Key Parameters

Substitute Part Grouping Explanation

Substitution of the ST80X-18S(50) is determined by the following critical parameters that must remain constant:

• Number of Positions: 18 positions (fixed requirement)
• Pitch - Mating: 0.039" (1.00mm) (fixed requirement)
• Mounting Type: Surface Mount (fixed requirement)
• Termination: Solder (fixed requirement)
• Current Rating: 0.5A (fixed requirement)
• Voltage Rating: 100V (fixed requirement)
• Operating Temperature Range: -30°C ~ 80°C (fixed requirement)
• Connector Type: Plug, Cradle (fixed requirement)
• Contact Type: Non-Gendered (fixed requirement)
• Insulation Material: Polyamide (PA), Nylon (fixed requirement)

The ST80X-18S(30) qualifies as a direct substitute because it maintains all critical electrical and mechanical parameters while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations
