CD15CD120DO3 Mica Capacitor Equivalent & Substitute Parts

Part Overview

The CD15CD120DO3 is a 12 pF mica capacitor rated for 500 V operation, manufactured by Cornell Dubilier Electronics (CDE). This radial through-hole component is designed for general-purpose applications requiring stable capacitance and high voltage performance across extended temperature ranges. The part maintains Active product status and is currently available in inventory.

Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when specific compliance requirements must be met, or when procurement optimization is required while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CD15CD120DO3 are identified based on strict parametric equivalence. The following electrical and mechanical parameters must remain identical for a part to qualify as a direct substitute:

• Capacitance value: 12 pF
• Tolerance specification: ±0.5 pF
• Voltage rating: 500 V minimum
• Dielectric type: Mica
• Mounting configuration: Through Hole Radial
• Lead spacing: 0.232" (5.90 mm)
• Physical dimensions: 0.449" L x 0.169" W (11.40 mm x 4.30 mm)
• Height seated maximum: 0.358" (9.10 mm)
• Operating temperature range: -55°C to 125°C

Substitution is permitted only when all parameters listed above are identical. Compliance certifications and RoHS status may differ between equivalent parts without affecting functional substitutability.

Engineering Selection Recommendations

The CD15CD120DO3F qualifies as a parametric equivalent substitute for the CD15CD120DO3. Both parts are manufactured by Cornell Dubilier Electronics within the CD15 series and maintain identical electrical and mechanical specifications.

Selection based on compliance requirements:

• CD15CD120DO3: Select when RoHS non-compliant components are acceptable and REACH-affected materials are permitted by design specifications.

• CD15CD120DO3F: Select when ROHS3 compliance is required or when REACH-unaffected status is mandated by procurement or regulatory requirements.

Both parts deliver identical performance in circuit applications. The choice between them depends solely on compliance certifications and regulatory constraints applicable to the end application.

Frequently Asked Questions (FAQ)

Q: Can CD15CD120DO3F replace CD15CD120DO3 in existing designs?

A: Yes. The CD15CD120DO3F is a parametric equivalent with identical capacitance (12 pF), tolerance (±0.5 pF), voltage rating (500 V), dielectric material (mica), mounting type (through-hole radial), lead spacing (0.232"), and operating temperature range (-55°C to 125°C). Direct substitution is electrically and mechanically compatible.

Q: What is the difference between these two part numbers?

A: The primary differences are compliance certifications. CD15CD120DO3F is ROHS3 compliant and REACH unaffected, while CD15CD120DO3 is RoHS non-compliant and REACH affected. All electrical and mechanical parameters are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts share identical dimensions: 0.449" L x 0.169" W (11.40 mm x 4.30 mm), with maximum seated height of 0.358" (9.10 mm), and lead spacing of 0.232" (5.90 mm). PCB footprints are interchangeable.

Q: Which part should I specify for new designs?

A: Selection depends on compliance requirements. For designs requiring ROHS3 compliance or REACH-unaffected status, specify CD15CD120DO3F. For applications without these constraints, either part is acceptable based on availability and procurement preference.

Q: Are both parts currently available?

A: Yes. CD15CD120DO3 has 1092 pieces in stock, and CD15CD120DO3F has 1031 pieces in stock, both listed as new original inventory.
