Engineering Selection Recommendations

All listed substitute parts maintain functional equivalence to the 52601-G34-4 across core mechanical and electrical parameters. Selection should prioritize product status and regulatory compliance:

Molex C-Grid 70246 Series (0702463401, 0702463402, 0702463404): These parts are active products with ROHS3 compliance, offering long-term availability and supply chain stability. The three variants differ in contact finish thickness (15.0µin, 30.0µin, and 5.00µin respectively), allowing selection based on specific contact resistance or durability requirements. All three are functionally interchangeable with the obsolete 52601-G34-4.

3M 303 Series (30334-6002HB): This part is an active product with ROHS3 compliance and includes specified operating temperature range (-55°C ~ 105°C) and current rating (1A). The brass contact material and flash gold finish provide an alternative to phosphor bronze construction. This option is suitable for applications requiring documented thermal and electrical specifications.

The 52601-G34-4 is RoHS non-compliant, whereas all substitute parts meet ROHS3 requirements, making them preferable for new designs and regulated applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0702463401, 0702463402, and 0702463404 be used interchangeably with the Amphenol ICC 52601-G34-4?

A: Yes. All three Molex variants share identical connector type, position count, pitch, mounting method, and shrouding. Differences in contact finish thickness do not affect mechanical or electrical compatibility in standard applications. Selection between the three should be based on specific contact resistance or durability requirements for your application.

Q: What is the difference between the three Molex substitute parts?

A: The primary difference is contact finish thickness on the mating surface: 0702463401 has 15.0µin, 0702463402 has 30.0µin, and 0702463404 has 5.00µin. All three use gold plating over phosphor bronze with tin-plated posts. The thicker finishes (0702463401 and 0702463402) may provide enhanced durability in high-cycle mating applications.

Q: Is the 3M 30334-6002HB compatible with the 52601-G34-4?

A: Yes. The 3M part meets all core substitution criteria: 34-position header, 2.54mm pitch, through-hole solder termination, shrouded 4-wall construction, and push-pull fastening. The brass contact material and flash gold finish are functionally equivalent to the phosphor bronze and gold construction of the original part. The 3M variant includes specified operating temperature and current rating documentation.

Q: Why is the original 52601-G34-4 marked as obsolete?

A: Obsolescence indicates the part is no longer manufactured by Amphenol ICC. Active substitute parts from Molex and 3M provide equivalent functionality with current production support and modern compliance certifications (ROHS3).

Q: Are there packaging differences between the substitute parts?

A: Yes. The Molex 0702463401 and 0702463402 are supplied in bulk packaging, while 0702463404 is supplied in tray packaging. The 3M 30334-6002HB is supplied in bulk packaging. Packaging does not affect connector performance or compatibility.

Q: Do all substitute parts meet RoHS requirements?

A: All listed substitute parts are ROHS3 compliant. The original 52601-G34-4 is RoHS non-compliant. For applications subject to RoHS regulations, any of the substitute parts is required.

Q: What is the current rating for the 52601-G34-4?

A: The current rating is not specified in the original part documentation. The 3M 30334-6002HB specifies 1A per contact. For applications requiring documented current specifications, the 3M part provides this information.
