Weidmüller 995029 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Weidmüller 995029 is a 10-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 side-entry interlocking capability with screw-clamping wire termination. The part is currently obsolete, making identification of compatible substitute components essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 995029 is determined by the following critical parameters:

Position Count & Pitch: Must maintain 10 positions at 0.197" (5.00mm) pitch for PCB footprint compatibility
Mating Orientation: Must be horizontal with board configuration for mounting alignment
Mounting Type: Must support through-hole PCB mounting
Electrical Ratings: Substitute must meet or exceed 300 V voltage and 15 A current requirements
Wire Termination Method: Screw-based termination is required for mechanical compatibility
Screw Thread: M3 thread specification for assembly consistency
Housing Material: Polyamide (PA66) construction for thermal and mechanical properties
Interlocking Feature: Side-entry interlocking capability for connector security

The TE Connectivity AMP Connectors part 1-796683-0 satisfies all critical substitution parameters while offering enhanced electrical performance and active product status.

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 1-796683-0 (Buchanan series) is the qualified substitute for the obsolete Weidmüller 995029. Selection rationale is based on:

Functional Equivalence: All critical mechanical and electrical parameters align with or exceed the original specification
Active Product Status: The substitute maintains active manufacturing status, ensuring long-term availability and supply chain continuity
Regulatory Compliance: ROHS3 compliance and REACH regulation adherence provide superior environmental and safety certification compared to the obsolete original
Enhanced Performance: Higher current rating (17.5 A vs. 15 A) and expanded wire gauge range (12-30 AWG vs. 12-26 AWG) provide design flexibility
Mechanical Compatibility: Identical pitch, position count, mounting type, and screw thread ensure direct PCB footprint compatibility

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-796683-0 be used as a direct replacement for the Weidmüller 995029?

A: Yes. Both components share identical pitch (5.00mm), position count (10), mating orientation (horizontal with board), mounting type (through hole), and screw thread (M3). PCB footprints are compatible. The substitute meets or exceeds all electrical ratings.

Q: What is the difference in wire termination between these two parts?

A: The Weidmüller 995029 uses a clamping yoke with tension sleeve termination method, while the TE Connectivity 1-796683-0 uses a rising cage clamp. Both are screw-based termination systems that provide equivalent mechanical wire retention and electrical contact performance.

Q: Does the higher current rating of the substitute affect compatibility?

A: No. The TE Connectivity part's 17.5 A rating exceeds the original 15 A specification, making it suitable for applications requiring the original current capacity. The higher rating does not introduce incompatibility.

Q: Are there packaging differences between these components?

A: The Weidmüller 995029 is listed with unspecified packaging, while the TE Connectivity 1-796683-0 is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: What compliance advantages does the substitute offer?

A: The TE Connectivity 1-796683-0 is ROHS3 compliant and REACH affected, providing current environmental regulation adherence. The original Weidmüller part carries obsolete status with no applicable RoHS or REACH designation.

Q: Is the wire gauge range difference significant?

A: The substitute accepts 12-30 AWG wire, compared to the original 12-26 AWG. This expanded range provides additional design flexibility for applications requiring larger gauge conductors within the same connector footprint.
