Engineering Selection Recommendations

Direct Equivalents (Same Electrical Specifications): KAM21BR71H472KM and KAM21BR71H472KT are direct functional equivalents with identical electrical parameters and AEC-Q200 automotive qualification. These parts are suitable for applications requiring automotive-grade reliability.

Voltage Upgrade Options: 0805PC472KAT1A and KGM21AR72E472JU provide 250V rating, suitable for circuits requiring higher voltage margin. KGM21NR72A472JT and KGM21NR72A472KM provide 100V rating as an intermediate upgrade option.

Tolerance Improvement: KGM21NR71H472JT, KGM21AR72E472JU, KGM21NR72A472JT offer ±5% tolerance compared to the ±10% specification of the main part, providing tighter capacitance control where circuit performance demands improved accuracy.

Packaging Consideration: All substitute parts are supplied in Tape & Reel (TR) format. The main part 08055C472KAT2P packaging format is not specified in the provided data. Verify packaging compatibility with assembly equipment before selection.

Compliance Status: All listed parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage-rated capacitor as a substitute? A: Yes. A capacitor rated at 100V, 250V, or higher can replace the 50V part in the same circuit. Higher voltage ratings provide additional safety margin and do not degrade circuit performance when the actual operating voltage remains at or below 50V.

Q: What is the difference between ±10% and ±5% tolerance? A: Tolerance defines the acceptable deviation from the nominal 4700 pF value. ±10% allows 4230–5170 pF; ±5% allows 4465–4935 pF. Tighter tolerance (±5%) is beneficial for precision circuits but is not required for general-purpose applications.

Q: Are automotive-rated parts (AEC-Q200) required for my application? A: AEC-Q200 qualification is required only for automotive applications. For general-purpose or industrial use, non-automotive-rated equivalents are functionally suitable.

Q: Does package thickness affect PCB assembly? A: Physical thickness variations (0.037" to 0.057") are within standard 0805 component tolerances and do not affect PCB assembly compatibility. Verify with your assembly process specifications if height-constrained designs are involved.

Q: Can I substitute parts from different series (KAF, KAM, KGM)? A: Yes, provided all electrical parameters match the substitution criteria. Different series designations reflect manufacturing process variations but maintain equivalent electrical performance when specifications align.

Q: Is the 0805 package footprint identical across all listed parts? A: Yes. All parts use the 0805 (2012 Metric) package with identical land pattern dimensions (0.079" L x 0.049" W). PCB footprints are interchangeable.
