AL5890-15P1-13 Equivalent & Substitute Parts

Part Overview

The AL5890-15P1-13 is a linear LED driver IC manufactured by Diodes Incorporated, designed for single-output lighting and signage applications. This device operates as a 15mA constant current source with a supply voltage range of 7V to 400V and does not include PWM dimming capability. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AL5890-15P1-13 is determined by the following critical parameters:

Primary Substitution Criteria:

• Output current capability (15mA nominal)
• Supply voltage operating range (minimum 7V, maximum 400V preferred)
• Linear topology without PWM dimming
• Single output configuration
• PowerDI™ 123 package compatibility
• Surface mount mounting type

Secondary Compatibility Factors:

• Operating temperature range (-40°C minimum, 105°C minimum)
• RoHS3 compliance
• Internal switch configuration (no internal switch preferred for direct replacement)
• Applications in lighting and signage

Substitute parts are grouped into two categories: direct functional equivalents (same current rating and package) and parametric equivalents (different current ratings or enhanced features within the same family).

Parameter Comparison

Engineering Selection Recommendations

Recommended Primary Substitute: AL5809-15P1-7

The AL5809-15P1-7 is the manufacturer-recommended substitute. It maintains the same 15mA output current and PowerDI™ 123 package as the AL5890-15P1-13. Key advantages include active product status, extended operating temperature range (-40°C to 125°C), and lower minimum supply voltage (2.5V). The addition of PWM dimming capability and internal switch does not preclude use in non-dimming applications. Packaging is Tape & Reel (TR) format.

Alternative Parametric Equivalent: AL5890-20P1-13

The AL5890-20P1-13 provides identical package and supply voltage characteristics but with 20mA output current. This part is suitable only where the higher current rating is acceptable within the circuit design. Product status is obsolete.

Cross-Manufacturer Options: IS31LT3172-GRLS4-TR and TSCR420CX6 RFG

These parts represent cross-manufacturer alternatives with different packages and current ratings. IS31LT3172-GRLS4-TR offers 200mA capability in an 8-SOIC-EP package, suitable for higher-power applications. TSCR420CX6 RFG provides 11mA in SOT-23-6 package with automotive-grade qualification. Both require circuit redesign due to package incompatibility.

Compliance Verification

All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original part's regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can AL5809-15P1-7 directly replace AL5890-15P1-13 without circuit modification?

A: The AL5809-15P1-7 shares the same output current (15mA) and PowerDI™ 123 package, enabling direct pin-compatible substitution. The addition of PWM dimming and internal switch functionality does not prevent operation in fixed-current applications. However, verify that the lower minimum supply voltage (2.5V vs. 7V) and reduced maximum supply voltage (60V vs. 400V) are compatible with your circuit design.

Q: Why is AL5890-20P1-13 listed as a substitute if the current rating differs?

A: AL5890-20P1-13 is classified as a parametric equivalent rather than a direct replacement. It maintains identical package, supply voltage range, and topology but delivers 20mA instead of 15mA. Use this part only if the circuit design accommodates the higher current output.

Q: What are the package implications of using IS31LT3172-GRLS4-TR or TSCR420CX6 RFG?

A: Both parts require PCB redesign due to different package formats. IS31LT3172-GRLS4-TR uses 8-SOIC-EP (0.154" width) versus PowerDI™ 123. TSCR420CX6 RFG uses SOT-23-6. Pin configurations and thermal characteristics differ, necessitating full circuit validation.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the AL5890-15P1-13.

Q: Which substitute has the widest operating temperature range?

A: TSCR420CX6 RFG operates from -55°C to 150°C (junction temperature), providing the broadest temperature coverage. AL5809-15P1-7 and IS31LT3172-GRLS4-TR both support -40°C to 125°C.

Q: Is AL5809-15P1-7 available in higher quantities?

A: AL5809-15P1-7 is listed as active product status with 1158 pieces in stock. The original AL5890-15P1-13 is obsolete with 5325 pieces available. Verify current inventory with your supplier for production requirements.
