Substitute Part Grouping Explanation

Substitution of the MPMT5000CT1 is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Resistance values: 250, 250 Ohm
• Number of resistors: 2
• Circuit type: Voltage Divider
• Package type: SOT-23 (TO-236-3, SC-59)
• Number of pins: 3
• Power per element: 100mW
• Operating temperature range: -55°C to 125°C
• Temperature coefficient: ±25ppm/°C
• Resistor-ratio-drift: ±2ppm/°C
• Mounting type: Surface Mount
• RoHS compliance: ROHS3 Compliant
• MSL rating: 1 (Unlimited)

Allowable Parameter Variation:

• Tolerance: May be equal to or tighter than ±0.25%
• Resistor matching ratio: May be equal to or tighter than ±0.1%

The MPMT5000AT1 qualifies as a direct substitute because it maintains all mandatory equivalence criteria while offering improved tolerance (±0.1% versus ±0.25%) and tighter resistor matching ratio (±0.05% versus ±0.1%), making it functionally superior for precision applications.
