Engineering Selection Recommendations

The N3372-6002RB is the designated substitute for the obsolete 3372-2302. Selection of the active substitute is supported by:

Product Status: The original part is obsolete, while the substitute maintains active production status, ensuring long-term availability and supply chain continuity.

Compliance: The substitute achieves RoHS compliance, addressing regulatory requirements for new designs and procurement cycles. The original part's RoHS non-compliant status limits its use in regulated applications.

Electrical Compatibility: Both parts maintain identical mating pitch (0.100"), position count (60), contact geometry, and temperature rating (-55°C ~ 105°C), ensuring direct electrical compatibility in existing circuit designs.

Mechanical Compatibility: Identical contact lengths, insulation height, and solder termination specifications confirm mechanical interchangeability in PCB layouts and connector receptacles designed for the original part.

Performance Enhancement: The substitute's increased current rating (1.75A vs. 1A) and 4-wall shrouding provide improved electrical performance and mechanical robustness without compromising compatibility.

Frequently Asked Questions (FAQ)

Q: Can the N3372-6002RB directly replace the 3372-2302 in existing designs?

A: Yes. The substitute maintains identical mating pitch (0.100"), position count (60), contact geometry, and temperature rating. PCB layouts and mating connectors designed for the original part are mechanically and electrically compatible with the substitute.

Q: What are the key differences between these parts?

A: The substitute features 4-wall shrouding versus 3-wall, push-pull fastening versus latch lock hooks, and increased current rating (1.75A vs. 1A). The substitute also achieves RoHS compliance and maintains active production status.

Q: Does the change from tin-lead to tin post finish affect compatibility?

A: No. Both finishes provide equivalent solder joint reliability and electrical performance. The tin post finish in the substitute aligns with modern lead-free soldering practices.

Q: Is the increased current rating of the substitute a concern for existing applications?

A: No. The higher current rating (1.75A) represents improved capability and does not negatively impact applications designed for the original 1A rating.

Q: What is the significance of the 4-wall versus 3-wall shrouding difference?

A: The 4-wall shrouding in the substitute provides enhanced mechanical protection and improved contact alignment. This represents a functional improvement suitable for direct substitution.

Q: Are there packaging differences between these parts?

A: The original part packaging is not specified. The substitute is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: Does RoHS compliance of the substitute affect compatibility?

A: No. RoHS compliance indicates the substitute meets environmental and regulatory standards. This is an advantage for new designs and regulated applications.
