Key Parameters

Substitute Part Grouping Explanation

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

• Type: Linear LED driver topology
• Number of Outputs: Single output configuration
• Supply Voltage Range: Minimum 7V to maximum 400V (or compatible subset)
• Output Current: 15mA nominal (substitutes may have higher current ratings)
• Dimming Capability: No dimming required for basic compatibility
• Mounting Type: Surface mount
• RoHS Compliance: ROHS3 Compliant
• Operating Temperature Range: -40°C minimum to 105°C minimum

The substitute parts identified (APS13568KLJATR, CL7SG-G, IS32LT3175P-GRLA3-TR, STCS05DR) are all linear, single-output LED driver ICs in surface mount packages with ROHS3 compliance. These parts differ in supply voltage ranges, output current capabilities, dimming features, and package types, but maintain functional equivalence for LED driver applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with ROHS3 compliance, ensuring regulatory alignment and production availability. Selection among these substitutes depends on application-specific requirements:

APS13568KLJATR (Allegro MicroSystems): Active status with automotive-grade qualification (AEC-Q100). Supply voltage range 7V–24V matches the AL5890-15Y-13 minimum requirement. Output current of 150mA exceeds the original 15mA specification. Includes PWM dimming and internal switch. 8-SOIC-EP package requires PCB layout adjustment from the original SOT-89-3.

CL7SG-G (Microchip Technology): Active status with supply voltage range 6.5V–90V, providing broader high-voltage capability than the AL5890-15Y-13. Output current of 100mA exceeds original specification. Includes PWM dimming. MSL rating of 1 (Unlimited) matches the original part. 8-SOIC package requires layout modification.

IS32LT3175P-GRLA3-TR (Lumissil Microsystems): Active status with automotive-grade qualification (AEC-Q100). Supply voltage range 5V–42V. Output current of 150mA exceeds original specification. Includes PWM dimming and internal switch. 8-SOIC package requires layout adjustment.

STCS05DR (STMicroelectronics): Active status with the widest operating temperature range (-40°C to 150°C). Supply voltage range 4.5V–40V. Output current of 500mA significantly exceeds original specification. Includes PWM dimming and internal switch. MSL rating of 1 (Unlimited) matches the original part. 8-SOIC package requires layout modification.

Frequently Asked Questions (FAQ)

Q: Can I directly replace AL5890-15Y-13 with any of these substitute parts?

A: Direct replacement requires verification of supply voltage range compatibility with your application. The AL5890-15Y-13 operates at 7V–400V; substitute parts have lower maximum voltage ratings (24V–90V). If your application requires the full 400V range, none of these substitutes are compatible. For applications within the substitute voltage ranges, PCB layout modifications are necessary due to package differences (SOT-89-3 vs. 8-SOIC).

Q: What is the main difference between the AL5890-15Y-13 and the substitute parts?

A: The primary differences are: (1) Product status—the original is obsolete while all substitutes are active; (2) Supply voltage maximum—the original supports up to 400V while substitutes support 24V–90V; (3) Dimming capability—the original has no dimming while all substitutes include PWM dimming; (4) Output current—substitutes provide 100mA–500mA versus the original 15mA; (5) Package type—substitutes use 8-SOIC variants instead of SOT-89-3.

Q: Which substitute part is best for high-voltage applications?

A: CL7SG-G supports the highest supply voltage among substitutes at 90V maximum, though this remains significantly below the AL5890-15Y-13's 400V capability. If your application requires operation above 90V, none of these substitutes are suitable.

Q: Do all substitute parts require PCB layout changes?

A: Yes. The AL5890-15Y-13 uses a SOT-89-3 package, while all substitute parts use 8-SOIC or 8-SOP variants. These packages have different pin configurations, spacing, and footprints, requiring PCB redesign and re-layout.

Q: Are automotive-qualified versions available?

A: Yes. APS13568KLJATR and IS32LT3175P-GRLA3-TR both carry AEC-Q100 automotive qualification. These parts are suitable for automotive lighting and signage applications.

Q: What is the moisture sensitivity difference between parts?

A: AL5890-15Y-13 and CL7SG-G have MSL 1 (Unlimited), meaning no moisture sensitivity restrictions. APS13568KLJATR and IS32LT3175P-GRLA3-TR have MSL 3 (168 Hours), requiring controlled storage and handling within 168 hours of package opening. STCS05DR has MSL 1 (Unlimited).

Q: Can I use a substitute with higher output current than the original 15mA?

A: Yes, if your LED load and circuit design accommodate the higher current capability. Higher current-rated drivers (100mA–500mA) can operate at lower currents without performance degradation. Verify that your current-limiting resistors and LED specifications are compatible with the substitute part's characteristics.
