Engineering Selection Recommendations

Primary Substitutes (Tin-Plated Contact Finish)

The TE Connectivity 5-146254-8 and Amphenol ICC 67996-416HLF are direct functional equivalents with tin-plated mating contacts matching the Molex 0702800596 finish specification. Both are active production parts with RoHS compliance. The 5-146254-8 operates within -65°C to 105°C, while the 67996-416HLF extends to -65°C to 125°C, providing broader thermal operating range.

Gold-Plated Contact Alternatives

For applications requiring enhanced corrosion resistance or lower contact resistance, the TE Connectivity AMPMODU Mod II series (5-146255-8, 5-146256-8, 5-146257-8) and Amphenol ICC BERGSTIK® II series (67996-116HLF, 67996-216HLF, 67997-116HLF) offer gold-plated mating surfaces. These parts maintain the same 16-position, 2.54mm pitch configuration and are ROHS3 compliant or RoHS compliant. Operating temperature ranges extend to -65°C to 105°C (TE Connectivity) or -65°C to 130°C (Amphenol ICC).

Compliance Considerations

The Molex 0702800596 is ROHS3 compliant. The 3M 2316-6121-TG is RoHS non-compliant and should not be selected for applications requiring RoHS certification. All TE Connectivity and Amphenol ICC alternatives meet RoHS requirements.

Obsolete Part Status

The TE Connectivity 5-146268-8 is marked obsolete and should not be selected for new designs despite current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can I substitute the Molex 0702800596 with any of the listed alternatives?

A: All listed active production parts are mechanically and electrically interchangeable based on matching 16-position, 2.54mm pitch configuration, through-hole solder termination, and push-pull fastening. Contact finish differences (tin vs. gold) do not affect mechanical fit. Verify operating temperature requirements for your application.

Q: What is the difference between tin-plated and gold-plated contact finishes?

A: Tin-plated contacts (Molex 0702800596, TE Connectivity 5-146254-8, Amphenol ICC 67996-416HLF) provide standard corrosion resistance for general-purpose applications. Gold-plated contacts offer superior corrosion resistance and lower contact resistance, beneficial for low-signal applications or high-reliability requirements. Both finishes are mechanically compatible.

Q: Why does the 3M 2316-6121-TG show RoHS non-compliant status?

A: The 3M 2316-6121-TG does not meet RoHS certification requirements. It should only be selected for applications where RoHS compliance is not mandated.

Q: What is the significance of operating temperature range differences?

A: The Molex 0702800596 does not specify an operating temperature range. Substitutes with defined ranges (-65°C to 105°C or -65°C to 130°C) provide documented thermal performance. Select a substitute with operating temperature range that encompasses your application environment.

Q: Is the TE Connectivity 5-146268-8 suitable for new designs?

A: No. The 5-146268-8 is marked obsolete and should not be used for new product designs. Select from active production alternatives instead.

Q: How do contact length specifications affect substitution?

A: Contact length variations (ranging from 0.440" to 0.505" overall length) reflect different insulation heights and post lengths. These differences do not affect mechanical interchangeability on standard PCB layouts but may impact clearance in space-constrained applications. Verify PCB hole depth and component spacing before substitution.

Q: What packaging options are available?

A: The Molex 0702800596 is supplied in bulk packaging. Substitute parts are available in bulk (TE Connectivity), bag (Amphenol ICC BERGSTIK® II series), or unspecified packaging. Confirm packaging requirements for your procurement process.
