MP4652ES-LF-Z Equivalent & Substitute Parts

Part Overview

The MP4652ES-LF-Z is an AC DC offline switcher LED driver IC manufactured by Monolithic Power Systems Inc., designed for single-output applications in backlight and lighting systems. This device features half-bridge topology with PWM dimming capability and operates across a 9V to 30V supply range in a 16-SOIC package.

The MP4652ES-LF-Z carries a "Not For New Designs" product status, indicating it has been superseded or discontinued for new applications. Identifying equivalent and substitute parts is essential for ongoing production support, legacy system maintenance, and design flexibility when the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP4652ES-LF-Z is determined by the following core parameters:

• Device Type: AC DC Offline Switcher with single output
• Supply Voltage Range: 9V to 30V minimum compatibility
• Dimming Capability: PWM or equivalent control method
• Applications: Backlight and lighting systems
• Compliance: ROHS3 compliance and EAR99 classification

Three substitute parts meet these criteria with varying topology and package configurations:

1. MP4653GY-Z (Monolithic Power Systems Inc.) — Same manufacturer, half-bridge topology, expanded temperature range, active product status
2. AL9910SP-13 (Diodes Incorporated) — Buck-Boost topology, wider supply voltage range (15V–500V), compact 8-SO-EP package
3. TPS92074DR (Texas Instruments) — Buck-Boost topology, narrower supply range (11V–18V), 8-SOIC package

Parameter Comparison

Engineering Selection Recommendations

MP4653GY-Z is the primary recommended substitute. It is manufactured by the same company (Monolithic Power Systems Inc.), maintains identical half-bridge topology and supply voltage range (9V–30V), and carries active product status. The expanded operating temperature range (-40°C to 125°C) provides improved thermal performance over the original part. The 20-SOIC package requires PCB layout modification compared to the 16-SOIC original, but electrical compatibility is direct.

AL9910SP-13 offers an alternative for applications requiring extended supply voltage tolerance (15V–500V). The buck-boost topology provides greater flexibility in power conversion scenarios. The 8-SO-EP package is significantly more compact than the original 16-SOIC, reducing board space requirements. This part is suitable for designs where supply voltage may exceed 30V or where space constraints are critical.

TPS92074DR is applicable only for systems with supply voltage constrained to 11V–18V. The buck-boost topology and compact 8-SOIC package offer space efficiency, but the narrower voltage range limits its use to specific applications. Dimming capability is not specified for this part, which may restrict its suitability depending on system requirements.

All three substitutes maintain ROHS3 compliance and EAR99 classification, ensuring regulatory consistency with the original part.

Frequently Asked Questions (FAQ)

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

A: Electrical substitution is direct due to identical supply voltage range, topology, and dimming method. However, the package change from 16-SOIC to 20-SOIC requires PCB footprint redesign. Pin-to-pin compatibility must be verified against detailed datasheets before implementation.

Q: What is the primary advantage of AL9910SP-13 over the original MP4652ES-LF-Z?

A: AL9910SP-13 supports a significantly wider supply voltage range (15V–500V) compared to MP4652ES-LF-Z (9V–30V), enabling use in high-voltage applications. The 8-SO-EP package also provides a 50% reduction in board footprint. The buck-boost topology offers greater power conversion flexibility.

Q: Is TPS92074DR suitable for all MP4652ES-LF-Z applications?

A: No. TPS92074DR operates only within 11V–18V supply range, which is narrower than the original part's 9V–30V range. Applications requiring supply voltages below 11V or above 18V cannot use this substitute. Additionally, dimming capability is not specified, which may be incompatible with PWM-dependent designs.

Q: Why does MP4653GY-Z have a wider operating temperature range than MP4652ES-LF-Z?

A: MP4653GY-Z operates from -40°C to 125°C (junction temperature), while MP4652ES-LF-Z operates from -20°C to 85°C (ambient temperature). The expanded range reflects the active product status and improved thermal design of the newer device. This provides greater reliability margin in extreme temperature environments.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. MP4653GY-Z, AL9910SP-13, and TPS92074DR are all ROHS3 compliant, maintaining regulatory consistency with the original MP4652ES-LF-Z.

Q: What is the impact of topology differences (half-bridge vs. buck-boost) on substitution?

A: Half-bridge topology (MP4652ES-LF-Z and MP4653GY-Z) and buck-boost topology (AL9910SP-13 and TPS92074DR) operate on different power conversion principles. Buck-boost devices offer greater voltage conversion flexibility but may require circuit redesign. Half-bridge substitutes maintain closer electrical equivalence with the original design.
