Frequently Asked Questions (FAQ)

Q: Can the LFE2-6SE-7FN256C replace the LFE2-6SE-7F256C in existing designs?

A: Yes. Both parts share identical electrical specifications (supply voltage, logic elements, I/O count, RAM capacity) and mechanical specifications (256-BGA package, 17x17 footprint, surface mount). No design changes are required.

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

A: The primary differences are product status and compliance certifications. The LFE2-6SE-7F256C is obsolete and RoHS non-compliant, while the LFE2-6SE-7FN256C is active and ROHS3 compliant. The "N" designation in the part number indicates the updated packaging specification (Tray).

Q: Are there any package or footprint differences?

A: Both parts use the 256-FPBGA (17x17) package with identical pin assignments and mechanical dimensions. The packaging format differs (unspecified versus Tray), but this does not affect PCB layout or assembly compatibility.

Q: What is the operating temperature range for both parts?

A: Both parts operate across 0°C to 85°C junction temperature (TJ), making them suitable for industrial and commercial applications within this thermal envelope.

Q: Why should I select the LFE2-6SE-7FN256C over the obsolete part?

A: The LFE2-6SE-7FN256C offers active product status, ensuring ongoing availability and manufacturer support. ROHS3 compliance meets current regulatory requirements for new designs and production environments.
