Frequently Asked Questions (FAQ)
Can I safely substitute Vishay 293D227X0004B2TE3 for an AVX TAJB227M004RNJ in a 3.3 V rail with 2 A load-step transients without risking brown-out?
The 293D227X0004B2TE3 220 µF/4 V tantalum has 1.5 Ω ESR at 100 kHz—almost triple the TAJB’s 0.6 Ω—so during a 2 A load step you will see ~300 mV extra drop (ΔV=ESR×ΔI). Add 20 % tolerance and you could exceed the 3.3 V rail’s ±5 % window. Solve this by paralleling two 293D227X0004B2TE3 and add a 22 µF X5R ceramic within 5 mm of the load; the composite impedance keeps worst-case delta-V under 120 mV and keeps FIT low thanks to Vishay’s 1 %/1000 h surge-screening.
What is the actual safe ripple-current limit for 293D227X0004B2TE3 at 85 °C so I don’t crack the 3528 case in a Class-D audio amplifier?
With 1.5 Ω ESR the part self-heats ~0.22 °C per 100 mArms. Vishay’s 293D series allows 0.1 W continuous at 85 °C; that equates to 256 mArms. If your audio line draws 400 mA peaks, run two 293D227X0004B2TE3 in parallel and keep each device <200 mA; add 10 mm² copper pour on each pad, keep traces ≥0.5 mm wide, and verify with a 30-min thermal camera test—temperature rise must stay <10 °C.
Will reflowing 293D227X0004B2TE3 on an 8-layer Pb-free board with 260 °C peak violate MSL-1 or create craze cracks in the molded body?
MSL-1 means Vishay guarantees no moisture popcorning, but the 293D body is still epoxy-molded. Limit peak temp to 250 °C and time >217 °C <90 s. Use a 1.5 mm stencil and 60 % solder-paste area to minimize mechanical stress during cooling. After reflow, visually inspect under 10× for meniscus cracks. A 5 °C/s cooling ramp (JEDEC J-STD-020) keeps the 3528 package within safe delta-T and does not affect parametrics.
How many 293D227X0004B2TE3 parts can I stack in parallel to hit 2 mΩ effective ESR for a 1 MHz point-of-load without violating the 4 V rating under −40 % tolerance?
Each 293D227X0004B2TE3 adds 220 µF/1.5 Ω; n=18 yields 2 mΩ (1.5 Ω ÷ 18) and 3.96 mF. Worst-case −20 % tolerance plus −55 °C derating (−15 %) gives 149 µF per cap, still delivering 2.7 mF total. Input surge must stay below 80 % of 4 V (3.2 V). Place pairs on opposite sides of the board, keep loop length <2 mm, and add a 4.7 nF 0402 directly on the load pins to squash the 20 MHz spike.
If I replace a failing 6.3 V 470 µF POSCAP with Vishay 293D227X0004B2TE3 on a 5 V USB-C rail, what lifetime and FIT difference should I expect?
The 293D227X0004B2TE3 is rated only 4 V—you are 25 % above its working voltage, accelerating wear by ~10× per 0.2 V overstress. Expect MTTF of ~5 kh at 40 °C instead of the catalog 100 kh. Swap to the 6.3 V version 293D227X006.3B2TE3 (same 3528 footprint) to restore long-term reliability; FIT drops to <0.1 per 10⁹ h at 5 V, 40 °C while still saving 60 % board area versus the POSCAP.
