Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 926141-01-05-EU is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — mechanical and electrical compatibility requirement
• Number of Positions: 5 — circuit configuration requirement
• Number of Rows: 1 — physical layout requirement
• Connector Type: Header, Breakaway — functional form factor
• Contact Type: Male Pin — mating interface requirement
• Mounting Type: Through Hole — PCB assembly compatibility
• Termination: Solder — connection method
• Fastening Type: Push-Pull — mechanical engagement method
• Material Flammability Rating: UL94 V-0 — safety compliance

All three substitute parts meet these core substitution criteria. Variations in contact length, insulation height, contact finish composition, and post length do not preclude functional equivalence in standard board-to-board applications where the mating interface and pitch geometry are preserved.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products with current manufacturing status, providing supply chain continuity for the obsolete 3M 926141-01-05-EU.

Molex 0423751858 (KK254 Series) is an active product supplied in bulk packaging. This part maintains the core 5-position, 2.54mm pitch header configuration with push-pull fastening and UL94 V-0 flammability rating. The part achieves ROHS3 compliance and is suitable for general purpose, automotive, medical, and telecommunications applications.

Molex 0878910504 (KK254 Series) is an active product supplied in tray packaging. This part shares the same pitch and position configuration as the original part. The extended post length (1.142") distinguishes this variant for applications requiring deeper board penetration. The part achieves ROHS3 compliance and is rated for automotive, general purpose, medical, and telecommunications applications.

Amphenol ICC 68653-105HLF (BERGSTIK® II Series) is an active product supplied in bag packaging. This part maintains the 5-position, 2.54mm pitch header configuration with push-pull fastening. The current rating of 5A exceeds the original part specification of 2.5A. The part achieves RoHS compliance and is suitable for general purpose applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0423751858 be used as a direct replacement for the 3M 926141-01-05-EU?

A: The Molex 0423751858 meets all core substitution criteria: 5-position, 1-row, 2.54mm pitch header with male pins, through-hole solder termination, and push-pull fastening. Variations in contact length and insulation material do not affect functional compatibility in standard board-to-board applications. The part is ROHS3 compliant and active in production.

Q: What is the significance of the extended post length on the Molex 0878910504?

A: The Molex 0878910504 features a post length of 1.142" (29.00mm) compared to 0.100" (2.54mm) on the original part. This extended post length accommodates applications requiring deeper solder joint penetration or extended component standoff from the PCB. The mating interface and pitch geometry remain identical, preserving electrical and mechanical compatibility.

Q: How do contact finish differences affect substitution?

A: The original 3M part specifies gold contact finish on the mating surface. The Molex 0423751858 uses tin finish, while the Molex 0878910504 and Amphenol ICC 68653-105HLF use gold finish. Contact finish composition does not affect mechanical fit or electrical continuity in standard applications. Selection should be based on application-specific corrosion resistance or environmental requirements.

Q: Are there packaging considerations when selecting a substitute?

A: The three substitute parts are supplied in different packaging formats: Molex 0423751858 (bulk), Molex 0878910504 (tray), and Amphenol ICC 68653-105HLF (bag). Packaging selection should align with procurement volume and inventory management requirements. All parts maintain identical connector specifications and are functionally equivalent.

Q: Does the Amphenol ICC 68653-105HLF current rating of 5A provide an advantage over the original 2.5A specification?

A: The Amphenol ICC 68653-105HLF is rated for 5A, which exceeds the original 3M part specification of 2.5A. This higher current rating provides additional design margin for applications operating near the original current limit. The part remains functionally compatible with designs specified for 2.5A operation.

Q: What compliance certifications are relevant for substitute selection?

A: All substitute parts maintain UL94 V-0 flammability rating, matching the original part. The Molex parts achieve ROHS3 compliance, while the Amphenol ICC part achieves RoHS compliance. All parts have MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.
