Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD19FD221JO3 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 220 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage rating: 500 V (exact match required)
• Dielectric material: Mica (exact match required)

Mechanical Parameters:

• Mounting type: Through Hole (exact match required)
• Package form: Radial (exact match required)
• Lead spacing: 0.343" / 8.70 mm (exact match required)
• Physical dimensions: 0.642" L × 0.189" W (16.30 mm × 4.80 mm) (exact match required)

Environmental Parameters:

• Operating temperature range: -55°C to 125°C (exact match required)

Substitute parts must satisfy all parameters listed above without deviation. The CD19FD221JO3F meets all substitution criteria and is classified as a parametric equivalent.

Engineering Selection Recommendations

CD19FD221JO3 (Main Part):

• Use when RoHS non-compliant designs are acceptable or required by specification
• Use when REACH-affected material sourcing is permissible
• Current inventory: 838 units available

CD19FD221JO3F (Substitute):

• Use for designs requiring ROHS3 compliance
• Use for applications where REACH-unaffected sourcing is mandated
• Use when higher inventory availability is advantageous (1072 units in stock)
• Provides identical electrical and mechanical performance to the main part

Both parts are active products from the same manufacturer and series. Selection between them is determined by regulatory compliance requirements and supply availability, not by electrical or mechanical performance differences.

Frequently Asked Questions (FAQ)

Q: Can CD19FD221JO3F be used as a direct replacement for CD19FD221JO3?

A: Yes. The CD19FD221JO3F is a parametric equivalent with identical capacitance (220 pF), tolerance (±5%), voltage rating (500 V), dielectric material (mica), mounting type (through hole), package form (radial), lead spacing (0.343" / 8.70 mm), physical dimensions, and operating temperature range (-55°C to 125°C). Direct substitution is electrically and mechanically compatible.

Q: What is the difference between these two parts?

A: The primary differences are regulatory compliance status and inventory levels. The CD19FD221JO3F is ROHS3 compliant and REACH unaffected, while the CD19FD221JO3 is RoHS non-compliant and REACH affected. All electrical and mechanical specifications are identical.

Q: Which part should I select for a new design?

A: Selection depends on your design's regulatory requirements. If ROHS3 compliance is required, use CD19FD221JO3F. If REACH compliance is required, use CD19FD221JO3F. If neither compliance requirement applies, either part is suitable based on availability and cost considerations.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical dimensions: 0.642" L × 0.189" W (16.30 mm × 4.80 mm), maximum seated height of 0.500" (12.70 mm), and lead spacing of 0.343" (8.70 mm). PCB footprints are interchangeable.

Q: Can these parts be used interchangeably in existing assemblies?

A: Yes, provided the assembly's regulatory compliance requirements are satisfied by the substitute part's compliance status. Electrical performance and physical form factor are identical, ensuring functional interchangeability.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -55°C to 125°C, providing identical thermal performance characteristics.
