926141-01-29-EU Equivalent & Substitute Parts

Part Overview

The 926141-01-29-EU is a rectangular connector header manufactured by 3M, designed for through-hole board-to-board applications with 29 positions at 0.100" (2.54mm) pitch. This connector features a single-row, unshrouded configuration with male pins and push-pull fastening. The part is classified as obsolete, making identification of equivalent substitute components essential for ongoing design support and procurement continuity.

Engineering Selection Recommendations

The 68604-429HLF serves as the primary substitute for the obsolete 926141-01-29-EU. The substitute part is currently in active production status, ensuring long-term availability and supply chain stability. Both components maintain identical UL94 V-0 flammability ratings and MSL classifications, supporting equivalent reliability in standard operating environments.

The substitute part demonstrates an extended operating temperature range (-65°C ~ 125°C versus -40°C ~ 105°C) and higher current rating (3A versus 2.5A), providing enhanced performance margins in thermal and electrical stress conditions. Contact finish differences (tin versus gold) and minor dimensional variations in contact length do not preclude functional substitution in standard board-to-board interconnect applications where the original specification was met.

Frequently Asked Questions (FAQ)

Q: Can the 68604-429HLF directly replace the 926141-01-29-EU in existing designs?

A: Yes. Both connectors share identical pitch (0.100"), position count (29), row configuration (1), contact type (male pin), mounting method (through hole), and fastening mechanism (push-pull). The mechanical and electrical interfaces are compatible for board-to-board applications.

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

A: Primary differences include contact finish material (gold versus tin), contact material composition (copper alloy versus phosphor bronze), and minor contact length variations. The substitute part offers extended temperature range and higher current capacity. These differences do not affect mechanical mating or standard electrical performance.

Q: Does the contact finish difference impact compatibility?

A: Contact finish differences do not prevent mechanical mating or electrical connection. Both gold and tin finishes provide adequate conductivity for standard signal and power distribution applications. Material selection should be evaluated based on specific application requirements for corrosion resistance or contact wear characteristics.

Q: Are there packaging considerations when sourcing the substitute part?

A: The 68604-429HLF is supplied in bag packaging, whereas the original part packaging specification was not provided. Verify packaging requirements for your procurement and assembly processes.

Q: What compliance certifications apply to the substitute part?

A: The 68604-429HLF maintains UL94 V-0 flammability rating, MSL 1 classification, and EAR99 export control status. The part is RoHS Compliant and REACH Unaffected, supporting compliance with current environmental and regulatory standards.
