Engineering Selection Recommendations

Active Product Status Priority: All listed substitute parts maintain active product status with current manufacturing support, eliminating obsolescence risk associated with the 3M 2516-60K2UG.

RoHS Compliance Considerations: The original 3M 2516-60K2UG is RoHS non-compliant. For applications requiring RoHS3 compliance, select from: 008383016000010, 0702461601, 0702461602, 0702461604, 0878341611, 0878341641, 5103309-3, or 5104338-3.

For applications where RoHS non-compliance is acceptable or legacy compliance is required, 103309-3 and 5103308-3 provide alternative options with extended operating temperature range (-65°C to 105°C).

Packaging Considerations: Bulk packaging (0702461601, 0878341611) suits high-volume production. Tray packaging (008383016000010, 0702461602, 0702461604, 0878341641, 5103308-3) supports moderate-volume assembly. Tube packaging (103309-3, 5103309-3, 5104338-3) accommodates lower-volume or automated insertion processes.

Contact Finish Post Material: Tin-Lead finish (103309-3) matches the original specification. Tin finish alternatives (0702461601, 0702461602, 0702461604, 0878341611, 0878341641, 5103308-3, 5103309-3, 5104338-3) provide equivalent solder compatibility. Nickel finish (008383016000010) offers enhanced corrosion resistance.

Temperature Range: TE Connectivity AMP-Latch series (103309-3, 5103308-3, 5103309-3, 5104338-3) extends minimum operating temperature to -65°C, exceeding the original -55°C specification. All alternatives maintain the 105°C maximum.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for the 3M 2516-60K2UG?

A: Yes, all listed parts are functionally equivalent within the defined parameter tolerances. Mechanical fit, electrical performance, and connector interface compatibility are maintained across all substitutes. Verify packaging requirements and compliance certifications for your specific application before selection.

Q: What is the primary reason the 3M 2516-60K2UG is obsolete?

A: The 3M 2516-60K2UG is classified as obsolete by the manufacturer. Active alternatives from Molex, TE Connectivity, and KYOCERA AVX provide equivalent functionality with ongoing production support and compliance certifications.

Q: Are there differences in contact material between the original and substitutes?

A: Yes. The original uses Copper Alloy contacts. Substitutes employ Copper Alloy (Molex 0878341611, 0878341641), Phosphor Bronze (Molex 0702461601, 0702461602, 0702461604), or Brass (TE Connectivity and KYOCERA AVX). All materials are compatible with standard PCB assembly and solder processes.

Q: Which substitute offers the best RoHS compliance?

A: KYOCERA AVX 008383016000010, Molex 0702461601/0702461602/0702461604/0878341611/0878341641, and TE Connectivity 5103309-3 and 5104338-3 are ROHS3 compliant. Select based on packaging and availability requirements.

Q: Does packaging type affect electrical or mechanical performance?

A: No. Bulk, Tray, and Tube packaging options provide identical connector specifications. Packaging selection depends on production volume, assembly automation, and inventory management requirements.

Q: What is the current rating difference between the original and substitutes?

A: The original 3M 2516-60K2UG is rated at 1.75A. Most substitutes are rated at 1A per contact, which is acceptable for applications within this current envelope. KYOCERA AVX 008383016000010 specifies 1A. Verify application current requirements before selection.

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

A: Yes. All substitute parts maintain identical mating pitch (0.100"), shrouding geometry, and push-pull fastening. Connectors from different manufacturers are mechanically and electrically interchangeable within a single assembly.

Q: Which substitute has the widest operating temperature range?

A: TE Connectivity AMP-Latch series (103309-3, 5103308-3, 5103309-3, 5104338-3) operates from -65°C to 105°C, extending the minimum temperature 10°C below the original specification of -55°C to 105°C.
