3M 3372-2002 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 3372-2002 is a vertical rectangular connector header designed for through-hole mounting applications. This 60-position, 2-row connector operates at 0.100" (2.54mm) pitch and supports board-to-board or cable connections with push-pull fastening. The part is classified as obsolete, making identification of active equivalent components essential for ongoing design support and procurement.

Substitute Part Grouping Explanation

The N3372-6002RB serves as a direct functional equivalent to the 3372-2002 based on the following critical parameters:

Connector geometry: Identical 60-position, 2-row configuration with 0.100" (2.54mm) pitch and row spacing
Mounting and termination: Matching through-hole solder termination and push-pull fastening mechanism
Electrical performance: Both support 0.100" (2.54mm) mating pitch with square copper alloy contacts
Environmental rating: Identical operating temperature range of -55°C ~ 105°C and UL94 V-0 flammability classification
Mechanical compatibility: Equivalent contact dimensions, insulation height, and overall form factor

The N3372-6002RB differs in shrouding design (4-wall versus 3-wall), contact finish on posts (tin versus tin-lead), current rating (1.75A versus 1A), and compliance status (RoHS compliant versus non-compliant).

Engineering Selection Recommendations

The N3372-6002RB is the active equivalent for the obsolete 3372-2002. Selection between these parts depends on regulatory and compliance requirements:

Use N3372-6002RB when:

RoHS compliance is required for new designs or procurement
Current requirements do not exceed 1.75A per contact
Enhanced shrouding (4-wall) provides improved EMI shielding or mechanical protection

Use 3372-2002 when:

Legacy designs require exact part matching with tin-lead post finish
RoHS non-compliant applications are acceptable
Existing inventory must be consumed

Both connectors maintain identical mechanical compatibility, electrical performance within their respective current ratings, and environmental operating specifications. The transition from tin-lead to tin post finish on the N3372-6002RB aligns with modern manufacturing standards and does not affect functional interchangeability in standard solder reflow processes.

Frequently Asked Questions (FAQ)

Q: Are the 3372-2002 and N3372-6002RB mechanically interchangeable?

A: Yes. Both connectors share identical mating pitch (0.100"), row spacing (0.100"), contact dimensions, insulation height (0.680"), and through-hole mounting footprint. The 4-wall shrouding on the N3372-6002RB provides additional mechanical support but does not prevent direct substitution.

Q: What is the impact of the shrouding difference (3-wall versus 4-wall)?

A: The 4-wall shrouding on the N3372-6002RB provides enhanced mechanical retention and improved EMI shielding compared to the 3-wall design of the 3372-2002. This does not affect electrical compatibility but may improve connector robustness in high-vibration or high-EMI environments.

Q: Can the N3372-6002RB replace the 3372-2002 in applications requiring 1A current?

A: Yes. The N3372-6002RB is rated for 1.75A per contact, which exceeds the 1A requirement of the 3372-2002. Current capacity is not a limiting factor for substitution in this direction.

Q: What is the significance of the tin versus tin-lead post finish change?

A: The N3372-6002RB uses tin post finish instead of tin-lead. Both finishes are compatible with standard solder reflow processes. Tin finish aligns with RoHS compliance requirements and modern manufacturing practices without affecting solderability or long-term reliability.

Q: Does the RoHS compliance difference affect functional performance?

A: No. RoHS compliance status reflects manufacturing material composition and regulatory adherence, not electrical or mechanical performance. The N3372-6002RB is functionally equivalent to the 3372-2002 in all electrical and mechanical parameters.

Q: What packaging is available for the N3372-6002RB?

A: The N3372-6002RB is supplied in bulk packaging, as specified in the product data.
