Weidmüller 1636950000 Terminal Block Plug — Equivalent & Substitute Parts

Part Overview

The Weidmüller 1636950000 is an 8-position terminal block plug with female sockets, 5.00mm pitch, and 90° wire entry orientation. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new designs. The part operates within IEC ratings of 15A at 400V and UL ratings of 10A at 300V, with wire gauge compatibility from 12–26 AWG (0.5–2.5mm²).

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Number of Positions & Pitch: All substitute parts must provide 8 positions. Pitch tolerance is limited to 5.00mm (0.197") and 5.08mm (0.200"), as these are mechanically compatible within standard connector mating tolerances.
• Wire Entry Orientation: The main part specifies 90° wire entry. Substitute parts with 180° (straight) wire entry represent a functional alternative for applications where wire routing differs, but this constitutes a design change.
• Termination Style: Screw-based termination is mandatory. Variations in clamping mechanism (Clamping Yoke vs. Rising Cage Clamp vs. Pressure Clip) are acceptable provided screw-based connection is maintained.
• Electrical Ratings: Substitute parts must meet or exceed the main part's IEC and UL current and voltage specifications, or be suitable for the intended application's actual load requirements.
• Wire Gauge Compatibility: Wire gauge range must overlap with or exceed the main part's 12–26 AWG (0.5–2.5mm²) specification.
• Flammability & Compliance: All substitute parts must maintain UL94 V-0 rating and RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Direct Replacement): Weidmüller 1958590000 is the preferred substitute. It maintains identical pitch (5.00mm), wire entry orientation (90°), and termination mechanism (Screw - Clamping Yoke). The part is active in production, RoHS compliant, and offers enhanced electrical ratings (20A UL vs. 10A UL) and expanded wire gauge compatibility (12–30 AWG vs. 12–26 AWG). No design modification is required.

Secondary Substitutes (Design Consideration Required): TE Connectivity 284046-8 provides 90° wire entry and 5.00mm pitch compatibility but uses a Rising Cage Clamp termination mechanism and M3 screw size instead of M2.5. This part is suitable for applications where the termination mechanism change is acceptable. Operating temperature range extends to +110°C.

On Shore Technology OSTVM085551 and OSTVM085581 feature 180° (straight) wire entry, representing a functional alternative for applications with different wire routing requirements. Pitch is 5.08mm (0.200"), which is mechanically compatible within standard tolerances. Wire gauge range is narrower (12–22 AWG). These parts are active and ROHS3 compliant.

Compliance Considerations: All substitute parts maintain UL94 V-0 flammability rating and RoHS compliance. TE Connectivity 284046-8 is REACH Affected; Weidmüller 1958590000 and On Shore parts are REACH Unaffected.

Frequently Asked Questions (FAQ)

Q: Can Weidmüller 1958590000 be used as a direct replacement for 1636950000? A: Yes. Both parts share identical pitch (5.00mm), wire entry orientation (90°), and termination style (Screw - Clamping Yoke). The 1958590000 is active in production and offers improved electrical ratings and wire gauge range.

Q: What is the difference between 90° and 180° wire entry? A: 90° wire entry (right-angle) is suitable for applications where wires approach the connector from the side. 180° wire entry (straight/in-line) is used when wires approach from the rear. This is a mechanical design consideration and requires verification against your application's wire routing.

Q: Are the On Shore Technology parts (OSTVM085551 and OSTVM085581) compatible? A: These parts are mechanically compatible within standard connector tolerances due to the 5.08mm pitch being within acceptable mating tolerance of 5.00mm. However, they feature 180° wire entry instead of 90°, requiring design verification. Wire gauge range is also narrower (12–22 AWG vs. 12–26 AWG).

Q: What is the difference between OSTVM085551 and OSTVM085581? A: Both parts are electrically and mechanically identical. The primary difference is housing color: OSTVM085551 is green, and OSTVM085581 is gray. Selection depends on application-specific color coding requirements.

Q: Does TE Connectivity 284046-8 require any design changes? A: The 284046-8 uses M3 screw size instead of M2.5 and employs a Rising Cage Clamp termination mechanism instead of Clamping Yoke. Verify that your application's PCB or connector housing accommodates M3 screws and that the termination mechanism is compatible with your wire termination process.

Q: Are all substitute parts RoHS compliant? A: Yes. Weidmüller 1958590000 is RoHS Compliant. TE Connectivity 284046-8 is RoHS Compliant. On Shore Technology OSTVM085551 and OSTVM085581 are ROHS3 Compliant. All meet current RoHS requirements.

Q: What is the wire gauge compatibility range for each part? A: 1636950000 and 1958590000 support 12–26 AWG (0.5–2.5mm²). TE Connectivity 284046-8 supports 12–30 AWG (0.05–3mm²). On Shore OSTVM085551 and OSTVM085581 support 12–22 AWG. Verify your application's wire gauge falls within the selected part's range.
