Amphenol ICC 76383-313 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76383-313 is a through-hole, right-angle rectangular connector header with 26 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 necessary for ongoing procurement and new design implementations.

Substitute Part Grouping Explanation

Substitution for the 76383-313 is determined by the following critical parameters: connector type (header), contact type (male pin), number of positions (26), number of rows (2), mating pitch (0.100"/2.54mm), row spacing (0.100"/2.54mm), mounting type (through hole, right angle), shrouding configuration (shrouded 2-wall), termination method (solder), and current rating (3A).

The primary direct substitute is the 76383-313LF, which maintains identical electrical and mechanical specifications while differing only in RoHS compliance status and contact finish thickness on the post. The 87606-317LF is listed as an alternative but represents a different connector class (receptacle vs. header, 34 positions vs. 26 positions) and is not a direct functional equivalent for applications requiring the original 26-position header configuration.

Engineering Selection Recommendations

The 76383-313LF is the direct functional equivalent for the obsolete 76383-313. Both parts maintain identical electrical and mechanical specifications across all critical parameters: 26-position header configuration, 0.100" (2.54mm) pitch, through-hole right-angle mounting, shrouded 2-wall construction, and 3A current rating. The primary distinction is product status: the 76383-313LF is active and available, while the original part is obsolete.

The 76383-313LF offers improved compliance status with RoHS compliance and lead-free post finish (tin vs. tin-lead), making it suitable for applications subject to environmental regulations. Both parts carry UL94 V-0 flammability rating and operate across the same temperature range (-40°C ~ 125°C).

The 87606-317LF is not a direct substitute due to fundamental differences in connector class (receptacle vs. header), position count (34 vs. 26), and mounting orientation (straight vs. right angle). This part is suitable only for applications requiring a 34-position receptacle connector with board-to-board configuration.

Frequently Asked Questions (FAQ)

Q: Can the 76383-313LF directly replace the 76383-313 in existing designs?

A: Yes. The 76383-313LF maintains identical electrical and mechanical specifications for all critical parameters including position count, pitch, mounting type, and current rating. The primary difference is product status (active vs. obsolete) and RoHS compliance.

Q: What is the difference between the tin-lead and tin post finishes?

A: The original 76383-313 uses tin-lead post finish (150.0µin/3.81µm thickness), while the 76383-313LF uses tin post finish (78.7µin/2.00µm thickness). Both finishes provide solder compatibility. The lead-free tin finish in the 76383-313LF aligns with RoHS requirements.

Q: Is the 87606-317LF compatible with applications designed for the 76383-313?

A: No. The 87606-317LF is a receptacle connector with 34 positions and board-to-board configuration, fundamentally different from the 26-position header design of the 76383-313. Position count and connector type mismatch prevent direct substitution.

Q: What packaging is available for the substitute parts?

A: The 76383-313LF is supplied in tube packaging. The 87606-317LF is also supplied in tube packaging. Verify packaging requirements for your procurement process.

Q: Are there any compliance considerations when switching from 76383-313 to 76383-313LF?

A: The 76383-313LF is RoHS compliant with lead-free post finish, while the original 76383-313 is RoHS non-compliant with tin-lead finish. Both parts are REACH unaffected and carry identical UL94 V-0 flammability ratings. Applications subject to RoHS requirements benefit from the 76383-313LF specification.
