3M 3372-2003 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 3372-2003 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 3-wall construction with male pin contacts, gold-plated mating surfaces, and tin-lead post finishes. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 3372-2003 is determined by the following critical parameters:

• 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)
• Termination type (Solder)
• Contact finish on mating surface (Gold)
• Operating temperature range (-55°C ~ 105°C minimum)
• Flammability rating (UL94 V-0)

The identified substitute parts maintain these core electrical and mechanical parameters. Variations in shrouding configuration (3-wall vs. 4-wall), contact post finish composition, contact material type, and current rating capacity do not preclude functional substitution when the mating interface and board-level integration requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

The 3M 3372-2003 is classified as obsolete. Both identified substitute parts maintain functional compatibility through identical mating pitch, position count, row configuration, and contact interface specifications.

The 3M N3372-6002RB substitute offers the advantage of active product status with RoHS compliance certification. The 4-wall shrouding provides enhanced mechanical protection compared to the original 3-wall design. The increased current rating of 1.75A exceeds the original 1A specification. This part represents a direct manufacturer upgrade path within the 3M 3000 series.

The CW Industries CWN-360-60-0021 substitute provides active product status with ROHS3 compliance. The extended operating temperature range to 125°C offers additional thermal margin. The 4-wall shrouding matches the 3M substitute. Contact material composition differs (phosphor bronze vs. copper alloy) and contact post finish is nickel rather than tin-lead. This part accommodates board-to-cable/wire applications.

Both substitutes satisfy the core electrical and mechanical requirements for applications previously served by the 3372-2003. Selection between substitutes depends on specific application requirements regarding shrouding style, contact material preferences, and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the 3M N3372-6002RB directly replace the 3372-2003 in existing designs?

A: Yes. Both parts share identical mating pitch (0.100" / 2.54mm), position count (60), row configuration (2 rows), contact type (male pin), and gold-plated mating surface finish. The 4-wall shrouding of the N3372-6002RB provides equivalent or enhanced mechanical protection. The increased current rating (1.75A vs. 1A) is compatible with applications designed for the original 1A specification.

Q: What are the key differences between the 3M N3372-6002RB and CW Industries CWN-360-60-0021 substitutes?

A: Both maintain identical mating interface specifications. The 3M N3372-6002RB uses copper alloy contacts with tin post finish and operates to 105°C. The CW Industries CWN-360-60-0021 uses phosphor bronze contacts with nickel post finish and operates to 125°C. The CW Industries part is specified for board-to-cable/wire applications, while the 3M part supports board-to-board or cable configurations. Contact material and post finish differences may affect performance in specific corrosive or high-frequency environments.

Q: Are there packaging or inventory considerations for these substitutes?

A: The 3M 3372-2003 is obsolete with limited remaining inventory (980 pcs). The 3M N3372-6002RB is active with 1088 pcs available in bulk packaging. The CW Industries CWN-360-60-0021 is active with 951 pcs available in bulk packaging. Both substitutes offer reliable procurement availability.

Q: Do the substitute parts meet current compliance requirements?

A: The 3M 3372-2003 is RoHS non-compliant. The 3M N3372-6002RB is RoHS compliant. The CW Industries CWN-360-60-0021 is ROHS3 compliant. Both substitutes satisfy current regulatory compliance standards. The CW Industries part includes REACH unaffected status confirmation.

Q: What determines whether a part can substitute for the 3372-2003?

A: Substitution requires matching 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), termination type (solder), mating contact finish (gold), operating temperature range (-55°C minimum to 105°C minimum), and flammability rating (UL94 V-0). Variations in shrouding configuration, post finish material, and contact material do not preclude substitution when these core parameters are satisfied.
