Engineering Selection Recommendations

The Z8F082APB020SG is a direct functional equivalent to the Z8F082APB020SC with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

Product Status: The Z8F082APB020SC is Obsolete, while the Z8F082APB020SG maintains Active status. For new designs or long-term production support, the Z8F082APB020SG is the preferred choice.

Regulatory Compliance: The Z8F082APB020SG is ROHS3 Compliant, whereas the Z8F082APB020SC is RoHS non-compliant. Applications subject to RoHS directives or customer compliance requirements must use the Z8F082APB020SG.

Packaging: The Z8F082APB020SG is supplied in Tube packaging, compared to the Z8F082APB020SC with unspecified packaging. Verify packaging requirements for your procurement and assembly processes.

Inventory Availability: The Z8F082APB020SG has higher current stock availability (1130 Pcs) compared to the Z8F082APB020SC (715 Pcs), supporting supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the Z8F082APB020SG replace the Z8F082APB020SC in existing designs?

A: Yes. Both devices are functionally identical across all electrical and mechanical parameters, including processor architecture, memory configuration, clock speed, supply voltage, peripheral set, and package form factor. Direct substitution is supported without design modifications.

Q: What is the difference between these two part numbers?

A: The primary differences are product status (Obsolete vs. Active), RoHS compliance (non-compliant vs. ROHS3 Compliant), and packaging specification (unspecified vs. Tube). Electrical and functional specifications are identical.

Q: Are there any compatibility concerns with the 8-DIP package?

A: No. Both parts use identical 8-DIP Through Hole packaging (0.300", 7.62mm). PCB layouts, socket compatibility, and assembly processes remain unchanged.

Q: Which part should be selected for new production?

A: The Z8F082APB020SG is recommended for new production due to Active product status, ROHS3 compliance, and superior inventory availability.

Q: Is the Z8F082APB020SG suitable for applications requiring RoHS compliance?

A: Yes. The Z8F082APB020SG is ROHS3 Compliant and meets regulatory requirements for RoHS-restricted applications. The Z8F082APB020SC does not meet these requirements.

Q: Are the supply voltage and operating temperature ranges identical?

A: Yes. Both devices operate at 2.7V to 3.6V supply voltage and 0°C to 70°C operating temperature range. No design adjustments are required for power supply or thermal management.
