Substitute Part Grouping Explanation

Substitution of the obsolete LTST-C150CKT-CS is based on alignment with the base product number LTST-C150 and shared manufacturing lineage from Lite-On Inc. The substitute part LTST-C150KDKT-10A maintains the same base product designation and package classification, ensuring mechanical and electrical compatibility within the 1206 surface mount form factor.

The substitution logic is determined by the following critical parameters:

• Base Product Number: LTST-C150
• Manufacturer: Lite-On Inc.
• Package / Case: 1206 (3216 Metric)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 3 (168 Hours)

The substitute part LTST-C150KDKT-10A is classified as active product status, providing continued availability and supply chain continuity for applications requiring the LTST-C150 series LED indication component.

Parameter Comparison

Engineering Selection Recommendations

The LTST-C150KDKT-10A is the designated substitute for the obsolete LTST-C150CKT-CS based on shared base product lineage and identical compliance certifications. Both components maintain ROHS3 compliance and identical moisture sensitivity specifications, ensuring regulatory and environmental compatibility.

The substitute part is currently in active production status with confirmed inventory availability (813 Pcs), providing reliable procurement for new designs and legacy system updates. The LTST-C150KDKT-10A retains the same 1206 surface mount package footprint and mechanical dimensions, enabling direct board-level substitution without PCB redesign.

Selection of the LTST-C150KDKT-10A eliminates obsolescence risk while maintaining full compliance with RoHS3 and REACH regulatory requirements applicable to the original component.

Frequently Asked Questions (FAQ)

Q: Can the LTST-C150KDKT-10A be used as a direct replacement for the LTST-C150CKT-CS?

A: Yes. Both components share the LTST-C150 base product number, identical 1206 (3216 Metric) package specifications, and matching RoHS3 and MSL certifications. The substitute part is mechanically and electrically compatible for surface mount applications.

Q: What is the primary reason for substitution?

A: The LTST-C150CKT-CS is classified as obsolete product status. The LTST-C150KDKT-10A is an active product from the same manufacturer and product series, ensuring continued supply chain availability.

Q: Are there differences in electrical specifications between the two parts?

A: Electrical parameter data is not provided for the LTST-C150KDKT-10A in the available documentation. Substitution is based on shared base product designation and identical package/compliance specifications. Detailed electrical characteristics should be confirmed through the manufacturer's current datasheet for the active part number.

Q: Does the substitute part maintain the same PCB footprint?

A: Yes. Both components use the 1206 (3216 Metric) surface mount package with identical mechanical dimensions (3.20mm L x 1.60mm W, 1.20mm max height), ensuring footprint compatibility without PCB layout modifications.

Q: Are moisture sensitivity and RoHS compliance identical?

A: Yes. Both the LTST-C150CKT-CS and LTST-C150KDKT-10A maintain MSL 3 (168 Hours) rating and ROHS3 compliance, with REACH unaffected status for both components.
