Amphenol ICC 76384-406 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76384-406 is a vertical rectangular connector header designed for through-hole mounting applications. This component features a 6-position, single-row configuration with 0.100" (2.54mm) pitch spacing and shrouded 2-wall design for board-to-cable/wire connections. 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 76384-406LF serves as a direct substitute for the 76384-406 based on the following critical parameters that determine functional compatibility:

• Connector Type & Contact Configuration: Both parts are header connectors with male pins
• Position Count & Pitch: Identical 6-position, single-row layout with 0.100" (2.54mm) mating pitch
• Mounting & Termination: Both use through-hole mounting with solder termination
• Mechanical Dimensions: Contact lengths, insulation height, and overall geometry are identical
• Shrouding Design: Both feature shrouded 2-wall construction
• Material & Flammability: Both use thermoplastic glass-filled insulation with UL94 V-0 rating
• Series Compatibility: Both belong to the Dubox™ series

The primary differences between these parts relate to product status, RoHS compliance, contact finish specifications, and operating temperature range—factors that do not affect mechanical or electrical interchangeability in standard applications.

Engineering Selection Recommendations

The 76384-406LF is the direct substitute for the obsolete 76384-406. Selection of the substitute part is based on the following engineering considerations:

Product Status: The 76384-406 is classified as obsolete, while the 76384-406LF is active. For new designs and ongoing procurement, the 76384-406LF provides assured supply and manufacturer support.

Compliance & Certifications: The 76384-406LF is RoHS compliant, whereas the original part is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulations. Both parts maintain UL94 V-0 flammability certification and identical MSL ratings.

Contact Finish Specification: The 76384-406LF uses pure tin plating (78.7µin / 2.00µm thickness) on both mating and post contacts, replacing the tin-lead finish of the original part. This change aligns with lead-free manufacturing standards and does not affect mechanical or electrical interchangeability.

Mechanical & Electrical Compatibility: All critical dimensions, contact configurations, pitch spacing, and mounting characteristics are identical between the two parts, ensuring direct substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 76384-406LF be used as a direct replacement for the 76384-406 in existing designs?

A: Yes. The 76384-406LF is mechanically and electrically identical to the 76384-406. All contact dimensions, pitch spacing, mounting type, and connector geometry are the same. The substitute part can be used without PCB redesign or connector interface modification.

Q: What is the significance of the "LF" designation in the part number 76384-406LF?

A: The "LF" suffix indicates lead-free construction. This designation reflects the contact finish specification (pure tin instead of tin-lead) and RoHS compliance status of the part.

Q: Are there any compatibility concerns with the change from tin-lead to tin plating?

A: No compatibility concerns exist for standard solder joint applications. Both finishes are compatible with standard PCB soldering processes. The tin finish on the 76384-406LF meets lead-free manufacturing requirements.

Q: What is the difference in packaging between these parts?

A: The 76384-406 packaging specification is not provided in the technical data. The 76384-406LF is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Does the 76384-406LF have specified electrical ratings?

A: Yes. The 76384-406LF is rated for 3A current and operates across the temperature range of -40°C to 125°C. The original 76384-406 does not have published electrical ratings in the available technical documentation.

Q: Are both parts moisture sensitive?

A: No. Both the 76384-406 and 76384-406LF carry MSL rating 1 (Unlimited), indicating no moisture sensitivity and no special storage or handling requirements.
