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

Part Overview

The 3M 2510-6002UG is a shrouded rectangular connector header designed for through-hole mounting with 10 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This connector features male pins with gold-plated mating contacts and tin-lead plated posts, suitable for board-to-board or cable applications. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for new designs and production continuity.

Engineering Selection Recommendations

Primary Recommendation: N2510-6002-RB (3M)

The N2510-6002-RB is the direct active replacement within the 3M 2500 series family. It maintains identical electrical and mechanical specifications to the 2510-6002UG while achieving ROHS3 compliance. This part is preferred for designs requiring continuity with the original 3M platform and offers the highest inventory availability (65,098 units in stock).

Secondary Recommendation: D2510-6002-AR (3M D2500 Series)

The D2510-6002-AR represents the manufacturer-recommended upgrade path from the obsolete 2510 series to the active D2500 series. It provides full electrical compatibility with identical pitch, position count, and contact configuration. This part achieves RoHS compliance and is suitable for new designs requiring regulatory adherence.

Cross-Manufacturer Alternatives:

Molex C-Grid series (0702461001, 0702461004) and C-Grid 87834 series (0878341011, 0878341019, 0878341041) provide functionally equivalent substitutes with ROHS3 compliance and active product status. These alternatives are suitable when supply chain diversification or specific packaging requirements (bulk, bag, tray) are necessary.

HARTING SEK series (09195105324) and TE Connectivity AMP-Latch series (103308-1) are compatible alternatives with extended operating temperature ranges and active status. The HARTING part supports operation to 125°C, and the TE Connectivity part maintains tin-lead post finish matching the original specification.

Compliance Considerations:

For applications requiring RoHS compliance, N2510-6002-RB, D2510-6002-AR, and all Molex and HARTING alternatives meet ROHS3 standards. The TE Connectivity 103308-1 maintains RoHS non-compliance status matching the original part.

Frequently Asked Questions (FAQ)

Q: Can the N2510-6002-RB directly replace the 2510-6002UG without PCB redesign?

A: Yes. The N2510-6002-RB maintains identical pitch (0.100"), position count (10), row configuration (2 rows), and mounting type (through hole). Pin-to-pin compatibility is preserved. The only difference is post finish (tin versus tin-lead), which does not affect mechanical fit or electrical performance in solder termination applications.

Q: What is the difference between tin and tin-lead post finishes?

A: Both finishes are suitable for solder termination. Tin-lead (the original 2510-6002UG specification) contains 63% tin and 37% lead. Tin finish (used in N2510-6002-RB and most active alternatives) is lead-free and meets RoHS requirements. Both provide equivalent solderability and contact resistance in this connector application.

Q: Are Molex C-Grid connectors mechanically compatible with 3M 2510 series receptacles?

A: Molex C-Grid series (0702461001, 0702461004) and 3M 2510/N2510 series share identical mating pitch (0.100"), position count (10), row spacing (0.100"), and shrouding configuration (4-wall). Mechanical mating compatibility is confirmed. Electrical performance is equivalent across all specified parameters.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in multiple packaging formats: tray (N2510-6002-RB, D2510-6002-AR, 0702461004, 0878341011, 0878341019, 0878341041), bulk (0702461001, 09195105324, 103308-1), and bag (0702461003). Selection depends on production volume and handling requirements.

Q: Does the Molex 0702461003 (9 positions loaded) substitute for the 10-position 2510-6002UG?

A: No. The 0702461003 is loaded with 9 positions, while the 2510-6002UG requires all 10 positions loaded. This part does not provide functional equivalence for applications requiring the full 10-position configuration.

Q: Which substitute part offers the widest operating temperature range?

A: The HARTING 09195105324 supports -55°C to 125°C, extending the upper temperature limit by 20°C compared to the original 2510-6002UG specification (-55°C to 105°C). This part is suitable for applications requiring enhanced thermal performance.

Q: Are all substitute parts UL94 V-0 rated?

A: Yes. All listed substitute parts meet UL94 V-0 material flammability rating, matching the original 2510-6002UG specification.
