Weidmüller 1625000000 Terminal Block Header Equivalent & Substitute Parts

Part Overview

The Weidmüller 1625000000 is a 10-position vertical terminal block header with 0.300" (7.62mm) pitch, male pins, and 4-side shrouding. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations. The part operates at 15A (UL) / 15A (IEC) and 300V (UL) / 500V (IEC), with solder termination and through-hole mounting. Suitable alternatives must maintain electrical ratings, mechanical compatibility, and shrouded header configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Position Count & Pitch: All substitute parts maintain 10 positions with 0.300" (7.62mm) pitch, except 1766741 which uses 0.295" (7.50mm) pitch
• Header Configuration: All parts feature male pins with 4-side shrouding in vertical orientation
• Electrical Ratings: Substitute parts must support minimum 15A (UL) and 300V (UL) operation
• Termination & Mounting: All parts use solder termination with through-hole or solder mounting compatibility
• Contact Finish & Material: Tin-plated contacts with copper alloy or brass construction
• Flammability Compliance: UL94 V-0 rating maintained across all active substitutes

The following parts qualify as direct equivalents or functional substitutes:

1. 1-796980-0 (TE Connectivity): Exact pitch match, active status, extended temperature range
2. 1766741 (Phoenix Contact): Minor pitch variance (7.50mm vs 7.62mm), active status, higher IEC voltage rating
3. 1766851 (Phoenix Contact): Exact pitch match, active status, higher IEC voltage rating
4. OSTOQ100150 (On Shore Technology): Exact pitch match, active status, solder mounting variant

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Exact Pitch Match - 7.62mm):

• 1-796980-0 (TE Connectivity AMP Buchanan): Active product with extended operating temperature range (-40°C ~ 110°C). ROHS3 compliant. Recommended for applications requiring broader temperature performance and modern compliance certifications.

• 1766851 (Phoenix Contact COMBICON GMSTBVA): Active product with higher IEC voltage rating (630V). ROHS3 compliant and REACH unaffected. Suitable for high-voltage applications exceeding 500V IEC requirements.

• OSTOQ100150 (On Shore Technology OSTOQ): Active product with solder mounting variant. ROHS3 compliant. Applicable for direct PCB solder applications where through-hole mounting is not required.

Secondary Substitute (Minor Pitch Variance - 7.50mm):

• 1766741 (Phoenix Contact COMBICON GMSTBVA): Active product with 0.295" (7.50mm) pitch, representing a 0.05mm deviation from the original 7.62mm specification. Higher IEC voltage rating (630V). RoHS compliant. Use only when mechanical tolerance analysis confirms compatibility with mating connectors and PCB layouts.

All substitute parts maintain UL94 V-0 flammability compliance and tin-plated contact finishes. Selection should prioritize active products with current compliance certifications (ROHS3, REACH unaffected) over the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can 1766741 with 7.50mm pitch directly replace the 1625000000 with 7.62mm pitch?

A: Direct replacement requires mechanical compatibility verification. The 0.05mm pitch difference may affect mating connector alignment and PCB footprint fit. Consult PCB layout tolerances and connector specifications before substitution.

Q: What is the primary difference between 1-796980-0 and 1766851?

A: Both maintain 7.62mm pitch and 15A/300V UL ratings. The 1-796980-0 offers extended operating temperature (-40°C ~ 110°C) and uses copper alloy contacts. The 1766851 provides higher IEC voltage (630V) and uses polyamide housing. Selection depends on application temperature and voltage requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 1-796980-0, 1766851, and OSTOQ100150 are ROHS3 compliant. The 1766741 is RoHS compliant. All meet modern environmental regulations.

Q: Does OSTOQ100150 use through-hole or solder mounting?

A: OSTOQ100150 uses solder mounting, differing from the through-hole configuration of other substitutes. This variant is suitable for direct PCB solder applications only.

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

A: Contact tail length varies from 0.138" (4.60mm) to 0.177" (4.50mm) across substitutes. Verify PCB hole depth and solder pad design compatibility before selection. Shorter tails may require PCB design adjustment.

Q: Can I use OSTOQ100150 if my design requires through-hole mounting?

A: No. OSTOQ100150 is specified for solder mounting only. Use 1-796980-0, 1766741, or 1766851 for through-hole applications.

Q: Which substitute offers the best temperature performance?

A: The 1-796980-0 provides the widest operating range (-40°C ~ 110°C), exceeding the original part's -20°C ~ 100°C specification.
