Engineering Selection Recommendations

N3372-5002RB is the qualified substitute for the obsolete 3372-5305. Both parts share identical mating interface specifications, electrical ratings, and environmental performance characteristics. The substitute part carries active product status with RoHS compliance and REACH unaffected designation, providing regulatory continuity for new designs and system updates.

Selection of N3372-5002RB requires evaluation of termination method compatibility. The original 3372-5305 uses wire wrap termination with long latch lock/eject fastening, while N3372-5002RB employs solder termination with push-pull fastening. These differences necessitate assessment of PCB layout, assembly process, and mechanical mounting requirements specific to the application.

Frequently Asked Questions (FAQ)

Q: Can N3372-5002RB directly replace 3372-5305 in existing assemblies?

A: Electrical and mechanical mating interfaces are identical. Physical mounting and termination methods differ. Direct replacement requires verification that PCB footprint, assembly process, and mechanical retention scheme accommodate solder termination and push-pull fastening instead of wire wrap and latch lock configuration.

Q: What are the key differences between these parts?

A: The primary differences are termination method (wire wrap vs. solder), fastening mechanism (latch lock/eject vs. push-pull), contact post length (0.610" vs. 0.112"), and post finish material (gold vs. tin). Mating interface specifications, pitch, position count, and electrical ratings remain identical.

Q: Is N3372-5002RB suitable for new designs?

A: Yes. N3372-5002RB is an active product with RoHS compliance and REACH unaffected status, making it appropriate for new design implementations. The solder termination and push-pull fastening are standard for modern PCB assembly processes.

Q: What is the significance of the different insulation materials?

A: Both materials (PBT and PCT) are polyester-based, glass-filled compounds with identical flammability ratings (UL94 V-0) and operating temperature ranges (-55°C ~ 105°C). Material selection reflects manufacturing process differences and does not affect functional performance or compatibility.

Q: Are there packaging differences between these parts?

A: 3372-5305 packaging is not specified in available documentation. N3372-5002RB is supplied in bulk packaging. Confirm packaging requirements for procurement and inventory management.
