3M 961124-6700-AR-TP Equivalent & Substitute Parts

Part Overview

The 3M 961124-6700-AR-TP is a rectangular connector header designed for surface mount applications with 24 positions at 0.100" (2.54mm) pitch. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. The connector features male pin contacts with gold-plated mating surfaces, suitable for board-to-board applications with push-pull fastening and a current rating of 2A.

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 961124-6700-AR-TP is determined by the following critical parameters:

Connector type (Header) and contact type (Male Pin)
Pitch specification (0.100" / 2.54mm)
Position count (24 positions, single row)
Mounting method (Surface Mount)
Termination type (Solder)
Fastening mechanism (Push-Pull)
Contact finish (Gold plating on mating surface)
Flammability compliance (UL94 V-0)

The identified substitute parts meet these core electrical and mechanical requirements while maintaining compatibility with the original application interface.

Engineering Selection Recommendations

Both substitute parts are classified as active products, providing supply chain continuity compared to the obsolete 3M original. The Würth Elektronik 61002418221 and Sullins GBC24SFBN-M30 maintain compliance with UL94 V-0 flammability requirements and MSL 1 moisture sensitivity specifications.

The Würth Elektronik part operates across an extended temperature range (-40°C ~ 125°C) and supports higher current capacity (3A), with ROHS3 and REACH compliance documentation. The Sullins part extends the operating temperature range further (-65°C ~ 150°C) and also provides ROHS3 and REACH compliance, with phosphor bronze contact material and breakaway header capability.

Selection between substitutes depends on application-specific requirements for operating temperature range, current capacity, and mechanical form factor compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 61002418221 directly replace the 3M 961124-6700-AR-TP?

A: The Würth Elektronik part meets the core substitution criteria: 24-position, 0.100" pitch, surface mount header with male pins, gold-plated contacts, and UL94 V-0 compliance. The contact length for mating is 0.236" (6.00mm) compared to the original 0.260" (6.60mm), and insulation height is 0.100" (2.54mm) versus 0.098" (2.50mm). These dimensional variations must be evaluated against specific PCB and mating connector design constraints.

Q: What is the primary difference between the Würth Elektronik and Sullins substitutes?

A: Both parts maintain the required 24-position, 0.100" pitch configuration and push-pull fastening. The Sullins part features a breakaway header option, phosphor bronze contacts, and extended operating temperature range (-65°C ~ 150°C) compared to Würth Elektronik (-40°C ~ 125°C). The Sullins contact length for mating is 0.318" (8.08mm), the longest of the three options.

Q: Are there compliance or regulatory differences between the substitutes?

A: Both active substitutes carry ROHS3 and REACH compliance certifications. The original 3M part does not specify these compliance statuses. All three parts meet UL94 V-0 flammability requirements and carry MSL 1 moisture sensitivity ratings.

Q: How do current ratings affect part selection?

A: The original 3M part is rated for 2A, while both substitutes support 3A. Applications requiring exactly 2A operation can use either substitute without derating concerns. Applications approaching 2A limits benefit from the higher 3A rating of the substitutes.

Q: What packaging considerations apply to these substitutes?

A: The Würth Elektronik part is supplied in tube packaging, while the Sullins part is supplied in bulk packaging. The original 3M part packaging is not specified. Packaging selection affects handling, storage, and automated assembly compatibility.
