Key Parameters

Substitute Part Grouping Explanation

The HTSS-120-01-F-D has one manufacturer-recommended substitute: HTST-120-01-F-D. Substitution eligibility is determined by the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (40)
• Number of rows (2)
• Pitch - mating (0.100" / 2.54mm)
• Row spacing - mating (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Contact material (Phosphor Bronze)
• Insulation material (Liquid Crystal Polymer)
• Operating temperature range (-55°C ~ 125°C)
• Material flammability rating (UL94 V-0)
• RoHS compliance (ROHS3 Compliant)

The substitute part maintains electrical and mechanical compatibility through identical specifications in these critical parameters. The primary difference lies in the connector series designation (HTST versus HTSS) and application style (Board to Cable/Wire versus Board to Board or Cable).

Parameter Comparison

Engineering Selection Recommendations

Both the HTSS-120-01-F-D and HTST-120-01-F-D are active production parts from Samtec Inc. with identical electrical and mechanical specifications for critical connector parameters. Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial and commercial applications.

The HTST-120-01-F-D provides a specified current rating of 3.4A per contact, whereas the HTSS-120-01-F-D does not include this specification. The HTST-120-01-F-D is designated for board-to-cable/wire applications, while the HTSS-120-01-F-D supports board-to-board or cable configurations. Selection between these parts should be based on application requirements and connector mating partner specifications.

Frequently Asked Questions (FAQ)

Q: Can HTST-120-01-F-D be used as a direct replacement for HTSS-120-01-F-D?

A: Both parts share identical electrical and mechanical specifications for connector type, position count, pitch, row spacing, mounting method, shrouding, termination, contact materials, insulation material, operating temperature range, and flammability rating. The primary difference is application style designation. Compatibility depends on the mating connector and application requirements.

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

A: The HTSS series is designated for board-to-board or cable applications, while the HTST series is designated for board-to-cable/wire applications. Both series maintain identical physical and electrical characteristics for the 40-position, 2.54mm pitch configuration.

Q: Are both parts RoHS compliant?

A: Yes, both HTSS-120-01-F-D and HTST-120-01-F-D are ROHS3 compliant and carry UL94 V-0 flammability certification.

Q: What is the operating temperature range for these connectors?

A: Both parts operate across the temperature range of -55°C to 125°C.

Q: Does the HTST-120-01-F-D provide a current rating specification?

A: Yes, the HTST-120-01-F-D is rated for 3.4A per contact. The HTSS-120-01-F-D does not include a specified current rating in the provided data.

Q: What is the pitch specification for these 40-position headers?

A: Both connectors feature a 0.100" (2.54mm) mating pitch with 0.100" (2.54mm) row spacing, standard for this connector category.
