926141-01-02-EU Equivalent & Substitute Parts

Part Overview

The 3M 926141-01-02-EU is a rectangular connector header designed for through-hole mounting applications. This 2-position, 0.100" (2.54mm) pitch connector features male pins with gold-plated contacts and is classified as obsolete. Due to its obsolete status, identifying equivalent substitute parts from active manufacturers is essential for ongoing design support, production continuity, and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 926141-01-02-EU is determined by the following critical parameters:

• Pitch and Position Count: 0.100" (2.54mm) pitch with 2 positions in a single row
• Contact Configuration: Male pin contacts with square shape
• Mounting and Termination: Through-hole solder termination with push-pull fastening
• Electrical Performance: 2.5A current rating capability
• Environmental Compliance: UL94 V-0 flammability rating and MSL 1 classification
• Connector Style: Board-to-board or board-to-cable configuration

The substitute parts listed below maintain compatibility with these core parameters while originating from active manufacturers with current product status.

Parameter Comparison

Engineering Selection Recommendations

Molex 0423751855: This part is recommended as the primary substitute. It maintains active product status with high inventory availability (26,731 pcs). The KK254 series connector shares the critical 2.54mm pitch, 2-position configuration, and push-pull fastening. The part is RoHS3 compliant and REACH unaffected, providing regulatory alignment for modern applications. Contact finish differs (tin versus gold), with thicker plating (100.0µin) providing enhanced durability. Insulation material is polyamide glass-filled rather than PCT, maintaining UL94 V-0 compliance. Overall contact length is slightly longer (0.700" versus 0.628"), which may require PCB layout verification.

Amphenol ICC 79429-102H: This part serves as an alternative substitute with active product status. The BERGSTIK® II series maintains the 2.54mm pitch and 2-position configuration with gold contact finish options. Contact material is phosphor bronze, differing from the original copper alloy. The part supports both press-fit and solder termination, providing installation flexibility. RoHS non-compliance status requires consideration for applications with RoHS requirements. Overall contact length (0.695") is closer to the original specification than the Molex alternative.

Both substitutes maintain electrical compatibility through identical pitch, position count, fastening type, and flammability rating. Selection should be based on specific application requirements regarding contact finish, insulation material, regulatory compliance, and PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0423751855 directly replace the 3M 926141-01-02-EU?

A: The Molex part maintains functional compatibility through identical pitch (2.54mm), position count (2), and fastening type (push-pull). However, differences exist in contact finish (tin versus gold), contact length (0.700" versus 0.628"), and insulation material (polyamide glass-filled versus PCT). PCB layout and mating connector specifications must be verified before substitution.

Q: What is the significance of contact finish differences between the parts?

A: The original 3M part features 10.0µin gold plating, while the Molex substitute provides 100.0µin tin plating. Gold offers superior corrosion resistance and lower contact resistance, while tin provides cost efficiency and adequate performance for general-purpose applications. The thicker tin plating on the Molex part compensates for lower inherent corrosion resistance. Application environment and mating connector material should guide selection.

Q: Are there compliance differences between the substitutes?

A: The Molex 0423751855 is RoHS3 compliant and REACH unaffected, suitable for regulated markets. The Amphenol ICC 79429-102H is RoHS non-compliant, requiring evaluation against specific application requirements. Both parts maintain UL94 V-0 flammability rating and MSL 1 classification.

Q: How do contact length variations affect compatibility?

A: Contact length differences (0.628" original, 0.700" Molex, 0.695" Amphenol) impact mating depth and PCB hole positioning. The longer contacts on substitute parts may require PCB layout adjustment or verification that mating connectors accommodate the increased length without mechanical interference.

Q: What is the current rating capability of the substitute parts?

A: The original 3M part is rated for 2.5A. Current ratings for the Molex and Amphenol substitutes are not specified in the provided data. Applications requiring confirmed 2.5A capability should contact manufacturers directly for electrical performance verification.

Q: Can these parts be used interchangeably in existing designs?

A: Interchangeability requires verification of mating connector compatibility, PCB layout accommodation for contact length variations, and confirmation that insulation material and contact finish meet application requirements. Prototype testing is recommended before full production transition.
