3M 3372-6005 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 3372-6005 is a vertical rectangular connector header designed for through-hole mounting with 60 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This connector features shrouded 4-wall construction, wire wrap termination, and push-pull fastening. The part is classified as obsolete, making identification of active equivalent components essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3M 3372-6005 is determined by strict equivalence across the following critical parameters:

• Connector Configuration: Header type with male pin contacts, 60 positions in 2-row arrangement
• Pitch Specification: 0.100" (2.54mm) mating pitch and 0.100" (2.54mm) row spacing
• Mounting and Termination: Through-hole mounting with wire wrap termination and push-pull fastening
• Shrouding Design: Shrouded 4-wall construction with keying slot and mounting flange
• Electrical Performance: 1A current rating and UL94 V-0 flammability compliance
• Contact Geometry: Mating contact length 0.240" (6.10mm) and post length 0.610" (15.49mm)

The CW Industries CWN-570-60-0021 meets all critical substitution criteria. Variations in contact shape (circular vs. square), contact material (phosphor bronze vs. copper alloy), contact finish composition, insulation material type, and operating temperature upper limit do not preclude functional equivalence within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

The CW Industries CWN-570-60-0021 is the qualified substitute for the obsolete 3M 3372-6005. Selection rationale is based on the following factors:

Product Status: The 3M 3372-6005 is obsolete. The CWN-570-60-0021 maintains active product status, ensuring long-term availability and manufacturing continuity.

Regulatory Compliance: The CWN-570-60-0021 is ROHS3 compliant, whereas the original part is RoHS non-compliant. This compliance status is significant for applications subject to RoHS directives and modern procurement standards.

Electrical and Mechanical Equivalence: Both parts maintain identical specifications across connector configuration, pitch, mounting type, shrouding design, termination method, fastening mechanism, contact geometry, mating contact finish, and current rating. The operating temperature range of the substitute extends to 125°C compared to 105°C for the original, providing enhanced thermal margin.

Functional Compatibility: Differences in contact shape, contact material composition, contact finish post specification, and insulation material type do not affect functional compatibility within the specified electrical and mechanical operating envelope.

Frequently Asked Questions (FAQ)

Q: Can the CW Industries CWN-570-60-0021 be used as a direct replacement for the 3M 3372-6005?

A: Yes. Both connectors share identical pitch (0.100"), position count (60 in 2 rows), mounting type (through-hole), shrouding design (4-wall), termination method (wire wrap), fastening type (push-pull), contact geometry, and current rating (1A). The substitute is functionally equivalent within the specified electrical and mechanical parameters.

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete vs. active), RoHS compliance (non-compliant vs. ROHS3 compliant), operating temperature upper limit (105°C vs. 125°C), contact shape (square vs. circular), contact material (copper alloy vs. phosphor bronze), contact finish post composition (flash vs. 50.0µin nickel), and insulation material type (PBT polyester glass-filled vs. thermoplastic). These differences do not affect functional compatibility.

Q: Are there any compatibility concerns with PCB footprints or mating connectors?

A: No. Both parts maintain identical pitch, row spacing, contact length specifications, and shrouding geometry. Existing PCB footprints and mating connectors designed for the 3M 3372-6005 are compatible with the CWN-570-60-0021.

Q: Does the extended operating temperature range of the substitute provide additional design margin?

A: Yes. The CWN-570-60-0021 operates to 125°C compared to 105°C for the original part, providing 20°C additional thermal margin for applications with elevated ambient or self-heating considerations.

Q: Is the RoHS3 compliance of the substitute significant for my application?

A: RoHS3 compliance is mandatory for products marketed in the European Union and increasingly required by global procurement standards. If your application or supply chain requires RoHS compliance, the CWN-570-60-0021 meets this requirement while the original part does not.
