Amphenol ICC 76385-313 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76385-313 is a shrouded rectangular connector header designed for through-hole mounting in board-to-cable/wire applications. This component features 26 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing and is part of the Dubox™ series. The main part number 76385-313 carries an obsolete product status, making identification of suitable substitutes necessary for ongoing design requirements and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 76385-313LF is classified as a direct manufacturer equivalent based on the following critical parameters that determine substitutability:

• Identical connector type, contact type, and position count (26 positions, 2 rows)
• Matching pitch specifications (0.100" mating pitch and row spacing)
• Identical mounting method (through hole) and shrouding configuration (shrouded - 2 wall)
• Same termination method (solder) and contact shape (square)
• Identical insulation material composition and flammability rating (UL94 V-0)
• Same base product number (76385) within the Dubox™ series

The primary distinction between these parts is the product status transition from obsolete to active, along with corresponding compliance and packaging updates.

Parameter Comparison

Engineering Selection Recommendations

The 76385-313LF serves as the active production equivalent to the obsolete 76385-313. Selection between these parts depends on regulatory and compliance requirements:

For applications requiring RoHS compliance, the 76385-313LF is the appropriate selection. This part incorporates lead-free solder finish on the post contacts and carries RoHS compliant certification, whereas the original 76385-313 uses tin-lead finish and is RoHS non-compliant.

For applications with no RoHS requirement and where existing inventory of 76385-313 is available, the original part remains functionally equivalent in all mechanical and electrical parameters.

The 76385-313LF includes GXT™ enhanced gold plating on mating contacts, providing improved contact durability compared to standard gold finish. The post contact finish thickness is reduced in the substitute part (78.7µin versus 150.0µin), reflecting modern lead-free manufacturing standards.

Both parts maintain identical mechanical compatibility, pitch specifications, and mounting characteristics, ensuring direct substitution in board-level applications without design modification.

Frequently Asked Questions (FAQ)

Q: Can 76385-313LF be used as a direct replacement for 76385-313 in existing designs?

A: Yes. The 76385-313LF is mechanically and electrically compatible with 76385-313. Both parts share identical connector type, position count, pitch spacing, mounting method, and contact geometry. Direct substitution is possible without PCB redesign.

Q: What is the primary difference between these two part numbers?

A: The main differences are product status (obsolete versus active), RoHS compliance (non-compliant versus compliant), contact finish composition (tin-lead versus lead-free tin), and mating contact finish enhancement (standard gold versus GXT™ gold). Functionally, both parts perform identically in board-to-cable/wire applications.

Q: Why does 76385-313LF have a lower post contact finish thickness?

A: The reduced thickness (78.7µin versus 150.0µin) reflects lead-free manufacturing standards adopted in the active production version. This thickness remains within acceptable engineering parameters for solder joint reliability and contact performance.

Q: Is the GXT™ finish on 76385-313LF a performance upgrade?

A: GXT™ represents an enhanced gold plating specification that provides improved contact durability and wear resistance. This is a specification enhancement in the active part, not a requirement for compatibility.

Q: Which part should be selected for new designs?

A: For new designs, 76385-313LF is the appropriate selection as it carries active product status and RoHS compliance certification. The original 76385-313 is obsolete and intended for legacy system support only.

Q: Are there any packaging differences between these parts?

A: Yes. The 76385-313LF is supplied in tube packaging, while the original 76385-313 packaging specification is not detailed. Verify packaging requirements for your procurement and assembly processes.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity precautions are required during storage or handling.
