Weidmüller 1629200000 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1629200000 is a 9-position vertical terminal block header with male pins and 4-side shrouding, designed for through-hole solder mounting applications. This component operates at IEC ratings of 18.5A and 800V, with UL ratings of 15A and 300V. The part is currently active in production and widely stocked. Substitute parts are identified when equivalent mechanical and electrical specifications are required due to inventory constraints, supply chain considerations, or design flexibility within the allowed parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1629200000 is determined by strict equivalence in the following critical parameters:

• Mechanical Compatibility: Number of positions (9), pitch (7.50mm), header orientation (vertical), shrouding configuration (4-side), and mounting type (through-hole solder) must be identical
• Electrical Performance: Current and voltage ratings must meet or exceed the application requirements within either IEC or UL standards
• Environmental & Compliance: Operating temperature range, flammability rating (UL94 V-0), and regulatory compliance (RoHS, REACH) must be maintained
• Physical Dimensions: Contact tail length and insulation height must be compatible with PCB design specifications

The Phoenix Contact 1766738 qualifies as a substitute based on matching mechanical form factor, identical pitch and position count, equivalent shrouding, and compatible electrical ratings within the UL standard framework.

Parameter Comparison

Engineering Selection Recommendations

Both the Weidmüller 1629200000 and Phoenix Contact 1766738 maintain active product status and comply with RoHS and REACH regulatory requirements. Selection between these parts should be based on application voltage and current requirements:

• Weidmüller 1629200000: Suitable for applications requiring IEC ratings of 18.5A at 800V or UL ratings of 15A at 300V
• Phoenix Contact 1766738: Suitable for applications requiring UL ratings of 15A at 300V; IEC ratings are limited to 12A at 630V

Both parts feature UL94 V-0 flammability rating and tin contact mating finish. The contact tail length difference (0.126" vs 0.154") must be verified against PCB design specifications to ensure proper solder joint formation and mechanical clearance.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1766738 replace the Weidmüller 1629200000 in all applications?

A: Substitution is valid only when the application operates within the Phoenix Contact part's electrical ratings. If the design requires IEC compliance at 18.5A or 800V, the Weidmüller part is required. For UL-rated applications at 15A and 300V, both parts are electrically equivalent.

Q: What is the significance of the contact tail length difference?

A: The contact tail length (Weidmüller: 0.126", Phoenix Contact: 0.154") affects solder joint depth and PCB hole engagement. PCB design specifications must accommodate the longer tail of the Phoenix Contact part to ensure proper mechanical and electrical connection.

Q: Are both parts compatible with the same connector housing?

A: Both parts share identical pitch (7.50mm), position count (9), and insulation height (0.472"). Mechanical compatibility with mating connectors is maintained. However, the contact tail length difference may affect fit in some applications.

Q: What compliance certifications apply to both parts?

A: Both parts are RoHS Compliant (Weidmüller) or ROHS3 Compliant (Phoenix Contact) and REACH Unaffected. Both carry UL94 V-0 flammability rating and are suitable for industrial applications requiring flame-retardant materials.

Q: Which part should be selected for new designs?

A: Selection depends on electrical requirements and supply availability. Both parts are active in production. Verify that the chosen part's current and voltage ratings meet or exceed the application's design specifications.
