CS17-F2GA103MYGS Equivalent & Substitute Parts

Part Overview

The CS17-F2GA103MYGS is a 10000 pF ceramic capacitor rated for 250VAC, manufactured by TDK Corporation. This radial, disc-type component is designed for safety-critical applications with X1, Y2 ratings. The part is currently obsolete, necessitating identification of functionally equivalent alternatives that maintain the same electrical and mechanical specifications for direct replacement in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CS17-F2GA103MYGS is determined by the following critical parameters:

Electrical Compatibility:

• Capacitance value must be 10000 pF
• Tolerance must be ±20%
• Voltage rating must be equal to or greater than 250VAC
• Temperature coefficient must be F
• Safety ratings must include X1, Y2 classification

Mechanical Compatibility:

• Mounting type must be Through Hole
• Package type must be Radial, Disc
• Lead configuration must accommodate standard PCB hole spacing

The substitute part DE2F3KY103MN3AU02F from Murata Electronics meets these criteria with a higher voltage rating (300VAC) and improved operating temperature range (-40°C ~ 125°C), making it a direct functional replacement.

Engineering Selection Recommendations

The DE2F3KY103MN3AU02F from Murata Electronics is the qualified substitute for the obsolete CS17-F2GA103MYGS. Selection is based on:

Electrical Equivalence: Both parts maintain identical capacitance (10000 pF), tolerance (±20%), temperature coefficient (F), and safety ratings (X1, Y2). The Murata part provides superior voltage margin at 300VAC versus the original 250VAC specification.

Compliance Status: The Murata substitute carries ROHS3 compliance certification, meeting current regulatory requirements. Both parts are REACH Unaffected and classified under ECCN EAR99 and HTSUS 8532.24.0060.

Mechanical Considerations: The substitute features a smaller physical footprint (0.551" diameter versus 0.650") and reduced height (0.669" versus 0.807"), with straight leads replacing the kinked lead style. Lead spacing is reduced from 0.394" to 0.295". These dimensional differences require PCB layout verification before implementation.

Availability: The Murata part is currently available with Last Time Buy status, whereas the original TDK part is obsolete.

Frequently Asked Questions (FAQ)

Q: Can the DE2F3KY103MN3AU02F directly replace the CS17-F2GA103MYGS without PCB modification?

A: Electrical substitution is valid. However, mechanical differences exist: the Murata part is smaller with different lead spacing (0.295" versus 0.394") and straight leads instead of kinked leads. PCB hole pattern compatibility must be verified before installation.

Q: Why is the substitute rated for 300VAC when the original is 250VAC?

A: Higher voltage rating provides design margin and does not affect circuit operation. A 300VAC-rated capacitor functions correctly in a 250VAC application.

Q: Are the safety ratings identical between both parts?

A: Yes. Both parts carry X1, Y2 safety classifications, maintaining compliance for safety-critical applications.

Q: What is the impact of the different operating temperature ranges?

A: The Murata substitute operates from -40°C to 125°C versus the original -25°C to 105°C. This extended range provides greater thermal margin but does not affect performance in applications within the original temperature specification.

Q: Does the smaller physical size of the substitute affect circuit performance?

A: Physical size does not affect electrical performance. The capacitance, tolerance, voltage rating, and temperature coefficient remain identical. PCB layout must accommodate the reduced footprint.
