CD75-B2GA331KYNKA Equivalent & Substitute Parts

Part Overview

The CD75-B2GA331KYNKA is a 330 pF ceramic capacitor rated for 440VAC operation, manufactured by TDK Corporation. This high-voltage safety-rated component (X1, Y1) is designed for through-hole mounting in applications requiring reliable AC voltage suppression and filtering. The part is currently active in production with ROHS3 compliance and maintains a temperature coefficient of B across an operating range of -25°C to 125°C. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the allowed parameter tolerances for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD75-B2GA331KYNKA is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance value: 330 pF
• Tolerance: ±10%
• Safety ratings: X1, Y1
• Mounting type: Through Hole
• Package type: Radial, Disc
• Lead style: Formed Leads - Kinked
• RoHS compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Voltage rating: Equal to or greater than 440VAC
• Temperature coefficient: May differ (B or Y5S acceptable)
• Operating temperature range: May extend beyond -25°C to 125°C
• Physical dimensions: Minor variations permitted within lead spacing tolerance of 0.394" (10.00mm)
• Manufacturer: Different manufacturers acceptable if all mandatory parameters match

Two substitute parts meet these criteria: CD45-B2GA331K-NKA (TDK Corporation) and VY1331K31Y5SQ63V0 (Vishay Beyschlag/Draloric/BC Components).

Parameter Comparison

Engineering Selection Recommendations

CD45-B2GA331K-NKA (TDK Corporation): This substitute maintains identical electrical specifications to the main part with matching 440VAC rating, ±10% tolerance, and B temperature coefficient. Both parts are manufactured by TDK Corporation and carry ROHS3 compliance. The primary difference is the reduced upper operating temperature limit (85°C versus 125°C) and slightly smaller physical dimensions (7.00mm diameter versus 7.50mm). This substitute is suitable for applications where the thermal environment does not exceed 85°C. Inventory availability is higher at 1861 pieces.

VY1331K31Y5SQ63V0 (Vishay Beyschlag/Draloric/BC Components): This substitute provides a higher voltage rating of 760VAC, exceeding the 440VAC requirement of the main part. The temperature coefficient differs (Y5S versus B) and the operating range extends to -40°C at the lower end with 125°C upper limit maintained. Physical dimensions are slightly larger (8.00mm diameter, 12.00mm height). This substitute is suitable for applications requiring enhanced voltage margin or extended low-temperature operation. Inventory availability is significantly higher at 25,969 pieces.

Both substitutes maintain the critical safety ratings (X1, Y1), through-hole mounting configuration, radial disc package type, and kinked lead style. Selection between substitutes depends on specific thermal and voltage requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can CD45-B2GA331K-NKA be used as a direct replacement for CD75-B2GA331KYNKA?

A: Yes, for applications operating at or below 85°C ambient temperature. Both parts share identical capacitance (330 pF), tolerance (±10%), voltage rating (440VAC), temperature coefficient (B), and safety certifications (X1, Y1). The reduced upper operating temperature limit of CD45-B2GA331K-NKA is the only functional constraint.

Q: What is the advantage of using VY1331K31Y5SQ63V0 over the main part?

A: VY1331K31Y5SQ63V0 provides a 760VAC voltage rating compared to 440VAC, offering additional voltage margin in high-voltage applications. It also extends the lower operating temperature to -40°C. The temperature coefficient differs (Y5S versus B), which may affect capacitance stability across temperature ranges depending on application requirements.

Q: Are all three parts physically interchangeable on a PCB?

A: Lead spacing is identical at 0.394" (10.00mm) for all three parts, ensuring PCB footprint compatibility. Physical dimensions vary slightly: CD75-B2GA331KYNKA (7.50mm diameter), CD45-B2GA331K-NKA (7.00mm diameter), and VY1331K31Y5SQ63V0 (8.00mm diameter). Verify clearance in the target application before substitution.

Q: Do all substitute parts maintain the same safety certifications?

A: Yes. All three parts carry X1 and Y1 safety ratings and ROHS3 compliance, meeting the same regulatory requirements for high-voltage safety applications.

Q: Which substitute has better inventory availability?

A: VY1331K31Y5SQ63V0 has the highest inventory at 25,969 pieces, followed by CD45-B2GA331K-NKA at 1,861 pieces, compared to the main part at 925 pieces.
