Substitute Part Grouping Explanation

Substitution for the ECO-S1KA222EA is determined by strict electrical and mechanical compatibility. All substitute parts must meet the following criteria:

Mandatory Electrical Parameters:

Capacitance: 2200 µF
Tolerance: ±20%
Voltage Rating: 80 V
Operating Temperature: -40°C ~ 105°C
Lifetime: 3000 Hrs @ 105°C
Polarization: Polar

Mandatory Mechanical Parameters:

Mounting Type: Through Hole
Package Type: Radial, Can - Snap-In
Lead Spacing: 0.394" (10.00mm)

Substitute parts are categorized as follows:

Direct Equivalents maintain identical physical dimensions (1.378" diameter × 1.063" height) and electrical specifications, enabling direct board-level replacement without design modification.

Similar Equivalents maintain all electrical parameters and lead spacing but vary in physical dimensions (diameter and height). These require mechanical validation for fit within the application's physical constraints.

Parametric Equivalents satisfy all electrical and mechanical requirements but may exhibit variations in ESR or ripple current characteristics within acceptable operational ranges.

Engineering Selection Recommendations

Direct Replacement (No Design Modification Required):

381LX222M080A012 is the primary direct equivalent. It maintains identical physical dimensions (35.00 mm diameter × 27.00 mm height) and electrical specifications. This part is manufactured by Cornell Dubilier, carries active product status, and is ROHS3 compliant. Inventory availability is 1888 units.

228LMB080M2EC provides an alternative direct replacement with identical physical dimensions. Manufactured by Cornell Dubilier / Illinois Capacitor, this part is active and ROHS3 compliant with 786 units in stock. ESR is higher at 188.394 mOhm compared to the original 90 mOhm specification.

Conditional Replacement (Mechanical Validation Required):

381LX222M080J032, 381LX222M080K022, SLP222M080A7P3, SLP222M080C5P3, and SLP222M080E1P3 are electrically equivalent but feature different physical dimensions. These parts require verification that the alternative form factor fits within the application's physical constraints, including PCB layout, enclosure clearances, and thermal management considerations. All are active products with ROHS3 compliance.

381LX222M080H452 presents the most significant dimensional variation (22.00 mm diameter × 47.00 mm height) and should be selected only when space constraints specifically accommodate the taller profile.

All substitute parts maintain the required 80 V rating, 2200 µF capacitance, ±20% tolerance, 3000-hour lifetime at 105°C, and -40°C to 105°C operating temperature range. All are through-hole, radial snap-in packages with 10.00 mm lead spacing.

Frequently Asked Questions (FAQ)

Q: Can 381LX222M080A012 be used as a direct drop-in replacement for ECO-S1KA222EA?

A: Yes. The 381LX222M080A012 maintains identical physical dimensions (35.00 mm diameter × 27.00 mm height) and all required electrical parameters. No PCB layout or mechanical modifications are necessary.

Q: What is the difference between the 381LX series and SLP series substitutes?

A: Both series meet the core electrical requirements (2200 µF, 80 V, 3000 Hrs @ 105°C). The primary difference is ESR: 381LX parts do not specify ESR, while SLP parts specify 151 mOhm @ 120Hz. The original ECO-S1KA222EA specifies 90 mOhm @ 120Hz. SLP series parts are suitable where ESR specification is acceptable; 381LX parts require ESR verification if critical to application performance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All active substitute parts listed are ROHS3 compliant. The original ECO-S1KA222EA does not specify RoHS status due to its obsolete classification.

Q: Can I use SLP222M080E1P3 if my PCB has limited vertical clearance?

A: Yes. SLP222M080E1P3 has the lowest profile at 25.00 mm height compared to the original 27.00 mm. However, verify that the 30.00 mm diameter accommodates your PCB layout, as this dimension is larger than the original 35.00 mm diameter specification.

Q: What is the lead spacing for all substitute parts?

A: All substitute parts maintain 0.394" (10.00 mm) lead spacing, matching the original ECO-S1KA222EA. This ensures compatibility with existing PCB footprints.

Q: Which substitute offers the best inventory availability?

A: 381LX222M080H452 has the highest inventory at 3390 units. However, this part features non-standard dimensions (22.00 mm diameter × 47.00 mm height) and requires mechanical validation before selection.

Q: Is 228LMB080M2EC suitable for high-ripple-current applications?

A: 228LMB080M2EC specifies ripple current of 1.61 A @ 120 Hz and 2.0125 A @ 10 kHz. Compare these values against your application's ripple current requirements. The original ECO-S1KA222EA specifies 2.1 A @ 120 Hz and 2.415 A @ 100 kHz, indicating higher ripple current capability.
