Applications

Equivalent & Alternatives

When evaluating 293D477X9010E2TE3 equivalent devices, engineers should compare capacitance, voltage rating, capacitance tolerance, ESR, leakage current, ripple-current capability, E case footprint, termination finish, and reel-packaging requirements.

Compared with 293D477X0010E2TE3, 293D477X9010E2TE3 is optimized for the same 470 μF / 10 VDC E case design but with ±10 % capacitance tolerance. 293D477X9010E2TE3 vs 293D477X9010E2WE3 selection depends mainly on production reel format, while 293D477X9010E2TE3 vs 293D477X9010E2DE3 selection depends on whether dry-pack handling is required.
