Substitute Part Grouping Explanation

Substitution eligibility for the Z8F021APH020EC is determined by strict equivalence across the following critical parameters:

• Core processor architecture (eZ8)
• Memory configuration (2KB FLASH, 512 bytes RAM, 64 bytes EEPROM)
• Operating frequency (20MHz)
• Supply voltage range (2.7V ~ 3.6V)
• I/O count (17 pins)
• Connectivity features (IrDA, UART/USART)
• Peripheral set (Brown-out Detect/Reset, LED, LVD, POR, PWM, WDT)
• Package type (20-DIP)
• Operating temperature range (-40°C ~ 105°C)

The Z8F021APH020EG2156 meets all these criteria and represents the active production equivalent with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The Z8F021APH020EG2156 is the direct functional equivalent for the obsolete Z8F021APH020EC. Both parts share identical electrical specifications, memory configuration, and package geometry, ensuring pin-for-pin compatibility in existing circuit designs.

The primary distinction lies in product status and regulatory compliance. The Z8F021APH020EG2156 is in active production status, providing assured long-term availability and supply chain continuity. Additionally, the substitute part carries ROHS3 compliance certification, whereas the original part is RoHS non-compliant. Both parts maintain REACH Unaffected status and EAR99 export classification.

For new designs or system refreshes, the Z8F021APH020EG2156 is the appropriate selection. For legacy system maintenance requiring the exact original part specification, the Z8F021APH020EC remains available in limited inventory (772 pieces).

Frequently Asked Questions (FAQ)

Q: Are Z8F021APH020EC and Z8F021APH020EG2156 pin-compatible?

A: Yes. Both parts use the 20-DIP (0.300", 7.62mm) package with identical pin assignments, I/O configuration (17 pins), and electrical characteristics. Direct socket substitution is possible without circuit 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) and RoHS compliance (non-compliant vs. ROHS3 compliant). The Z8F021APH020EG2156 represents the current production equivalent.

Q: Can I use Z8F021APH020EG2156 in place of Z8F021APH020EC?

A: Yes. The substitute part meets all electrical, memory, connectivity, and package specifications of the original. Existing firmware and circuit designs require no modification.

Q: Why is the original part marked obsolete?

A: The Z8F021APH020EC has been superseded by the Z8F021APH020EG2156 in Zilog's product portfolio. The substitute maintains full functional equivalence while offering improved regulatory compliance and active manufacturing support.

Q: Are there packaging differences?

A: The original part specification does not indicate packaging type. The substitute is supplied in Tube packaging. Both use the same 20-DIP physical form factor and are suitable for through-hole PCB assembly.

Q: What is the inventory status?

A: Z8F021APH020EC: 772 pieces available (new original). Z8F021APH020EG2156: 1137 pieces available (new original, active production).
