CD75-B2GA331KYGKA Equivalent & Substitute Parts

Part Overview

The CD75-B2GA331KYGKA is a 330 pF ceramic capacitor manufactured by TDK Corporation, rated for 440VAC operation with B temperature coefficient. This component is designed for safety-critical applications requiring high voltage ceramic capacitors with radial, disc configuration and through-hole mounting. The part is currently active in production with full RoHS3 compliance. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and safety ratings can be maintained across alternative manufacturers while meeting application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD75-B2GA331KYGKA is determined by the following critical parameters:

• Capacitance Value: Must be 330 pF ±10%
• Safety Ratings: Must maintain X1, Y1 classification for safety-critical applications
• Mounting Configuration: Through-hole radial disc package with formed kinked leads
• Lead Spacing: 0.394" (10.00mm) standard spacing for PCB compatibility
• Voltage Rating: Must equal or exceed 440VAC nominal rating
• Temperature Coefficient: B or equivalent performance across -25°C ~ 125°C operating range
• Compliance: RoHS3 compliant status required

The substitute part VY1331K31Y5SQ63V0 meets these criteria with a higher voltage rating (760VAC) and extended lower temperature limit (-40°C), providing enhanced performance margins while maintaining identical capacitance, tolerance, safety ratings, and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the CD75-B2GA331KYGKA and VY1331K31Y5SQ63V0 are active production components with full RoHS3 compliance and identical safety certifications (X1, Y1 ratings). Selection between these parts should be based on:

Primary Selection (CD75-B2GA331KYGKA): Use when TDK supply chain preference is established or when the 440VAC rating precisely matches application voltage specifications with no margin requirement.

Substitute Selection (VY1331K31Y5SQ63V0): Use when Vishay component availability is preferred, when higher voltage margin (760VAC vs 440VAC) provides design robustness, or when extended lower temperature operation (-40°C vs -25°C) is required. Physical dimensions are compatible with standard PCB layouts designed for the primary part.

Both components satisfy safety-critical application requirements and maintain equivalent electrical performance at the specified 330 pF capacitance value with ±10% tolerance.

Frequently Asked Questions (FAQ)

Q: Can VY1331K31Y5SQ63V0 be used as a direct replacement for CD75-B2GA331KYGKA?

A: Yes. Both parts share identical capacitance (330 pF), tolerance (±10%), safety ratings (X1, Y1), lead spacing (10.00mm), and mounting configuration (through-hole radial disc). The substitute part exceeds the voltage requirement (760VAC vs 440VAC) and extends the lower operating temperature limit (-40°C vs -25°C), making it functionally compatible for the same applications.

Q: What are the physical dimension differences?

A: The CD75-B2GA331KYGKA has a 0.295" (7.50mm) diameter body with 0.453" (11.50mm) seated height. The VY1331K31Y5SQ63V0 has a 0.315" (8.00mm) diameter body with 0.472" (12.00mm) seated height. Both maintain the same 0.394" (10.00mm) lead spacing. Verify PCB layout clearance before substitution if space constraints exist.

Q: Are both parts RoHS3 compliant?

A: Yes. Both CD75-B2GA331KYGKA and VY1331K31Y5SQ63V0 are RoHS3 compliant and suitable for applications requiring environmental compliance certification.

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

A: Both temperature coefficients are suitable for the specified -25°C ~ 125°C (primary part) and -40°C ~ 125°C (substitute part) operating ranges. The substitute part's Y5S coefficient with extended lower temperature range provides additional operational margin in cold environments.

Q: Can these parts be used interchangeably in safety-critical circuits?

A: Yes. Both parts carry identical X1, Y1 safety ratings, indicating suitability for safety-critical applications. The substitute part's higher voltage rating (760VAC) provides additional safety margin beyond the 440VAC requirement.
