3M 3764-6302 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The 3M 3764-6302 is a vertical through-hole rectangular connector header with 64 positions at 2.54mm pitch, designed for board-to-cable/wire applications. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The connector features shrouded 4-wall construction with latch lock/eject hooks and gold-plated mating contacts suitable for 1A current applications across the -55°C to 105°C operating temperature range.

Substitute Part Grouping Explanation

Substitution for the 3M 3764-6302 is determined by strict equivalence across the following critical parameters:

Connector type (Header), contact type (Male Pin), and configuration (64 positions, 2 rows)
Pitch and row spacing (0.100" / 2.54mm)
Mounting method (Through Hole, vertical orientation)
Shrouding style (Shrouded - 4 Wall)
Fastening mechanism (Latch Lock/Eject Hooks)
Contact finish specifications (Gold mating, Tin or Tin-Lead post)
Operating temperature range (-55°C to 105°C minimum)
Flammability rating (UL94 V-0)

Substitute parts must maintain electrical and mechanical compatibility across all these parameters. Parts with differing position counts, pitch specifications, or mounting orientations are not considered direct substitutes.

Engineering Selection Recommendations

Primary Substitute: 3M N3764-6302RB

The 3M N3764-6302RB is the direct manufacturer upgrade from the obsolete 3764-6302. It maintains identical mechanical and electrical specifications while offering RoHS compliance and improved current rating (1.75A vs. 1A). This part is the preferred choice for direct replacement in new designs and production runs.

Secondary Substitutes: TE Connectivity AMP-Latch Series

The TE Connectivity parts (1-5102321-2, 1-5499206-2, 1-5499922-2, 1-5499923-2) provide full mechanical and electrical compatibility with the original 3M 3764-6302. These parts are active products with extended operating temperature range (-65°C to 105°C) and are available in RoHS3-compliant variants. Selection among TE Connectivity options depends on specific compliance requirements and packaging preferences.

Compliance Considerations:

For RoHS-compliant applications, select 3M N3764-6302RB, TE 1-5102321-2, TE 1-5499206-2, or TE 1-5499923-2
For ROHS3 compliance, select TE 1-5499206-2 or TE 1-5499923-2
For REACH-unaffected applications, select 3M N3764-6302RB or TE Connectivity parts with REACH Unaffected status

Frequently Asked Questions (FAQ)

Q: Can the 3M N3764-6302RB directly replace the obsolete 3M 3764-6302?

A: Yes. The N3764-6302RB maintains identical pitch (2.54mm), position count (64), row configuration (2 rows), mounting type (through hole), shrouding (4-wall), and fastening mechanism (latch lock/eject hooks). The primary differences are RoHS compliance and increased current rating (1.75A), both of which are improvements for the original application.

Q: What are the key differences between 3M and TE Connectivity substitutes?

A: Both manufacturers provide mechanically and electrically compatible 64-position, 2.54mm pitch headers. TE Connectivity parts offer extended operating temperature range (-65°C vs. -55°C minimum) and 250VAC voltage rating specification. Selection depends on compliance requirements, packaging format, and inventory availability.

Q: Are TE Connectivity AMP-Latch parts interchangeable with each other?

A: The TE Connectivity parts 1-5102321-2, 1-5499206-2, 1-5499922-2, and 1-5499923-2 are mechanically and electrically interchangeable. Differences exist in contact post length (0.110" vs. 0.155"), contact finish thickness on mating surfaces (15.0µin vs. 30.0µin), and RoHS compliance status. These variations do not affect functional compatibility in standard applications.

Q: What packaging options are available for substitutes?

A: The 3M N3764-6302RB is supplied in bulk packaging. TE Connectivity parts are available in tray or bulk packaging depending on the specific part number. Packaging selection should align with production workflow and inventory management requirements.

Q: Does contact finish thickness affect compatibility?

A: Contact finish thickness variations (15.0µin, 30.0µin) do not affect mechanical or electrical compatibility. These specifications relate to durability and mating cycle life but do not impact functional interchangeability in standard connector applications.
