Amphenol ICC 76384-308 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76384-308 is a shrouded vertical rectangular connector header designed for through-hole mounting in board-to-cable/wire applications. This 8-position connector operates at 0.100" (2.54mm) pitch and features male pin contacts with gold-plated mating surfaces and tin-lead post finishes. The part is classified as obsolete, making identification of suitable substitutes essential for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76384-308 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Header with male pin contacts
• Electrical Interface: 8 positions at 0.100" (2.54mm) pitch
• Mechanical Form Factor: Shrouded 2-wall design, through-hole mounting
• Termination Method: Solder termination with square contact geometry
• Material & Safety Compliance: Thermoplastic glass-filled insulation, UL94 V-0 rating

The substitute part 76384-308LF maintains identical mechanical and electrical specifications while offering improved compliance status and enhanced contact finishes.

Parameter Comparison

Engineering Selection Recommendations

The 76384-308LF is the direct active substitute for the obsolete 76384-308. Both parts share identical mechanical and electrical interface specifications, ensuring direct compatibility in existing designs.

Compliance Advantages of 76384-308LF:

• Active product status with ongoing manufacturer support
• RoHS compliant formulation (versus non-compliant original)
• Enhanced contact finish with GXT™ technology on mating surfaces
• Tin post finish (lead-free) replacing tin-lead composition
• Specified operating temperature range (-40°C ~ 125°C) and current rating (3A)

Design Considerations: The substitution is mechanically and electrically transparent. The 76384-308LF maintains all critical dimensional and contact specifications. The shift from tin-lead to tin post finish aligns with modern manufacturing standards. Insulation color change from blue to black does not affect functional performance.

Frequently Asked Questions (FAQ)

Q: Are the 76384-308 and 76384-308LF mechanically interchangeable?

A: Yes. Both parts maintain identical pitch (0.100" / 2.54mm), contact geometry (square male pins), shrouding configuration (2-wall), and overall dimensions. PCB footprints and mating connector interfaces are identical.

Q: What is the significance of the "LF" suffix in 76384-308LF?

A: The "LF" designation indicates lead-free composition, reflecting RoHS compliance and the use of tin-based post finishes instead of tin-lead alloys.

Q: Can I use 76384-308LF as a direct replacement in designs originally specified for 76384-308?

A: Yes. The electrical and mechanical specifications are equivalent. The 76384-308LF provides improved compliance status and is the recommended active alternative for new procurement and design updates.

Q: What is the difference in contact finish between these parts?

A: The 76384-308 uses gold mating finish with tin-lead posts. The 76384-308LF uses gold mating finish with GXT™ enhancement and tin posts (lead-free). Both maintain 30.0µin (0.76µm) mating finish thickness.

Q: Are there packaging differences between these parts?

A: The 76384-308LF is supplied in tube packaging. The original 76384-308 packaging specification is not provided in the technical data.

Q: What is the current rating for these connectors?

A: The 76384-308LF is rated for 3A per contact. The original 76384-308 current rating is not specified in available documentation.
