ESS-118-G-23 Equivalent & Substitute Parts

Part Overview

The ESS-118-G-23 is an 18-position elevated socket 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 beryllium copper contacts and is constructed from liquid crystal polymer (LCP) insulation material rated UL94 V-0. The part is currently active in production with 925 units in stock. Substitute parts are identified when all critical electrical and mechanical parameters remain identical, ensuring direct interchangeability without design modification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ESS-118-G-23 is determined by strict equivalence across the following critical parameters:

• Connector type (Elevated Socket)
• Contact type (Female Socket)
• Number of positions (18)
• Pitch specification (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Contact finish and thickness (Gold, 10.0µin)
• Insulation material (LCP)
• Insulation height (0.300")
• Operating temperature range (-55°C ~ 125°C)
• Flammability rating (UL94 V-0)
• RoHS compliance (ROHS3)

The ESS-118-G-23 has one identified substitute: ESS-118-G-03. Both parts share identical electrical and mechanical specifications, differing only in packaging designation. This substitution is valid for direct component replacement in existing designs.

Parameter Comparison

Engineering Selection Recommendations

Both ESS-118-G-23 and ESS-118-G-03 are active production parts from Samtec Inc. with full ROHS3 compliance and UL94 V-0 flammability certification.
