Key Parameters

Substitute Part Grouping Explanation

Substitution of the ST40X-10S-CV(80) is determined by strict equivalence across the following critical parameters:

• Connector type (Plug)
• Number of positions (10)
• Pitch specification (0.020" / 0.50mm)
• Number of rows (1)
• Cable termination method (Solder)
• Contact finish material (Gold)
• Contact finish thickness (8.00µin / 0.203µm)
• Shielded feature requirement
• Color specification (Black)

The ST40X-10S-CV(30) satisfies all these parameters and is classified as an active product, making it a direct functional equivalent suitable for replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The ST40X-10S-CV(30) is the direct equivalent for the obsolete ST40X-10S-CV(80). Both parts share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: ST40X-10S-CV(30) is active and maintains full manufacturing support, while ST40X-10S-CV(80) is obsolete.

The ST40X-10S-CV(30) carries RoHS3 compliance and REACH unaffected status, providing regulatory alignment for new designs and ongoing production. Both parts maintain identical MSL classification (1 - Unlimited) and export control designations (EAR99), ensuring compatibility in regulated environments.

Frequently Asked Questions (FAQ)

Q: Are ST40X-10S-CV(80) and ST40X-10S-CV(30) electrically interchangeable?
