Weidmüller 995039 Terminal Block: Equivalent & Substitute Parts

Part Overview

The Weidmüller 995039 is a 20-position wire-to-board terminal block with 5.00mm pitch, designed for horizontal mounting through PCB holes. This component belongs to the Omnimate LP series and features screw-clamping wire termination with side interlocking. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 995039 is determined by the following critical parameters:

• Position count and pitch: Must be 20 positions at 0.197" (5.00mm) spacing
• Mounting configuration: Through-hole PCB mounting with horizontal board orientation
• Electrical ratings: Minimum 300 V voltage rating; current rating of 14.6 A or higher
• Wire termination method: Screw-based clamping mechanism (clamping yoke or rising cage clamp acceptable)
• Housing material: Polyamide (PA66) or equivalent thermoplastic
• Mechanical interface: M3 screw thread; side interlocking feature

The TE Connectivity AMP Connectors part 2-282836-1 meets these substitution criteria across all critical parameters, despite differences in wire gauge range, current rating specification, and clamp material composition.

Engineering Selection Recommendations

The TE Connectivity 2-282836-1 serves as a direct functional substitute for the Weidmüller 995039 based on matching mechanical and electrical specifications. Key considerations for selection:

Product Status: The Weidmüller 995039 is obsolete; the TE Connectivity part maintains active production status, ensuring long-term availability and supply chain continuity.

Compliance: The TE Connectivity substitute is RoHS Compliant and REACH Affected, providing regulatory alignment for applications subject to environmental directives. The original Weidmüller part carries "Not applicable" status for both designations due to its obsolete classification.

Electrical Performance: Both components support 300 V operation. The TE Connectivity part is rated at 14.6 A versus the Weidmüller's 15 A specification. Applications operating below 14.6 A require no derating; higher-current applications must be evaluated against actual load requirements.

Wire Gauge Compatibility: The TE Connectivity part accommodates 16-30 AWG wire, compared to the Weidmüller's 12-26 AWG range. Wire gauges 16-26 AWG are supported by both components; applications using 12-15 AWG or 27-30 AWG wire require alternative solutions.

Termination Mechanism: Both employ M3 screw-based clamping. The Weidmüller uses a clamping yoke with tension sleeve; the TE Connectivity uses a rising cage clamp. Both methods provide equivalent mechanical retention and electrical contact.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 2-282836-1 directly replace the Weidmüller 995039 in existing designs?

A: Yes, for applications operating at 14.6 A or below with wire gauges between 16-26 AWG. The 5.00mm pitch, 20-position configuration, through-hole mounting, and M3 screw termination are identical. PCB footprints are compatible.

Q: What is the impact of the lower current rating on the TE Connectivity substitute?

A: The TE Connectivity part is rated at 14.6 A versus the Weidmüller's 15 A. Applications drawing 14.6 A or less experience no performance change. Applications requiring 15 A operation must either accept the lower rating or source alternative components.

Q: Are the different wire termination methods (clamping yoke vs. rising cage clamp) functionally equivalent?

A: Both methods provide screw-based wire clamping with M3 threads and equivalent mechanical retention. The clamping yoke uses a tension sleeve; the rising cage clamp uses a spring mechanism. Both achieve the same electrical contact and mechanical security.

Q: Does the wire gauge range difference affect substitution?

A: The TE Connectivity part supports 16-30 AWG; the Weidmüller supports 12-26 AWG. Wire gauges 16-26 AWG are compatible with both. Applications using 12-15 AWG wire require the original Weidmüller specification or alternative components rated for smaller gauges.

Q: What are the compliance implications of switching to the TE Connectivity part?

A: The TE Connectivity substitute is RoHS Compliant and REACH Affected, providing regulatory alignment for applications subject to EU environmental directives. The obsolete Weidmüller part carries "Not applicable" status. New designs should specify the TE Connectivity part for regulatory compliance.

Q: Is the Buchanan series (TE Connectivity) mechanically compatible with the Omnimate LP series (Weidmüller) on the same PCB?

A: Yes. Both use identical 5.00mm pitch, 20-position through-hole mounting with M3 screw threads and side interlocking. PCB hole patterns and mounting footprints are interchangeable.

Q: What inventory considerations apply to this substitution?

A: The Weidmüller 995039 is obsolete with limited remaining stock (1026 pcs reported). The TE Connectivity 2-282836-1 is active production with current availability (794 pcs reported). New procurements should specify the TE Connectivity part for supply chain reliability.
