Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76384-403 is determined by strict equivalence across the following critical parameters:

• Connector Configuration: Header type with male pin contacts
• Position Count & Pitch: 3-position arrangement at 0.100" (2.54mm) mating pitch
• Mounting & Termination: Through-hole solder termination
• Mechanical Compatibility: Shrouded 2-wall design with matching contact geometry
• Material Specifications: Copper alloy contacts with thermoplastic glass-filled insulation rated UL94 V-0

The 76384-403LF meets all these criteria as a direct functional equivalent within the Dubox™ series.

Parameter Comparison

Engineering Selection Recommendations

The 76384-403LF is the direct active equivalent for the obsolete 76384-403. Selection between these parts should be based on the following criteria:

For New Designs and Procurement: The 76384-403LF is the appropriate choice. This part maintains identical mechanical and electrical interface specifications while offering active product status and RoHS compliance. The part is currently in production with established supply chain availability.

For Legacy System Support: The 76384-403 remains functionally compatible with existing assemblies designed to its specifications. However, procurement of this obsolete part may face extended lead times or availability constraints.

Compliance Considerations: The 76384-403LF carries RoHS compliance certification, whereas the 76384-403 does not. Applications subject to RoHS regulatory requirements must utilize the 76384-403LF variant.

Both parts share identical mechanical dimensions, contact geometry, and mounting characteristics, ensuring direct interchangeability at the assembly level.
