Parameter Comparison

Engineering Selection Recommendations

Both CMR03C6R0DOCM and CD5CC060DO3F are Active status components manufactured by Cornell Dubilier Electronics with full RoHS3 compliance and REACH unaffected designation. Selection between these parts is based on availability and supply chain requirements rather than electrical or mechanical differentiation.

CMR03C6R0DOCM (CMR Series): 837 units in stock. Primary selection for new designs and standard procurement.

CD5CC060DO3F (CD5 Series): 884 units in stock. Alternative selection for supply continuity or inventory management. Functionally interchangeable in all circuit applications.

Both components satisfy high-reliability requirements with MSL Rating 1 (Unlimited moisture sensitivity level) and operate across the full -55°C to 125°C temperature range. PCB layout and footprint compatibility is assured due to identical lead spacing and physical dimensions.

Frequently Asked Questions (FAQ)

Q: Can CD5CC060DO3F be used as a direct replacement for CMR03C6R0DOCM in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (6 pF, ±0.5 pF tolerance, 300 V rating), mechanical configuration (radial through-hole, 3.00 mm lead spacing), and compliance certifications (RoHS3, REACH unaffected). No circuit redesign or PCB modification is required.

Q: Are there any differences in temperature stability or frequency response between these parts?

A: No differences are specified in the provided parameters. Both components operate across -55°C to 125°C and utilize mica dielectric material. Frequency response characteristics are not provided in the input data.

Q: What is the significance of the different series designations (CMR vs. CD5)?

A: Series designation indicates internal product line classification within Cornell Dubilier Electronics. Both series meet identical electrical and mechanical specifications for this 6 pF, 300 V application. Series designation does not affect functional performance or compatibility.

Q: Are both parts suitable for high-frequency RF applications?

A: Both parts are specified as General Purpose mica capacitors. Specific high-frequency performance characteristics are not provided in the input parameters. Application suitability must be determined through circuit analysis and frequency response requirements.

Q: What is MSL Rating 1 (Unlimited)?

A: MSL Rating 1 indicates the component has unlimited shelf life and does not require moisture-controlled storage or baking procedures prior to soldering. Both parts can be stored under standard warehouse conditions without degradation.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Identical lead spacing (0.118" / 3.00 mm), physical dimensions (0.272" L x 0.110" W), and maximum seated height (0.189") ensure direct footprint compatibility. No PCB layout modifications are necessary.
