Weidmüller 995042 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Weidmüller 995042 is a 23-position wire-to-board terminal block with 5.00mm pitch, designed for horizontal mounting through PCB holes. This component features side-entry interlocking configuration with screw-clamping wire termination, rated for 15A at 300V, and accommodates wire gauges from 12-26 AWG. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications requiring compatible 23-position terminal block solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 995042 is determined by the following critical parameters:

• Position Count: Must be 23 positions per level
• Pitch Spacing: Must be 0.197" (5.00mm)
• Mating Orientation: Must be horizontal with board
• Mounting Type: Must be through-hole PCB mounting
• Electrical Ratings: Minimum 15A current and 300V voltage capability
• Wire Gauge Compatibility: Must accommodate 12-26 AWG minimum range
• Interlocking Feature: Must include side-entry interlocking

The identified substitutes meet these core requirements while offering improvements in product status (active vs. obsolete), expanded operating temperature ranges, and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 2-1986711-3 is suitable for applications where screwless push-button termination is acceptable and extended operating temperature range (-40°C to 110°C) is beneficial. This part carries ROHS3 compliance and is actively manufactured, ensuring long-term availability. Wire gauge accommodation extends to 30 AWG, providing additional flexibility for smaller conductor applications.

Eaton EM258523V maintains screw-based termination consistent with the original Weidmüller design, utilizing a rising cage clamp mechanism. This part supports the original 12-26 AWG wire gauge range and operates across -40°C to 105°C. Active product status ensures continued supply chain availability.

Both substitutes exceed the original 15A current rating at 16A and maintain 300V voltage specifications. Selection between substitutes depends on termination method preference and specific temperature operating requirements.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 2-1986711-3 directly replace Weidmüller 995042 in existing designs?

A: Direct mechanical and electrical replacement is possible. The primary difference is termination method: TE Connectivity uses screwless push-button clamping versus the original screw-clamping design. PCB footprint and pitch spacing are identical at 5.00mm. Verify that the push-button termination interface is compatible with your assembly process and equipment.

Q: What is the wire gauge compatibility difference between substitutes?

A: Weidmüller 995042 and Eaton EM258523V both support 12-26 AWG. TE Connectivity 2-1986711-3 extends this range to 12-30 AWG, accommodating smaller gauge conductors if required by application specifications.

Q: Are there temperature operating range considerations for substitute selection?

A: The original Weidmüller operates -20°C to 100°C. Both substitutes extend the lower limit to -40°C and upper limits to 110°C (TE Connectivity) or 105°C (Eaton), providing broader environmental tolerance. Select based on your application's thermal requirements.

Q: How do the termination methods differ between substitutes?

A: Weidmüller 995042 uses screw-clamping with tension sleeve. TE Connectivity 2-1986711-3 employs screwless push-button clamping, reducing assembly time. Eaton EM258523V uses screw-based rising cage clamp termination. Choose based on your assembly equipment and process compatibility.

Q: What compliance certifications should I verify for my application?

A: TE Connectivity 2-1986711-3 carries ROHS3 compliance. Verify RoHS, REACH, and any industry-specific certifications required by your end application before final component selection.
