Polarization: Polar (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required)
Package Type: Radial, Can (exact match required)
Mounting Type: Through Hole (exact match required)

Flexible Parameters (Substitution Allowed):

Voltage Rating: 160 V or higher (higher voltage ratings provide backward compatibility)
Lifetime @ Temperature: 5000 hours or longer at 105°C (longer lifetimes are acceptable)

Engineering Selection Recommendations

For Direct Replacement (Same Voltage, 160 V):

UPW2C220MPD (Nichicon) serves as a direct equivalent with identical electrical specifications and lifetime rating. However, physical dimensions differ slightly (smaller diameter and height), requiring PCB layout verification before substitution.

EKMG161ELL220MJ20S (Chemi-Con) and SEK220M160ST (Cornell Dubilier Electronics) are active alternatives at 160 V. EKMG161ELL220MJ20S has reduced lifetime (1000 hours versus 5000 hours), making it unsuitable for applications requiring the original 5000-hour specification. SEK220M160ST provides 2000-hour lifetime with different physical dimensions.

For Upgraded Performance (Higher Voltage Rating):

UCS2V220MHD (Nichicon, 350 V) and UCY2V220MHD3 (Nichicon, 350 V) provide higher voltage ratings with significantly extended lifetimes (10000 and 12000 hours respectively). These are direct physical and electrical upgrades with identical lead spacing and compatible mounting. UCY2V220MHD3 is REACH Affected; verify compliance requirements for your application.

UCS2G220MHD (Nichicon, 400 V) offers the highest voltage rating among Nichicon options with 10000-hour lifetime and active product status, making it the preferred long-term solution for new designs.

For Cross-Manufacturer Substitution:

450BXW22MEFR12.5X20 (Rubycon, 450 V) provides the highest voltage rating with 10000-hour lifetime and active status. Physical dimensions are compatible with the original part.

B43866C2226M (EPCOS - TDK Electronics, 250 V) and ESG226M250AL3AA (KEMET, 250 V) are active alternatives at 250 V. B43866C2226M operates at extended temperature range (-40°C to 125°C) with 5000-hour lifetime at 125°C. ESG226M250AL3AA has slightly larger diameter (0.512" versus 0.492") but maintains compatible lead spacing.

Product Status Considerations:

The original UPJ2C220MHD is obsolete. UVZ2E220MHD is marked "Not For New Designs." For new designs, select from active status parts: UCS2G220MHD, UCS2V220MHD, UCY2V220MHD3, 450BXW22MEFR12.5X20, B43866C2226M, or ESG226M250AL3AA.

All recommended substitutes are ROHS3 compliant and maintain the same capacitance, tolerance, polarization, and lead spacing as the original part.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage rated capacitor as a direct replacement?

A: Yes. A capacitor with higher voltage rating (250 V, 350 V, 400 V, or 450 V) is electrically compatible with a 160 V application. The circuit will operate normally, and the higher voltage rating provides additional safety margin. Verify that physical dimensions fit your PCB layout, as some substitutes have slightly different heights or diameters.

Q: What is the difference between UCS2V220MHD and UCY2V220MHD3?

A: Both are 22 µF, 350 V, ±20% tolerance capacitors with identical physical dimensions and lead spacing. UCY2V220MHD3 has extended lifetime (12000 hours versus 10000 hours) and is marked as REACH Affected, while UCS2V220MHD is REACH Unaffected. For applications requiring maximum lifetime, UCY2V220MHD3 is preferred; verify REACH compliance requirements for your region.

Q: Why does EKMG161ELL220MJ20S have lower lifetime than the original part?

A: EKMG161ELL220MJ20S is rated for 1000 hours at 105°C, compared to the original 5000 hours. This part is not suitable for applications requiring the original 5000-hour specification. It is listed as a similar alternative but does not meet the lifetime requirement.

Q: Are there physical dimension constraints I should consider?

A: Yes. Lead spacing (0.197" / 5.00 mm) is identical across all substitutes, ensuring PCB hole compatibility. However, diameter and height vary. UPW2C220MPD, EKMG161ELL220MJ20S, and SEK220M160ST have smaller diameters (0.394" versus 0.492"). ESG226M250AL3AA has slightly larger diameter (0.512"). Verify that your PCB layout accommodates these variations before substitution.

Q: Which substitute offers the best long-term availability?

A: UCS2G220MHD (Nichicon, 400 V, active status) is the recommended choice for new designs. It combines active product status, extended lifetime (10000 hours), high voltage rating (400 V), and full ROHS3 compliance. This ensures long-term availability and supply chain stability.

Q: Can I substitute across different manufacturers?

A: Yes. All listed substitutes maintain identical capacitance (22 µF), tolerance (±20%), polarization (polar), lead spacing (5.00 mm), and mounting type (through hole radial). Cross-manufacturer substitution is valid provided these parameters match. Verify compliance certifications (ROHS3, REACH) for your specific application requirements.

Q: What does "Not For New Designs" mean for UVZ2E220MHD?

A: This designation indicates the part is in mature or declining production phase. While electrically functional, it is not recommended for new product designs due to potential future discontinuation. For new designs, select from parts with "Active" status.
