Substitute Part Grouping Explanation

Substitution eligibility for the MPMT2002BT1 is determined by the following criteria:

Direct Substitutes maintain identical electrical specifications: 10kΩ dual-resistor configuration, ±0.1% tolerance, 100mW power per element, ±25ppm/°C temperature coefficient, and SOT-23 package compatibility. The MPMT2002AT1 qualifies as a direct substitute with these matching parameters.

Application-Specific Alternatives may differ in resistance value or operating temperature range while maintaining the same package, pin count, circuit topology, and core electrical characteristics (tolerance, power rating, temperature coefficient). The MPMA1002AT1 represents this category with 5kΩ resistors and extended operating temperature to 155°C, suitable for automotive applications requiring AEC-Q200 qualification.

Parameter Comparison

Engineering Selection Recommendations

MPMT2002AT1 is the primary direct substitute for MPMT2002BT1. Both parts are active products with identical resistance values, tolerance, power rating, and temperature coefficient. The MPMT2002AT1 offers improved resistor matching ratio (±0.05% versus ±0.1%), providing enhanced precision for voltage divider applications. Both parts comply with ROHS3 and operate within the same temperature range (-55°C to 125°C). Selection between these two depends on inventory availability and matching precision requirements.

MPMA1002AT1 is an application-specific alternative suitable only when circuit design permits 5kΩ resistor values instead of 10kΩ. This part extends the operating temperature range to 155°C and includes AEC-Q200 automotive qualification, making it appropriate for automotive-grade applications. The identical package, pin count, and core electrical characteristics (tolerance, power rating, temperature coefficient) ensure mechanical and thermal compatibility. However, the different resistance value requires circuit-level verification before implementation.

Frequently Asked Questions (FAQ)

Q: Can MPMT2002AT1 replace MPMT2002BT1 without circuit modification?

A: Yes. Both parts feature identical 10kΩ dual-resistor configuration, ±0.1% tolerance, 100mW power per element, ±25ppm/°C temperature coefficient, and SOT-23-3 package. The MPMT2002AT1 provides superior resistor matching (±0.05%), making it a direct electrical and mechanical substitute.

Q: Is MPMA1002AT1 compatible with designs specified for MPMT2002BT1?

A: MPMA1002AT1 is mechanically compatible (identical SOT-23 package and pin count) but electrically different due to 5kΩ resistor values versus 10kΩ. Circuit-level analysis is required to determine if the lower resistance values are acceptable for the application. This part is intended for automotive applications requiring AEC-Q200 qualification and extended temperature operation to 155°C.

Q: What are the key differences between MPMT2002BT1 and MPMT2002AT1?

A: The primary difference is resistor matching ratio: MPMT2002BT1 specifies ±0.1% while MPMT2002AT1 specifies ±0.05%. All other electrical parameters (resistance, tolerance, power rating, temperature coefficient) and mechanical specifications (package, pin count, dimensions) are identical. Both are active products with ROHS3 compliance.

Q: When should MPMA1002AT1 be selected over MPMT2002AT1?

A: MPMA1002AT1 should be selected when the application requires automotive-grade components with AEC-Q200 qualification and extended operating temperature to 155°C. The 5kΩ resistor values must be compatible with circuit design. For standard industrial applications within -55°C to 125°C, MPMT2002AT1 is the appropriate choice.

Q: Are all three parts available in the same package?

A: Yes. MPMT2002BT1, MPMT2002AT1, and MPMA1002AT1 all use the TO-236-3 / SC-59 / SOT-23-3 package with identical dimensions (0.113" L × 0.051" W, 2.86mm × 1.30mm) and maximum seated height (0.044" / 1.12mm). All are surface-mount components with 3 pins.
