Key Parameters

Substitute Part Grouping Explanation

Substitution of the BLE112-N-V1 is determined by the following critical parameters:

RF Communication Standard: Both the main part and substitute must operate within the Bluetooth protocol family to maintain system-level compatibility.

Data Rate Compatibility: The substitute must support a minimum data rate of 2Mbps to ensure functional equivalence in serial communication throughput.

Serial Interface Support: The substitute must provide at least SPI and UART interfaces to maintain compatibility with existing host controller designs.

Voltage Supply Range: The substitute supply voltage range must encompass or overlap with the original 2V to 3.6V specification to ensure operation within the same power delivery architecture.

Mounting Type: Surface mount packaging is required to maintain PCB assembly compatibility.

Operating Temperature Range: The substitute must support the full -40°C to 85°C operating temperature range.

Regulatory Compliance: RoHS3 compliance and equivalent ECCN/HTSUS classifications ensure regulatory and export control alignment.

The BGM220PC22WGA2R meets these substitution criteria through its Bluetooth v5.2 protocol support, enhanced data rate capability, expanded serial interface set, compatible voltage supply range, surface mount packaging, and maintained operating temperature specification.
