CD10FC301JO3 Equivalent & Substitute Parts

Part Overview

The CD10FC301JO3 is a 300 pF mica capacitor rated for 300 V operation in a radial through-hole package, manufactured by Cornell Dubilier Electronics (CDE). This component is classified as Active product status and is designed for general-purpose applications requiring stable capacitance and high voltage tolerance. The CD10 series mica capacitor is widely used in RF circuits, timing networks, and high-reliability applications where temperature stability and low dielectric loss are critical.

Identifying equivalent and substitute parts becomes necessary when the original part number reaches end-of-life status, inventory constraints occur, or when design requirements mandate compliance with updated regulatory standards such as RoHS3 certification.

Engineering Selection Recommendations

CD10FC301JO3F as Primary Substitute:

The CD10FC301JO3F is a direct parametric equivalent to the CD10FC301JO3 across all electrical and mechanical specifications. Both components are manufactured by Cornell Dubilier Electronics within the CD10 series and maintain identical performance characteristics for capacitance, voltage rating, temperature range, and physical form factor.

Regulatory Compliance Consideration:

The CD10FC301JO3F provides enhanced regulatory compliance status compared to the main part. The substitute achieves ROHS3 compliance, whereas the original CD10FC301JO3 is RoHS non-compliant. Additionally, the CD10FC301JO3F is REACH Unaffected, compared to the main part's REACH Affected status. These compliance differences may be significant for applications subject to European Union regulatory requirements or customer-mandated environmental standards.

Inventory & Availability:

Current inventory levels show 1074 pieces of CD10FC301JO3F available compared to 645 pieces of CD10FC301JO3, indicating improved supply availability for the substitute part.

Application Compatibility:

Both parts are suitable for identical circuit applications. The radial through-hole package, lead spacing, and physical dimensions ensure direct board-level compatibility without PCB redesign. The ±5% tolerance and 300 V rating support equivalent performance in RF circuits, timing networks, and high-reliability applications.
