Amphenol ICC 76383-318 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76383-318 is a shrouded rectangular connector header designed for through-hole, right-angle board-to-cable/wire applications. This 36-position, 2-row connector operates at 0.100" (2.54mm) pitch and features gold-plated mating contacts with tin-lead post finish. The part is classified as obsolete, making identification of active equivalent components essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

The 76383-318LF serves as a direct substitute for the 76383-318 based on the following critical parameters:

• Identical connector type, contact configuration, and pitch (0.100" / 2.54mm)
• Matching number of positions (36) and row arrangement (2 rows)
• Identical mounting method (through hole, right angle) and shrouding design (shrouded - 2 wall)
• Same contact material (phosphor bronze) and insulation composition (polyester, glass filled)
• Equivalent mating contact dimensions and geometry
• Identical base product number (76383), confirming mechanical and electrical compatibility

The primary distinction is product status: 76383-318LF is active and RoHS compliant, whereas 76383-318 is obsolete and RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

The 76383-318LF is the direct active equivalent for the obsolete 76383-318. Selection of the substitute part is based on:

• Identical mechanical and electrical specifications across all critical parameters
• Active product status ensuring long-term availability and supply chain continuity
• RoHS compliance of the substitute part, meeting current regulatory requirements
• Equivalent UL94 V-0 flammability rating and moisture sensitivity classification
• Matching ECCN and HTSUS classifications for export and tariff purposes

The primary difference in contact post finish (tin-lead versus tin) reflects modern lead-free manufacturing standards in the 76383-318LF. This change does not affect functional compatibility in applications where the original part was specified.

Frequently Asked Questions (FAQ)

Q: Are the 76383-318 and 76383-318LF mechanically interchangeable?

A: Yes. Both parts share identical connector geometry, pitch, mounting method, and contact dimensions. They are direct mechanical substitutes.

Q: What is the significance of the "LF" designation in 76383-318LF?

A: The "LF" suffix indicates lead-free manufacturing, reflecting RoHS compliance. The 76383-318LF uses tin post finish instead of tin-lead, consistent with lead-free soldering standards.

Q: Can the 76383-318LF be used in applications originally designed for the 76383-318?

A: Yes. The parts are functionally equivalent. The 76383-318LF is the recommended replacement for new designs and ongoing production support.

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

A: The 76383-318 packaging is not specified in available documentation. The 76383-318LF is supplied in tube packaging.

Q: Are there any temperature or current rating differences?

A: The 76383-318LF specifies an operating temperature range of -40°C to 125°C and a current rating of 3A per contact. The original 76383-318 does not provide these specifications in available documentation.

Q: Why is the 76383-318 classified as obsolete?

A: Obsolescence reflects the manufacturer's transition to active, RoHS-compliant alternatives. The 76383-318LF represents the current production equivalent.

Q: Are both parts suitable for high-reliability applications?

A: Both parts meet UL94 V-0 flammability requirements and carry MSL 1 (unlimited) moisture sensitivity ratings. Selection should be based on current product availability and regulatory compliance requirements for the application.
