3428-5202-UG Equivalent & Substitute Parts

Part Overview

The 3M 3428-5202-UG is a rectangular connector header, right-angle configuration, with 20 positions at 2.54mm pitch. This through-hole component features shrouded 4-wall design with solder termination and latch lock/eject hook fastening. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the 3428-5202-UG is determined by the following critical parameters:

Connector type (Header) and contact type (Male Pin)
Position count (20) and row configuration (2 rows)
Mating pitch (0.100" / 2.54mm) and row spacing (0.100" / 2.54mm)
Mounting method (Through Hole, Right Angle)
Shrouding configuration (Shrouded - 4 Wall)
Termination method (Solder)
Operating temperature range (-55°C ~ 105°C minimum)
Flammability rating (UL94 V-0)

All three substitute parts meet these core electrical and mechanical requirements. Variations in fastening type (latch lock versus push-pull), contact material composition, contact finish specifications, and RoHS compliance status do not preclude functional substitution when these parameters remain within acceptable tolerances for the application.

Engineering Selection Recommendations

All three substitute parts satisfy the core electrical and mechanical requirements of the 3428-5202-UG. Selection among alternatives depends on specific application constraints:

D3428-5002-AR (3M, Active): This 3M part maintains manufacturer continuity and is actively produced. It features push-pull fastening instead of latch lock configuration and supports higher current rating (1.75A versus 1A). ROHS3 compliance is achieved. Packaging is supplied in trays.

N3428-5002RB (3M, Active): Also from 3M with active production status, this variant uses push-pull fastening and supports 1.75A current rating. ROHS3 and REACH compliance are confirmed. Bulk packaging is standard for this part number.

2-5499345-4 (TE Connectivity, Active): This cross-manufacturer alternative from TE Connectivity AMP Connectors series maintains latch lock fastening identical to the original part. Extended operating temperature range (-65°C minimum) provides additional thermal margin. ROHS3 and REACH compliance are confirmed. Tray packaging is provided. Insulation height is 0.315" (8.00mm), which is 0.025" lower than the 3M alternatives.

For applications requiring exact fastening mechanism preservation, 2-5499345-4 is the preferred substitute. For applications where fastening type flexibility exists, either 3M alternative (D3428-5002-AR or N3428-5002RB) provides continued manufacturer support with improved current capacity and modern compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can D3428-5002-AR replace 3428-5202-UG directly?

A: D3428-5002-AR meets all core electrical and mechanical specifications. The primary difference is fastening type: push-pull versus latch lock. If the mating connector is designed for push-pull engagement, direct substitution is valid. If the design requires latch lock fastening, mechanical compatibility must be verified.

Q: What is the significance of the current rating increase from 1A to 1.75A in the 3M substitutes?

A: The higher current rating in D3428-5002-AR and N3428-5002RB indicates improved contact design and material composition. These parts can safely carry higher current loads. For applications operating at or near the original 1A specification, this increase provides additional design margin and reliability.

Q: Are there packaging differences between the substitute parts?

A: Yes. D3428-5002-AR is supplied in trays, N3428-5002RB in bulk, and 2-5499345-4 in trays. Packaging selection affects procurement, handling, and storage procedures but does not impact electrical or mechanical performance.

Q: Why does 2-5499345-4 have a lower insulation height?

A: The TE Connectivity part specifies 0.315" (8.00mm) insulation height compared to 0.340" (8.64mm) for the 3M alternatives. This 0.025" difference reflects different mechanical design approaches. PCB layout and mating connector clearances must accommodate this dimensional variation.

Q: Which substitute is recommended for new designs?

A: For new designs, any of the three active parts are acceptable. D3428-5002-AR or N3428-5002RB maintain 3M manufacturer continuity with ROHS3 compliance. 2-5499345-4 provides cross-manufacturer diversity and extended temperature range. Selection should align with existing supply chain relationships and design requirements.

Q: Are all substitutes RoHS compliant?

A: The original 3428-5202-UG is RoHS non-compliant. All three substitutes are ROHS3 compliant, meeting current environmental regulations. This compliance improvement is a key advantage of transitioning to active production alternatives.
