Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UCZ1E221MCS6GS is determined by the following critical parameters:

Electrical Parameters (Must Match):

• Capacitance: 220 µF
• Voltage Rating: 25 V
• Tolerance: ±20%
• ESR @ 100 kHz: 200 mOhm (primary electrical characteristic)
• Lifetime @ 125°C: 3000 Hrs

Mechanical Parameters (Must Match):

• Package Type: Radial, Can - SMD
• Case Diameter: 0.315" (8.00mm)
• Land Size: 0.327" L x 0.327" W (8.30mm x 8.30mm)
• Mounting Type: Surface Mount

Allowable Variations:

• Height: Parts with heights between 0.413" (10.50mm) and 0.425" (10.80mm) are mechanically compatible
• ESR tolerance: Minor variations acceptable if within circuit performance requirements
• Ripple current ratings: May vary based on series design

The substitute parts are grouped into two categories:

Direct Equivalents (Identical Electrical & Mechanical Specifications):

• UCZ1E221MCL6GS (Nichicon, same series, height 0.413")

Compatible Substitutes (Matching Core Parameters with Design Variations):

• 25TGV220M8X10.5 (Rubycon TGV series, lower ESR 150 mOhm, automotive rated)
• 25THV220M8X10.5 (Rubycon THV series, higher ESR 300 mOhm, automotive rated)
• EEE-TC1E221UV (Panasonic TCU series, anti-vibration, automotive rated, height 0.425")

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): UCZ1E221MCL6GS is the primary equivalent, offering identical electrical performance and the same 200 mOhm ESR characteristic. Both parts are from the Nichicon UCZ series and share the same general-purpose application profile. The 0.413" height is 0.012" shorter than the original, which is mechanically compatible with standard PCB land patterns.

For Active Product Status Requirement: If procurement of active, currently manufactured parts is required, select from the following:

• 25TGV220M8X10.5 (Rubycon TGV series) offers lower ESR at 150 mOhm, providing improved ripple current handling and thermal performance. AEC-Q200 automotive qualification is included.
• 25THV220M8X10.5 (Rubycon THV series) provides higher ESR at 300 mOhm with AEC-Q200 qualification, suitable for applications where lower ripple current is acceptable.
• EEE-TC1E221UV (Panasonic TCU series) matches the original 200 mOhm ESR specification exactly and includes anti-vibration design with AEC-Q200 automotive qualification. Height matches the original at 0.425".

For Automotive or High-Reliability Applications: All three active substitutes carry AEC-Q200 qualification. EEE-TC1E221UV is recommended for applications requiring anti-vibration performance and exact ESR matching. 25TGV220M8X10.5 is recommended where lower ESR and improved thermal characteristics are beneficial.

Compliance Considerations: All listed parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can UCZ1E221MCL6GS be used as a direct replacement for UCZ1E221MCS6GS? A: Yes. Both parts are from the Nichicon UCZ series with identical electrical specifications (220 µF, 25 V, ±20%, 200 mOhm ESR, 3000 Hrs @ 125°C). The only difference is height: 0.413" versus 0.425". This 0.012" difference is within standard PCB land pattern tolerances and does not affect electrical performance or mechanical fit.

Q: What is the difference between the Rubycon TGV and THV series substitutes? A: Both are Rubycon automotive-qualified parts with identical capacitance, voltage, and lifetime ratings. The primary difference is ESR: TGV series has 150 mOhm (lower), while THV series has 300 mOhm (higher). Lower ESR (TGV) provides better ripple current handling and lower heat generation. Higher ESR (THV) is suitable for applications with lower ripple current requirements. Select based on circuit ripple current specifications.

Q: Why does EEE-TC1E221UV have higher ripple current ratings than the original? A: The Panasonic TCU series is designed with enhanced thermal and electrical characteristics. The higher ripple current ratings (266.5 mA @ 120 Hz, 410 mA @ 100 kHz versus 135 mA and 270 mA) reflect improved performance capability. This part is a performance upgrade while maintaining the same 200 mOhm ESR and 3000 Hrs lifetime specification.

Q: Are all substitute parts compatible with the same PCB footprint? A: Yes. All parts share the same case diameter (0.315" / 8.00mm) and land size (0.327" L x 0.327" W / 8.30mm x 8.30mm). Height variations (0.413" to 0.425") are within standard SMD assembly tolerances and do not affect PCB layout compatibility.

Q: Which substitute should be selected for new designs? A: The original UCZ1E221MCS6GS is marked Not For New Designs. For new designs, select from active products: EEE-TC1E221UV (Panasonic) for exact ESR matching with anti-vibration features, or 25TGV220M8X10.5 (Rubycon) for lower ESR and improved thermal performance. Both carry AEC-Q200 qualification.

Q: What is the significance of AEC-Q200 qualification on the substitute parts? A: AEC-Q200 is the automotive electronics council qualification standard for passive components. Parts carrying this rating have undergone rigorous testing for reliability, temperature cycling, and performance stability. This qualification is relevant for automotive applications or systems requiring automotive-grade component reliability.

Q: Can these parts be used interchangeably in the same circuit? A: Electrical interchangeability is confirmed for all listed parts due to matching capacitance, voltage, tolerance, and lifetime specifications. However, circuit performance may vary slightly due to ESR differences. Applications sensitive to ESR (such as high-frequency switching circuits or low-noise power supplies) should evaluate the specific ESR value. General-purpose applications tolerate all ESR values listed without functional impact.
