Substitute Part Grouping Explanation

Substitution eligibility for the USB2227-NU-05 is determined by strict equivalence across the following critical parameters:

• Identical base product number (USB2227)
• Matching package specification (128-TQFP / 128-VTQFP 14x14)
• Identical supply voltage requirement (3.3V)
• Equivalent RoHS and REACH compliance status
• Same moisture sensitivity classification (MSL 1)
• Surface mount mounting type

The USB2227-NU-11 meets all substitution criteria as a direct equivalent. The primary distinction between these parts is product status and packaging format, with USB2227-NU-11 classified as active and supplied in tray packaging, whereas USB2227-NU-05 is obsolete.
