Substitute Part Grouping Explanation

Substitution of the Z8674312VSC is determined by strict equivalence across all electrical and mechanical parameters. The substitute part Z8674312VSG maintains identical specifications for core processor architecture, memory configuration, I/O count, voltage supply range, operating temperature, package type, and peripheral functionality. Both parts are manufactured by Zilog within the Z8® series and share the same base product number (Z8674312), confirming functional interchangeability at the component level.

The key parameters governing substitution are:

• Core processor type and architecture (Z8)
• Memory size and type (8KB OTP)
• I/O pin count (32)
• Operating voltage range (4.6V ~ 5.5V)
• Package and pinout (44-LCC J-Lead)
• Peripheral set (POR, WDT)
• Speed rating (12MHz)

Parameter Comparison

Engineering Selection Recommendations

The Z8674312VSG is the direct substitute for the Z8674312VSC. Both components are electrically and mechanically identical across all functional parameters. The primary distinction is product lifecycle status: the Z8674312VSC is obsolete, while the Z8674312VSG maintains active production status with ROHS3 compliance certification. For new designs or system replacements, the Z8674312VSG is the appropriate selection. For legacy system maintenance where the original part number is specified, the Z8674312VSG provides equivalent functionality with improved regulatory compliance. The Z8674312VSG is available in tube packaging, which is standard for production quantities.
