Substitute Part Grouping Explanation

Substitution of the CD10ED270JO3F is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance Value: 27 pF (exact match required)
• Voltage Rating: 500 V (exact match required)
• Tolerance: ±5% (exact match required)
• Dielectric Type: Mica (exact match required)
• Mounting Configuration: Through Hole Radial (exact match required)
• Physical Dimensions: 0.370" L x 0.189" W with 0.142" lead spacing (exact match required)
• Temperature Range: -55°C ~ 125°C (exact match required)

The CM04ED270JO3 from Cornell Dubilier Electronics meets all electrical and mechanical equivalence criteria. Both parts share identical capacitance, voltage rating, tolerance, dielectric material, mounting type, package configuration, lead spacing, and operating temperature specifications. Differences exist in series designation (CD10 versus CM04), RoHS compliance status, and regulatory classifications, which do not affect electrical or mechanical interchangeability.

Engineering Selection Recommendations

Primary Selection: CD10ED270JO3F

The CD10ED270JO3F is the recommended primary selection. This part carries ROHS3 compliance certification, which aligns with current regulatory requirements in most manufacturing jurisdictions. The part is in active production status with adequate inventory availability (1144 units).

Substitute Selection: CM04ED270JO3

The CM04ED270JO3 is electrically and mechanically equivalent and serves as a direct substitute when CD10ED270JO3F availability is constrained. This part is also in active production status with 1099 units in inventory. However, the CM04ED270JO3 is classified as RoHS non-compliant and REACH Affected. Selection of this substitute requires verification that the end application and regulatory environment permit use of non-compliant components. Both parts share identical electrical performance, physical dimensions, and thermal operating characteristics.

Frequently Asked Questions (FAQ)

Q: Can CM04ED270JO3 be used as a direct replacement for CD10ED270JO3F in PCB assembly?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical capacitance (27 pF), voltage rating (500 V), tolerance (±5%), dielectric material (mica), mounting type (through hole radial), lead spacing (0.142"), and physical dimensions (0.370" L x 0.189" W). PCB footprints and circuit performance are identical.

Q: What is the difference between the CD10 and CM04 series?

A: The CD10 and CM04 are different product series from Cornell Dubilier Electronics. Both series contain equivalent 27 pF, 500 V mica capacitors with identical electrical and mechanical specifications. The primary difference is regulatory compliance status: CD10ED270JO3F is ROHS3 compliant, while CM04ED270JO3 is RoHS non-compliant.

Q: Are there any temperature or voltage derating considerations when substituting between these parts?

A: No. Both parts operate across the identical temperature range (-55°C ~ 125°C) and carry the same voltage rating (500 V). No derating adjustments are required when substituting between CD10ED270JO3F and CM04ED270JO3.

Q: Which part should be selected for new designs?

A: CD10ED270JO3F is the recommended selection for new designs due to ROHS3 compliance certification. This ensures alignment with current and future regulatory requirements across most manufacturing regions and end markets.

Q: Can these parts be used interchangeably in existing assemblies?

A: Yes, provided the existing assembly does not have specific regulatory or compliance requirements that mandate RoHS compliance. If the assembly is subject to RoHS regulations, CD10ED270JO3F must be used. If RoHS compliance is not a requirement, either part may be used without affecting electrical or mechanical performance.
