3M 4620-7200 Rectangular Connector Plug - Equivalent & Substitute Parts

Part Overview

The 3M 4620-7200 is a 20-position rectangular plug connector with IDC (Insulation Displacement Contact) termination, designed for discrete or ribbon cable applications with wire gauges of 26-28 AWG. This connector features gold-plated contacts, a closed-end design, and latch lock/eject hook fastening. The part is Active status and ROHS3 compliant, making it suitable for applications requiring reliable in-line connectivity with secure mechanical retention.

Substitute parts are identified when electrical and mechanical parameters remain equivalent, enabling component interchangeability in circuit designs and assemblies without functional degradation.

Substitute Part Grouping Explanation

Substitute parts for the 3M 4620-7200 are qualified based on the following critical parameters that determine functional equivalence:

Connector geometry: 20 positions, 0.100" (2.54mm) pitch, 2-row configuration with 0.100" row spacing
Electrical interface: Male pin contact type with gold plating at 30.0µin thickness
Termination method: IDC cable termination supporting 26-28 AWG wire (stranded or solid)
Mechanical mounting: Free hanging in-line configuration
Environmental compliance: ROHS3 compliance and MSL 1 rating

The identified substitutes (4620-6000 and 4620-6200) maintain these core parameters. Variations in fastening type (latch lock/eject hooks versus feed-through design) and end configuration (closed-end versus feed-through) represent mechanical design differences that do not affect electrical compatibility when mated with corresponding receptacle connectors.

Engineering Selection Recommendations

All three parts (4620-7200, 4620-6000, and 4620-6200) are Active status products with ROHS3 compliance and identical electrical specifications. Selection between these parts should be based on mechanical design requirements:

4620-7200: Closed-end design with latch lock/eject hook fastening. Select when mechanical retention and sealed end configuration are required.
4620-6000: Feed-through design without fastening specification. Select when open-end geometry and minimal mechanical constraints are acceptable.
4620-6200: Feed-through design with latch lock/eject hook fastening. Select when feed-through geometry combined with mechanical retention is required.

All parts support identical wire gauges (26-28 AWG), IDC termination, and gold contact finish specifications. Inventory availability: 4620-7200 (972 pcs), 4620-6000 (2727 pcs), 4620-6200 (1224 pcs).

Frequently Asked Questions (FAQ)

Q: Can 4620-6000 be used as a direct replacement for 4620-7200?

A: Electrical compatibility is maintained. The primary difference is the feed-through end configuration versus closed-end design. Mechanical fit depends on the receptacle connector and assembly constraints. Verify fastening requirements in your application.

Q: What is the difference between closed-end and feed-through designs?

A: Closed-end (4620-7200) provides a sealed connector end. Feed-through (4620-6000, 4620-6200) allows wire passage through the connector body. Selection depends on assembly geometry and cable routing requirements.

Q: Are all three parts compatible with the same receptacle connectors?

A: Yes. All three parts maintain identical contact pitch (0.100"), row spacing (0.100"), and male pin contact geometry. Compatibility with receptacle connectors is determined by these electrical and mechanical parameters, which are equivalent across all three parts.

Q: What wire gauges are supported?

A: All three parts support 26-28 AWG wire in both stranded and solid configurations using IDC termination.

Q: Do these parts require special handling or storage?

A: All three parts have MSL 1 rating (Unlimited), indicating no moisture sensitivity restrictions. Standard component storage practices apply.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant, meeting current environmental and regulatory requirements.
