Nichicon UTT1V220MDD Equivalent & Substitute Parts

Part Overview

The Nichicon UTT1V220MDD is a 22 µF, 35 V aluminum electrolytic capacitor in radial, can package configuration rated for 5000 hours at 105°C. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. The UTT series has been superseded by newer product lines with improved performance characteristics and extended availability.

Substitute Part Grouping Explanation

Substitution of the UTT1V220MDD is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Capacitance value must be 22 µF (±20% tolerance acceptable)
• Voltage rating must be equal to or greater than 35 V
• Operating temperature range must encompass -40°C to 105°C minimum

Mechanical Compatibility Requirements:

• Lead spacing must be 0.098" (2.50 mm)
• Case diameter must be 0.248" (6.30 mm)
• Mounting type must be Through Hole
• Package configuration must be Radial, Can

Compliance Requirements:

• RoHS3 compliance required
• REACH unaffected status required

The Nichicon UPW1J220MED meets all substitution criteria. It maintains identical capacitance, tolerance, lead spacing, case diameter, and mounting configuration while providing a higher voltage rating (63 V vs. 35 V) and improved electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The Nichicon UPW1J220MED is the direct substitute for the UTT1V220MDD. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The UPW1J220MED provides superior electrical performance with lower impedance (710 mOhms vs. 2.1 Ohms) and higher ripple current capacity (75 mA @ 120 Hz vs. 48 mA), while maintaining identical lead spacing and case diameter for direct PCB footprint compatibility.

The increased voltage rating (63 V vs. 35 V) and extended lower temperature operating range (-55°C vs. -40°C) provide additional design margin without circuit modification. The height difference (0.433" vs. 0.276") must be verified against available PCB clearance in the target application.

Frequently Asked Questions (FAQ)

Q: Can the UPW1J220MED be used as a direct replacement for the UTT1V220MDD?

A: Yes. The UPW1J220MED maintains identical capacitance (22 µF), tolerance (±20%), lead spacing (0.098"), and case diameter (0.248"). Both components use Through Hole mounting with Radial, Can package configuration. PCB footprint compatibility is confirmed.

Q: What is the height difference between these parts?

A: The UTT1V220MDD has a seated height of 0.276" (7.00 mm), while the UPW1J220MED has a seated height of 0.433" (11.00 mm). Verify available vertical clearance on the PCB before substitution.

Q: Does the higher voltage rating of the UPW1J220MED affect circuit operation?

A: No. A capacitor with a higher voltage rating operates normally in circuits designed for lower voltages. The 63 V rating of the UPW1J220MED provides additional design margin when used in 35 V applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the UTT1V220MDD and UPW1J220MED are ROHS3 compliant and REACH unaffected.

Q: What is the impedance difference between these parts?

A: The UTT1V220MDD has an impedance of 2.1 Ohms, while the UPW1J220MED has an impedance of 710 mOhms. The lower impedance of the substitute provides better high-frequency performance and reduced voltage ripple.
