Key Parameters

Substitute Part Grouping Explanation

Substitution of the 76383-333 is determined by strict equivalence across the following critical parameters:

• Connector type, contact type, and pin configuration (66 positions, 2 rows)
• Mating pitch and row spacing (0.100" / 2.54mm)
• Mounting orientation and method (through-hole, right-angle)
• Shrouding design (shrouded 2-wall)
• Termination method (solder)
• Contact geometry and material composition
• Insulation material and flammability rating

The substitute part 76383-333LF maintains identical mechanical and electrical interface specifications, ensuring direct compatibility in applications originally designed for the 76383-333. The primary distinction is product status: the 76383-333LF is active and RoHS compliant, whereas the original part is obsolete and RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

The 76383-333LF is the direct active equivalent for the obsolete 76383-333. Selection of the substitute part is justified by:

• Identical mechanical interface and pin configuration, ensuring direct PCB compatibility
• Identical electrical contact specifications and mating characteristics
• Active product status with established supply chain availability
• RoHS compliance of the substitute part, meeting current regulatory requirements for new designs and production
• Equivalent reliability certifications and material specifications

For applications requiring the 76383-333, the 76383-333LF provides functional and mechanical interchangeability without design modification.
