Substitute Part Grouping Explanation

Substitution for the ECO-S2DA221BA is determined by the following critical parameters:

Capacitance: 220 µF (exact match required)
Tolerance: ±20% (exact match required)
Voltage Rating: 200 V minimum (equal or higher voltage acceptable)
Package / Case: Radial, Can - Snap-In (exact match required)
Lead Spacing: 0.394" (10.00 mm) (exact match required)
Size / Dimension: 0.866" Dia (22.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Operating Temperature Range: -40°C ~ 105°C (exact match required)

Substitute parts are grouped into two categories:

Direct Equivalents (200 V rated): Parts maintaining the original 200 V voltage specification with identical mechanical and electrical parameters.

Upgrade Substitutes (250 V rated): Parts with elevated voltage rating (250 V) that maintain all other critical parameters. These provide enhanced voltage margin while preserving form factor and thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can I use a 250 V rated capacitor in place of the 200 V ECO-S2DA221BA?

A: Yes. A 250 V rated capacitor is electrically compatible with a 200 V application. The higher voltage rating provides additional safety margin without affecting circuit performance. All upgrade substitutes listed maintain identical capacitance, tolerance, form factor, and thermal characteristics.

Q: What is the difference between the B43504 and B43508 series?

A: Both series maintain 220 µF capacitance and ±20% tolerance. B43504 series is rated at 200 V with 580 mOhm ESR @ 100 Hz. B43508 series is rated at 250 V with 530 mOhm ESR @ 100 Hz. Selection depends on circuit voltage requirements and ESR performance needs.

Q: Does the slight height increase in B43504E2227M80 and B43504E2227M87 affect mounting?

A: The height increase from 1.063" to 1.071" (27.00 mm to 27.20 mm) is 0.008" and remains within standard through-hole mounting tolerances. No mechanical redesign is required for PCB layout or enclosure clearance in typical applications.

Q: Why does LGR2D221MELZ25 have a 10000-hour lifetime specification?

A: LGR2D221MELZ25 from Nichicon is engineered for extended operational life. The 10000-hour rating at 105°C provides enhanced reliability for applications requiring longer service intervals or higher availability requirements compared to the standard 3000-hour specification.

Q: Are all substitute parts ROHS3 compliant?

A: All active substitute parts listed are ROHS3 compliant. The original ECO-S2DA221BA is obsolete with unspecified RoHS status. Substitution with ROHS3-compliant alternatives ensures compliance with current environmental and regulatory standards.

Q: Can I mix different substitute part numbers in the same design?

A: Yes, provided all selected parts meet the circuit's voltage, capacitance, and thermal requirements. All listed substitutes maintain identical capacitance (220 µF), tolerance (±20%), form factor, and lead spacing (0.394" / 10.00 mm), ensuring functional interchangeability within the same PCB design.
