Substitute Part Grouping Explanation

Substitution of the ECO-S2DP221BA 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 ratings are acceptable)
Package / Case: Radial, Can - Snap-In (exact match required)
Lead Spacing: 0.394" (10.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Physical Dimensions: 0.866" Dia (22.00 mm) and height up to 0.984" (25.00 mm) (exact match required)
Polarization: Polar (exact match required)

Substitute parts are categorized as either upgrade substitutes (higher voltage rating or improved thermal performance) or parametric equivalents (matching all critical electrical and mechanical specifications).

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher voltage rating than the original ECO-S2DP221BA?

A: Yes. A higher voltage rating (250 V vs. 200 V) is electrically compatible and provides additional safety margin. The capacitor will function correctly in circuits designed for 200 V operation.

Q: What is the difference between upgrade substitutes and parametric equivalents?

A: Upgrade substitutes offer improvements such as higher voltage ratings or extended operating temperature ranges while maintaining core electrical specifications. Parametric equivalents match all critical electrical and mechanical parameters of the original part.

Q: Does the physical height difference of 381LX221M200H012 affect compatibility?

A: The 381LX221M200H012 has a maximum seated height of 1.063" (27.00 mm) compared to the original 0.984" (25.00 mm). Verify available PCB clearance and component placement before selection.

Q: Are all substitute parts RoHS3 compliant?

A: All active substitute parts listed are RoHS3 compliant. The original ECO-S2DP221BA is obsolete and does not carry RoHS3 certification.

Q: Which substitute offers the lowest ESR?

A: The 227LBB250M2BC and 227LBB200M2BC both provide 754.67 mOhm ESR at 120 Hz, lower than the original 829 mOhm specification.

Q: Can I substitute based on capacitance and voltage alone?

A: No. Package type, lead spacing, physical dimensions, and mounting configuration must match exactly. All listed substitutes maintain the radial, can snap-in package with 0.394" (10.00 mm) lead spacing and 0.866" (22.00 mm) diameter.
