Weidmüller 1629640000 Terminal Block Header — Equivalent & Substitute Parts

Part Overview

The Weidmüller 1629640000 is a 9-position terminal block header with male pins, shrouded on four sides, designed for 0.295" (7.50mm) pitch vertical through-hole mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. Substitute parts must maintain electrical performance, mechanical compatibility, and mounting characteristics to ensure direct interchangeability in existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1629640000 is determined by the following critical parameters:

Primary Matching Criteria:

• 9-position configuration
• 0.295" (7.50mm) pitch spacing
• Vertical header orientation
• Male pin configuration with 4-side shrouding
• Through-hole mounting with solder termination
• UL94 V-0 flammability rating
• Tin contact mating finish

Electrical Compatibility Criteria:

• UL voltage rating of 300V minimum
• UL current rating of 15A minimum
• IEC voltage rating of 500V or higher preferred for margin
• IEC current rating of 12A or higher acceptable

Mechanical Compatibility Criteria:

• Insulation height of 0.472" (12.00mm)
• Contact tail length within 0.154" to 0.177" (3.90mm to 4.50mm) range
• Housing material compatible with PBT or equivalent thermoplastic

The Phoenix Contact 1766738 and On-Shore Technology OSTOQ09A150 meet these criteria and are classified as active products with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1766738 (COMBICON GMSTBVA Series)

This substitute maintains full electrical compatibility with UL ratings of 15A at 300V and exceeds IEC requirements at 12A and 630V. The component is active in production with ROHS3 compliance certification. Mechanical dimensions align with the original specification, including matching insulation height of 0.472" (12.00mm) and compatible contact tail length of 0.154" (3.90mm). The housing material composition (Polyamide/Nylon) provides equivalent thermal and mechanical performance to the original PBT construction. This part is recommended as the primary substitute for direct replacement applications.

On-Shore Technology OSTOQ09A150 (OSTOQ Series)

This substitute meets the core 9-position, 7.50mm pitch, vertical header configuration with male pins and 4-side shrouding. The component is active in production with ROHS3 compliance. Operating temperature range extends to -30°C to 105°C, providing broader thermal coverage than the original specification. However, the insulation height of 0.157" (4.00mm) differs significantly from the original 0.472" (12.00mm), which may affect mechanical fit in applications with specific PCB clearance requirements. Electrical specifications for IEC and UL current ratings are not provided in available documentation. This part is suitable for applications where thermal range extension is beneficial and mechanical envelope constraints permit the reduced insulation height.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1766738 be used as a direct drop-in replacement for the Weidmüller 1629640000?

A: Yes, the Phoenix Contact 1766738 is mechanically and electrically compatible for direct replacement. Both components share identical 9-position configuration, 0.295" (7.50mm) pitch, vertical orientation, and 0.472" (12.00mm) insulation height. Electrical ratings meet or exceed the original specification, and both carry UL94 V-0 flammability certification.

Q: What is the primary difference between the Phoenix Contact and On-Shore Technology substitutes?

A: The Phoenix Contact 1766738 maintains the original insulation height of 0.472" (12.00mm), while the On-Shore Technology OSTOQ09A150 has a reduced insulation height of 0.157" (4.00mm). This dimensional difference may affect mechanical fit depending on PCB layout and clearance requirements. The Phoenix Contact part is recommended when mechanical compatibility with existing designs is critical.

Q: Are both substitute parts RoHS compliant?

A: Yes, both the Phoenix Contact 1766738 and On-Shore Technology OSTOQ09A150 are ROHS3 compliant. The original Weidmüller 1629640000 RoHS status is not specified in available documentation.

Q: What is the significance of the IEC current rating difference between the Weidmüller and Phoenix Contact parts?

A: The Weidmüller 1629640000 carries a 15A IEC rating, while the Phoenix Contact 1766738 is rated at 12A IEC. Both meet the 15A UL requirement. For applications operating within 12A to 15A range, the Phoenix Contact part provides adequate performance. Applications requiring sustained operation above 12A should reference the specific load profile and thermal conditions to confirm suitability.

Q: Can the On-Shore Technology OSTOQ09A150 be used in applications with tight PCB clearance constraints?

A: The On-Shore Technology OSTOQ09A150 has a reduced insulation height of 0.157" (4.00mm) compared to the original 0.472" (12.00mm). This reduced height may provide advantages in space-constrained designs. However, mechanical fit must be verified against specific PCB layout requirements and connector mating specifications before implementation.

Q: What certifications should be verified when selecting a substitute part?

A: Verify UL94 V-0 flammability rating for safety-critical applications, UL and IEC electrical ratings for the intended operating voltage and current, and RoHS compliance status for regulatory requirements in target markets. Both active substitute parts carry these certifications.
