Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CMR03C1R0DOCP are identified based on strict equivalence of the following parameters:

• Capacitance value: 1 pF
• Tolerance: ±0.5 pF
• Voltage rating: 300 V
• Dielectric material: Mica
• Mounting type: Through Hole (Radial)
• Lead spacing: 0.118" (3.00 mm)
• Physical dimensions: 0.272" L x 0.110" W (6.90 mm x 2.80 mm)
• Height seated maximum: 0.189" (4.80 mm)
• Operating temperature range: -55°C to 125°C

The substitute parts CD5CC010DO3 and CD5CC010DO3F meet all electrical and mechanical parameters required for direct substitution. Both parts are manufactured by Cornell Dubilier Electronics and maintain identical capacitance, voltage rating, tolerance, dielectric material, and physical form factor.

Parameter Comparison

Engineering Selection Recommendations

CMR03C1R0DOCP is the primary reference part with Active product status and ROHS3 compliance. This part is suitable for applications requiring full regulatory compliance with RoHS3 and REACH unaffected status.

CD5CC010DO3F is the preferred substitute when CMR03C1R0DOCP is unavailable. This part maintains identical electrical and mechanical specifications, Active product status, ROHS3 compliance, and REACH unaffected status. Inventory availability is higher (1748 pcs vs. 669 pcs).

CD5CC010DO3 is an alternative substitute with identical electrical and mechanical specifications and Active product status. However, this part is RoHS non-compliant and REACH affected. Selection of this part requires confirmation that regulatory compliance requirements do not apply to the end application.

All three parts are functionally equivalent for circuits requiring 1 pF capacitance at 300 V with mica dielectric and radial through-hole mounting.

Frequently Asked Questions (FAQ)

Q: Can CD5CC010DO3 be used as a direct replacement for CMR03C1R0DOCP?

A: CD5CC010DO3 meets all electrical and mechanical specifications for direct substitution. However, it is RoHS non-compliant and REACH affected, whereas CMR03C1R0DOCP is ROHS3 compliant and REACH unaffected. Selection depends on regulatory requirements of the end application.

Q: What is the difference between CD5CC010DO3 and CD5CC010DO3F?

A: Both parts are electrically and mechanically identical with 1 pF capacitance, 300 V rating, mica dielectric, and radial through-hole configuration. The primary difference is regulatory compliance: CD5CC010DO3F is ROHS3 compliant and REACH unaffected, while CD5CC010DO3 is RoHS non-compliant and REACH affected. CD5CC010DO3F also has higher inventory availability.

Q: Are the physical dimensions identical across all three parts?

A: Yes. CMR03C1R0DOCP, CD5CC010DO3, and CD5CC010DO3F all share identical dimensions of 0.272" L x 0.110" W (6.90 mm x 2.80 mm), maximum seated height of 0.189" (4.80 mm), and lead spacing of 0.118" (3.00 mm). All are suitable for the same PCB footprint.

Q: What is the operating temperature range for these capacitors?

A: All three parts operate across -55°C to 125°C, providing equivalent thermal performance for general-purpose applications.

Q: Are there any differences in moisture sensitivity?

A: No. All three parts have Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity concerns during storage or handling.

Q: Which part should be selected for new designs?

A: For new designs, CD5CC010DO3F is recommended. It provides ROHS3 compliance, REACH unaffected status, and higher inventory availability while maintaining full electrical and mechanical equivalence to CMR03C1R0DOCP.
