ECO-S2AP222BA Equivalent & Substitute Parts

Part Overview

The ECO-S2AP222BA is a 2200 µF, 100 V aluminum electrolytic capacitor manufactured by Panasonic Electronic Components in the TS-UP series. This radial, can-style snap-in capacitor is designed for general-purpose applications requiring high capacitance and voltage ratings. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain electrical performance characteristics including capacitance, voltage rating, ESR, and thermal lifetime specifications while accommodating mechanical form factor variations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECO-S2AP222BA is determined by strict adherence to the following electrical and mechanical parameters:

Mandatory Matching Parameters:

• Capacitance: 2200 µF (exact)
• Tolerance: ±20% (exact)
• Voltage - Rated: 100 V (exact)
• Polarization: Polar (exact)
• Lead Spacing: 0.394" (10.00 mm) (exact)
• Mounting Type: Through Hole (exact)
• Package / Case: Radial, Can - Snap-In (exact)

Acceptable Variation Parameters:

• ESR: 121 mOhm @ 120 Hz (equivalent or lower)
• Lifetime @ Temperature: 3000 Hrs @ 85°C (equivalent or greater)
• Operating Temperature Range: -40°C ~ 85°C (equivalent or wider)
• Physical Dimensions (Diameter and Height): Minor variations acceptable within mechanical constraints

All substitute parts listed maintain the mandatory electrical specifications. Variations in physical dimensions reflect different manufacturer design approaches while preserving functional compatibility in snap-in mounting applications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are active products with ROHS3 compliance, providing regulatory advantage over the obsolete ECO-S2AP222BA. Selection among substitutes depends on mechanical space constraints within the application:

Compact Form Factor (Smallest Footprint): SLPX222M100E3P3 offers the most compact dimensions at 1.181" diameter and 1.181" height, suitable for space-constrained applications.

Standard Compact Form Factor: SLPX222M100A4P3 provides reduced height (1.772") while maintaining 0.866" diameter, appropriate for applications with vertical space limitations.

Mid-Range Dimensions: SLPX222M100C7P3 and 380LX222M100J042 offer balanced form factors with 0.984" to 1.181" diameters and heights between 1.575" and 1.654".

Larger Diameter Options: 380LX222M100K022 features the largest diameter (1.181") with minimal height (1.260"), suitable for applications prioritizing low profile.

Direct Size Match: 380LX222M100H052 maintains the original 0.866" diameter with minimal height increase (2.047"), providing closest dimensional compatibility.

Alternative Manufacturer: B41231A9228M000 from EPCOS - TDK Electronics matches the original 0.866" diameter and 1.850" height. Note that ESR specification is not provided for this part; thermal lifetime is 2000 Hrs @ 85°C, which is lower than the 3000 Hrs specification of other substitutes.

All substitute parts maintain the required 2200 µF capacitance, ±20% tolerance, 100 V voltage rating, 121 mOhm ESR (where specified), and 10.00 mm lead spacing. Mechanical compatibility with snap-in mounting is preserved across all options.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with different physical dimensions? A: Yes. All listed substitutes maintain identical electrical specifications and lead spacing. Physical dimension variations reflect different manufacturer designs for the same snap-in mounting interface. Verify that the substitute fits within your application's mechanical envelope before selection.

Q: What is the significance of ESR matching? A: ESR (Equivalent Series Resistance) affects ripple current handling and heat generation. The ECO-S2AP222BA specifies 121 mOhm @ 120 Hz. All primary substitutes match this specification. The B41231A9228M000 does not specify ESR; contact the manufacturer for this parameter if ESR performance is critical to your application.

Q: Why does B41231A9228M000 have a lower thermal lifetime? A: B41231A9228M000 specifies 2000 Hrs @ 85°C compared to 3000 Hrs @ 85°C for other substitutes. This indicates a different thermal design. Select this part only if your application's thermal profile and expected service life are compatible with the lower rating.

Q: Are all substitutes RoHS compliant? A: Yes. All active substitute parts listed are ROHS3 compliant, providing regulatory compliance advantage over the obsolete ECO-S2AP222BA.

Q: Which substitute offers the best inventory availability? A: SLPX222M100E3P3 has the highest inventory level at 273,782 pieces in stock, followed by 380LX222M100K022 at 2,046 pieces. Inventory levels should be verified at the time of procurement.

Q: Can I interchange these parts without PCB modification? A: All substitutes maintain 10.00 mm lead spacing and snap-in mounting compatibility. No PCB modification is required. However, verify that the substitute's physical dimensions fit within your application's mechanical constraints, particularly if space is limited.
