Engineering Selection Recommendations

CMR03C3R0DOCP (Primary Part): This part is the preferred selection for applications requiring ROHS3 compliance and REACH unaffected status. It maintains Active product status with full regulatory alignment for modern manufacturing environments.

CD5CC030DO3F (Substitute - Recommended): This part provides full electrical and mechanical equivalence to the CMR03C3R0DOCP with identical ROHS3 compliance and REACH unaffected status. It is suitable for direct replacement in all applications where the primary part is specified. Higher inventory availability (1100 pcs) supports supply chain continuity.

CD5CC030DO3 (Substitute - Conditional): This part maintains electrical and mechanical equivalence but is RoHS non-compliant and REACH affected. Selection of this part is restricted to applications where regulatory compliance requirements do not apply or where legacy system maintenance permits non-compliant components. It is not suitable for new designs or applications subject to RoHS3 or REACH regulations.

Frequently Asked Questions (FAQ)

Q: Can CD5CC030DO3F be used as a direct replacement for CMR03C3R0DOCP?

A: Yes. CD5CC030DO3F maintains identical electrical parameters (3 pF, ±0.5 pF tolerance, 300 V rating), dielectric material (mica), mechanical configuration (radial through-hole), physical dimensions, and environmental specifications. Both parts are ROHS3 compliant and REACH unaffected.

Q: What is the difference between CD5CC030DO3F and CD5CC030DO3?

A: The primary differences are regulatory compliance status. CD5CC030DO3F is ROHS3 compliant and REACH unaffected, while CD5CC030DO3 is RoHS non-compliant and REACH affected. All electrical and mechanical parameters are identical.

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

A: Yes. All three parts share identical dimensions: 0.272" L x 0.110" W (6.90 mm x 2.80 mm) with maximum seated height of 0.189" (4.80 mm), and identical lead spacing of 0.118" (3.00 mm). They are mechanically interchangeable on PCBs designed for radial through-hole 3 pF mica capacitors.

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

A: CD5CC030DO3F is the appropriate selection for new designs. It provides full parametric equivalence to the CMR03C3R0DOCP while maintaining ROHS3 compliance and REACH unaffected status, ensuring alignment with current regulatory requirements.

Q: Can CD5CC030DO3 be used in applications requiring RoHS compliance?

A: No. CD5CC030DO3 is RoHS non-compliant and is not suitable for applications subject to RoHS3 regulations. Use CD5CC030DO3F or CMR03C3R0DOCP for RoHS-compliant applications.

Q: Are there any differences in operating temperature range between the substitute parts?

A: No. All three parts operate across the identical temperature range of -55°C to 125°C with MSL rating of 1 (Unlimited).
