Amphenol ICC 76384-404 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76384-404 is a vertical rectangular connector header designed for through-hole mounting applications. This component features a 4-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 essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

The 76384-404LF serves as a direct substitute for the 76384-404 based on matching electrical and mechanical parameters. Substitution is valid where the following criteria are met:

• Identical connector type (Header), contact type (Male Pin), and position count (4)
• Matching pitch specification (0.100" / 2.54mm)
• Identical mounting method (Through Hole) and termination type (Solder)
• Matching shrouding configuration (Shrouded - 2 Wall)
• Equivalent insulation material (Thermoplastic, Glass Filled) and flammability rating (UL94 V-0)
• Identical contact geometry (Square shape, matching mating and post lengths)

The primary distinction between these parts relates to product status, contact finish specifications, and regulatory compliance rather than functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 76384-404LF is the active production equivalent for the obsolete 76384-404. Selection of the 76384-404LF is appropriate where:

• RoHS compliance is required for new designs or production runs
• REACH compliance documentation is necessary for supply chain requirements
• Active product status and ongoing manufacturer support are required
• Operating temperature range (-40°C ~ 125°C) and current rating (3A) specifications meet application requirements

The transition from Tin-Lead to Tin contact finish in the 76384-404LF reflects modern manufacturing standards and regulatory alignment. Both parts maintain identical mechanical and electrical interface specifications, ensuring direct substitution in existing PCB designs without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the 76384-404LF directly replace the 76384-404 in existing designs?

A: Yes. Both parts share identical connector type, position count, pitch spacing, mounting method, shrouding configuration, and contact geometry. PCB footprints and mating interface specifications are equivalent.

Q: What is the primary reason for substitution?

A: The 76384-404 is classified as obsolete. The 76384-404LF is the active production part from the same manufacturer and series, providing design continuity and supply chain availability.

Q: Are there compliance differences between these parts?

A: Yes. The 76384-404LF is RoHS Compliant and REACH Affected, while the 76384-404 is RoHS non-compliant and REACH Unaffected. For applications requiring regulatory compliance, the 76384-404LF is the appropriate selection.

Q: What changed in the contact finish specification?

A: The 76384-404 uses Tin-Lead finish (150.0µin / 3.81µm), while the 76384-404LF uses Tin finish (78.7µin / 2.00µm). Both finishes provide equivalent electrical and mechanical performance for solder termination applications.

Q: Does the insulation color difference affect functionality?

A: No. The color change from Blue to Black is a cosmetic specification change. Insulation material, flammability rating, and electrical properties remain identical.

Q: What operating conditions are specified for the 76384-404LF?

A: Operating temperature range is -40°C to 125°C with a current rating of 3A per contact. The original 76384-404 does not specify these parameters in available documentation.

Q: Are packaging options different between these parts?

A: The 76384-404 packaging is not specified. The 76384-404LF is supplied in Bulk packaging. Confirm packaging requirements with your procurement specifications.
