Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPMT2002FT1 is determined by the following critical parameters: package compatibility (SOT-23), circuit topology (voltage divider), number of resistors (2), pin count (3), power rating per element (100mW), temperature coefficient (±25ppm/°C), and operating temperature range (-55°C to 125°C). Resistance values and tolerance specifications define the precision class of the substitute.

Two substitute parts are identified:

MPMT2002AT1 qualifies as a direct substitute with identical resistance values (10kΩ, 10kΩ), improved tolerance (±0.1% vs. ±1%), and tighter resistor matching (±0.05% vs. ±0.5%). All other electrical and mechanical parameters remain equivalent.

MPMA1002AT1 qualifies as a functional substitute with different resistance values (5kΩ, 5kΩ) but maintains identical package, pin count, power rating, and temperature coefficient. This part includes automotive-grade qualification (AEC-Q200) and extended operating temperature range (-55°C to 155°C), with an expanded temperature range suitable for automotive applications.

Parameter Comparison

Engineering Selection Recommendations

MPMT2002AT1 is selected when the application requires identical 10kΩ resistance values with improved precision. The ±0.1% tolerance and ±0.05% resistor matching ratio provide tighter voltage divider accuracy compared to the MPMT2002FT1. Both parts maintain identical operating temperature ranges and package specifications, ensuring direct functional replacement in standard industrial applications.

MPMA1002AT1 is selected for automotive applications or environments requiring extended temperature operation to 155°C. The AEC-Q200 qualification certifies suitability for automotive-grade reliability. The 5kΩ resistance values require circuit redesign to maintain equivalent voltage divider ratios. This part is appropriate only when the application circuit can accommodate the different resistance values or when the voltage divider ratio adjustment is acceptable.

All three parts maintain ROHS3 compliance, unlimited moisture sensitivity rating, and active production status, ensuring long-term availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can MPMT2002AT1 replace MPMT2002FT1 without circuit modification?

A: Yes. MPMT2002AT1 maintains identical resistance values (10kΩ, 10kΩ), package (SOT-23), pin count (3), and operating temperature range (-55°C to 125°C). The improved tolerance (±0.1% vs. ±1%) and resistor matching (±0.05% vs. ±0.5%) enhance voltage divider accuracy without requiring circuit changes.

Q: Can MPMA1002AT1 replace MPMT2002FT1 without circuit modification?

A: No. MPMA1002AT1 features 5kΩ resistance values instead of 10kΩ. Direct substitution will alter the voltage divider ratio. Use MPMA1002AT1 only when the circuit design accommodates 5kΩ resistor values or when ratio adjustment is acceptable.

Q: What is the primary difference between MPMT2002FT1 and MPMT2002AT1?

A: Tolerance and resistor matching specifications differ. MPMT2002FT1 provides ±1% tolerance with ±0.5% matching, while MPMT2002AT1 provides ±0.1% tolerance with ±0.05% matching. All other electrical and mechanical parameters are identical.

Q: When should MPMA1002AT1 be selected over MPMT2002FT1?

A: Select MPMA1002AT1 for automotive applications requiring AEC-Q200 qualification or when operating temperatures exceed 125°C (up to 155°C maximum). The automotive-grade specification and extended temperature range are the primary selection criteria.

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

A: Yes. All three parts use the SOT-23 package with identical dimensions (0.113" L × 0.051" W, 2.86mm × 1.30mm) and 3-pin configuration, ensuring footprint compatibility across all substitutes.

Q: What compliance certifications apply to these parts?

A: All three parts are ROHS3 compliant and REACH unaffected. MPMA1002AT1 additionally carries AEC-Q200 automotive qualification. All parts maintain unlimited moisture sensitivity rating (MSL 1).
