Substitute Part Grouping Explanation

Substitution eligibility for the MPMT2002DT1 is determined by the following critical parameters:

Primary Substitution Criteria (Must Match):

• Circuit type: Voltage Divider
• Number of resistors: 2
• Package / Case: TO-236-3, SC-59, SOT-23-3
• Mounting type: Surface Mount
• Power per element: 100mW
• Temperature coefficient: ±25ppm/°C
• Number of pins: 3

Secondary Substitution Criteria (Allowable Variation):

• Resistance values: Must be functionally equivalent for the application
• Tolerance: May be equal or tighter (lower tolerance values are acceptable)
• Resistor matching ratio: May be equal or tighter
• Operating temperature range: May be equal or extended
• Product status: Must be Active

Substitute parts are grouped into two categories:

Direct Substitutes (Identical Specifications): Parts that match all primary and secondary criteria with identical or superior electrical performance.

Functional Equivalents (Application-Dependent): Parts that maintain package and circuit compatibility but with different resistance values, requiring circuit-level verification for specific applications.

Frequently Asked Questions (FAQ)

Q: Can MPMT2002AT1 be used as a direct replacement for MPMT2002DT1?

A: Yes. Both parts feature identical 10kΩ, 10kΩ resistance values, SOT-23 package configuration, and operating temperature range (-55°C to 125°C). The MPMT2002AT1 provides superior tolerance and matching specifications, making it a direct substitute with improved performance characteristics.

Q: What is the key difference between MPMT2002DT1 and MPMA1002AT1?

A: The primary difference is resistance value. MPMT2002DT1 contains 10kΩ resistors, while MPMA1002AT1 contains 5kΩ resistors. Both share identical package, power rating, and temperature coefficient. MPMA1002AT1 is qualified for automotive applications (AEC-Q200) and supports an extended temperature range to 155°C. Substitution requires verification that 5kΩ values are appropriate for the circuit design.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the TO-236-3, SC-59, SOT-23-3 package with identical physical dimensions (0.113" L × 0.051" W, height 0.044" max). They are mechanically and electrically compatible with the same surface-mount footprint.

Q: Which substitute part should be selected for automotive applications?

A: MPMA1002AT1 is qualified for automotive use with AEC-Q200 certification and Automotive grade designation. If 5kΩ resistance values are functionally appropriate for the application, MPMA1002AT1 is the recommended selection. Otherwise, MPMT2002AT1 is suitable for non-automotive applications requiring 10kΩ values.

Q: What is the significance of the resistor matching ratio specification?

A: The resistor matching ratio defines the maximum tolerance between the two resistors within the network. MPMT2002DT1 specifies ±0.1% matching, while both substitute parts offer tighter ±0.05% matching. Tighter matching improves voltage divider accuracy and reduces output impedance variation across temperature and time.

Q: Are moisture sensitivity considerations different between these parts?

A: No. All three parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity precautions are required during storage, handling, or assembly.
