Equivalent & Substitute Parts: 228CKE010MLQ

Part Overview

The 228CKE010MLQ is a 2200 µF, 10 V aluminum electrolytic capacitor manufactured by Cornell Dubilier / Illinois Capacitor in the CKE series. This radial, through-hole component is rated for bypass and decoupling applications with a 2000-hour lifetime at 105°C. The product is active and ROHS3 compliant, making it suitable for applications requiring long-term reliability in electronic circuits where capacitive energy storage and voltage regulation are essential functions.

Substitute parts are necessary to address component availability, procurement lead times, or inventory constraints while maintaining electrical and mechanical compatibility with the original design specification.

Engineering Selection Recommendations

All three capacitor options (228CKE010MLQ, 10PX2200MEFC10X16, and EEU-HD1A222) are Active products with ROHS3 compliance and REACH unaffected status. Selection between these parts may be determined by:

Procurement Availability: Verify current inventory status through authorized distributors. The Rubycon 10PX2200MEFC10X16 offers the highest available inventory (7579 units), while the Panasonic EEU-HD1A222 provides 1196 units and the Cornell Dubilier 228CKE010MLQ provides 1050 units.

Operating Temperature Range: Both substitute parts (Rubycon and Panasonic) extend the lower operating limit to -55°C compared to the original part's -40°C minimum, providing enhanced cold-temperature performance when required.

Ripple Current Performance: The Rubycon 10PX2200MEFC10X16 provides the highest ripple current ratings at both low and high frequencies (860 mA @ 120 Hz, 989 mA @ 10 kHz), offering additional thermal margin in ripple-current-limited applications.

Moisture Sensitivity: The Panasonic EEU-HD1A222 specifies MSL 1 (Unlimited), while the original part and Rubycon substitute list MSL as Not Applicable, indicating no moisture sensitivity constraints.

Frequently Asked Questions (FAQ)

Q: Can 10PX2200MEFC10X16 directly replace 228CKE010MLQ on a PCB?

A: Yes. Both parts share identical capacitance (2200 µF), voltage rating (10 V), lead spacing (5.00 mm), diameter (10.00 mm), and height (17.50 mm). Both are through-hole radial cans requiring no circuit redesign or PCB modification.

Q: What is the difference between the substitute parts?

A: The Rubycon 10PX2200MEFC10X16 and Panasonic EEU-HD1A222 both meet all electrical and mechanical specifications. The Rubycon variant offers higher ripple current ratings, while the Panasonic variant specifies MSL 1 moisture sensitivity. Operating temperature ranges extend to -55°C for both substitutes versus -40°C for the original part.

Q: Are all three capacitors ROHS3 compliant?

A: Yes. The 228CKE010MLQ (Cornell Dubilier), 10PX2200MEFC10X16 (Rubycon), and EEU-HD1A222 (Panasonic) are all ROHS3 compliant and REACH unaffected, meeting regulatory requirements for electronic component procurement.

Q: What determines a valid substitute for this capacitor?

A: Valid substitutes must maintain the same capacitance value (2200 µF), voltage rating (10 V), tolerance (±20%), lead spacing (5.00 mm), physical dimensions, through-hole mounting configuration, and minimum 2000-hour lifetime at 105°C. Electrical performance parameters such as ESR and ripple current may vary without affecting functional compatibility.

Q: How should I select between available substitutes?

A: Selection depends on component availability, lead time requirements, and application-specific performance criteria. Verify procurement lead times, inventory levels, and ripple current requirements. Both substitutes are functionally equivalent for standard bypass and decoupling applications.
