MPMT2001FT1 Equivalent & Substitute Parts

Part Overview

The MPMT2001FT1 is a 2-resistor network voltage divider manufactured by Vishay Dale Thin Film in the MPM series. This surface-mount component features dual 1kΩ resistors with ±1% tolerance and ±25ppm/°C temperature coefficient in a compact SOT-23 package. The part is active and widely stocked, with 646 units currently available. Substitute parts may be required due to inventory constraints, design tolerance upgrades, or application-specific performance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPMT2001FT1 is determined by the following critical parameters:

• Identical resistance values (1kΩ, 1kΩ)
• Identical circuit topology (2-resistor voltage divider network)
• Identical package and pinout (SOT-23-3, 3-pin configuration)
• Identical power rating per element (100mW minimum)
• Identical operating temperature range (-55°C to 125°C)
• Identical temperature coefficient specification (±25ppm/°C)
• Same manufacturer series (MPM, Vishay Dale Thin Film)

The MPMT2001AT1 qualifies as a direct substitute based on these parameters. While the MPMT2001AT1 features improved tolerance (±0.1% versus ±1%) and tighter resistor matching (±0.05% versus ±0.5%), these represent performance enhancements rather than deviations from the core electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both MPMT2001FT1 and MPMT2001AT1 are active products from Vishay Dale Thin Film with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on application tolerance requirements and inventory availability.

The MPMT2001FT1 is suitable for general-purpose voltage divider applications where ±1% tolerance and ±0.5% resistor matching are acceptable. The MPMT2001AT1 provides superior tolerance performance (±0.1% and ±0.05% matching) for precision applications requiring tighter component specifications. Both parts maintain identical thermal performance, package dimensions, and operating characteristics across the full temperature range.

Frequently Asked Questions (FAQ)

Q: Can MPMT2001AT1 replace MPMT2001FT1 in existing designs?

A: Yes. The MPMT2001AT1 is electrically and mechanically compatible. It features identical resistance values, package configuration, power rating, and temperature coefficient. The tighter tolerance specifications of the substitute represent an enhancement rather than a limitation.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use the SOT-23-3 package with dimensions of 0.113" L × 0.051" W (2.86mm × 1.30mm) and maximum seated height of 0.044" (1.12mm). PCB footprints and assembly processes are interchangeable.

Q: What is the difference in tolerance between these parts?

A: MPMT2001FT1 specifies ±1% tolerance with ±0.5% resistor matching. MPMT2001AT1 specifies ±0.1% tolerance with ±0.05% resistor matching. The substitute provides tighter control of individual resistor values and their ratio to each other.

Q: Do both parts have identical temperature performance?

A: Yes. Both parts specify ±25ppm/°C temperature coefficient and operate across -55°C to 125°C. Thermal drift characteristics are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. Regulatory and environmental compliance is identical.
