Engineering Selection Recommendations

All three parts maintain active product status and ROHS3 compliance, confirming ongoing manufacturer support and regulatory alignment. The HTST-110-01-LM-DV and HTST-110-01-L-DV are both members of the HTST series with identical electrical and mechanical specifications. The HTSS-110-01-L-DV belongs to the HTSS series and is compatible for board-to-board or cable applications, with all critical mating parameters preserved.

Selection between HTST-110-01-LM-DV and HTST-110-01-L-DV depends on supply availability and MSL requirements for storage and handling. The HTSS-110-01-L-DV provides an alternative within the Samtec Flex Stack connector family when HTST variants are unavailable. All three parts are suitable for applications requiring 20-position, 2.54mm pitch surface mount headers with push-pull fastening and UL94 V-0 rated insulation.

Frequently Asked Questions (FAQ)

Q: Can HTST-110-01-L-DV be used as a direct replacement for HTST-110-01-LM-DV?

A: Yes. Both parts share identical electrical and mechanical specifications, including 20 positions, 2.54mm pitch, 3.4A per contact current rating, and -55°C to 125°C operating temperature. The difference in MSL rating (Not Applicable vs. 1 Unlimited) does not affect functional interchangeability.

Q: What is the difference between HTST and HTSS series connectors?

A: The HTST series is designated for board-to-cable/wire applications, while the HTSS series supports board-to-board or cable configurations. For the 110-01 connector, all critical mating parameters remain identical, making them functionally interchangeable in applications where the connection style is compatible.

Q: Are all three parts RoHS compliant?

A: Yes. HTST-110-01-LM-DV, HTST-110-01-L-DV, and HTSS-110-01-L-DV are all ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What does MSL rating mean, and does it affect part selection?

A: MSL (Moisture Sensitivity Level) indicates storage and handling requirements. HTST-110-01-LM-DV has no MSL requirement, while HTST-110-01-L-DV and HTSS-110-01-L-DV are rated MSL 1 (Unlimited), meaning they can be stored indefinitely without special moisture control. This does not affect electrical or mechanical performance.

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

A: Yes. All three parts are rated for -55°C to 125°C operating temperature, supporting applications across this full range.

Q: What is the current-carrying capacity of these connectors?

A: HTST-110-01-LM-DV and HTST-110-01-L-DV are rated at 3.4A per contact. HTSS-110-01-L-DV does not specify a current rating in the provided data.
