UPW2F220MHD Equivalent & Substitute Parts

Part Overview

The UPW2F220MHD is a 22 µF, 315 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The UPW series offers a 7000-hour lifetime rating at 105°C, suitable for general-purpose filtering and energy storage in power supply circuits.

Substitute Part Grouping Explanation

Substitution for the UPW2F220MHD is determined by the following critical parameters:

Capacitance Value: Must be 22 µF (±20% tolerance acceptable)
Voltage Rating: Minimum 315 V (higher ratings acceptable for backward compatibility)
Package Configuration: Radial, can format with 0.197" (5.00 mm) lead spacing and 0.492" (12.50 mm) case diameter
Mounting Type: Through-hole only
Polarization: Polar (aluminum electrolytic)
Operating Temperature: -40°C ~ 105°C minimum range
RoHS Compliance: ROHS3 Compliant required

Two substitute parts meet these criteria with varying performance characteristics and product status classifications.

Engineering Selection Recommendations

UCS2V220MHD (Recommended for New Designs)

The UCS2V220MHD is the preferred substitute for the obsolete UPW2F220MHD. This part carries Active product status and is suitable for new design implementations. The UCS series provides a 10000-hour lifetime at 105°C, exceeding the original UPW specification. The 350 V voltage rating provides additional margin above the 315 V requirement. Physical compatibility is maintained with identical lead spacing and case diameter, though the reduced height (21.50 mm vs. 25.00 mm) must be verified for PCB layout constraints. ROHS3 compliance and REACH unaffected status align with current regulatory requirements.

UVZ2F220MHD (Maintenance and Legacy Support)

The UVZ2F220MHD provides direct electrical compatibility with identical 315 V voltage rating and 22 µF capacitance. However, this part is classified as Not For New Designs and carries a reduced 2000-hour lifetime at 105°C compared to the original specification. The UVZ series is suitable only for replacement in existing equipment where design changes are not feasible. Physical dimensions are compatible with reduced height (22.00 mm), and full RoHS3 and REACH compliance is maintained.

Frequently Asked Questions (FAQ)

Q: Can UCS2V220MHD be used as a direct replacement for UPW2F220MHD?

A: Yes. Both parts share identical capacitance (22 µF), tolerance (±20%), lead spacing (5.00 mm), and case diameter (12.50 mm). The UCS2V220MHD operates at 350 V, which exceeds the 315 V requirement, providing additional voltage margin. Physical height differs (21.50 mm vs. 25.00 mm), requiring PCB layout verification.

Q: What is the difference between UVZ2F220MHD and UCS2V220MHD?

A: Both are Nichicon aluminum electrolytic capacitors with 22 µF capacitance and compatible physical dimensions. The UVZ2F220MHD maintains the original 315 V rating but offers only 2000 hours lifetime at 105°C. The UCS2V220MHD provides 350 V rating and 10000 hours lifetime at 105°C. The UCS series is Active status; the UVZ series is Not For New Designs.

Q: Are there height restrictions when substituting with UCS2V220MHD?

A: The UCS2V220MHD height is 21.50 mm compared to the original 25.00 mm. This reduction must be evaluated against PCB layout, clearance requirements, and mechanical constraints. Lead spacing and case diameter remain identical, ensuring footprint compatibility.

Q: Do substitute parts meet current compliance standards?

A: Both UVZ2F220MHD and UCS2V220MHD are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic components.

Q: Which substitute should be selected for new product designs?

A: UCS2V220MHD is the appropriate choice for new designs due to Active product status, extended 10000-hour lifetime rating, and higher 350 V voltage specification. UVZ2F220MHD is limited to maintenance and legacy support applications.
