AL8823S-13 LED Driver IC Equivalent & Substitute Parts

Part Overview

The AL8823S-13 is an AC DC offline switcher LED driver IC manufactured by Diodes Incorporated, designed for step-up (boost) topology applications in lighting systems. This part operates across a 5V to 36V supply range with a 1MHz switching frequency and is housed in an 8-SOIC package. The AL8823S-13 is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and production continuity. Substitute parts must maintain compatibility with the core electrical parameters and mounting requirements while offering active product status where available.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the AL8823S-13 is based on the following critical parameters: AC DC offline switcher topology, single output configuration, supply voltage range (5V to 36V minimum compatibility), surface mount packaging, and operating temperature range (-40°C to 105°C minimum). Substitute parts are grouped into two categories based on topology and package compatibility:

Category 1: Direct Topology Match (Step-Up Boost) AL8822SP-13 maintains the step-up boost topology with identical supply voltage range (5V to 36V), surface mount 8-SOIC package, and equivalent operating temperature range. This part includes an internal switch and offers 2A output current capability with active product status.

Category 2: Alternative Topology with Extended Capability LNK406EG, LNK409EG, LNK419LG, LYT0004D-TL, and LYT3315D-TL employ flyback or multi-topology architectures. These parts maintain AC DC offline switcher classification and single output configuration but operate across different supply voltage ranges and switching frequencies. LNK series parts support through-hole mounting, while LYT series parts offer surface mount options with expanded topology flexibility (flyback, SEPIC, step-down, step-up combinations).

Substitution eligibility requires matching: AC DC offline switcher type, single output requirement, surface mount or compatible mounting, and operating temperature compatibility with the target application.

Parameter Comparison

Engineering Selection Recommendations

AL8822SP-13 is the primary substitute for direct replacement in designs requiring step-up boost topology with 5V to 36V supply compatibility and surface mount 8-SOIC packaging. This part maintains identical electrical operating parameters and package footprint while offering active product status and internal switch capability rated at 2A output current. RoHS3 compliance and MSL 3 rating match the original specification.

LYT0004D-TL provides surface mount compatibility with multi-topology flexibility (flyback, SEPIC, step-down, step-up) for applications requiring AC DC offline switching across 85VAC to 308VAC input range. This part supports 225mA output current and maintains active product status with RoHS compliance and MSL 1 rating, offering superior moisture sensitivity performance.

LYT3315D-TL extends capability to 16-SOIC surface mount package with multi-topology support and triac dimming functionality across 85VAC to 132VAC input range. This part is suitable for lighting applications requiring dimming control and operates at -40°C to 150°C junction temperature range.

LNK406EG, LNK409EG, and LNK419LG are through-hole mounted alternatives from Power Integrations LinkSwitch-PH series, suitable for applications where through-hole mounting is acceptable. These parts support extended supply voltage range (36V to 725V) and higher operating temperature (-40°C to 150°C junction temperature). LNK406EG provides 1.5A output current with triac dimming, while LNK409EG and LNK419LG both provide 3.26A output current with triac and PWM dimming options respectively. All three maintain RoHS compliance and MSL 1 rating.

Selection should prioritize AL8822SP-13 for direct form-fit-function replacement. Alternative topologies should be selected only when application requirements explicitly demand extended supply voltage range, alternative dimming methods, or enhanced thermal performance.

Frequently Asked Questions (FAQ)

Q: Can AL8822SP-13 be used as a direct replacement for AL8823S-13? A: Yes. AL8822SP-13 maintains identical supply voltage range (5V to 36V), step-up boost topology, 1MHz switching frequency, surface mount 8-SOIC package, and operating temperature range (-40°C to 105°C). The primary difference is the addition of an internal switch and 2A output current rating in the AL8822SP-13, which provides enhanced capability while maintaining backward compatibility.

Q: What are the key differences between surface mount and through-hole substitute options? A: AL8822SP-13 and LYT series parts (LYT0004D-TL, LYT3315D-TL) are surface mount devices compatible with the original 8-SOIC or larger SOIC packages. LNK series parts (LNK406EG, LNK409EG, LNK419LG) are through-hole mounted in 7-SSIP packages with formed leads. Through-hole options require PCB redesign and are suitable only when mounting technology change is acceptable.

Q: Are all substitute parts RoHS compliant? A: Yes. All listed substitute parts maintain RoHS compliance. AL8822SP-13 and LYT3315D-TL are ROHS3 compliant, matching the original specification. LNK series and LYT0004D-TL parts are RoHS compliant.

Q: What is the significance of MSL (Moisture Sensitivity Level) differences? A: AL8823S-13 and AL8822SP-13 carry MSL 3 rating (168 hours maximum floor life). LNK series and LYT0004D-TL parts carry MSL 1 rating (unlimited floor life), indicating superior moisture resistance and reduced risk of moisture-induced failures during storage and handling. LYT3315D-TL maintains MSL 3 rating equivalent to the original part.

Q: Can LYT series parts replace AL8823S-13 in existing designs? A: LYT0004D-TL and LYT3315D-TL support step-up boost topology among multiple topology options but operate across different supply voltage ranges (85VAC to 308VAC or 85VAC to 132VAC respectively). These parts are suitable only for applications where AC input voltage compatibility is acceptable and PCB layout modifications can accommodate different package sizes (8-SOIC for LYT0004D-TL, 16-SOIC for LYT3315D-TL).

Q: What output current capabilities do substitute parts provide? A: AL8822SP-13 provides 2A output current. LNK406EG provides 1.5A. LNK409EG and LNK419LG both provide 3.26A. LYT0004D-TL provides 225mA. LYT3315D-TL does not specify output current in the provided parameters. Selection should match application current requirements.

Q: Are dimming capabilities available in substitute parts? A: AL8823S-13 does not specify dimming capability. AL8822SP-13 does not specify dimming capability. LNK406EG and LYT3315D-TL support triac dimming. LNK419LG supports PWM dimming. LNK409EG supports triac dimming. LYT0004D-TL does not specify dimming capability. Dimming selection depends on application requirements.
