Substitute Part Grouping Explanation

Substitution eligibility for the CD42FD333FO3F is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 0.033 µF (exact match required)
• Tolerance: ±1% (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 configuration: Radial (exact match required)
• Lead spacing: 1.063" / 27.00 mm (exact match required)
• Physical dimensions: 1.441" L × 0.358" W / 36.60 mm × 9.10 mm (exact match required)

Environmental Parameters:

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

The CD42FD333FO3 qualifies as a parametric equivalent based on identical electrical, mechanical, and environmental specifications. Differences in compliance status and inventory levels do not affect functional interchangeability in circuit applications.

Engineering Selection Recommendations

Primary Selection: CD42FD333FO3F

The CD42FD333FO3F is the recommended primary choice for new designs and applications requiring compliance with current environmental regulations. This part carries ROHS3 compliance certification and REACH Unaffected status, meeting modern procurement standards for electronics manufacturing. With 954 units in current inventory, supply availability is established.

Alternative Selection: CD42FD333FO3

The CD42FD333FO3 is functionally equivalent across all electrical and mechanical parameters and is suitable for applications where legacy compliance status is acceptable or where regulatory requirements do not mandate ROHS3 or REACH compliance. This part carries RoHS Non-Compliant and REACH Affected designations. Selection of this substitute should be based on specific project compliance requirements and regulatory jurisdiction. Current inventory of 820 units supports availability for qualified applications.

Compliance Considerations

Selection between these parts must account for end-use application requirements and regional regulatory frameworks. Applications subject to EU directives, RoHS regulations, or REACH requirements should specify the CD42FD333FO3F. Applications in jurisdictions without such mandates or legacy systems may utilize the CD42FD333FO3.

Frequently Asked Questions (FAQ)

Q: Are CD42FD333FO3F and CD42FD333FO3 electrically interchangeable?

A: Yes. Both parts are identical in capacitance (0.033 µF), tolerance (±1%), voltage rating (500 V), and dielectric material (mica). They perform identically in circuit applications.

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

A: Yes. Both parts share identical mechanical specifications: radial through-hole mounting, 1.063" (27.00 mm) lead spacing, and physical dimensions of 1.441" L × 0.358" W (36.60 mm × 9.10 mm). PCB footprints and assembly processes are compatible.

Q: What is the difference between these two parts?

A: The primary differences are compliance certifications. CD42FD333FO3F is ROHS3 Compliant and REACH Unaffected. CD42FD333FO3 is RoHS Non-Compliant and REACH Affected. Electrical and mechanical performance are identical.

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

A: Specify CD42FD333FO3F for new designs unless specific project constraints require the alternative. This part meets current environmental compliance standards.

Q: Are there any temperature or voltage derating considerations between these parts?

A: No. Both parts operate across the identical temperature range (-55°C to 125°C) and are rated for 500 V. No derating differences exist.

Q: Can I substitute CD42FD333FO3 for CD42FD333FO3F in existing designs?

A: Substitution is possible only if project compliance requirements permit use of RoHS Non-Compliant and REACH Affected components. Verify compliance obligations before substitution.

Q: What is the lead spacing for these radial capacitors?

A: Lead spacing is 1.063 inches (27.00 mm) for both parts, measured center-to-center between the two radial leads.

Q: Are these parts suitable for high-frequency applications?

A: Mica dielectric capacitors are suitable for applications requiring stable capacitance across frequency ranges. Specific frequency response characteristics are not provided in the available parameters.
