3M 926141-01-04-EU Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 926141-01-04-EU is a through-hole rectangular connector header with 4 positions at 0.100" (2.54mm) pitch. This component is classified as obsolete, making identification of equivalent substitute parts essential for ongoing design support and production continuity. The connector features a breakaway header design with unshrouded configuration, suitable for board-to-board applications requiring push-pull fastening.

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 926141-01-04-EU is determined by the following critical parameters:

Pitch - Mating: 0.100" (2.54mm) - must match exactly
Number of Positions: 4 - must match exactly
Number of Rows: 1 - must match exactly
Contact Type: Male Pin - must match exactly
Mounting Type: Through Hole - must match exactly
Termination: Solder - must match exactly
Fastening Type: Push-Pull - must match exactly
Material Flammability Rating: UL94 V-0 - must match or exceed
Moisture Sensitivity Level: 1 (Unlimited) - must match

Both substitute parts listed meet these core substitution criteria. The Molex 0423751857 and Amphenol ICC 77311-132-04LF are active products with equivalent mechanical and electrical specifications suitable for direct replacement in applications previously using the obsolete 3M connector.

Engineering Selection Recommendations

Both substitute parts are active products with current manufacturing support, addressing the obsolescence of the original 3M component. Selection between the two substitutes depends on specific application requirements:

Molex 0423751857 is suitable for applications where tin contact finish is acceptable and where the connector may interface with cable assemblies in addition to board-to-board configurations. This part carries ROHS3 compliance certification.

Amphenol ICC 77311-132-04LF offers an extended operating temperature range (-65°C ~ 125°C versus -40°C ~ 105°C) and higher current rating per contact (3A versus 2.5A). The gold contact finish option aligns more closely with the original 3M specification. This part carries RoHS compliance and is REACH affected.

Both parts meet UL94 V-0 flammability requirements and maintain MSL 1 (Unlimited) moisture sensitivity levels. Contact length variations between the original and substitutes are minor and typically accommodate standard PCB through-hole spacing without design modification.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0423751857 be used as a direct replacement for the 3M 926141-01-04-EU?

A: Yes. Both connectors share identical pitch (0.100"), position count (4), row configuration (1), contact type (male pin), mounting method (through hole), and fastening mechanism (push-pull). The Molex part meets all core substitution criteria.

Q: What is the primary difference between the Molex and Amphenol ICC substitutes?

A: The Amphenol ICC 77311-132-04LF provides extended operating temperature range (-65°C to 125°C) and higher current rating (3A per contact). The Molex 0423751857 offers broader style compatibility (board-to-board or cable). Contact finish differs: Molex uses tin, while Amphenol ICC offers gold or gold GXT™ options.

Q: Are there packaging differences between these substitutes?

A: Yes. The Molex 0423751857 is supplied in bulk packaging, while the Amphenol ICC 77311-132-04LF is supplied in bag packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Do the contact length variations affect PCB design?

A: Contact length differences are minor (ranging from 0.406" to 0.488" mating length). Standard PCB through-hole designs accommodate these variations without modification. Verify specific board thickness and component clearance requirements for your application.

Q: Which substitute offers better compliance for regulated applications?

A: Both parts meet UL94 V-0 flammability requirements. The Amphenol ICC part carries RoHS compliance and is REACH affected, providing broader regulatory coverage for European and regulated markets. The Molex part carries ROHS3 compliance.
