Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD75-B2GA331KYVKA is determined by the following critical parameters:

Primary Matching Criteria:

• Capacitance value: 330 pF
• Tolerance: ±10%
• Safety ratings: X1, Y1
• Mounting type: Through Hole, Radial configuration
• Lead spacing: 0.394" (10.00mm)
• RoHS compliance: ROHS3 Compliant

Allowable Variations:

• Voltage rating: Equal to or greater than 440VAC
• Temperature coefficient: May differ (B, Y5S acceptable for safety-rated applications)
• Operating temperature range: May extend beyond -25°C ~ 125°C
• Physical dimensions: Minor variations acceptable if lead spacing and mounting footprint remain compatible
• Packaging format: Original or Cut Tape acceptable

Two substitute parts meet these criteria and are listed below.

Parameter Comparison

Engineering Selection Recommendations

CD45-B2GA331K-VKA (TDK Corporation)

This substitute is manufactured by the same supplier as the original part and maintains identical electrical specifications: 330 pF capacitance, ±10% tolerance, 440VAC rating, and B temperature coefficient. The part is currently in active production status with 2269 units in stock. It carries ROHS3 compliance and MSL rating of 1 (Unlimited), indicating superior moisture resistance. The operating temperature range is reduced to -25°C ~ 85°C compared to the original specification. Physical dimensions are specified (0.276" diameter, 0.433" height), and lead spacing remains at 0.394" (10.00mm), ensuring direct footprint compatibility. This option is recommended for applications requiring exact electrical parameter matching with assured supply availability.

VY1331K31Y5SQ6UV0 (Vishay Beyschlag/Draloric/BC Components)

This substitute provides enhanced voltage rating at 760VAC, exceeding the original 440VAC specification. Capacitance and tolerance remain identical at 330 pF ±10%. The temperature coefficient differs (Y5S versus B), but both are acceptable for safety-rated applications. The operating temperature range extends to -40°C ~ 125°C, providing broader environmental coverage than the original part. Physical dimensions are slightly larger (0.315" diameter, 0.472" height), but lead spacing remains compatible at 0.394" (10.00mm). This part is in active production with 1850 units in stock and carries ROHS3 compliance. This option is suitable for applications where higher voltage margin or extended temperature range provides design benefits.

Frequently Asked Questions (FAQ)

Q: Can CD45-B2GA331K-VKA be used as a direct replacement for CD75-B2GA331KYVKA?

A: Yes. Both parts share identical electrical specifications: 330 pF capacitance, ±10% tolerance, 440VAC rating, B temperature coefficient, and X1/Y1 safety ratings. Lead spacing is identical at 0.394" (10.00mm), ensuring PCB footprint compatibility. The primary difference is product status (active versus obsolete) and packaging format.

Q: What is the difference between the two substitute parts?

A: CD45-B2GA331K-VKA maintains the exact electrical specifications of the original part. VY1331K31Y5SQ6UV0 offers higher voltage rating (760VAC versus 440VAC) and extended low-temperature operation (-40°C versus -25°C). Both maintain 330 pF capacitance, ±10% tolerance, and X1/Y1 safety ratings. Physical dimensions differ slightly between the two substitutes.

Q: Are there any temperature range limitations when substituting?

A: CD45-B2GA331K-VKA operates to 85°C maximum, compared to the original specification of 125°C. Applications requiring operation above 85°C should use VY1331K31Y5SQ6UV0, which operates to 125°C. For applications operating below 85°C, both substitutes are acceptable.

Q: Do the physical dimension differences affect PCB layout?

A: Lead spacing remains constant at 0.394" (10.00mm) for all parts, ensuring direct footprint compatibility. Radial disc diameter and height vary slightly (CD45: 0.276" diameter, 0.433" height; VY1331: 0.315" diameter, 0.472" height). These dimensional differences do not affect electrical performance or mounting compatibility but may require clearance verification in space-constrained layouts.

Q: Are all substitute parts RoHS compliant?

A: Yes. All parts listed carry ROHS3 compliance certification, meeting current environmental and hazardous substance restrictions.

Q: What is the difference in packaging between the original and substitute parts?

A: The original CD75-B2GA331KYVKA is supplied in standard packaging format. Both substitutes are supplied in Cut Tape (CT) format, which is standard for active production components and compatible with automated assembly processes.
