AL5890-40D-13 LED Driver IC: Equivalent & Substitute Parts

Part Overview

The AL5890-40D-13 is a linear LED driver IC manufactured by Diodes Incorporated, designed for single-output lighting and signage applications. This part operates with a supply voltage range of 7V to 400V and delivers a maximum output current of 40mA in a TO-252 (DPAK) surface mount package. The AL5890-40D-13 is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain compatibility with the TO-252 package form factor and support the electrical specifications required for LED driver functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AL5890-40D-13 are selected based on the following critical parameters:

Primary Substitution Criteria:

• Linear topology with single output configuration
• Surface mount packaging (TO-252 DPAK or equivalent form factors)
• Output current capability within or exceeding 40mA
• Supply voltage range compatibility (minimum 7V or lower, maximum 400V or higher)
• RoHS3 compliance and REACH unaffected status
• Operating temperature range of -40°C to 105°C or broader
• Applications in lighting and signage

Substitution Logic: Parts are grouped into two categories based on functional compatibility:

1. Direct Package Substitutes (TO-252 DPAK): AL5810D-13 and CL520K4-G maintain the same TO-252 package footprint, enabling direct PCB replacement with minimal layout modifications.

2. Functional Equivalents (Alternative Packages): IS32LT3175P-GRLA3-TR, MAX16836ASA+T, MAX16839ASA+T, and TSCR420CX6 RFG provide equivalent LED driver functionality with higher output current capabilities or enhanced features (PWM dimming), though they require different package footprints and PCB layout adjustments.

All substitute parts maintain ROHS3 compliance and are suitable for lighting and signage applications.

Parameter Comparison

Engineering Selection Recommendations

For Direct PCB Replacement (Same Footprint):

AL5810D-13 is the primary recommended substitute. It maintains the TO-252 DPAK package, enabling direct PCB replacement without layout modifications. The part is active status with AEC-Q100 automotive qualification, ROHS3 compliance, and improved MSL rating (1 vs. 3). Output current of 200mA exceeds the original 40mA specification, providing design margin. Supply voltage range of 2.5V to 60V is narrower than the original 400V maximum, requiring verification against application requirements.

CL520K4-G provides an alternative TO-252 DPAK substitute with active status and extended operating temperature range (-40°C to 125°C). Output current of 20mA is lower than the original 40mA, limiting suitability to lower-power LED applications. Supply voltage range of 4.75V to 90V is compatible with most lighting and signage designs.

For Enhanced Functionality (Alternative Packages):

IS32LT3175P-GRLA3-TR, MAX16836ASA+T, and MAX16839ASA+T are active-status alternatives offering PWM dimming capability and higher output current ratings. These parts require PCB layout redesign due to different package footprints (8-SOIC-EP vs. TO-252 DPAK). All three carry AEC-Q100 or equivalent automotive qualification and ROHS3 compliance. Selection depends on required output current: MAX16839ASA+T (100mA), IS32LT3175P-GRLA3-TR (150mA), or MAX16836ASA+T (350mA).

Avoid:

TSCR420CX6 RFG is classified as obsolete and carries lower output current (11mA), making it unsuitable for replacement applications requiring 40mA or higher.

BCR402WH6327XTSA1 has a maximum supply voltage of 18V, which is insufficient for the original part's 400V specification and most high-voltage signage applications.

Frequently Asked Questions (FAQ)

Q: Can AL5810D-13 directly replace AL5890-40D-13 on the PCB?

A: Yes. Both parts use the TO-252 DPAK package with identical pinout and footprint. No PCB layout modifications are required. However, verify that the application can tolerate the narrower supply voltage range (2.5V to 60V vs. 7V to 400V).

Q: What is the key difference between AL5890-40D-13 and AL5810D-13?

A: The AL5810D-13 adds PWM dimming capability, increases output current to 200mA, and reduces the maximum supply voltage from 400V to 60V. The AL5890-40D-13 has no dimming function and supports higher supply voltages.

Q: Why do some substitutes use different packages (8-SOIC-EP instead of TO-252)?

A: Different packages offer trade-offs in thermal performance, board space, and manufacturing capabilities. 8-SOIC-EP packages provide better thermal dissipation through exposed pads, beneficial for higher output current applications. Package selection depends on PCB layout constraints and thermal requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements equivalent to the original AL5890-40D-13.

Q: Which substitute supports the highest output current?

A: MAX16836ASA+T delivers 350mA output current, the highest among all listed substitutes. This part is suitable for multi-LED or high-brightness applications requiring significant current delivery.

Q: Can I use TSCR420CX6 RFG as a substitute?

A: TSCR420CX6 RFG is obsolete and delivers only 11mA output current, insufficient for applications requiring 40mA. This part is not recommended for new designs or production.

Q: What is the operating temperature range compatibility?

A: AL5890-40D-13 operates from -40°C to 105°C. Most active substitutes (AL5810D-13, IS32LT3175P-GRLA3-TR, MAX16836ASA+T, MAX16839ASA+T) extend this to -40°C to 125°C, providing broader environmental tolerance. TSCR420CX6 RFG supports -55°C to 150°C but is obsolete.

Q: Is automotive qualification required for my application?

A: AL5810D-13, IS32LT3175P-GRLA3-TR, MAX16836ASA+T, and MAX16839ASA+T carry AEC-Q100 or AEC-Q101 automotive qualification. If your application requires automotive-grade components, select from these parts. CL520K4-G and BCR402WH6327XTSA1 lack explicit automotive qualification in the provided specifications.
