SS-105-S-2 Equivalent & Substitute Parts

Part Overview

The SS-105-S-2 is a 5-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 gold-plated mating contacts and tin-plated posts, operating across -55°C to 125°C. The product is active and ROHS3 compliant with MSL 1 rating. Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling component interchangeability in applications where the original part may be unavailable or inventory constraints exist.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SS-105-S-2 is determined by the following critical parameters:

• 5-position configuration with 0.100" (2.54mm) pitch spacing
• Female socket receptacle connector type for board-to-board mating
• Through-hole solder termination
• Gold-plated mating contacts
• Circular contact geometry
• PBT glass-filled insulation material
• ROHS3 compliance

The substitute part SMC-1-05-1-GT meets these core electrical and mechanical requirements, enabling functional equivalence in applications requiring a 5-position 2.54mm pitch socket connector with gold mating contacts and through-hole mounting.

Parameter Comparison

Engineering Selection Recommendations

Both the SS-105-S-2 and SMC-1-05-1-GT are active products with ROHS3 compliance and MSL 1 ratings, suitable for applications requiring 5-position 2.54mm pitch socket connectors. The primary distinction is the operating temperature range: the SS-105-S-2 operates to 125°C, while the SMC-1-05-1-GT operates to 105°C. Selection should be based on the specific thermal requirements of the application. The SMC-1-05-1-GT includes a UL94 V-0 flammability rating and specified current/voltage ratings (3A, 100V/150VDC), whereas the SS-105-S-2 does not provide these specifications in the available data. Both connectors utilize PBT glass-filled insulation and circular contact geometry, ensuring mechanical and electrical compatibility in board-to-board configurations.

Frequently Asked Questions (FAQ)

Q: Can the SMC-1-05-1-GT replace the SS-105-S-2 in all applications?

A: Substitution is valid for applications operating at or below 105°C. Applications requiring operation above 105°C must use the SS-105-S-2 due to its extended temperature range to 125°C.

Q: What is the difference in contact finish thickness between these parts?

A: The SS-105-S-2 specifies 10.0µin (0.25µm) gold plating thickness, while the SMC-1-05-1-GT specifies flash gold plating. Both provide gold mating contacts; the thickness difference may affect contact durability in high-cycle mating applications.

Q: Are the packaging formats interchangeable?

A: The SS-105-S-2 is supplied in tube packaging, while the SMC-1-05-1-GT is supplied in bulk packaging. Packaging format does not affect connector functionality but may impact handling and storage procedures.

Q: Do both connectors support the same mating cycles?

A: The provided specifications do not include mating cycle ratings for either connector. Consult manufacturer datasheets for mechanical life specifications if mating cycle performance is critical to the application.

Q: What contact materials are used in each connector?

A: The SS-105-S-2 uses beryllium copper contacts, while the SMC-1-05-1-GT uses copper alloy contacts. Both materials are suitable for 2.54mm pitch socket applications with gold plating.
