3M 2516-6002-UB Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 2516-6002-UB is a shrouded rectangular connector header with 16 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 Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters: 16-position configuration, 2-row arrangement, 0.100" (2.54mm) mating pitch, 0.100" (2.54mm) row spacing, shrouded 4-wall design, through-hole mounting, solder termination, push-pull fastening, and male pin contact type. All substitute parts maintain these electrical and mechanical specifications.

Secondary parameters that may vary between substitutes include contact material composition (copper alloy, brass, or phosphor bronze), insulation material formulation (PCT polyester, polyamide nylon, or PBT), contact finish thickness on mating surfaces, post finish composition (tin, tin-lead, or nickel), and overall contact length. These variations remain within acceptable tolerances for functional interchangeability in standard applications.

Compliance parameters including RoHS status, REACH classification, and product status (active versus obsolete) are documented to support procurement and regulatory requirements but do not restrict electrical or mechanical substitution.

Engineering Selection Recommendations

All listed substitute parts maintain functional compatibility with the 2516-6002-UB across core electrical and mechanical parameters. Selection should prioritize active product status and compliance requirements.

For applications requiring RoHS3 compliance, the following parts are recommended: N2516-6002-RB (3M), D2516-6002-AR (3M), 008383016000010 (KYOCERA AVX), 0702461601 through 0702461604 (Molex C-Grid 70246 series), 0878341611 and 0878341641 (Molex C-Grid 87834 series), and 5103308-3 (TE Connectivity AMP-Latch).

For applications where RoHS compliance is not required, 103308-3 (TE Connectivity AMP-Latch) remains available with active product status.

The 3M N2516-6002-RB provides the closest direct replacement, maintaining identical pitch, row spacing, contact dimensions, and operating temperature range while upgrading to ROHS3 compliance and active product status. The 3M D2516-6002-AR offers an alternative within the 3M product family with board-to-cable/wire configuration.

Molex C-Grid series parts (0702461601, 0702461602, 0702461604, 0878341611, 0878341641) provide high-volume availability and ROHS3 compliance. The 0702461602 and 0702461604 variants offer tray packaging with the largest inventory levels.

TE Connectivity AMP-Latch series (103308-3, 5103308-3) provide extended operating temperature range (-65°C to 105°C) compared to the main part specification. The 5103308-3 variant includes RoHS compliance and tray packaging.

Frequently Asked Questions (FAQ)

Q: Can the 2516-6002-UB be directly replaced with N2516-6002-RB?

A: Yes. The N2516-6002-RB maintains identical electrical and mechanical specifications including 16-position configuration, 0.100" pitch, shrouded 4-wall design, through-hole mounting, and solder termination. The primary differences are active product status and ROHS3 compliance. Contact finish on the post changes from tin-lead to tin, which is compatible with standard solder assembly processes.

Q: What is the difference between the Molex C-Grid 70246 variants (0702461601, 0702461602, 0702461604)?

A: These parts are functionally identical in electrical and mechanical specifications. The differences are packaging format (bulk versus tray) and contact finish thickness on the mating surface. Part 0702461601 is supplied in bulk packaging, while 0702461602 and 0702461604 are supplied in tray packaging. The mating contact finish thickness varies: 0702461601 and 0702461602 have 15.0µin and 30.0µin respectively, while 0702461604 has 5.00µin. All three maintain gold plating on mating contacts and tin post finish.

Q: Are there compatibility concerns with different contact materials (copper alloy, brass, phosphor bronze)?

A: No. All substitute parts maintain square contact geometry, gold-plated mating surfaces, and equivalent contact resistance characteristics. Contact material composition (copper alloy, brass, or phosphor bronze) does not affect mating compatibility or electrical performance in standard applications.

Q: Does the insulation material change affect compatibility?

A: No. All substitute parts maintain UL94 V-0 flammability rating and equivalent mechanical strength. Insulation material variations (PCT polyester, polyamide nylon, or PBT) do not affect connector mating, unmating, or electrical performance.

Q: What is the significance of the different operating temperature ranges?

A: The main part 2516-6002-UB specifies -55°C to 105°C. TE Connectivity AMP-Latch parts (103308-3, 5103308-3) extend the lower limit to -65°C. Molex and KYOCERA AVX parts do not specify operating temperature limits in the provided data. For applications requiring operation below -55°C, the TE Connectivity AMP-Latch series is appropriate.

Q: How does the current rating difference between 1.75A and 1A affect selection?

A: The main part and 3M substitutes (N2516-6002-RB, D2516-6002-AR) are rated at 1.75A per contact. The KYOCERA AVX 008383016000010 is rated at 1A per contact. For applications requiring current levels between 1A and 1.75A per contact, verify the specific current requirements before selecting the KYOCERA AVX part. Molex and TE Connectivity parts do not specify current ratings in the provided data.

Q: What packaging options are available?

A: Packaging varies by manufacturer and part number. 3M N2516-6002-RB is supplied in bulk. 3M D2516-6002-AR is supplied in tray. KYOCERA AVX 008383016000010 is supplied in tray. Molex 0702461601 is supplied in bulk; 0702461602, 0702461604, 0878341611 are supplied in tray; 0878341641 is supplied in tray. TE Connectivity 103308-3 is supplied in bulk; 5103308-3 is supplied in tray. Select packaging based on procurement and assembly requirements.

Q: Are all substitute parts REACH compliant?

A: The main part 2516-6002-UB is REACH Affected. All substitute parts are REACH Unaffected except 103308-3, which is REACH Affected. For applications requiring REACH Unaffected status, select from N2516-6002-RB, D2516-6002-AR, 008383016000010, Molex series (0702461601 through 0702461604, 0878341611, 0878341641), or 5103308-3.
