Replacement verdict
Compatible functional replacement candidate
The APDS-9250 is a viable functional replacement candidate for the APDS-9306-065 in ambient light sensing applications, sharing the same I²C digital interface, similar supply voltage range, and comparable package footprint. However, the APDS-9250 integrates an additional IR channel and offers a wider dynamic range, so firmware configuration and register mapping must be validated before substitution. Designers should confirm spectral response requirements and re-verify I²C address and timing parameters during qualification.

Key electrical and mechanical differences between the two devices
| Parameter | APDS-9306-065 | APDS-9250 | Why it matters |
|---|---|---|---|
| Sensor Type / Function | Ambient light sensor (ALS) only | Digital RGB, IR + ambient light sensor | Determines whether the part can provide color/IR sensing or only illuminance, which affects functional substitutability in a design. |
| Output Interface | I2C (up to 400 kHz) | I2C (up to 400 kHz) | Both use I2C, but register maps and command sets differ, so firmware compatibility must be checked. |
| Supply Voltage Range | 1.7 V to 3.6 V | 1.7 V to 3.6 V | Identical supply range allows drop-in use on the same power rail without level shifting. |
| Number of Channels / Spectral Bands | Single ALS channel (with IR rejection) | Four channels (Red, Green, Blue, IR) plus ALS | Channel count defines the sensing capability; a single-channel ALS cannot replace a multi-channel RGB/IR sensor for color or IR applications. |
| Package / Footprint | 6-pin ODFN (2.0 mm x 2.0 mm) | 8-pin ODFN (2.0 mm x 2.0 mm) | Different pin counts and pad layouts mean the parts are not footprint-compatible and require PCB redesign. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Matching temperature ranges ensure equivalent environmental robustness for industrial and consumer applications. |
| Resolution / ADC Bits | Up to 20-bit ALS resolution | Up to 20-bit per channel | High resolution enables accurate lux measurement across wide dynamic range; comparable resolution supports similar light-measurement performance. |
| Interrupt / Threshold Support | Programmable interrupt with upper/lower thresholds | Programmable interrupt with upper/lower thresholds | Interrupt capability allows event-driven operation and reduces host polling, important for low-power system design. |

Frequently asked questions
What are the key differences between the APDS-9306-065 and APDS-9250 ambient light sensors?
The APDS-9306-065 is a digital ambient light sensor with an I²C interface and a fixed I²C address, supplied in a 6-pin ODFN package measuring 2.0 × 2.0 × 0.65 mm. The APDS-9250 is a digital RGB, ambient light, and IR sensor with an I²C interface, supplied in an 8-pin ODFN package. The APDS-9250 provides color (RGB) and IR sensing channels in addition to ambient light, while the APDS-9306-065 provides ambient light sensing only.
Do the APDS-9306-065 and APDS-9250 use the same I²C interface and supply voltage?
Both devices use an I²C digital interface and operate from a nominal 1.8 V supply (VDD range of 1.7 V to 2.0 V per Broadcom datasheets). The APDS-9250 additionally provides a separate VDDIO pin for I/O level shifting, whereas the APDS-9306-065 integrates the I²C I/O supply internally. Designers should confirm the exact supply and I/O voltage requirements against the respective datasheets before layout.
Can the APDS-9306-065 be used as a drop-in replacement for the APDS-9250?
No. The two devices differ in package pin count and footprint (6-pin vs 8-pin ODFN), I²C address configuration, and register maps. The APDS-9250 also provides RGB and IR channels that the APDS-9306-065 does not. A direct drop-in replacement is not possible; a redesign of the PCB land pattern and firmware register access would be required.
Which sensor is better suited for color or RGB sensing applications?
The APDS-9250 is the appropriate choice for color or RGB sensing because it integrates red, green, blue, and IR photodiode channels in addition to ambient light sensing. The APDS-9306-065 provides ambient light (clear channel) sensing only and does not offer color discrimination.
How do the package footprints of the APDS-9306-065 and APDS-9250 compare?
The APDS-9306-065 is housed in a 6-pin ODFN package with a 2.0 × 2.0 mm footprint and 0.65 mm height. The APDS-9250 is housed in an 8-pin ODFN package. Because the pin counts and land patterns differ, the two devices are not footprint-compatible and require separate PCB layouts.
Do both sensors support interrupt output for threshold-based wake-up?
Yes. Both the APDS-9306-065 and APDS-9250 provide a programmable interrupt output that can be configured with high and low threshold registers to signal ambient light level changes to a host processor. The specific register settings and interrupt persistence options should be verified in each device's datasheet.
Which device offers a wider dynamic range for ambient light measurement?
Both devices are designed for high-sensitivity ambient light measurement with programmable gain and integration time settings. The APDS-9306-065 is specified for operation up to approximately 100 klux, and the APDS-9250 is similarly specified for high-lux ambient light sensing. Exact dynamic range, resolution, and gain settings should be confirmed from the respective Broadcom datasheets for the target design conditions.
