Key Parameters

Substitute Part Grouping Explanation

The SS-115-G-29 qualifies as a direct substitute for the SS-115-G-18 based on the following critical parameters that determine functional interchangeability:

• Connector Type & Contact Configuration: Both are receptacle connectors with female socket contacts
• Position Count & Pitch: Both feature 15 positions at 0.100" (2.54mm) mating pitch
• Mounting & Termination: Both use through-hole mounting with solder termination
• Contact Materials & Finish: Both employ beryllium copper contacts with identical gold plating specifications (30.0µin mating, 10.0µin post)
• Insulation Specifications: Both use black PBT glass-filled insulation with 0.100" height
• Operating Environment: Both rated for -55°C ~ 125°C operating temperature range
• Compliance & Standards: Both are ROHS3 compliant with MSL 1 rating
• Series & Base Product: Both belong to the SS series with identical base product number SS-115

Parameter Comparison

Engineering Selection Recommendations

Both the SS-115-G-18 and SS-115-G-29 are Active product status components manufactured by Samtec Inc. and maintain identical ROHS3 compliance and MSL 1 ratings. Selection between these parts is based on inventory availability and procurement lead times, as all specified electrical and mechanical parameters are equivalent. Both parts are suitable for direct substitution in board-to-board connector applications requiring 15-position, 0.100" pitch receptacle configurations with gold-plated contacts and through-hole solder termination.

Frequently Asked Questions (FAQ)

Q: Can SS-115-G-29 be used as a direct replacement for SS-115-G-18?
