CD15FD181GO3 Equivalent & Substitute Parts

Part Overview

The CD15FD181GO3 is a 180 pF mica capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 500 V operation in radial through-hole configuration. This component is classified as Active product status and is designed for general-purpose applications requiring stable capacitance and high voltage performance. Mica dielectric capacitors are selected when applications demand low loss, excellent frequency stability, and reliable performance across extended temperature ranges from -55°C to 125°C.

Substitute parts become necessary when primary inventory is depleted, when alternative series offer improved lead times, or when design flexibility permits selection from equivalent product lines within the same manufacturer's portfolio. The CD15FD181GO3 has documented equivalent alternatives that maintain identical electrical specifications and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the CD15FD181GO3 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part CM05FD181GO3 qualifies as a parametric equivalent based on the following criteria:

Electrical Parameter Equivalence:

• Capacitance value: 180 pF (identical)
• Voltage rating: 500 V (identical)
• Tolerance: ±2% (identical)
• Dielectric material: Mica (identical)
• Operating temperature range: -55°C to 125°C (identical)

Mechanical Parameter Equivalence:

• Mounting type: Through Hole (identical)
• Package configuration: Radial (identical)
• Lead spacing: 0.232" / 5.90 mm (identical)
• Physical dimensions: 0.461" L × 0.189" W (identical)
• Seated height: 0.370" / 9.40 mm (identical)

Series Differentiation: The CD15FD181GO3 belongs to the CD15 series, while CM05FD181GO3 belongs to the CM05 series. Both series are manufactured by Cornell Dubilier Electronics and share identical performance specifications for this capacitance value and voltage rating. The series designation reflects internal product line organization but does not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both CD15FD181GO3 and CM05FD181GO3 are Active status products manufactured by Cornell Dubilier Electronics and maintain full electrical and mechanical equivalence for 180 pF, 500 V mica capacitor applications.

Compliance Considerations: Both parts share identical RoHS non-compliance status and REACH Affected designation. Both are classified under ECCN EAR99 and HTSUS code 8532.29.0020. Selection between these parts does not introduce compliance differences.

Moisture Sensitivity: The CM05FD181GO3 specifies Moisture Sensitivity Level 1 (Unlimited), while the CD15FD181GO3 lists MSL as Not Applicable. This difference reflects documentation practices rather than functional performance variance. Mica dielectric capacitors inherently exhibit minimal moisture absorption, and both parts are suitable for standard storage and handling conditions without special moisture control requirements.

Inventory and Availability: CD15FD181GO3 inventory: 729 pieces. CM05FD181GO3 inventory: 1041 pieces. Selection may be influenced by required delivery quantities and lead time considerations.

Direct Substitution: The CM05FD181GO3 functions as a direct substitute for CD15FD181GO3 in all circuit applications. No circuit modifications, PCB redesign, or performance verification testing is required. Both parts are interchangeable at the component level.

Frequently Asked Questions (FAQ)

Q: Can CM05FD181GO3 replace CD15FD181GO3 in existing designs without PCB modification?

A: Yes. Both parts share identical lead spacing (0.232" / 5.90 mm), physical dimensions (0.461" L × 0.189" W), and seated height (0.370"). No PCB footprint changes are necessary. Direct substitution is possible.

Q: Are the electrical specifications identical between these two parts?

A: Yes. Capacitance (180 pF), voltage rating (500 V), tolerance (±2%), dielectric material (Mica), and operating temperature range (-55°C to 125°C) are identical. Circuit performance is equivalent.

Q: What is the difference between CD15 and CM05 series designations?

A: CD15 and CM05 are internal product line designations within Cornell Dubilier Electronics' mica capacitor portfolio. For the 180 pF, 500 V specification, both series deliver identical performance. The series designation does not affect functional compatibility or electrical characteristics.

Q: Does the MSL difference between the two parts affect storage or handling?

A: No. Mica dielectric capacitors exhibit minimal moisture sensitivity. The MSL notation difference reflects documentation classification rather than actual moisture absorption behavior. Both parts follow standard component storage practices without special humidity control requirements.

Q: Are both parts currently in active production?

A: Yes. Both CD15FD181GO3 and CM05FD181GO3 are classified as Active product status, indicating ongoing manufacture and availability from Cornell Dubilier Electronics.

Q: Do compliance certifications differ between these parts?

A: No. Both parts share identical RoHS non-compliance status, REACH Affected designation, ECCN classification (EAR99), and HTSUS code (8532.29.0020). Regulatory and compliance profiles are equivalent.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection may be based on inventory availability, supplier lead times, or internal design documentation preferences. Both deliver identical performance and reliability.
