926141-01-03-EU Equivalent & Substitute Parts

Part Overview

The 926141-01-03-EU is a rectangular connector header manufactured by 3M, designed for through-hole board-to-board applications with 3 positions at 0.100" (2.54mm) pitch. This part is classified as obsolete, making identification of active equivalent components essential for ongoing design support and procurement continuity. Substitute parts must maintain electrical and mechanical compatibility within the specified parameter tolerances for this connector category.

Substitute Part Grouping Explanation

Substitution eligibility for the 926141-01-03-EU is determined by the following critical parameters:

Pitch - Mating: 0.100" (2.54mm) — mechanical and electrical interface standard
Number of Positions: 3 — connector capacity requirement
Number of Rows: 1 — physical layout constraint
Contact Type: Male Pin — mating interface specification
Mounting Type: Through Hole — PCB assembly method
Termination: Solder — connection method
Style: Board to Board — application category
Shrouding: Unshrouded — physical form factor
Contact Shape: Square — contact geometry
Material Flammability Rating: UL94 V-0 — safety compliance

The identified substitute parts meet these core parameters while maintaining functional equivalence. Variations in contact length, contact finish, insulation material, and operating temperature range are within acceptable tolerances for this connector category and do not preclude substitution.

Engineering Selection Recommendations

Both substitute parts are classified as active products, ensuring long-term availability and manufacturing support compared to the obsolete 926141-01-03-EU.

The Molex 0423751856 (KK254 series) is manufacturer-recommended and maintains full compatibility with the core electrical and mechanical specifications. This part is available in high inventory (8622 units) and carries RoHS3 compliance certification.

The Amphenol ICC 77311-132-03LF (BERGSTIK® series) provides an alternative with extended operating temperature range (-65°C ~ 125°C) and higher current rating per contact (3A). This part carries RoHS compliance and is REACH affected. Inventory availability is lower (641 units).

Selection between these substitutes should be based on application-specific requirements for operating temperature range, current capacity, and long-term supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0423751856 directly replace the 3M 926141-01-03-EU?

A: Yes. Both parts share identical pitch (0.100"), position count (3), row configuration (1), contact type (male pin), mounting method (through hole), and termination (solder). The Molex part is manufacturer-recommended and maintains UL94 V-0 flammability rating and MSL 1 classification.

Q: What is the difference in contact length between these parts?

A: The 3M part has a mating contact length of 0.428" (10.87mm), the Molex part 0.488" (12.40mm), and the Amphenol part 0.406" (10.30mm). These variations are within acceptable tolerances for this connector category and do not affect board-to-board mating compatibility.

Q: Does the Amphenol 77311-132-03LF offer advantages over the Molex substitute?

A: The Amphenol part provides extended operating temperature range (-65°C ~ 125°C versus unspecified for Molex) and higher current rating (3A per contact versus 2.5A for the original). Selection depends on application thermal and current requirements.

Q: Are all three parts RoHS compliant?

A: The Molex 0423751856 is RoHS3 compliant. The Amphenol 77311-132-03LF is RoHS compliant. The original 3M part status is not specified in the provided data.

Q: What is the inventory status for these substitutes?

A: Molex 0423751856 has 8622 units in stock. Amphenol 77311-132-03LF has 641 units in stock. Both are active products with ongoing manufacturing support.
