Substitute Part Grouping Explanation

Substitution eligibility for the Z8F081APB020SC is determined by strict equivalence across the following critical parameters:

• Core Architecture: eZ8 processor family
• Memory Configuration: 8KB FLASH program memory and 1KB RAM
• Operating Frequency: 20MHz
• Supply Voltage Range: 2.7V ~ 3.6V
• I/O Count: 6 pins
• Peripheral Set: Identical feature set including UART/USART, PWM, watchdog timer, and brown-out detection
• Package Type: 8-DIP through-hole form factor
• Pin Compatibility: Mechanical and electrical pin-to-pin compatibility

The Z8F081APB020SG qualifies as a direct substitute, maintaining 100% electrical and mechanical compatibility while differing only in packaging format and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The Z8F081APB020SG is the direct functional equivalent of the Z8F081APB020SC. Selection between these parts should be based on the following factors:

Product Status: The Z8F081APB020SC is classified as Obsolete, while the Z8F081APB020SG maintains Active status. For new designs or systems requiring long-term component availability, the Z8F081APB020SG is the appropriate choice.

Regulatory Compliance: The Z8F081APB020SG meets ROHS3 compliance requirements, whereas the Z8F081APB020SC is RoHS non-compliant. Applications subject to RoHS directives or customer compliance mandates require the Z8F081APB020SG.

Electrical and Mechanical Compatibility: Both parts are pin-for-pin and functionally identical across all specified electrical parameters, memory configuration, peripheral set, and operating conditions. Direct substitution in existing designs is supported without circuit modification.

Inventory and Lead Time: The Z8F081APB020SG currently maintains higher inventory levels (880 Pcs) compared to the Z8F081APB020SC (791 Pcs), providing improved availability for procurement planning.

Frequently Asked Questions (FAQ)

Q: Are the Z8F081APB020SC and Z8F081APB020SG pin-compatible?

A: Yes. Both devices use the 8-DIP (0.300", 7.62mm) through-hole package with identical pin assignments. Direct socket substitution is supported without PCB modification.

Q: Can I use the Z8F081APB020SG as a replacement in existing Z8F081APB020SC designs?

A: Yes. The Z8F081APB020SG is electrically and mechanically equivalent. All electrical specifications, memory configuration, peripheral functionality, and operating parameters are identical. Existing firmware and hardware designs require no modification.

Q: What is the difference between the Z8F081APB020SC and Z8F081APB020SG?

A: The primary differences are product lifecycle status and regulatory compliance. The Z8F081APB020SC is Obsolete and RoHS non-compliant, while the Z8F081APB020SG is Active and ROHS3 compliant. All functional and electrical specifications are identical.

Q: Why is the Z8F081APB020SC marked as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support for this specific part number variant. The Z8F081APB020SG represents the current active equivalent within the same product family.

Q: Are there any performance differences between these parts?

A: No. Both parts operate at 20MHz, provide 8KB FLASH memory, 1KB RAM, and identical peripheral functionality. Performance characteristics are equivalent across all specified operating conditions.

Q: What packaging formats are available for these parts?

A: Both the Z8F081APB020SC and Z8F081APB020SG are supplied in Tube packaging format. The 8-DIP through-hole package remains consistent across both variants.

Q: Can I mix Z8F081APB020SC and Z8F081APB020SG parts in the same production batch?

A: Yes. Since both parts are functionally and electrically identical, they can be used interchangeably in the same design without performance or compatibility issues.
