Engineering Selection Recommendations

Both the Amphenol ICC 68452-472 and Samtec Inc. TSW-136-25-S-D-RA are active production components meeting UL94 V-0 flammability requirements and MSL 1 specifications. The primary differentiation factor is regulatory compliance: the Samtec TSW-136-25-S-D-RA is ROHS3 compliant, while the Amphenol ICC 68452-472 is RoHS non-compliant. Selection between these parts should be based on regulatory requirements applicable to the end application. Both components are in active stock with comparable inventory levels. Minor dimensional variations exist in contact length and insulation height; these differences do not affect functional equivalence for standard board-to-board interconnect applications.

Frequently Asked Questions (FAQ)

Q: Can the Samtec TSW-136-25-S-D-RA be used as a direct replacement for the Amphenol ICC 68452-472?

A: Yes. Both components share identical electrical and mechanical specifications for connector type, contact configuration, pitch spacing, mounting method, and termination. The Samtec part offers expanded style compatibility (Board to Board or Cable) compared to the Amphenol part (Board to Board only).

Q: What are the key differences between these two parts?

A: The primary differences are contact finish composition (Tin vs. Gold), contact finish thickness, insulation material specification, operating temperature range documentation, and RoHS compliance status. The Samtec part provides ROHS3 compliance and documented operating temperature range (-55°C ~ 125°C), while the Amphenol part does not specify these parameters.

Q: Are there dimensional compatibility concerns when substituting these parts?

A: Minor dimensional variations exist. The Samtec TSW-136-25-S-D-RA has a shorter mating contact length (0.320" vs. 0.380") and slightly taller insulation height (0.219" vs. 0.190"). These differences are within standard connector design tolerances and do not affect functional compatibility in typical board-to-board applications.

Q: Which part should be selected for RoHS-regulated applications?

A: The Samtec Inc. TSW-136-25-S-D-RA is ROHS3 compliant and is the appropriate selection for applications subject to RoHS directives. The Amphenol ICC 68452-472 is RoHS non-compliant.

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

A: Both components meet UL94 V-0 flammability requirements and carry MSL 1 (Unlimited) moisture sensitivity ratings, indicating suitability for standard industrial and commercial applications. The Samtec part provides documented operating temperature range (-55°C ~ 125°C), which may be relevant for extended temperature applications.
