CS14-F2GA103MYGKA Equivalent & Substitute Parts

Part Overview

The CS14-F2GA103MYGKA is a high-voltage ceramic capacitor manufactured by TDK Corporation, rated at 10000 pF with dual voltage specifications of 300VAC/440VAC. This through-hole radial disc capacitor is designed for safety-critical applications requiring X1, Y2 ratings. The part is currently active in production with 1058 units in stock. Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or when design requirements allow for voltage-rated alternatives that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CS14-F2GA103MYGKA is determined by the following critical parameters:

Electrical Parameters: Capacitance value (10000 pF), tolerance (±20%), and temperature coefficient (F) must remain identical. Voltage rating must meet or exceed the application requirement; the CS14 series supports dual voltage (300VAC/440VAC), while substitute parts in the CS45 series are rated at 440VAC only, which satisfies applications requiring 440VAC operation.

Mechanical Parameters: Through-hole mounting type, radial disc package configuration, physical dimensions (0.571" diameter, 14.50mm), lead spacing (0.295", 7.50mm), and kinked formed lead style must match to ensure PCB compatibility without redesign.

Compliance Parameters: Safety ratings (X1, Y2) and RoHS3 compliance must be maintained for applications in regulated environments.

The two substitute parts listed—CS45-F2GA103M-NKA and CS45-F2GA103M-GKA—both belong to the CS45 series and meet all substitution criteria for 440VAC-rated applications.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain active production status with TDK Corporation and full ROHS3 compliance, ensuring regulatory alignment with the original CS14-F2GA103MYGKA. The CS45-F2GA103M-NKA offers higher inventory availability (32823 units) compared to the CS45-F2GA103M-GKA (3884 units), making it the preferred choice for applications where supply chain continuity is a priority. Both substitutes are rated at 440VAC, which is suitable for any application originally designed for the dual-voltage CS14 series when the 440VAC rating is sufficient. All electrical parameters, mechanical dimensions, and safety certifications remain consistent across the three parts, enabling direct substitution without circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can CS45-F2GA103M-NKA and CS45-F2GA103M-GKA be used interchangeably with CS14-F2GA103MYGKA?

A: Yes, for applications requiring 440VAC operation. Both substitute parts maintain identical capacitance (10000 pF), tolerance (±20%), temperature coefficient (F), physical dimensions, lead spacing, and safety ratings (X1, Y2). The primary difference is the voltage rating: the original part supports 300VAC/440VAC, while the substitutes are rated at 440VAC only. If your application operates at 440VAC, either substitute is electrically and mechanically compatible.

Q: What is the difference between CS45-F2GA103M-NKA and CS45-F2GA103M-GKA?

A: Both parts are electrically and mechanically identical. The difference lies in inventory availability and packaging designation. CS45-F2GA103M-NKA has significantly higher stock (32823 units), while CS45-F2GA103M-GKA has lower availability (3884 units). Both are manufactured by TDK Corporation and carry identical electrical specifications and compliance certifications.

Q: Will substituting these parts require PCB redesign?

A: No. All three parts share identical physical dimensions (0.571" diameter, 14.50mm), lead spacing (0.295", 7.50mm), lead style (formed leads - kinked), and through-hole mounting configuration. Direct PCB compatibility is maintained without layout modification.

Q: Are the substitute parts suitable for safety-critical applications?

A: Yes. Both CS45 series substitutes maintain X1, Y2 safety ratings and ROHS3 compliance, meeting the same regulatory requirements as the original CS14-F2GA103MYGKA for safety-critical applications.

Q: What voltage rating should I select?

A: If your circuit operates at 440VAC, either substitute part is appropriate. If your circuit requires operation below 440VAC (such as 300VAC), the original CS14-F2GA103MYGKA with its dual-voltage rating may be preferred, though the 440VAC-rated substitutes will function correctly at lower voltages with additional safety margin.
