Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OPT3002DNPT is determined by strict equivalence across the following critical parameters:

Sensor Type and Wavelength: The substitute must be an ambient light sensor with 505nm wavelength specification to maintain functional compatibility with existing optical measurement requirements.

Output Interface: I2C/SMBus protocol compatibility is mandatory for direct integration with host microcontroller interfaces without firmware modification.

Electrical Specifications: Supply voltage range (1.6V – 3.6V) and operating temperature range (-40°C to 85°C) must be identical or encompassing to ensure operation within the same system power and thermal constraints.

Package and Mounting: The 6-UDFN Exposed Pad package with surface mount configuration must be preserved for PCB layout compatibility.

Compliance Standards: RoHS3 compliance and REACH unaffected status must be maintained for regulatory and supply chain continuity.

The OPT3002DNPR qualifies as a direct substitute based on complete parameter alignment across all critical categories.

Parameter Comparison

Engineering Selection Recommendations

The OPT3002DNPR is the designated substitute for the obsolete OPT3002DNPT. Both components share identical electrical, optical, and mechanical specifications, ensuring direct functional equivalence. The primary distinction is product status: OPT3002DNPT is obsolete while OPT3002DNPR maintains active production status, providing supply chain continuity and long-term availability.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and legacy system support. The transition from OPT3002DNPT to OPT3002DNPR requires no circuit modifications, firmware changes, or PCB layout alterations.
