Equivalent & Substitute Parts for LDB-350L

Part Overview

The MEAN WELL USA Inc. LDB-350L is an active, through-hole constant current LED driver utilizing a buck-boost topology, delivering up to 350mA output current across a 2–40V output range from a 9–36V input. It features remote on/off, overtemperature protection, short-circuit protection, and supports PWM dimming. Due to inventory considerations, product lifecycle status, or multi-sourcing requirements, identifying compatible alternative models with equivalent electrical, mechanical, and compliance parameters is essential.

Engineering Selection Recommendations

When selecting substitutes for LDB-350L, consider product status, RoHS compliance, and regulatory approvals as provided. LDB-350L is active and ROHS3 compliant. RBD-12-0.35 is listed as obsolete, though also ROHS3 compliant and REACH unaffected. Both parts list CE approval, with RBD-12-0.35 providing additional cULus and EN certifications. Confirm that current compliance and approval requirements align with the intended application environment.

Frequently Asked Questions (FAQ)

Q: What are the key criteria for selecting substitute parts for LDB-350L?
A: The key criteria are matching electrical specifications (output current, input/output voltage range, topology, and dimming capabilities), protection features, mounting type, package, physical dimensions, and regulatory compliance.

Q: Are RBD-12-0.35 and LDB-350L electrically compatible?
A: Both devices are constant current, buck-boost topology LED drivers with identical output current (350mA), voltage range (2 ~ 40V), and include similar protection features and dimming support as specified.

Q: Can the RBD-12-0.35 be used in the same PCB footprint as LDB-350L?
A: Mechanical differences exist: LDB-350L uses a 24-DIP module (9 leads), whereas RBD-12-0.35 uses a 7-DIP module. Direct footprint compatibility must be confirmed with the actual physical package and PCB layout.

Q: Do substitute parts meet the same compliance requirements?
A: Both LDB-350L and RBD-12-0.35 are ROHS3 compliant, carry CE approval, and are REACH unaffected per the provided data.

Q: Does product status affect substitution?
A: LDB-350L is active, while RBD-12-0.35 is obsolete. Substitute selection must consider product availability and lifecycle requirements as provided.
