Substitute Part Grouping Explanation

Substitute parts for the UVZ2E220MHD1TO are classified based on the following substitution criteria:

Direct Substitutes maintain identical electrical specifications (22 µF, 250 V, ±20% tolerance) with matching mechanical dimensions and lead spacing (0.197" / 5.00 mm). These parts are pin-compatible and require no circuit modifications.

Upgrade Substitutes provide enhanced performance through higher voltage ratings (315 V, 350 V, 400 V) or extended lifetime ratings (10000 Hrs @ 105°C or 2000 Hrs @ 125°C) while maintaining the same 22 µF capacitance, ±20% tolerance, and mechanical compatibility. These parts are backward-compatible and offer improved reliability margins.

All substitute parts share the following mandatory parameters with the main part:

Capacitance: 22 µF
Tolerance: ±20%
Polarization: Polar
Mounting Type: Through Hole
Package Type: Radial, Can
Lead Spacing: 0.197" (5.00 mm)
Operating Temperature Range: -40°C to 105°C

Engineering Selection Recommendations

For Active Product Status Priority: Select from UCY2V220MHD3TO, UBT2E220MHD8TO, UCS2G220MHD1TO, UCS2V220MHD1TO, 350PX22MEFCG412.5X20, 400PX22MEFCG412.5X20, 860241178002, or EKXG401ETD220MK20S. All are classified as Active products and suitable for new designs.

For Nichicon Manufacturer Continuity: UCY2V220MHD3TO, UBT2E220MHD8TO, UCS2G220MHD1TO, and UCS2V220MHD1TO maintain Nichicon sourcing while providing active product status.

For Identical Voltage Rating (250 V): UBT2E220MHD8TO (Nichicon, Active) or 860241178002 (Würth Elektronik, Active) provide direct voltage compatibility. The Würth part offers extended 10000-hour lifetime but has a slightly larger diameter (0.512" vs. 0.492").

For Enhanced Reliability: UCS2G220MHD1TO, UCS2V220MHD1TO, 860241178002, and EKXG401ETD220MK20S provide 10000-hour lifetime ratings, doubling the operational life of the original part.

For Higher Voltage Margin: UCS2G220MHD1TO (400 V) and EKXG401ETD220MK20S (400 V) provide the highest voltage ratings with active product status and extended lifetime.

All recommended substitutes maintain ROHS3 compliance and are packaged in Cut Tape (CT) format matching the original part.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage-rated capacitor as a direct replacement? A: Yes. Higher voltage ratings (315 V, 350 V, 400 V) are backward-compatible with the 250 V application. The capacitor will operate safely at lower applied voltages. All substitute parts maintain the same 22 µF capacitance and ±20% tolerance, ensuring circuit functionality.

Q: What is the difference between Direct and Upgrade substitutes? A: Direct substitutes maintain identical electrical specifications. Upgrade substitutes provide enhanced performance through higher voltage ratings or extended lifetime ratings while maintaining electrical compatibility. Both categories are mechanically and electrically interchangeable.

Q: Does the Würth Elektronik part 860241178002 fit in the same PCB footprint? A: The Würth part has a slightly larger diameter (0.512" vs. 0.492") but maintains the same 0.197" (5.00 mm) lead spacing. Verify PCB hole diameter tolerance before substitution. Height and lead spacing are compatible.

Q: Why are some parts marked "Not For New Designs"? A: Parts with this status have been superseded by manufacturers but remain functionally equivalent. They are suitable for replacement or repair of existing assemblies but should not be selected for new product designs. Active alternatives are available.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant, matching the compliance status of the original UVZ2E220MHD1TO.

Q: What is the significance of lifetime ratings (2000 Hrs vs. 10000 Hrs)? A: Lifetime rating indicates operational hours at maximum rated temperature (105°C). Extended ratings (10000 Hrs) provide longer service life under thermal stress. For applications with continuous high-temperature operation, upgrade parts with extended ratings are recommended.

Q: Can I substitute a 250 V part with a 250 V part from a different manufacturer? A: Yes. UBT2E220MHD8TO (Nichicon) and 860241178002 (Würth Elektronik) both provide 250 V ratings with identical capacitance and tolerance. Both are Active products. The Würth part offers extended 10000-hour lifetime.
