Key Parameters

Substitute Part Grouping Explanation

Substitution of the APDS-9901 is determined by the following critical parameters:

• Optical Detection Capability: Ambient light sensing with proximity detection functionality
• Communication Protocol: I2C interface compatibility
• Wavelength Range: Optical response in the visible spectrum (640nm primary)
• Supply Voltage Compatibility: Operating range overlap with 2.5V ~ 3.6V
• Package Type: Surface mount configuration with compatible pinout
• Environmental Specifications: Operating temperature range and moisture sensitivity classification
• Compliance Standards: ROHS3 compliance and REACH status

The APDS-9930 qualifies as a direct substitute based on these parameters. Both components are manufactured by Broadcom Limited, feature I2C output, support proximity detection, operate within compatible voltage ranges, and maintain equivalent environmental and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The APDS-9930 is the designated substitute for the APDS-9901. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for applications requiring these certifications. The APDS-9930 provides an extended lower supply voltage limit (2.2V versus 2.5V) and expanded operating temperature range (-40°C versus -30°C minimum), offering broader environmental compatibility. The wavelength difference (625nm versus 640nm) remains within the visible spectrum and does not preclude functional equivalence for ambient light sensing applications. Both components are classified as obsolete; component selection should prioritize availability and long-term supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can the APDS-9930 directly replace the APDS-9901 in existing designs?

A: Yes. Both components share identical I2C communication protocol, proximity detection capability, and equivalent electrical specifications. The package designation differs (8-SMD Module versus 8-SMD, No Lead); PCB layout compatibility must be verified against the specific module configuration.

Q: What is the significance of the wavelength difference between 640nm and 625nm?

A: Both wavelengths operate within the visible red spectrum and are suitable for ambient light detection. The wavelength difference reflects sensor design variations between product generations but does not prevent functional substitution for standard ambient sensing applications.

Q: Are there supply voltage compatibility concerns?

A: The APDS-9930 operates at 2.2V ~ 3.6V, providing a lower minimum threshold than the APDS-9901 (2.5V ~ 3.6V). Designs operating at 2.2V ~ 2.5V can utilize the APDS-9930 exclusively. Both components function across the overlapping 2.5V ~ 3.6V range.

Q: How do the operating temperature ranges compare?

A: The APDS-9930 supports -40°C ~ 85°C, extending the lower temperature limit by 10°C compared to the APDS-9901 (-30°C ~ 85°C). Applications requiring operation below -30°C must use the APDS-9930.

Q: What packaging considerations apply to substitution?

A: The APDS-9901 uses 8-SMD, No Lead packaging, while the APDS-9930 is specified as 8-SMD Module. Verify pinout compatibility and PCB footprint alignment with the module configuration before implementation.

Q: Are both components subject to the same moisture sensitivity requirements?

A: Yes. Both components carry MSL 3 (168 Hours) classification, requiring identical handling, storage, and reflow procedures during manufacturing.
