Key Parameters

Substitute Part Grouping Explanation

Substitution for the 73983-1021 is determined by strict equivalence across the following critical parameters:

• Connector type and style (Header, Male Pins, High Speed)
• Number of positions and contact layout (36 positions, 30 Signal / 6 Ground)
• Pitch specification (0.079" / 2.00mm)
• Mounting configuration (Through Hole, Press-Fit termination)
• Electrical ratings (1A current, UL94 V-0 flammability)
• Physical construction (Shielded, 5-row configuration)
• Contact material and finish (Gold plating, 30.0µin thickness)
• Operating temperature range (-55°C to 105°C)

The substitute part 73983-1021LF maintains identical electrical and mechanical specifications while offering active product status and improved compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations
