Engineering Selection Recommendations

Primary Selection - CMR03C100DOCP: The CMR03C100DOCP is the reference part and remains the primary choice for new designs. It is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronics manufacturing.

Recommended Substitute - CD5CC100DO3F: The CD5CC100DO3F is the preferred substitute part. It matches all electrical and mechanical parameters of the CMR03C100DOCP and maintains equivalent compliance certifications (RoHS3 compliant, REACH unaffected). This part offers the highest inventory availability at 1047 pieces.

Alternative Substitute - CMR03C100DOCR: The CMR03C100DOCR is an alternative substitute within the same CMR series. It provides identical electrical and mechanical specifications with RoHS3 compliance and REACH unaffected status. Inventory availability is 1163 pieces.

Conditional Substitute - CD5CC100DO3: The CD5CC100DO3 is electrically and mechanically equivalent but carries RoHS non-compliant and REACH affected designations. This part is suitable only for applications where regulatory compliance is not a requirement or where legacy system maintenance is the objective.

Frequently Asked Questions (FAQ)

Q: Can CD5CC100DO3F be used as a direct replacement for CMR03C100DOCP?

A: Yes. The CD5CC100DO3F is a direct substitute. Both parts share identical capacitance (10 pF), tolerance (±0.5 pF), voltage rating (300 V), operating temperature range (-55°C ~ 125°C), and mechanical dimensions. Both are RoHS3 compliant and REACH unaffected.

Q: What is the difference between CMR03C100DOCP and CMR03C100DOCR?

A: Both parts are from the CMR series and are electrically and mechanically identical. The difference lies in packaging or internal construction details not specified in the provided parameters. Both are RoHS3 compliant and suitable for equivalent applications.

Q: Why is CD5CC100DO3 listed as a substitute if it is RoHS non-compliant?

A: CD5CC100DO3 matches all electrical and mechanical parameters required for functional substitution. However, its RoHS non-compliant and REACH affected status restricts its use to applications where regulatory compliance is not mandated. For new designs or regulated applications, CD5CC100DO3F or CMR03C100DOCR are preferred.

Q: Are all substitute parts through-hole radial packages?

A: Yes. All substitute parts are through-hole mounted radial packages with identical lead spacing (0.118" / 3.00 mm) and physical dimensions (0.272" L x 0.110" W / 6.90 mm x 2.80 mm). They are directly interchangeable on PCBs designed for the CMR03C100DOCP.

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

A: All parts operate across -55°C to 125°C, ensuring performance in industrial and commercial temperature environments.

Q: Do these capacitors require special handling for moisture?

A: No. All parts have Moisture Sensitivity Level (MSL) 1, classified as unlimited moisture sensitivity. Standard handling procedures apply without special moisture control requirements.
