Parameter Comparison

Engineering Selection Recommendations

Both the CDR01BX331BKUP and KGM21NR72A331KT are manufactured by KYOCERA AVX and share identical electrical and mechanical specifications. The primary distinction is regulatory compliance status:

The KGM21NR72A331KT variant provides ROHS3 compliance and REACH Unaffected status, making it suitable for applications requiring these certifications. The main part (CDR01BX331BKUP) remains active and supported by the manufacturer.

Packaging format differs between the two parts: CDR01BX331BKUP is supplied in bulk, while KGM21NR72A331KT is supplied in Tape & Reel format, accommodating different procurement and assembly workflows.

Both parts maintain identical MSL Level 1 classification, supporting unlimited shelf life without moisture bake-out requirements.

Frequently Asked Questions (FAQ)

Can KGM21NR72A331KT directly replace CDR01BX331BKUP in my design?

Yes. Both parts are 0805 (2012 Metric) ceramic capacitors with identical capacitance (330 pF), voltage rating (100V), tolerance (±10%), and temperature coefficient (X7R). Electrical performance and physical form factor are equivalent.

What is the difference in packaging between these two parts?

CDR01BX331BKUP is supplied in bulk packaging, while KGM21NR72A331KT is supplied in Tape & Reel format. This affects procurement quantity options and automated assembly compatibility. The components themselves are electrically and mechanically identical.

Which part should I select if my application requires RoHS compliance?

KGM21NR72A331KT carries ROHS3 compliance certification, while CDR01BX331BKUP is RoHS non-compliant. If regulatory compliance is required, KGM21NR72A331KT is the appropriate selection.

Are there moisture handling differences between these parts?

No. Both parts carry MSL Level 1 classification, indicating unlimited shelf life without moisture sensitivity constraints or required bake-out procedures.

How do the regulatory statuses differ?

KGM21NR72A331KT is REACH Unaffected, while CDR01BX331BKUP is REACH Affected. Both parts carry the same ECCN classification (EAR99) and HTSUS code (8532.24.0020). For applications subject to REACH regulations, KGM21NR72A331KT is the compliant option.
