CD5CC070DO3 Mica Capacitor - Equivalent & Substitute Parts

Part Overview

The CD5CC070DO3 is a 7 pF mica capacitor rated for 300 V with radial leads, manufactured by Cornell Dubilier Electronics (CDE) as part of the CD5 series. This component is designed for general-purpose applications requiring high-frequency stability and low loss characteristics inherent to mica dielectric materials. The main part carries RoHS non-compliant status, making equivalent or substitute parts necessary for applications requiring RoHS3 compliance or REACH unaffected certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for mica capacitors is determined by electrical and mechanical parameter matching across five critical dimensions:

1. Capacitance & Tolerance: The substitute must maintain identical capacitance value (7 pF) and tolerance (±0.5 pF) for circuit performance equivalence.
2. Voltage Rating: The substitute must meet or exceed the rated voltage (300 V) to ensure adequate dielectric breakdown protection.
3. Dielectric Material: Mica dielectric is required to preserve high-frequency stability and low-loss characteristics.
4. Mounting Type & Package: Through-hole radial mounting with identical lead spacing (3.00 mm) ensures direct PCB compatibility without board redesign.
5. Physical Dimensions: Identical body dimensions and seating height prevent mechanical conflicts in populated boards.

The CD5CC070DO3F qualifies as a parametric equivalent substitute, matching all critical electrical and mechanical parameters while providing enhanced compliance status (RoHS3 compliant, REACH unaffected).

Parameter Comparison

Engineering Selection Recommendations

The CD5CC070DO3F is a direct functional equivalent to the CD5CC070DO3, with identical electrical performance and mechanical compatibility. The primary differentiation is compliance status: CD5CC070DO3F achieves RoHS3 compliance and REACH unaffected designation, whereas CD5CC070DO3 carries RoHS non-compliant and REACH affected status.

Selection between these two parts depends on regulatory and supply-chain requirements:

• CD5CC070DO3: Use when RoHS and REACH compliance is not a requirement and legacy part inventory is available.
• CD5CC070DO3F: Use for designs requiring RoHS3 compliance, REACH unaffected certification, or to ensure future supply-chain compatibility with evolving regulatory requirements.

Both parts maintain active product status from Cornell Dubilier Electronics and are fully interchangeable in circuit operation.

Frequently Asked Questions (FAQ)

Q: Can CD5CC070DO3F replace CD5CC070DO3 directly on the PCB? A: Yes. Both parts are identical in capacitance, voltage rating, dielectric material, and physical dimensions including lead spacing. Direct substitution requires no board redesign or component rework.

Q: Why does the CD5CC070DO3F have different compliance status? A: The "F" designation identifies parts manufactured to RoHS3 and REACH unaffected standards. Manufacturing process and materials in the CD5CC070DO3F variant ensure compliance with these environmental regulations, while the base CD5CC070DO3 does not.

Q: Are there any performance differences between these parts? A: No. Electrical performance is identical. Both provide 7 pF capacitance at ±0.5 pF tolerance, 300 V rating, and equivalent frequency stability across the -55°C to 125°C operating range.

Q: What determines if a mica capacitor is a valid substitute? A: Valid substitutes must match five core parameters: capacitance value and tolerance, voltage rating, dielectric material (mica), mounting configuration (through-hole radial), and physical dimensions including lead spacing. Deviation in any of these parameters requires circuit validation or board redesign.

Q: Is the CD5CC070DO3F more expensive due to RoHS compliance? A: Cost differences between compliant and non-compliant variants are not addressed in this technical specification. Consult with your procurement department or distributor for current pricing and inventory levels.
