Key Parameters

Substitute Part Grouping Explanation

Substitution of the 76383-312 is determined by strict equivalence across the following critical parameters:

• Connector type, contact type, and gender (Header, Male Pin)
• Position count and row configuration (24 positions, 2 rows)
• Mating pitch and row spacing (0.100" / 2.54mm)
• Mounting orientation and method (Through Hole, Right Angle)
• Shrouding configuration (Shrouded - 2 Wall)
• Termination method (Solder)
• Fastening mechanism (Friction Lock)
• Contact material and insulation material specifications
• Flammability rating (UL94 V-0)

The 76383-312LF meets all these criteria and is classified as an active product, providing direct functional and mechanical compatibility with the obsolete 76383-312.

Parameter Comparison

Engineering Selection Recommendations

The 76383-312LF is the direct active equivalent for the obsolete 76383-312. Both components share identical mechanical and electrical specifications across all critical substitution parameters. The 76383-312LF offers the additional advantage of active product status, ensuring long-term availability and supply chain continuity.

The 76383-312LF carries RoHS compliance certification, whereas the 76383-312 is non-compliant. This distinction is relevant for applications subject to RoHS regulatory requirements. The 76383-312LF is also REACH Affected, compared to the REACH Unaffected status of the original part.

Both components are classified as MSL 1 (Unlimited moisture sensitivity level), indicating no special moisture handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can the 76383-312LF be used as a direct replacement for the 76383-312?

A: Yes. The 76383-312LF is mechanically and electrically equivalent to the 76383-312 across all critical parameters including pitch, position count, row configuration, mounting type, shrouding, and contact specifications.

Q: What is the primary difference between these two parts?

A: The 76383-312 is obsolete, while the 76383-312LF is an active product. The 76383-312LF also carries RoHS compliance certification, whereas the 76383-312 does not.

Q: Are there packaging differences between the 76383-312 and 76383-312LF?

A: The 76383-312LF is supplied in Tube packaging. The packaging specification for the 76383-312 is not provided in the technical data.

Q: Does the RoHS compliance difference affect compatibility?

A: RoHS compliance is a regulatory and material composition specification. Both parts are mechanically and functionally compatible. RoHS compliance of the 76383-312LF is relevant only if your application or end-market requires RoHS-compliant components.

Q: Are the contact finishes identical?

A: The mating contact finish is identical (Gold, GXT™ at 30.0µin thickness) for both parts. The post contact finish differs: the 76383-312 uses Tin-Lead at 150.0µin thickness, while the 76383-312LF uses Tin at 78.7µin thickness. Both finishes are compatible with standard solder termination processes.

Q: What is the operating temperature range?

A: The 76383-312LF operates across -40°C to 125°C. The operating temperature range for the 76383-312 is not specified in the technical data.

Q: Is the current rating specified for these connectors?

A: The 76383-312LF is rated for 3A. The current rating for the 76383-312 is not specified in the technical data.
