3M 3372-6305 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 3372-6305 is an active rectangular connector header designed for through-hole board-to-board or cable applications. This 60-position, 2-row vertical header operates across -55°C to 105°C and features shrouded 4-wall construction with wire wrap termination. The part is RoHS compliant and carries UL94 V-0 flammability rating. Substitute parts are identified when equivalent electrical and mechanical parameters align with application requirements, enabling component sourcing flexibility while maintaining circuit performance and reliability standards.

Key Parameters

Substitute Part Grouping Explanation

The 3M N3372-6002RB qualifies as a substitute for the 3372-6305 based on alignment of critical electrical and mechanical parameters. Both parts share identical specifications for connector type (header), contact type (male pin), position count (60), row configuration (2 rows), mating pitch (0.100"/2.54mm), row spacing (0.100"/2.54mm), mounting method (through hole), shrouding style (shrouded 4-wall), operating temperature range (-55°C to 105°C), contact material (copper alloy), mating contact finish (gold), flammability rating (UL94 V-0), and compliance certifications (RoHS compliant, MSL 1).

Differences exist in termination method (wire wrap versus solder), fastening type (latch lock/eject hooks versus push-pull), contact post length, insulation material composition (PBT polyester versus PCT polyester), and current rating (1A versus 1.75A). These variations do not preclude substitution when application requirements accommodate the alternative termination and fastening approaches.

Parameter Comparison

Engineering Selection Recommendations

Both the 3372-6305 and N3372-6002RB are active products from 3M's 3000 series with identical compliance certifications. Selection between these parts depends on termination methodology and circuit board assembly process. The 3372-6305 with wire wrap termination suits applications requiring post-insertion into wire wrap sockets. The N3372-6002RB with solder termination integrates directly into printed circuit board pads through standard reflow or wave soldering processes. The N3372-6002RB provides higher current capacity (1.75A versus 1A), which may be advantageous in higher-current applications. Both parts maintain RoHS compliance, UL94 V-0 flammability rating, and unlimited moisture sensitivity classification, ensuring regulatory and environmental compatibility across industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: What determines whether N3372-6002RB can substitute for 3372-6305?

A: Substitution is valid when the connector maintains identical electrical and mechanical interface specifications: 60 positions, 2 rows, 0.100" (2.54mm) pitch, through-hole mounting, shrouded 4-wall construction, and operating temperature range of -55°C to 105°C. Both parts meet these criteria.

Q: How do termination differences affect substitution?

A: The 3372-6305 uses wire wrap termination for insertion into wire wrap sockets, while N3372-6002RB uses solder termination for direct PCB mounting. Substitution requires that the receiving circuit board design accommodates the alternative termination method. Wire wrap and solder termination are not interchangeable on the same board layout.

Q: Are the contact post lengths compatible?

A: No. The 3372-6305 has a 0.610" (15.49mm) post length, while N3372-6002RB has a 0.112" (2.84mm) post length. This difference reflects their distinct termination methods and is not a compatibility issue when each part is used with its intended termination approach.

Q: Does the higher current rating of N3372-6002RB affect compatibility?

A: The N3372-6002RB current rating of 1.75A exceeds the 3372-6305 rating of 1A. This represents a capability advantage and does not create compatibility issues. Applications designed for 1A operation remain compatible with the higher-rated substitute.

Q: Are both parts RoHS compliant?

A: Yes. Both 3372-6305 and N3372-6002RB are RoHS compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: What is the difference between PBT and PCT insulation materials?

A: The 3372-6305 uses polybutylene terephthalate (PBT) insulation, while N3372-6002RB uses polycyclohexylenedimethylene terephthalate (PCT) insulation. Both are polyester-based, glass-filled materials with UL94 V-0 flammability rating. This material difference does not affect electrical or mechanical compatibility for standard applications.

Q: Can these parts be used interchangeably in existing designs?

A: Interchangeability requires that the circuit board or assembly design accommodates the specific termination method of the selected part. Wire wrap and solder termination require different board layouts and assembly processes. Electrical and mechanical interface compatibility is confirmed, but physical integration method must align with the chosen part's termination approach.
