Engineering Selection Recommendations

For applications currently using the obsolete 52601-G34-4R, the following selection criteria apply:

RoHS Compliance Requirement: If RoHS compliance is mandated, select from 52601-G34-4RLF, 10073456-044LF, 0702463401, 0702463402, or 30334-6002HB. The original 52601-G34-4R is RoHS non-compliant and unsuitable for new designs subject to RoHS directives.

Direct Amphenol ICC (FCI) Replacement: The 52601-G34-4RLF is the direct active equivalent from the same manufacturer and series, maintaining Quickie™ series compatibility with improved RoHS compliance status.

Cross-Manufacturer Alternatives: The Molex 0702463401 and 0702463402 (C-Grid 70246 series) and 3M 30334-6002HB (303 series) provide functionally equivalent solutions with active product status and full RoHS3 compliance. These alternatives are suitable for applications where manufacturer diversity or supply chain redundancy is beneficial.

Termination Consideration: The Molex and 3M alternatives support solder termination only, whereas the Amphenol ICC options support both press-fit and solder termination. Applications requiring press-fit assembly must use 52601-G34-4RLF or 10073456-044LF.

Inventory Availability: The Molex 0702463401 offers the highest current inventory level at 3965 pieces, followed by 3M 30334-6002HB at 2303 pieces, providing supply security for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can the 52601-G34-4R be directly replaced with 52601-G34-4RLF?

A: Yes. The 52601-G34-4RLF is the direct active equivalent from Amphenol ICC (FCI) in the same Quickie™ series. All critical electrical and mechanical parameters are identical. The primary difference is active product status and RoHS compliance.

Q: What is the difference between the Amphenol ICC and Molex alternatives?

A: Both maintain identical connector geometry, pitch, position count, and shrouding. The Molex C-Grid 70246 series (0702463401, 0702463402) differs in insulation material composition (PBT glass-filled vs. thermoplastic) and supports solder termination only. Amphenol ICC options support both press-fit and solder termination.

Q: Are the 0702463401 and 0702463402 interchangeable?

A: Yes. Both are Molex C-Grid 70246 series parts with identical connector specifications. The difference is contact finish thickness on the mating surface: 0702463401 has 15.0µin (0.38µm) gold finish, while 0702463402 has 30.0µin (0.76µm) gold finish. Both meet the core substitution parameters.

Q: Can I use the 3M 30334-6002HB as a substitute?

A: Yes. The 3M 303 series 30334-6002HB meets all critical substitution parameters. It features brass contact material instead of phosphor bronze and includes operating temperature specification (-55°C ~ 105°C) and current rating (1A) not provided for other alternatives. It is suitable for applications requiring these environmental specifications.

Q: Does insulation color affect compatibility?

A: No. Insulation color is a visual identifier only and does not affect electrical or mechanical function. The 10073456-044LF features blue insulation while all other alternatives are black. This is a cosmetic difference with no impact on connector performance.

Q: What packaging options are available?

A: 52601-G34-4RLF is supplied in Tray packaging. The Molex alternatives (0702463401, 0702463402) and 3M 30334-6002HB are supplied in Bulk packaging. Packaging selection depends on assembly process requirements and inventory management practices.

Q: Are all alternatives RoHS compliant?

A: The original 52601-G34-4R is RoHS non-compliant. All listed alternatives (52601-G34-4RLF, 10073456-044LF, 0702463401, 0702463402, 30334-6002HB) are RoHS Compliant or ROHS3 Compliant, suitable for applications subject to RoHS directives.
