Engineering Selection Recommendations

Direct Substitutes (Same Tolerance ±10%):

KGM21NR71H823KT (KYOCERA AVX): Same manufacturer, ROHS3 compliant, higher inventory availability (35117 Pcs)
C0805C823K5RAC7800 (KEMET): Qualified alternative manufacturer, ROHS3 compliant, standard thickness
CC0805KRX7R9BB823 (YAGEO): Qualified alternative manufacturer, ROHS3 compliant, maximum thickness option

Upgraded Substitutes (Tighter Tolerance ±5%):

KGM21NR71H823JT (KYOCERA AVX): Same manufacturer, improved tolerance, ROHS3 compliant, highest inventory (33996 Pcs)
C0805C823J5RAC7800 (KEMET): Qualified alternative, improved tolerance, ROHS3 compliant
CC0805JRX7R9BB823 (YAGEO): Qualified alternative, improved tolerance, ROHS3 compliant, maximum thickness option

All substitute parts meet the mandatory electrical and mechanical parameters. Selection should prioritize ROHS3 compliance for new designs. Thickness variation (0.037" to 0.057") must be verified against PCB assembly clearance requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 08055C823KAJ2A with a part having ±5% tolerance instead of ±10%? A: Yes. Tighter tolerance (±5%) is an acceptable upgrade and provides improved capacitance accuracy. Parts KGM21NR71H823JT, C0805C823J5RAC7800, and CC0805JRX7R9BB823 offer this specification.

Q: Are all substitute parts physically compatible with the original 0805 footprint? A: Yes. All substitute parts use the 0805 (2012 Metric) package with identical length (0.079") and width (0.049"). Thickness varies from 0.037" to 0.057" and must be verified against PCB assembly clearance.

Q: What is the difference between KYOCERA AVX, KEMET, and YAGEO parts? A: All three manufacturers are qualified suppliers of ceramic capacitors meeting the specified electrical parameters. Selection may be based on supply chain preference, inventory availability, or compliance requirements. KEMET and YAGEO parts are ROHS3 compliant; KYOCERA AVX KGM series are also ROHS3 compliant.

Q: Can I use CC0805KRX7R9BB823 or CC0805JRX7R9BB823 if my PCB has limited vertical clearance? A: No. YAGEO CC series parts have maximum thickness of 0.057" (1.45mm), compared to 0.037" to 0.039" for other options. Verify PCB assembly clearance before selection.

Q: Is the original 08055C823KAJ2A still available for new designs? A: The part is active with 1132 Pcs in stock. However, ROHS3 compliant alternatives with higher inventory are recommended for new designs to ensure long-term supply continuity.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity? A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling, simplifying logistics and assembly processes.
