Parameter Comparison

Engineering Selection Recommendations

CS45-B2GA331K-NKA (TDK Corporation): This substitute maintains identical electrical specifications to the main part with B temperature coefficient and equivalent safety ratings. The voltage rating of 440VAC exceeds the minimum 300VAC requirement. Both parts are manufactured by TDK Corporation and hold Active product status with ROHS3 compliance. Physical dimensions differ slightly (0.256" diameter versus 0.276" diameter), with lead spacing remaining constant at 0.295" (7.50mm). This part is suitable for direct substitution in applications where the reduced body diameter does not present mechanical constraints.

VY2331K29Y5SS63V7 (Vishay Beyschlag/Draloric/BC Components): This substitute provides equivalent capacitance, tolerance, and voltage rating with Y5S temperature coefficient. The operating temperature range extends to -40°C minimum, providing broader low-temperature performance compared to the B coefficient part. Lead spacing and safety ratings remain compatible. The body diameter is 0.295" (7.50mm) with seated height of 0.453" (11.50mm). This part is suitable for substitution in applications where extended low-temperature operation is required or where the larger body diameter accommodates board layout requirements.

Frequently Asked Questions (FAQ)

Q: Can CS45-B2GA331K-NKA replace CS70-B2GA331KYNKA in all applications?

A: CS45-B2GA331K-NKA maintains the same capacitance (330 pF), tolerance (±10%), temperature coefficient (B), and safety ratings (X1, Y2). The 440VAC voltage rating exceeds the 300VAC/440VAC specification of the main part. Lead spacing is identical at 0.295" (7.50mm). The primary difference is body diameter (0.256" versus 0.276"). Substitution is valid where board layout accommodates the smaller diameter.

Q: What is the difference between B and Y5S temperature coefficients?

A: Temperature coefficient designates how capacitance changes across the operating temperature range. B coefficient is specified for the CS70-B2GA331KYNKA and CS45-B2GA331K-NKA. Y5S coefficient is specified for VY2331K29Y5SS63V7. Both coefficients are acceptable for the X1, Y2 safety classification. Selection depends on application-specific temperature stability requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. CS70-B2GA331KYNKA, CS45-B2GA331K-NKA, and VY2331K29Y5SS63V7 are all ROHS3 Compliant with EAR99 classification.

Q: What is the significance of lead spacing in substitution?

A: Lead spacing of 0.295" (7.50mm) is maintained across all three parts. This parameter determines PCB hole pattern compatibility. Identical lead spacing ensures mechanical fit without board redesign.

Q: Can VY2331K29Y5SS63V7 be used in low-temperature applications?

A: VY2331K29Y5SS63V7 operates from -40°C to 125°C, extending the low-temperature range compared to the main part and CS45 substitute, which operate from -25°C to 125°C. This part is suitable for applications requiring operation below -25°C.
