Key Parameters

Substitute Part Grouping Explanation

Substitution for the UTT1C221MPD is determined by strict equivalence across the following parameters:

• Capacitance: 220 µF (exact match required)
• Voltage Rating: 16 V (exact match required)
• Tolerance: ±20% (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Type: Radial, Can (exact match required)
• Operating Temperature Range: -40°C ~ 105°C minimum (equal or wider range acceptable)
• Lifetime @ 105°C: 5000 Hrs minimum (equal or greater acceptable)

Substitute parts are grouped into two categories:

Direct Equivalents (Same Electrical & Mechanical Specifications): Parts meeting all core parameters with identical or superior performance ratings.

Compatible Alternatives (Different Mounting or Package Variants): Parts with matching electrical specifications but different physical form factors, suitable only when board layout permits.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation for Direct Replacement: EEU-FR1C221 (Panasonic Electronic Components)

The EEU-FR1C221 meets all electrical specifications of the UTT1C221MPD with identical capacitance, voltage rating, tolerance, and lifetime rating. This part carries Active product status with ROHS3 compliance, ensuring long-term availability and regulatory compliance. The lead spacing differs (0.098" vs. 0.138"), requiring PCB layout verification before implementation.

Alternative for Nichicon Continuity: UHV1C221MED (Nichicon)

The UHV1C221MED provides equivalent electrical performance with 5000-hour lifetime at 105°C and identical operating temperature range. This part is classified as Obsolete but maintains ROHS3 compliance. Physical dimensions differ significantly, particularly in lead spacing and height, necessitating board layout assessment.

Not Recommended for Direct Substitution:

• UPW1C221MPD: Lifetime rating of 3000 hours at 105°C falls below the 5000-hour requirement of the original part.
• UCW1C221MCL1GS: Surface mount package incompatible with through-hole PCB designs; suitable only for new designs with SMD-capable boards.
• UHV1E221MPD: Voltage rating of 25 V exceeds the 16 V specification; while electrically compatible in lower-voltage applications, this represents over-specification and cost inefficiency.

Frequently Asked Questions (FAQ)

Q: Can UPW1C221MPD replace UTT1C221MPD in existing designs?

A: UPW1C221MPD is not recommended. While it matches capacitance, voltage, and tolerance, its 3000-hour lifetime at 105°C is insufficient for applications requiring the 5000-hour rating of the original part. Use only if application lifetime requirements are lower.

Q: What is the primary difference between EEU-FR1C221 and EEU-FR1C221B?

A: Both parts are electrically identical. The difference is lead spacing: EEU-FR1C221 has 0.098" (2.50mm) spacing, while EEU-FR1C221B has 0.197" (5.00mm) spacing. Selection depends on PCB hole pattern design.

Q: Can UCW1C221MCL1GS be used as a substitute?

A: UCW1C221MCL1GS is a surface-mount variant with superior 7000-hour lifetime. It is electrically equivalent but requires SMD-capable PCB design and assembly equipment. It cannot be used as a direct replacement in through-hole applications.

Q: Why does UHV1E221MPD have a higher voltage rating?

A: UHV1E221MPD is rated for 25 V instead of 16 V. While it will function in 16 V circuits, it represents over-specification. Use only when higher voltage margin is required by design specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance, meeting regulatory requirements for restricted substances in electrical and electronic equipment.

Q: What should I verify before implementing a substitute part?

A: Verify PCB hole spacing and component height clearance against the substitute part's physical dimensions. Confirm that the application's lifetime requirement (5000 hours minimum at 105°C) is met by the substitute. Validate that operating temperature range (-40°C ~ 105°C minimum) is compatible with application requirements.
