Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EEU-ED2D221 is determined by the following critical parameters:

• Capacitance: Must be 220 µF (exact match required)
• Voltage Rating: Minimum 200 V (equal or higher acceptable)
• Tolerance: ±20% (standard tolerance match)
• Polarization: Polar (required for electrolytic type)
• Mounting Type: Through Hole (required for PCB compatibility)
• Package Type: Radial, Can (required for form factor compatibility)
• Lead Spacing: 0.295" (7.50mm) (required for footprint compatibility)
• Can Diameter: 0.709" (18.00mm) (required for mechanical fit)

Substitute parts are grouped into two categories:

Direct Equivalents: Parts matching all critical parameters including voltage rating (200 V), can diameter (18.00mm), and height specifications. These provide pin-for-pin compatibility with identical electrical performance.

Functional Equivalents: Parts matching capacitance, voltage, tolerance, and mounting specifications but with variations in lifetime rating, can diameter, or height. These require PCB layout verification before implementation.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: EEU-EE2D221 (Panasonic)

This part provides direct electrical and mechanical compatibility with the EEU-ED2D221. Both share identical capacitance (220 µF), voltage rating (200 V), tolerance (±20%), and lifetime rating (10000 Hrs @ 105°C). The can diameter matches at 0.709" (18.00mm), with a minimal height increase of 0.079" (2.00mm). ROHS3 compliance and identical lead spacing (0.295"/7.50mm) ensure PCB footprint compatibility without design modification.

Secondary Recommendation: UCY2E221MHD3 (Nichicon, Active Status)

This upgrade option offers superior performance characteristics: 250 V voltage rating (50 V margin above requirement), extended lifetime (12000 Hrs @ 105°C), and active product status ensuring long-term availability. The can diameter and lead spacing match the original part exactly. Height remains at 1.240" (31.50mm), identical to the EEU-ED2D221. ROHS3 compliance is confirmed. This part is suitable for applications requiring enhanced reliability margins.

Tertiary Recommendation: UPT2D221MHD6 (Nichicon, Active Status)

This part maintains 200 V voltage rating and 220 µF capacitance with active product status. The can diameter (0.709"/18.00mm) and lead spacing (0.295"/7.50mm) match the original specification. Height increases to 1.299" (33.00mm). Lifetime rating is 5000 Hrs @ 105°C, representing a 50% reduction from the original specification. This option is suitable for applications with relaxed lifetime requirements or where extended availability is prioritized.

Not Recommended: UPT2D221MHD (Nichicon)

While this part shares electrical specifications, the can diameter is 0.630" (16.00mm), deviating from the required 0.709" (18.00mm). This dimensional difference requires PCB layout verification and may necessitate design modification.

Frequently Asked Questions (FAQ)

Q: Can I use UCY2E221MHD3 as a direct replacement for EEU-ED2D221?

A: Yes. The UCY2E221MHD3 provides direct mechanical and electrical compatibility. The 250 V rating exceeds the 200 V requirement, and the 12000 Hrs lifetime exceeds the original 10000 Hrs specification. Lead spacing, can diameter, and height match the original part. Active product status ensures supply continuity.

Q: What is the difference between EEU-EE2D221 and EEU-ED2D221?

A: Both parts share identical electrical specifications (220 µF, 200 V, ±20%, 10000 Hrs @ 105°C). The primary difference is height: EEU-EE2D221 is 1.319" (34.60mm) versus EEU-ED2D221 at 1.240" (31.50mm). This 0.079" (2.00mm) increase requires verification of available PCB clearance before substitution.

Q: Why is UPT2D221MHD not recommended despite active status?

A: The can diameter is 0.630" (16.00mm), which deviates from the required 0.709" (18.00mm). This dimensional difference may cause mechanical interference or require PCB layout modification. UPT2D221MHD6 provides the correct can diameter with active status.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the original EEU-ED2D221 specification.

Q: What is the impact of reduced lifetime rating in UPT2D221MHD6?

A: The UPT2D221MHD6 provides 5000 Hrs @ 105°C versus the original 10000 Hrs. This represents a 50% reduction in rated lifetime. Selection depends on application duty cycle and required service life. For applications with continuous operation at elevated temperatures, higher lifetime ratings are preferred.

Q: Can I substitute parts with different can diameters?

A: No. Can diameter is a critical mechanical parameter. The original specification requires 0.709" (18.00mm). Parts with different diameters (such as UPT2D221MHD at 0.630"/16.00mm) may not fit existing PCB footprints and require design verification before implementation.

Q: What does "Active" product status mean?

A: Active status indicates the manufacturer currently produces and supports the part. Obsolete status indicates the part is no longer manufactured. For long-term supply security, active parts are preferred when electrical and mechanical specifications are equivalent.
