Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the UAS2G220MHD are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Capacitance: 22 µF
• Voltage Rating: 400 V
• Tolerance: ±20%
• Polarization: Polar

Mechanical Parameters (Must Match):

• Package Type: Radial, Can
• Mounting Type: Through Hole
• Lead Spacing: 0.197" (5.00mm)
• Diameter: 0.492" (12.50mm)

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Operating Temperature Range: -40°C ~ 105°C

All identified substitute parts meet these core requirements. Variations in lifetime rating, ripple current capacity, and physical height do not preclude substitution when the above parameters align.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory conformance. Selection between the UAS2G220MHD and its substitutes depends on application-specific requirements:

UCS2G220MHD (Nichicon): Extended lifetime rating of 10000 hours at 105°C and elevated ripple current capacity (760 mA @ 100 kHz) provide enhanced performance margin for demanding applications. Marginal height reduction (21.50mm vs. 22.00mm) maintains PCB layout compatibility.

400AX22MEFC12.5X16 (Rubycon): Equivalent 2000-hour lifetime rating matches the original UAS2G220MHD specification. Reduced physical height (18.00mm) offers space optimization benefit for compact designs while maintaining electrical equivalence.

EKXG401ELL220MK20S (Chemi-Con): Extended lifetime rating of 10000 hours at 105°C with high ripple current capacity (650 mA @ 100 kHz) supports long-term reliability requirements. Physical height of 20.00mm provides intermediate dimensional profile.

Frequently Asked Questions (FAQ)

Q: Can UCS2G220MHD replace UAS2G220MHD directly?

A: Yes. Both parts share identical electrical specifications (22 µF, 400 V, ±20% tolerance) and mechanical configuration (radial, through-hole, 5.00mm lead spacing, 12.50mm diameter). The UCS series offers extended lifetime (10000 hours vs. 2000 hours) and higher ripple current capacity, making it a direct functional replacement with performance enhancement.

Q: What is the impact of different physical heights on PCB design?

A: The substitute parts exhibit height variations ranging from 18.00mm to 22.00mm. The 400AX22MEFC12.5X16 (18.00mm) provides maximum clearance benefit, while UCS2G220MHD (21.50mm) and EKXG401ELL220MK20S (20.00mm) remain within acceptable tolerance for standard through-hole PCB layouts. Verify clearance against component placement constraints in your specific design.

Q: Are ripple current differences significant for substitution?

A: Ripple current ratings indicate thermal stress handling capacity. Higher ripple current ratings (UCS2G220MHD at 760 mA @ 100 kHz, EKXG401ELL220MK20S at 650 mA @ 100 kHz) provide additional thermal margin compared to the original UAS2G220MHD (264 mA @ 10 kHz). Substitution is valid when circuit ripple current does not exceed the substitute part's rating.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All listed substitutes are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS code 8532.22.0020, ensuring regulatory equivalence for procurement and deployment.

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

A: UCS2G220MHD and EKXG401ELL220MK20S both provide 10000-hour lifetime ratings at 105°C, compared to 2000 hours for the original UAS2G220MHD and 400AX22MEFC12.5X16. Extended lifetime rating supports applications requiring extended service intervals or elevated ambient temperature exposure.
