Substitute Part Grouping Explanation

Substitution eligibility is determined by the following mandatory parameters:

Capacitance: Must equal 22 µF
Voltage - Rated: Must be ≥ 250 V
Tolerance: Must be ±20%
Polarization: Must be Polar
Mounting Type: Must be Through Hole
Package / Case: Must be Radial, Can
Lead Spacing: Must be 0.197" (5.00 mm)

Engineering Selection Recommendations

EEU-ED2E220B (Panasonic): Direct substitute with extended operational life. Rated for 8000 hours at 105°C versus 2000 hours at 85°C for the original part. Active product status supports long-term availability. ROHS3 compliant. Suitable for applications requiring enhanced reliability without voltage rating changes.

UCS2E220MPD1TD (Nichicon): Direct substitute with equivalent electrical specifications and extended lifetime. Rated for 8000 hours at 105°C. Operating temperature range extends to -40°C. Active product status. ROHS3 compliant. Slightly reduced height (21.50 mm) provides additional PCB clearance. Suitable for general-purpose replacement.

UCY2V220MPD9TD (Nichicon): Upgrade substitute with increased voltage rating of 350 V and extended lifetime of 12000 hours at 105°C. Operating temperature range extends to -40°C. Active product status. REACH Affected status requires compliance verification for specific applications. Suitable for applications requiring enhanced voltage margin and extended operational life.

UVK2E220MPD1TD (Nichicon): Not recommended for new designs. Product status is "Not For New Designs." Equivalent electrical specifications to the original part but lower ripple current ratings. ROHS3 compliant. Use only for legacy system maintenance or replacement in existing designs.

Frequently Asked Questions (FAQ)

Q: Can EEU-ED2E220B replace ECA-2EM220B directly on the PCB?

A: Yes. Both parts share identical lead spacing (5.00 mm), diameter (10.00 mm), and maximum height (22.00 mm). Electrical specifications are compatible: 22 µF capacitance, ±20% tolerance, 250 V rating, and polar radial can package. The EEU-ED2E220B offers extended lifetime (8000 hours at 105°C) as an added benefit.

Q: What is the difference between the Panasonic and Nichicon substitutes?

A: All substitutes meet the core electrical and mechanical requirements. Panasonic EEU-ED2E220B maintains the same manufacturer as the original. Nichicon UCS2E220MPD1TD and UCY2V220MPD9TD offer extended operating temperature ranges (-40°C minimum) and higher ripple current ratings. UCY2V220MPD9TD provides a 350 V voltage rating upgrade.

Q: Can UCY2V220MPD9TD be used as a drop-in replacement?

A: Yes, mechanically and electrically. The 350 V rating is compatible with 250 V applications and provides additional voltage margin. Height is 21.50 mm, which is 0.50 mm shorter than the original, allowing improved PCB clearance. REACH Affected status must be verified for compliance with specific application requirements.

Q: Why is UVK2E220MPD1TD marked "Not For New Designs"?

A: This designation indicates the product is in end-of-life status. While electrically compatible, it should not be selected for new circuit designs. Use only for maintenance or replacement in existing systems where the part is already deployed.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitutes, including the original ECA-2EM220B, are ROHS3 compliant. This ensures compatibility with environmental and regulatory requirements across standard applications.

Q: What is the impact of different ripple current ratings?

A: Ripple current capacity indicates the maximum AC current the capacitor can handle without exceeding temperature limits. Higher ripple current ratings (EEU-ED2E220B, UCS2E220MPD1TD, UCY2V220MPD9TD) provide greater margin in high-frequency switching applications. Selection depends on actual circuit ripple current requirements.
