MPMA1002AT1 Equivalent & Substitute Parts

Part Overview

The MPMA1002AT1 is a 2-resistor network voltage divider manufactured by Vishay Dale Thin Film. This surface-mount component features dual 5kΩ resistors with ±0.1% tolerance and ±25ppm/°C temperature coefficient, designed for precision voltage divider applications requiring matched resistor pairs. The part is actively produced, AEC-Q200 qualified for automotive applications, and ROHS3 compliant. Substitute parts may be required due to inventory constraints, application-specific resistance values, or operational temperature range requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPMA1002AT1 is determined by the following critical parameters:

Mechanical Compatibility: Package type (TO-236-3/SOT-23-3), pin count (3), and physical dimensions (0.113" L × 0.051" W, 1.12mm max height) must remain identical to ensure PCB layout compatibility without redesign.

Electrical Performance: Tolerance (±0.1%), resistor matching ratio (±0.05%), and temperature coefficient (±25ppm/°C) define the precision class. Substitute parts must maintain these specifications for voltage divider accuracy.

Functional Parameters: Circuit type (voltage divider), number of resistors (2), and power rating per element (100mW) are fixed requirements.

Environmental Qualification: RoHS3 compliance and MSL rating (1 - Unlimited) are mandatory for the application context.

The MPMT2002AT1 qualifies as a substitute based on identical mechanical packaging, matching electrical tolerance and temperature coefficient specifications, and equivalent environmental compliance. The resistance value difference (10kΩ vs. 5kΩ) represents a functional variant suitable for applications requiring higher impedance voltage dividers with identical precision characteristics.

Engineering Selection Recommendations

MPMA1002AT1 (Primary): Select this part for applications requiring 5kΩ voltage divider networks with automotive-grade qualification (AEC-Q200). The extended operating temperature range (-55°C to 155°C) supports high-temperature automotive environments. Active product status ensures long-term availability and supply chain stability.

MPMT2002AT1 (Substitute): Select this part when 10kΩ resistance values are required for voltage divider applications. Electrical precision specifications (±0.1% tolerance, ±0.05% matching ratio, ±25ppm/°C temperature coefficient) are equivalent to the primary part. The operating temperature range (-55°C to 125°C) is suitable for standard industrial and consumer applications. ROHS3 compliance and unlimited MSL rating maintain environmental compatibility.

Both parts share identical mechanical packaging, pin configuration, and power ratings, enabling direct PCB footprint compatibility. Selection between them depends on the required resistance value and maximum operating temperature specification of the application circuit.

Frequently Asked Questions (FAQ)

Q: Can MPMT2002AT1 replace MPMA1002AT1 in any application?

A: Direct replacement is possible only if the application circuit design accommodates 10kΩ resistance values instead of 5kΩ. The mechanical package, pin count, and electrical precision are identical. If the circuit requires 5kΩ specifically, substitution requires circuit redesign.

Q: What is the impact of the operating temperature range difference?

A: MPMA1002AT1 operates to 155°C maximum, while MPMT2002AT1 operates to 125°C maximum. For applications requiring operation above 125°C, only MPMA1002AT1 is suitable. Both parts maintain ±25ppm/°C temperature coefficient within their respective ranges.

Q: Are both parts suitable for automotive applications?

A: MPMA1002AT1 carries AEC-Q200 automotive qualification. MPMT2002AT1 does not list automotive qualification. For automotive applications requiring AEC-Q200 compliance, MPMA1002AT1 is the specified choice.

Q: Do these parts require different PCB layouts?

A: No. Both parts use identical TO-236-3/SOT-23-3 packaging with 3 pins and matching physical dimensions (0.113" L × 0.051" W, 1.12mm max height). PCB footprints are interchangeable without layout modification.

Q: What determines the substitution eligibility between these parts?

A: Substitution is based on matching mechanical package specifications, identical electrical tolerance and temperature coefficient values, equivalent power ratings, and compatible environmental compliance ratings. Resistance value differences represent functional variants rather than direct equivalents.
