Engineering Selection Recommendations

The 3M 81040-600C01-RB-WF is classified as obsolete. The manufacturer-recommended equivalent is the 3M 81040-600C01-RB-WF, which maintains identical specifications across all electrical, mechanical, and environmental parameters.

For applications requiring this connector header, the recommended part maintains full compliance with RoHS directives and UL94 V-0 flammability standards. The connector is suitable for operating environments spanning -55°C to 105°C with a current capacity of 0.75A per contact.

Selection of equivalent parts must prioritize exact parameter matching, particularly for the 0.050" (1.27mm) pitch, 40-position, 2-row configuration with shrouded 4-wall construction and push-pull fastening mechanism.

Frequently Asked Questions (FAQ)

Q: What makes a connector a valid substitute for the 3M 81040-600C01-RB-WF?

A: A substitute connector must match all mandatory parameters: 40 positions in 2 rows, 0.050" (1.27mm) mating pitch, 0.100" (2.54mm) row spacing, surface mount configuration, shrouded 4-wall design, solder termination, and push-pull fastening. Additionally, it must meet or exceed the performance specifications including -55°C to 105°C operating temperature, 0.75A current rating, gold mating contact finish, tin post finish, LCP insulation material, UL94 V-0 flammability rating, and RoHS compliance.

Q: Why is the product status listed as obsolete?

A: Obsolete status indicates the part is no longer in active production by the manufacturer. This necessitates identification of equivalent alternatives for procurement and design continuity in applications currently utilizing this connector.

Q: Are there compatibility concerns when substituting this connector?

A: Substitution is compatible only when all mandatory mechanical and electrical parameters are matched. The 0.050" (1.27mm) pitch and 2-row configuration are critical for mating interface compatibility. Any deviation in these parameters will result in incompatibility with existing mating connectors and PCB layouts.

Q: What is the significance of the shrouded 4-wall construction?

A: The shrouded 4-wall design provides mechanical protection and alignment guidance during mating operations. This feature is integral to the connector's form factor and must be maintained in any substitute part to ensure proper insertion and contact engagement.

Q: Does this connector meet current environmental and compliance standards?

A: The 3M 81040-600C01-RB-WF is RoHS compliant and carries a UL94 V-0 flammability rating, meeting current environmental and safety standards for electronic component applications.
