3M 3428-5302 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 3428-5302 is a through-hole, right-angle rectangular connector header with 20 positions at 2.54mm pitch, designed for board-to-board or cable interconnection applications. This part carries an obsolete product status with 829 units in current inventory. Due to its obsolescence, equivalent substitute parts from active product lines are necessary for ongoing design support and procurement continuity. Substitute options are available from 3M's active series and alternative manufacturers including TE Connectivity and HARTING, all maintaining the core electrical and mechanical specifications required for direct functional replacement.

Engineering Selection Recommendations

3M Direct Equivalents (Recommended for Minimum Design Change):

N3428-5302RB is the direct active-status equivalent to 3428-5302, maintaining identical electrical and mechanical specifications with the addition of ROHS3 compliance. This part is the primary recommendation for applications requiring no design modification. D3428-5002-AR and N3428-5002RB are functionally equivalent alternatives within the 3M product family, differing only in fastening mechanism (Push-Pull versus Latch Lock/Eject Hooks) and contact material (Brass versus Copper Alloy in D3428-5002-AR). Both are ROHS3 compliant and carry active product status.

Cross-Manufacturer Alternatives (TE Connectivity and HARTING):

5499345-4 from TE Connectivity AMP-Latch series provides full electrical and mechanical compatibility with extended operating temperature range (-65°C to 105°C). HARTING SEK series parts (09185205901, 09185205911, 09185205913, 09185206901, 09185206903, 09185206903001) maintain all primary matching criteria with variations in fastening type and contact post length. HARTING parts support extended operating temperature to 125°C and are ROHS3 compliant. Selection among HARTING variants depends on specific fastening mechanism and contact post length requirements for PCB assembly compatibility.

All substitute parts listed carry ROHS3 compliance and active product status, ensuring long-term availability and regulatory alignment for new designs.

Frequently Asked Questions (FAQ)

Q: Can N3428-5302RB be used as a direct replacement for 3428-5302?

A: Yes. N3428-5302RB maintains identical electrical and mechanical specifications including 20 positions, 2.54mm pitch, through-hole right-angle mounting, shrouded 4-wall design, and operating temperature range of -55°C to 105°C. The primary difference is ROHS3 compliance status. No design modification is required.

Q: What is the difference between Latch Lock/Eject Hooks (Long) and Push-Pull fastening types?

A: Fastening type determines the mating connector engagement mechanism. Latch Lock/Eject Hooks (Long) provides mechanical latching with long hook engagement, while Push-Pull uses a simpler push-to-connect, pull-to-disconnect mechanism. Both are functionally equivalent for electrical connection; selection depends on application requirements for connector retention force and ease of mating/unmating.

Q: Are HARTING SEK series parts compatible with 3M 3428-5302?

A: Yes. HARTING 09185205901, 09185205911, 09185205913, 09185206901, 09185206903, and 09185206903001 all meet the primary matching criteria: 20 positions, 2.54mm pitch, through-hole right-angle mounting, shrouded 4-wall design, and UL94 V-0 flammability rating. Variations exist in fastening type and contact post length. HARTING parts support extended operating temperature to 125°C and are ROHS3 compliant.

Q: What is the significance of contact post length variation (0.110" to 0.177")?

A: Contact post length affects PCB assembly compatibility and insertion depth into mating connectors. Shorter post lengths (0.110" to 0.114") are suitable for standard PCB thicknesses, while longer post lengths (0.177") accommodate thicker PCBs or specific assembly requirements. Selection must align with PCB thickness and mating connector specifications.

Q: Does packaging type (Bulk versus Tray) affect electrical or mechanical performance?

A: No. Packaging type (Bulk or Tray) is a logistics and handling consideration only and does not affect electrical or mechanical performance. Selection depends on procurement volume and inventory management requirements.

Q: Why is RoHS compliance status different between 3428-5302 and its substitutes?

A: The original 3428-5302 is RoHS non-compliant due to its obsolete status and tin-lead post finish. Active substitute parts including N3428-5302RB, 3M D3428 series, TE Connectivity 5499345-4, and HARTING SEK series are ROHS3 compliant, reflecting current regulatory requirements and manufacturing standards. For new designs, ROHS3-compliant parts are recommended.

Q: Can TE Connectivity 5499345-4 be used in applications requiring -55°C minimum operating temperature?

A: Yes. TE Connectivity 5499345-4 supports operating temperature range of -65°C to 105°C, which exceeds the -55°C to 105°C requirement of 3428-5302. This part is suitable for applications requiring extended low-temperature performance.
