ECA-2EM220 Equivalent & Substitute Parts

Part Overview

The ECA-2EM220 is a 22 µF, 250 V aluminum electrolytic capacitor in radial, can package manufactured by Panasonic Electronic Components. This component is rated for 2000 hours at 85°C and is designed for general-purpose applications requiring through-hole mounting. The part is currently active in production.

Equivalent and substitute parts are necessary when the original component becomes unavailable, when design requirements demand extended operational lifetime, enhanced temperature performance, or when higher voltage ratings are required for circuit reliability.

Substitute Part Grouping Explanation

Substitution eligibility for the ECA-2EM220 is determined by the following criteria:

Primary Compatibility Requirements:

Capacitance: 22 µF (exact match required)
Tolerance: ±20% (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required)
Package Diameter: 0.394" (10.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Package / Case: Radial, Can (exact match required)

Secondary Compatibility Parameters (Allow Variation):

Voltage Rating: 250 V minimum (equal or higher voltage acceptable)
Operating Temperature Range: -25°C minimum lower bound (equal or lower acceptable)
Lifetime @ Temperature: 2000 Hrs @ 85°C minimum (equal or higher acceptable)
Package Height: 0.866" (22.00 mm) maximum (equal or lower acceptable)

Substitute parts are grouped into three categories:

Direct Equivalents (Same Voltage, Enhanced Performance): Parts maintaining 250 V rating with improved lifetime or temperature performance.

Upgrade Parts (Higher Voltage Rating): Parts rated at 350 V, providing overvoltage margin while maintaining all mechanical and electrical compatibility.

Legacy/Discontinued Parts: Parts no longer recommended for new designs but electrically compatible.

Engineering Selection Recommendations

For Active Production Designs:

Select from parts with Active product status. EEU-EE2E220 (Panasonic) and 250BXC22MEFC10X20 (Rubycon) provide the best balance of extended lifetime (8000 and 10000 hours respectively at 105°C) while maintaining the original 250 V rating and mechanical compatibility.

For Enhanced Reliability Requirements:

UCY2V220MPD9 (Nichicon) offers the highest operational lifetime at 12000 hours @ 105°C with 350 V rating, providing additional voltage margin. EKXJ351ELL220MJ20S (Chemi-Con) provides 10000 hours @ 105°C at 350 V with AEC-Q200 automotive qualification.

For Temperature-Extended Applications:

UCS2E220MPD (Nichicon) extends the lower operating temperature to -40°C while maintaining 8000 hours @ 105°C, suitable for applications requiring wider temperature performance.

For Legacy System Maintenance:

UVK2E220MPD (Nichicon) is electrically compatible but marked "Not For New Designs." Use only for replacement in existing systems where original specifications must be maintained.

Mechanical Fit Considerations:

Parts with 0.846" (21.50 mm) height (UCS2E220MPD, EKXJ351ELL220MJ20S, UCY2V220MPD9) are 0.020" shorter than the original. Verify PCB layout clearance before substitution. Parts with 0.866" (22.00 mm) height maintain exact mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can I substitute a 350 V rated capacitor for the 250 V original?

A: Yes. Higher voltage ratings are electrically compatible and provide overvoltage margin. Mechanical fit must be verified, as some 350 V parts have different package heights. Confirm PCB layout clearance.

Q: What is the difference between direct equivalents and upgrade parts?

A: Direct equivalents maintain the 250 V rating with improved lifetime or temperature performance. Upgrade parts are rated at 350 V, providing additional voltage safety margin while maintaining capacitance and tolerance specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the original ECA-2EM220.

Q: Can I use a part marked "Not For New Designs"?

A: UVK2E220MPD is electrically and mechanically compatible but is not recommended for new circuit designs. Use only for direct replacement in existing systems requiring exact specification matching.

Q: How do I determine if a substitute part fits my PCB?

A: Verify three parameters: lead spacing (0.197" / 5.00 mm), package diameter (0.394" / 10.00 mm), and package height. The original is 0.866" (22.00 mm) tall. Shorter alternatives at 0.846" (21.50 mm) require clearance verification.

Q: Which substitute offers the longest operational lifetime?

A: UCY2V220MPD9 (Nichicon) provides 12000 hours @ 105°C, the highest among all listed substitutes.

Q: What does "Lifetime @ Temperature" mean?

A: This specifies the expected operational duration before capacitance degradation reaches 80% of initial value at the stated temperature. Higher values indicate longer service life under thermal stress.
