Substitute Part Grouping Explanation

Substitute parts for the CD15ED820FO3 are identified based on strict parametric equivalence. The substitution logic requires that all electrical and mechanical parameters remain identical to the main part:

Critical Matching Parameters:

• Capacitance value: 82 pF (exact match required)
• Tolerance: ±1% (exact match required)
• Voltage rating: 500 V (exact match required)
• Dielectric material: Mica (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Radial (exact match required)
• Lead spacing: 0.232" / 5.90mm (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)

Substitutes may differ in compliance certifications (RoHS status, REACH classification) and inventory availability, but these differences do not affect electrical or mechanical compatibility. All substitute parts listed maintain identical functional performance and physical compatibility with the original design.

Engineering Selection Recommendations

CD15ED820FO3F as Direct Substitute:

The CD15ED820FO3F is a parametrically equivalent substitute for the CD15ED820FO3. Both parts are manufactured by Cornell Dubilier Electronics within the CD15 series and maintain identical electrical and mechanical specifications.

Compliance Considerations:

The primary distinction between these parts is regulatory compliance status. The CD15ED820FO3F achieves ROHS3 compliance and REACH Unaffected status, whereas the CD15ED820FO3 is RoHS non-compliant and REACH Affected. Selection between these parts should be based on the regulatory requirements of the end application and target market.

Application Suitability:

Both parts are suitable for general-purpose high-voltage applications requiring stable capacitance. The identical operating temperature range (-55°C to 125°C), voltage rating (500 V), and mica dielectric ensure equivalent performance in thermal and electrical stress conditions.

Inventory and Availability:

The CD15ED820FO3F currently maintains higher inventory availability (1055 pcs) compared to the CD15ED820FO3 (1004 pcs). This difference may influence supply chain decisions but does not affect technical compatibility.

Frequently Asked Questions (FAQ)

Q: Can CD15ED820FO3F be used as a direct replacement for CD15ED820FO3 in existing designs?

A: Yes. The CD15ED820FO3F is a direct parametric equivalent. All electrical specifications (capacitance, tolerance, voltage rating, temperature range) and mechanical dimensions (lead spacing, package type, physical size) are identical. No circuit redesign or PCB layout modification is required.

Q: What is the difference between RoHS non-compliant and ROHS3 Compliant status?

A: RoHS (Restriction of Hazardous Substances) compliance indicates adherence to EU directive 2011/65/EU (ROHS3). The CD15ED820FO3F meets ROHS3 requirements, while the CD15ED820FO3 does not. Selection depends on whether the end product must comply with RoHS regulations for sale in regulated markets.

Q: Does REACH Affected versus REACH Unaffected status affect electrical performance?

A: No. REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) status relates to chemical substance compliance and supply chain documentation, not electrical or mechanical performance. Both parts function identically in circuit applications.

Q: Are the physical dimensions and lead spacing identical between these parts?

A: Yes. Both parts have identical dimensions (0.449" L x 0.181" W / 11.40mm x 4.60mm), maximum seated height (0.358" / 9.10mm), and lead spacing (0.232" / 5.90mm). They are mechanically interchangeable on PCBs designed for radial through-hole components.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts maintain the same operating temperature range of -55°C to 125°C and use identical mica dielectric material, ensuring equivalent thermal stability and performance across the full temperature envelope.

Q: What is the significance of the ±1% tolerance specification?

A: The ±1% tolerance indicates that the actual capacitance value will be within 0.82 pF of the nominal 82 pF specification. This precision class is maintained by both the CD15ED820FO3 and CD15ED820FO3F, ensuring equivalent circuit performance.
