AL9902S16-13 Equivalent & Substitute Parts

Part Overview

The AL9902S16-13 is an LED Driver IC manufactured by Diodes Incorporated, classified as a Power Management (PMIC) component. This device functions as a 1-output AC DC offline switcher with step-down (buck) and step-up (boost) topology, supporting analog and PWM dimming at 400mA output current. The part is actively produced and stocked with 1119 units available. Alternative components may be required due to supply constraints, design optimization, or application-specific requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AL9902S16-13 are identified based on the following critical parameters that determine functional compatibility:

• AC DC offline switcher topology with single output configuration
• Supply voltage range capability (minimum 20V, maximum 450V or higher)
• LED driver application suitability (backlight, lighting, signage)
• Surface mount packaging in SOIC form factor
• PWM dimming support
• Operating temperature range of -40°C or lower to 85°C or higher
• ROHS3 compliance and active product status

The substitute parts listed maintain core functionality as LED driver ICs with offline switcher topology, though individual specifications may vary in output current, frequency, dimming method, and package pin count.

Parameter Comparison

Engineering Selection Recommendations

All three components maintain active product status and ROHS3 compliance, meeting regulatory requirements for new designs. Selection between the AL9902S16-13 and its substitutes depends on specific application constraints:

The AL9902S16-13 provides the highest supply voltage maximum (500V) and supports both analog and PWM dimming methods within a 16-pin package. This configuration suits applications requiring wide input voltage range and flexible dimming control.

The MXHV9910BE operates within a lower supply voltage range (8V to 450V) with PWM-only dimming in an 8-pin package with exposed pad. This option is suitable for applications with constrained board space and lower voltage requirements.

The TPS92075DR/NOPB supports the widest operating temperature range (-40°C to 125°C junction temperature) and features triac dimming capability in an 8-pin package. This part is applicable to lighting applications requiring triac-based dimming control and extended thermal performance.

Frequently Asked Questions (FAQ)

Q: Can MXHV9910BE directly replace AL9902S16-13 in existing designs?

A: Direct replacement requires design verification. The MXHV9910BE operates at lower maximum supply voltage (450V vs 500V), uses an 8-pin package versus 16-pin, and supports PWM dimming only. PCB layout modifications and firmware adjustments may be necessary.

Q: What are the key differences in dimming capability between these parts?

A: The AL9902S16-13 supports both analog and PWM dimming. The MXHV9910BE supports PWM dimming only. The TPS92075DR/NOPB uses triac dimming, which is fundamentally different and requires different circuit implementation for phase-cut dimming control.

Q: Which substitute is suitable for high-temperature applications?

A: The TPS92075DR/NOPB offers the highest operating temperature rating at -40°C to 125°C (junction temperature), compared to AL9902S16-13 at -40°C to 105°C (ambient temperature) and MXHV9910BE at -40°C to 85°C (ambient temperature).

Q: Are package differences significant for PCB redesign?

A: Yes. The AL9902S16-13 uses 16-SOIC packaging, while both substitutes use 8-SOIC packaging. This requires PCB layout changes, different pin assignments, and potential modifications to supporting circuitry. The MXHV9910BE includes an exposed pad for thermal management, which may require additional PCB design considerations.

Q: What supply voltage range is common across all three parts?

A: The overlapping supply voltage range is 20V to 450V. Applications requiring operation above 450V are limited to the AL9902S16-13. Applications below 20V may use MXHV9910BE (down to 8V) or TPS92075DR/NOPB (down to 11V).
