Amphenol ICC 76383-323 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76383-323 is a through-hole, right-angle rectangular connector header with 46 positions at 2.54mm pitch, designed for board-to-cable/wire applications. This connector features shrouded 2-wall construction with male pin contacts and friction lock fastening. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

The Amphenol ICC 76383-323LF qualifies as a direct substitute based on the following critical parameters:

• Identical connector type, contact type, and position count (46 positions, 2 rows)
• Matching pitch specifications (0.100" mating pitch, 0.100" row spacing)
• Identical mounting configuration (through hole, right angle)
• Matching shrouding design (shrouded 2-wall)
• Identical termination method (solder)
• Same contact material (phosphor bronze) and mating contact finish (gold)
• Identical insulation material and flammability rating (UL94 V-0)
• Same series designation (Dubox™)

The primary distinction is product status: 76383-323 is obsolete, while 76383-323LF is active production. The "LF" suffix indicates lead-free compliance, reflecting the transition to RoHS-compliant manufacturing.

Parameter Comparison

Engineering Selection Recommendations

The 76383-323LF is the appropriate selection for new designs and ongoing procurement. This part maintains full mechanical and electrical compatibility with the obsolete 76383-323 while offering the following advantages:

• Active production status ensures long-term availability and supply chain stability
• RoHS compliance aligns with current regulatory requirements and industry standards
• Documented operating temperature range (-40°C ~ 125°C) and current rating (3A) provide explicit performance specifications
• Lead-free contact finish (tin) on posts meets environmental compliance requirements while maintaining gold mating surface for reliable electrical contact

For legacy systems currently using 76383-323, direct substitution with 76383-323LF is supported without design modification.

Frequently Asked Questions (FAQ)

Q: Can 76383-323LF be used as a direct replacement for 76383-323?

A: Yes. Both parts share identical mechanical dimensions, pitch specifications, contact configuration, and mounting characteristics. The primary difference is product status and RoHS compliance. The 76383-323LF is the active production equivalent.

Q: What does the "LF" suffix indicate?

A: The "LF" designation indicates lead-free manufacturing, reflecting compliance with RoHS directives. The contact finish on the post is tin rather than tin-lead, while the mating surface remains gold-plated.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. Both connectors feature identical 46-position, 2-row configuration with 2.54mm pitch, shrouded 2-wall design, and solder termination. PCB footprints and mating connector requirements remain unchanged.

Q: What is the packaging difference?

A: The 76383-323LF is supplied in tube packaging, which is standard for active production parts. Original packaging specifications for 76383-323 are not documented in available data.

Q: Are the electrical performance specifications identical?

A: The 76383-323LF provides documented specifications: 3A current rating and -40°C ~ 125°C operating temperature range. The original 76383-323 does not have these specifications documented. The gold mating contact finish and phosphor bronze material ensure equivalent electrical performance in both parts.
