Frequently Asked Questions (FAQ)

Q: Can T356A334K035AT replace T356A334K035AS in all applications?

A: Yes. Both parts maintain identical capacitance (0.33 µF), tolerance (±10%), voltage rating (35 V), ESR (15 Ohm), operating temperature range (-55°C ~ 125°C), and mechanical dimensions. The primary difference is RoHS compliance status. Selection depends on regulatory requirements for your application.

Q: What is the difference between these two part numbers?

A: The parts are electrically and mechanically identical. The suffix difference (AS vs. AT) reflects manufacturing compliance variations. T356A334K035AT is ROHS3 compliant, while T356A334K035AS is RoHS non-compliant.

Q: Are the physical dimensions identical?

A: Yes. Both parts share identical radial package dimensions: 0.177" diameter (4.50mm), maximum seated height of 0.339" (8.60mm), and lead spacing of 0.200" (5.08mm). Direct PCB footprint compatibility is confirmed.

Q: Can I use these parts interchangeably on the same circuit board?

A: Yes. Identical electrical parameters (capacitance, voltage, ESR, temperature range) and mechanical specifications (through-hole radial package, dimensions, lead spacing) enable direct substitution without circuit redesign.

Q: Which part should I select for new designs?

A: Selection is based on compliance requirements. For applications requiring ROHS3 compliance, select T356A334K035AT. For applications without RoHS requirements, either part is suitable. Consider inventory availability: T356A334K035AT has 1497 pcs in stock versus 805 pcs for T356A334K035AS.
