Substitute Part Grouping Explanation
Substitution for the AL5890-30Y-13 is determined by the following critical parameters:
- Single Output Configuration: All substitute parts must provide exactly one output channel
- Linear Driver Topology: Substitute parts must operate as linear LED drivers
- Output Current Capability: Substitute parts must support the required 30mA output current or higher
- Supply Voltage Range: Substitute parts must accommodate the operating voltage requirements
- Surface Mount Packaging: All substitutes use surface mount technology
- Compliance Standards: All substitutes maintain ROHS3 compliance and REACH unaffected status
The substitute parts listed below meet these core substitution criteria. Note that some substitutes introduce PWM dimming capability and higher current ratings, which represent functional enhancements rather than deviations from the core LED driver function.

Engineering Selection Recommendations
MAX16836ASA+ (Recommended Primary Substitute)
The MAX16836ASA+ from Analog Devices Inc./Maxim Integrated is the preferred substitute for the AL5890-30Y-13. This part maintains active product status, ensuring long-term availability and supply chain stability. It provides 350mA output current capability, exceeding the original 30mA requirement, and operates across a 6.5V to 40V supply range. The device includes PWM dimming functionality and internal switching capability. Operating temperature range extends to 125°C (TJ), and the part carries automotive-grade qualification, providing enhanced reliability for critical applications. ROHS3 compliance and REACH unaffected status are maintained.
STCS1APUR (Alternative for High Current Applications)
The STCS1APUR from STMicroelectronics offers the highest output current capability at 1.5A, suitable for applications requiring current headroom beyond the original specification. This part operates across 4.5V to 40V supply range and maintains active product status. Operating temperature extends to 150°C (TJ). This substitute is appropriate when design margins or future current scaling are considerations.
TLD1211SJFUMA1 (Automotive-Grade Alternative)
The TLD1211SJFUMA1 from Infineon Technologies provides automotive-grade qualification with 85mA output current capability. Operating temperature range reaches 150°C (TJ), and the part maintains active product status. This substitute is suitable for automotive lighting and signage applications requiring enhanced environmental performance.
BCR450E6327HTSA1 (Limited Availability)
The BCR450E6327HTSA1 from Infineon Technologies carries Last Time Buy status, indicating limited future availability. While it provides 85mA output current and PWM dimming capability, procurement should prioritize active-status alternatives for new designs.
TLE4241GMXUMA1 (Compact Supply Range)
The TLE4241GMXUMA1 from Infineon Technologies supports the widest minimum supply voltage at 4V, extending to 45V maximum. Output current capability is 60mA. This part maintains active product status and is suitable for low-voltage input applications.
Frequently Asked Questions (FAQ)
Q: Can the AL5890-30Y-13 be directly replaced with any of these substitutes without circuit modification?
A: Direct pin-for-pin replacement is not guaranteed due to package differences and functional enhancements in substitute parts. The AL5890-30Y-13 uses SOT-89-3 packaging, while substitutes employ various packages including SC-74, 8-SOIC, 8-DFN, and 8-DSO. Circuit evaluation and layout redesign may be required. Consult device datasheets for pinout and functional compatibility.
Q: Why do all substitute parts include PWM dimming when the original AL5890-30Y-13 does not?
A: The substitute parts represent current-generation LED driver technology. PWM dimming capability is a standard feature in modern linear LED drivers and does not prevent operation in non-dimming applications. PWM inputs can be held at fixed logic levels to disable dimming functionality.
Q: Which substitute is best for high-temperature applications?
A: The STCS1APUR, TLD1211SJFUMA1, and TLE4241GMXUMA1 all support operating temperatures to 150°C (TJ), compared to the original part's 105°C (TA) rating. The STCS1APUR offers the highest current capability at this temperature range.
Q: Is the MAX16836ASA+ suitable for automotive applications?
A: Yes. The MAX16836ASA+ carries automotive-grade qualification and operates across -40°C to 125°C (TJ). This part is appropriate for automotive lighting and signage applications.
Q: What is the significance of "Last Time Buy" status for the BCR450E6327HTSA1?
A: Last Time Buy status indicates that the manufacturer has announced end-of-life for this part. While current inventory may be available, future procurement will not be possible. For new designs, select from parts with Active product status: MAX16836ASA+, STCS1APUR, TLD1211SJFUMA1, or TLE4241GMXUMA1.
Q: Can I use a substitute with higher output current rating in place of the AL5890-30Y-13?
A: Yes. Higher current-rated substitutes (BCR450E6327HTSA1 at 85mA, MAX16836ASA+ at 350mA, STCS1APUR at 1.5A, TLD1211SJFUMA1 at 85mA, TLE4241GMXUMA1 at 60mA) are backward-compatible with 30mA load requirements. The driver will operate at the required current level without degradation. Verify that thermal management and PCB layout accommodate the selected device.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the environmental compliance profile of the original AL5890-30Y-13.
