.

Q: Which substitute offers the widest operating temperature range?

A: Weidmüller 9993960000 operates from -50°C to 120°C, providing the widest thermal envelope. Eaton EM250508V operates from -40°C to 105°C. Select based on your system's thermal requirements.

Q: Do both substitutes meet RoHS compliance requirements?

A: Yes. Weidmüller 9993960000 is RoHS Compliant. Eaton EM250508V is ROHS3 Compliant. The original 995157 has RoHS status listed as not applicable due to its obsolete classification.

Q: Is the M3 screw thread preserved in both substitutes?

A: Weidmüller 9993960000 uses M2.5 thread; Eaton EM250508V uses M3 thread. If your assembly process is optimized for M3 fasteners, specify Eaton EM250508V to minimize tooling changes.
