Engineering Selection Recommendations

The Molex 0702462601 is the primary direct equivalent, sharing identical mechanical and electrical specifications with the obsolete 0702462621 while offering active product status and ROHS3 compliance. This part is recommended as the first choice for direct replacement in new designs and production continuity.

For applications requiring RoHS3 compliance and extended operating temperature range, the TE Connectivity AMP-Latch series (103308-6, 103309-6, 5103308-6, 5103309-6, 5104338-6) provides functional compatibility with minor variations in contact post length and insulation height. The 5103308-6 and 5103309-6 variants offer ROHS3 compliance and are available in tube packaging.

The 3M 30326-6002HB offers ROHS3 compliance and operates across -55°C to 105°C, with gold plating on both mating and post contacts. This part is suitable for applications requiring enhanced corrosion resistance.

The Amphenol ICC Quickie™ series (52601-G26-4LF, 52601-S26-4LF, 52601-S26-6LF) provides RoHS-compliant alternatives with phosphor bronze contacts matching the original material specification. The 52601-S26-6LF variant features extended contact post length (0.150") for applications requiring deeper board penetration.

Selection between these alternatives depends on specific compliance requirements, packaging preferences, and contact post length specifications for PCB board thickness accommodation.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0702462601 directly replace the obsolete 0702462621?

A: Yes. The 0702462601 maintains identical pitch (2.54mm), position count (26), row configuration (2), mounting type (through hole), and shrouding specifications. The primary difference is active product status and ROHS3 compliance. Contact finish on the post differs (Tin versus Tin-Lead), which is functionally compatible for solder termination.

Q: What are the key differences between TE Connectivity and Amphenol ICC alternatives?

A: TE Connectivity AMP-Latch series uses brass contacts with operating temperature range -65°C to 105°C and specified current ratings (1A per contact). Amphenol ICC Quickie™ series uses phosphor bronze contacts matching the original material, with unspecified operating temperature and current ratings. Contact post length varies: TE Connectivity standard is 0.120" (3.05mm), while Amphenol ICC offers 0.120" or 0.150" (3.81mm) options.

Q: Are there RoHS compliance differences among substitutes?

A: Yes. The Molex 0702462621 is RoHS non-compliant. The Molex 0702462601 and 3M 30326-6002HB are ROHS3 compliant. TE Connectivity 5103308-6, 5103309-6, and 5104338-6 are ROHS3 compliant. Amphenol ICC Quickie™ series (52601-G26-4LF, 52601-S26-4LF, 52601-S26-6LF) are RoHS compliant. Selection depends on regulatory requirements for the target application.

Q: What packaging options are available?

A: Molex 0702462601 is supplied in bulk packaging. TE Connectivity AMP-Latch series offers bulk (103308-6, 103309-6) and tube (5103308-6, 5103309-6, 5104338-6) packaging. 3M 30326-6002HB is supplied in bulk. Amphenol ICC Quickie™ series is supplied in tray packaging. Packaging selection affects handling, storage, and automated assembly compatibility.

Q: Are contact post length variations significant for PCB compatibility?

A: Yes. The original 0702462621 specifies 0.135" (3.43mm) post length. Substitutes vary: Molex 0702462601 matches at 0.135", TE Connectivity standard is 0.120" (3.05mm), 3M is 0.110" (2.79mm), and Amphenol ICC offers 0.120" or 0.150" (3.81mm). Post length must accommodate PCB thickness and solder fillet requirements. Verify PCB design specifications before selection.

Q: What is the significance of contact finish differences?

A: The original part specifies gold mating contact with tin-lead post finish. Substitutes maintain gold or gold-palladium mating finish for signal integrity. Post finish varies: tin (Molex 0702462601, TE Connectivity, Amphenol ICC) or gold (3M 30326-6002HB). Tin and tin-lead finishes are functionally equivalent for solder termination. Gold post finish provides enhanced corrosion resistance in high-humidity environments.

Q: Can TE Connectivity and Amphenol ICC parts be mixed in the same assembly?

A: Mechanically, yes, as both maintain identical pitch, position count, and shrouding. However, mixing introduces variations in contact material (brass versus phosphor bronze), contact finish, and operating temperature specifications. For consistency and traceability, use a single manufacturer's part throughout an assembly.
