Weidmüller 1626690000 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1626690000 is an 11-position terminal block header with male pins, shrouded design, and 5.00mm pitch for vertical through-hole mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. The part operates within IEC ratings of 12A at 250V and UL ratings of 15A at 300V, with a temperature range of -20°C to 120°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1626690000 is determined by strict alignment of the following parameters:

• 11-position configuration with single level
• 5.00mm pitch spacing
• Vertical orientation with male pins
• Shrouded (4-side) design
• Solder termination for through-hole PCB mounting
• UL94 V-0 flammability rating
• Copper alloy contacts
• 12.00mm insulation height
• Electrical ratings: minimum 15A at 300V (UL standard)

The TE Connectivity AMP Connectors part 1-796642-1 meets all substitution criteria. While housing material differs (Polyamide PA66 versus Polybutylene Terephthalate), both materials satisfy UL94 V-0 requirements. Operating temperature range and contact tail length variations are within acceptable tolerance for equivalent functional performance in standard applications.

Engineering Selection Recommendations

The TE Connectivity 1-796642-1 is the direct functional equivalent for the obsolete Weidmüller 1626690000. Selection should be based on the following factors:

Product Status: The TE Connectivity part maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete Weidmüller component.

Compliance & Certifications: Both parts carry identical UL94 V-0 flammability ratings and EAR99 export classification. The TE Connectivity part holds RoHS Compliant status with MSL 1 (Unlimited), indicating superior environmental compliance and moisture handling characteristics.

Electrical Performance: Both parts meet or exceed the required 15A at 300V UL rating. The TE Connectivity part does not specify IEC current rating; however, the UL rating provides the controlling electrical specification for most applications.

Physical Compatibility: Identical pitch (5.00mm), position count (11), insulation height (12.00mm), and shrouded male pin configuration ensure direct PCB footprint compatibility. The 1.00mm difference in contact tail length (4.50mm versus 4.60mm) is within standard manufacturing tolerance and does not affect functional performance in standard through-hole applications.

Temperature Considerations: The TE Connectivity part operates to -40°C minimum versus -20°C for the Weidmüller part, providing extended low-temperature capability. The Weidmüller part extends to 120°C maximum versus 110°C for the TE Connectivity part. Application-specific temperature requirements should determine selection if operation near these limits is required.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-796642-1 be used as a direct replacement for the Weidmüller 1626690000 on existing PCBs?

A: Yes. Both parts share identical pitch (5.00mm), position count (11), insulation height (12.00mm), and shrouded male pin configuration. The contact tail length difference (1.00mm) does not affect through-hole soldering or functional performance in standard applications.

Q: What is the significance of the housing material difference between PBT and PA66?

A: Both materials meet UL94 V-0 flammability requirements. Polyamide (PA66) offers superior mechanical strength and chemical resistance, while Polybutylene Terephthalate (PBT) provides better dimensional stability. For standard terminal block applications, both materials are functionally equivalent.

Q: Does the color difference (black versus green) affect electrical performance?

A: No. Color is a cosmetic designation and does not affect electrical or mechanical performance. Selection should be based on application requirements or design specifications.

Q: What is the impact of the operating temperature range difference?

A: The TE Connectivity part (-40°C to 110°C) provides lower temperature capability than the Weidmüller part (-20°C to 120°C). For applications operating within -20°C to 110°C, both parts are equivalent. Applications requiring operation below -20°C or above 110°C require specific part selection.

Q: Is the TE Connectivity part RoHS compliant?

A: Yes. The TE Connectivity 1-796642-1 is RoHS Compliant with MSL 1 (Unlimited), indicating full compliance with Restriction of Hazardous Substances regulations and unlimited shelf life without moisture sensitivity concerns.

Q: Are there any packaging differences between these parts?

A: The Weidmüller part is listed as obsolete with no specified packaging. The TE Connectivity part is supplied in Bulk packaging. Confirm packaging requirements with your procurement specification.
