Amphenol ICC 76308-102LF Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76308-102LF is a 2-position receptacle connector featuring 0.100" (2.54mm) pitch through-hole mounting with gold-plated mating contacts. This BergCon® series connector is designed for board-to-board or cable applications and maintains Active product status with full inventory availability. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part becomes unavailable or when design requirements permit alternative contact geometries or insulation materials.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76308-102LF is determined by the following critical parameters:

• Connector Type & Contact Type: Receptacle with female socket contacts
• Position Count & Pitch: 2 positions at 0.100" (2.54mm) mating pitch
• Mounting & Termination: Through-hole solder termination
• Fastening Mechanism: Push-pull fastening
• Contact Finish: Gold-plated mating surface
• Flammability Compliance: UL94 V-0 rating
• RoHS Compliance: RoHS-compliant materials

The identified substitute part ESS-102-G-03 (Samtec Inc.) satisfies all mandatory substitution criteria. While secondary parameters such as insulation material (Liquid Crystal Polymer vs. Thermoplastic Polyester), contact shape (Circular vs. Square), and contact material (Beryllium Copper vs. Brass) differ, these variations do not preclude functional equivalence when the primary electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

Both the 76308-102LF and ESS-102-G-03 maintain Active product status and comply with RoHS requirements. The 76308-102LF carries RoHS Compliant certification, while the ESS-102-G-03 meets ROHS3 Compliant standards. Both connectors are rated UL94 V-0 for material flammability.

Selection between these parts should be based on:

• Mechanical Fit: The 76308-102LF features 0.335" insulation height and 0.135" contact post length, while the ESS-102-G-03 provides 0.300" insulation height and 0.123" contact post length. PCB layout and mating component clearances must accommodate these dimensional differences.

• Contact Finish Thickness: The 76308-102LF provides 30.0µin gold plating on mating contacts, compared to 10.0µin on the ESS-102-G-03. Applications requiring enhanced wear resistance or corrosion protection may favor the thicker gold finish.

• Insulation Material: The 76308-102LF uses glass-filled thermoplastic polyester, while the ESS-102-G-03 employs Liquid Crystal Polymer. LCP offers superior dimensional stability and lower moisture absorption.

• Compliance Certifications: Both parts satisfy RoHS and UL94 V-0 requirements. The ESS-102-G-03 provides documented operating temperature range (-55°C ~ 125°C), while the 76308-102LF does not specify this parameter.

Frequently Asked Questions (FAQ)

Q: Can the ESS-102-G-03 directly replace the 76308-102LF in existing designs?

A: Direct replacement requires verification of mechanical fit. The ESS-102-G-03 has a lower insulation height (0.300" vs. 0.335") and shorter contact post length (0.123" vs. 0.135"). PCB layout, mating component positioning, and clearance requirements must be evaluated to confirm compatibility.

Q: What is the significance of the contact finish thickness difference?

A: The 76308-102LF provides 30.0µin gold plating on mating contacts, while the ESS-102-G-03 provides 10.0µin. Thicker plating generally offers extended contact life in high-cycle mating applications and improved corrosion resistance in harsh environments. Application duty cycle and environmental exposure should guide this selection.

Q: Are both connectors suitable for the same temperature range?

A: The ESS-102-G-03 specifies an operating temperature range of -55°C ~ 125°C. The 76308-102LF does not provide a documented operating temperature specification in the available parameters. Applications requiring confirmed temperature performance should reference the ESS-102-G-03 datasheet or contact the manufacturer for 76308-102LF temperature ratings.

Q: What are the differences in insulation material, and does this affect performance?

A: The 76308-102LF uses glass-filled thermoplastic polyester, while the ESS-102-G-03 uses Liquid Crystal Polymer (LCP). LCP provides superior dimensional stability, lower moisture absorption, and better chemical resistance. For applications in high-humidity or chemically aggressive environments, the LCP insulation may offer performance advantages.

Q: Do both connectors meet the same compliance standards?

A: Both connectors are UL94 V-0 rated and RoHS compliant. The 76308-102LF is RoHS Compliant, while the ESS-102-G-03 is ROHS3 Compliant. Both are REACH Affected and carry EAR99 ECCN classification. Moisture Sensitivity Level differs: the 76308-102LF is MSL 1 (Unlimited), while the ESS-102-G-03 is Not Applicable.

Q: What is the difference between a standard receptacle and an elevated socket?

A: The 76308-102LF is classified as a standard receptacle, while the ESS-102-G-03 is an elevated socket. Elevated sockets feature raised contact positions, which can improve mating alignment and reduce insertion force in certain applications. PCB layout and mating component design must accommodate this geometric difference.
