Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD70-B2GA151KYVKA is determined by the following critical parameters:

Primary Matching Criteria:

• Capacitance value: 150 pF
• Tolerance: ±10%
• Safety ratings: X1, Y1
• Mounting type: Through Hole
• Lead spacing: 0.394" (10.00mm)
• RoHS3 compliance

Voltage Rating Consideration: Substitute parts must maintain equal or higher voltage ratings. The main part operates at 440VAC; substitutes rated at 440VAC or above are acceptable.

Temperature Coefficient: Temperature coefficient variations (B vs. Y5S) are permissible when the substitute's operating temperature range encompasses or exceeds the application requirements.

Physical Dimensions: While package type (Radial, Disc) must remain consistent, minor variations in diameter and height are acceptable provided lead spacing remains at 0.394" (10.00mm) for PCB compatibility.

Parameter Comparison

Engineering Selection Recommendations

CD45-B2GA151K-VKA (TDK Corporation)

This substitute maintains identical electrical specifications to the main part: 150 pF capacitance, ±10% tolerance, 440VAC rating, and B temperature coefficient. Both components are TDK products with consistent manufacturing standards. The CD45 series is active production status, ensuring long-term availability. Physical dimensions are slightly reduced (6.50mm diameter vs. 7.00mm), which may provide layout advantages in space-constrained applications. Lead spacing remains at 0.394" (10.00mm), ensuring direct PCB compatibility. ROHS3 compliance is maintained. This substitute is the primary choice for direct replacement in existing designs.

VY1151K31Y5SQ6UV0 (Vishay Beyschlag/Draloric/BC Components)

This substitute provides enhanced voltage rating at 760VAC, exceeding the main part's 440VAC specification. Capacitance and tolerance remain identical at 150 pF ±10%. The Y5S temperature coefficient and extended operating range (-40°C ~ 125°C) offer broader environmental performance compared to the B coefficient and -25°C ~ 105°C range of the main part. Lead spacing is maintained at 0.394" (10.00mm) for PCB compatibility. Physical dimensions are slightly larger (8.00mm diameter, 12.00mm height). ROHS3 compliance is confirmed. This substitute is suitable for applications requiring higher voltage margin or extended temperature operation.

Frequently Asked Questions (FAQ)

Q: Can CD45-B2GA151K-VKA be used as a direct replacement for CD70-B2GA151KYVKA?

A: Yes. Both parts share identical electrical specifications: 150 pF, ±10% tolerance, 440VAC rating, B temperature coefficient, and X1, Y1 safety ratings. Lead spacing is identical at 0.394" (10.00mm). Physical dimensions differ slightly, but both maintain radial disc package type with through-hole mounting. The CD45 is active production status, addressing the obsolescence of the CD70.

Q: What are the differences between the two TDK substitutes?

A: The CD70 and CD45 are both TDK products with identical electrical ratings. The primary difference is product status: CD70 is obsolete while CD45 is active. Physical dimensions vary slightly: CD45 has a 6.50mm diameter versus CD70's 7.00mm diameter. Both maintain the same lead spacing and electrical performance.

Q: Is the Vishay VY1151K31Y5SQ6UV0 compatible with the original CD70-B2GA151KYVKA?

A: Yes, with considerations. The Vishay part maintains 150 pF capacitance, ±10% tolerance, X1, Y1 safety ratings, and 0.394" (10.00mm) lead spacing. The voltage rating is higher at 760VAC versus 440VAC, which is acceptable for direct substitution. Temperature coefficient differs (Y5S vs. B) and operating range is extended (-40°C ~ 125°C vs. -25°C ~ 105°C). Physical dimensions are slightly larger. This substitute is suitable when higher voltage margin or extended temperature performance is beneficial.

Q: Will the larger physical dimensions of the Vishay part affect PCB layout?

A: The Vishay VY1151K31Y5SQ6UV0 has a diameter of 8.00mm and height of 12.00mm compared to the CD70's 7.00mm diameter and 11.00mm height. Lead spacing remains at 0.394" (10.00mm), ensuring hole compatibility. PCB layout impact depends on available board space. Verify clearance around the component footprint before implementation.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The CD70-B2GA151KYVKA, CD45-B2GA151K-VKA, and VY1151K31Y5SQ6UV0 are all ROHS3 compliant, meeting environmental and regulatory requirements for current manufacturing standards.

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

A: Temperature coefficient B indicates a ceramic capacitor with specific capacitance change characteristics across temperature. Y5S is a different temperature coefficient classification with distinct performance parameters. The Vishay part with Y5S coefficient provides an extended operating temperature range (-40°C ~ 125°C) compared to the B coefficient range (-25°C ~ 105°C). Selection depends on application temperature requirements.
