3M D3428-6002-AR Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M D3428-6002-AR is an active rectangular connector header designed for through-hole mounting applications. This 20-position, 2-row connector operates within the D3000 series and provides board-to-cable/wire connectivity with push-pull fastening. The connector is manufactured from brass with gold-plated mating contacts and tin-plated posts, rated for 1.75A continuous current across an operating temperature range of -55°C to 105°C. Substitute parts are identified to address inventory availability, packaging preferences, fastening mechanism variations, and alternative manufacturer options while maintaining core electrical and mechanical compatibility.

Engineering Selection Recommendations

All identified substitute parts maintain active product status and comply with RoHS regulations. The D3428-6202-AR and D3428-6302-AR variants differ from the primary part only in fastening mechanism—short latch lock/eject hooks and long latch lock/eject hooks respectively—while maintaining identical electrical and mechanical specifications. Selection between these 3M variants depends on connector retention requirements within the application.

The N3428-6002RB provides equivalent functionality with push-pull fastening identical to the primary part but differs in contact material composition (copper alloy versus brass) and contact finish thickness specifications. This part is available in bulk packaging rather than tray format.

The 71918-020LF from Amphenol ICC (FCI) represents a cross-manufacturer alternative within the Quickie™ series. This part maintains core electrical compatibility but exhibits minor dimensional variations in contact length and insulation height, along with different insulation material composition and color specification. Operating temperature and current rating specifications are not provided for this part.

The D3428-6302-AR offers the highest inventory availability at 20,300 pieces, supporting applications requiring extended lead time assurance.

Frequently Asked Questions (FAQ)

Q: Can D3428-6202-AR and D3428-6302-AR be used interchangeably with D3428-6002-AR?

A: Yes, within the constraints of fastening mechanism compatibility. The D3428-6202-AR features short latch lock/eject hooks, while the D3428-6302-AR features long latch lock/eject hooks. The primary part D3428-6002-AR uses push-pull fastening. Connector retention force and mating/unmating procedures differ between these fastening types. Verify that the application's connector retention requirements align with the selected fastening mechanism.

Q: What are the key differences between 3M and Amphenol ICC (FCI) options?

A: The 3M D3000 series parts (D3428-6002-AR, D3428-6202-AR, D3428-6302-AR) and the 3M N3428-6002RB maintain consistent specifications within the 3M product family. The Amphenol ICC (FCI) 71918-020LF Quickie™ series part provides cross-manufacturer compatibility but includes minor dimensional variations in contact length (0.228" versus 0.240") and insulation height (0.685" versus 0.680"), along with different contact material (phosphor bronze versus brass) and insulation material composition (thermoplastic versus PCT polyester). These variations remain within acceptable tolerance for standard 0.100" (2.54mm) pitch header applications.

Q: Does packaging format affect electrical or mechanical performance?

A: No. Tray, bulk, and tube packaging formats do not affect connector electrical or mechanical performance. Packaging selection depends on assembly process requirements, inventory management practices, and handling procedures. The D3428-6002-AR and D3428-6202-AR are supplied in tray format, the D3428-6302-AR in tray format, the N3428-6002RB in bulk format, and the 71918-020LF in tube format.

Q: Are contact finish thickness variations significant for this application?

A: Contact finish thickness variations are provided as specified parameters. The D3428-6002-AR specifies 10.0µin (0.25µm) mating finish thickness and 39.4µin (1.00µm) post finish thickness. The N3428-6002RB specifies 30.0µin (0.76µm) mating finish thickness and 200.0µin (5.08µm) post finish thickness. The 71918-020LF specifies 30.0µin (0.76µm) mating finish thickness and 78.7µin (2.00µm) post finish thickness. These variations reflect different manufacturing specifications and should be evaluated against specific application requirements for contact durability and wear resistance.

Q: What is the significance of ROHS3 compliance versus RoHS compliance?

A: Both designations indicate RoHS directive compliance. ROHS3 represents compliance with the most recent RoHS 3 directive (2011/65/EU as amended by 2015/863/EU), which includes restrictions on phthalates in addition to the original restricted substances. RoHS Compliant indicates compliance with the original RoHS directive. Both are acceptable for applications requiring RoHS compliance; ROHS3 compliance provides alignment with current regulatory standards.
