Weidmüller 995018 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Weidmüller 995018 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 995018 is determined by the following critical parameters:

• Position Count & Pitch: Both main and substitute parts must maintain 20 positions at 0.197" (5.00mm) pitch to ensure PCB footprint compatibility
• Mounting Configuration: Through-hole horizontal orientation with board is mandatory for mechanical fit
• Electrical Ratings: Voltage rating of 300 V is a fixed requirement; current rating variance is acceptable within operational limits
• Wire Termination Method: Screw-based termination is required; however, specific clamping mechanism variations (clamping yoke vs. rising cage clamp) are functionally equivalent for wire retention
• Housing Material: Polyamide (PA66) construction ensures thermal and mechanical compatibility
• Screw Thread: M3 thread specification must be maintained for assembly consistency

The TE Connectivity AMP Connectors part 2-282836-1 meets these substitution criteria with the following considerations: reduced current capacity (14.6 A vs. 15 A), expanded wire gauge range (16-30 AWG vs. 12-26 AWG), and alternative clamping mechanism (rising cage clamp). These variations remain within acceptable substitution parameters for equivalent functionality.

Engineering Selection Recommendations

The TE Connectivity 2-282836-1 serves as a direct functional substitute for the obsolete Weidmüller 995018 based on matching mechanical and electrical specifications. Key selection factors include:

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

Compliance & Certifications: The TE Connectivity part is RoHS Compliant and REACH Affected, providing regulatory alignment for applications requiring environmental compliance. The Weidmüller part carries "Not applicable" RoHS status due to its obsolete classification.

Electrical Performance: While the TE Connectivity part exhibits reduced current capacity (14.6 A vs. 15 A), this remains suitable for applications operating within the lower current envelope. Designs requiring the full 15 A capacity must verify that the substitute's rating is adequate for the intended circuit.

Wire Gauge Compatibility: The TE Connectivity part accommodates wire gauges 16-30 AWG, which overlaps with the Weidmüller range (12-26 AWG) in the 16-26 AWG band. Applications using 12-14 AWG or 27-30 AWG wires require specific evaluation.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 2-282836-1 directly replace the Weidmüller 995018 on existing PCBs?

A: Yes, both parts share identical pitch (5.00mm), position count (20), and through-hole mounting configuration. PCB footprints are mechanically compatible. Verify that your application's current requirements do not exceed 14.6 A.

Q: What is the difference between clamping yoke and rising cage clamp termination methods?

A: Both are screw-based wire retention mechanisms. The clamping yoke uses tension sleeve compression, while the rising cage clamp uses a different mechanical geometry. Both achieve equivalent wire retention and electrical contact for this application category.

Q: Are there wire gauge restrictions when substituting?

A: The TE Connectivity part accepts 16-30 AWG wire. If your design uses 12-14 AWG conductors, the Weidmüller part's 12-26 AWG range is required. Verify wire gauge compatibility before substitution.

Q: What is the impact of the current rating difference (15 A vs. 14.6 A)?

A: The 1.5 A reduction represents a 10% decrease in maximum current capacity. Applications operating below 14.6 A are unaffected. Designs at or near 15 A must be re-evaluated for thermal and electrical performance with the substitute part.

Q: Does RoHS compliance matter for my application?

A: RoHS compliance is mandatory for products sold in the European Union and many other markets. The TE Connectivity part is RoHS Compliant, while the Weidmüller part is not applicable due to obsolescence. Select based on your regulatory requirements.

Q: Can I use both parts interchangeably in inventory?

A: Both parts are mechanically and electrically compatible for most applications. However, maintain separate inventory tracking due to differences in current rating, wire gauge range, and compliance certifications. Document substitution decisions in your bill of materials.
