SS-103-S-22-N Equivalent & Substitute Parts

Part Overview

The SS-103-S-22-N is a 3-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 for reliable solder termination. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when inventory requirements necessitate alternative stock sources.

Key Parameters

Substitute Part Grouping Explanation

The SS-103-S-2 is classified as a direct substitute for the SS-103-S-22-N based on the following critical parameters that determine functional equivalence:

• Identical connector type (Receptacle) and contact type (Female Socket)
• Matching position count (3 positions)
• Identical mating pitch (0.100" / 2.54mm)
• Same mounting method (Through Hole) and termination type (Solder)
• Identical contact finish specification (Gold mating surface)
• Matching operating temperature range (-55°C ~ 125°C)
• Same insulation material (PBT, Glass Filled)
• Both parts share the same base product number (SS-103)
• Both manufactured by Samtec Inc.

Parameter Comparison

Engineering Selection Recommendations

Both SS-103-S-22-N and SS-103-S-2 are active production parts with ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability and lead time requirements. The SS-103-S-2 currently maintains higher inventory levels (3154 pcs vs. 1155 pcs), which may provide supply chain advantages. Both parts are suitable for applications requiring 3-position, 0.100" pitch board-to-board receptacle connectors with gold-plated contacts and solder termination across the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Are SS-103-S-22-N and SS-103-S-2 electrically and mechanically interchangeable?

A: Yes. Both connectors share identical specifications for contact type, position count, mating pitch, mounting method, termination type, contact finish, and operating temperature range. They are direct functional equivalents.

Q: What is the significance of the different part number suffixes?

A: Both parts share the base product number SS-103 and belong to the same connector series. The suffix variations reflect different packaging or distribution configurations, but the core connector specifications remain identical.

Q: Are both parts RoHS compliant?

A: Yes. Both SS-103-S-22-N and SS-103-S-2 are ROHS3 compliant.

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

A: Both connectors are rated for operating temperatures from -55°C to 125°C, making them suitable for standard industrial and commercial temperature ranges.

Q: What is the contact material composition?

A: Both connectors use beryllium copper contacts with gold plating on the mating surface (10.0µin / 0.25µm thickness) and tin plating on the post surface for solder termination.
