CD15FD181GO3F Equivalent & Substitute Parts Reference

Part Overview

The CD15FD181GO3F 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 precision, temperature stability, and reliability across extended operating ranges are critical requirements. Substitute parts are identified when inventory constraints, compliance requirements, or series discontinuation necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the CD15FD181GO3F is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 180 pF
• Tolerance: ±2%
• Voltage Rating: 500 V
• Dielectric Material: Mica
• Operating Temperature Range: -55°C to 125°C
• Mounting Type: Through Hole
• Package Configuration: Radial
• Lead Spacing: 0.232" (5.90 mm)
• Physical Dimensions: 0.461" L × 0.189" W (11.70 mm × 4.80 mm)
• Height - Seated (Max): 0.370" (9.40 mm)

The substitute part CM05FD181GO3 meets all mandatory electrical and mechanical parameters, confirming parametric equivalence. Differences in series designation (CD15 versus CM05), RoHS compliance status, and REACH classification do not affect functional interchangeability in applications where these regulatory attributes are not contractually specified.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (CD15FD181GO3F): The CD15FD181GO3F is the preferred component for applications subject to ROHS3 compliance requirements and REACH-unaffected supply chain specifications. Active product status ensures continued availability and manufacturing support. This part is suitable for all general-purpose 180 pF, 500 V mica capacitor applications within the specified temperature range.

Substitute Selection (CM05FD181GO3): The CM05FD181GO3 provides electrical and mechanical equivalence and is suitable for applications where RoHS3 compliance and REACH status are not contractually mandated. This substitute is appropriate for legacy equipment, non-regulated applications, or situations where inventory availability of the primary part is constrained. Both parts maintain identical electrical performance, temperature stability, and physical form factor.

Compliance Considerations: Selection between these parts must account for end-product regulatory requirements. If ROHS3 compliance or REACH-unaffected status is specified in procurement documentation, the CD15FD181GO3F is the required choice. If no such specification exists, either part is electrically and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Can CM05FD181GO3 be used as a direct replacement for CD15FD181GO3F in PCB assembly?

A: Yes. Both parts are identical in capacitance (180 pF), voltage rating (500 V), tolerance (±2%), dielectric material (mica), operating temperature range (-55°C to 125°C), mounting type (through hole), package configuration (radial), lead spacing (0.232" / 5.90 mm), and physical dimensions (0.461" L × 0.189" W / 11.70 mm × 4.80 mm). PCB footprints and assembly processes require no modification.

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

A: The series designation indicates different product lines within Cornell Dubilier Electronics' mica capacitor portfolio. Both series share identical electrical specifications for this 180 pF, 500 V rating. The primary difference is regulatory compliance: CD15 is ROHS3 compliant and REACH unaffected, while CM05 is RoHS non-compliant and REACH affected.

Q: Which part should I specify for a new design?

A: Specify CD15FD181GO3F for new designs unless regulatory constraints or supply chain requirements dictate otherwise. Active product status and ROHS3 compliance provide assurance of long-term availability and regulatory alignment with current manufacturing standards.

Q: Are there any performance differences between these parts?

A: No. Both parts deliver identical electrical performance: 180 pF capacitance with ±2% tolerance, 500 V rated voltage, mica dielectric, and -55°C to 125°C operating temperature range. Mechanical dimensions, lead spacing, and mounting characteristics are identical.

Q: Can I mix CD15FD181GO3F and CM05FD181GO3 in the same assembly?

A: Yes, from an electrical and mechanical standpoint. However, if the end product is subject to ROHS3 or REACH compliance verification, mixing parts with different compliance statuses may create documentation and traceability complications. Consistent part selection within a single assembly is recommended for compliance documentation purposes.

Q: What inventory status should I consider?

A: CD15FD181GO3F has 1139 pcs in stock; CM05FD181GO3 has 1041 pcs in stock. Both are available as new original components in bulk packaging. Inventory levels should be verified at time of procurement, as stock quantities change based on demand and manufacturing schedules.
