Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPMT2001CT1 is determined by the following criteria:

• Identical resistance values (1kΩ, 1kΩ)
• Identical package and pinout (SOT-23-3)
• Identical power rating per element (100mW)
• Identical temperature coefficient (±25ppm/°C)
• Identical operating temperature range (-55°C ~ 125°C)
• Identical circuit type (Voltage Divider)
• Compliance with RoHS3 and REACH requirements

The MPMT2001AT1 meets all substitution criteria. It differs only in tolerance specification (±0.1% versus ±0.25%) and resistor matching ratio (±0.05% versus ±0.1%), both of which represent tighter specifications suitable for applications requiring higher precision.

Parameter Comparison

Engineering Selection Recommendations

Both MPMT2001CT1 and MPMT2001AT1 are active products with full compliance to ROHS3 and REACH requirements. The MPMT2001AT1 is suitable as a direct substitute where tighter tolerance and matching specifications are acceptable or required. Both parts maintain identical mechanical compatibility, thermal performance, and power handling characteristics. Selection between these parts depends on application tolerance requirements and availability.

Frequently Asked Questions (FAQ)

Q: Can MPMT2001AT1 replace MPMT2001CT1 in existing designs?

A: Yes. The MPMT2001AT1 is mechanically and electrically compatible. It features identical package dimensions, pinout, power rating, and temperature characteristics. The tighter tolerance (±0.1% versus ±0.25%) and improved matching ratio (±0.05% versus ±0.1%) make it suitable for applications requiring higher precision.

Q: What are the key differences between these parts?

A: The primary differences are tolerance specification and resistor matching ratio. MPMT2001AT1 provides ±0.1% tolerance and ±0.05% matching ratio, compared to ±0.25% tolerance and ±0.1% matching ratio for MPMT2001CT1. All other electrical and mechanical parameters are identical.

Q: Are both parts available in the same package?

A: Yes. Both parts use the SOT-23-3 package (TO-236-3, SC-59) with identical dimensions: 0.113" L x 0.051" W (2.86mm x 1.30mm) and maximum seated height of 0.044" (1.12mm).

Q: Do these parts have the same thermal performance?

A: Yes. Both parts have identical temperature coefficient (±25ppm/°C), operating temperature range (-55°C ~ 125°C), and resistor-ratio-drift (±2ppm/°C).

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both MPMT2001CT1 and MPMT2001AT1 are ROHS3 compliant and REACH unaffected. Both have MSL rating of 1 (unlimited moisture sensitivity).
