CDV19FF821JO3 Equivalent & Substitute Parts

Part Overview

The CDV19FF821JO3 is an 820 pF mica capacitor rated for 1 kV operation in a radial through-hole configuration, 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 performance. Mica dielectric capacitors are selected when applications demand low loss, excellent frequency stability, and reliable operation across extended temperature ranges from -55°C to 125°C. Substitute parts become necessary when addressing specific compliance requirements, managing inventory constraints, or accommodating design revisions that require RoHS compliance or REACH status modifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDV19FF821JO3 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must remain identical between the main part and any substitute:

• Capacitance Value: 820 pF (no variation permitted)
• Tolerance: ±5% (must match exactly)
• Voltage Rating: 1 kV (minimum requirement)
• Dielectric Type: Mica (material-specific requirement)
• Mounting Configuration: Through Hole Radial (form factor requirement)
• Lead Spacing: 0.343" (8.70mm) (PCB compatibility requirement)
• Temperature Range: -55°C to 125°C (operational envelope requirement)
• Series Family: CDV19 (product line consistency)

The identified substitute CDV19FF821JO3F meets all these criteria. The primary distinction between the main part and its substitute relates to regulatory compliance status: RoHS compliance level and REACH classification. These differences do not affect electrical or mechanical compatibility but address specific regulatory and supply chain requirements.

Parameter Comparison

Engineering Selection Recommendations

Electrical and Mechanical Compatibility: The CDV19FF821JO3F provides complete electrical and mechanical equivalence to the CDV19FF821JO3. All critical parameters including capacitance, tolerance, voltage rating, dielectric material, mounting configuration, lead spacing, and operating temperature range are identical. PCB layout, circuit performance, and thermal characteristics remain unchanged with this substitution.

Regulatory Compliance Considerations: The primary distinction between these parts is regulatory status. The CDV19FF821JO3F achieves ROHS3 compliance, whereas the main part CDV19FF821JO3 is RoHS non-compliant. Additionally, CDV19FF821JO3F is REACH Unaffected, compared to the main part's REACH Affected status. These differences are significant for applications subject to European Union regulatory requirements or customer specifications mandating RoHS compliance.

Supply Chain and Inventory Management: Both parts maintain Active product status from Cornell Dubilier Electronics. Current inventory levels show 955 units of CDV19FF821JO3 and 868 units of CDV19FF821JO3F available. Selection between these parts should be based on regulatory requirements applicable to the end application and geographic distribution channels.

Selection Criteria: Choose CDV19FF821JO3F when designs require RoHS3 compliance or when REACH Unaffected status is specified. Choose CDV19FF821JO3 when regulatory compliance is not a constraint and existing inventory or cost considerations favor the non-compliant variant. Both parts are functionally interchangeable from an electrical and mechanical standpoint.
