Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 995043 is determined by the following critical parameters:

• 24-position configuration with 5mm pitch spacing
• Horizontal with board mating orientation
• Through-hole PCB mounting
• Minimum 15A current capacity at 300V
• Wire gauge accommodation of 12-26 AWG range
• Side interlocking feature
• Screw-based wire termination method

The identified substitute parts meet these core electrical and mechanical requirements while maintaining functional compatibility in equivalent applications.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 995043 is classified as obsolete, necessitating transition to active substitute components. Both TE Connectivity 2-1986711-4 and Eaton EM258524V are active products meeting the core electrical and mechanical specifications.

TE Connectivity 2-1986711-4 provides ROHS3 compliance and extended operating temperature range (-40°C to 110°C). This part utilizes screwless push-button clamping termination, differing from the original screw-clamping design. Wire gauge accommodation extends to 30 AWG.

Eaton EM258524V maintains screw-based termination methodology consistent with the original design, utilizing a rising cage clamp configuration. Operating temperature range extends to -40°C to 105°C. Contact material is brass with tin plating rather than copper alloy.

Selection between substitutes depends on termination method preference and compliance requirements for the target application.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 2-1986711-4 directly replace the Weidmüller 995043?

A: Functional replacement is possible. The TE part meets all core electrical and mechanical parameters. However, the termination method differs: TE uses screwless push-button clamping versus the original screw-clamping design. PCB layout and assembly procedures may require adjustment.

Q: What is the primary difference between the two substitute parts?

A: Wire termination methodology differs. TE Connectivity 2-1986711-4 uses screwless push-button clamping, while Eaton EM258524V uses screw-based rising cage clamping. The Eaton part more closely mirrors the original screw-termination approach.

Q: Are both substitute parts RoHS compliant?

A: TE Connectivity 2-1986711-4 is ROHS3 compliant. Eaton EM258524V compliance status is not specified in available documentation.

Q: Do the substitute parts accommodate the same wire gauge range?

A: The Weidmüller 995043 and Eaton EM258524V both accommodate 12-26 AWG. TE Connectivity 2-1986711-4 extends to 12-30 AWG, providing broader wire gauge compatibility.

Q: What are the current and voltage ratings for the substitute parts?

A: Both substitute parts are rated for 16A at 300V, exceeding the original 15A specification. This provides improved current capacity margin.

Q: How do operating temperature ranges compare?

A: The original Weidmüller part operates from -20°C to 100°C. Both substitutes extend the lower temperature limit to -40°C. TE Connectivity reaches 110°C maximum; Eaton reaches 105°C maximum.
