Substitute Part Grouping Explanation

Substitution of the Z86E4016VSC is determined by strict equivalence across core functional and electrical parameters. The Z86E4016VSG qualifies as a direct substitute based on identical specifications in the following critical areas:

• Z8 core processor architecture
• 8-bit core size
• 16MHz operating frequency
• 4KB OTP program memory configuration
• 236 x 8 RAM allocation
• 32 I/O pin count
• 4.6V to 5.5V supply voltage range
• POR and WDT peripheral support
• Internal oscillator implementation
• 0°C to 70°C operating temperature range
• 44-LCC (J-Lead) surface mount package

The Z86E4016VSG maintains full functional and electrical compatibility with the Z86E4016VSC, differing only in product status classification and packaging format.

Engineering Selection Recommendations

The Z86E4016VSG is the direct functional equivalent for Z86E4016VSC applications. Selection between these parts should be based on regulatory and compliance requirements:

The Z86E4016VSC, classified as obsolete, presents supply continuity risks for new designs and ongoing production. The Z86E4016VSG, with active product status, provides assured long-term availability and supply chain stability.

For applications subject to RoHS3 compliance mandates, the Z86E4016VSG is the required selection due to its ROHS3 Compliant certification. The Z86E4016VSC's RoHS non-compliant status restricts its use in regulated environments.

Both parts maintain identical electrical and functional specifications, ensuring direct pin-for-pin and code-level compatibility. Packaging format differences (tube versus standard packaging) do not affect electrical performance or board-level integration.

Frequently Asked Questions (FAQ)

Q: Can Z86E4016VSG directly replace Z86E4016VSC in existing designs?

A: Yes. The Z86E4016VSG provides complete functional and electrical equivalence. All core specifications—processor architecture, memory configuration, I/O count, voltage range, and operating temperature—are identical. No design modifications are required.

Q: What is the primary reason to transition from Z86E4016VSC to Z86E4016VSG?

A: The Z86E4016VSC is classified as obsolete, creating supply availability concerns. The Z86E4016VSG maintains active product status, ensuring continued availability and supply chain reliability. Additionally, the Z86E4016VSG meets ROHS3 compliance requirements, while the Z86E4016VSC does not.

Q: Are there any pin configuration differences between these parts?

A: No. Both parts use the 44-LCC (J-Lead) surface mount package with identical pin assignments and electrical characteristics.

Q: Does the packaging format difference (tube versus standard) affect compatibility?

A: No. Packaging format affects only handling, storage, and logistics. Electrical performance and board-level integration remain unchanged.

Q: Are firmware or software modifications necessary when substituting Z86E4016VSC with Z86E4016VSG?

A: No. Both parts implement the identical Z8 core processor architecture with matching instruction sets and peripheral configurations. Existing firmware requires no modification.

Q: What compliance certifications apply to each part?

A: Z86E4016VSC is RoHS non-compliant. Z86E4016VSG is ROHS3 Compliant. Both parts are REACH Unaffected and classified under ECCN EAR99.
