Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPMT2001DT1 is determined by the following criteria:

• Identical resistance values (1kΩ, 1kΩ)
• Identical number of resistors (2)
• Identical package and pinout (TO-236-3, SC-59, SOT-23-3)
• Identical power rating per element (100mW)
• Identical temperature coefficient (±25ppm/°C)
• Identical operating temperature range (-55°C ~ 125°C)
• Identical mounting type (Surface Mount)
• Tolerance equal to or tighter than ±0.5%
• Identical circuit type (Voltage Divider)

The MPMT2001AT1 meets all substitution criteria with an improved tolerance specification of ±0.1%, making it a direct substitute for the MPMT2001DT1.

Parameter Comparison

Engineering Selection Recommendations

Both MPMT2001DT1 and MPMT2001AT1 are active products with full ROHS3 compliance and REACH unaffected status. The MPMT2001AT1 provides tighter tolerance (±0.1% versus ±0.5%) and improved resistor matching ratio (±0.05% versus ±0.1%), while maintaining identical electrical performance in all other parameters. Selection between these parts depends on application tolerance requirements. The MPMT2001AT1 is suitable for applications requiring higher precision voltage divider performance.

Frequently Asked Questions (FAQ)

Q: Can MPMT2001AT1 replace MPMT2001DT1 in existing designs?

A: Yes. The MPMT2001AT1 is a direct substitute with identical package, pinout, resistance values, power rating, and temperature characteristics. The improved tolerance specification of the MPMT2001AT1 makes it compatible with all applications designed for the MPMT2001DT1.

Q: What is the difference in tolerance between these parts?

A: The MPMT2001DT1 has ±0.5% tolerance, while the MPMT2001AT1 has ±0.1% tolerance. The MPMT2001AT1 also provides superior resistor matching ratio (±0.05% versus ±0.1%), beneficial for precision voltage divider circuits.

Q: Are the packages identical?

A: Yes. Both parts use the TO-236-3, SC-59, SOT-23-3 package with identical dimensions (0.113" L x 0.051" W, 2.86mm x 1.30mm) and maximum seated height (0.044", 1.12mm).

Q: Do both parts meet the same compliance standards?

A: Yes. Both MPMT2001DT1 and MPMT2001AT1 are ROHS3 compliant, REACH unaffected, and classified as EAR99 with identical HTSUS codes.

Q: Which part should be selected for new designs?

A: Selection depends on tolerance requirements. For applications requiring ±0.5% tolerance, either part is suitable. For applications requiring tighter tolerance and improved matching characteristics, the MPMT2001AT1 is the appropriate choice.
