Key Parameters

Substitute Part Grouping Explanation

Substitution for the AL5890-20P1-13 is determined by the following critical parameters:

• Output Current: 20mA nominal rating
• Package Type: POWERDI®123 form factor
• Supply Voltage Range: Minimum 7V to maximum 400V
• Dimming Capability: No dimming required
• Mounting: Surface mount configuration
• Compliance: ROHS3 compliant

Substitute parts are grouped into two categories:

Category 1 - Parametric Equivalent (Same Base Specifications) Parts maintaining identical supply voltage range (7V–400V), same package (POWERDI®123), and no dimming functionality, with current output variations acceptable for the application.

Category 2 - Functional Equivalent (Different Specifications) Parts with different supply voltage ranges, package types, or enhanced features (such as dimming capability) that may serve the same application but require design verification for compatibility.

Parameter Comparison

Engineering Selection Recommendations

AL5809-20P1-7 (Diodes Incorporated) This part is the primary recommended substitute. It maintains the same 20mA output current and POWERDI®123 package as the AL5890-20P1-13. The AL5809-20P1-7 is active in production with extended temperature range (-40°C to 125°C) and includes PWM dimming capability. The reduced supply voltage range (2.5V–60V) requires verification against the original 7V–400V specification. This part is suitable for applications where the lower maximum voltage is acceptable.

AL5890-30P1-13 (Diodes Incorporated) This parametric equivalent maintains the same supply voltage range (7V–400V) and POWERDI®123 package. The primary difference is the increased output current of 30mA versus 20mA. This part is obsolete, similar to the original. Selection requires confirmation that the higher current output does not exceed circuit requirements.

BCR402UE6433HTMA1 (Infineon Technologies) This part offers an active production status with automotive-grade qualification (AEC-Q101). It features constant current topology with 65mA output and operates across 1.4V–40V supply range. The package differs (SC-74, SOT-457 versus POWERDI®123), requiring PCB layout redesign. The significantly higher output current and lower supply voltage range necessitate comprehensive design verification.

CL6K4-G (Microchip Technology) This active part provides 100mA output current with PWM dimming in a TO-252 (DPAK) package. The supply voltage range (6.5V–90V) is closer to the original specification than other alternatives. The package change from POWERDI®123 to TO-252 requires PCB modification. The higher current output and different package form factor require full design re-evaluation.

Frequently Asked Questions (FAQ)

Q: Can AL5809-20P1-7 directly replace AL5890-20P1-13 in existing designs? A: Direct replacement requires verification of the reduced maximum supply voltage (60V versus 400V). If the application operates within 2.5V–60V, the AL5809-20P1-7 is compatible. The identical 20mA output current and POWERDI®123 package enable pin-for-pin substitution. The addition of PWM dimming capability does not prevent use in non-dimming applications.

Q: What is the primary difference between AL5890-20P1-13 and AL5890-30P1-13? A: Both parts share identical supply voltage range (7V–400V), package type (POWERDI®123), and linear topology. The AL5890-30P1-13 provides 30mA output current compared to 20mA. Selection depends on whether the circuit can accommodate the higher current without exceeding LED or load specifications.

Q: Why do BCR402UE6433HTMA1 and CL6K4-G require design changes? A: Both parts use different package types (SC-74 and TO-252 respectively) compared to the POWERDI®123 package of the original part. Package changes require PCB layout redesign, including trace routing, thermal management, and component placement modifications. Additionally, both parts feature significantly higher output currents (65mA and 100mA), requiring circuit verification to ensure compatibility with existing LED or load specifications.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the environmental and regulatory status of the AL5890-20P1-13.

Q: What is the impact of dimming capability on substitution? A: The AL5890-20P1-13 has no dimming functionality. Substitute parts AL5809-20P1-7, BCR402UE6433HTMA1, and CL6K4-G include dimming capability (PWM or constant current control). In applications where dimming is not required, these features remain inactive and do not affect operation. However, design review is necessary to confirm that additional control pins do not conflict with existing circuit topology.

Q: Which substitute offers the closest match to the original part? A: AL5809-20P1-7 provides the closest functional match, maintaining identical output current (20mA) and package type (POWERDI®123). The primary design consideration is the reduced maximum supply voltage (60V versus 400V). For applications operating within this voltage range, this part enables direct substitution with minimal circuit modification.
