Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD16FD182JO3 is determined by strict equivalence across the following parameters:

• Capacitance Value: 1800 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating: 500 V (exact match required)
• Dielectric Material: Mica (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Configuration: Radial (exact match required)
• Lead Spacing: 0.234" / 5.94 mm (exact match required)
• Physical Dimensions: 0.469" L x 0.252" W / 11.90 mm x 6.40 mm (exact match required)
• Height - Seated (Max): 0.520" / 13.20 mm (exact match required)

The CD16FD182JO3F qualifies as a parametric equivalent because all electrical and mechanical specifications are identical to the primary part. The distinction between these parts lies in regulatory compliance status and packaging designation.

Parameter Comparison

Engineering Selection Recommendations

CD16FD182JO3 is suitable for applications where RoHS non-compliance is acceptable and REACH-affected materials are permitted by design specifications. This part maintains full electrical and mechanical compatibility with all RF circuit designs specified for 1800 pF, 500 V mica capacitors in radial through-hole configuration.

CD16FD182JO3F is the appropriate selection for designs requiring RoHS3 compliance and REACH-unaffected material composition. This variant is functionally and mechanically identical to the CD16FD182JO3 and provides regulatory compliance for applications subject to environmental and hazardous substance restrictions. The CD16FD182JO3F also offers higher inventory availability (1590 units versus 806 units).

Both parts are Active in product status and suitable for new designs. Selection between these equivalents depends solely on regulatory compliance requirements applicable to the end application and geographic market.

Frequently Asked Questions (FAQ)

Q: Are CD16FD182JO3 and CD16FD182JO3F electrically interchangeable?

A: Yes. Both parts have identical electrical specifications: 1800 pF capacitance, ±5% tolerance, 500 V rating, and -55°C to 125°C operating temperature range. They are functionally equivalent in all RF circuit applications.

Q: Are these parts mechanically interchangeable?

A: Yes. Both parts share identical mechanical specifications including radial through-hole mounting, 0.234" lead spacing, 0.469" L x 0.252" W dimensions, and 0.520" maximum seated height. PCB layout and mechanical assembly are identical.

Q: What is the difference between CD16FD182JO3 and CD16FD182JO3F?

A: The primary differences are regulatory compliance status and material composition. CD16FD182JO3F is RoHS3 compliant and REACH unaffected, while CD16FD182JO3 is RoHS non-compliant and REACH affected. All electrical and mechanical parameters are identical.

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

A: Selection depends on regulatory requirements. If RoHS3 compliance is required, use CD16FD182JO3F. If RoHS compliance is not a design requirement, either part is acceptable. CD16FD182JO3F offers higher inventory availability.

Q: Can I use these parts in high-frequency RF applications?

A: Yes. Both parts are specified with RF, High Q, and Low Loss features, making them suitable for RF tuning networks, impedance matching circuits, and other high-frequency applications requiring low dielectric loss and stable capacitance.

Q: Are there any temperature derating considerations?

A: No. Both parts operate across the full -55°C to 125°C temperature range without derating. The 500 V rating is maintained across this entire operating temperature range.
