ECA-2DM220 Equivalent & Substitute Parts

Part Overview

The ECA-2DM220 is a 22 µF, 200 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 classified as Active product status. Substitute parts are necessary when the original component becomes unavailable, when design requirements demand extended operational lifetime, higher voltage ratings, or improved temperature performance characteristics.

Substitute Part Grouping Explanation

Substitution eligibility for the ECA-2DM220 is determined by the following criteria:

Direct Substitutes maintain identical electrical specifications: 22 µF capacitance, 200 V voltage rating, ±20% tolerance, and identical physical dimensions (0.394" diameter, 0.866" height, 5.00mm lead spacing). These parts are mechanically and electrically interchangeable without circuit modification.

Upgrade Substitutes increase one or more of the following parameters while maintaining mechanical compatibility:

Voltage rating (250 V or 350 V rated parts can replace 200 V applications)
Lifetime at temperature (8000 Hrs, 10000 Hrs, or 12000 Hrs rated parts exceed 2000 Hrs requirement)
Operating temperature range (extended to 105°C or -40°C minimum)

All substitute candidates must maintain the same package type (Radial, Can), lead spacing (5.00mm), and mounting method (Through Hole) to ensure PCB compatibility.

Engineering Selection Recommendations

Direct Substitution (Same Electrical & Mechanical Specifications):

ECA-2DHG220 is the primary direct substitute. It maintains 22 µF capacitance and 200 V voltage rating with identical physical dimensions. The upgrade to 105°C operating temperature and AEC-Q200 automotive qualification provides enhanced reliability without circuit modification. Product status is Active.

Recommended Upgrade Substitutes (Enhanced Performance):

EEU-EE2D220 (Panasonic) provides 4× lifetime extension (8000 Hrs @ 105°C) while maintaining 200 V rating and identical package dimensions. Active product status ensures long-term availability.

250BXC22MEFC10X20 (Rubycon) offers voltage upgrade to 250 V with 10000 Hrs @ 105°C lifetime. Maintains 0.866" height for direct PCB fit. Active product status.

EKXJ351ELL220MJ20S (Chemi-Con) provides maximum voltage upgrade to 350 V with 10000 Hrs @ 105°C lifetime and extended temperature range (-40°C to 105°C). AEC-Q200 automotive qualification included. Active product status.

Avoid:

UCA2D220MPD (Nichicon) is classified as Obsolete and should not be selected for new designs despite superior 10000 Hrs @ 105°C rating.

UCY2V220MPD9 (Nichicon) carries REACH Affected status, requiring compliance verification for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can I use a 250 V rated capacitor in place of the 200 V ECA-2DM220?

A: Yes. Higher voltage-rated capacitors are electrically compatible in lower voltage applications. A 250 V or 350 V rated part will function correctly in a 200 V circuit. Physical dimensions must remain compatible with PCB layout.

Q: What is the significance of lifetime ratings (2000 Hrs vs. 8000 Hrs vs. 10000 Hrs)?

A: Lifetime rating indicates the expected operational duration at the specified temperature before capacitance degradation reaches ±20% tolerance limits. Extended lifetime ratings provide longer service intervals and reduced field failure risk in continuous-duty applications.

Q: Are all substitute parts mechanically compatible with the original PCB?

A: Most substitutes maintain the 5.00mm lead spacing and 0.394" diameter. However, height varies: ECA-2DM220, EEU-EE2D220, 250BXC22MEFC10X20, and 250CFX22MEFC10X20 are 0.866" tall, while UCA2D220MPD, 226CKE250MLU, EKXJ351ELL220MJ20S, UCS2E220MPD, and UCY2V220MPD9 are 0.846" tall. Verify clearance in confined spaces.

Q: What does AEC-Q200 qualification mean?

A: AEC-Q200 is an automotive electronics qualification standard. Parts bearing this rating (ECA-2DHG220, EKXJ351ELL220MJ20S) meet automotive reliability and temperature cycling requirements. This certification is optional for general-purpose applications.

Q: Why is UCA2D220MPD listed as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. While inventory may remain available, long-term sourcing is not guaranteed. Active product alternatives should be prioritized for new designs.

Q: Can I substitute a part with a lower voltage rating?

A: No. A 200 V capacitor cannot replace a higher voltage requirement. Voltage rating must equal or exceed circuit requirements to prevent dielectric breakdown and component failure.
