CM05FD181JO3 Equivalent & Substitute Parts

Part Overview

The CM05FD181JO3 is a 180 pF mica capacitor rated for 500 V operation, manufactured by Cornell Dubilier Electronics (CDE) in the CM05 series. This through-hole radial component is designed for general-purpose applications requiring high voltage stability and precision capacitance values. The part is currently active in production with 657 units in stock.

Substitute parts are necessary when the original CM05FD181JO3 becomes unavailable, when RoHS compliance is required for new designs, or when alternative series options from the same manufacturer provide equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CM05FD181JO3 is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 180 pF (exact match required)
• Tolerance: ±5% (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 Equivalence Criteria:

• 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)

Both substitute parts (CD15FD181JO3 and CD15FD181JO3F) meet all electrical and mechanical equivalence criteria. The CD15 series represents an alternative product line from Cornell Dubilier Electronics with identical performance specifications and physical compatibility.

Parameter Comparison

Engineering Selection Recommendations

CM05FD181JO3 (Original Part): Use when legacy design specifications explicitly require the CM05 series designation or when REACH-affected component status is acceptable for the application. This part is RoHS non-compliant and REACH-affected.

CD15FD181JO3 (Parametric Equivalent): Use as a direct substitute when the CM05FD181JO3 is unavailable. This part maintains identical electrical and mechanical specifications. It is RoHS non-compliant and REACH-affected, matching the compliance profile of the original part. Higher inventory availability (1967 units) supports supply chain continuity.

CD15FD181JO3F (Parametric Equivalent with Enhanced Compliance): Use when designs require RoHS3 compliance or REACH-unaffected component status. This variant is electrically and mechanically identical to both the CM05FD181JO3 and CD15FD181JO3 while providing improved regulatory compliance. Inventory availability is 1705 units.

All three parts are manufactured by Cornell Dubilier Electronics and carry the same ECCN (EAR99) and HTSUS (8532.29.0020) classifications.

Frequently Asked Questions (FAQ)

Q: Can CD15FD181JO3 be used as a direct replacement for CM05FD181JO3 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. They share the same capacitance (180 pF), tolerance (±5%), voltage rating (500 V), operating temperature range (-55°C ~ 125°C), mounting type (through hole), package configuration (radial), lead spacing (0.232" / 5.90mm), and physical dimensions (0.461" L x 0.189" W / 11.70mm x 4.80mm). PCB layout and circuit performance remain unchanged.

Q: What is the difference between CD15FD181JO3 and CD15FD181JO3F?

A: The electrical and mechanical specifications are identical. The primary difference is regulatory compliance: CD15FD181JO3F is ROHS3 compliant and REACH-unaffected, while CD15FD181JO3 is RoHS non-compliant and REACH-affected. Select CD15FD181JO3F for new designs requiring enhanced environmental compliance.

Q: Are there any physical compatibility issues when substituting these parts?

A: No. All three parts have identical physical dimensions, lead spacing, and maximum seated height. They are fully interchangeable in through-hole PCB designs without layout modifications.

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

A: CD15FD181JO3F is the recommended choice for new designs due to ROHS3 compliance and REACH-unaffected status. For legacy or non-regulated applications, CD15FD181JO3 provides equivalent performance with higher inventory availability.

Q: Do these parts have different moisture sensitivity levels?

A: The CM05FD181JO3 specifies MSL 1 (Unlimited). The CD15FD181JO3 and CD15FD181JO3F list MSL as Not Applicable. This reflects different manufacturer documentation standards but does not indicate functional differences in moisture handling for mica dielectric capacitors.
