Frequently Asked Questions (FAQ)

Q: Can CWR09MC685KB be used as a direct replacement for CWR09MC685KC? A: Yes. Both parts share identical capacitance (6.8 µF), tolerance (±10%), voltage rating (35 V), package type (2915/7338 Metric), and operating temperature range (-55°C to 125°C). They are direct electrical and mechanical substitutes.

Q: What is the significance of the different part number suffixes (KC vs KB)? A: The suffix differences (KC and KB) represent manufacturer-specific part number variations within the same CWR09 series. Both parts are produced by KYOCERA AVX and meet identical specifications for this application.

Q: Are there any compliance differences between these substitutes? A: No. Both parts have identical RoHS status (non-compliant), MSL rating (3/168 Hours), ECCN classification (EAR99), and HTSUS code (8532.21.0050).

Q: Does the package type affect PCB layout considerations? A: No. Both parts use the 2915 (7338 Metric) package with identical mechanical dimensions (0.285" L x 0.150" W, 0.125" max height), ensuring no PCB layout modifications are required during substitution.

Q: What is the ESR specification, and does it affect part selection? A: ESR (Equivalent Series Resistance) of 1.3 Ohm is specified for the CWR09MC685KB. Both parts operate identically in tantalum capacitor applications within the specified voltage and temperature ranges.
