Parts meeting all these criteria are classified as direct substitutes within the EHT series.

Parameter Comparison

Engineering Selection Recommendations

Both the EHT-108-01-SM-D-SM and EHT-108-01-S-D-SM are active production parts from Samtec Inc. with identical electrical and mechanical specifications. Both parts are ROHS3 compliant and carry UL94 V-0 flammability certification, meeting regulatory requirements for industrial and commercial applications. Selection between these parts may be based on inventory availability, lead time, or supply chain considerations, as all functional parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: What determines if a part is a valid substitute for the EHT-108-01-SM-D-SM?

A: A substitute must match all critical parameters including connector type (Header), contact type (Male Pin), position count (16), row configuration (2 rows), pitch (2.00mm), mounting type (Surface Mount), shrouding (Shrouded - 4 Wall), termination (Solder), contact geometry, material composition, and operating specifications. Deviations in any of these parameters disqualify a part as a direct substitute.

Q: Are the EHT-108-01-SM-D-SM and EHT-108-01-S-D-SM mechanically interchangeable?

A: Yes. Both parts share identical mechanical dimensions, including mating contact length (0.120"), insulation height (0.370"), and row spacing (0.079"). They are designed for the same PCB footprint and mating interface.

Q: What is the significance of the shrouded 4-wall design?

A: The 4-wall shrouding provides mechanical guidance and polarization during mating, preventing incorrect connector orientation and protecting contacts from accidental contact. This design is integral to the connector's function and must be maintained in any substitute part.

Q: Can these connectors be used in high-temperature applications?

A: The operating temperature range of -55°C to 125°C supports use in industrial and automotive environments. The Liquid Crystal Polymer insulation material and phosphor bronze contacts maintain performance within this range.

Q: What does ROHS3 compliance indicate?

A: ROHS3 compliance indicates the part meets the Restriction of Hazardous Substances Directive, restricting the use of specific hazardous materials including lead, cadmium, and mercury. This certification is required for many commercial and industrial applications.

Q: Is the MSL rating of 1 significant for storage and handling?

A: An MSL rating of 1 (Unlimited) indicates the part has no moisture sensitivity limitations. Standard storage conditions are sufficient, and no special desiccant packaging or baking procedures are required prior to soldering.
