Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 50003-1232H is determined by strict equivalence across the following critical parameters:

• Connector type and style (Receptacle, Female Sockets, High Density)
• Position count and configuration (232 positions, 4×58 arrangement)
• Pitch specification (0.100" / 2.54mm)
• Mounting method (Through Hole, Right Angle)
• Termination type (Solder)
• Contact finish and thickness (Gold, 30.0µin)
• Presence of mating guide feature
• Base product number alignment (50003 series)

The substitute part 50003-1232HLF meets all these criteria while offering improved product status and compliance characteristics.
