Substitute Part Grouping Explanation

Substitution eligibility for the ECO-S2HP221EA is determined by strict adherence to the following parameters:

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

All substitute parts listed below meet these core electrical and mechanical parameters. Variations in ESR, ripple current ratings, case diameter, and height are documented but do not disqualify substitution when the above criteria are satisfied.

Parameter Comparison

Engineering Selection Recommendations

All four Cornell Dubilier Electronics 380LX series parts (380LX221M500A042, 380LX221M500K052, 380LX221M500K452, 380LX221M500A032) meet the core electrical and mechanical substitution criteria for the obsolete ECO-S2HP221EA.

380LX221M500A032 and 380LX221M500K452 are preferred for applications requiring minimal form factor changes, as both maintain the original 1.378" (35.00 mm) case diameter and 1.378" (35.00 mm) height of the ECO-S2HP221EA. The 380LX221M500A032 provides an exact dimensional match.

380LX221M500K052 offers the lowest ESR at 654 mOhm @ 120 Hz, suitable for applications prioritizing reduced impedance. However, this part features a smaller case diameter of 1.181" (30.00 mm) and increased height of 2.047" (52.00 mm), requiring PCB layout verification.

380LX221M500A042 presents a mid-range ESR of 915 mOhm @ 120 Hz with a case diameter matching the original part but increased height of 1.654" (42.00 mm).

All substitute parts carry active product status, ROHS3 compliance, and REACH unaffected designation, supporting long-term supply chain continuity and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the ECO-S2HP221EA?

A: All four substitute parts meet the core electrical and mechanical parameters (220 µF, 500 V, ±20% tolerance, 3000 Hrs @ 85°C, through-hole radial snap-in package, 10.00 mm lead spacing). However, physical dimensions vary. Verify PCB layout clearance before substitution, particularly for 380LX221M500K052 and 380LX221M500K452, which have reduced case diameters.

Q: What is the significance of ESR differences among the substitute parts?

A: ESR (Equivalent Series Resistance) affects ripple current handling and thermal performance. Lower ESR values (380LX221M500K052 at 654 mOhm) reduce heat generation under AC ripple conditions. Higher ESR values (380LX221M500A042 at 915 mOhm) may require thermal management review in high-ripple applications. The ECO-S2HP221EA and 380LX221M500K452/380LX221M500A032 share identical ESR at 754 mOhm.

Q: Are there compliance or supply chain advantages to selecting one substitute over another?

A: All substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory standards. All carry active product status from Cornell Dubilier Electronics, ensuring long-term availability. Selection should prioritize dimensional compatibility with existing PCB designs.

Q: What happens if the substitute part has a different height than the original?

A: Height variations affect PCB clearance and mechanical fit within enclosures. The 380LX221M500A032 maintains the original 1.378" (35.00 mm) height. Parts with increased heights (380LX221M500A042, 380LX221M500K052, 380LX221M500K452) require verification that component clearance to adjacent circuitry and enclosure lids is maintained.

Q: Can I use 380LX221M500K052 if my PCB has limited vertical space?

A: No. The 380LX221M500K052 has a height of 2.047" (52.00 mm), the tallest among the substitutes. If vertical clearance is constrained, select 380LX221M500A032 (1.378" height) or 380LX221M500K452 (1.772" height) instead.
