Substitute Part Grouping Explanation

Substitution of the 3M 926141-01-11-I is based on the following critical parameters that must align between the main part and substitute:

• Connector type: Header, Breakaway configuration
• Contact type: Male Pin
• Pitch specification: 0.100" (2.54mm) mating pitch
• Position count: 11 positions in single-row configuration
• Mounting method: Through-hole solder termination
• Fastening mechanism: Push-Pull engagement
• Current capacity: 2.5A minimum rating
• Operating temperature range: -40°C ~ 105°C
• Flammability compliance: UL94 V-0 rating
• Moisture sensitivity: MSL 1 (Unlimited)

The Molex 0423751864 satisfies these core substitution criteria, providing functional and mechanical compatibility for board-to-board or cable applications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0423751864 is an active product with current manufacturing support, providing a direct functional substitute for the obsolete 3M 926141-01-11-I. Both connectors meet UL94 V-0 flammability requirements and maintain MSL 1 moisture sensitivity classification.

Key differences exist in contact finish specification and insulation material composition. The 3M part features gold plating (10.0µin thickness) on copper alloy contacts with PBT insulation, while the Molex substitute uses tin plating (100.0µin thickness) with polyamide insulation. Both materials satisfy the stated flammability and environmental requirements.

Contact geometry variations are present: the Molex part exhibits longer mating contact length (0.488" versus 0.428") and post length (0.122" versus 0.100"), resulting in increased overall contact length (0.700" versus 0.628"). The Molex insulation height is slightly reduced (0.090" versus 0.100"). These dimensional differences must be evaluated against specific PCB layout and mating connector specifications in the target application.

Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications and support board-to-board or cable interconnection topologies.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0423751864 directly replace the 3M 926141-01-11-I in existing designs?

A: Functional compatibility is established through matching connector type, contact configuration, pitch, position count, and fastening mechanism. Physical compatibility requires verification of PCB footprint tolerance and mating connector depth specifications, as contact length and insulation height differ between the two parts.

Q: What is the significance of the contact finish difference between gold and tin plating?

A: Contact finish affects corrosion resistance and electrical performance in specific environments. Gold plating provides superior corrosion resistance in high-humidity or corrosive atmospheres. Tin plating offers adequate performance in standard industrial environments and is more cost-effective. Selection depends on application environment and reliability requirements.

Q: Are there compatibility concerns with the insulation material change from PBT to polyamide?

A: Both materials meet UL94 V-0 flammability requirements and maintain equivalent moisture sensitivity classification (MSL 1). Polyamide exhibits different mechanical properties and chemical resistance profiles. Application-specific environmental exposure (temperature cycling, chemical exposure, humidity) should be evaluated against material datasheets.

Q: How do the dimensional differences affect board design?

A: The Molex part has longer overall contact length (0.700" versus 0.628") and slightly reduced insulation height (0.090" versus 0.100"). These variations may impact PCB trace routing, component placement clearances, and mating connector engagement depth. PCB layout review is necessary before implementation.

Q: What is the current availability status of each part?

A: The 3M 926141-01-11-I is classified as obsolete with limited inventory (1180 pcs reported). The Molex 0423751864 is an active product with current manufacturing support and reported inventory of 852 pcs. For new designs or long-term production, the active Molex part is the recommended selection.

Q: Are both parts RoHS compliant?

A: The Molex 0423751864 is specified as ROHS3 Compliant with REACH Unaffected status. Compliance information for the 3M part is not provided in the available specifications.
