Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3M 926141-01-04-I is determined by strict alignment of the following critical parameters:

• Connector Type: Header, Breakaway configuration
• Contact Type: Male Pin
• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 4
• Number of Rows: 1
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Shrouding: Unshrouded
• Style: Board to Board or Board to Board/Cable compatible

The Molex 0423751857 meets these core substitution criteria. While secondary parameters such as contact finish material (Gold vs. Tin), contact length dimensions, and insulation material composition differ, these variations remain within acceptable tolerance for equivalent functional performance in standard board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0423751857 is the designated manufacturer-recommended substitute for the obsolete 3M 926141-01-04-I. Both components maintain UL94 V-0 flammability compliance and unlimited moisture sensitivity classification. The Molex part carries Active product status, ensuring continued availability and supply chain support.

The primary technical differences—tin contact finish versus gold, and polyamide insulation versus polybutylene terephthalate—do not compromise functional equivalence for standard board-to-board interconnection applications. Both materials meet the specified flammability and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0423751857 directly replace the 3M 926141-01-04-I in existing designs?

A: Yes. Both connectors share identical pitch spacing (0.100"), position count (4), row configuration (1), mounting method (through-hole solder), and fastening mechanism (push-pull). Mechanical and electrical compatibility is maintained.

Q: What is the significance of the contact finish difference (Gold vs. Tin)?

A: Contact finish affects corrosion resistance and contact resistance characteristics. Gold provides superior corrosion resistance; tin offers adequate performance in standard environments. The choice depends on application-specific environmental exposure and contact resistance requirements.

Q: Are there packaging differences between these parts?

A: The 3M 926141-01-04-I packaging information is not specified in the provided data. The Molex 0423751857 is supplied in Bulk packaging.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are classified as EAR99 for export control purposes, share identical HTSUS codes (8536.69.4040), and maintain UL94 V-0 flammability ratings.

Q: What is the difference in insulation material composition?

A: The 3M part uses polybutylene terephthalate (PBT) with polyester and glass filler. The Molex part uses polyamide (PA) nylon with glass filler. Both materials are glass-filled thermoplastics with UL94 V-0 ratings suitable for connector applications.
