Substitute Part Grouping Explanation

Substitution eligibility for the CMR03C5R0DOCR is determined by strict equivalence across the following critical parameters:

Capacitance Value: 5 pF (exact match required)
Tolerance: ±0.5 pF (exact match required)
Voltage Rating: 300 V (exact match required)
Dielectric Material: Mica (exact match required)
Operating Temperature Range: -55°C to 125°C (exact match required)
Mounting Type: Through Hole (exact match required)
Package Configuration: Radial (exact match required)
Lead Spacing: 0.118" (3.00 mm) (exact match required)
Physical Dimensions: 0.272" L x 0.110" W; Height 0.189" max (exact match required)

All identified substitute parts meet these electrical and mechanical parameters. Differences in RoHS compliance status and REACH classification do not affect functional equivalence but may impact regulatory requirements for specific applications or end markets.

Engineering Selection Recommendations

CMR03C5R0DOCR (Primary Part)

The CMR03C5R0DOCR is ROHS3 compliant and REACH unaffected, making it the preferred selection for applications subject to European Union regulatory requirements or end markets with strict environmental compliance mandates. This part number carries Active product status with 845 units in current inventory.

CD5CC050DO3F (Recommended Substitute)

The CD5CC050DO3F is functionally equivalent to the CMR03C5R0DOCR across all electrical and mechanical parameters. This part is ROHS3 compliant and REACH unaffected, matching the regulatory profile of the primary part. The CD5CC050DO3F carries Active product status with 1829 units in inventory, providing superior supply availability. Selection of this substitute is appropriate when the CMR03C5R0DOCR becomes unavailable.

CD5CC050DO3 (Alternative Substitute)

The CD5CC050DO3 is functionally equivalent to the CMR03C5R0DOCR across all electrical and mechanical parameters. However, this part is RoHS non-compliant and REACH affected. The CD5CC050DO3 is suitable only for applications where regulatory compliance with ROHS3 or REACH is not required. This part carries Active product status with 946 units in inventory.

Frequently Asked Questions (FAQ)

Q: Can CD5CC050DO3F be used as a direct replacement for CMR03C5R0DOCR?

A: Yes. The CD5CC050DO3F is electrically and mechanically equivalent to the CMR03C5R0DOCR. Both parts share identical capacitance (5 pF), tolerance (±0.5 pF), voltage rating (300 V), operating temperature range (-55°C to 125°C), and physical dimensions. Both are ROHS3 compliant and REACH unaffected. Direct substitution is supported without circuit modification.

Q: What is the difference between CD5CC050DO3 and CD5CC050DO3F?

A: The primary difference is regulatory compliance. CD5CC050DO3F is ROHS3 compliant and REACH unaffected, while CD5CC050DO3 is RoHS non-compliant and REACH affected. Electrically and mechanically, both parts are identical. Selection between these two depends on regulatory requirements of the target application or end market.

Q: Are all three parts physically interchangeable?

A: Yes. All three parts (CMR03C5R0DOCR, CD5CC050DO3, and CD5CC050DO3F) share identical physical dimensions, lead spacing, and radial through-hole mounting configuration. They are mechanically interchangeable on printed circuit boards designed for the CMR03C5R0DOCR footprint.

Q: Which substitute part has the best inventory availability?

A: CD5CC050DO3F has the highest inventory level at 1829 units in stock, compared to 845 units for CMR03C5R0DOCR and 946 units for CD5CC050DO3.

Q: Can I use CD5CC050DO3 in an application requiring ROHS3 compliance?

A: No. CD5CC050DO3 is RoHS non-compliant. For applications requiring ROHS3 compliance, use either CMR03C5R0DOCR or CD5CC050DO3F.

Q: Are there any temperature or voltage derating considerations when substituting these parts?

A: No. All three parts operate across the identical temperature range (-55°C to 125°C) and share the same 300 V voltage rating. No derating adjustments are required when substituting between these parts.

Q: What is the lead spacing for these radial capacitors?

A: The lead spacing is 0.118 inches (3.00 mm) for all three parts. This dimension is critical for PCB footprint compatibility.
