Engineering Selection Recommendations

The 52601-G16-6LF is the direct Amphenol ICC equivalent with active product status and RoHS compliance, making it the primary substitute for the obsolete 52601-G16-6. Both parts share identical electrical and mechanical specifications with only packaging and RoHS certification differences.

The Molex C-Grid series (0702461601, 0702461602, 0702461604) provides cross-manufacturer alternatives with ROHS3 compliance and higher inventory availability. These parts maintain all critical functional parameters and are suitable for applications requiring active product support and regulatory compliance.

The 3M 2500 series (N2516-6002-RB) offers an alternative from a third manufacturer with ROHS3 compliance and specified operating temperature range (-55°C ~ 105°C) and current rating (1.75A). This part is suitable for applications with defined thermal and electrical requirements.

Selection should prioritize active product status and RoHS compliance for new designs. The 52601-G16-6LF provides continuity with the original Amphenol ICC design, while Molex and 3M alternatives offer broader supply chain options and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the 52601-G16-6LF directly replace the obsolete 52601-G16-6?

A: Yes. The 52601-G16-6LF maintains identical electrical and mechanical specifications including pitch, position count, shrouding, mounting type, and termination method. The primary differences are active product status and RoHS compliance.

Q: What are the key differences between Amphenol ICC and Molex substitutes?

A: All parts meet the same core functional requirements. Molex C-Grid series (0702461601, 0702461602, 0702461604) differ in insulation material composition (PBT glass-filled versus thermoplastic) and contact finish thickness specifications. The Molex parts carry ROHS3 compliance and higher inventory levels.

Q: Are there differences between Molex part numbers 0702461601, 0702461602, and 0702461604?

A: These parts are functionally equivalent. Differences exist in packaging format (bulk versus tray) and contact finish thickness on the mating surface (15.0µin, 30.0µin, and 5.00µin respectively). All three maintain identical pitch, position count, and core electrical characteristics.

Q: What is the significance of the 3M N2516-6002-RB part number?

A: The 3M part provides a third-manufacturer option with specified operating temperature range (-55°C ~ 105°C) and current rating (1.75A). It uses copper alloy contact material and PCT-based insulation material, maintaining all critical mechanical and electrical compatibility parameters.

Q: Does packaging format affect functional compatibility?

A: No. Packaging differences (bulk, tray) do not affect electrical or mechanical performance. Selection should be based on procurement and assembly process requirements.

Q: Are all substitute parts RoHS compliant?

A: The 52601-G16-6 is RoHS non-compliant. The 52601-G16-6LF is RoHS Compliant. The Molex parts (0702461601, 0702461602, 0702461604) and 3M part (N2516-6002-RB) are all ROHS3 Compliant. RoHS compliance should be verified against specific design and regulatory requirements.

Q: What contact finish options are available across substitute parts?

A: All parts feature gold mating contact finish with tin post finish. Mating contact finish thickness varies: 30.0µin (52601-G16-6, 52601-G16-6LF, N2516-6002-RB), 15.0µin (0702461601), 30.0µin (0702461602), and 5.00µin (0702461604). These variations do not affect functional interchangeability.
