Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on substitution criteria:

Upgrade Substitutes (KYOCERA AVX Series): Parts KAM21BR71H473JM, KAM21BR71H473JT, KGM21NR71H473JM, and KGM21NR71H473JT maintain identical electrical specifications (0.047 µF, ±5%, 50V, X7R) and package dimensions. These parts differ in packaging format (Tape & Reel) and include AEC-Q200 automotive qualification where applicable. KGM21AR72A473JU provides the same capacitance and tolerance with elevated voltage rating (100V) in the same package footprint.

Direct Substitutes (Multi-Manufacturer): Parts from Walsin Technology Corporation (0805B473J500CT), KEMET (C0805C473J5RAC7800), YAGEO (CC0805JRX7R9BB473), and Vishay Vitramon (VJ0805Y473JXACW1BC, VJ0805Y473JXAPW1BC) meet all critical electrical and mechanical parameters: 0.047 µF capacitance, ±5% tolerance, 50V voltage rating, X7R temperature coefficient, and 0805 package configuration. All substitute parts maintain ROHS3 compliance and MSL 1 rating.

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the original 08055C473JAT2P. Selection among direct substitutes depends on supply availability and packaging requirements:

KYOCERA AVX upgrade substitutes (KAM21BR71H473JM, KAM21BR71H473JT, KGM21NR71H473JM, KGM21NR71H473JT) provide continuity within the same manufacturer ecosystem with higher inventory levels. KAM series parts include AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade reliability. KGM21AR72A473JU offers elevated voltage rating (100V) for designs requiring additional voltage margin while maintaining identical capacitance and tolerance specifications.

Multi-manufacturer direct substitutes (Walsin, KEMET, YAGEO, Vishay Vitramon) provide equivalent electrical performance with varying thickness profiles. YAGEO CC0805JRX7R9BB473 and Vishay Vitramon VJ0805Y473JXAPW1BC offer the highest inventory availability (46,471 and 41,051 units respectively), supporting high-volume production requirements. KEMET C0805C473J5RAC7800 is specified for bypass and decoupling applications with 24,253 units in stock.

Frequently Asked Questions (FAQ)

Q: Can KGM21AR72A473JU (100V rating) replace 08055C473JAT2P (50V rating)? A: Yes. The 100V-rated part is electrically compatible as a direct upgrade. Higher voltage rating provides additional safety margin in circuits designed for 50V operation. Verify PCB layout accommodates the increased thickness (0.057" vs. 0.037" maximum).

Q: What is the difference between KAM21BR71H473JM and KAM21BR71H473JT? A: Both parts are electrically identical (0.047 µF, ±5%, 50V, X7R) with AEC-Q200 automotive qualification. The suffix difference (JM vs. JT) indicates packaging or manufacturing date code variations. Both are direct substitutes for the original part.

Q: Are KYOCERA AVX KGM series parts interchangeable with KAM series? A: Yes, within the specified electrical parameters. KGM21NR71H473JM and KGM21NR71H473JT match the original 0.047 µF, 50V, X7R specifications. Thickness varies slightly (0.039" vs. 0.037" maximum), which may affect PCB assembly clearances in space-constrained designs.

Q: Can I use YAGEO CC0805JRX7R9BB473 in place of the original KYOCERA AVX part? A: Yes. YAGEO CC0805JRX7R9BB473 meets all critical electrical specifications (0.047 µF, ±5%, 50V, X7R) and package requirements (0805). Thickness is 0.037" (0.95mm), comparable to the original 0.037" (0.94mm). ROHS3 compliance and MSL 1 rating are maintained.

Q: What packaging formats are available for substitute parts? A: KYOCERA AVX upgrade substitutes are supplied in Tape & Reel (TR) format. Walsin, KEMET, and Vishay Vitramon parts are available in Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® formats. Verify packaging compatibility with assembly equipment specifications.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental and regulatory specifications.
