CM04FD101FO3 Equivalent & Substitute Parts

Part Overview

The CM04FD101FO3 is a 100 pF mica capacitor rated for 500 V operation, manufactured by Cornell Dubilier Electronics (CDE). This through-hole radial component is designed for general-purpose applications requiring high voltage and stable capacitance performance across a wide temperature range (-55°C to 125°C). The part is currently active in production with 706 units in stock.

Identifying equivalent and substitute parts is necessary when the primary part becomes unavailable, when supply chain optimization is required, or when design revisions necessitate component alternatives that maintain identical electrical and mechanical performance characteristics.

• Voltage rating: 500 V (exact match required)
• Dielectric material: Mica (exact match required)

Mechanical Parameters:

• Mounting type: Through Hole (exact match required)
• Package configuration: Radial (exact match required)
• Lead spacing: 0.142" / 3.60 mm (exact match required)
• Physical dimensions: 0.370" L x 0.201" W / 9.40 mm x 5.10 mm (exact match required)
• Maximum seated height: 0.350" / 8.90 mm (exact match required)

Environmental Parameters:

• Operating temperature range: -55°C to 125°C (exact match required)

The substitute part CD10FD101FO3F meets all electrical, mechanical, and environmental criteria for direct substitution with the CM04FD101FO3.

Parameter Comparison

Engineering Selection Recommendations

Both the CM04FD101FO3 and CD10FD101FO3F are active production components manufactured by Cornell Dubilier Electronics. The parts are electrically and mechanically identical across all specified parameters.

Compliance Considerations:

The CM04FD101FO3 is RoHS non-compliant and REACH Affected. The CD10FD101FO3F is RoHS3 Compliant and REACH Unaffected. Selection between these parts should be based on the regulatory requirements of the end application and target market. Applications requiring RoHS3 compliance must use CD10FD101FO3F. Applications without RoHS compliance requirements may use either part.

Both parts carry ECCN classification EAR99 and HTSUS code 8532.29.0020, indicating identical export and tariff treatment.
