CM05CD050DO3 Mica Capacitor 5 pF 500V Equivalent & Substitute Parts

Part Overview

The CM05CD050DO3 is a 5 pF mica capacitor rated for 500 V with radial through-hole mounting, manufactured by Cornell Dubilier Electronics (CDE). This component is classified as Active product status and is designed for general-purpose applications requiring high voltage and stable capacitance characteristics. Mica capacitors in this specification are utilized in RF circuits, high-frequency applications, and precision timing networks where temperature stability and low dielectric loss are critical.

Substitute parts become necessary when the primary part number experiences supply constraints, inventory depletion, or when alternative compliance certifications are required for specific manufacturing or regulatory environments.

Substitute Part Grouping Explanation

Substitution eligibility for the CM05CD050DO3 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 5 pF
• Tolerance: ±0.5 pF
• Voltage Rating: 500 V
• Dielectric Material: Mica
• Operating Temperature Range: -55°C to 125°C
• Mounting Type: Through Hole
• Package Type: Radial
• Lead Spacing: 0.232" (5.90 mm)
• Physical Dimensions: 0.449" L × 0.169" W (11.40 mm × 4.30 mm)
• Height (Seated Max): 0.358" (9.10 mm)

The substitute parts CD15CD050DO3 and CD15CD050DO3F meet all mandatory electrical and mechanical parameters. Both are manufactured by Cornell Dubilier Electronics and belong to the CD15 series. Differences exist only in compliance certifications and moisture sensitivity classifications, which do not affect functional interchangeability in the specified application envelope.

Engineering Selection Recommendations

CM05CD050DO3 Primary Selection: Use the CM05CD050DO3 when inventory availability is confirmed and RoHS non-compliance is acceptable for the application environment. This part number represents the original specification baseline.

CD15CD050DO3 Substitute Selection: The CD15CD050DO3 provides functional equivalence with identical electrical and mechanical parameters. This part is suitable when CM05CD050DO3 inventory is unavailable. Both parts share RoHS non-compliant and REACH Affected status, making them interchangeable from a regulatory standpoint for applications where these certifications are not mandated.

CD15CD050DO3F Substitute Selection: The CD15CD050DO3F is the preferred substitute when RoHS3 compliance and REACH Unaffected status are required by design specifications, manufacturing standards, or end-market regulations. This part number maintains full electrical and mechanical equivalence while providing enhanced compliance certifications. Selection of CD15CD050DO3F eliminates regulatory documentation requirements associated with RoHS non-compliance and REACH Affected status.

All three part numbers are manufactured by Cornell Dubilier Electronics, share identical electrical performance characteristics, and are mechanically interchangeable in through-hole PCB applications with 0.232" (5.90 mm) lead spacing.

Frequently Asked Questions (FAQ)

Q: Can CM05CD050DO3 be directly replaced with CD15CD050DO3 or CD15CD050DO3F?

A: Yes. All three part numbers are direct functional equivalents. They share identical capacitance (5 pF), tolerance (±0.5 pF), voltage rating (500 V), dielectric material (mica), operating temperature range (-55°C to 125°C), mounting type (through hole), package type (radial), lead spacing (0.232" / 5.90 mm), and physical dimensions. Substitution is electrically and mechanically valid.

Q: What is the difference between CD15CD050DO3 and CD15CD050DO3F?

A: The primary differences are compliance certifications. CD15CD050DO3 is RoHS non-compliant and REACH Affected. CD15CD050DO3F is RoHS3 Compliant and REACH Unaffected. Both parts are electrically and mechanically identical. Selection depends on regulatory requirements of the application or manufacturing environment.

Q: Are there any physical differences between these part numbers?

A: No. All three parts have identical physical dimensions: 0.449" L × 0.169" W (11.40 mm × 4.30 mm), maximum seated height of 0.358" (9.10 mm), and lead spacing of 0.232" (5.90 mm). They are mechanically interchangeable in PCB layouts designed for radial through-hole capacitors.

Q: Which substitute should be selected for new designs?

A: For new designs, CD15CD050DO3F is the recommended selection. It provides RoHS3 compliance and REACH Unaffected status, eliminating potential regulatory constraints in future manufacturing or market transitions. Electrical performance is identical to CM05CD050DO3 and CD15CD050DO3.

Q: Can these parts be used interchangeably in high-frequency RF applications?

A: Yes. All three part numbers are mica capacitors with identical dielectric material, capacitance value, tolerance, and temperature stability characteristics. They are suitable for RF circuits, high-frequency applications, and precision timing networks where the specified electrical parameters are required.

Q: What is the lead spacing tolerance for PCB layout?

A: The lead spacing is 0.232" (5.90 mm) for all three part numbers. PCB footprints designed for this spacing accommodate all three parts without modification.

Q: Are moisture sensitivity considerations different between these parts?

A: CM05CD050DO3 has Moisture Sensitivity Level (MSL) 1 (Unlimited). CD15CD050DO3 and CD15CD050DO3F have MSL classified as Not Applicable. This indicates mica capacitors in this specification are not moisture-sensitive components and do not require special moisture control during storage or handling.
