Key Parameters

Substitute Part Grouping Explanation

Substitution of the AP3064P-G1 is determined by the following critical parameters: DC DC controller topology (Step-Up/Boost), 4-output configuration, input voltage range (4.5V to 33V maximum), PWM dimming capability, and through-hole or surface-mount packaging compatibility. All substitute parts maintain the same functional topology and output channel count. However, substitutes may vary in the following areas: output voltage capability, per-channel current rating, operating temperature range, package form factor, and product status (active vs. obsolete).

The AP3064P-G1 is listed as obsolete; therefore, active alternatives are required for new designs or production restarts. Substitute parts are grouped by their ability to meet the core electrical specifications while offering improved availability and, in some cases, enhanced performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with ROHS3 compliance, ensuring regulatory alignment and long-term availability compared to the obsolete AP3064P-G1.

IS32BL3554-ZLA3-TR offers the closest electrical match with identical input voltage range (4.5V to 33V) and frequency specification (100kHz ~ 1MHz). This part includes AEC-Q100 automotive qualification and extends operating temperature to 125°C. The trade-off is reduced per-channel current (180mA vs. 220mA) and lower output voltage (50V vs. 60V). Surface-mount 16-TSSOP packaging requires PCB redesign from the through-hole DIP format.

MP3385AGR-P provides enhanced per-channel current capability (300mA) and higher output voltage (80V), supporting more demanding LED backlight configurations. Extended operating temperature (125°C) and multiple dimming modes (Analog, I2C, PWM) offer design flexibility. The 20-QFN package requires surface-mount assembly and PCB layout modification.

MP3398AGY-Z delivers the highest per-channel current (350mA) and supports both analog and PWM dimming. Operating temperature extends to 125°C. Input voltage maximum is reduced to 28V, which may limit applicability in designs requiring the full 33V input range. The 20-SOIC package is surface-mount and requires board redesign.

MP3398EGF-Z provides a compact 16-TSSOP surface-mount alternative with minimal specification data provided. This part is available in high inventory (18,964 pcs) and maintains the 16-pin package footprint, though through-hole compatibility is not preserved.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the AP3064P-G1 with any of these substitutes without PCB modification?

A: No. The AP3064P-G1 uses through-hole 16-DIP packaging, while all substitutes employ surface-mount technology (TSSOP, QFN, or SOIC). PCB redesign is required for any substitution.

Q: Which substitute best preserves the original electrical specifications?

A: IS32BL3554-ZLA3-TR maintains the closest match: identical input voltage range (4.5V to 33V), same frequency band (100kHz ~ 1MHz), and 4-output configuration. Per-channel current is reduced from 220mA to 180mA, and output voltage decreases from 60V to 50V.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitutes are ROHS3 compliant, matching the original part's regulatory status.

Q: What is the key difference between MP3385AGR-P and MP3398AGY-Z?

A: MP3385AGR-P supports three dimming modes (Analog, I2C, PWM) with 300mA per-channel current and 80V output voltage. MP3398AGY-Z supports two dimming modes (Analog, PWM) with higher per-channel current (350mA) but reduced maximum input voltage (28V vs. 33V).

Q: Why does MP3398EGF-Z have incomplete specifications?

A: MP3398EGF-Z is listed with minimal technical data in the provided documentation. Detailed specifications should be obtained from the manufacturer datasheet before design implementation.

Q: Can I use IS32BL3554-ZLA3-TR in automotive applications?

A: Yes. IS32BL3554-ZLA3-TR carries AEC-Q100 automotive qualification, making it suitable for automotive-grade LED backlight systems.

Q: What is the operating temperature advantage of the substitutes?

A: The AP3064P-G1 operates from -40°C to 85°C. IS32BL3554-ZLA3-TR, MP3385AGR-P, and MP3398AGY-Z all extend the upper limit to 125°C, providing improved thermal margin in high-temperature environments.
