Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the CD5CC020DO3 is determined by electrical and mechanical parameter alignment within the specified tolerances and performance envelope. The following critical parameters define acceptable substitutes:

• Capacitance Value: 2 pF (exact match required)
• Tolerance: ±0.5pF (defines operational accuracy)
• Rated Voltage: 300 V (minimum electrical rating)
• Dielectric Type: Mica (required for temperature stability and performance characteristics)
• Operating Temperature Range: -55°C to 125°C (environmental operating envelope)
• Mounting Configuration: Through-hole radial configuration (PCB assembly compatibility)
• Lead Spacing: 0.118" (3.00mm) (mechanical fit on standard PCB patterns)

Parts matching all these parameters within their specified ranges qualify as direct parametric equivalents and are suitable for direct substitution without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The CD5CC020DO3F serves as the primary parametric equivalent to the CD5CC020DO3, with identical electrical and mechanical specifications. The primary distinction between these parts is compliance status: the CD5CC020DO3F is RoHS3 compliant, whereas the CD5CC020DO3 is non-compliant. For new designs and applications subject to RoHS regulations, the CD5CC020DO3F is the appropriate selection. Both parts maintain equivalent performance characteristics across all specified electrical parameters, operating temperature range, and mechanical fit requirements. The CD5CC020DO3F is additionally REACH Unaffected, providing favorable environmental compliance status for modern manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can CD5CC020DO3 and CD5CC020DO3F be used interchangeably? A: Yes. Both parts are parametric equivalents with identical capacitance, tolerance, voltage rating, dielectric material, temperature range, mounting type, package configuration, and lead spacing. The substitution is electrically and mechanically transparent.

Q: What is the difference between CD5CC020DO3 and CD5CC020DO3F? A: The parts are electrically and mechanically identical. CD5CC020DO3F is RoHS3 compliant and REACH Unaffected, while CD5CC020DO3 is RoHS non-compliant and REACH Affected. These differences reflect manufacturing compliance standards rather than functional performance.

Q: Which part should be specified for new designs? A: CD5CC020DO3F is recommended for new designs due to RoHS3 compliance alignment with current regulatory requirements and manufacturing practices. Current inventory status indicates adequate availability for both parts.

Q: Are mechanical dimensions identical between substitute parts? A: Yes. Both parts share identical dimensions (0.272" L x 0.110" W, 6.90mm x 2.80mm), height (0.189" / 4.80mm maximum), and lead spacing (0.118" / 3.00mm). Direct PCB substitution is possible without layout modification.

Q: What tolerance should be verified during assembly? A: Both parts maintain ±0.5pF tolerance. This tolerance level applies equally to all parametric equivalents in this group and does not require adjustment of circuit design parameters.
