Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 926141-01-07-I is determined by the following critical parameters:

• Pitch and Position Configuration: 0.100" (2.54mm) pitch with 7 positions in single row
• Contact Type and Termination: Male pin contacts with solder termination
• Mounting and Fastening: Through-hole mounting with push-pull fastening
• Connector Style: Board-to-board or board-to-cable header configuration
• Electrical Performance: Current rating and operating temperature compatibility
• Compliance: UL94 V-0 flammability rating and moisture sensitivity level

The identified substitute parts meet these core electrical and mechanical parameters, enabling direct functional replacement in applications originally designed for the 3M 926141-01-07-I.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are classified as active products with current manufacturing support, providing long-term availability advantages over the obsolete 3M 926141-01-07-I.

Molex 0423751860 (KK254 Series): This connector maintains the same 0.100" pitch and 7-position configuration with board-to-board or cable compatibility. The part carries UL94 V-0 flammability certification and unlimited moisture sensitivity rating. Contact finish differs from the original (tin versus gold), which may affect corrosion resistance in specific environmental conditions. This part is suitable for general-purpose, automotive, medical, and telecommunications applications.

TE Connectivity 826119-7 (AMPMODU Mod II Series): This connector provides the same core electrical and mechanical specifications with extended operating temperature range (-65°C to 105°C versus -40°C to 105°C) and higher current rating (5A versus 2.5A). Gold contact finish matches the original specification. The part carries UL94 V-0 flammability certification and unlimited moisture sensitivity rating. RoHS compliance is confirmed.

Selection between these substitutes depends on application-specific requirements regarding contact finish material, temperature extremes, and current handling capacity.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0423751860 directly replace the 3M 926141-01-07-I?

A: The Molex part meets all core mechanical and electrical parameters: 0.100" pitch, 7 positions, single row, through-hole mounting, solder termination, and push-pull fastening. The primary difference is contact finish material (tin versus gold). In applications where contact finish material is not a critical design parameter, direct substitution is feasible.

Q: What is the significance of the contact finish difference between the original and substitute parts?

A: The 3M original uses gold plating (10.0µin thickness), while the Molex substitute uses tin plating (100.0µin thickness). Gold provides superior corrosion resistance and lower contact resistance in low-signal applications. Tin offers adequate performance in most industrial environments but may exhibit higher contact resistance over extended service life in corrosive conditions.

Q: Does the TE Connectivity 826119-7 offer advantages over the Molex substitute?

A: The TE Connectivity part provides extended operating temperature range (-65°C versus -40°C minimum) and higher current rating (5A versus unspecified for Molex). Contact finish matches the original specification (gold). These characteristics make it suitable for applications requiring enhanced thermal performance or higher current capacity.

Q: Are both substitute parts compatible with the original connector housing and mating components?

A: Both substitutes maintain the 0.100" (2.54mm) pitch and square contact geometry, ensuring mechanical compatibility with standard 2.54mm pitch connector housings and mating receptacles. Physical dimensions vary slightly between manufacturers, requiring verification of PCB footprint and clearance in space-constrained applications.

Q: What compliance certifications apply to these substitute parts?

A: Both parts carry UL94 V-0 flammability certification and unlimited moisture sensitivity level (MSL 1). The TE Connectivity part includes RoHS compliance confirmation. The Molex part is ROHS3 compliant and REACH unaffected.
