Amphenol ICC 76383-302 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76383-302 is a through-hole, right-angle rectangular connector header with 4 positions at 0.100" (2.54mm) pitch, designed for board-to-cable/wire applications. The part features shrouded 2-wall construction with male pin contacts and friction lock fastening. Currently listed as obsolete product status, alternative equivalent parts are available to maintain design compatibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 76383-302 is determined by the following critical parameters:

• Connector type (Header vs. Receptacle)
• Contact type (Male Pin vs. Female Socket)
• Number of positions and row configuration
• Mating pitch (0.100" / 2.54mm)
• Mounting style (Through Hole, Right Angle)
• Shrouding configuration (Shrouded - 2 Wall)
• Termination method (Solder)
• Operating temperature range (-40°C ~ 125°C)
• Material flammability rating (UL94 V-0)

The primary substitute is 76383-302LF, which maintains identical mechanical and electrical specifications while offering active product status and RoHS compliance. The part 87606-308LF is listed as a substitute but represents a different connector type (receptacle vs. header) and position count (16 vs. 4), making it suitable only for applications requiring female socket receptacles with expanded position capacity.

Parameter Comparison

Engineering Selection Recommendations

For direct replacement of the obsolete 76383-302, the 76383-302LF is the primary equivalent. This part maintains identical mechanical and electrical specifications while offering active product status, ensuring continued availability and supply chain support. The 76383-302LF achieves RoHS compliance and carries REACH Affected status, meeting current regulatory requirements for new designs and production runs.

The 87606-308LF is not a direct substitute due to fundamental differences in connector architecture: it is a receptacle (female socket) rather than a header (male pin), accommodates 16 positions instead of 4, and features straight-through mounting rather than right-angle configuration. Selection of 87606-308LF requires complete redesign of mating connector interfaces and PCB layout.

For applications requiring the exact form factor and pin configuration of the original 76383-302, the 76383-302LF provides full functional and mechanical compatibility with improved compliance status.

Frequently Asked Questions (FAQ)

Q: Can 76383-302LF be used as a direct replacement for 76383-302?

A: Yes. The 76383-302LF maintains identical specifications for connector type, contact type, position count, pitch, mounting style, shrouding, termination method, current rating, and operating temperature range. The primary differences are product status (active vs. obsolete) and RoHS compliance (compliant vs. non-compliant). Packaging differs (bulk vs. unspecified), and contact finish on the post uses tin instead of tin-lead.

Q: What is the difference between 76383-302LF and 87606-308LF?

A: These are fundamentally different connector types. The 76383-302LF is a 4-position header with male pins and right-angle mounting. The 87606-308LF is a 16-position receptacle with female sockets and straight-through mounting. They are not interchangeable without complete circuit redesign.

Q: Why is the original 76383-302 listed as obsolete?

A: The 76383-302 is obsolete due to its RoHS non-compliant status and tin-lead contact finish. The 76383-302LF represents the active production equivalent with RoHS compliance and improved environmental specifications.

Q: Are there any electrical performance differences between 76383-302 and 76383-302LF?

A: No. Both parts share identical current rating (3A), operating temperature range (-40°C ~ 125°C), contact material (phosphor bronze), and mating contact finish (gold, GXT™). The contact finish thickness on the post differs (150.0µin vs. 78.7µin), but both meet the same electrical performance requirements.

Q: What packaging options are available?

A: The 76383-302LF is supplied in bulk packaging. The 87606-308LF is supplied in tube packaging. Packaging selection depends on production volume and handling requirements.
