3372-L302 Equivalent & Substitute Parts

Part Overview

The 3372-L302 is a rectangular connector header manufactured by 3M, designed for through-hole, right-angle board-to-board or cable applications. This 60-position, 2-row connector operates across -55°C to 105°C and features shrouded 4-wall construction with gold-plated mating contacts and tin-lead plated posts. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The 87061-330 manufactured by Amphenol ICC (FCI) qualifies as a functional substitute for the 3372-L302 based on the following critical parameters:

Matching Parameters:

• Connector Type: Header, Stackable (2)
• Contact Type: Male Pin
• Number of Positions: 60
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole, Right Angle
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Contact Finish - Mating: Gold
• Contact Finish Thickness - Mating: 30.0µin (0.76µm)
• Material Flammability Rating: UL94 V-0
• RoHS Status: RoHS non-compliant
• Moisture Sensitivity Level: 1 (Unlimited)

These parameters define the core mechanical and electrical compatibility required for direct substitution in board-to-board or cable connection applications.

Parameter Comparison

Engineering Selection Recommendations

The 87061-330 is the designated substitute for the obsolete 3372-L302. Both connectors maintain identical mating pitch, position count, row configuration, and shrouding specifications. The 87061-330 carries active product status, ensuring ongoing availability and supply chain continuity.

Both parts comply with UL94 V-0 flammability requirements and carry identical RoHS non-compliant and MSL 1 classifications. The 87061-330 employs GXT™ gold plating on mating contacts, which meets the 30.0µin thickness specification of the original part.

Physical dimensions differ slightly: the 87061-330 insulation height is 0.710" (18.03mm) compared to the 3372-L302 at 0.660" (16.76mm), and post contact length is 0.105" (2.67mm) versus 0.112" (2.84mm). These variations remain within acceptable tolerances for standard board-to-board applications where connector height and post engagement are not critical design constraints.

Frequently Asked Questions (FAQ)

Q: Can the 87061-330 directly replace the 3372-L302 in existing designs?

A: Yes. Both connectors share identical mating pitch (0.100"), position count (60), row configuration (2), and shrouding type (4-wall). The mechanical interface and electrical contact specifications are equivalent.

Q: What are the physical dimension differences between these parts?

A: The 87061-330 has an insulation height of 0.710" (18.03mm) versus 0.660" (16.76mm) for the 3372-L302. Post contact length differs by 0.007" (0.17mm). These differences are minor and do not affect standard board-to-board mating applications.

Q: Are there differences in contact material composition?

A: Yes. The 3372-L302 uses copper alloy contacts with tin-lead plating on posts. The 87061-330 uses phosphor bronze contacts. Both maintain gold plating on mating surfaces at 30.0µin thickness, ensuring equivalent electrical performance.

Q: What is the significance of the GXT™ gold plating on the 87061-330?

A: GXT™ is Amphenol's proprietary gold plating specification. It meets the 30.0µin thickness requirement of the original part and provides equivalent contact reliability and conductivity.

Q: Are both parts RoHS compliant?

A: No. Both the 3372-L302 and 87061-330 are RoHS non-compliant. If RoHS compliance is required, alternative connector families must be evaluated.

Q: What is the current rating for the 87061-330?

A: The current rating for the 87061-330 is not specified in the available data. The 3372-L302 is rated at 1.75A per contact. Verify current requirements with Amphenol ICC technical documentation if current capacity is a design constraint.

Q: Are both connectors suitable for the same temperature range?

A: The 3372-L302 operates from -55°C to 105°C. The operating temperature range for the 87061-330 is not specified in the available data. Confirm temperature requirements with the manufacturer if operation outside standard industrial ranges is required.
