MPMT2003CT1 Equivalent & Substitute Parts

Part Overview

The MPMT2003CT1 is a 2-resistor network array manufactured by Vishay Dale Thin Film, configured as a voltage divider with dual 100kΩ resistors. This surface-mount component operates across -55°C to 125°C and is designed for precision applications requiring matched resistor pairs with controlled temperature coefficients. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and environmental specifications can be maintained within the allowed parameter tolerances for this resistor network category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPMT2003CT1 is determined by the following critical parameters:

• Resistance values must remain 100kΩ, 100kΩ
• Package and case designation must be TO-236-3, SC-59, SOT-23-3
• Operating temperature range must span -55°C to 125°C
• Temperature coefficient must be ±25ppm/°C
• Power per element must be 100mW
• Circuit type must be Voltage Divider
• Number of resistors must be 2
• Number of pins must be 3

The MPMT2003AT1 qualifies as a direct substitute because it maintains all critical electrical and mechanical parameters while offering improved tolerance specifications (±0.1% versus ±0.25%) and tighter resistor matching ratio (±0.05% versus ±0.1%). These enhancements represent superior performance characteristics within the same physical and functional envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the MPMT2003CT1 and MPMT2003AT1 are active production components with identical compliance certifications: ROHS3 compliance, REACH unaffected status, and EAR99 export classification. Both components carry MSL Level 1 (unlimited moisture sensitivity), indicating no moisture-related handling restrictions during storage or assembly.

The MPMT2003AT1 provides tighter tolerance specifications (±0.1% versus ±0.25%) and improved resistor matching ratio (±0.05% versus ±0.1%), making it suitable for applications requiring enhanced precision. The identical temperature coefficient (±25ppm/°C), power rating (100mW per element), and operating temperature range (-55°C to 125°C) ensure functional equivalence in voltage divider applications.

Selection between these parts depends on application-specific tolerance requirements. Both maintain identical physical dimensions, pinout configuration, and environmental performance characteristics.
