LC5225D Equivalent & Substitute Parts

Part Overview

The LC5225D is an LED Driver IC manufactured by Sanken Electric USA Inc., designed for AC DC offline switching applications with PWM dimming capability. This component operates as a 1-output switcher supporting both step-down (buck) and step-up (boost) topologies with an internal switch and 400mA output current rating. The part is classified as obsolete, making equivalent substitute components necessary for new designs and ongoing production requirements. The LC5225D is packaged in an 8-DIP configuration with through-hole mounting and operates across a wide supply voltage range of 25V to 400V.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LC5225D requires matching on the following critical parameters: AC DC offline switcher topology, single output configuration, PWM dimming capability, and internal switch presence. The LC5225D operates across 25V–400V supply range with 400mA output current and through-hole 8-DIP packaging.

Substitute parts are grouped into two categories based on compatibility:

Category A: Direct Functional Equivalents (Topology & Dimming Match) Parts AL9910A-5S-13, MP4088GS-Z, TPS92075D/NOPB, and TPS92075DR/NOPB maintain the step-down/step-up (buck/boost) topology with PWM dimming. These parts support AC DC offline switching with single outputs and internal or external switch configurations. However, all Category A substitutes use surface-mount packaging (8-SOIC or 16-SOIC) rather than through-hole 8-DIP, requiring PCB redesign.

Category B: Functional Alternatives (Topology Match, Dimming Variation) Parts MP4060GS-Z and MP4068GN provide buck/boost topology but employ TRIAC dimming instead of PWM. These parts are suitable for applications where TRIAC dimming is acceptable and offer active product status with extended temperature ratings.

Substitution logic is constrained by: (1) AC DC offline switcher type requirement, (2) single output configuration, (3) buck/boost topology support, (4) dimming method compatibility, and (5) package form factor availability.

Parameter Comparison

Engineering Selection Recommendations

Selection of substitute parts for the LC5225D must account for product status and compliance certifications. All identified substitute parts maintain active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment.

For PWM Dimming Applications: AL9910A-5S-13 is the primary substitute when PWM dimming functionality is required. This part supports both analog and PWM dimming modes, maintains buck/boost topology, and carries active product status. The part operates across -40°C to 85°C, which is within the LC5225D operating range. Surface-mount 8-SOIC packaging requires PCB redesign from the original through-hole 8-DIP configuration.

For TRIAC Dimming Applications: MP4088GS-Z and TPS92075DR/NOPB are suitable when TRIAC dimming is acceptable. MP4088GS-Z offers extended temperature rating (-40°C to 125°C) and active product status. TPS92075DR/NOPB provides tape and reel packaging for production volumes and maintains the same temperature range. Both parts require surface-mount PCB implementation.

For Extended Temperature Requirements: MP4088GS-Z and TPS92075D/NOPB extend the upper operating temperature to 125°C, exceeding the LC5225D specification of 105°C. These parts are appropriate for applications requiring enhanced thermal performance.

All substitute parts carry ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can AL9910A-5S-13 directly replace LC5225D without PCB modification? A: No. AL9910A-5S-13 uses 8-SOIC surface-mount packaging while LC5225D uses 8-DIP through-hole packaging. PCB redesign is required. However, AL9910A-5S-13 maintains functional equivalence with PWM dimming support and buck/boost topology.

Q: What is the primary difference between PWM and TRIAC dimming substitutes? A: LC5225D uses PWM dimming. AL9910A-5S-13 supports both PWM and analog dimming. MP4088GS-Z, TPS92075D/NOPB, and TPS92075DR/NOPB use TRIAC dimming. TRIAC dimming is suitable for AC line-dimmer applications, while PWM dimming is used for DC control circuits. Application requirements determine which dimming method is appropriate.

Q: Are all substitute parts RoHS compliant? A: Yes. All identified substitutes carry ROHS3 compliance. LC5225D is RoHS compliant. All substitutes maintain or exceed this compliance level.

Q: Which substitute offers the widest operating temperature range? A: MP4088GS-Z and TPS92075D/NOPB both operate from -40°C to 125°C, extending 20°C above the LC5225D specification of -40°C to 105°C.

Q: Can MP4060GS-Z be used in applications requiring PWM dimming? A: No. MP4060GS-Z uses TRIAC dimming only. It is suitable only for applications where TRIAC dimming is the control method.

Q: What inventory status should be considered for production planning? A: AL9910A-5S-13 has 5400 pcs in stock, MP4088GS-Z has 4639 pcs, TPS92075DR/NOPB has 2293 pcs, and TPS92075D/NOPB has 1126 pcs. All substitutes maintain active product status with available inventory.
