Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ST40X-24S-CV1(80) is determined by strict alignment across the following critical parameters:

• Connector type (Plug)
• Number of positions (24)
• Pitch specification (0.020" / 0.50mm)
• Number of rows (1)
• Cable termination method (Solder)
• Shielded construction
• Contact finish (Gold) and finish thickness (8.00µin)
• Base product series (ST)
• Mounting configuration (Free Hanging In-Line)

The ST40X-24S-CV1(30) meets all substitution criteria as a direct equivalent within the ST series, with identical electrical and mechanical specifications. The primary distinction is product status: the substitute part is active and available, whereas the original part is obsolete.
