CM07FD103JO3 Equivalent & Substitute Parts

Part Overview

The CM07FD103JO3 is a 10000 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 dielectric performance. The part is currently active in production with 1051 units in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same product category. Substitution becomes necessary due to inventory availability, compliance requirements, or manufacturing transitions between product series.

Substitute Part Grouping Explanation

Substitution for the CM07FD103JO3 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 10000 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating: 500 V (exact match required)
• Dielectric Type: Mica (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Mounting Configuration: Through Hole Radial (exact match required)
• Physical Dimensions: Lead spacing 0.437" (11.10mm), overall dimensions 0.799" L x 0.339" W, height 0.890" maximum (exact match required)

The substitute parts CD30FD103JO3 and CD30FD103JO3F are from the CD30 series and maintain all electrical and mechanical parameters identical to the CM07FD103JO3. Both parts are manufactured by Cornell Dubilier Electronics and are pin-compatible for direct board-level replacement.

Parameter Comparison

Engineering Selection Recommendations

All three parts—CM07FD103JO3, CD30FD103JO3, and CD30FD103JO3F—are electrically and mechanically equivalent for direct substitution in applications requiring a 10000 pF, 500 V mica capacitor with radial through-hole mounting.

Compliance Considerations:

The CD30FD103JO3F variant offers ROHS3 compliance and REACH unaffected status, making it the preferred choice for applications subject to European Union environmental regulations. The CM07FD103JO3 and CD30FD103JO3 are RoHS non-compliant and REACH affected, suitable for applications without such regulatory constraints.

Inventory and Availability:

Selection between these parts may be driven by stock availability. The CM07FD103JO3 has 1051 units in stock, CD30FD103JO3F has 1039 units, and CD30FD103JO3 has 846 units available.

Series Transition:

The CD30 series represents a product line evolution from the CM07 series. Both series maintain identical electrical and mechanical specifications for this capacitance value and voltage rating.

Frequently Asked Questions (FAQ)

Q: Can CD30FD103JO3 and CD30FD103JO3F be used interchangeably with CM07FD103JO3?

A: Yes. All three parts maintain identical capacitance (10000 pF), tolerance (±5%), voltage rating (500 V), operating temperature range (-55°C ~ 125°C), and physical dimensions. They are pin-compatible for direct board-level replacement.

Q: What is the difference between CD30FD103JO3 and CD30FD103JO3F?

A: The primary differences are compliance certifications. CD30FD103JO3F is ROHS3 compliant and REACH unaffected, while CD30FD103JO3 is RoHS non-compliant and REACH affected. Electrical and mechanical parameters are identical.

Q: Are there any physical dimension differences between these parts?

A: No. All three parts share identical dimensions: 0.799" L x 0.339" W (20.30mm x 8.60mm), lead spacing of 0.437" (11.10mm), and maximum seated height of 0.890" (22.60mm). They fit the same PCB footprint.

Q: Which part should I select for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 and REACH compliance, use CD30FD103JO3F. For applications without such requirements, any of the three parts is suitable based on availability.

Q: Is the CM07 series being discontinued?

A: The CM07FD103JO3 remains active in production. However, the CD30 series represents the current product line for mica capacitors in this specification range.

Q: Can these parts be used in high-temperature applications?

A: Yes. All three parts are rated for operation across the -55°C ~ 125°C temperature range, suitable for industrial and high-temperature environments within this specification.
