Key Parameters

Substitute Part Grouping Explanation

The ESS-125-G-23 has one identified substitute: ESS-125-G-03. Substitution eligibility is determined by the following critical parameters that must remain identical:

• Number of positions: 25
• Pitch - mating: 0.100" (2.54mm)
• Connector type: Elevated Socket
• Contact type: Female Socket
• Mounting type: Through Hole
• Termination method: Solder
• Contact finish (mating and post): Gold
• Insulation material: Liquid Crystal Polymer (LCP)
• Operating temperature range: -55°C ~ 125°C
• Material flammability rating: UL94 V-0
• RoHS compliance: ROHS3 Compliant

Both parts share the same base product number (ESS-125) and series designation, confirming functional equivalence for board-to-board socket applications.

Parameter Comparison

Engineering Selection Recommendations

Both ESS-125-G-23 and ESS-125-G-03 are active products from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts is based on inventory availability and supply chain requirements rather than functional differences. Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial and commercial applications. The ESS-125-G-03 variant is suitable for direct substitution in any application currently specified for the ESS-125-G-23.

Frequently Asked Questions (FAQ)

Q: Can ESS-125-G-03 be used as a direct replacement for ESS-125-G-23?

A: Yes. Both parts share identical electrical and mechanical parameters, including connector type, position count, pitch, contact finish, insulation material, and operating temperature range. They are functionally equivalent for board-to-board socket applications.

Q: What determines substitution eligibility for this connector family?

A: Substitution is valid when the following parameters remain constant: 25-position count, 0.100" (2.54mm) pitch, elevated socket connector type, female socket contacts, through-hole mounting, solder termination, gold contact finish, LCP insulation, -55°C to 125°C operating range, and UL94 V-0 flammability rating.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant and carry UL94 V-0 material flammability certification. Regulatory and compliance status is identical.

Q: What is the difference between ESS-125-G-23 and ESS-125-G-03?

A: The parts are variants within the same ESS-125 base product family. The suffix designations (-G-23 and -G-03) indicate packaging or configuration variants, but all critical electrical and mechanical parameters are identical.

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

A: Yes. Both connectors have identical footprint requirements, mounting hole patterns, and solder pad configurations for through-hole PCB assembly. No design modifications are required when substituting between these parts.
