3372-6602UG Equivalent & Substitute Parts

Part Overview

The 3372-6602UG is a rectangular connector header manufactured by 3M, designed for through-hole mounting applications requiring 60-position, 2-row board-to-board or cable connections at 0.100" (2.54mm) pitch. This connector features shrouded 4-wall construction with latch lock/eject hooks and gold-plated mating contacts. The product is currently obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3372-6602UG is determined by strict alignment across 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)
• Shrouding configuration (Shrouded - 4 Wall)
• Mounting method (Through Hole)
• Termination type (Solder)
• Operating temperature range (-55°C ~ 105°C minimum)
• Contact finish on mating surface (Gold)
• Flammability rating (UL94 V-0)

All three substitute parts meet these core criteria. Variations in secondary parameters such as fastening mechanism, contact material composition, insulation material type, and current rating do not preclude substitution when the primary electrical and mechanical interfaces remain compatible.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products with current manufacturing support, addressing the obsolescence status of the 3372-6602UG.

N3372-6002RB is a direct 3M product line continuation within the 3000 series. It maintains identical core electrical and mechanical specifications while offering improved RoHS compliance and higher current rating (1.75A). The primary design difference is the fastening mechanism change from latch lock/eject hooks to push-pull, which affects mating/unmating force characteristics but not electrical compatibility.

1-5111490-1 from TE Connectivity AMP Connectors provides the widest operating temperature range (-65°C ~ 105°C) and includes voltage rating specification (250VAC). It retains the original latch lock/eject hook fastening mechanism and maintains 1A per contact current rating. The contact material composition (Phosphor Bronze) and insulation material (Polyamide/Nylon) differ from the original but remain within acceptable substitution parameters.

AWH 60G-0232-T from Assmann WSW Components offers the highest current rating (3A) and operates within a narrower temperature range (-40°C ~ 105°C). It maintains the latch lock/eject hook fastening mechanism and provides ROHS3 compliance. The insulation color is gray rather than black.

Selection should prioritize product status (all active), RoHS compliance requirements for the application, operating temperature envelope, and fastening mechanism compatibility with existing mating connectors.

Frequently Asked Questions (FAQ)

Q: Can N3372-6002RB replace 3372-6602UG in existing designs?

A: Yes. Both connectors share identical pitch (0.100" / 2.54mm), position count (60), row configuration (2), shrouding (4-wall), mounting type (through-hole), and termination (solder). The fastening mechanism differs (push-pull vs. latch lock/eject hooks), which affects mating force but not electrical interface compatibility. Mechanical compatibility with the mating connector must be confirmed.

Q: What is the significance of the RoHS compliance difference?

A: The 3372-6602UG is RoHS non-compliant, while all three substitutes are RoHS compliant. For applications subject to RoHS regulations or customer requirements, the substitute parts provide regulatory alignment. For legacy systems without RoHS mandates, this difference is not a functional constraint.

Q: Does the current rating difference affect substitution?

A: The 3372-6602UG is rated at 1A. N3372-6002RB (1.75A) and AWH 60G-0232-T (3A) have higher ratings and are fully compatible. 1-5111490-1 matches the original 1A rating. Higher current ratings provide design margin and do not create incompatibility.

Q: Are there temperature range limitations?

A: The 3372-6602UG operates from -55°C to 105°C. N3372-6002RB matches this range exactly. 1-5111490-1 extends to -65°C (wider range, fully compatible). AWH 60G-0232-T operates from -40°C to 105°C (narrower range; verify application requirements). All three meet or exceed the original specification.

Q: What packaging options are available?

A: N3372-6002RB is supplied in bulk packaging. 1-5111490-1 is supplied in bulk packaging. AWH 60G-0232-T is supplied in tray packaging. Packaging selection depends on procurement volume and handling requirements.

Q: How do contact material differences affect performance?

A: The 3372-6602UG uses copper alloy contacts. N3372-6002RB also uses copper alloy. 1-5111490-1 uses phosphor bronze, and AWH 60G-0232-T uses brass. All three materials are standard for connector applications and provide equivalent electrical performance within the specified current and voltage parameters.

Q: Is the insulation material change from PBT to PCT significant?

A: N3372-6002RB substitutes PCT (Polycyclohexylenedimethylene Terephthalate) for the original PBT (Polybutylene Terephthalate). Both are polyester-based thermoplastics with glass reinforcement and UL94 V-0 flammability ratings. This change does not affect electrical or mechanical compatibility for standard applications.
