LTST-C150CKT-DSC LED Red Clear 1206 SMD Equivalent & Substitute Parts

Part Overview

The LTST-C150CKT-DSC is a red LED indication component manufactured by Lite-On Inc. in 1206 (3216 Metric) surface mount package format. This part is classified as obsolete and has been discontinued from active production. The component features a red 638nm wavelength emission with a clear colorless lens and 10mcd brightness rating, designed for discrete LED indication applications requiring 1.8V forward voltage operation at 20mA test current.

Due to its obsolete status, sourcing the LTST-C150CKT-DSC from active inventory channels is no longer available through standard distribution. Identification of functionally equivalent substitute components is necessary to maintain design continuity and support ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete LTST-C150CKT-DSC is based on the following critical parameters that define functional equivalence:

Primary Substitution Criteria:

• Base product number alignment (LTST-C150 series)
• Package compatibility (1206 / 3216 Metric surface mount)
• Mounting type (Surface Mount)
• Manufacturer consistency (Lite-On Inc.)
• Regulatory compliance (RoHS3, REACH Unaffected)
• Moisture sensitivity level (MSL 3)

The substitute part LTST-C150KDKT-10A shares the same base product number (LTST-C150) and is manufactured by the same supplier (Lite-On Inc.), indicating design lineage and functional relationship. Both components maintain identical package specifications and regulatory compliance status, establishing the foundation for substitution eligibility.

The substitute part carries active product status, ensuring ongoing availability through standard distribution channels and manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

Substitution Eligibility:

The LTST-C150KDKT-10A is designated as a substitute for the obsolete LTST-C150CKT-DSC based on shared base product number designation and identical regulatory compliance certifications. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements for equivalent application.

Product Status Consideration:

The LTST-C150CKT-DSC is classified as obsolete with no active manufacturing support. The LTST-C150KDKT-10A maintains active product status with confirmed inventory availability (813 pieces), providing assured supply chain continuity for ongoing production and replacement requirements.

Compliance Alignment:

Both components share identical moisture sensitivity level specifications (MSL 3, 168 Hours) and regulatory certifications, ensuring compatibility with existing assembly and storage protocols without modification to handling procedures.

Selection Basis:

Component selection should prioritize the active substitute part (LTST-C150KDKT-10A) to ensure long-term supply availability and manufacturing support. The shared base product number and identical compliance certifications establish functional equivalence for direct substitution in applications previously specified for the LTST-C150CKT-DSC.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the LTST-C150CKT-DSC?

A: The LTST-C150CKT-DSC is classified as obsolete and no longer manufactured. The LTST-C150KDKT-10A provides an active alternative with identical regulatory compliance and shared base product number designation.

Q: Are the package specifications identical between the main part and substitute?

A: Both components are manufactured by Lite-On Inc. and share the same base product number (LTST-C150). The main part specifies 1206 (3216 Metric) package format. Complete package specification data for the substitute part is not provided in the available technical documentation.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the LTST-C150CKT-DSC and LTST-C150KDKT-10A maintain ROHS3 compliance and REACH unaffected status. Both components carry identical moisture sensitivity level specifications (MSL 3, 168 Hours).

Q: What is the inventory status for each part?

A: The obsolete LTST-C150CKT-DSC has 919 pieces available in current stock. The active substitute LTST-C150KDKT-10A has 813 pieces available in current stock.

Q: Can the LTST-C150KDKT-10A be used as a direct replacement in existing designs?

A: The LTST-C150KDKT-10A shares the same base product number and regulatory certifications as the LTST-C150CKT-DSC. Verification of complete package and electrical specifications against your specific application requirements is necessary before implementation.

Q: What is the significance of the shared base product number?

A: The identical base product number (LTST-C150) indicates design lineage and functional relationship between components within the Lite-On Inc. product family. This designation supports substitution eligibility based on manufacturer design continuity.

Q: Are there any differences in moisture sensitivity handling between the two parts?

A: No. Both components carry identical MSL 3 (168 Hours) specifications, requiring identical storage, handling, and assembly procedures without modification to existing protocols.
