227CKE100M Equivalent & Substitute Parts Reference

Part Overview

The 227CKE100M is a 220 µF, 100 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier / Illinois Capacitor. This component is classified as Active product status and is designed for bypass and decoupling applications. The part features a 603 mOhm equivalent series resistance at 120 Hz and supports a 2000-hour lifetime at 105°C operating temperature.

Substitute parts are necessary when the original 227CKE100M becomes unavailable, when extended component lifetime is required, or when enhanced ripple current handling is needed for specific circuit designs. All substitute parts listed maintain identical electrical ratings (220 µF, ±20% tolerance, 100 V rated voltage) and mechanical compatibility (radial, can package, 5.00 mm lead spacing, 12.50 mm diameter).

Engineering Selection Recommendations

Direct Equivalent (Same Lifetime Specification):

The ECA-2AHG221 from Panasonic Electronic Components is a direct functional equivalent to the 227CKE100M. Both parts specify 2000-hour lifetime at 105°C and maintain identical electrical ratings. The ECA-2AHG221 offers an extended operating temperature range (-55°C to 105°C versus -40°C to 105°C) and is ROHS3 compliant. Physical height differs by 0.5 mm (27.00 mm versus 26.50 mm), which must be verified for PCB clearance in space-constrained applications.

Upgraded Alternatives (Extended Lifetime):

The Rubycon YXJ, ZLH, and ZLJ series parts (100YXJ220M12.5X25, 100ZLH220MEFC12.5X25, 100ZLJ220M12.5X25) provide 10000-hour lifetime at 105°C, representing a five-fold increase in component reliability duration. These parts are suitable for applications requiring extended service life. The 100ZLJ220M12.5X25 offers the lowest impedance (47 mOhms) and highest ripple current capability (2.21 A @ 100 kHz) among Rubycon options. All three Rubycon parts have 27.00 mm seated height.

The Chemi-Con EKY-101ELL221MK25S and EKZN101ELL221MK25S series provide 10000-hour lifetime at 105°C with 26.50 mm seated height, matching the original part's physical profile. The EKZN101ELL221MK25S features the lowest impedance (38 mOhms) and highest ripple current capability (2.21 A @ 100 kHz) among all substitutes. Both Chemi-Con parts are ROHS3 compliant.

Automotive-Grade Alternative:

The EGPD101ELL221MK25H from Chemi-Con is an automotive-qualified part (AEC-Q200 rated) with extended operating temperature range (-40°C to 135°C). This part specifies 2000-hour lifetime at 135°C and maintains 26.50 mm seated height matching the original. The EGPD101ELL221MK25H is suitable for automotive and high-temperature applications.

All substitute parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements equivalent to the original 227CKE100M.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 227CKE100M with any of these parts without circuit redesign?

A: Yes, all listed substitute parts maintain identical electrical specifications (220 µF, ±20% tolerance, 100 V rating) and mechanical compatibility (radial, can package, 5.00 mm lead spacing, 12.50 mm diameter). Physical height differences of 0.5 mm must be verified for PCB clearance. No circuit redesign is required.

Q: What is the difference between direct equivalents and upgraded alternatives?

A: Direct equivalents (ECA-2AHG221) match the original 2000-hour lifetime specification at 105°C. Upgraded alternatives provide 10000-hour lifetime at 105°C (Rubycon YXJ, ZLH, ZLJ series and Chemi-Con EKY, EKZN series), extending component reliability by five times.

Q: What ripple current capability should I consider?

A: The original 227CKE100M supports 1.089 A ripple current at 100 kHz. The 100ZLJ220M12.5X25 and EKZN101ELL221MK25S both provide 2.21 A at 100 kHz, offering enhanced ripple current handling for high-frequency switching applications. The ECA-2AHG221 provides 660 mA at 100 kHz, which is lower than the original.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all substitute parts listed are ROHS3 compliant and REACH unaffected, meeting regulatory requirements equivalent to the original 227CKE100M.

Q: Can I use the EGPD101ELL221MK25H in non-automotive applications?

A: Yes, the EGPD101ELL221MK25H can be used in any application requiring the 220 µF, 100 V specification. The automotive qualification (AEC-Q200) indicates enhanced reliability and quality assurance, making it suitable for general-purpose, industrial, and consumer applications as well.

Q: What is the inventory availability of these substitute parts?

A: Inventory levels vary by part number. The EKY-101ELL221MK25S has the highest inventory at 1,000,400 pieces. The 100ZLJ220M12.5X25 has 157,232 pieces. The 100ZLH220MEFC12.5X25 has 12,400 pieces.
