Amphenol ICC 76383-405 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76383-405 is a shrouded rectangular connector header designed for through-hole, right-angle board-to-cable/wire applications. This 10-position, 2-row connector operates at 0.100" (2.54mm) pitch and features solder termination with friction lock fastening. The part is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production requirements.

Substitute Part Grouping Explanation

The 76383-405LF serves as a direct functional equivalent to the 76383-405. Substitution is based on matching the following critical parameters:

Connector type, contact type, and gender (Header, Male Pin)
Position count and row configuration (10 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)
Contact material and insulation material (Phosphor Bronze, Polyester Glass Filled)
Flammability rating (UL94 V-0)

The primary distinction between these parts is product status and compliance certification, not electrical or mechanical function.

Engineering Selection Recommendations

The 76383-405LF is the active equivalent for the obsolete 76383-405. Both parts share identical electrical and mechanical specifications within the Dubox™ series. Selection between these parts is determined by regulatory and compliance requirements:

76383-405LF is recommended for:

New product designs requiring active component availability
Applications subject to RoHS compliance requirements
Designs requiring documented operating temperature range (-40°C ~ 125°C)
Designs requiring documented current rating (3A)
Applications subject to REACH compliance

76383-405 considerations:

Existing inventory of 834 pieces available
Suitable only for legacy systems or non-regulated applications
RoHS non-compliant status restricts use in regulated markets

Both parts are mechanically and electrically interchangeable at the connector interface level. The transition from 76383-405 to 76383-405LF involves compliance certification changes and contact finish specifications (Tin-Lead to Tin), not functional performance differences.

Frequently Asked Questions (FAQ)

Q: Are the 76383-405 and 76383-405LF mechanically interchangeable?

A: Yes. Both parts feature identical mounting type (through hole, right angle), shrouding configuration (shrouded - 2 wall), position count (10 positions, 2 rows), and pitch (0.100" / 2.54mm). They occupy the same footprint and mate with identical connector receptacles.

Q: What is the difference between the contact finishes?

A: The 76383-405 uses Tin-Lead contact finish at 150.0µin (3.81µm) thickness. The 76383-405LF uses Tin contact finish at 78.7µin (2.00µm) thickness. Both finishes are applied to Phosphor Bronze contact material. The Tin finish in the 76383-405LF reflects RoHS compliance requirements.

Q: Why is the 76383-405 classified as obsolete?

A: The 76383-405 is obsolete due to RoHS non-compliance and lack of documented operating specifications. The 76383-405LF represents the current active product meeting modern regulatory standards.

Q: Can I use the 76383-405 in new designs?

A: The 76383-405 is suitable only for legacy system maintenance or non-regulated applications. New designs should specify the 76383-405LF to ensure compliance with RoHS and REACH regulations and to maintain long-term component availability.

Q: What is the current rating for these connectors?

A: The 76383-405LF is rated for 3A. The 76383-405 does not have a documented current rating in the available specifications.

Q: Are there packaging differences between these parts?

A: The 76383-405LF is supplied in bulk packaging. The 76383-405 packaging type is not specified. Confirm packaging requirements with your procurement process.
