CS14-F2GA103MYVKA Equivalent & Substitute Parts

Part Overview

The CS14-F2GA103MYVKA is a 10000 pF ceramic capacitor rated for 300VAC/440VAC operation, manufactured by TDK Corporation. This high-voltage safety-rated component (X1, Y2) is designed for through-hole mounting in applications requiring reliable AC voltage suppression and filtering. The part is currently in active production status with 740 units in stock. Substitute parts become necessary when addressing supply constraints, packaging format requirements, or specific voltage rating needs within the allowable parameter range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CS14-F2GA103MYVKA is determined by the following critical parameters:

• Capacitance Value: Must be 10000 pF (no tolerance variation acceptable)
• Tolerance: Must be ±20%
• Temperature Coefficient: Must be F
• Safety Ratings: Must maintain X1, Y2 classification
• Mounting Type: Must be Through Hole
• Package Configuration: Must be Radial, Disc
• Lead Spacing: Must be 0.295" (7.50mm)
• Voltage Rating: Must be rated for minimum 300VAC operation

The two qualified substitutes meet these criteria while offering variations in voltage rating (440VAC maximum) and operating temperature range extensions, with differences in physical dimensions and lead style that remain compatible with standard through-hole PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

CS45-F2GA103M-VKA is the primary substitute option. It is manufactured by TDK Corporation (same OEM as the main part), maintains active production status, and provides identical electrical and mechanical specifications with the exception of voltage rating limited to 440VAC. This part is suitable for applications where the full 300VAC/440VAC dual-rating is not required. The CS45 series represents a direct functional equivalent with 3944 units currently available.

DE2F3KY103MN3AU02F is a secondary substitute manufactured by Murata Electronics. This part carries Last Time Buy status, indicating discontinued production. While it meets all critical electrical parameters and safety ratings, the extended operating temperature range (-40°C ~ 125°C) and slightly reduced physical diameter (14.00mm versus 14.50mm) should be evaluated for specific application requirements. This option is suitable only when supply from the primary substitute is unavailable and long-term availability is not a concern.

Frequently Asked Questions (FAQ)

Q: Can CS45-F2GA103M-VKA be used in place of CS14-F2GA103MYVKA?

A: Yes. Both parts share identical capacitance (10000 pF), tolerance (±20%), temperature coefficient (F), safety ratings (X1, Y2), operating temperature range (-25°C ~ 125°C), and mechanical specifications (lead spacing, mounting type, package configuration). The CS45 variant is rated for 440VAC maximum, which is compatible with applications requiring 300VAC or 440VAC operation.

Q: What is the difference between the two substitute parts?

A: CS45-F2GA103M-VKA is a TDK product in active production with 440VAC rating. DE2F3KY103MN3AU02F is a Murata product in Last Time Buy status with 300VAC rating and extended low-temperature capability (-40°C minimum). Both maintain identical capacitance, tolerance, and safety classifications.

Q: Are there physical dimension differences that affect PCB layout?

A: The main part and CS45 substitute share identical disc diameter (14.50mm) and lead spacing (7.50mm). The Murata substitute has a slightly smaller diameter (14.00mm) but maintains the same 7.50mm lead spacing, making it compatible with existing through-hole PCB designs without layout modification.

Q: Why is DE2F3KY103MN3AU02F marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued this product line. While currently available (777 units in stock), future procurement will not be possible. This part should be selected only when primary substitutes are unavailable and immediate application needs are critical.

Q: Do all three parts meet the same safety and compliance standards?

A: Yes. All three parts are ROHS3 compliant, carry X1, Y2 safety ratings, and are classified for safety applications. Compliance certifications are equivalent across all options.
