Substitute Part Grouping Explanation

Substitution of the PIC16LC72T-04/SS is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part PIC16LC72-04/SS qualifies as a direct equivalent because it maintains identical specifications in the following key areas:

• Core processor architecture (PIC 8-bit)
• Operating frequency (4MHz)
• Program memory capacity and type (4.6KB OTP)
• RAM configuration (128 x 8)
• I/O pin count (22)
• Supply voltage range (2.5V ~ 6V)
• Peripheral feature set (Brown-out Detect/Reset, POR, PWM, WDT)
• Data converter specifications (A/D 5x8b)
• Connectivity protocols (I2C, SPI)
• Physical package (28-SSOP with identical dimensions)
• Compliance certifications (ROHS3, REACH Unaffected)
• Moisture sensitivity rating (MSL 1)

The primary distinction is product status: the main part is obsolete while the substitute is active, ensuring continued availability for component procurement.
