Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CL21B331JBANNNC are classified based on strict electrical and mechanical parameter alignment:

Direct Equivalent Substitutes maintain identical specifications across all critical parameters: 330 pF capacitance, ±5% tolerance, 50V rated voltage, X7R temperature coefficient, 0805 package, and -55°C ~ 125°C operating temperature range. These parts are interchangeable in circuit applications without design modification.

Upgrade Substitutes maintain the same capacitance, tolerance, temperature coefficient, package, and operating temperature range, but feature elevated voltage ratings (200V vs. 50V). These parts provide enhanced voltage margin and are suitable for applications where the original 50V specification can accommodate higher-rated components without adverse effects.

The substitution logic is determined by:

• Capacitance value (330 pF)
• Tolerance (±5%)
• Temperature Coefficient (X7R)
• Package type (0805 / 2012 Metric)
• Operating temperature range (-55°C ~ 125°C)
• Mounting type (Surface Mount, MLCC)
• Compliance certifications (ROHS3, REACH Unaffected)

Parameter Comparison

Engineering Selection Recommendations

KGM21NR71H331JT (KYOCERA AVX) is a direct equivalent substitute for CL21B331JBANNNC. All critical electrical parameters are identical: 330 pF capacitance, ±5% tolerance, 50V voltage rating, and X7R temperature coefficient. Both parts are ROHS3 compliant, REACH unaffected, and rated for -55°C ~ 125°C operation. Mechanical compatibility is confirmed through identical 0805 package specification. This substitute is suitable for direct replacement in existing designs without circuit modification. Thickness variation (1.00mm vs. 0.75mm) must be evaluated for space-constrained PCB layouts.

C0805C331J2RAC7800 (KEMET) is an upgrade substitute featuring 200V voltage rating while maintaining 330 pF capacitance, ±5% tolerance, X7R temperature coefficient, and 0805 package. This part is ROHS3 compliant and REACH unaffected. The elevated voltage rating provides additional design margin and is applicable in circuits where 50V specification is not a limiting constraint. Thickness (0.88mm) falls between the original part and the KYOCERA AVX alternative. Selection of this upgrade substitute should be based on circuit voltage requirements and available PCB clearance.

All three parts maintain Active product status and identical compliance certifications, ensuring long-term availability and regulatory conformance.

Frequently Asked Questions (FAQ)

Q: Can KGM21NR71H331JT replace CL21B331JBANNNC in all applications?

A: Yes, KGM21NR71H331JT is a direct equivalent substitute. Both parts share identical capacitance (330 pF), tolerance (±5%), voltage rating (50V), temperature coefficient (X7R), package (0805), and operating temperature range (-55°C ~ 125°C). The primary consideration is thickness: KGM21NR71H331JT measures 1.00mm maximum thickness compared to 0.75mm for the original part. PCB layout clearance must be verified before substitution.

Q: When should C0805C331J2RAC7800 be used instead of the original part?

A: C0805C331J2RAC7800 is an upgrade substitute with 200V voltage rating versus 50V for CL21B331JBANNNC. Use this part when circuit design permits higher voltage-rated components or when additional voltage margin is required. Electrical performance remains equivalent at 330 pF capacitance and X7R temperature coefficient. Thickness (0.88mm) is intermediate between the other two options.

Q: Are all three parts mechanically compatible with 0805 footprints?

A: All three parts conform to 0805 (2012 Metric) package specification with length 0.079" (2.00-2.01mm) and width 0.049" (1.25mm). Thickness varies: CL21B331JBANNNC (0.75mm), C0805C331J2RAC7800 (0.88mm), and KGM21NR71H331JT (1.00mm). Standard 0805 footprints accommodate all three parts; however, space-constrained designs may require thickness verification.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. CL21B331JBANNNC, KGM21NR71H331JT, and C0805C331J2RAC7800 are all ROHS3 compliant and REACH unaffected. Moisture sensitivity level is 1 (Unlimited) for all parts. ECCN classification is EAR99 and HTSUS code is 8532.24.0020 across all three parts.

Q: What is the difference between direct equivalent and upgrade substitutes?

A: Direct equivalent substitutes (KGM21NR71H331JT) maintain all specifications identical to the original part, including 50V voltage rating. Upgrade substitutes (C0805C331J2RAC7800) maintain capacitance, tolerance, and temperature coefficient but feature higher voltage rating (200V). Upgrade substitutes provide additional design margin and are suitable when circuit voltage requirements permit higher-rated components.
