Key Parameters

Substitute Part Grouping Explanation

The 3M N3372-6002RB qualifies as a direct substitute for the 3372-6205 based on the following critical parameters:

Matching Parameters:

• Connector type, contact type, and gender (Header, Male Pin)
• Position count and row configuration (60 positions, 2 rows)
• Mating pitch and row spacing (0.100" / 2.54mm)
• Shrouding style (Shrouded - 4 Wall)
• Mounting method (Through Hole)
• Contact shape (Square)
• Operating temperature range (-55°C ~ 105°C)
• Flammability rating (UL94 V-0)
• Insulation color (Black)
• Series designation (3000 series)

Allowable Variations:

• Termination method: Wire Wrap (3372-6205) to Solder (N3372-6002RB)
• Fastening type: Latch Lock/Eject Hooks, Short to Push-Pull
• Contact post length and overall contact length
• Contact finish on post: Gold to Tin
• Insulation material: PBT to PCT (both polyester, glass-filled)
• Current rating: 1A to 1.75A
• Product status: Obsolete to Active

These variations are within acceptable substitution parameters for rectangular connector headers in this category.

Parameter Comparison

Engineering Selection Recommendations

The N3372-6002RB is the active equivalent for the obsolete 3372-6205. Selection of the substitute part is supported by:

Product Status: The N3372-6002RB maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete 3372-6205.

Compliance and Certifications: Both parts share identical flammability ratings (UL94 V-0), operating temperature ranges (-55°C ~ 105°C), and moisture sensitivity levels (MSL 1 - Unlimited), confirming equivalent environmental and regulatory performance.

Electrical and Mechanical Compatibility: The substitute maintains identical mating pitch (0.100" / 2.54mm), row spacing, position count (60 positions, 2 rows), shrouding configuration, and contact geometry. These parameters ensure mechanical interchangeability with mating connectors designed for the original part.

Functional Enhancements: The N3372-6002RB provides increased current rating (1.75A versus 1A), offering improved electrical capacity for the same physical form factor.

Termination Consideration: The transition from wire wrap to solder termination requires PCB design modification. Solder termination is standard for modern through-hole connector applications and is compatible with conventional PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the N3372-6002RB directly replace the 3372-6205 without PCB modification?

A: Mechanical and electrical compatibility is confirmed for mating connector interfaces. However, termination method differs: the original uses wire wrap while the substitute uses solder. PCB pad design and assembly process must be adapted accordingly.

Q: Are the contact dimensions identical between these parts?

A: Mating contact length is identical (0.240" / 6.10mm). Post contact length differs: 0.610" (15.49mm) for the 3372-6205 versus 0.112" (2.84mm) for the N3372-6002RB. This difference reflects the termination method change and requires PCB hole depth adjustment.

Q: What is the significance of the insulation material change from PBT to PCT?

A: Both materials are polyester-based, glass-filled polymers meeting UL94 V-0 flammability requirements. PCT (polycyclohexylenedimethylene terephthalate) offers equivalent performance characteristics for this connector application.

Q: Does the higher current rating of the N3372-6002RB affect compatibility?

A: The increased current rating (1.75A versus 1A) represents improved electrical capacity. This change does not affect mechanical or mating compatibility and provides additional design margin for applications requiring higher current handling.

Q: What is the difference between the fastening types listed?

A: The 3372-6205 uses Latch Lock/Eject Hooks with short engagement, while the N3372-6002RB uses Push-Pull fastening. Both provide secure mating and unmating mechanisms suitable for board-to-board or cable applications.

Q: Are both parts available in the same packaging options?

A: The 3372-6205 packaging is not specified in available data. The N3372-6002RB is supplied in Bulk packaging, which is standard for active production components.

Q: Do both parts meet the same export control classifications?

A: Yes, both parts are classified under ECCN EAR99 and HTSUS 8536.69.4040, confirming equivalent export control status.
