CD19FD182FO3 Mica Capacitor - Equivalent & Substitute Parts

Part Overview

The CD19FD182FO3 is a 1800 pF mica capacitor rated for 500 V with ±1% tolerance, manufactured by Cornell Dubilier Electronics (CDE). This through-hole radial component is designed for general-purpose applications requiring stable capacitance and high voltage performance across the operating temperature range of -55°C to 125°C. The part is currently active in production with 863 units in stock.

Identification of substitute parts becomes necessary when the primary part reaches end-of-life status, inventory constraints occur, or when compliance requirements such as RoHS certification must be met for new designs or manufacturing revisions.

Substitute Part Grouping Explanation

Substitution of the CD19FD182FO3 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must match the following criteria:

• Capacitance Value: Exactly 1800 pF
• Tolerance: ±1% (no deviation permitted)
• Voltage Rating: 500 V minimum
• Dielectric Material: Mica (required for performance characteristics)
• Mounting Configuration: Through-hole radial with 0.343" (8.70 mm) lead spacing
• Physical Dimensions: 0.669" L × 0.240" W (17.00 mm × 6.10 mm), height seated maximum 0.532" (13.50 mm)
• Operating Temperature: -55°C to 125°C capability

The CD19FD182FO3F qualifies as a parametric equivalent because it maintains identical electrical specifications and mechanical dimensions while offering improved compliance status.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution Criteria Met: The CD19FD182FO3F is a direct parametric equivalent to the CD19FD182FO3. All electrical specifications, mechanical dimensions, and functional characteristics are identical.

Compliance Advantage: The substitute part CD19FD182FO3F provides RoHS3 compliance and REACH unaffected status, whereas the main part is RoHS non-compliant and REACH affected. For new designs or manufacturing revisions subject to environmental regulations, the CD19FD182FO3F is the appropriate selection.

Availability: The CD19FD182FO3F maintains higher inventory levels (1461 units versus 863 units), supporting supply chain continuity.

Application Compatibility: Both parts are suitable for identical circuit applications. No circuit redesign, PCB layout modification, or performance re-qualification is required when substituting the CD19FD182FO3F for the CD19FD182FO3.

Frequently Asked Questions (FAQ)

Q: Can the CD19FD182FO3F be used as a direct replacement for the CD19FD182FO3 without circuit modification?

A: Yes. The CD19FD182FO3F is a direct parametric equivalent with identical capacitance (1800 pF), tolerance (±1%), voltage rating (500 V), dielectric material (mica), mounting type (through-hole radial), lead spacing (0.343" / 8.70 mm), and physical dimensions. No circuit redesign is required.

Q: What is the difference between these two parts?

A: The primary differences are compliance certifications and inventory availability. The CD19FD182FO3F is RoHS3 compliant and REACH unaffected, while the CD19FD182FO3 is RoHS non-compliant and REACH affected. The substitute part also has higher stock availability (1461 units versus 863 units).

Q: Will the CD19FD182FO3F fit the same PCB footprint as the CD19FD182FO3?

A: Yes. Both parts have identical lead spacing of 0.343" (8.70 mm) and identical physical dimensions of 0.669" L × 0.240" W (17.00 mm × 6.10 mm). No PCB layout changes are necessary.

Q: Are there any performance differences between these capacitors?

A: No. Both parts operate across the same temperature range (-55°C to 125°C), maintain ±1% tolerance, and are rated for 500 V. Performance characteristics are identical.

Q: Which part should be selected for new designs?

A: The CD19FD182FO3F is recommended for new designs due to RoHS3 compliance and REACH unaffected status, ensuring alignment with current environmental regulations and supply chain requirements.
