Weidmüller 1761632001 Terminal Block Header – Equivalent & Substitute Parts

Part Overview

The Weidmüller 1761632001 is an 11-position terminal block header with male pins, shrouded design, and 4.6mm pitch for 90° right-angle through-hole mounting. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. The part operates within IEC ratings of 15A at 320V and UL ratings of 10A at 300V, with operating temperature range of -50°C to 100°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1761632001 is determined by the following critical parameters:

• Position Count & Pitch: 11 positions at 0.138" (4.60mm) spacing
• Header Type & Orientation: Male pins, shrouded (4-side), 90° right-angle configuration
• Termination & Mounting: Solder termination with through-hole mounting
• Electrical Performance: Current and voltage ratings sufficient for the application
• Compliance & Safety: RoHS compliance and UL94 V-0 flammability rating

Two substitute parts meet these criteria with varying degrees of parameter alignment:

Direct Substitute (Weidmüller 1841720000): Identical manufacturer, series, and electrical specifications. Primary difference is contact tail length (0.126" vs. 0.059"), which affects PCB insertion depth but maintains functional compatibility.

Cross-Manufacturer Substitute (TE Connectivity 1-284512-1): Equivalent mechanical and electrical configuration from an alternative manufacturer. Notable differences include housing material (Polyamide vs. LCP), contact material (Phosphor Bronze vs. Copper Alloy), and operating temperature range (-40°C to 110°C vs. -50°C to 100°C).

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: Weidmüller 1841720000 is the primary substitute. Both parts share identical manufacturer lineage, series designation, and electrical specifications. The part is currently in active production status with 934 units in stock. The increased contact tail length (0.126" vs. 0.059") requires PCB footprint verification to ensure proper insertion depth and solder joint formation.

For Cross-Manufacturer Substitution: TE Connectivity 1-284512-1 provides functional equivalence with active product status and 948 units available. This option is suitable when Weidmüller parts are unavailable. Housing material and contact material differences do not affect electrical performance within the specified operating parameters. The extended operating temperature range (-40°C to 110°C) provides additional thermal margin compared to the original part.

Both substitutes maintain RoHS compliance and UL94 V-0 flammability certification, meeting regulatory requirements for the original application.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1841720000 be used as a direct drop-in replacement for the 1761632001?

A: Electrical and mechanical compatibility is confirmed. The primary consideration is contact tail length: 1841720000 has 0.126" tails versus 0.059" on the original. PCB footprint and solder pad design must accommodate the longer tail length to ensure proper connection and mechanical stability.

Q: What are the key differences between the Weidmüller and TE Connectivity substitutes?

A: Both maintain 11-position, 4.6mm pitch, 90° right-angle configuration with solder termination. Differences include housing material (LCP glass-filled vs. Polyamide), contact material (Copper Alloy vs. Phosphor Bronze), and operating temperature range (-50°C to 100°C vs. -40°C to 110°C). Electrical ratings are equivalent or superior in all cases.

Q: Are there packaging considerations when ordering substitutes?

A: The Weidmüller 1841720000 is supplied in bulk packaging. The TE Connectivity 1-284512-1 is also supplied in bulk. Verify packaging requirements with your procurement process, as the original 1761632001 packaging specification was not provided.

Q: Do the substitute parts meet the same compliance standards as the original?

A: Both substitutes are RoHS compliant and carry UL94 V-0 flammability certification, matching the original part's compliance profile. REACH status for the TE Connectivity part is listed as vendor-undefined; verify with the supplier if REACH compliance documentation is required.

Q: What is the current availability status of these parts?

A: The original Weidmüller 1761632001 is obsolete with 1016 units in stock. The Weidmüller 1841720000 is active production with 934 units available. The TE Connectivity 1-284512-1 is active production with 948 units available.
