Equivalent & Substitute Parts for Molex 0039274262

Part Overview

The Molex 0039274262 is a rectangular connector header designed for through-hole mounting with 26 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This connector belongs to the Micro Shunt 5547 series and features unshrouded, male pin contacts with solder termination and push-pull fastening. The product is currently obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0039274262 is determined by strict alignment of the following critical parameters:

• Number of positions: 26
• Number of rows: 2
• Pitch spacing: 0.100" (2.54mm)
• Row spacing: 0.100" (2.54mm)
• Mounting type: Through hole
• Termination method: Solder
• Fastening type: Push-pull
• Shrouding: Unshrouded

Two substitute categories are identified:

Category 1: Direct Header Replacement — Amphenol ICC (FCI) 75844-379-26LF maintains the same connector type (header) with identical pitch, position count, and mounting specifications. This part is active and fully supported.

Category 2: Spring Piston Alternative — Mill-Max Manufacturing Corp. parts 823-22-026-10-003101 and 823-22-026-10-004101 provide functional equivalence through spring piston contact technology. These parts maintain identical pitch, position count, row configuration, and through-hole mounting, offering an alternative contact mechanism while preserving board-level compatibility.

Parameter Comparison

Engineering Selection Recommendations

For direct form-fit-function replacement: The Amphenol ICC 75844-379-26LF is the primary substitute. It maintains active product status, meets RoHS compliance requirements, and preserves the header connector architecture with identical pitch and position specifications. The contact shape difference (square vs. circular) and insulation material variation (thermoplastic vs. PBT glass-filled) do not affect board-level compatibility given the identical mating pitch and position count.

For alternative contact technology: The Mill-Max 823-22-026-10-003101 and 823-22-026-10-004101 spring piston connectors provide functional equivalence through a different contact mechanism. Both parts maintain ROHS3 compliance and MSL 1 rating. The spring piston design offers different mechanical and electrical characteristics compared to the male pin header design. Selection between these alternatives depends on specific application requirements regarding contact force, insertion cycles, and electrical performance parameters not specified in the provided data.

Compliance considerations: All substitute parts maintain RoHS compliance and MSL 1 moisture sensitivity ratings consistent with the original part. The Amphenol ICC part carries RoHS compliance status, while both Mill-Max parts maintain ROHS3 compliance matching the original specification.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 75844-379-26LF be used as a direct replacement for the Molex 0039274262?

A: Yes. Both connectors share identical mating pitch (0.100"), position count (26), row configuration (2 rows), row spacing (0.100"), through-hole mounting, solder termination, and push-pull fastening. The connector is active and fully supported by the manufacturer.

Q: What is the functional difference between the header connector and the spring piston alternatives?

A: The Molex 0039274262 and Amphenol ICC 75844-379-26LF use male pin contacts, while the Mill-Max parts employ spring piston contact technology. Both achieve the same 26-position, 2-row, 0.100" pitch board-level interface. The contact mechanism difference affects insertion force, contact reliability characteristics, and electrical performance parameters not provided in this specification.

Q: Are the Mill-Max 823-22-026-10-003101 and 823-22-026-10-004101 interchangeable with each other?

A: Both Mill-Max parts share identical specifications for position count, pitch, row configuration, mounting type, and termination. They are functionally equivalent for board-level applications requiring 26-position, 2-row, 0.100" pitch spring piston connectors.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts maintain RoHS compliance and MSL 1 (unlimited moisture sensitivity) ratings. The Amphenol ICC part carries RoHS compliance status, while both Mill-Max parts maintain ROHS3 compliance, matching the original Molex part specification.

Q: Does the contact finish difference (tin vs. gold) affect substitution compatibility?

A: Contact finish affects electrical and corrosion resistance characteristics but does not prevent physical or mechanical substitution. The Amphenol ICC part uses tin finish matching the original, while Mill-Max parts use gold finish. Selection should account for application-specific requirements regarding contact resistance and environmental exposure.
