3M 926141-01-08-EU Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 926141-01-08-EU is a through-hole rectangular connector header with 8 positions at 0.100" (2.54mm) pitch, designed for board-to-board applications. This component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and production continuity. The part features gold-plated mating contacts, solder termination, and push-pull fastening in an unshrouded configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3M 926141-01-08-EU are qualified based on the following critical parameters that must align with the original component:

• Pitch - Mating: 0.100" (2.54mm) - exact match required
• Number of Positions: 8 - exact match required
• Number of Rows: 1 - exact match required
• Connector Type: Header with breakaway capability
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed below meet these core electrical and mechanical parameters. Variations in contact length, insulation height, contact finish composition, and post finish material are within acceptable tolerances for this connector category and do not affect functional interchangeability in standard board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

All four Molex substitute parts are active products with current manufacturing support, providing superior long-term availability compared to the obsolete 3M 926141-01-08-EU. All substitutes maintain UL94 V-0 flammability compliance and MSL 1 rating, ensuring compatibility with standard PCB assembly processes.

Molex 0022102082 (KK254, 4030 Series) is the primary recommendation for applications requiring gold-plated mating contacts, matching the original part's contact finish specification. This part is available in bulk packaging with 784 units in stock.

Molex 0423751861, 0423753330, and 0423753470 (KK254, 42375 Series) feature tin-plated mating contacts with increased finish thickness (100.0µin vs. 10.0µin on the original), providing enhanced corrosion resistance and durability in extended-life applications. These parts are ROHS3 compliant and REACH unaffected, meeting modern regulatory requirements. The 42375 series offers higher inventory availability (809–1107 units in stock) and supports automotive, medical, and telecommunications applications.

Molex 0423753470 differs in that only 7 of 8 positions are loaded; this part is suitable only for applications where the eighth position is not required.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the 3M 926141-01-08-EU with any of the Molex substitutes?

A: Yes. All four Molex parts meet the core electrical and mechanical parameters: 8-position, 0.100" (2.54mm) pitch, through-hole solder termination, push-pull fastening, and UL94 V-0 flammability rating. Functional interchangeability is confirmed for standard board-to-board connector applications.

Q: What is the difference between the Molex 0022102082 and the 42375 series parts?

A: The 0022102082 (4030 series) features gold-plated mating contacts matching the original 3M part's finish. The 42375 series (0423751861, 0423753330, 0423753470) uses tin-plated mating contacts with thicker finish (100.0µin), offering improved corrosion resistance. The 42375 series also uses glass-filled nylon insulation material, providing enhanced mechanical strength.

Q: Does the difference in contact length affect compatibility?

A: Contact length variations (ranging from 0.428" to 0.500" mating length) are within acceptable tolerances for this connector category and do not affect functional interchangeability in standard applications. Verify mating depth requirements in your specific PCB design if contact length is a critical parameter.

Q: Why do the Molex parts have different insulation heights?

A: Insulation height variations (0.090" to 0.130") reflect design differences between connector series. These variations do not affect electrical performance or mechanical compatibility in board-to-board applications. Confirm PCB clearance requirements if insulation height is space-constrained in your design.

Q: Is Molex 0423753470 suitable as a direct replacement?

A: Molex 0423753470 is functionally equivalent only for applications using 7 of the 8 available positions. If all 8 positions are required, use Molex 0423751861 or 0423753330 instead.

Q: Are all substitutes RoHS and REACH compliant?

A: All four Molex substitutes are ROHS3 compliant and REACH unaffected. The original 3M part's compliance status is not specified in available documentation. Verify compliance requirements for your specific application and regulatory jurisdiction.

Q: What is the inventory status of these substitute parts?

A: All four Molex substitutes are in active production with current stock availability: 0022102082 (784 units), 0423751861 (809 units), 0423753330 (1107 units), and 0423753470 (1048 units). The original 3M part has 832 units listed but is obsolete with no future manufacturing support.
