Equivalent & Substitute Parts for LDD-1200L

Part Overview

The LDD-1200L, manufactured by MEAN WELL USA Inc., is an obsolete 1.2A constant current LED driver featuring a buck topology and a single output channel. This driver operates within a 2–30V output voltage range and accepts 6–36V input. With additional features such as analog/PWM dimming, remote on/off, and SCP, the device was widely used for efficient LED lighting designs. Given its obsolete product status, it is necessary to identify alternative models that deliver similar electrical and mechanical performance while fulfilling compliance and inventory needs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LDD-1200L are identified strictly using these key parameters: topology (buck), type (constant current), output configuration (single channel), input and output voltage ranges, maximum output current, dimming methods, efficiency, features, package type, compliance status (RoHS, REACH), approval certifications, and mounting. Only models matching the critical electrical, mechanical, and compliance requirements are considered equivalent substitutes.

Parameter Comparison

Engineering Selection Recommendations

Selection of NLDD-1200H as a substitute for LDD-1200L is based on continued active product status, matching RoHS3 compliance, and identical approval certifications (CE). Both parts are classified under the same ECCN and HTSUS and have the same moisture sensitivity level and REACH status. Both utilize a 24-DIP Module, 9 Leads package with through-hole mounting.

Frequently Asked Questions (FAQ)
