Substitute Part Grouping Explanation

Substitution eligibility for the 52601-G34-4LF is determined by strict equivalence across the following critical parameters:

Connector Type: Header
Contact Type: Male Pin
Number of Positions: 34
Number of Rows: 2
Pitch - Mating: 0.100" (2.54mm)
Row Spacing - Mating: 0.100" (2.54mm)
Shrouding: Shrouded - 4 Wall
Mounting Type: Through Hole
Termination: Solder
Fastening Type: Push-Pull
Contact Shape: Square
Material Flammability Rating: UL94 V-0

All three substitute parts (0702463401, 0702463404, and 30334-6002HB) meet these core electrical and mechanical requirements. Variations in contact length, contact finish thickness, insulation material composition, and packaging format do not preclude substitution when these primary parameters are maintained.

Engineering Selection Recommendations

All three substitute parts maintain active product status and meet UL94 V-0 flammability requirements. The Molex parts (0702463401 and 0702463404) are ROHS3 compliant, while the 3M part (30334-6002HB) is ROHS3 compliant and provides an operating temperature range of -55°C to 105°C. The primary distinction between substitute options is packaging format: 0702463401 is supplied in bulk packaging, 0702463404 in tray packaging, and 30334-6002HB in bulk packaging. Selection should be based on inventory availability, packaging requirements, and compliance certifications applicable to the end application.

Frequently Asked Questions (FAQ)

Q: Can 0702463401, 0702463404, and 30334-6002HB be used interchangeably with 52601-G34-4LF?

A: Yes. All substitute parts maintain identical connector type, contact type, position count, row configuration, pitch, shrouding, mounting type, termination method, and fastening type. These parts are electrically and mechanically equivalent for board-to-board and cable connection applications.

Q: What are the differences in contact length between the main part and substitutes?

A: The 52601-G34-4LF has a mating contact length of 0.230" (5.84mm) and post length of 0.120" (3.05mm). The Molex substitutes (0702463401 and 0702463404) have mating contact length of 0.240" (6.10mm) and post length of 0.135" (3.43mm). The 3M substitute (30334-6002HB) has mating contact length of 0.236" (6.00mm) and post length of 0.110" (2.79mm). These variations remain within acceptable tolerance for standard PCB applications.

Q: Are there compliance differences between the main part and substitutes?

A: The main part is RoHS Compliant. All three substitutes are ROHS3 Compliant, which represents a higher compliance standard. The 3M part additionally specifies an operating temperature range of -55°C to 105°C. All parts maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: What packaging options are available?

A: The main part 52601-G34-4LF is supplied in tray packaging. Substitute 0702463401 is available in bulk packaging. Substitute 0702463404 is available in tray packaging. Substitute 30334-6002HB is available in bulk packaging. Packaging selection should align with procurement and assembly requirements.

Q: Do the insulation material differences affect substitution eligibility?

A: No. The main part uses thermoplastic insulation, while substitutes use polybutylene terephthalate (PBT) with glass filling. Both material types meet UL94 V-0 flammability requirements and are suitable for the specified connector application.

Q: What is the current rating for these connectors?

A: The 3M part (30334-6002HB) specifies a current rating of 1A. The main part and Molex substitutes do not provide current rating specifications in the available data.
