Key Parameters

Substitute Part Grouping Explanation

Substitution for the AL5890-15D-13 is determined by the following critical parameters:

• Output Current Capability: The original part delivers 15mA. Substitutes must support this current level or higher.
• Supply Voltage Range: Operating range of 7V to 400V defines the input voltage compatibility window.
• Package Type: TO-252 (DPAK) surface mount package is the primary form factor.
• Dimming Functionality: The original part has no dimming capability; substitutes may include PWM dimming as an enhancement.
• Product Status: Active substitutes are preferred over obsolete alternatives for long-term availability.
• Compliance Standards: RoHS3 compliance and automotive qualification (where applicable) ensure regulatory alignment.

Substitute parts are grouped into two categories:

1. Parametric Equivalents: Parts with identical or superior electrical specifications and compatible packaging.
2. Manufacturer Recommended Alternatives: Active production parts from established manufacturers offering enhanced features or improved availability.

Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalent: AL5890-20D-13 is the closest parametric match, offering identical supply voltage range (7V to 400V), same package type (TO-252 DPAK), and compatible operating temperature range. The 20mA output current exceeds the original 15mA specification, providing design margin. However, this part shares obsolete status with the original device.

Manufacturer Recommended Active Substitutes:

AL5810D-13 (Diodes Incorporated) is the manufacturer-recommended replacement. It maintains TO-252 DPAK packaging and identical operating temperature range. The part features PWM dimming capability and internal switching, enhancing design flexibility. Supply voltage range is reduced to 2.5V to 60V, which may require circuit redesign for high-voltage applications. AEC-Q100 automotive qualification and MSL-1 rating provide superior reliability characteristics.

APS13568ELJATR (Allegro MicroSystems) offers PWM dimming and 150mA output current in an 8-SOIC-EP package. Supply voltage is limited to 7V to 24V, restricting use in high-voltage circuits. This part is suitable for standard lighting applications within the specified voltage window.

MAX16836ATE+ (Analog Devices/Maxim Integrated) delivers 350mA output current with PWM dimming in a 16-TQFN package. Supply voltage range of 6.5V to 40V accommodates moderate-voltage designs. Automotive qualification and extended operating temperature (-40°C to 125°C) support demanding applications. Package change requires PCB layout modification.

NUD4001DR2G (onsemi) provides 500mA output current with PWM dimming in an 8-SOIC package. Supply voltage range of 3.6V to 30V suits low-to-moderate voltage circuits. Automotive qualification and extended temperature range support industrial and automotive lighting applications.

LP5522TM/NOPB (Texas Instruments) is a compact 6-DSBGA solution with 20mA output current and dimming capability. Supply voltage is restricted to 2.7V to 5.5V, limiting application to low-voltage circuits. MSL-1 rating and active production status ensure long-term availability for consumer lighting applications.

Selection Criteria:

• For high-voltage applications (>60V): AL5890-20D-13 or AL5890-15D-13 remain necessary; no active substitute maintains 400V capability.
• For standard voltage circuits (7V to 40V) with dimming: AL5810D-13, MAX16836ATE+, or NUD4001DR2G.
• For automotive applications: AL5810D-13, MAX16836ATE+, or NUD4001DR2G (all AEC-Q100 qualified).
• For compact designs: LP5522TM/NOPB (6-DSBGA) or APS13568ELJATR (8-SOIC-EP).

Frequently Asked Questions (FAQ)

Q: Can AL5890-20D-13 directly replace AL5890-15D-13 without circuit modification? A: Yes, for applications operating within 7V to 400V supply range. The 20mA output current is backward compatible with 15mA designs. Both parts use identical TO-252 DPAK packaging and share the same operating temperature range. No PCB layout changes are required.

Q: Why do active substitutes have lower maximum supply voltage than the original part? A: High-voltage LED driver ICs (>100V) represent a specialized product category with limited active production. Most modern LED driver designs operate in the 3V to 40V range, reflecting market demand for low-voltage, integrated solutions. Applications requiring >60V operation must use legacy parts or implement external voltage regulation.

Q: Is AL5810D-13 suitable for designs currently using AL5890-15D-13? A: AL5810D-13 is suitable for applications operating within 2.5V to 60V supply range. The reduced maximum voltage (60V vs. 400V) is the primary limitation. If your circuit operates below 60V, AL5810D-13 offers superior features including PWM dimming, internal switching, and active production status. Verify supply voltage requirements before substitution.

Q: What is the impact of package type changes when substituting parts? A: Package changes require PCB layout redesign. AL5890-15D-13 uses TO-252 DPAK (3-pin). Substitutes include 8-SOIC-EP (APS13568ELJATR, NUD4001DR2G), 16-TQFN (MAX16836ATE+), and 6-DSBGA (LP5522TM/NOPB). Each package has different thermal characteristics, pin spacing, and PCB footprint requirements. Thermal performance may differ; verify thermal management for high-current applications.

Q: Are all substitute parts RoHS3 compliant? A: Yes, all listed substitute parts are RoHS3 compliant. The original AL5890-15D-13 is also RoHS3 compliant. All parts meet REACH requirements and carry EAR99 export classification.

Q: Which substitute offers the best long-term availability? A: AL5810D-13, MAX16836ATE+, NUD4001DR2G, and LP5522TM/NOPB all carry active product status. onsemi (NUD4001DR2G) and Texas Instruments (LP5522TM/NOPB) maintain extensive distribution networks. For Diodes Incorporated ecosystem continuity, AL5810D-13 is the manufacturer-recommended choice.

Q: Can I use a higher-current substitute (e.g., NUD4001DR2G at 500mA) in a 15mA design? A: Yes, higher-current parts are backward compatible in constant-current LED driver applications. The IC regulates output current to the design setpoint; excess current capability provides design margin. Verify that dimming control signals (if present) are compatible with your circuit topology.

Q: What is the significance of automotive qualification (AEC-Q100)? A: AEC-Q100 qualification indicates the part meets automotive industry reliability standards for temperature cycling, moisture resistance, and long-term stability. AL5810D-13, MAX16836ATE+, and NUD4001DR2G carry this qualification, making them suitable for automotive lighting, industrial, and harsh-environment applications. Non-qualified parts are acceptable for consumer and standard commercial use.
