Key Parameters

Substitute Part Grouping Explanation

The MPMT4001AT1 qualifies as a direct substitute for the MPM4001AT1 based on identical electrical and mechanical specifications. Substitution is valid when the following parameters match:

• Resistance values: 2kΩ, 2kΩ
• Tolerance: ±0.1%
• Resistor matching ratio: ±0.05%
• Temperature coefficient: ±25ppm/°C
• Power per element: 100mW
• Number of resistors: 2
• Package type: SOT-23-3 (TO-236-3, SC-59)
• Number of pins: 3
• Operating temperature range: -55°C ~ 125°C

The primary difference between these parts is packaging format: MPM4001AT1 is supplied in Tape & Reel (TR) format, while MPMT4001AT1 is supplied in Cut Tape (CT) & Digi-Reel® format. Both parts are manufactured by Vishay Dale Thin Film and maintain identical electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both MPM4001AT1 and MPMT4001AT1 are active production parts from Vishay Dale Thin Film with identical electrical specifications and mechanical compatibility. Selection between these parts should be based on:

Packaging Format Requirements: Choose MPM4001AT1 for applications requiring standard Tape & Reel packaging. Select MPMT4001AT1 when Cut Tape or Digi-Reel® packaging is specified or preferred for assembly operations.

Compliance Requirements: MPMT4001AT1 carries ROHS3 compliance certification, while MPM4001AT1 is RoHS non-compliant. Applications subject to RoHS regulations must use MPMT4001AT1.

Inventory Availability: MPMT4001AT1 has higher current inventory (3005 pcs) compared to MPM4001AT1 (1133 pcs). Availability may influence selection for high-volume production schedules.

Frequently Asked Questions (FAQ)

Q: Can MPMT4001AT1 replace MPM4001AT1 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The only differences are packaging format and RoHS compliance status. PCB layout, schematic, and assembly processes require no modification.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, suitable for high-speed automated assembly. Cut Tape (CT) & Digi-Reel® packaging provides components on cut tape segments, typically used for lower-volume production or manual assembly operations.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical characteristics. Both parts deliver identical electrical performance across all specified parameters.

Q: Are these parts pin-compatible?

A: Yes. Both MPM4001AT1 and MPMT4001AT1 use identical SOT-23-3 packaging with 3 pins in the same configuration. No PCB redesign is required for substitution.

Q: What applications are these parts suitable for?

A: These voltage divider networks are designed for precision applications requiring matched resistor pairs with tight tolerance and low temperature coefficient drift, including analog signal conditioning, sensor interfaces, and precision measurement circuits.
