Frequently Asked Questions (FAQ)

Q: Can the 1111J5000330FQT be used as a direct replacement for the 1111J5000330FUT?

A: Yes. Both parts are manufactured by Knowles Syfer with identical capacitance (33 pF), tolerance (±1%), voltage rating (500V), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), and package dimensions (1111/2828 Metric). The substitute is pin-compatible and functionally equivalent.

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

A: The primary difference is product status. The 1111J5000330FUT is obsolete, while the 1111J5000330FQT is active. The suffix change (FUT to FQT) reflects a manufacturing or specification revision by Knowles Syfer. Electrical and mechanical parameters remain identical.

Q: Are there any compliance or regulatory differences?

A: The 1111J5000330FQT includes documented ROHS3 compliance and REACH unaffected status. Both parts share the same ECCN (EAR99) and HTSUS classification (8532.24.0020), confirming equivalent regulatory treatment.

Q: Will the 1111J5000330FQT fit the same PCB footprint?

A: Yes. Both parts use the 1111 (2828 Metric) package with identical dimensions: 0.110" L × 0.110" W (2.79mm × 2.79mm) and 0.070" maximum thickness (1.78mm). Surface mount placement and reflow parameters remain unchanged.

Q: Is the moisture sensitivity level the same?

A: Yes. Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly.
