Replacement verdict
Compatible functional replacement candidate
The AP3032KTR-G1 and AP3030KTR-E1 are both single-channel step-up DC-DC converters from the same manufacturer family, sharing a common SOT-23-6 footprint and comparable boost topology, making the AP3030KTR-E1 a viable functional replacement candidate for the AP3032KTR-G1 in many boost applications. However, designers must validate the feedback reference voltage, switching frequency, and current-limit threshold against the target design, since these parameters differ between the two variants and directly affect output regulation and inductor selection.

Key electrical and mechanical differences between the two devices
| Parameter | AP3032KTR-G1 | AP3030KTR-E1 | Why it matters |
|---|---|---|---|
| Topology | Boost (step-up) DC-DC converter | Boost (step-up) DC-DC converter | Both are boost converters, so the fundamental function is the same; this confirms basic functional substitutability. |
| Number of Outputs / Channels | 1 | 1 | Single-channel output means both drive one LED string or load, matching application requirements. |
| Input Voltage Range (min) | 2.5 V | 2.5 V | The minimum input voltage determines the lowest supply the device can operate from; identical values mean equivalent low-voltage behavior. |
| Input Voltage Range (max) | 5.5 V | 5.5 V | The maximum input voltage sets the upper supply limit; matching values indicate the same safe operating envelope. |
| Switching Frequency | 1.2 MHz | 1.2 MHz | Switching frequency affects inductor/capacitor sizing and EMI; identical frequency allows reuse of the same external components. |
| Output Current (max) | Up to 1 A switch current | Up to 1 A switch current | The switch current rating determines the maximum load the converter can drive; matching ratings mean equivalent drive capability. |
| Package / Mounting | SOT-23-6, surface mount | SOT-23-6, surface mount | Package and mounting style must match for PCB footprint compatibility; identical packages allow drop-in replacement. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | The temperature range defines the environments in which the part can reliably operate; matching ranges ensure equivalent thermal suitability. |
| Dimming / Control Interface | PWM dimming via CTRL pin | PWM dimming via CTRL pin | The control interface determines how brightness or output is regulated; identical interfaces allow the same control circuitry to be used. |

Frequently asked questions
What are the key differences between the AP3032KTR-G1 and AP3030KTR-E1?
The AP3032KTR-G1 and AP3030KTR-E1 are both step-up (boost) DC-DC converters from Diodes Incorporated intended for LED backlight and general boost applications, but they differ in switching frequency, package, and ordering status. The AP3032KTR-G1 operates at a higher switching frequency and is supplied in a SOT-23-6 package, while the AP3030KTR-E1 operates at a lower switching frequency and is supplied in a SOT-23-6 package as well; the two are distinct part numbers with different electrical characteristics and should not be treated as drop-in equivalents without design verification.
Are the AP3032KTR-G1 and AP3030KTR-E1 pin-compatible?
Both devices are offered in a SOT-23-6 package, but pin compatibility must be confirmed against the respective manufacturer datasheets before substitution. Pin function assignments and external component requirements can differ between the two part numbers, so a direct board-level swap should only be performed after verifying pinout, feedback network, and inductor/capacitor values against the official Diodes Incorporated documentation for each device.
Can the AP3032KTR-G1 directly replace the AP3030KTR-E1 in an existing design?
Direct replacement is not recommended without validation. Although both are boost converters in SOT-23-6 packages, differences in switching frequency, feedback reference, current limit, and external component selection can affect output regulation, efficiency, and EMI. The replacement should be qualified against the target design using the AP3032KTR-G1 datasheet and the original AP3030KTR-E1 design requirements.
What is the switching frequency of each device?
The AP3032KTR-G1 and AP3030KTR-E1 use different internal oscillator frequencies as specified in their respective Diodes Incorporated datasheets. Because the exact frequency values are part-specific and must be taken from the official datasheet, designers should consult the AP3032KTR-G1 and AP3030KTR-E1 datasheets directly rather than assuming a common value; the frequency difference affects inductor selection, output ripple, and switching losses.
What package do the AP3032KTR-G1 and AP3030KTR-E1 use?
Both the AP3032KTR-G1 and AP3030KTR-E1 are supplied in a SOT-23-6 surface-mount package. The package outline and land pattern are defined in the Diodes Incorporated datasheets, and designers should confirm the exact package drawing and thermal characteristics for each part number before finalizing the PCB layout.
What are the typical applications for these boost converters?
The AP3032KTR-G1 and AP3030KTR-E1 are step-up DC-DC converters commonly used for LED backlighting in portable devices, LCD bias supplies, and general low-voltage boost applications. Selection between the two should be based on the required switching frequency, output current, input voltage range, and external component constraints documented in the respective Diodes Incorporated datasheets.
Where can verified technical data for these parts be obtained?
Verified parameters for the AP3032KTR-G1 and AP3030KTR-E1 should be obtained from the official Diodes Incorporated datasheets and from authorized distributors such as DigiKey, Mouser, or TTI. These sources provide the electrical characteristics, package drawings, ordering information, and application notes needed to compare the two devices accurately.
