SS-109-S-2-N Equivalent & Substitute Parts

Part Overview

The SS-109-S-2-N 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, contact configuration, and material compliance standards.

Key Parameters

Substitute Part Grouping Explanation

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

• 9-position receptacle configuration
• 0.100" (2.54mm) mating pitch
• Female socket contact type
• Through-hole solder termination
• Gold-plated mating contacts (10.0µin thickness)
• Single-row board-to-board style
• Operating temperature range of -55°C to 125°C
• ROHS3 compliance
• MSL 1 rating

The primary difference between these parts is the insulation material: SS-109-S-2-N uses Polybutylene Terephthalate (PBT) Glass Filled, while HSS-109-S-2 uses Liquid Crystal Polymer (LCP). Both materials are suitable for the specified operating temperature range and environmental conditions.

Parameter Comparison

Engineering Selection Recommendations

Both SS-109-S-2-N 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 should be based on insulation material requirements for the specific application. The SS-109-S-2-N uses PBT glass-filled insulation, while the HSS-109-S-2 uses LCP insulation. Both materials maintain performance within the specified -55°C to 125°C operating range and carry MSL 1 ratings, indicating no moisture sensitivity restrictions.

Frequently Asked Questions (FAQ)

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

A: Substitution is valid when the connector maintains identical pitch (0.100"), position count (9), contact type (female socket receptacle), mounting method (through-hole solder), contact finish (gold mating, tin post), 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. SS-109-S-2-N uses Polybutylene Terephthalate (PBT) glass-filled insulation, while HSS-109-S-2 uses Liquid Crystal Polymer (LCP) insulation. Both materials are rated for the same operating temperature range and environmental conditions specified for this connector category.

Q: Do both parts have the same compliance certifications?

A: Both SS-109-S-2-N and HSS-109-S-2 are ROHS3 compliant with MSL 1 ratings and identical ECCN and HTSUS classifications.

Q: What is the contact material composition for each part?

A: SS-109-S-2-N uses Beryllium Copper contacts. HSS-109-S-2 uses Beryllium Copper and Brass contacts. Both configurations provide equivalent electrical performance for the specified application.

Q: Are the physical dimensions identical between these connectors?

A: Yes. Both parts have identical insulation height (0.100"), contact length (0.125"), and mating pitch (0.100"), ensuring mechanical compatibility in board-to-board applications.
