Substitute Part Grouping Explanation

Substitution eligibility for the MPMT2003BT1 is determined by strict equivalence across the following critical parameters:

• Resistance values: Both elements must be 100kΩ
• Tolerance: ±0.1% maximum
• Circuit configuration: Voltage divider topology with 2 resistors
• Package: TO-236-3 / SOT-23-3 footprint
• Pin count: 3-pin configuration
• Power rating: 100mW per element minimum
• Temperature coefficient: ±25ppm/°C maximum
• Operating temperature range: -55°C to 125°C minimum
• Compliance: ROHS3 and REACH requirements

The MPMT2003AT1 meets all substitution criteria. Both parts share identical electrical specifications, mechanical dimensions, and environmental compliance certifications. The substitute part demonstrates superior resistor matching ratio (±0.05% versus ±0.1%), which represents an improvement over the original specification while maintaining full backward compatibility.
