Engineering Selection Recommendations

Primary Recommendation - Active Status Parts:

For new production and ongoing designs, select from parts with "Active" product status:

MAASE168SB7473KTNA01 (Taiyo Yuden MAAS series) - Direct Taiyo Yuden replacement with active status
MCASE168SB7473KTNA01 (Taiyo Yuden MCAS series) - Direct Taiyo Yuden replacement with active status
AC0603KRX7R7BB473 (YAGEO AC series) - Highest inventory availability (21,608 pcs), active status, suitable for high-volume applications
GCJ188R71C473KA01D (Murata Electronics GCJ series) - Active status with soft termination feature for boardflex-sensitive applications
CL10B473KO8VPJC (Samsung Electro-Mechanics CL series) - Active status with soft termination feature
CL10B473KO8WPNC (Samsung Electro-Mechanics CL series) - Active status with open mode failure characteristic

Secondary Recommendation - Inventory Depletion:

When primary options are unavailable:

CGJ3E2X7R1C473K080AA (TDK Corporation CGJ series) - Marked as Obsolete but maintains 7,288 pcs inventory. Use only for legacy system support or when no active alternatives are available.

Compliance Verification:

All listed substitutes maintain:

ROHS3 compliance
AEC-Q200 automotive rating
Moisture Sensitivity Level 1 (Unlimited)
Operating temperature range -55°C ~ 125°C
Identical electrical and mechanical specifications

Selection between active alternatives depends on supply chain availability, cost considerations, and specific application requirements (boardflex sensitivity, failure mode preference).
