Amphenol ICC 76385-304 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76385-304 is a shrouded rectangular connector header designed for through-hole mounting in board-to-cable/wire applications. This 8-position, 2-row connector operates at 0.100" (2.54mm) pitch and features solder termination with friction lock fastening. The part is classified as obsolete, making identification of suitable substitutes necessary for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

The 76385-304LF serves as a direct substitute for the 76385-304 based on matching electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Connector type, contact type, and gender remain identical (Header, Male Pin)
• Position count and row configuration are preserved (8 positions, 2 rows)
• Mating pitch and row spacing are identical (0.100" / 2.54mm)
• Mounting method and termination type are unchanged (Through Hole, Solder)
• Shrouding configuration and fastening mechanism are the same (Shrouded - 2 Wall, Friction Lock)
• Contact geometry and insulation material specifications match (Square contacts, Thermoplastic Glass Filled)
• Flammability rating remains compliant (UL94 V-0)

The 76385-304LF differs from the main part in product status (Active vs. Obsolete), RoHS compliance status, contact finish specifications, and operating temperature range, but these differences do not affect mechanical or electrical interchangeability in applications where the core connector function is required.

Parameter Comparison

Engineering Selection Recommendations

The 76385-304LF is the direct active substitute for the obsolete 76385-304. Selection of the 76385-304LF is appropriate for new designs and component replenishment due to its active product status and RoHS compliance. Both parts maintain identical mechanical and electrical interface specifications, ensuring pin-for-pin compatibility in applications requiring 8-position, 2-row, 0.100" pitch shrouded headers with through-hole solder termination.

The transition from the 76385-304 to 76385-304LF involves a change in post contact finish from Tin-Lead to Tin, reflecting modern lead-free manufacturing standards. The 76385-304LF also incorporates GXT™ mating contact finish technology, representing an enhancement to the original specification while maintaining the same 30.0µin (0.76µm) thickness requirement.

Frequently Asked Questions (FAQ)

Q: Can the 76385-304LF be used as a direct replacement for the 76385-304 in existing applications?

A: Yes. The 76385-304LF maintains identical mechanical and electrical interface specifications. Pin count, pitch, row spacing, mounting type, and termination method are unchanged. Physical dimensions and contact geometry are preserved, ensuring compatibility in existing PCB layouts and mating connector designs.

Q: What is the significance of the "LF" designation in the 76385-304LF part number?

A: The "LF" suffix indicates lead-free compliance. The 76385-304LF uses Tin post contact finish instead of Tin-Lead, aligning with RoHS regulations and modern manufacturing standards.

Q: Are there differences in current or voltage ratings between these parts?

A: Current and voltage ratings are not specified in the technical data for either part. Substitution decisions should be based on the mechanical and electrical interface parameters provided, not on ratings that are not documented.

Q: What is the difference between the contact finishes on the mating surfaces?

A: The 76385-304 uses standard Gold finish, while the 76385-304LF uses Gold with GXT™ technology. Both maintain the same 30.0µin (0.76µm) thickness specification. GXT™ represents an enhancement in contact finish durability and performance.

Q: Does the change in insulation color affect compatibility?

A: No. The 76385-304 features Blue insulation, while the 76385-304LF features Black insulation. Insulation color is a visual identifier only and does not affect electrical or mechanical compatibility.

Q: What is the operating temperature range for these connectors?

A: The 76385-304LF operates from -40°C to 125°C. Operating temperature is not specified for the 76385-304.

Q: Are both parts moisture sensitive?

A: No. Both parts carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.
