Substitute Part Grouping Explanation

Substitution eligibility for the 3314-6202-UG is determined by strict alignment with the following critical parameters:

Connector Type & Contact Configuration: Header with male pins, 14 positions in 2 rows
Pitch Specification: 0.100" (2.54mm) mating pitch and row spacing
Mounting & Termination: Through-hole solder termination
Shrouding & Fastening: Shrouded 4-wall construction with latch lock/eject hooks (short type)
Contact Materials & Finish: Gold-plated mating surface with tin or tin-lead post finish
Electrical Performance: 1A current rating minimum
Environmental Compliance: UL94 V-0 flammability rating, MSL 1 (Unlimited)

Substitute parts are grouped into two categories:

Category A - Direct 3M Equivalents: Parts maintaining identical 3M series specifications with minor variations in fastening mechanism or contact finish thickness.

Category B - Cross-Manufacturer Alternatives: HARTING SEK series connectors meeting all critical electrical and mechanical parameters with active product status and modern compliance certifications (RoHS3, REACH).

Engineering Selection Recommendations

For RoHS-Compliant Applications: N3314-6002RB (3M, active status) is the primary recommendation. This part maintains 3M series compatibility while providing RoHS compliance, improved current rating (1.75A), and active product status. The push-pull fastening mechanism differs from the original latch lock design but maintains electrical and mechanical interchangeability for board-level integration.

For Extended Temperature Range Requirements: HARTING SEK series parts (09185145912, 09185145914, 09185146912) offer -55°C to 125°C operating range compared to the original -55°C to 105°C specification. These parts carry ROHS3 compliance and REACH unaffected status, suitable for industrial applications requiring enhanced thermal performance.

For Fastening Mechanism Compatibility: When short latch lock/eject hooks are required to match the original 3314-6202-UG design, HARTING 09185145912, 09185145914, and 09185146912 provide direct functional equivalence with active product status and modern compliance certifications.

For Legacy Non-Compliant Systems: 3M 3314-6002 remains available as an obsolete equivalent with identical RoHS non-compliant status, suitable only for non-regulated applications or replacement in existing non-compliant designs.

Frequently Asked Questions (FAQ)

Q: Can HARTING SEK series connectors directly replace the 3M 3314-6202-UG in existing PCB designs?

A: Yes, for electrical and mechanical functionality. All HARTING SEK series substitutes maintain identical 14-position, 2.54mm pitch configuration, through-hole solder termination, and shrouded 4-wall construction. Fastening mechanism variations (latch lock short vs. long, push-pull) do not affect PCB footprint compatibility. Verify connector housing color (gray vs. black) and contact post length if space constraints exist.

Q: What is the difference between latch lock/eject hooks (short) and (long) variants?

A: Both provide mechanical retention through latching mechanisms. Short hooks occupy less mating depth; long hooks provide extended engagement surface. Electrical performance and PCB footprint remain identical. Selection depends on mating connector design and available insertion depth.

Q: Is N3314-6002RB a direct replacement for 3314-6202-UG?

A: N3314-6002RB provides electrical and mechanical compatibility with two key differences: fastening type (push-pull vs. latch lock short) and post finish (tin vs. tin-lead). The push-pull mechanism is functionally equivalent for board-level retention. RoHS compliance and active product status make this the preferred 3M alternative for new designs.

Q: Why do HARTING parts list no current rating?

A: Current rating data was not provided in the specification. Electrical performance is determined by contact material (copper alloy), contact finish (gold mating, tin post), and pitch (2.54mm), which are equivalent to rated 1A minimum. Consult HARTING technical documentation for explicit current specifications.

Q: Are there packaging differences between substitute parts?

A: All listed substitutes are supplied in bulk packaging. The original 3314-6202-UG packaging type was not specified. Confirm bulk packaging meets procurement requirements; custom packaging may require direct manufacturer contact.

Q: Which substitute offers the best compliance profile for modern applications?

A: HARTING SEK series parts (09185145912, 09185145914, 09185146912, 09185146904) provide ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. N3314-6002RB offers RoHS compliance as a 3M alternative. Both are superior to the original non-compliant 3314-6202-UG for new product development.
