Equivalent & Substitute Parts Reference for RBD-12-0.35

Part Overview

The Recom Power RBD-12-0.35 is a constant current LED driver utilizing a buck-boost topology and providing a maximum output of 350mA over a wide output voltage range of 2 to 40V. The part is designed for through-hole mounting and features remote On/Off functionality, over-temperature protection (OTP), and short-circuit protection (SCP). With a compact 7-DIP module package and full RoHS3 compliance, it supports analog and PWM dimming. The RBD-12-0.35 is now listed as Obsolete, making it necessary to identify viable alternative models for ongoing designs or replacements in existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for constant current LED drivers within the buck-boost category utilizes the following explicit parameters: topology (buck-boost), output current rating (350mA maximum), input and output voltage ranges (Input: 8V–36V / Output: 2V–40V), number of outputs (1), dimming method, operating temperature range, protection features, mounting style, package type and dimensions, regulatory approvals, and compliance status. Only models matching these characteristics are included as substitutes.

Parameter Comparison

Engineering Selection Recommendations

The primary selection driver is the obsolete status of RBD-12-0.35. Substitute models must be RoHS3 compliant and REACH unaffected to ensure regulatory alignment and maintain environmental compliance. The LDB-350L from MEAN WELL USA Inc. provides an active product status and matches these criteria. Both parts feature CE approval; however, cULus and EN certifications are unique to RBD-12-0.35 and not present on the LDB-350L. Mechanical fit, packaging, and mounting type should be validated against available documentation to confirm compatibility.

Frequently Asked Questions (FAQ)

Q1: What electrical parameters are critical for substitution between RBD-12-0.35 and LDB-350L? A1: Key electrical parameters include topology (buck-boost), maximum output current (350mA), input voltage range, output voltage range, and dimming method.

Q2: How does packaging affect substitution decisions? A2: RBD-12-0.35 is a 7-DIP module, while LDB-350L utilizes a 24-DIP module with 9 leads. Physical size and lead configuration must be considered to ensure proper board fit.

Q3: Are protection features comparable between parts? A3: Both models offer remote On/Off, over-temperature protection (OTP), and short-circuit protection (SCP).

Q4: What compliance certifications must be matched when selecting a substitute? A4: Both parts are RoHS3 compliant and REACH unaffected. CE approval is present on both; cULus and EN certifications are exclusive to RBD-12-0.35.

Q5: Can both drivers be used for single-output constant current applications? A5: Both RBD-12-0.35 and LDB-350L are specified for single-output, constant current operation.

Q6: Are there differences in operating temperature and efficiency? A6: RBD-12-0.35 operates at -40°C to 75°C with 92% efficiency. LDB-350L operates at -40°C to 71°C with 90% efficiency.

Q7: Is mounting style consistent between products? A7: Both models are designed for through-hole mounting. Precise dimensional checks are required for mechanical compatibility.
