Substitute Part Grouping Explanation

Substitution of the ST40X-18S-CVR(80) is determined by strict equivalence across the following critical parameters:

• Connector Series & Type: ST series, plug configuration
• Electrical Interface: 18 positions, 0.020" (0.50mm) pitch, single row
• Termination Method: Solder termination with discrete wire
• Contact Properties: Gold plating at 8.00µin (0.203µm) thickness
• Mechanical Features: Shielded design, black housing, free-hanging in-line mounting
• Environmental Classification: MSL 1 (Unlimited)

The ST40X-18S-CVR(30) meets all these criteria and is classified as an active product, making it a direct functional equivalent. The primary difference is packaging format: the obsolete ST40X-18S-CVR(80) uses standard packaging, while the substitute uses tray packaging.

Parameter Comparison

Engineering Selection Recommendations

The ST40X-18S-CVR(30) is the direct substitute for the obsolete ST40X-18S-CVR(80). Selection is based on the following factors:

Product Status: The ST40X-18S-CVR(30) is active and maintains full manufacturing support, ensuring long-term availability and supply chain reliability.

Regulatory Compliance: The substitute part carries ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements. Both parts share identical ECCN and HTSUS classifications.

Functional Equivalence: All electrical and mechanical parameters are identical, including connector configuration, contact properties, termination method, and environmental ratings.

Packaging Consideration: The substitute uses tray packaging instead of standard packaging. This difference does not affect electrical or mechanical performance and is a standard industry practice for active products.

Frequently Asked Questions (FAQ)

Q: Can ST40X-18S-CVR(30) be used as a direct replacement for ST40X-18S-CVR(80)?

A: Yes. Both connectors are electrically and mechanically identical. They share the same 18-position configuration, 0.020" pitch, solder termination, gold contact finish, and shielded design. The only difference is packaging format.

Q: What does the suffix difference between (80) and (30) indicate?

A: The suffix designates packaging format. The (80) indicates standard packaging used for the obsolete variant, while (30) indicates tray packaging used for the active product. This is a manufacturing and logistics designation that does not affect connector performance or compatibility.

Q: Are there any compliance differences between the two parts?

A: The ST40X-18S-CVR(30) carries explicit ROHS3 and REACH certifications. Both parts share identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications, indicating equivalent export and tariff treatment.

Q: Is the tray packaging suitable for production assembly?

A: Yes. Tray packaging is standard for active connector products and is fully compatible with automated and manual assembly processes. It provides equivalent protection and handling characteristics to standard packaging.

Q: What is the inventory status of the substitute part?

A: The ST40X-18S-CVR(30) has 1,339 pieces in stock as new original inventory, providing immediate availability for procurement and assembly operations.
