Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD19FD102FO3 is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Capacitance value (1000 pF), tolerance (±1%), and rated voltage (500 V) must be identical
• Dielectric Type: Mica material is mandatory for functional equivalence
• Thermal Performance: Operating temperature range (-55°C to 125°C) must be maintained
• Mechanical Compatibility: Through-hole radial mounting, lead spacing (0.343" / 8.70 mm), and physical envelope dimensions must match exactly
• Series Classification: CD19 series designation ensures design compatibility

The substitute part CD19FD102FO3F meets all these criteria and is classified as a parametric equivalent. The primary distinction between the main part and its substitute relates to regulatory compliance certifications rather than functional or mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

CD19FD102FO3F is the direct parametric equivalent for CD19FD102FO3. Selection between these parts should be based on regulatory compliance requirements:

• CD19FD102FO3F is preferred for applications subject to ROHS3 compliance mandates or where REACH-unaffected component status is required by procurement specifications
• CD19FD102FO3 remains suitable for applications without RoHS3 or REACH compliance constraints
• Both parts are active products with adequate inventory availability
• Electrical performance, thermal characteristics, and mechanical fit are identical across both part numbers
• PCB layout and circuit design require no modification when substituting between these parts

Frequently Asked Questions (FAQ)

Q: Are CD19FD102FO3 and CD19FD102FO3F electrically interchangeable?

A: Yes. Both parts have identical capacitance (1000 pF), tolerance (±1%), voltage rating (500 V), and operating temperature range (-55°C to 125°C). Electrical performance is equivalent.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Both parts share identical mechanical specifications: through-hole radial mounting, lead spacing (0.343" / 8.70 mm), physical dimensions (0.650" L x 0.220" W), and maximum seated height (0.520"). No PCB redesign is required.

Q: What is the primary difference between these two part numbers?

A: The primary difference is regulatory compliance. CD19FD102FO3F is ROHS3 compliant and REACH unaffected, while CD19FD102FO3 is RoHS non-compliant and REACH affected. Functional and mechanical specifications are identical.

Q: Which part should be selected for new designs?

A: Selection depends on applicable regulatory requirements. For applications requiring ROHS3 compliance or REACH-unaffected status, CD19FD102FO3F is the appropriate choice. Both parts are active products with production support.

Q: Are there inventory differences between these parts?

A: Yes. CD19FD102FO3F has 1175 pieces in stock, while CD19FD102FO3 has 987 pieces in stock. Both quantities support typical procurement volumes.

Q: Do these parts require different handling or storage procedures?

A: No. Both parts are mica capacitors with identical moisture sensitivity classification (Not Applicable) and storage requirements.
