Part Overview

The Weidmüller 1636000000 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 identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. The part features screw-clamping termination, free-hanging mounting, and operates across -50°C to 100°C with IEC ratings of 15A at 400V and UL ratings of 10A at 300V.

Substitute Part Grouping Explanation

Substitution eligibility for the 1636000000 is determined by the following critical parameters:

Primary Compatibility Criteria:

8-position configuration with female sockets
5.00mm pitch (±0.08mm tolerance acceptable for 5.08mm variants)
Screw-based termination mechanism
Free-hanging in-line mounting
Wire gauge compatibility within 12-26 AWG range
Operating temperature range overlap
Material flammability rating UL94 V-0

Substitute Classification:

Direct Equivalent (Weidmüller 1958230000): Active product from same manufacturer, identical series (Omnimate BL), matching pitch, orientation, and termination style. Enhanced current ratings (23A IEC, 20A UL) and expanded wire gauge support (12-30 AWG, 0.2-4mm²) provide superior capability while maintaining mechanical and electrical compatibility.

Similar Alternatives (On Shore Technology OSTVM085551 and OSTVM085581): Same 8-position configuration and pitch (5.08mm), but differ in wire entry orientation (180° vs. 90°), termination mechanism (pressure clip vs. clamping yoke), and contact material (steel vs. copper alloy). These represent functional alternatives for applications where orientation flexibility exists.

Engineering Selection Recommendations

For Direct Replacement (Preferred): Weidmüller 1958230000 is the primary substitute. This part maintains identical mechanical interface, pitch, and wire entry orientation while offering active product status and enhanced electrical ratings. The expanded current capacity (23A IEC, 20A UL) and wire gauge range (0.2-4mm²) provide design margin without requiring PCB or connector modifications. RoHS compliance status is confirmed.

For Orientation-Flexible Applications: On Shore Technology OSTVM085551 or OSTVM085581 are viable alternatives where 180° wire entry orientation is acceptable. These parts maintain 8-position configuration, 5.08mm pitch compatibility, and equivalent electrical ratings. Selection between OSTVM085551 (green) and OSTVM085581 (gray) depends on color-coding requirements. Note that pressure-clip termination differs from the clamping-yoke mechanism of the original part.

Compliance Considerations: All substitute parts carry UL94 V-0 flammability certification. The 1958230000 and On Shore variants are RoHS compliant, addressing modern regulatory requirements absent from the obsolete 1636000000 specification.

Frequently Asked Questions (FAQ)

Q: Can 1958230000 be used as a direct drop-in replacement for 1636000000?

A: Yes. Both parts share identical 8-position configuration, 5.00mm pitch, 90° wire entry, screw-clamping termination, and free-hanging mounting. The 1958230000 is mechanically and electrically compatible with no modifications required. The enhanced current ratings represent improved capability rather than incompatibility.

Q: What is the pitch difference between 5.00mm and 5.08mm, and does it affect compatibility?

A: The 0.08mm difference is within standard manufacturing tolerance for terminal block systems. On Shore Technology parts (OSTVM085551, OSTVM085581) with 5.08mm pitch are mechanically compatible with 5.00mm pitch connectors in most applications. However, verify mating connector specifications for your specific system before implementation.

Q: Why do the On Shore parts have 180° wire entry instead of 90°?

A: Wire entry orientation is determined by the connector's physical design. The 180° orientation on OSTVM parts means wires enter from the opposite direction compared to the 1636000000. This affects PCB layout and wire routing. Use On Shore alternatives only if your application permits this orientation change or if you can accommodate the different wire entry angle.

Q: Are there differences in termination mechanism between these parts?

A: Yes. The 1636000000 and 1958230000 use screw-clamping yoke (tension sleeve) termination. The On Shore OSTVM parts use screw-pressure clip termination. Both are screw-based and secure wires effectively, but the clamping mechanism differs. Verify that your wire gauge and installation procedure are compatible with the pressure-clip design if selecting On Shore alternatives.

Q: What wire gauges are supported by each part?

A: 1636000000 supports 12-26 AWG (0.5-2.5mm²). The 1958230000 expands this to 12-30 AWG (0.2-4mm²), accommodating finer and heavier gauge wires. On Shore OSTVM parts support 12-22 AWG, which is more restrictive. Verify your wire gauge falls within the substitute part's range before selection.

Q: Are all substitute parts RoHS compliant?

A: The 1958230000 is RoHS Compliant. The On Shore OSTVM085551 and OSTVM085581 are ROHS3 Compliant. The original 1636000000 does not specify RoHS status. If RoHS compliance is a system requirement, the 1958230000 or On Shore variants are appropriate choices.

Q: What is the operating temperature range for each part?

A: The 1636000000 and 1958230000 operate from -50°C to 100°C. The On Shore OSTVM parts operate from -30°C to 105°C. If your application requires operation below -30°C, the Weidmüller parts are necessary. For applications above 100°C, the On Shore variants provide extended upper temperature capability.

Q: Can I mix these parts in the same system?

A: Mechanically, yes, provided wire entry orientation and pitch differences are accommodated. Electrically, all parts meet UL94 V-0 flammability and equivalent voltage/current ratings for typical applications. However, verify that your specific system design permits mixing different termination mechanisms and contact materials before implementation.
