CS45SL2GA100JANKA Equivalent & Substitute Parts

Part Overview

The CS45SL2GA100JANKA is a 10 pF ceramic capacitor manufactured by TDK Corporation, rated for 300VAC/440VAC operation with SL temperature coefficient. This high-voltage safety-rated component is designed for through-hole mounting in applications requiring reliable capacitive filtering and coupling in automotive and safety-critical circuits. The part maintains Active product status with full RoHS3 compliance and AEC-Q200 automotive qualification.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified parameter range for this product category.

Substitute Part Grouping Explanation

Substitution eligibility for the CS45SL2GA100JANKA is determined by strict equivalence across the following critical parameters:

Capacitance Value: 10 pF (exact match required)
Tolerance: ±5% (exact match required)
Voltage Rating: 300VAC/440VAC minimum (equal or higher acceptable)
Temperature Coefficient: SL (exact match required)
Mounting Configuration: Through Hole, Radial, Disc (exact match required)
Lead Spacing: 0.295" (7.50mm) (exact match required)
Regulatory Compliance: RoHS3 Compliant (minimum requirement)

The CS45SL2GA100JYNKA qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Differences in operating temperature range and specific safety certifications do not preclude substitution when application requirements fall within the substitute part's specified envelope.

Engineering Selection Recommendations

Both the CS45SL2GA100JANKA and CS45SL2GA100JYNKA maintain Active product status with full RoHS3 compliance and identical electrical specifications. Selection between these parts should be based on application-specific operating temperature requirements:

CS45SL2GA100JANKA: Select when application requires operation at temperatures below -40°C. This part carries AEC-Q200 automotive qualification and X1, Y2 safety ratings, providing comprehensive compliance for automotive and safety-critical applications.
CS45SL2GA100JYNKA: Select for applications operating within -40°C to 125°C range. This part carries X1, Y2 safety ratings and is suitable for safety applications within its specified temperature envelope.

Both parts are electrically and mechanically interchangeable within their respective operating temperature ranges. PCB footprint compatibility is identical, requiring no layout modifications for substitution.

Frequently Asked Questions (FAQ)

Q: Can CS45SL2GA100JYNKA replace CS45SL2GA100JANKA in all applications?

A: Substitution is valid when the application's minimum operating temperature does not fall below -40°C. The CS45SL2GA100JYNKA has a narrower low-temperature specification (-40°C minimum versus -55°C minimum for the main part). If your circuit operates at or above -40°C, the substitute part is fully compatible.

Q: Are there any PCB layout changes required when switching between these parts?

A: No. Both parts share identical mechanical specifications: 0.276" diameter, 0.295" lead spacing, through-hole radial disc configuration, and formed kinked leads. No footprint or layout modifications are necessary.

Q: Do both parts meet automotive safety requirements?

A: Both parts carry X1, Y2 safety ratings and RoHS3 compliance. The main part (CS45SL2GA100JANKA) additionally carries AEC-Q200 automotive qualification. For applications requiring AEC-Q200 certification, the main part is the specified choice.

Q: What is the significance of the SL temperature coefficient?

A: SL temperature coefficient indicates the capacitance stability characteristic across the operating temperature range. Both parts share this specification, ensuring equivalent frequency response and filtering performance across temperature variations.

Q: Are inventory considerations a factor in substitution decisions?

A: Inventory levels may influence procurement decisions but do not affect technical substitution eligibility. Both parts are manufactured by TDK Corporation and maintain Active product status with current stock availability.
