Part Overview

The Weidmüller 1637620000 is a 6-position terminal block plug with female sockets, 0.197" (5.00mm) pitch, and 270° wire entry orientation. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new designs. The part features screw-clamping termination, free-hanging mounting, and is rated for 15A (IEC) / 10A (UL) operation at 400V (IEC) / 300V (UL).

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters: number of positions (6), pitch spacing (5.00mm nominal), plug wire entry angle, termination method (screw-based), mounting configuration (free-hanging), and electrical ratings (current and voltage capacity).

Direct Substitute (Weidmüller 1958830000): This part maintains identical position count, pitch, wire entry angle (270°), termination style, and mounting type. Electrical ratings are enhanced (23A IEC / 20A UL), supporting a broader wire gauge range (12-30 AWG / 0.2-4mm²). Product status is active, and compliance certifications are current.

Similar Substitute (On Shore Technology OSTVM065551): This part shares the 6-position configuration and free-hanging mounting but differs in pitch (5.08mm vs. 5.00mm), wire entry angle (180° vs. 270°), and termination method (pressure clip vs. clamping yoke). Wire gauge compatibility is narrower (12-22 AWG). These differences require mechanical and electrical verification before deployment.

Engineering Selection Recommendations

Weidmüller 1958830000 is the primary substitute for the obsolete 1637620000. Both parts are manufactured by Weidmüller, share identical mechanical and electrical interfaces (pitch, wire entry angle, termination method), and maintain the same operating temperature range. The 1958830000 offers enhanced current ratings (23A IEC / 20A UL) and extended wire gauge compatibility (12-30 AWG / 0.2-4mm²), making it suitable for applications requiring the original part's specifications or higher capacity. Product status is active with current RoHS compliance certification.

On Shore Technology OSTVM065551 is a secondary option for applications where pitch tolerance (5.08mm vs. 5.00mm) and wire entry angle variation (180° vs. 270°) are acceptable. This part supports UL ratings equivalent to the 1958830000 (20A / 300V) but operates within a narrower wire gauge range (12-22 AWG). The ROHS3 compliance status and active product status support long-term availability. Mechanical compatibility with existing connector housings and PCB layouts must be confirmed before selection.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1958830000 directly replace the 1637620000 in existing designs?

A: Yes. Both parts maintain identical pitch (5.00mm), wire entry angle (270°), termination method (screw-clamping yoke), and mounting configuration (free-hanging). The 1958830000 provides equal or superior electrical performance (23A IEC vs. 15A IEC) and broader wire gauge support (12-30 AWG vs. 12-26 AWG). No mechanical or electrical redesign is required.

Q: What are the key differences between the Weidmüller 1958830000 and On Shore OSTVM065551?

A: The primary differences are pitch (5.00mm vs. 5.08mm), wire entry angle (270° vs. 180°), and termination method (clamping yoke vs. pressure clip). The OSTVM065551 also has a narrower wire gauge range (12-22 AWG). These differences may affect mechanical fit and connector compatibility. Verification with existing mating connectors is required.

Q: Is the On Shore OSTVM065551 suitable for IEC-rated applications?

A: The OSTVM065551 does not provide IEC current or voltage ratings. Only UL ratings are specified (20A / 300V). Applications requiring IEC compliance should use the Weidmüller 1958830000, which maintains full IEC ratings (23A / 400V).

Q: What is the wire gauge compatibility for each part?

A: The 1637620000 supports 12-26 AWG (0.5-2.5mm²). The 1958830000 supports 12-30 AWG (0.2-4mm²), offering broader compatibility. The OSTVM065551 supports 12-22 AWG only, which is narrower than both Weidmüller options.

Q: Are all three parts UL94 V-0 rated?

A: Yes. All three parts meet UL94 V-0 material flammability requirements, ensuring equivalent fire safety performance.

Q: What is the product availability status for each part?

A: The 1637620000 is obsolete. The 1958830000 and OSTVM065551 are both active products with current inventory availability, supporting long-term supply chain continuity.
