CK06BX223K Equivalent & Substitute Parts

Part Overview

The CK06BX223K is a 0.022 µF ±10% 100V ceramic capacitor with BX temperature coefficient, manufactured by Cornell Dubilier Electronics (CDE) in the Military MIL-C-11015 CK06 series. This radial through-hole component operates across -55°C to 125°C and is rated for high reliability applications. The product status is obsolete, making substitute parts necessary for ongoing production, repair, and maintenance activities.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict electrical and mechanical compatibility based on the following critical parameters:

Core Electrical Parameters:

Capacitance value: 0.022 µF (exact match required)
Rated voltage: Equal to or greater than 100V
Operating temperature range: -55°C ~ 125°C minimum (matching or exceeding required)
Tolerance: ±10% or tighter (±5% acceptable)

Mechanical Parameters:

Package type: Radial (through-hole)
Lead spacing: 0.200" (5.08mm) standard
Lead style: Formed leads
Height constraints: Maximum 0.300" to ensure PCB fit

All substitute parts listed maintain identical capacitance, voltage rating compatibility, temperature range, and through-hole radial package configuration. Temperature coefficient variants (C0G, NP0, X7R) are listed as substitutes because they meet all electrical and mechanical compatibility requirements for the specified application parameters.

Engineering Selection Recommendations

All listed KEMET substitutes maintain active product status and are ROHS3 compliant, providing long-term availability and regulatory compliance advantages over the obsolete CK06BX223K. The primary differentiation among substitutes lies in voltage rating and temperature coefficient type.

Direct Equivalent (100V Rating): C322C223K1G5TA, C322C223K1R5TA, and C323C223K1G5TA are electrically and mechanically equivalent at the specified 100V operating requirement. C322C223K1G5TA offers ±5% tolerance, while C322C223K1R5TA and C323C223K1G5TA maintain ±10% tolerance matching the original specification. C0G/NP0 temperature coefficient variants provide superior temperature stability compared to X7R.

Higher Voltage Ratings: C322C223K2G5TA, C322C223K2R5TA, C323C223K2G5TA, and C322C223KAG5TA are suitable for applications where higher voltage margins are required. These parts maintain identical capacitance and tolerance specifications with increased rated voltages of 200V, 200V, 200V, and 250V respectively.

Extreme Voltage Rating: C322C223KCR5TA provides 500V rating for high-voltage applications requiring maximum electrical stress margin.

All substitutes feature REACH unaffected status and identical operating temperature range (-55°C ~ 125°C) matching the original part specification.

Frequently Asked Questions (FAQ)

Q: Can I substitute C322C223K1R5TA (X7R) for the original CK06BX223K (BX)? A: Yes. Both parts are rated 0.022 µF ±10% at 100V with identical through-hole radial packages and lead spacing. The primary difference is temperature coefficient type. X7R provides wider capacitance stability across the operating temperature range compared to BX, making it electrically compatible.

Q: What is the difference between C0G, NP0, and X7R temperature coefficients? A: Temperature coefficient designates how capacitance changes across temperature. C0G/NP0 exhibits minimal capacitance drift across temperature and is preferred for precision circuits. X7R exhibits moderate capacitance variation but is acceptable for general-purpose applications. All three types maintain the specified capacitance at rated conditions.

Q: Why are 200V and 250V rated parts listed as substitutes for a 100V application? A: Higher voltage-rated capacitors are direct substitutes for lower voltage applications. The 0.022 µF capacitance and tolerance remain identical. Using a higher voltage-rated part provides additional electrical stress margin without affecting circuit performance. This practice is standard in component substitution.

Q: Is the height difference between 0.260" and 0.300" critical? A: Height differences must be evaluated against PCB layout constraints. The original CK06BX223K is 0.290" maximum height. C322C series parts are 0.260" (smaller), and C323C series parts are 0.300" (taller). Verify physical clearance in your specific design before selection.

Q: Are all KEMET substitutes RoHS compliant? A: Yes. All listed KEMET substitutes are ROHS3 compliant, exceeding RoHS requirements. The original CK06BX223K is RoHS non-compliant, making KEMET substitutes the necessary choice for RoHS-regulated applications.

Q: Can I use C322C223J1R5TA with ±5% tolerance where ±10% is specified? A: Yes. Tighter tolerance (±5%) is acceptable for applications specifying ±10%. The part meets or exceeds the original specification requirement.

Q: What is the inventory advantage of selecting KEMET alternatives? A: KEMET substitute parts range from 680 to 4737 pieces in stock, compared to 693 pieces of the obsolete CK06BX223K. This provides improved availability for immediate procurement and future requirements.
