Frequently Asked Questions (FAQ)

Q: Can CD5CC100DO3 be used as a direct replacement for CMR03C100DOCM?

A: CD5CC100DO3 is electrically and mechanically equivalent to CMR03C100DOCM. However, CD5CC100DO3 is RoHS non-compliant and REACH affected, while CMR03C100DOCM is RoHS3 compliant and REACH unaffected. Use CD5CC100DO3 only in applications where RoHS3 and REACH compliance are not required.

Q: What is the difference between CD5CC100DO3 and CD5CC100DO3F?

A: Both parts are electrically and mechanically identical with 10 pF capacitance, ±0.5 pF tolerance, and 300 V rating. The primary difference is compliance status: CD5CC100DO3F is RoHS3 compliant and REACH unaffected, while CD5CC100DO3 is RoHS non-compliant and REACH affected.

Q: Are all substitute parts physically interchangeable with CMR03C100DOCM?

A: Yes. All substitute parts share identical physical dimensions (0.272" L x 0.110" W), height (0.189" max), lead spacing (0.118" / 3.00 mm), and radial through-hole mounting configuration. They are physically interchangeable on printed circuit boards.

Q: Which substitute part has the highest inventory availability?

A: CMR03C100DOCR has the highest inventory with 1163 units in stock, followed by CD5CC100DO3F with 1047 units.
