CS65-B2GA101KYNKA Equivalent & Substitute Parts

Part Overview

The CS65-B2GA101KYNKA is a 100 pF ceramic capacitor manufactured by TDK Corporation, rated for 300VAC/440VAC operation with B temperature coefficient. This component is classified as Active product status and is designed for safety-critical applications requiring high voltage performance. The part is ROHS3 compliant and suitable for through-hole mounting in radial disc configurations.

Equivalent and substitute parts are identified when component availability changes, supply chain constraints occur, or design flexibility permits voltage and temperature coefficient variations within acceptable electrical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CS65-B2GA101KYNKA is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 100 pF
• Tolerance: ±10%
• Mounting Type: Through Hole
• Package Type: Radial, Disc
• Safety Ratings: X1, Y2
• RoHS Compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Voltage Rating: Minimum 300VAC (440VAC acceptable as higher rating)
• Temperature Coefficient: B or Y5S (both suitable for safety applications)
• Operating Temperature Range: Minimum -25°C ~ 125°C
• Physical Dimensions: Lead spacing 0.295" (7.50mm) maintained; body diameter variations acceptable within mechanical constraints

Two substitute parts meet these criteria: CS45-B2GA101K-NKA (TDK Corporation, same manufacturer) and VY2101K29Y5SS63V7 (Vishay Beyschlag/Draloric/BC Components, alternative manufacturer).

Parameter Comparison

Engineering Selection Recommendations

CS45-B2GA101K-NKA (TDK Corporation): This substitute maintains identical electrical specifications to the main part with the exception of voltage rating (440VAC only, versus 300VAC/440VAC dual rating). Both components share B temperature coefficient, identical capacitance and tolerance values, and equivalent safety certifications. This part is suitable for applications where 440VAC operation is specified or where 300VAC operation is acceptable at the higher voltage rating. Product status is Active with ROHS3 compliance confirmed.

VY2101K29Y5SS63V7 (Vishay Beyschlag/Draloric/BC Components): This substitute provides equivalent electrical performance with Y5S temperature coefficient in place of B coefficient. The Y5S coefficient offers extended lower temperature operation (-40°C versus -25°C minimum). Voltage rating is 440VAC, matching the CS45 substitute. Lead spacing and safety ratings remain identical. This part is suitable for applications requiring broader temperature range coverage or where alternative manufacturer sourcing is preferred. Product status is Active with ROHS3 compliance confirmed.

Both substitutes maintain the critical safety ratings (X1, Y2) and through-hole radial disc package configuration required for direct board-level replacement.

Frequently Asked Questions (FAQ)

Q: Can CS45-B2GA101K-NKA replace CS65-B2GA101KYNKA in all applications?

A: CS45-B2GA101K-NKA is suitable for replacement when the application operates at 440VAC or lower. If the circuit specifically requires dual 300VAC/440VAC rating capability, verify that 440VAC-only operation meets design requirements. All other electrical parameters (capacitance, tolerance, temperature coefficient, safety ratings) are identical.

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

A: Both B and Y5S coefficients are acceptable for safety-rated applications. B coefficient is specified for the main part and CS45 substitute. Y5S coefficient on the VY2101K29Y5SS63V7 provides identical performance with extended lower temperature operation (-40°C minimum versus -25°C). Selection depends on circuit temperature requirements.

Q: Are physical dimension differences significant?

A: Lead spacing is identical across all three parts (0.295" / 7.50mm), ensuring direct PCB compatibility. Body diameter varies slightly (7.00mm main, 6.50mm CS45, 7.50mm Vishay). These variations are within standard mechanical tolerances for radial disc packages and do not affect electrical performance or board-level mounting.

Q: Can VY2101K29Y5SS63V7 be used in safety-critical applications?

A: Yes. VY2101K29Y5SS63V7 carries identical X1, Y2 safety ratings and ROHS3 compliance as the main part, qualifying it for safety-critical applications.

Q: What inventory considerations apply to these substitutes?

A: CS65-B2GA101KYNKA: 1010 pcs in stock. CS45-B2GA101K-NKA: 1734 pcs in stock. VY2101K29Y5SS63V7: 12762 pcs in stock. Inventory levels may influence supply chain decisions.
