Substitute Part Grouping Explanation

Substitution eligibility for the Z8F042APH020EC is determined by strict equivalence across the following critical parameters:

• Processor Architecture: eZ8 core processor
• Memory Configuration: 4KB FLASH, 1KB RAM, 128 bytes EEPROM
• Operating Frequency: 20MHz
• Supply Voltage Range: 2.7V ~ 3.6V
• I/O Count: 17 pins
• Peripheral Set: Identical feature set including PWM, temperature sensor, watchdog timer, brown-out detection, LVD, and POR
• Data Conversion: A/D 7x10b
• Connectivity: IrDA and UART/USART support
• Package: 20-DIP form factor with 0.300" (7.62mm) pitch
• Mounting: Through-hole technology

The Z8F042APH020EG2156 meets all substitution criteria as a direct functional equivalent with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The Z8F042APH020EG2156 is a direct substitute for the Z8F042APH020EC based on complete electrical and mechanical equivalence. The primary distinction is product lifecycle status: the original part is obsolete while the substitute maintains active product status with current manufacturing support.

The Z8F042APH020EG2156 provides improved compliance posture with ROHS3 certification compared to the non-compliant status of the original part. Both devices share identical functional specifications, memory architecture, peripheral integration, and package form factor, ensuring pin-for-pin and software compatibility.

Selection of the Z8F042APH020EG2156 is appropriate for new designs, system refreshes, and replacement applications where component availability and regulatory compliance are considerations.

Frequently Asked Questions (FAQ)

Q: Are Z8F042APH020EC and Z8F042APH020EG2156 pin-compatible?

A: Yes. Both devices use the 20-DIP package with 0.300" (7.62mm) pitch and identical pin assignments. Direct socket substitution is supported.

Q: What is the functional difference between these parts?

A: There is no functional difference. Both parts implement the eZ8 Encore!® XP® architecture with identical core processor, memory configuration, operating frequency, supply voltage range, I/O count, and peripheral feature set.

Q: Why is the original part marked as obsolete?
