CS75-B2GA471KYGKA Equivalent & Substitute Parts

Part Overview

The CS75-B2GA471KYGKA is a 470 pF ceramic capacitor manufactured by TDK Corporation, rated for 300VAC/440VAC operation with B temperature coefficient. This component is classified as a safety-rated capacitor (X1, Y2) designed for high-voltage applications requiring through-hole radial mounting. The part is currently active in production with ROHS3 compliance and is suitable for applications demanding reliable AC voltage suppression and filtering in safety-critical circuits.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CS75-B2GA471KYGKA is determined by strict equivalence across the following critical parameters:

• Capacitance Value: Must be 470 pF ±10%
• Voltage Rating: Must support minimum 300VAC operation; 440VAC rated parts are acceptable as higher-rated alternatives
• Safety Certifications: Must maintain X1, Y2 ratings for safety-critical applications
• Mounting Configuration: Must be through-hole radial with formed kinked leads
• RoHS Compliance: Must meet ROHS3 standard
• Package Dimensions: Lead spacing of 0.295" (7.50mm) is required for PCB compatibility

Two substitute parts meet these criteria: CS45-B2GA471K-NKA (TDK Corporation) and VY2471K29Y5SS63V7 (Vishay Beyschlag/Draloric/BC Components). Both maintain the required capacitance, safety ratings, and mechanical compatibility while offering alternative temperature coefficient specifications and voltage ratings.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain full compliance with the electrical and mechanical requirements of the CS75-B2GA471KYGKA. Selection between alternatives should be based on the following factors:

CS45-B2GA471K-NKA: This TDK Corporation substitute shares identical temperature coefficient (B) and operating temperature range with the main part. It reduces the voltage rating to 440VAC, which remains suitable for applications not requiring the dual 300VAC/440VAC specification. This part offers the closest functional equivalence to the original specification.

VY2471K29Y5SS63V7: This Vishay substitute maintains 440VAC voltage rating and extends the lower operating temperature limit to -40°C through its Y5S temperature coefficient. This part is appropriate for applications requiring enhanced low-temperature performance while maintaining all safety certifications and mechanical compatibility.

Both parts are active products with ROHS3 compliance and current production status, ensuring long-term availability and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can CS45-B2GA471K-NKA be used in place of CS75-B2GA471KYGKA?

A: Yes. Both parts share 470 pF capacitance, ±10% tolerance, B temperature coefficient, identical operating temperature range (-25°C ~ 125°C), X1/Y2 safety ratings, and 0.295" lead spacing. The CS45 variant is rated for 440VAC, which is acceptable for circuits designed for 300VAC/440VAC operation.

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

A: Temperature coefficient designates the capacitance change over the operating temperature range. B coefficient indicates standard stability across -25°C to 125°C. Y5S coefficient provides extended low-temperature performance to -40°C while maintaining the same upper limit. Selection depends on the minimum operating temperature requirement of the application.

Q: Are all three parts mechanically interchangeable?

A: Yes. All three parts feature 0.295" (7.50mm) lead spacing, radial disc package configuration, and formed kinked leads. PCB footprints designed for the CS75-B2GA471KYGKA will accommodate both substitute parts without modification.

Q: Do the substitute parts maintain safety certifications?

A: Yes. Both CS45-B2GA471K-NKA and VY2471K29Y5SS63V7 carry X1 and Y2 safety ratings, meeting the same regulatory requirements as the original part for safety-critical applications.

Q: What is the voltage rating difference between the main part and substitutes?

A: The CS75-B2GA471KYGKA is dual-rated for 300VAC/440VAC. Both substitutes are rated for 440VAC only. For applications operating exclusively at 440VAC or below, either substitute is suitable. Applications requiring 300VAC operation should confirm that 440VAC-rated components meet circuit design margins.
