Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD16FD221JO3 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must satisfy the following requirements:

Electrical Parameters (Non-negotiable):

• Capacitance: 220 pF
• Tolerance: ±5%
• Voltage Rating: 500 V
• Dielectric Material: Mica
• Operating Temperature Range: -55°C to 125°C
• Features: RF, High Q, Low Loss

Mechanical Parameters (Non-negotiable):

• Mounting Type: Through Hole
• Package / Case: Radial
• Lead Spacing: 0.234" (5.94mm)
• Physical Dimensions: 0.429" L x 0.150" W (10.90mm x 3.80mm)
• Height - Seated (Max): 0.461" (11.70mm)

Regulatory & Compliance Parameters (Acceptable Variation):

• RoHS Status: May differ (RoHS non-compliant to RoHS3 compliant)
• REACH Status: May differ (REACH Affected to REACH Unaffected)

The CD16FD221JO3F qualifies as a parametric equivalent because it maintains identical electrical and mechanical specifications while offering improved regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution Criteria:

The CD16FD221JO3F is a direct parametric equivalent to the CD16FD221JO3. Both parts are manufactured by Cornell Dubilier Electronics in the CD16 series and maintain identical electrical and mechanical specifications across all critical parameters: 220 pF capacitance, ±5% tolerance, 500 V rating, mica dielectric, through-hole radial mounting, and RF/High Q/Low Loss characteristics.

Regulatory Compliance Advantage:

The CD16FD221JO3F offers improved regulatory compliance status. It is RoHS3 compliant (compared to RoHS non-compliant for the main part) and REACH Unaffected (compared to REACH Affected for the main part). These improvements make the substitute part suitable for applications subject to updated environmental and chemical restriction regulations.

Inventory Availability:

Both parts are active in production with adequate stock levels. The substitute part (CD16FD221JO3F) has higher inventory availability at 1448 units compared to 1110 units for the main part.

Selection Logic:

• Use CD16FD221JO3F when RoHS3 compliance or REACH compliance is required by design specifications or regulatory requirements.
• Use CD16FD221JO3 when legacy compliance status is acceptable and the part is already qualified in existing designs.
• Both parts are electrically and mechanically interchangeable with no circuit redesign required.
