Key Parameters

Substitute Part Grouping Explanation

Substitution of the UCZ1K220MCS6GS is determined by strict equivalence in the following parameters:

• Capacitance Value: Must remain 22 µF (no tolerance deviation acceptable for direct substitution)
• Tolerance: Must be ±20% or tighter
• Package Type: Must be Radial, Can - SMD with identical physical dimensions (8.00 mm diameter, 10.80 mm height)
• Land Size: Must match 8.30 mm × 8.30 mm for PCB compatibility
• Polarization: Must be polar (aluminum electrolytic)
• Series: Nichicon UCZ series maintains electrical and mechanical compatibility

The substitute part UCZ2A220MCS6GS qualifies as a direct upgrade substitute because it maintains all critical parameters while offering an increased voltage rating of 100 V (versus the original 80 V). This higher voltage rating provides additional design margin without compromising any other electrical or mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The UCZ2A220MCS6GS serves as a qualified substitute for the UCZ1K220MCS6GS in all applications where the original 80 V rating was specified. Both components maintain identical electrical performance characteristics (capacitance, ESR, ripple current, lifetime) and mechanical compatibility (package dimensions, land size, mounting type).

The substitute part's 100 V voltage rating represents an upgrade path suitable for designs operating at or below 80 V. Both components carry ROHS3 compliance and identical moisture sensitivity ratings, ensuring regulatory and environmental compatibility.

The "Not For New Designs" status of both parts indicates they are legacy components. For new product development, consultation with Nichicon's current product portfolio is recommended to identify actively supported alternatives within the UCZ series or successor product lines.

Frequently Asked Questions (FAQ)

Q: Can UCZ2A220MCS6GS replace UCZ1K220MCS6GS in existing designs?

A: Yes. The substitute maintains identical capacitance (22 µF), tolerance (±20%), ESR (750 mOhm @ 100 kHz), package dimensions (8.00 mm × 10.80 mm), and land size (8.30 mm × 8.30 mm). The increased voltage rating (100 V vs. 80 V) provides additional design margin without affecting circuit operation.

Q: Are there physical mounting differences between these parts?

A: No. Both components use identical surface mount radial can packaging with matching PCB land patterns (8.30 mm × 8.30 mm). No PCB redesign or rework is required for substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both UCZ1K220MCS6GS and UCZ2A220MCS6GS are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited).

Q: What is the significance of the "Not For New Designs" status?

A: This designation indicates both parts are legacy components no longer recommended for new product development. Existing designs using these parts may continue with the substitute, but new designs should evaluate current Nichicon product offerings.

Q: Are the electrical performance characteristics identical?

A: Yes. Both parts share identical ESR (750 mOhm @ 100 kHz), ripple current ratings (70 mA @ 100 kHz, 35 mA @ 120 Hz), operating temperature range (-40°C to 125°C), and lifetime specification (3000 Hrs @ 125°C).
