HSS-102-TT-2 Equivalent & Substitute Parts

Part Overview

The HSS-102-TT-2 is a 2-position receptacle connector manufactured by Samtec Inc., designed for board-to-board applications with 0.100" (2.54mm) pitch through-hole mounting. This connector features female socket contacts with tin plating on the mating surface and is constructed from Liquid Crystal Polymer (LCP) insulation material. The part maintains Active product status and is ROHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity protection.

Substitute parts become necessary when inventory constraints, lead time requirements, or design flexibility considerations require alternative sourcing while maintaining functional equivalence across critical electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HSS-102-TT-2 is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (2)
• Pitch specification (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Termination type (Solder)
• Mating contact finish (Tin)
• Insulation height (0.100" / 2.54mm)
• Contact post length (0.125" / 3.18mm)
• Operating temperature range (-55°C ~ 125°C)
• Compliance certifications (ROHS3, REACH Unaffected)

The SS-102-TT-2 meets all substitution criteria as a manufacturer-recommended equivalent, maintaining identical functional and mechanical specifications while differing only in insulation material composition and series designation.

Parameter Comparison

Engineering Selection Recommendations

Both HSS-102-TT-2 and SS-102-TT-2 maintain Active product status with identical ROHS3 compliance and REACH Unaffected certification. The parts are functionally equivalent across all specified electrical and mechanical parameters, including connector type, contact configuration, pitch, mounting method, and operating temperature range.

Selection between these parts should be based on inventory availability, lead time requirements, and design documentation flexibility. Both parts satisfy identical compliance and certification requirements for applications requiring 2-position, 0.100" pitch receptacle connectors with through-hole solder termination.

Frequently Asked Questions (FAQ)

Q: Can SS-102-TT-2 be used as a direct replacement for HSS-102-TT-2?

A: Yes. Both parts are 2-position receptacle connectors with identical pitch (0.100"), mounting type (through-hole), termination method (solder), and operating temperature range (-55°C ~ 125°C). They maintain equivalent mechanical and electrical specifications.

Q: What is the difference between HSS-102-TT-2 and SS-102-TT-2?

A: The primary differences are series designation (HSS vs. SS) and insulation material composition. HSS-102-TT-2 uses Liquid Crystal Polymer (LCP) insulation, while SS-102-TT-2 uses Polybutylene Terephthalate (PBT) with glass filler. Both materials support the same operating temperature range and compliance requirements.

Q: Are both parts ROHS3 compliant?

A: Yes. Both HSS-102-TT-2 and SS-102-TT-2 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing.

Q: What is the MSL rating for these connectors?

A: Both parts carry MSL 1 rating, indicating unlimited moisture sensitivity protection. No special moisture control measures are required during storage or handling.

Q: Do these connectors support the same contact materials?

A: HSS-102-TT-2 uses Beryllium Copper and Brass contacts, while SS-102-TT-2 uses Beryllium Copper contacts. Both configurations support identical mating contact finish (tin) and post contact specifications.
