Connector Type & Contact Configuration: Header with male pins, 14 positions, 2 rows
Pitch Specifications: Mating pitch 0.100" (2.54mm), row spacing 0.100" (2.54mm)
Physical Form Factor: Shrouded 4-wall design, through-hole mounting, solder termination
Fastening & Interface: Push-pull fastening type for board-to-board or board-to-cable applications
Environmental Compliance: UL94 V-0 flammability rating, MSL 1 rating
Contact Performance: Gold-plated mating surface, current rating minimum 1.75A

Substitute parts must maintain compatibility across these core parameters. Variations in contact material, post finish composition, insulation height, and contact length are permissible within the mechanical envelope constraints of the connector family.

Engineering Selection Recommendations

Primary Recommendation: N2514-6002-RB (3M)

The N2514-6002-RB is the direct active equivalent from 3M. It maintains identical electrical and mechanical specifications to the 2514-6002UG, including contact length, insulation height, and operating temperature range. The part is ROHS3 compliant and REACH unaffected, addressing regulatory requirements of the obsolete predecessor. Inventory availability is substantial at 38,199 units.

Secondary Recommendation: D2514-6002-AR (3M)

The D2514-6002-AR is an active 3M alternative from the D2500 series. It maintains core connector specifications but features reduced insulation height (0.253" vs. 0.390"), which may require PCB layout verification. This part is RoHS compliant and REACH unaffected. Inventory is available at 7,791 units. The lower profile may be advantageous in space-constrained applications.

Cross-Manufacturer Alternatives: Amphenol ICC (FCI) Quickie™ Series

The Amphenol ICC (FCI) Quickie™ series provides functional equivalents with the following considerations:

52601-S14-4LF: Maintains 0.365" insulation height and 0.120" post length. RoHS compliant, REACH unaffected. 1,903 units in stock.
52601-G14-4LF: Similar specifications with 30.0µin mating contact finish. RoHS compliant, REACH affected. 2,700 units in stock.
66506-037LF and 66506-068LF: Board-to-cable variants with 0.105" post length. RoHS compliant. 1,414 and 977 units respectively.

Alternative Consideration: KYOCERA AVX 008383014000010

The KYOCERA AVX part 008383014000010 provides functional equivalence with nylon insulation material and nickel post finish. Current rating is specified at 1A, which is lower than the main part's 1.75A rating. This part is ROHS3 compliant and REACH unaffected. Inventory is limited at 861 units.

Compliance Considerations

The original 2514-6002UG is RoHS non-compliant with tin-lead post finish. All recommended substitutes are RoHS compliant or ROHS3 compliant, with lead-free or tin-only post finishes. REACH status varies across alternatives; N2514-6002-RB and D2514-6002-AR are REACH unaffected, making them preferred for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the 2514-6002UG with N2514-6002-RB without PCB modifications?

A: Yes. The N2514-6002-RB maintains identical contact length, insulation height, and pitch specifications. No PCB layout changes are required for direct substitution.

Q: What is the difference between the 3M D2514-6002-AR and N2514-6002-RB?

A: The primary difference is insulation height. The D2514-6002-AR has 0.253" height versus 0.390" for the N2514-6002-RB. Both maintain the same pitch and contact specifications. The D2514-6002-AR is suitable for applications with height constraints.

Q: Are the Amphenol ICC (FCI) Quickie™ parts fully compatible with the 2514-6002UG?

A: Amphenol ICC (FCI) parts maintain the same pitch, position count, and shrouding configuration. Contact length variations exist: Quickie™ series mating contact length is 0.230" versus 0.243" for the 3M part. This difference is within typical connector tolerance ranges but should be verified for specific mating interface requirements.

Q: What is the significance of the contact finish thickness differences?

A: Contact finish thickness affects durability and wear resistance. The 2514-6002UG specifies 15.0µin mating finish. Substitutes range from 10.0µin to 30.0µin. Higher thickness provides greater durability for high-cycle mating applications. Lower thickness is acceptable for static or low-cycle applications.

Q: Why do some substitutes show "Not Specified" for operating temperature?

A: Operating temperature specifications are provided by manufacturers based on material and design validation. Amphenol ICC (FCI) Quickie™ series parts do not specify operating temperature in the provided data. Consult manufacturer datasheets for thermal performance details if operating temperature range is critical to your application.

Q: Is the KYOCERA AVX 008383014000010 suitable as a substitute?

A: The KYOCERA AVX part provides functional equivalence with identical pitch and position count. However, the specified current rating is 1A, which is lower than the 2514-6002UG's 1.75A rating. Use this part only if your application current requirements do not exceed 1A.

Q: What does RoHS compliance mean for connector selection?

A: RoHS compliance indicates the part contains no lead, mercury, cadmium, or other restricted substances. All recommended substitutes are RoHS compliant or ROHS3 compliant, meeting current regulatory requirements for electronics manufacturing and end-of-life recycling.

Q: Are there packaging differences between these substitutes?

A: The 2514-6002UG packaging is not specified in the provided data. All substitute parts are supplied in trays. Confirm packaging requirements with your procurement process, as tray packaging may differ from the original packaging format.

Q: Can I use 66506-068LF instead of 66506-068?

A: Both parts are functionally identical with the same specifications. The primary difference is RoHS compliance: 66506-068LF is RoHS compliant while 66506-068 is RoHS non-compliant. For new designs, use 66506-068LF.
