Substitute Part Grouping Explanation

Substitute parts for the ECO-S1KP222BA are classified based on strict electrical and mechanical parameter alignment:

Direct Substitutes maintain identical or equivalent electrical performance and physical dimensions:

Capacitance: 2200 µF (exact match required)
Voltage Rating: 80 V (exact match required)
Tolerance: ±20% (exact match required)
Lead Spacing: 0.394" (10.00 mm) (exact match required)
Package Type: Radial, Can - Snap-In (exact match required)
Mounting Type: Through Hole (exact match required)

Similar Parts share core electrical specifications but differ in physical dimensions or thermal performance characteristics. These parts are suitable only when mechanical envelope constraints permit variation.

Parametric Equivalents match all critical electrical parameters and primary dimensions while maintaining functional compatibility within the specified operating range.

Engineering Selection Recommendations

Direct Replacement (Identical Footprint and Performance): SLP222M080A7P3 and SLPX222M080A7P3 are parametric equivalents matching the original ECO-S1KP222BA in case diameter (0.866" / 22.00 mm) and height (1.575" / 40.00 mm). Both are manufactured by Cornell Dubilier Electronics with active product status and RoHS3 compliance. SLP222M080A7P3 extends operating temperature to 105°C with 3000-hour lifetime at that temperature. SLPX222M080A7P3 maintains the -40°C to 85°C range with 3000-hour lifetime at 85°C.

Active Manufacturer Alternative: B41231A228M from EPCOS - TDK Electronics maintains identical electrical specifications (2200 µF, 80 V, ±20% tolerance) with active product status and RoHS3 compliance. Height is reduced to 1.457" (37.00 mm), requiring verification of available board space. Lifetime is 2000 hours at 85°C, lower than the original specification.

Space-Constrained Applications: SLPX222M080C3P3 and SLPX222M080E1P3 provide active alternatives with identical electrical parameters but different physical envelopes. Both feature case diameters of 0.984" to 1.181" and heights of 0.984" to 1.181", suitable only when the original 0.866" × 1.575" footprint cannot be accommodated.

Mechanical Constraint Exception: 380LX222M080A202 features a larger case diameter (1.378" / 35.00 mm) with reduced height (0.866" / 22.00 mm). This configuration is applicable only in designs where horizontal space is available and vertical clearance is limited.

Frequently Asked Questions (FAQ)

Q: Can SLPX222M080A7P3 directly replace ECO-S1KP222BA without board modification? A: Yes. SLPX222M080A7P3 maintains identical case diameter (0.866" / 22.00 mm), height (1.575" / 40.00 mm), and lead spacing (0.394" / 10.00 mm). No PCB layout changes are required.

Q: What is the difference between SLP222M080A7P3 and SLPX222M080A7P3? A: Both parts share identical electrical specifications and physical dimensions. SLP222M080A7P3 operates to 105°C with 3000-hour lifetime at that temperature, while SLPX222M080A7P3 operates to 85°C. Selection depends on thermal environment requirements.

Q: Why does B41231A228M have a shorter height? A: B41231A228M is designed with a different internal construction, resulting in 1.457" (37.00 mm) height versus 1.575" (40.00 mm) for the original. Verify available vertical clearance before selection.

Q: Are all substitute parts RoHS compliant? A: EPCOS B41231A228M and all Cornell Dubilier parts (SLP222M080A7P3, SLPX222M080A7P3, SLPX222M080C3P3, SLPX222M080E1P3, 380LX222M080A202) are RoHS3 compliant. The original ECO-S1KP222BA is obsolete and compliance status is not applicable.

Q: Can I use SLPX222M080C3P3 or SLPX222M080E1P3 as direct replacements? A: These parts have identical electrical specifications but different physical dimensions. SLPX222M080C3P3 measures 0.984" diameter × 1.181" height; SLPX222M080E1P3 measures 1.181" diameter × 0.984" height. Use only if PCB layout permits the different footprint.

Q: What is the inventory status of substitute parts? A: SLPX222M080C3P3 has the highest availability at 6765 pieces. SLP222M080A7P3 and SLPX222M080A7P3 have 628 and 1139 pieces respectively. B41231A228M has 1725 pieces. Verify current stock with your supplier.

Q: Does the ESR specification affect part selection? A: ESR values range from 121 mOhm (original) to 151 mOhm (SLPX series) to 135 mOhm (380LX series). Selection depends on ripple current handling requirements. Lower ESR reduces heat generation in high
