SS-109-S-2 Equivalent & Substitute Parts

Part Overview

The SS-109-S-2 is a 9-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, with an operating temperature range of -55°C to 125°C. The part is currently active in production and ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across connector pitch, position count, mounting type, and contact configuration.

Key Parameters

Substitute Part Grouping Explanation

The HSS-109-S-2 qualifies as a substitute for the SS-109-S-2 based on the following matched parameters:

• 9-position receptacle configuration
• 0.100" (2.54mm) mating pitch
• Single-row layout
• Through-hole solder termination
• Gold-plated mating contacts with 10.0µin (0.25µm) thickness
• Black polyester insulation
• 0.100" (0.254mm) insulation height
• 0.125" (3.18mm) contact post length
• -55°C to 125°C operating temperature range
• ROHS3 compliance
• MSL 1 (Unlimited) moisture sensitivity rating

Substitution is valid where these core electrical and mechanical parameters are maintained across both parts.

Parameter Comparison

Engineering Selection Recommendations

Both the SS-109-S-2 and HSS-109-S-2 are active production parts with ROHS3 compliance and identical electrical and mechanical specifications for mating pitch, position count, contact configuration, and operating temperature range. Selection between these parts may be based on insulation material differences: the SS-109-S-2 uses polybutylene terephthalate (PBT) with glass fill, while the HSS-109-S-2 uses liquid crystal polymer (LCP). Contact material composition also differs, with the HSS-109-S-2 incorporating brass in addition to beryllium copper. Both parts maintain equivalent performance within the specified operating parameters and are suitable for direct substitution in board-to-board connector applications.

Frequently Asked Questions (FAQ)

Q: What determines if HSS-109-S-2 can substitute for SS-109-S-2?

A: Substitution is valid when the connector maintains identical mating pitch (0.100"), position count (9), row configuration (1 row), mounting type (through-hole), termination method (solder), contact finish (gold), and operating temperature range (-55°C to 125°C). Both parts meet these criteria.

Q: Are there differences in insulation material between these parts?

A: Yes. The SS-109-S-2 uses polybutylene terephthalate (PBT) with glass fill, while the HSS-109-S-2 uses liquid crystal polymer (LCP). Both materials are suitable for the specified operating temperature range and environmental conditions.

Q: Do both parts have the same contact material?

A: The SS-109-S-2 uses beryllium copper contacts. The HSS-109-S-2 uses beryllium copper and brass contacts. Both configurations maintain equivalent electrical performance for the specified application.

Q: Are both parts RoHS compliant?

A: Yes, both SS-109-S-2 and HSS-109-S-2 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can these connectors be used interchangeably in existing designs?

A: Yes, both parts are mechanically and electrically equivalent for board-to-board applications with 0.100" pitch and 9-position single-row configuration. Existing PCB layouts and mating connectors designed for either part will accommodate the substitute without modification.
