Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD19FD301JO3 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 300 pF
• Tolerance: ±5%
• Rated voltage: 500 V
• Dielectric material: Mica

Mechanical Parameters:

• Mounting type: Through Hole
• Package configuration: Radial
• Lead spacing: 0.343" (8.70 mm)
• Physical dimensions: 0.642" L x 0.189" W (16.30 mm x 4.80 mm)
• Maximum seated height: 0.500" (12.70 mm)

Environmental Parameters:

• Operating temperature range: -55°C to 125°C

Parts meeting all these specifications are classified as parametric equivalents and direct substitutes. Compliance certifications and regulatory status are secondary considerations that do not affect functional substitutability but influence procurement decisions based on end-use requirements.

Parameter Comparison

Engineering Selection Recommendations

CD19FD301JO3 is suitable for applications where RoHS non-compliance is acceptable and REACH-affected material sourcing is permissible. This part maintains active product status with established supply availability.

CD19FD301JO3F is the direct parametric equivalent with identical electrical and mechanical specifications. This variant is ROHS3 compliant and REACH unaffected, making it the appropriate selection for designs requiring compliance with RoHS3 directives and REACH regulations. Both parts are active products from the same manufacturer and series.

Selection between these two parts depends solely on regulatory and compliance requirements of the end application. No functional or performance differences exist between them.

Frequently Asked Questions (FAQ)

Q: Can CD19FD301JO3F replace CD19FD301JO3 in existing designs?

A: Yes. CD19FD301JO3F is a parametric equivalent with identical capacitance (300 pF), tolerance (±5%), voltage rating (500 V), dielectric material (mica), operating temperature range (-55°C to 125°C), and mechanical specifications including lead spacing, package configuration, and physical dimensions. Direct substitution is electrically and mechanically compatible.

Q: What is the difference between these two parts?

A: The parts are electrically and mechanically identical. The differences are in regulatory compliance: CD19FD301JO3F is ROHS3 compliant and REACH unaffected, while CD19FD301JO3 is RoHS non-compliant and REACH affected. Selection depends on application compliance requirements.

Q: Are the physical dimensions identical?

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

Q: Do both parts operate across the same temperature range?

A: Yes. Both CD19FD301JO3 and CD19FD301JO3F operate across the identical temperature range of -55°C to 125°C.

Q: Which part should be selected for new designs?

A: Selection is based on regulatory requirements. For applications requiring RoHS3 compliance or REACH compliance, CD19FD301JO3F is the appropriate choice. For applications without these requirements, either part is functionally equivalent.
