Engineering Selection Recommendations

Both the Amphenol ICC 68459-472 and Samtec TSW-136-25-S-D-RA are active production components meeting UL94 V-0 flammability requirements and MSL 1 moisture sensitivity specifications. The primary distinction is RoHS compliance status: the Samtec part is ROHS3 compliant, while the Amphenol part is RoHS non-compliant. Selection between these parts should be based on regulatory requirements for the end application. The Samtec TSW-136-25-S-D-RA additionally provides a documented operating temperature range of -55°C to 125°C. Minor dimensional variations exist in contact post length and insulation height; these differences do not affect functional compatibility in standard board-to-board connector applications where mating pitch and position count are the primary design constraints.

Frequently Asked Questions (FAQ)

Q: Can the Samtec TSW-136-25-S-D-RA directly replace the Amphenol ICC 68459-472 in existing PCB designs?

A: Yes, for applications where RoHS compliance is not mandated. Both connectors share identical mating pitch (0.100"), position count (72), row configuration (2 rows), and mounting orientation (through-hole, right-angle). The connectors are mechanically and electrically compatible for board-to-board interconnection.

Q: What is the significance of the RoHS compliance difference?

A: RoHS3 compliance (Samtec part) indicates the component meets Restriction of Hazardous Substances regulations. If your application or end market requires RoHS certification, the Samtec part is the appropriate selection. The Amphenol part does not carry this certification.

Q: Are there dimensional differences that affect PCB layout?

A: Minor differences exist in contact post length (0.150" vs. 0.100") and insulation height (0.190" vs. 0.219"). These variations do not affect PCB footprint or mating interface dimensions. Verify solder joint clearances and component stacking height if space constraints are critical.

Q: What is the difference between tin and gold contact finishes?

A: The Amphenol part uses tin mating contact finish (100.0µin thickness), while the Samtec part uses gold mating contact finish (30.0µin thickness). Both finishes provide adequate corrosion resistance for standard applications. Gold offers superior contact reliability in low-force or low-current applications; tin is suitable for general-purpose board-to-board connections.

Q: Are both parts suitable for high-temperature applications?

A: The Samtec TSW-136-25-S-D-RA specifies an operating temperature range of -55°C to 125°C. The Amphenol part does not provide an operating temperature specification in the available data. For applications requiring documented temperature performance, the Samtec part is the specified choice.
