CM05FD181FO3 Equivalent & Substitute Parts

Part Overview

The CM05FD181FO3 is a 180 pF mica capacitor rated for 500 V operation in a radial through-hole package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as Active product status and is suitable for general-purpose applications requiring high-voltage, precision capacitance in compact form factors.

Substitute parts are identified when electrical parameters (capacitance, voltage rating, tolerance, dielectric material, operating temperature range) and mechanical parameters (mounting type, package configuration, lead spacing, physical dimensions) align with the original specification. Equivalent alternatives enable procurement flexibility, inventory optimization, and continuity of supply.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CM05FD181FO3 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 180 pF (exact match required)
• Tolerance: ±1% (exact match required)
• Voltage rating: 500 V (exact match required)
• Dielectric material: Mica (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)

Mechanical Parameters:

• Mounting type: Through Hole (exact match required)
• Package configuration: Radial (exact match required)
• Lead spacing: 0.232" (5.90mm) (exact match required)
• Physical dimensions: 0.461" L x 0.189" W (11.70mm x 4.80mm) (exact match required)
• Maximum seated height: 0.370" (9.40mm) (exact match required)

All identified substitute parts meet these criteria and are manufactured by Cornell Dubilier Electronics (CDE) within the CM05 and CD15 series families.

Parameter Comparison

Engineering Selection Recommendations

CM05FD181FO3 (Original Part)

The CM05FD181FO3 maintains Active product status and is suitable for applications where RoHS non-compliance is acceptable. This part is REACH Affected and carries standard export classification under EAR99.

CD15FD181FO3 (Parametric Equivalent)

The CD15FD181FO3 is a direct parametric equivalent offering identical electrical and mechanical specifications. This part is also RoHS non-compliant and REACH Affected, matching the regulatory profile of the original CM05FD181FO3. Selection of this substitute is appropriate when supply of the CM05 series is constrained.

CD15FD181FO3F (Parametric Equivalent with Enhanced Compliance)

The CD15FD181FO3F is a parametric equivalent with ROHS3 compliance and REACH Unaffected status. This part is suitable for applications subject to RoHS3 directives or REACH restrictions. All electrical and mechanical parameters remain identical to the original specification. This variant provides regulatory flexibility for applications requiring enhanced environmental compliance.

Frequently Asked Questions (FAQ)

Q: Are the substitute parts electrically identical to the CM05FD181FO3?

A: Yes. The CD15FD181FO3 and CD15FD181FO3F are electrically identical to the CM05FD181FO3. All three parts share identical capacitance (180 pF), tolerance (±1%), voltage rating (500 V), dielectric material (Mica), and operating temperature range (-55°C ~ 125°C).

Q: Can the substitute parts be used in the same PCB layout as the original?

A: Yes. All substitute parts are mechanically identical to the CM05FD181FO3. Lead spacing (0.232" / 5.90mm), physical dimensions (0.461" L x 0.189" W / 11.70mm x 4.80mm), and maximum seated height (0.370" / 9.40mm) are identical across all three parts. Direct board-level substitution is supported without layout modification.

Q: What is the difference between CD15FD181FO3 and CD15FD181FO3F?

A: The primary difference is regulatory compliance. The CD15FD181FO3 is RoHS non-compliant and REACH Affected. The CD15FD181FO3F is ROHS3 Compliant and REACH Unaffected. All electrical and mechanical parameters are identical. Selection depends on application regulatory requirements.

Q: Which substitute part should be selected for new designs?

A: Selection is based on regulatory requirements. For applications requiring RoHS3 compliance or REACH compliance, the CD15FD181FO3F is appropriate. For applications without these requirements, either CD15FD181FO3 or CD15FD181FO3F may be selected based on availability and supply chain considerations.

Q: Are all parts manufactured by the same company?

A: Yes. All three parts (CM05FD181FO3, CD15FD181FO3, and CD15FD181FO3F) are manufactured by Cornell Dubilier Electronics (CDE). The CM05 and CD15 designations indicate different product series within the CDE mica capacitor portfolio.

Q: What is the moisture sensitivity level for these parts?

A: The CM05FD181FO3 has Moisture Sensitivity Level (MSL) of 1 (Unlimited). The CD15FD181FO3 and CD15FD181FO3F have MSL listed as Not Applicable, indicating these parts do not require moisture-sensitive device handling protocols.
