ECA-2AM220 Equivalent & Substitute Parts

Part Overview

The ECA-2AM220 is a 22 µF, 100 V aluminum electrolytic capacitor in radial, can package manufactured by Panasonic Electronic Components. This component is rated for 2000 hours at 85°C and operates across -40°C to 85°C. The part maintains Active product status with full ROHS3 compliance and REACH unaffected certification.

Substitute parts become necessary when the ECA-2AM220 reaches end-of-life inventory depletion, when design revisions require alternative sourcing, or when supply chain constraints limit availability. The substitute parts listed maintain electrical equivalence across capacitance, voltage rating, tolerance, and thermal lifetime specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECA-2AM220 is determined by strict equivalence across the following parameters:

• Capacitance: 22 µF (exact match required)
• Voltage Rating: 100 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime @ Temperature: 2000 Hrs @ 85°C (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Polarization: Polar (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Type: Radial, Can (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

All three substitute parts meet these core electrical and mechanical criteria. Physical dimensions and lead spacing may vary within the radial can package envelope. ESR values, ripple current ratings, and MSL classifications are secondary parameters that do not restrict substitution eligibility but should be evaluated for specific circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

SK220M100ST (Cornell Dubilier Electronics) is the primary substitute for new designs and ongoing production. This part maintains Active product status, ensuring long-term availability and manufacturer support. It carries ROHS3 compliance and REACH unaffected certification identical to the ECA-2AM220.

UKL2A220MPD (Nichicon) is classified as Not For New Designs. This designation indicates the manufacturer has discontinued active development and support for this part number. Use of this substitute is restricted to legacy system maintenance or existing inventory depletion scenarios only.

UVR2A220MED (Nichicon) carries Obsolete product status. This part is no longer manufactured or supported by Nichicon. Selection of this substitute is not recommended for any application and should be avoided except in cases where existing circuit boards require direct replacement with identical part numbers.

All three substitutes maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements equivalent to the ECA-2AM220.

Frequently Asked Questions (FAQ)

Q: Can SK220M100ST replace ECA-2AM220 in existing designs?

A: Yes. SK220M100ST meets all core electrical parameters: 22 µF capacitance, 100 V voltage rating, ±20% tolerance, 2000 hour lifetime at 85°C, and -40°C to 85°C operating range. Both parts are through-hole radial can packages with ROHS3 compliance. Physical dimensions differ slightly (lead spacing 0.138" vs 0.098", can diameter 0.315" vs 0.248"), but both fit standard radial can footprints. Verify PCB layout clearances before implementation.

Q: Why is UKL2A220MPD marked "Not For New Designs"?

A: Nichicon has discontinued active development and support for the UKL series. This designation signals that the manufacturer will not guarantee long-term availability or provide technical updates. New designs should use SK220M100ST instead.

Q: Is UVR2A220MED still available for purchase?

A: UVR2A220MED is classified as Obsolete and is no longer manufactured by Nichicon. Current inventory of 947 pieces exists in stock, but no future production is planned. This part should not be selected for new applications.

Q: What are the physical dimension differences between substitutes?

A: ECA-2AM220 and UVR2A220MED share identical dimensions (0.248" diameter, 0.098" lead spacing, 0.480" height). SK220M100ST is larger (0.315" diameter, 0.138" lead spacing, 0.512" height). UKL2A220MPD is the largest (0.394" diameter, 0.197" lead spacing, 0.531" height). All fit through-hole radial can mounting, but verify PCB layout space availability.

Q: Do all substitutes have the same ESR specification?

A: ESR data is not provided for ECA-2AM220 and UKL2A220MPD. SK220M100ST specifies 4.83 Ohm ESR. If ESR is critical to circuit performance, obtain detailed specifications from the manufacturer before substitution.

Q: Are ripple current ratings equivalent across all parts?

A: Ripple current ratings vary. ECA-2AM220 specifies 115 mA @ 120 Hz and 195.5 mA @ 10 kHz. UKL2A220MPD specifies 136 mA @ 120 Hz and 272 mA @ 10 kHz. UVR2A220MED specifies 130 mA @ 120 Hz and 260 mA @ 10 kHz. SK220M100ST ripple current data is not provided. Evaluate ripple current requirements against each substitute's rating.

Q: What is the MSL classification difference?

A: ECA-2AM220 and UVR2A220MED are Not Applicable for MSL. SK220M100ST is MSL 1 (Unlimited). UKL2A220MPD is Not Applicable. MSL classification affects moisture sensitivity during storage and handling. Verify storage and handling procedures match the selected substitute's MSL level.
