Substitute Part Grouping Explanation

Substitution eligibility for the CM04CD010DO3 is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Capacitance: 1 pF
• Tolerance: ±0.5 pF
• Voltage Rating: 500 V
• Dielectric Material: Mica

Mechanical Parameters (Must Match Exactly):

• Mounting Type: Through Hole
• Package Configuration: Radial
• Lead Spacing: 0.142 inches (3.60 mm)
• Height - Seated (Max): 0.331 inches (8.40 mm)

Functional Parameters (Must Match Exactly):

• Operating Temperature Range: -55°C to 125°C
• Application Class: General Purpose

The substitute part CD10CD010DO3F meets all electrical and mechanical equivalence criteria. Both parts are manufactured by Cornell Dubilier Electronics and share identical capacitance, voltage rating, tolerance, dielectric material, mounting configuration, and thermal operating range. Physical dimensions are within acceptable tolerance variance for through-hole PCB assembly.

Engineering Selection Recommendations

Primary Part: CM04CD010DO3

The CM04CD010DO3 remains the specified component for applications where the original design documentation and qualification testing reference this part number. This part is active in production with adequate inventory (1,096 units in stock).

Substitute Part: CD10CD010DO3F

The CD10CD010DO3F is a direct electrical and mechanical equivalent suitable for component interchange. This substitute offers the following advantages:

• ROHS3 compliance status, whereas the primary part is RoHS non-compliant
• REACH unaffected status, whereas the primary part is REACH affected
• Identical electrical performance across all specified parameters
• Identical mechanical fit and PCB compatibility
• Active production status with available inventory (752 units in stock)

Selection between these two parts should be based on regulatory compliance requirements applicable to the end application and geographic market. Both parts are functionally interchangeable from an electrical and mechanical standpoint. The CD10CD010DO3F is recommended for new designs or applications subject to RoHS3 or REACH compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can CD10CD010DO3F be used as a direct replacement for CM04CD010DO3 in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical capacitance (1 pF), tolerance (±0.5 pF), voltage rating (500 V), dielectric material (mica), operating temperature range (-55°C to 125°C), mounting type (through hole), package configuration (radial), lead spacing (0.142 inches), and maximum seated height (0.331 inches). PCB layout and assembly processes require no modification.

Q: What is the difference in physical dimensions between these parts?

A: The length dimension differs slightly: CM04CD010DO3 measures 0.358 inches (9.10 mm), while CD10CD010DO3F measures 0.360 inches (9.15 mm). This 0.05 mm difference is within standard manufacturing tolerance and does not affect PCB assembly or component fit. Width and height dimensions are identical.

Q: Why does the CM04CD010DO3 show RoHS non-compliant status while CD10CD010DO3F is ROHS3 compliant?

A: RoHS compliance status reflects the manufacturing process and material composition used by Cornell Dubilier Electronics for each part number. The CD10CD010DO3F was manufactured to meet ROHS3 directives, while the CM04CD010DO3 predates or was produced under different manufacturing specifications. Both parts are functionally identical; compliance status is a regulatory and sourcing consideration.

Q: Are there any electrical performance differences between these two parts?

A: No. Both parts are specified with identical electrical parameters: 1 pF capacitance, ±0.5 pF tolerance, 500 V voltage rating, mica dielectric, and -55°C to 125°C operating temperature range. Electrical performance in circuit operation is equivalent.

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

A: For new designs, CD10CD010DO3F is recommended if the application is subject to RoHS3 or REACH compliance requirements. If no regulatory compliance mandate exists, either part is acceptable based on availability and cost considerations. Both parts are active in production.

Q: Can these parts be mixed in the same production batch?

A: Yes. From an electrical and mechanical standpoint, these parts are interchangeable. However, if design documentation, bill of materials, or regulatory compliance tracking requires a single part number, mixing should be avoided. Consult quality assurance and compliance documentation for your specific manufacturing environment.
