Substitute Part Grouping Explanation

Substitution of the Z8F082ASB020SC is determined by strict equivalence across the following critical parameters:

• Core processor architecture (eZ8)
• Core size (8-Bit)
• Operating frequency (20MHz)
• Program memory capacity and type (8KB FLASH)
• RAM capacity (1K x 8)
• Supply voltage range (2.7V ~ 3.6V)
• Peripheral feature set (IrDA, UART/USART, PWM, temperature sensor, watchdog timer, analog-to-digital conversion)
• I/O pin count (6)
• Package type and dimensions (8-SOIC)
• Operating temperature range (0°C ~ 70°C)

The Z8F082ASB020SG meets all substitution criteria as a direct equivalent part from the same manufacturer and product series.

Parameter Comparison

Engineering Selection Recommendations

The Z8F082ASB020SG is a direct functional equivalent to the Z8F082ASB020SC with identical electrical and mechanical specifications. The primary distinction is product status: the Z8F082ASB020SC is obsolete, while the Z8F082ASB020SG is active and currently available.

The Z8F082ASB020SG offers improved compliance status, meeting ROHS3 requirements compared to the non-compliant status of the original part. Both parts maintain REACH Unaffected and EAR99 ECCN classifications.

For new designs or ongoing production requiring this microcontroller functionality, the Z8F082ASB020SG is the appropriate selection due to its active product status and enhanced regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Are the Z8F082ASB020SC and Z8F082ASB020SG pin-compatible?

A: Yes. Both parts use the 8-SOIC package with identical pinout, dimensions (0.154" × 3.90mm width), and I/O configuration (6 I/O pins). Direct PCB substitution is possible without layout modification.

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

A: The parts are electrically and functionally identical. The primary differences are product status (obsolete vs. active), RoHS compliance level (non-compliant vs. ROHS3 compliant), and packaging format (unspecified vs. tube).

Q: Can I use the Z8F082ASB020SG as a drop-in replacement?

A: Yes. The Z8F082ASB020SG is a direct substitute with matching core processor, memory configuration, operating frequency, supply voltage, peripheral set, and package specifications. No firmware or hardware modifications are required.

Q: Why is the original part obsolete?

A: Product obsolescence is determined by the manufacturer. The Z8F082ASB020SG remains in active production and provides equivalent functionality for continued system support.

Q: Are there any compliance considerations when switching parts?

A: The Z8F082ASB020SG meets ROHS3 compliance, which may be required for new designs or systems subject to regulatory requirements. The original Z8F082ASB020SC does not meet RoHS standards. Both parts maintain REACH Unaffected status.

Q: What is the inventory status of these parts?

A: The Z8F082ASB020SC has 1123 pieces in stock (new original). The Z8F082ASB020SG has 2000 pieces in stock (new original, tube packaging).
