AL5890-10Y-13 Equivalent & Substitute Parts

Part Overview

The AL5890-10Y-13 is a linear LED driver IC manufactured by Diodes Incorporated, designed for single-output lighting and signage applications. This device operates as a 1-channel constant-current driver with a 10mA output capability in a compact SOT-89-3 surface-mount package. The part is classified as obsolete, making equivalent and substitute parts necessary for new designs and production continuity. Substitute parts must maintain compatibility with the original electrical specifications while accommodating modern active product alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the AL5890-10Y-13 is determined by the following critical parameters:

• Single Output Configuration: All substitutes must provide 1-channel LED driver functionality
• Linear Topology: Substitutes maintain linear driver architecture
• Supply Voltage Range: Substitutes must operate within or exceed the 7V–400V input range
• Output Current Capability: Substitutes must support at least 10mA output current
• Surface Mount Packaging: All substitutes use surface-mount technology (SOT-89-3, SOIC, TQFN, or SSOP variants)
• RoHS3 Compliance: All substitutes maintain RoHS3 compliance for regulatory alignment
• Operating Temperature: Substitutes must support the -40°C to 105°C minimum range

Substitute parts are grouped by output current capability and supply voltage characteristics. Higher current-rated devices (65mA–360mA) provide design flexibility for future scaling, while maintaining backward compatibility with the original 10mA specification through current-limiting design practices.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility)

BCR402UE6433HTMA1 and MAX16815ASA+ are recommended as primary substitutes. Both are active products with AEC-Q101 and AEC-Q100 automotive qualifications respectively, ensuring long-term availability and supply chain stability. These devices support the required 10mA output current specification and operate within acceptable supply voltage ranges for most lighting applications. The BCR402 offers the lowest minimum supply voltage (1.4V), providing flexibility in low-voltage designs, while the MAX16815 maintains a 6.5V minimum suitable for standard LED driver circuits.

Secondary Substitutes (Extended Current Capability)

IS32LT3175P-GRLA3-TR, MAX16836ATE+T, NUD4011DR2G, and TLD1120ELXUMA1 provide higher output current ratings (70mA–360mA) and are suitable for applications requiring current scaling or multi-LED configurations. These parts maintain RoHS3 compliance and active product status. The TLD1120 and MAX16836 offer extended temperature ranges (-40°C to 150°C and -40°C to 125°C respectively), supporting automotive-grade thermal requirements.

Compliance Considerations

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original AL5890-10Y-13. Automotive-qualified variants (BCR402, IS32LT3175, MAX16836, NUD4011, TLD1120) are preferred for mission-critical applications requiring AEC-Q100 or AEC-Q101 certification.

Frequently Asked Questions (FAQ)

Q: Can the AL5890-10Y-13 be directly replaced with any of these substitutes without circuit modification?

A: Direct pin-for-pin replacement is not possible due to package differences (SOT-89-3 vs. SOIC, TQFN, SSOP). However, all substitutes maintain the same functional topology (single-output linear LED driver) and can be integrated with appropriate PCB layout adjustments. Current-limiting resistor values may require recalculation based on the substitute part's specifications.

Q: Which substitute is best for low-voltage applications below 7V?

A: The BCR402UE6433HTMA1 supports a minimum supply voltage of 1.4V, making it suitable for low-voltage designs. The IS32LT3175P-GRLA3-TR operates from 5V, also accommodating sub-7V applications. Both are active products with automotive qualification.

Q: Are all substitutes suitable for high-temperature environments?

A: The TLD1120ELXUMA1 and BCR402UE6433HTMA1 support operating temperatures up to 150°C (junction temperature), exceeding the original part's 105°C maximum. Other substitutes operate to 125°C. Selection depends on specific thermal requirements.

Q: What is the difference between PWM dimming and no dimming in these LED drivers?

A: The AL5890-10Y-13 provides fixed-current output without dimming capability. Substitutes with PWM dimming (IS32LT3175, MAX16815, MAX16836, NUD4011) enable brightness control through pulse-width modulation. Non-dimming substitutes (BCR402, TLD1120) maintain fixed-current operation similar to the original part.

Q: Which substitute offers the highest output current capability?

A: The MAX16836ATE+T and TLD1120ELXUMA1 provide the highest output current ratings at 350mA and 360mA respectively, suitable for high-brightness LED applications or multi-LED configurations.

Q: Are these substitutes available in the same package as the AL5890-10Y-13?

A: No. The AL5890-10Y-13 uses SOT-89-3 packaging. Substitutes use SOIC, TQFN, SSOP, or SC-74 packages. PCB redesign is required for package migration.

Q: What is the MSL (Moisture Sensitivity Level) consideration for these substitutes?

A: The AL5890-10Y-13 has MSL 1 (unlimited shelf life). Most substitutes maintain MSL 1 (BCR402, MAX16815, MAX16836), while IS32LT3175, NUD4011, and TLD1120 have MSL 3 (168-hour limit), requiring controlled storage conditions.
