CD5FY331JO3F Equivalent & Substitute Parts

Part Overview

The CD5FY331JO3F is a 330 pF mica capacitor manufactured by Cornell Dubilier Electronics (CDE) in the CD5 series. This through-hole radial capacitor operates at 50 V rated voltage with ±5% tolerance and is designed for general-purpose applications. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Finding equivalent substitute parts may be necessary due to inventory availability, supply chain considerations, or specific compliance requirements for end-use applications.

Engineering Selection Recommendations

CD5FY331JO3F (Primary Selection): The CD5FY331JO3F is the recommended primary selection for new designs and applications requiring ROHS3 compliance. This part carries REACH Unaffected status, making it suitable for applications with strict environmental and regulatory requirements. Current inventory of 1037 units supports immediate availability for production requirements.

CD5FY331JO3 (Conditional Substitute): The CD5FY331JO3 is electrically and mechanically equivalent to the main part number and shares identical electrical performance characteristics. However, this substitute part is RoHS non-compliant and carries REACH Affected status. Selection of this substitute is limited to applications where RoHS3 compliance is not mandated and REACH compliance is not a requirement. The substitute maintains full electrical and mechanical compatibility with the main part, including identical lead spacing, physical dimensions, and operating temperature range. Current inventory of 934 units is available.

Frequently Asked Questions (FAQ)

Q: Can CD5FY331JO3 be used as a direct replacement for CD5FY331JO3F?

A: The CD5FY331JO3 is electrically and mechanically equivalent to the CD5FY331JO3F. Both parts share identical capacitance (330 pF), tolerance (±5%), voltage rating (50 V), dielectric material (Mica), mounting type (Through Hole), package configuration (Radial), lead spacing (0.118" / 3.00mm), and physical dimensions. Direct substitution is possible from an electrical and mechanical standpoint. However, compliance differences must be evaluated: the CD5FY331JO3F is ROHS3 compliant and REACH Unaffected, while the CD5FY331JO3 is RoHS non-compliant and REACH Affected.

Q: What are the key differences between these two part numbers?

A: The primary differences are regulatory compliance and REACH status. The CD5FY331JO3F carries ROHS3 compliance and REACH Unaffected designation, while the CD5FY331JO3 is RoHS non-compliant and REACH Affected. All electrical parameters, mechanical specifications, and physical dimensions are identical between the two parts.

Q: Are the physical dimensions and lead spacing identical?

A: Yes. Both the CD5FY331JO3F and CD5FY331JO3 share identical physical dimensions of 0.272" L x 0.181" W (6.90mm x 4.60mm), maximum seated height of 0.240" (6.10mm), and lead spacing of 0.118" (3.00mm). These parts are mechanically interchangeable in through-hole PCB applications.

Q: What is the operating temperature range for these capacitors?

A: Both parts operate across the temperature range of -55°C to 125°C, providing consistent performance across industrial and commercial temperature environments.

Q: Which part should be selected for RoHS-compliant applications?

A: The CD5FY331JO3F must be selected for applications requiring RoHS3 compliance. The CD5FY331JO3 does not meet RoHS compliance requirements.
