Key Parameters

Substitute Part Grouping Explanation

The HTST-110-01-L-D qualifies as a direct substitute for the HTST-110-01-S-D based on the following critical parameters:

Matching Parameters (Substitution Basis):

• Manufacturer: Samtec Inc.
• Series: Flex Stack, HTST
• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 20
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Shrouding: Shrouded - 4 Wall
• Contact Length - Mating: 0.250" (6.35mm)
• Contact Length - Post: 0.115" (2.92mm)
• Overall Contact Length: 0.480" (12.19mm)
• Insulation Height: 0.350" (8.89mm)
• Contact Shape: Square
• Contact Material: Phosphor Bronze
• Insulation Material: Liquid Crystal Polymer (LCP)
• Current Rating: 3.4A per Contact
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Differing Parameter:

• Contact Finish Thickness - Mating: HTST-110-01-S-D specifies 30.0µin (0.76µm); HTST-110-01-L-D specifies 10.0µin (0.25µm)

Both parts maintain identical electrical and mechanical form factors, allowing direct substitution in applications where the mating contact gold plating thickness differential does not impose specific durability or wear requirements.

Parameter Comparison

Engineering Selection Recommendations

Both HTST-110-01-S-D and HTST-110-01-L-D are active production parts with ROHS3 compliance and UL94 V-0 flammability certification. The parts are functionally equivalent for standard board-to-cable interconnection applications within the specified operating temperature range of -55°C to 125°C.

The primary distinction between these parts is the mating contact gold plating thickness. The HTST-110-01-S-D provides 30.0µin (0.76µm) thickness, while the HTST-110-01-L-D provides 10.0µin (0.25µm) thickness. Both maintain identical electrical performance, current rating of 3.4A per contact, and mechanical form factor.

Selection between these parts should be based on application-specific requirements regarding contact durability, mating cycle expectations, and environmental exposure. Both parts satisfy standard industrial connector specifications and regulatory requirements.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical connector type, position count, pitch, mounting method, and electrical ratings. The only difference is mating contact gold plating thickness (30.0µin versus 10.0µin). Substitution is valid for applications where this plating thickness differential does not impose specific durability requirements.

Q: What is the significance of the contact finish thickness difference?

A: Contact finish thickness affects the durability of the mating surface under repeated connection cycles and environmental exposure. The HTST-110-01-S-D with 30.0µin thickness provides greater plating reserve, while the HTST-110-01-L-D with 10.0µin thickness is suitable for standard industrial applications with moderate mating cycle expectations.

Q: Are both parts RoHS compliant?

A: Yes. Both HTST-110-01-S-D and HTST-110-01-L-D are ROHS3 compliant and carry UL94 V-0 flammability certification.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without special moisture control requirements.

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

A: Yes. Both parts are rated for operating temperatures from -55°C to 125°C, suitable for industrial and commercial temperature environments.

Q: What is the current handling capacity per contact?

A: Both parts are rated for 3.4A per contact, providing consistent electrical performance across the 20-position connector.
