Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CS65-B2GA221KYVKA is determined by the following critical parameters:

• Capacitance Value: Must be 220 pF ±10%
• Temperature Coefficient: Must be B
• Safety Ratings: Must maintain X1, Y2 classification
• Mounting Configuration: Must be Through Hole with Radial, Disc package
• Lead Compatibility: Must use Formed Leads - Kinked style
• Voltage Rating: Must support minimum 300VAC operation; 440VAC rating is acceptable as an upgrade
• Operating Temperature: Must support -25°C ~ 125°C range
• Compliance: Must maintain ROHS3 compliance

The CS45-B2GA221K-VKA meets all substitution criteria with identical capacitance, tolerance, temperature coefficient, safety ratings, mounting type, and lead style. The voltage rating of 440VAC exceeds the minimum 300VAC requirement, making this part suitable for direct substitution in applications requiring the CS65-B2GA221KYVKA.

Parameter Comparison

Engineering Selection Recommendations

Both the CS65-B2GA221KYVKA and CS45-B2GA221K-VKA are active production components from TDK Corporation with ROHS3 compliance. The CS45-B2GA221K-VKA is a valid substitute based on matching electrical specifications and safety ratings. The substitute part features a slightly smaller body diameter (6.50mm vs 7.00mm) while maintaining identical lead spacing (7.50mm), which ensures PCB footprint compatibility. The 440VAC voltage rating of the substitute exceeds the 300VAC/440VAC rating of the main part, providing equivalent or superior performance in high-voltage safety applications. Both parts are classified as X1, Y2 safety-rated components suitable for the same application domains.

Frequently Asked Questions (FAQ)

Q: Can the CS45-B2GA221K-VKA be used as a direct replacement for the CS65-B2GA221KYVKA?

A: Yes. Both parts share identical capacitance (220 pF), tolerance (±10%), temperature coefficient (B), safety ratings (X1, Y2), operating temperature range (-25°C ~ 125°C), mounting type (Through Hole), package configuration (Radial, Disc), and lead style (Formed Leads - Kinked). The substitute's 440VAC rating meets or exceeds the main part's 300VAC/440VAC requirement.

Q: Are there physical dimension differences between these parts?

A: The CS45-B2GA221K-VKA has a slightly smaller body diameter (6.50mm) compared to the CS65-B2GA221KYVKA (7.00mm). However, lead spacing is identical at 7.50mm, ensuring compatibility with existing PCB layouts designed for the main part.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the CS65-B2GA221KYVKA and CS45-B2GA221K-VKA are ROHS3 compliant and maintain X1, Y2 safety ratings for high-voltage applications.

Q: What determines whether a part can substitute for the CS65-B2GA221KYVKA?

A: Substitution requires matching capacitance value (220 pF ±10%), temperature coefficient (B), safety ratings (X1, Y2), mounting type (Through Hole), package style (Radial, Disc), lead configuration (Formed Leads - Kinked), and operating temperature range (-25°C ~ 125°C). Voltage rating must support minimum 300VAC operation.

Q: Is the higher voltage rating of the substitute part a concern?

A: No. A higher voltage rating (440VAC) is acceptable in applications designed for 300VAC/440VAC operation. The substitute provides equivalent or improved performance characteristics.
