3M 3627-6602UG Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 3627-6602UG is a shrouded rectangular connector header designed for through-hole mounting in board-to-cable/wire applications. This 24-position, 2-row connector with 0.100" (2.54mm) pitch provides male pin contacts with gold-plated mating surfaces and tin-lead plated posts. The part is classified as obsolete, making identification of active equivalent and substitute parts essential for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution of the 3627-6602UG is determined by strict equivalence across the following critical parameters:

Connector type (Header), contact type (Male Pin), and mating interface (24 positions, 2 rows, 0.100" pitch)
Physical form factor (shrouded 4-wall design, through-hole mounting, solder termination)
Environmental performance (operating temperature -55°C ~ 105°C, UL94 V-0 flammability rating, MSL 1)
Electrical performance (current rating and contact finish specifications)

The substitute parts D3627-6002-AR and N3627-6002RB maintain these core functional parameters while differing in fastening mechanism, contact material composition, insulation material, and regulatory compliance status.

Engineering Selection Recommendations

The 3627-6602UG is obsolete and no longer in active production. Both substitute parts maintain functional and dimensional equivalence for board-to-cable/wire connector applications requiring 24-position, 2-row, 0.100" pitch headers with through-hole solder termination.

D3627-6002-AR is classified as active and RoHS compliant, representing the manufacturer's current-generation equivalent within the D3000 series. This part features push-pull fastening, brass contact material, and PCT insulation material. The higher current rating of 1.75A exceeds the original 1A specification.

N3627-6002RB is classified as active and RoHS compliant within the original 3000 series. This part maintains copper alloy contact material consistent with the original design while incorporating push-pull fastening and PCT insulation material. The current rating of 1.75A also exceeds the original specification.

Selection between D3627-6002-AR and N3627-6002RB depends on design requirements regarding series continuity, contact material composition, and fastening mechanism preference. Both parts satisfy environmental performance, flammability, and moisture sensitivity requirements equivalent to the original part.

Frequently Asked Questions (FAQ)

Q: Can D3627-6002-AR and N3627-6002RB be used interchangeably with 3627-6602UG?

A: Both substitute parts maintain equivalent mating interface geometry (24 positions, 2 rows, 0.100" pitch), shrouding configuration, through-hole mounting, and solder termination. Functional substitution is supported. Physical differences in fastening mechanism (push-pull versus latch lock/eject hooks) and contact material composition must be evaluated against specific application requirements.

Q: What is the difference between the fastening types?

A: The original 3627-6602UG uses latch lock/eject hooks with long engagement. Both substitute parts use push-pull fastening. This affects mating and unmating force characteristics and connector handling procedures. Mechanical compatibility with mating connectors must be verified.

Q: Why do the substitute parts have higher current ratings?

A: D3627-6002-AR and N3627-6002RB are rated for 1.75A compared to the original 1A rating. This reflects updated design specifications and does not indicate incompatibility. Applications designed for 1A operation remain fully supported.

Q: What is the significance of RoHS compliance?

A: The original 3627-6602UG is RoHS non-compliant due to tin-lead plating on posts. Both substitute parts are RoHS compliant, utilizing tin plating on posts and meeting current environmental regulations. This is relevant for applications subject to RoHS requirements.

Q: How do the insulation materials differ?

A: The original part uses PBT (Polybutylene Terephthalate) insulation. Both substitute parts use PCT (Polycyclohexylenedimethylene Terephthalate) insulation. Both materials are polyester-based, glass-filled, and rated UL94 V-0. PCT offers improved thermal and chemical resistance characteristics.

Q: Are there packaging differences?

A: The original 3627-6602UG packaging is not specified. Both substitute parts are supplied in trays. Packaging format should be confirmed with procurement requirements.
