Key Parameters

Substitute Part Grouping Explanation

Substitution is performed by strictly matching the following key parameters: function (constant current LED driver), topology (buck), number of outputs (1), maximum output current, input and output voltage ranges, dimming capability, protection features, mounting type, package form factor, compliance status (RoHS, REACH), operating temperature, efficiency, and relevant certifications. Only parts conforming exactly to these defined categories and values are eligible as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The LDD-1000LS is designated as obsolete. Substitute selection within this category must prioritize continued RoHS3 and REACH compliance and corresponding certification (CE) status as provided. The substitute NLDD-1050H is listed as active, is RoHS3 compliant, REACH unaffected, and carries CE approval. These compliance and status characteristics are essential for ongoing manufacturing and regulatory compatibility.

Frequently Asked Questions (FAQ)

Q1: What key parameters must match to substitute a constant current LED driver like LDD-1000LS?
A1: Functional type (constant current), topology (buck), maximum output current, input and output voltage ranges, number of outputs, dimming capability, features (such as protections), and compliance (RoHS, REACH, certifications) must all be matched.

Q2: Are all physical packages directly interchangeable?
A2: Physical compatibility requires equal or compatible mounting type and package/case definitions. The LDD-1000LS uses surface mount, 24-SMD module; substitutes may have different mounting or lead configurations.

Q3: Is compliance with RoHS and REACH mandatory for substitutes?
A3: Compliance must be maintained at the same level as the original part for regulatory and application requirements where these standards are relevant.

Q4: How does product status affect substitution decisions?
A4: Selecting an active status substitute ensures continuous supply and manufacturer support for the part’s lifecycle. Obsolete substitutes do not fulfill this requirement.

Q5: Can substitute parts differ in efficiency, features, or operating temperature?
A5: Only the values provided can be used for evaluation. Substitution is permitted only when these parameters meet or exceed those of the original. Alternative parameters are not considered unless explicitly specified.
