3M 2510-6002UB Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 2510-6002UB is a shrouded rectangular connector header with 10 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This through-hole component features male pins with gold-plated mating contacts and tin-lead post finishes, designed for board-to-board or cable connections. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Active alternatives from 3M and other manufacturers provide compatible electrical and mechanical interfaces while offering improved compliance status and availability.

Substitute parts are grouped into two categories:

Category 1: Direct 3M Series Substitutes - Parts N2510-6002-RB and D2510-6002-AR maintain the same electrical interface and mechanical footprint as the original 2510-6002UB. These parts differ in contact material composition, post finish specifications, and compliance status but preserve full functional compatibility.

Category 2: Cross-Manufacturer Alternatives - Molex C-Grid 70246 series (0702461001, 0702461003, 0702461004), Molex C-Grid 87834 series (0878341011, 0878341019, 0878341041), HARTING SEK series (09195105324), and TE Connectivity AMP-Latch series (103308-1) provide equivalent electrical and mechanical performance. These parts share identical mating pitch, position count, shrouding configuration, and through-hole mounting but may exhibit minor variations in contact length, insulation height, and material composition within acceptable tolerance ranges.

Engineering Selection Recommendations

For RoHS3 Compliant Applications: Select N2510-6002-RB, D2510-6002-AR, or any Molex or HARTING substitute. These parts meet current regulatory requirements while maintaining full electrical and mechanical compatibility with the original 2510-6002UB interface.

For Legacy Non-Compliant Systems: 103308-1 from TE Connectivity AMP-Latch series provides functional equivalence with RoHS non-compliant status matching the original part, though this option is not recommended for new designs.

For Extended Temperature Range: 09195105324 from HARTING SEK series supports -55°C to 125°C operating range, exceeding the original specification of -55°C to 105°C.

For Immediate Availability: Molex C-Grid 70246 series (0702461001, 0702461004) and Molex C-Grid 87834 series (0878341011, 0878341019, 0878341041) offer the highest inventory levels across multiple packaging options (Bulk, Tray, Bag).

For Direct 3M Ecosystem: N2510-6002-RB provides the closest functional match within the 3M 2500 series family, with active product status and ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can N2510-6002-RB directly replace 2510-6002UB in existing designs?

A: Yes. N2510-6002-RB maintains identical mating pitch (0.100"), position count (10), row spacing (0.100"), shrouding configuration (4-wall), and through-hole mounting. The primary difference is post finish material (Tin vs. Tin-Lead) and RoHS3 compliance status. Electrical and mechanical interfaces are fully compatible.

Q: What is the difference between Molex 0702461001 and 0702461004?

A: Both parts are from the C-Grid 70246 series with identical electrical and mechanical specifications. The primary difference is packaging: 0702461001 is supplied in Bulk packaging, while 0702461004 is supplied in Tray packaging. Contact finish thickness on mating surfaces also differs (15.0µin vs. 5.00µin), but both meet functional requirements.

Q: Why does 0702461003 show 9 positions loaded instead of 10?

A: 0702461003 is a variant with 9 positions loaded rather than all 10. This part is not a direct substitute for 2510-6002UB, which requires all 10 positions loaded. Use 0702461001 or 0702461004 for full 10-position equivalence.

Q: Are Molex C-Grid 87834 series parts (0878341011, 0878341019, 0878341041) interchangeable with each other?

A: All three parts share identical electrical and mechanical specifications. Differences are limited to insulation material composition and color: 0878341011 uses Polyamide (PA46) with Beige insulation, 0878341019 uses Polybutylene Terephthalate (PBT) with Black insulation, and 0878341041 uses Polyamide (PA) with Natural insulation. Selection depends on material compatibility requirements for the application.

Q: Does HARTING 09195105324 have different fastening compared to the original?

A: Yes. The original 2510-6002UB uses Push-Pull fastening, while 09195105324 uses Latch Holder fastening. This difference does not affect mating compatibility but may impact connector handling and retention characteristics in the application.

Q: What compliance certifications apply to these substitutes?

A: All substitute parts carry UL94 V-0 material flammability rating. Most are ROHS3 Compliant and REACH Unaffected. The original 2510-6002UB and TE Connectivity 103308-1 are RoHS non-compliant and REACH Affected. Verify compliance requirements for your specific application before selection.

Q: Can I mix substitute parts from different manufacturers in the same assembly?

A: All listed substitutes maintain identical mating pitch, position count, and shrouding, allowing mechanical interchangeability. However, verify contact material compatibility and post finish specifications with your connector supplier before mixing manufacturers in critical applications.
