Substitute Part Grouping Explanation

The 3M N3764-6002RB qualifies as a direct substitute for the 3764-6002 based on the following critical parameters:

Connector configuration: Identical 64-position, 2-row header with 0.100" (2.54mm) pitch and row spacing
Mechanical interface: Matching through-hole mounting, shrouded 4-wall design, and push-pull fastening
Electrical performance: Equivalent 1.75A current rating and -55°C ~ 105°C operating temperature range
Contact specifications: Same mating contact length (0.240"), post length (0.112"), and overall contact length (0.652")
Insulation properties: Identical PCT polyester glass-filled material with UL94 V-0 flammability rating
Termination method: Solder termination with matching contact material (copper alloy)

The primary differences are product status (active vs. obsolete), packaging format (bulk vs. standard), insulation color (black vs. beige), post contact finish (tin vs. tin-lead), and RoHS compliance status.

Engineering Selection Recommendations

The N3764-6002RB is the direct active equivalent for the obsolete 3764-6002. Selection of the substitute part is supported by:

Product status alignment: The N3764-6002RB is active and currently in production, ensuring long-term availability and supply chain continuity.
Regulatory compliance: The substitute part is RoHS compliant, meeting current environmental and regulatory requirements for new designs and procurement.
Functional equivalence: All critical electrical and mechanical parameters are identical, ensuring drop-in compatibility in existing applications.
Certification maintenance: Both parts maintain UL94 V-0 flammability rating and identical MSL classification.

The post contact finish change from tin-lead to tin reflects modern manufacturing standards and does not affect electrical performance or mechanical compatibility within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the N3764-6002RB be used as a direct replacement for the 3764-6002 in existing designs?

A: Yes. The N3764-6002RB maintains identical connector configuration, pitch, row spacing, mounting type, shrouding, fastening mechanism, current rating, and operating temperature range. The mechanical and electrical interfaces are fully compatible.

Q: What is the significance of the RoHS compliance difference?

A: The 3764-6002 is RoHS non-compliant due to tin-lead post contact finish. The N3764-6002RB uses tin finish and is RoHS compliant, meeting current regulatory requirements for new production and procurement in most markets.

Q: Does the change from tin-lead to tin post finish affect performance?

A: No. Both finishes provide equivalent electrical conductivity and mechanical performance within the specified 1.75A current rating and -55°C ~ 105°C operating temperature range. The tin finish is standard in current manufacturing.

Q: Are there packaging considerations when switching to the N3764-6002RB?

A: The substitute is supplied in bulk packaging rather than standard packaging. Verify that bulk packaging meets your procurement and handling requirements.

Q: Does the insulation color change from beige to black affect functionality?

A: No. Insulation color is a visual identifier only and does not affect electrical or mechanical performance. Both parts use identical PCT polyester glass-filled material with UL94 V-0 rating.

Q: What is the inventory status for the substitute part?

A: The N3764-6002RB has 1003 pieces in new original stock, providing immediate availability for procurement.
