MP4652ES-LF Equivalent & Substitute Parts

Part Overview

The MP4652ES-LF is an LED driver IC manufactured by Monolithic Power Systems Inc., designed for AC DC offline switching applications with half-bridge topology and PWM dimming capability. This component is actively produced and suitable for backlight and lighting applications. Substitute parts may be required due to inventory constraints, design optimization, or application-specific performance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP4652ES-LF are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• AC DC offline switcher topology
• Single output configuration
• Supply voltage range overlap (9V to 30V minimum requirement)
• LED driver application suitability
• Surface mount packaging

Substitute Parts Identified:

1. MP4653GY - Manufacturer recommended substitute with enhanced operating temperature range and dual dimming capability (Analog and PWM)
2. RT8497AGS - Alternative topology (Step-Down Buck) with higher current output specification and internal switch integration

Parameter Comparison

Engineering Selection Recommendations

MP4653GY is the manufacturer-recommended substitute for the MP4652ES-LF. Both parts are manufactured by Monolithic Power Systems Inc. and maintain active product status. The MP4653GY offers an extended operating temperature range (-40°C to 125°C) compared to the MP4652ES-LF (-20°C to 85°C), and provides dual dimming modes (Analog and PWM) versus PWM-only on the original part. The package change from 16-SOIC to 20-SOIC requires PCB layout modification. Both parts are ROHS3 compliant and REACH unaffected.

RT8497AGS is an alternative from Richtek USA Inc. with different topology (Step-Down Buck versus Half-Bridge). This part carries obsolete product status and should be considered only when legacy design compatibility is required. The RT8497AGS features internal switching capability and specified output current of 1.4A, differing fundamentally from the MP4652ES-LF architecture. All three parts maintain ROHS3 compliance and EAR99 ECCN classification.

Frequently Asked Questions (FAQ)

Q: Can MP4653GY directly replace MP4652ES-LF without circuit modification?

A: MP4653GY maintains the same supply voltage range (9V to 30V) and half-bridge topology as MP4652ES-LF. However, the package changes from 16-SOIC to 20-SOIC, requiring PCB layout redesign. The dual dimming capability (Analog and PWM) is backward compatible with PWM-only designs.

Q: What is the significance of the operating temperature difference between MP4652ES-LF and MP4653GY?

A: MP4652ES-LF operates from -20°C to 85°C (TA), while MP4653GY operates from -40°C to 125°C (TJ). The MP4653GY supports extended temperature applications and higher thermal stress environments.

Q: Is RT8497AGS suitable as a direct substitute?

A: RT8497AGS differs in topology (Step-Down Buck versus Half-Bridge) and carries obsolete product status. It is not a direct substitute but may serve alternative designs requiring buck converter topology with integrated switching. The minimum supply voltage is 10V versus 9V for MP4652ES-LF.

Q: What packaging considerations apply to these substitutes?

A: MP4652ES-LF uses 16-SOIC (3.90mm width), MP4653GY uses 20-SOIC (7.50mm width), and RT8497AGS uses 8-SOIC (3.90mm width). Package changes require PCB footprint modification and board layout revision.

Q: Are all three parts RoHS compliant?

A: Yes. MP4652ES-LF, MP4653GY, and RT8497AGS are all ROHS3 compliant and REACH unaffected.
