Frequently Asked Questions (FAQ)

Q: Can I substitute CL10B122KB8NFNC with a 100V rated capacitor in a 50V circuit?

A: Yes. A 100V rated capacitor is electrically compatible in a 50V circuit. The higher voltage rating provides additional safety margin and does not degrade circuit performance. Examples: 06031C122KAT2A, C0603C122K1RAC7867, 06031C122JAT2A.

Q: What is the difference between ±10% and ±5% tolerance substitutes?

A: Tolerance specifies the allowable deviation from the nominal 1200 pF capacitance value. ±10% allows 1080-1320 pF; ±5% allows 1140-1260 pF. Use ±5% tolerance parts (06035C122JAT2A, 06031C122JAT2A) in precision circuits requiring tighter capacitance control.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 rating, matching the environmental and moisture sensitivity specifications of CL10B122KB8NFNC.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape packaging is supplied in individual strips for manual handling and lower-volume applications. Tape & Reel packaging is supplied on continuous reels for automated assembly. Both formats contain identical components. CL10B122KB8NFNC is supplied in Cut Tape; most substitutes are available in Tape & Reel format.

Q: Can I use a substitute part rated for automotive (AEC-Q200) in a general purpose application?

A: Yes. Automotive-rated parts (CL10B122KB8WPNC, AC0603KRX7R9BB122) meet or exceed general purpose specifications and are fully compatible in non-automotive circuits.

Q: Why is GRM188R72A122KA01D marked "Not For New Designs"?

A: This Murata part is in legacy status, indicating the manufacturer no longer recommends it for new circuit designs. Existing inventory is available, but active alternatives should be prioritized for new projects.

Q: What physical dimension variations exist among substitute parts?

A: All parts conform to 0603 (1608 Metric) package specification. Minor variations occur: length 1.60mm (standard), width 0.80-0.81mm, thickness 0.034-0.036" (0.87-0.92mm). These variations are within package tolerance and do not affect PCB layout or assembly compatibility.

Q: Which substitute offers the highest inventory availability?

A: 06035C122KAT2A (KYOCERA AVX) with 138,927 pcs in stock, followed by C0603C122K5RAC7867 (KEMET) with 125,807 pcs.
