Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CMR03C3R0DOCM are identified based on strict equivalence of the following parameters:

• Capacitance value: 3 pF
• Tolerance: ±0.5 pF
• Voltage rating: 300 V
• Dielectric material: Mica
• Mounting type: Through Hole
• Package configuration: Radial
• Lead spacing: 0.118" (3.00 mm)
• Physical dimensions: 0.272" L x 0.110" W (6.90 mm x 2.80 mm)
• Maximum seated height: 0.189" (4.80 mm)
• Operating temperature range: -55°C to 125°C

The substitute parts CD5CC030DO3F and CD5CC030DO3 from the CD5 series maintain all electrical and mechanical parameters identical to the main part. Substitution eligibility is determined solely by matching these specified parameters without deviation.

Parameter Comparison

Engineering Selection Recommendations

CD5CC030DO3F is the preferred substitute for CMR03C3R0DOCM. Both parts maintain identical electrical and mechanical specifications. CD5CC030DO3F carries ROHS3 compliance and REACH Unaffected status, matching the regulatory profile of the main part. This part is suitable for direct replacement in applications requiring equivalent capacitance, voltage rating, and physical form factor.

CD5CC030DO3 is an electrical and mechanical equivalent but differs in regulatory compliance. This part is RoHS non-compliant and REACH Affected. Selection of CD5CC030DO3 is restricted to applications where RoHS3 compliance and REACH Unaffected status are not required specifications.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for CMR03C3R0DOCM?

A: Substitution requires matching capacitance (3 pF), tolerance (±0.5 pF), voltage rating (300 V), dielectric material (Mica), mounting type (Through Hole), package configuration (Radial), lead spacing (0.118" / 3.00 mm), physical dimensions (0.272" L x 0.110" W / 6.90 mm x 2.80 mm), and operating temperature range (-55°C to 125°C).

Q: Are CD5CC030DO3F and CD5CC030DO3 electrically identical to CMR03C3R0DOCM?

A: Yes. Both substitute parts maintain identical capacitance, tolerance, voltage rating, dielectric material, temperature range, and all mechanical specifications. Differences exist only in regulatory compliance status.

Q: What is the difference between CD5CC030DO3F and CD5CC030DO3?

A: Both parts are electrically and mechanically equivalent. CD5CC030DO3F is ROHS3 compliant and REACH Unaffected. CD5CC030DO3 is RoHS non-compliant and REACH Affected. Selection depends on regulatory requirements of the application.

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

A: Yes, from a mechanical and electrical standpoint. All three parts share identical lead spacing (0.118" / 3.00 mm), physical dimensions (0.272" L x 0.110" W / 6.90 mm x 2.80 mm), and maximum seated height (0.189" / 4.80 mm). PCB footprints designed for CMR03C3R0DOCM accommodate CD5CC030DO3F and CD5CC030DO3 without modification.

Q: Which substitute should be selected for new designs?

A: CD5CC030DO3F is the appropriate selection for new designs. It maintains full electrical and mechanical equivalence while providing ROHS3 compliance and REACH Unaffected status, aligning with current regulatory standards.
