3M 3428-5602UG Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 3428-5602UG 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 is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production support. The connector features shrouded 4-wall construction with gold-plated mating contacts and tin-lead post finish, operating across the -55°C to 105°C temperature range with UL94 V-0 flammability rating.

Substitute Part Grouping Explanation

Substitution eligibility for the 3428-5602UG is determined by strict alignment across the following critical parameters: connector type (header), contact type (male pin), position count (20), row configuration (2 rows), mating pitch (2.54mm), row spacing (2.54mm), mounting method (through-hole right-angle), shrouding style (shrouded 4-wall), contact shape (square), mating contact length (6.10mm), insulation height (8.64mm), contact finish on mating surface (gold), insulation material (PCT polyester glass-filled), features (keying slot and mounting flange), operating temperature range (-55°C to 105°C), flammability rating (UL94 V-0), and insulation color (black).

Substitute parts are grouped into two categories based on fastening mechanism variation:

Category 1: Push-Pull Fastening — Parts D3428-5002-AR and N3428-5002RB employ push-pull fastening instead of the original latch lock/eject hooks. These parts maintain all critical electrical and mechanical parameters while offering improved ease of connection/disconnection.

Category 2: Latch Lock/Eject Hooks Fastening — Parts 102322-4, 2-5499141-4, 499141-4, and 5102322-4 retain the original latch lock/eject hooks fastening mechanism. These parts are sourced from TE Connectivity AMP Connectors series and maintain functional equivalence with the original design.

Engineering Selection Recommendations

For RoHS3 Compliant Applications: Select D3428-5002-AR, N3428-5002RB, 2-5499141-4, or 5102322-4. These parts meet ROHS3 compliance requirements and are actively manufactured. D3428-5002-AR and N3428-5002RB offer the additional benefit of increased current rating (1.75A versus 1A), providing design margin for power distribution applications.

For Latch Lock/Eject Hooks Retention: If the original fastening mechanism must be preserved, select from 102322-4, 2-5499141-4, 499141-4, or 5102322-4. All maintain the latch lock/eject hooks fastening type. Among these, 2-5499141-4 and 5102322-4 are ROHS3 compliant.

For Extended Temperature Range: TE Connectivity parts (102322-4, 2-5499141-4, 499141-4, 5102322-4) operate from -65°C to 105°C, providing 10°C additional low-temperature margin compared to the original -55°C to 105°C specification.

For Push-Pull Fastening Preference: D3428-5002-AR and N3428-5002RB employ push-pull fastening, offering simplified connection/disconnection cycles. D3428-5002-AR is packaged in trays; N3428-5002RB is supplied in bulk.

Frequently Asked Questions (FAQ)

Q: Can I use D3428-5002-AR as a direct replacement for 3428-5602UG?

A: D3428-5002-AR is functionally equivalent across all critical electrical and mechanical parameters. The primary difference is the fastening mechanism: D3428-5002-AR uses push-pull fastening instead of latch lock/eject hooks. If your application accommodates push-pull fastening, this part is suitable. D3428-5002-AR also provides higher current rating (1.75A versus 1A) and ROHS3 compliance.

Q: What is the difference between the 3M substitute parts and TE Connectivity parts?

A: Both 3M parts (D3428-5002-AR and N3428-5002RB) and TE Connectivity parts (102322-4, 2-5499141-4, 499141-4, 5102322-4) maintain the same connector pitch, position count, and mounting configuration. The 3M parts feature push-pull fastening and higher current rating. TE Connectivity parts retain latch lock/eject hooks fastening and offer extended temperature range (-65°C to 105°C). Selection depends on fastening preference and compliance requirements.

Q: Are all substitute parts RoHS compliant?

A: No. D3428-5002-AR, N3428-5002RB, 2-5499141-4, and 5102322-4 are ROHS3 compliant. Parts 102322-4 and 499141-4 are RoHS non-compliant. The original 3428-5602UG is also RoHS non-compliant. For new designs requiring RoHS compliance, select from the ROHS3 compliant options.

Q: What packaging options are available?

A: D3428-5002-AR is supplied in trays. N3428-5002RB is supplied in bulk. TE Connectivity parts 102322-4, 2-5499141-4, 499141-4, and 5102322-4 are available in tray or bulk packaging depending on the specific part number.

Q: Can I mix substitute parts in the same assembly?

A: All substitute parts are mechanically and electrically compatible with each other due to identical pitch, position count, and mating contact dimensions. However, fastening mechanism differences (push-pull versus latch lock/eject hooks) should be considered for assembly consistency and operator training.

Q: What is the current rating difference, and does it matter?

A: D3428-5002-AR and N3428-5002RB are rated for 1.75A per contact, while the original 3428-5602UG and TE Connectivity parts are rated for 1A per contact. The higher rating in 3M parts provides additional design margin for power distribution applications but does not prevent use in lower-current applications.
