Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CS65-B2GA101KYGKA is determined by the following critical parameters:

Electrical Equivalence: Capacitance value (100 pF) and tolerance (±10%) must match exactly. Voltage rating must meet or exceed 300VAC minimum requirement; 440VAC rating is acceptable as a higher-rated substitute.

Safety Compliance: Both X1 and Y2 safety ratings must be present. These ratings are mandatory for applications requiring safety-grade capacitors.

Mechanical Compatibility: Through-hole mounting with radial, disc package and formed kinked leads ensures physical fit in existing PCB layouts. Lead spacing of 0.295" (7.50mm) is the standard for this package class.

Regulatory Compliance: ROHS3 compliance is required for all substitutes to maintain environmental and regulatory standards.

Temperature Performance: Temperature coefficient and operating temperature range may vary within acceptable limits for the application, provided the operating range encompasses the circuit's thermal requirements.

Parameter Comparison

Engineering Selection Recommendations

CS65-B2GA101KANKA (TDK Corporation): This substitute maintains identical electrical specifications to the main part while offering extended lower operating temperature range (-55°C vs. -25°C). It carries AEC-Q200 automotive qualification in addition to standard safety ratings, making it suitable for both general industrial and automotive safety applications. Product status is Active with ROHS3 compliance confirmed.

VY2101K29Y5SS63V7 (Vishay Beyschlag/Draloric/BC Components): This substitute meets all electrical requirements with 440VAC rating and maintains X1, Y2 safety certifications. The temperature coefficient differs (Y5S vs. B), and the operating temperature range is -40°C to 125°C. This part is suitable for applications where the Y5S temperature coefficient and specified operating range are acceptable. Product status is Active with ROHS3 compliance and REACH unaffected status confirmed.

Both substitutes are electrically and mechanically compatible with the original CS65-B2GA101KYGKA for direct replacement in safety-rated high-voltage applications.

Frequently Asked Questions (FAQ)

Q: Can CS65-B2GA101KANKA be used as a direct replacement for CS65-B2GA101KYGKA?

A: Yes. Both parts share identical capacitance (100 pF), tolerance (±10%), voltage rating (300VAC/440VAC), temperature coefficient (B), and safety ratings (X1, Y2). Physical dimensions and lead spacing are equivalent. The substitute offers extended temperature range and automotive qualification.

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

A: Temperature coefficient defines capacitance variation across temperature ranges. B coefficient is standard for general industrial applications. Y5S is specified for the Vishay substitute and operates within -40°C to 125°C. Selection depends on circuit thermal requirements.

Q: Are all three parts suitable for safety-rated applications?

A: Yes. All three parts carry X1 and Y2 safety ratings, meeting requirements for safety-grade capacitor applications. The CS65-B2GA101KANKA additionally carries AEC-Q200 automotive qualification.

Q: Do the substitutes fit the same PCB footprint?

A: Yes. All three parts feature identical lead spacing (0.295" / 7.50mm), radial disc package, and formed kinked leads. Physical mounting compatibility is confirmed for through-hole PCB layouts.

Q: What is the voltage rating difference between the main part and VY2101K29Y5SS63V7?

A: The main part is rated 300VAC/440VAC. The Vishay substitute is rated 440VAC only. The 440VAC rating of the substitute exceeds the 300VAC minimum requirement and is acceptable for direct replacement.

Q: Are all parts ROHS3 compliant?

A: Yes. All three parts are ROHS3 compliant. The Vishay substitute additionally confirms REACH unaffected status.
