3M 926141-01-36-I Equivalent & Substitute Parts

Part Overview

The 3M 926141-01-36-I is a rectangular connector header designed for through-hole board-to-board applications. This 36-position connector operates at 0.100" (2.54mm) pitch and features gold-plated male pins with solder termination. The part is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution of the 3M 926141-01-36-I is determined by the following critical parameters:

36-position configuration with 0.100" (2.54mm) pitch spacing
Male pin contact type for header applications
Through-hole solder termination
Board-to-board connection style
Unshrouded design
UL94 V-0 flammability compliance

The Amphenol ICC (FCI) 77311-832-36LF meets these core substitution criteria. Both connectors share identical position count, pitch, contact type, mounting method, and termination approach, enabling direct functional replacement in applications requiring 36-position 2.54mm pitch headers.

Engineering Selection Recommendations

The Amphenol ICC 77311-832-36LF is the active equivalent for the obsolete 3M 926141-01-36-I. Selection between these parts should be based on the following factors:

Product Status: The 3M part is obsolete. The Amphenol ICC part maintains active production status, ensuring long-term availability and supply chain continuity.

Compliance & Certifications: Both connectors meet UL94 V-0 flammability requirements and carry identical ECCN and HTSUS classifications. The Amphenol ICC part includes RoHS Compliance and REACH Affected status documentation.

Electrical Performance: The Amphenol ICC substitute provides higher current rating (3A per contact versus 2.5A) and extended operating temperature range (-65°C ~ 125°C versus -40°C ~ 105°C), offering improved performance margins for demanding applications.

Physical Compatibility: Contact length variations are minimal (0.02" difference in mating length, 0.02" difference in post length). Overall contact length remains functionally equivalent at 0.626" versus 0.628". These dimensional differences do not affect board-level compatibility for standard through-hole applications.

Material Differences: The substitute uses phosphor bronze contacts with tin post finish versus copper alloy with gold post finish on the original. These material changes maintain electrical performance while supporting active production economics.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 77311-832-36LF directly replace the 3M 926141-01-36-I in existing designs?

A: Yes. Both connectors share identical 36-position configuration, 0.100" (2.54mm) pitch, male pin contact type, through-hole mounting, and solder termination. Physical dimensions are functionally equivalent for board-level applications. The substitute provides equal or superior electrical performance.

Q: What are the key differences between these two connectors?

A: Primary differences include product status (obsolete versus active), contact material (copper alloy versus phosphor bronze), post finish (gold versus tin), operating temperature range (-40°C ~ 105°C versus -65°C ~ 125°C), and current rating (2.5A versus 3A per contact). Contact length variations are minor and do not affect standard through-hole board compatibility.

Q: Does the Amphenol ICC part meet the same compliance standards?

A: Yes. Both connectors meet UL94 V-0 flammability requirements and carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications. The Amphenol ICC part additionally documents RoHS Compliance and REACH Affected status.

Q: Are there packaging differences between these parts?

A: The 3M part packaging is not specified in available documentation. The Amphenol ICC part is supplied in bag packaging. Confirm packaging requirements with your procurement team.

Q: What is the impact of the contact finish difference?

A: The original uses gold-plated contacts on both mating and post surfaces. The substitute uses gold or gold GXT™ on mating surfaces with tin post finish. Both finishes support solder termination and maintain electrical performance for standard board-to-board applications.

Q: Should I consider the extended temperature range of the substitute?

A: The Amphenol ICC part operates from -65°C ~ 125°C compared to -40°C ~ 105°C for the original. If your application operates within the original temperature range, both parts are suitable. The extended range on the substitute provides additional design margin for temperature-sensitive environments.
