Key Parameters

Substitute Part Grouping Explanation

Substitution of the RR111-1DC2-332 is governed by the following critical parameters:

Technology Compatibility: Both the main part and substitute must utilize magnetoresistive technology to ensure equivalent sensing principles and signal characteristics.

Output Type: The substitute must provide analog voltage output to maintain direct signal compatibility with existing interface circuitry.

Package Form Factor: Substitutes must use the 4-XFLGA package family with surface mount mounting type for PCB layout compatibility.

Voltage Supply Range: The substitute supply voltage range must encompass or overlap with the 2.7V ~ 3.6V requirement of the original design.

Operating Temperature Range: The substitute must support the -40°C ~ 85°C operating window to ensure reliable operation across the same environmental conditions.

Compliance Requirements: Both components must maintain ROHS3 compliance and equivalent moisture sensitivity ratings to ensure environmental and regulatory compatibility.

The substitute identified below satisfies these core substitution criteria while offering enhanced capabilities in sensing range and supply current efficiency.
