Amphenol ICC 76382-321 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76382-321 is a shrouded right-angle header connector with 21 positions at 2.54mm pitch, designed for through-hole board-to-cable/wire applications. This connector features male pins with gold-plated mating contacts and tin-lead post finishes, housed in a polyester glass-filled insulation body with UL94 V-0 flammability rating.

The 76382-321 carries an obsolete product status. Identifying functionally equivalent active alternatives ensures design continuity and supply chain reliability for new production runs and ongoing support of existing systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76382-321 is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (21)
• Number of rows (1)
• Mating pitch (0.100" / 2.54mm)
• Mounting configuration (Through Hole, Right Angle)
• Shrouding design (Shrouded - 4 Wall)
• Termination method (Solder)
• Contact finish on mating surface (Gold, GXT™)
• Insulation material (Polyester, Glass Filled)
• Flammability rating (UL94 V-0)
• Series designation (Dubox™)

The 76382-321LF qualifies as a direct substitute based on full alignment with these parameters. The primary distinction is product status: the 76382-321 is obsolete, while the 76382-321LF is active. Secondary differences in contact finish post composition and thickness, operating temperature specification, and RoHS compliance status do not affect mechanical or electrical interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

The 76382-321LF is the direct functional equivalent for the obsolete 76382-321. Selection between these parts should be based on the following criteria:

For new designs and active production: The 76382-321LF is the appropriate choice. It maintains full mechanical and electrical compatibility while offering active product status, RoHS compliance, and documented operating temperature and current ratings. The shift from tin-lead to tin post finish aligns with modern manufacturing standards and environmental regulations.

For legacy system support: The 76382-321 remains available in current inventory (849 units). Use of the original part number is justified only when design documentation explicitly specifies tin-lead post finish or when RoHS non-compliance is a system requirement. In all other cases, transition to the 76382-321LF.

Compliance considerations: The 76382-321LF carries RoHS Compliant status and REACH Unaffected designation, making it suitable for applications subject to environmental and regulatory compliance requirements. The 76382-321 does not meet these standards.

Frequently Asked Questions (FAQ)

Q: Can the 76382-321LF be used as a direct replacement for the 76382-321 in existing assemblies?

A: Yes. Both connectors share identical mechanical dimensions, mating pitch, contact geometry, and electrical interface specifications. The 76382-321LF is mechanically and electrically interchangeable with the 76382-321 in all standard applications.

Q: What is the significance of the "LF" suffix in the part number 76382-321LF?

A: The "LF" designation indicates lead-free composition, specifically the use of tin rather than tin-lead in the post finish. This reflects compliance with RoHS directives and modern manufacturing practices.

Q: Are there differences in solderability between the 76382-321 and 76382-321LF?

A: Both parts are designed for solder termination. The 76382-321LF, with its lead-free post finish, is optimized for lead-free solder processes. The 76382-321, with tin-lead finish, is compatible with traditional lead-containing solder. Soldering parameters should align with the specific post finish composition.

Q: What is the packaging difference between these parts?

A: The 76382-321LF is supplied in tube packaging. The 76382-321 packaging specification is not provided in the technical data. Confirm packaging requirements with your procurement specification before ordering.

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

A: Both connectors meet UL94 V-0 flammability requirements and carry MSL 1 (Unlimited) moisture sensitivity ratings. The 76382-321LF provides documented operating temperature range (-40°C ~ 125°C) and current rating (3A), supporting design verification for high-reliability applications. Operating temperature and current specifications for the 76382-321 are not provided.

Q: Which part should be specified for new designs?

A: Specify the 76382-321LF for all new designs. It offers active product status, RoHS compliance, and complete electrical and thermal specifications. The 76382-321 is obsolete and should not be selected for new development.
