Key Parameters

Substitute Part Grouping Explanation

Substitution of the ST40X-18S-CV1 is based on electrical and mechanical parameter equivalence within the ST series rectangular connector family. The substitute part ST40X-18S-CV1(30) maintains identical specifications across all critical parameters: 18-position configuration, 0.020" (0.50mm) pitch, single-row layout, solder termination, gold contact finish, shielded design, and free-hanging mounting type. The primary distinction is product status and packaging format. The substitute part is active and available in tray packaging, whereas the original part is obsolete. Both parts share the same base product number (ST40X) and are manufactured by the same supplier, confirming functional equivalence.

Parameter Comparison

Electrical and mechanical parameter equivalence across all specified dimensions and termination characteristics. Both parts are manufactured by Hirose Electric Co Ltd within the same ST series family and share identical contact configurations, pitch spacing, and shielding specifications.

Product status and supply availability. The substitute part maintains active production status with confirmed inventory availability (1331 pcs), whereas the original part is obsolete.

Regulatory compliance. The substitute part carries ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for new designs and procurement.

Frequently Asked Questions (FAQ)

Q: Can ST40X-18S-CV1(30) be used as a direct replacement for ST40X-18S-CV1?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical contact count (18 positions), pitch spacing (0.020"/0.50mm), termination method (solder), contact finish (gold), and shielding characteristics. The primary difference is product status and packaging format.

Q: What is the significance of the "(30)" designation in ST40X-18S-CV1(30)?

A: The "(30)" designation indicates the packaging format (tray packaging with 30 units per tray). This is a packaging variant of the same connector, not a functional modification.

Q: Are there any compatibility concerns when substituting the obsolete part with the active equivalent?

A: No compatibility concerns exist. The substitute part maintains identical mechanical and electrical specifications, ensuring direct fit and functional equivalence in existing designs and applications.

Q: What compliance certifications apply to the substitute part?

A: The ST40X-18S-CV1(30) is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component procurement and use.

Q: Is the substitute part available in alternative packaging formats?

A: The provided data specifies tray packaging for the substitute part. Contact the manufacturer or authorized distributor for information regarding alternative packaging options.
