Key Parameters

Substitute Part Grouping Explanation

The ST40X-36S-CV(30) qualifies as a direct substitute for the ST40X-36S-CV(80) based on the following critical parameters that determine functional and mechanical compatibility:

• Identical connector type (Plug)
• Identical number of positions (36)
• Identical pitch (0.020" / 0.50mm)
• Identical number of rows (1)
• Identical cable termination method (Solder)
• Identical contact finish (Gold) and finish thickness (8.00µin / 0.203µm)
• Identical shielded feature
• Identical color (Black)
• Identical mounting type (Free Hanging / In-Line)
• Identical base product number (ST40X)
• Identical MSL rating (1 / Unlimited)

The substitution is valid across all electrical and mechanical interfaces. The primary difference is product status: ST40X-36S-CV(80) is obsolete, while ST40X-36S-CV(30) is active and available.
