CM07FD203JO3 Equivalent & Substitute Parts

Part Overview

The CM07FD203JO3 is a 0.02 µF mica capacitor rated at 500 V with radial through-hole mounting, manufactured by Cornell Dubilier Electronics (CDE). This component is currently active in production. Mica capacitors of this specification are critical in high-reliability applications requiring stable capacitance across temperature extremes and low moisture sensitivity. Alternative models become necessary when specific compliance certifications, lead-free requirements, or inventory constraints require substitution while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Direct substitution for the CM07FD203JO3 is based on electrical equivalence and mechanical interchangeability. The critical parameters defining substitution are:

Capacitance: 0.02 µF (exact match required)
Tolerance: ±5% (matches substitute)
Voltage Rating: 500 V (meets or exceeds application requirement)
Dielectric Material: Mica (maintains electrical performance characteristics)
Operating Temperature Range: -55°C to 125°C (supports full operational envelope)
Mounting Type: Through Hole Radial (identical PCB footprint compatibility)
Lead Spacing: 0.437" (11.10 mm) (ensures mechanical fit)
Physical Dimensions: 0.831" L × 0.449" W (maintains board layout compatibility)

The CD30FD203JO3F qualifies as a parametric equivalent because all electrical and mechanical parameters remain identical to the CM07FD203JO3, with the distinction being series designation (CD30 vs. CM07) and compliance status.

Engineering Selection Recommendations

The CM07FD203JO3 and CD30FD203JO3F are electrically and mechanically equivalent. Selection between these parts is determined by regulatory and compliance requirements rather than performance characteristics.

CM07FD203JO3 applies to applications where RoHS non-compliance is acceptable and REACH-affected materials do not present restrictions. This part is suitable for legacy systems, non-regulated markets, or applications exempt from RoHS3 requirements.

CD30FD203JO3F is the appropriate selection for applications requiring RoHS3 compliance and REACH unrestricted status. This part is mandated for new designs targeting European markets, regulated industries (aerospace, medical, military), and original equipment manufacturers with mandatory compliance certifications. Both parts share identical electrical performance, thermal characteristics, and mechanical interchangeability.

Frequently Asked Questions (FAQ)

Q: Are CM07FD203JO3 and CD30FD203JO3F electrically interchangeable?

A: Yes. Both parts are 0.02 µF mica capacitors with identical capacitance, tolerance (±5%), voltage rating (500 V), temperature range (-55°C to 125°C), and dielectric material. Electrical performance is equivalent.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Both parts feature identical through-hole radial mounting, lead spacing (0.437" / 11.10 mm), and physical dimensions (0.831" L × 0.449" W). PCB layout and hole spacing require no modification.

Q: What is the primary difference between these two parts?

A: The primary difference is regulatory compliance status. The CD30FD203JO3F is RoHS3 compliant and REACH unrestricted, while the CM07FD203JO3 is non-compliant with REACH-affected materials. Series designation differs (CD30 vs. CM07), but this reflects manufacturing generation rather than functional capability.

Q: When should I select CD30FD203JO3F over CM07FD203JO3?

A: Select CD30FD203JO3F for applications requiring RoHS3 compliance, REACH unrestricted materials, or designs intended for European distribution. This part is required for regulated industries and new product certifications.

Q: When should I select CM07FD203JO3?

A: Select CM07FD203JO3 when RoHS3 compliance is not a requirement and REACH-affected materials are permitted by application standards or regional regulations. This part supports legacy systems and non-regulated markets.

Q: Are there any thermal or frequency limitations that differ between these parts?

A: No. Both parts operate across the identical temperature range (-55°C to 125°C). As mica capacitors, both exhibit stable capacitance performance across this range with no frequency-dependent restrictions provided in the specification.

Q: Can I substitute these parts without engineering review?

A: Substitution requires verification that compliance status does not conflict with product requirements. For applications without RoHS3 or REACH restrictions, either part is technically valid. For regulated applications, the compliance status must be confirmed against applicable standards.
