Substitute Part Grouping Explanation

Substitution eligibility for the ECO-S2HP221DA is determined by the following mandatory parameters:

Capacitance: 220 µF (exact match required)
Voltage - Rated: 500 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Package / Case: Radial, Can - Snap-In (exact match required)
Mounting Type: Through Hole (exact match required)
Lead Spacing: 0.394" (10.00 mm) (exact match required)
Operating Temperature Range: -25°C ~ 85°C (exact match required)
Lifetime @ Temperature: 3000 Hrs @ 85°C (exact match required)

All substitute parts listed below meet these core electrical and mechanical requirements. Variations in ESR, ripple current ratings, and physical dimensions (diameter and height) are permitted within the snap-in package category, provided the lead spacing and mounting footprint remain compatible.

Engineering Selection Recommendations

All four Cornell Dubilier Electronics 380LX series parts are active products with ROHS3 compliance and REACH unaffected status, providing regulatory advantage over the obsolete Panasonic ECO-S2HP221DA.

380LX221M500K452: Parametric equivalent with identical ESR (754 mOhm @ 120 Hz), ripple current rating (1.5 A @ 120 Hz), and physical dimensions (1.181" diameter, 1.772" height) to the original part. This is the closest functional match for direct replacement in existing designs.

380LX221M500A032: Meets all core electrical parameters with identical ESR (754 mOhm). Physical dimensions differ with larger diameter (1.378") and reduced height (1.378"), suitable for applications where vertical space is constrained.

380LX221M500A042: Acceptable substitute with higher ESR (915 mOhm @ 120 Hz) and increased ripple current capability (1.9 A @ 120 Hz, 2.5 A @ 20 kHz). Physical dimensions are 1.378" diameter and 1.654" height. Selection depends on circuit ripple current requirements.

380LX221M500K052: Acceptable substitute with lower ESR (654 mOhm @ 120 Hz) and highest ripple current capability (2 A @ 120 Hz, 2.7 A @ 20 kHz). Physical dimensions are 1.181" diameter and 2.047" height, requiring additional vertical clearance.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the ECO-S2HP221DA?

A: All four substitute parts meet the mandatory electrical and mechanical parameters (220 µF, 500 V, ±20% tolerance, 3000 Hrs @ 85°C, -25°C ~ 85°C operating range, 0.394" lead spacing, radial snap-in package). Physical dimensions vary; verify available board space before selection.

Q: What is the difference between the 380LX221M500K452 and other 380LX variants?

A: The 380LX221M500K452 provides the closest match to the original ECO-S2HP221DA with identical ESR (754 mOhm), ripple current (1.5 A @ 120 Hz), and physical dimensions (1.181" diameter, 1.772" height). Other variants offer different ESR values and physical sizes to accommodate specific design constraints.

Q: Does ESR variation affect circuit performance?

A: ESR affects voltage ripple, heat dissipation, and transient response. The 380LX221M500K052 has the lowest ESR (654 mOhm), while the 380LX221M500A042 has the highest (915 mOhm). Selection should align with circuit ripple current requirements and thermal management capabilities.

Q: Are all substitute parts RoHS compliant?

A: Yes. All four Cornell Dubilier Electronics 380LX series parts are ROHS3 compliant and REACH unaffected, providing regulatory compliance advantage over the obsolete Panasonic part.

Q: What is the lead spacing requirement?

A: All parts, including the original and substitutes, have 0.394" (10.00 mm) lead spacing for snap-in mounting. This ensures PCB footprint compatibility across all options.

Q: Which substitute should I choose for space-constrained applications?

A: The 380LX221M500A032 offers the smallest height (1.378") among options with larger diameter (1.378"). The 380LX221M500K452 maintains the original dimensions (1.181" diameter, 1.772" height) and is recommended for direct replacement without layout modifications.
