• Tolerance: ±1% (exact match required)
• Voltage Rating: 500 V (exact match required)
• Dielectric Type: Mica (exact match required)
• Mounting Configuration: Through Hole Radial (exact match required)
• Lead Spacing: 1.063" / 27.00 mm (exact match required)
• Physical Dimensions: 1.441" L x 0.358" W / 36.60 mm x 9.10 mm (exact match required)
• Temperature Range: -55°C to 125°C (exact match required)

The CD42FD333FO3F is identified as a parametric equivalent substitute. Both parts share identical electrical and mechanical specifications within the CD42 series from Cornell Dubilier Electronics. The primary distinction between these parts relates to regulatory compliance status, not functional performance.

Parameter Comparison

Engineering Selection Recommendations

Functional Equivalence: The CD42FD333FO3 and CD42FD333FO3F are functionally equivalent across all electrical and mechanical parameters. Both parts deliver identical capacitance, voltage rating, tolerance, temperature performance, and physical form factor. Selection between these parts is not driven by performance requirements but by regulatory and compliance considerations.

Compliance Considerations: The CD42FD333FO3F carries ROHS3 compliance certification, whereas the CD42FD333FO3 is RoHS non-compliant. The CD42FD333FO3F is also REACH Unaffected, while the CD42FD333FO3 is REACH Affected. Applications subject to RoHS3 or REACH regulatory requirements should specify the CD42FD333FO3F variant.

Supply Chain Flexibility: Both parts maintain Active product status with adequate inventory levels. The CD42FD333FO3F currently shows higher stock availability (954 units versus 820 units), supporting procurement planning for high-volume applications.

Export and Trade Considerations: Both parts share identical ECCN (EAR99) and HTSUS (8532.29.0020) classifications, indicating equivalent export control and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can CD42FD333FO3F be used as a direct replacement for CD42FD333FO3?

A: Yes. The CD42FD333FO3F is a direct parametric equivalent. All electrical specifications (capacitance, tolerance, voltage, temperature range) and mechanical dimensions (lead spacing, physical size, mounting type) are identical. The parts are interchangeable from a functional and physical standpoint.

Q: What is the difference between CD42FD333FO3 and CD42FD333FO3F?

A: The primary differences are regulatory compliance status. The CD42FD333FO3F is ROHS3 Compliant and REACH Unaffected, while the CD42FD333FO3 is RoHS non-compliant and REACH Affected. No functional or performance differences exist between the two parts.

Q: Which part should I select for new designs?

A: For new designs subject to RoHS3 or REACH regulatory requirements, specify CD42FD333FO3F. For applications without such regulatory constraints, either part is acceptable based on availability and procurement lead time.

Q: Are the physical dimensions and lead spacing identical?

A: Yes. Both parts share identical dimensions (1.441" L x 0.358" W / 36.60 mm x 9.10 mm), lead spacing (1.063" / 27.00 mm), and maximum seated height (0.890" / 22.60 mm). PCB layout and mechanical assembly are identical for both parts.

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

A: Yes. Both CD42FD333FO3 and CD42FD333FO3F are rated for continuous operation across -55°C to 125°C. This temperature range supports industrial and harsh environment applications.

Q: What is the tolerance specification?

A: Both parts carry ±1% tolerance on the 0.033 µF capacitance value. This tight tolerance supports precision circuit applications requiring stable capacitance values.

Q: Are these parts suitable for 500 V applications?

A: Yes. Both parts are rated for 500 V continuous operation. The mica dielectric material provides stable performance at this voltage level across the full operating temperature range.
