CS65-B2GA221KYNKA Equivalent & Substitute Parts

Part Overview

The CS65-B2GA221KYNKA is a 220 pF ceramic capacitor rated for 300VAC/440VAC operation, manufactured by TDK Corporation. This high-voltage safety-rated component is designed for through-hole mounting in applications requiring X1, Y2 safety classifications. The part is currently active in production with ROHS3 compliance. Substitute parts are identified when inventory constraints, packaging requirements, or specific operational parameters necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CS65-B2GA221KYNKA is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 220 pF
• Tolerance: ±10%
• Temperature Coefficient: B
• Safety Ratings: X1, Y2
• Mounting Type: Through Hole
• Package Type: Radial, Disc
• Lead Spacing: 0.295" (7.50mm)
• RoHS Status: ROHS3 Compliant

Voltage Rating Compatibility: Substitute parts must meet or exceed the 300VAC/440VAC rating of the main part. Parts rated for 440VAC alone are acceptable substitutes for applications not requiring the dual 300VAC/440VAC specification.

Operating Temperature Range: The main part operates from -25°C to 125°C. Substitute parts with extended ranges (-55°C to 125°C) provide broader operational capability and are acceptable alternatives.

Packaging Format: The main part is supplied in Bulk packaging. Substitutes may be supplied in alternative packaging formats (Tape & Box) without affecting electrical or mechanical compatibility, provided all other parameters align.

Parameter Comparison

Engineering Selection Recommendations

CS65-B2GA221KANKA (MFR Recommended Substitute): This part is the manufacturer-recommended alternative. It maintains identical electrical specifications and physical dimensions to the main part while extending the operating temperature range to -55°C ~ 125°C. The addition of AEC-Q200 automotive qualification provides enhanced reliability documentation. Both parts are supplied in Bulk packaging and share the same lead spacing and form factor. This substitute is suitable for direct replacement in all applications where the main part is specified.

CS45-B2GA221K-NKA (Direct Substitute): This part meets all mandatory electrical parameters and safety ratings. The voltage rating of 440VAC satisfies applications requiring the 300VAC/440VAC specification of the main part. The primary differences are the reduced physical diameter (0.256" vs. 0.276") and Tape & Box packaging format. This substitute is electrically and mechanically compatible but requires verification of PCB layout clearances due to the smaller component body. The alternative packaging format may affect procurement and assembly workflows.

Frequently Asked Questions (FAQ)

Q: Can CS45-B2GA221K-NKA be used as a direct replacement for CS65-B2GA221KYNKA? A: Yes, from an electrical standpoint. Both parts share identical capacitance, tolerance, temperature coefficient, and safety ratings. The CS45 series has a smaller body diameter (6.50mm vs. 7.00mm), so PCB layout compatibility must be confirmed. Lead spacing remains identical at 0.295" (7.50mm).

Q: What is the difference between the 300VAC/440VAC rating and the 440VAC-only rating? A: The main part and CS65-B2GA221KANKA are rated for operation at both 300VAC and 440VAC. The CS45-B2GA221K-NKA is rated for 440VAC only. For applications operating at 300VAC, all three parts are suitable. For applications requiring dual-voltage capability documentation, the main part or CS65-B2GA221KANKA are preferred.

Q: Does the extended temperature range of CS65-B2GA221KANKA affect compatibility? A: No. The extended range (-55°C ~ 125°C vs. -25°C ~ 125°C) provides additional operational capability without compromising compatibility. This part is suitable for applications with wider temperature requirements.

Q: Are there packaging considerations when substituting with CS45-B2GA221K-NKA? A: Yes. The main part is supplied in Bulk packaging, while CS45-B2GA221K-NKA is supplied in Tape & Box format. This affects procurement quantities, storage, and automated assembly processes. Verify that your assembly line can accommodate tape-and-reel components if this substitute is selected.

Q: What does AEC-Q200 qualification on CS65-B2GA221KANKA indicate? A: AEC-Q200 is an automotive industry standard for passive component reliability. This certification indicates the part has undergone additional qualification testing for automotive applications. It does not affect electrical compatibility but provides enhanced reliability documentation for automotive or high-reliability applications.

Q: Are all three parts ROHS3 compliant? A: Yes. All three parts meet ROHS3 compliance requirements and are suitable for applications with RoHS restrictions.
