Engineering Selection Recommendations

Primary Recommendation for Active Product Status: The 3M N3372-6002RB offers the most direct functional upgrade from the obsolete 3372-6302. Both are 3M products with identical mating pitch and row spacing. The N3372-6002RB achieves active product status and RoHS compliance while maintaining the same contact post length (0.112"). The fastening type transitions from latch lock/eject hooks to push-pull, and current rating increases to 1.75A, providing enhanced performance margins.

Alternative Recommendations for RoHS Compliance: TE Connectivity AMP-Latch series parts (1-5102321-1, 1-5111490-1, 1-5499206-1, 1-5499922-1, 1-5499923-1, 3-5102321-1, 3-5499206-1) provide active product status with RoHS or ROHS3 compliance. These parts maintain the latch lock/eject hook fastening type matching the original 3372-6302 design. Contact post length variations (0.110" or 0.155") accommodate different PCB thicknesses and mating depths. Selection between these variants depends on specific board assembly requirements and packaging preferences (bulk or tray).

Compliance Considerations: Parts with RoHS Compliant or ROHS3 Compliant status are preferred for new designs and production continuity. The original 3372-6302 is RoHS non-compliant; substitution with compliant alternatives addresses regulatory requirements for electronics manufacturing and end-of-life recycling.

Frequently Asked Questions (FAQ)

Q: Can I directly replace 3372-6302 with N3372-6002RB? A: Yes. Both parts maintain 60 positions, 2 rows, 0.100" (2.54mm) pitch, shrouded 4-wall construction, and solder termination. The fastening mechanism changes from latch lock/eject hooks to push-pull, and current rating increases from 1A to 1.75A. Mechanical fit and electrical performance are compatible for board-to-cable/wire applications.

Q: What is the difference between contact post lengths (0.110", 0.112", 0.155")? A: Contact post length determines mating depth and engagement with receptacle contacts. The original 3372-6302 specifies 0.112" (2.84mm). Substitute parts offer 0.110" (2.79mm) or 0.155" (3.94mm) variants. Selection depends on PCB thickness, solder pad depth, and mating connector specifications. Consult mating connector documentation to confirm compatibility.

Q: Are TE Connectivity AMP-Latch parts electrically equivalent to 3M 3372-6302? A: Yes. TE Connectivity 1-5102321-1, 1-5111490-1, 1-5499206-1, 1-5499922-1, 1-5499923-1, 3-5102321-1, and 3-5499206-1 maintain the same 60-position, 2-row configuration with 0.100" (2.54mm) pitch, shrouded 4-wall design, and solder termination. All operate within -65°C ~ 105°C temperature range and meet UL94 V-0 flammability requirements. Current ratings are 1A or 1A per contact, matching or exceeding the original specification.

Q: What packaging options are available? A: Substitute parts are supplied in bulk or tray packaging. N3372-6002RB is available in bulk. TE Connectivity parts are available in bulk (1-5111490-1, 1-5499922-1, 1-5499923-1) or tray (1-5102321-1, 1-5499206-1, 3-5102321-1, 3-5499206-1). Packaging selection affects handling, storage, and automated assembly processes. Confirm packaging requirements with procurement and assembly specifications.

Q: Does insulation color affect compatibility? A: The original 3372-6302 specifies black insulation. Most substitute parts maintain black insulation. Parts 3-5102321-1 and 3-5499206-1 feature blue insulation. Insulation color does not affect electrical or mechanical function. Selection depends on design documentation and assembly traceability requirements.

Q: Which substitute part offers the best RoHS compliance status? A: Parts with ROHS3 Compliant status (1-5499206-1, 1-5499922-1) represent the most current compliance certification. Parts with RoHS Compliant status (N3372-6002RB, 1-5102321-1, 1-5499923-1, 3-5102321-1, 3-5499206-1) meet established RoHS requirements. Both certifications satisfy regulatory requirements for electronics manufacturing. ROHS3 compliance indicates alignment with the most recent directive updates.
