Substitute Part Grouping Explanation

Substitution eligibility for the Z8F012APJ020EC is determined by strict equivalence across the following critical parameters:

• Processor Architecture: eZ8 core processor
• Memory Configuration: 1KB FLASH, 256 bytes RAM, 16 bytes EEPROM
• Operating Frequency: 20MHz
• Supply Voltage Range: 2.7V ~ 3.6V
• Package Type: 28-DIP through-hole configuration
• I/O Count: 23 pins
• Peripheral Set: Identical feature set including PWM, temperature sensor, watchdog timer, and communication interfaces

The Z8F012APJ020EG2156 meets all substitution criteria as a direct functional equivalent with identical electrical and mechanical specifications. The primary distinction is product status and compliance certification.

Engineering Selection Recommendations

The Z8F012APJ020EG2156 is the direct substitute for the Z8F012APJ020EC. Selection between these parts should be based on the following factors:

Product Status: The Z8F012APJ020EC is obsolete, while the Z8F012APJ020EG2156 maintains active product status with ongoing manufacturer support and availability.

Regulatory Compliance: The Z8F012APJ020EG2156 is ROHS3 compliant, whereas the Z8F012APJ020EC is RoHS non-compliant. For applications subject to RoHS directives or environmental regulations, the Z8F012APJ020EG2156 is the required choice.

Packaging: Both parts are supplied in 28-DIP through-hole packages. The Z8F012APJ020EG2156 is supplied in tube packaging, while the Z8F012APJ020EC packaging specification is not provided.

Functional Equivalence: Both parts are electrically and mechanically identical across all specified parameters, ensuring direct pin-for-pin and code-level compatibility.

Frequently Asked Questions (FAQ)

Q: Are Z8F012APJ020EC and Z8F012APJ020EG2156 pin-compatible?

A: Yes. Both parts use the 28-DIP package with identical pinout, voltage specifications, and I/O configuration. Direct socket substitution is possible without PCB modification.

Q: Can firmware developed for Z8F012APJ020EC run on Z8F012APJ020EG2156?

A: Yes. Both devices feature identical eZ8 core processors, memory configurations, and peripheral sets. Firmware compiled for one part executes without modification on the other.

Q: What is the significance of the product status difference?

A: The Z8F012APJ020EC is classified as obsolete, indicating Zilog has discontinued manufacturing and support. The Z8F012APJ020EG2156 maintains active status with ongoing availability and manufacturer technical support.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical or functional characteristics. Both parts meet identical electrical specifications.

Q: Are there inventory considerations between these parts?

A: Both parts are available in stock. The Z8F012APJ020EC has 763 units available, while the Z8F012APJ020EG2156 has 795 units available. For new designs or long-term support, the active-status Z8F012APJ020EG2156 is recommended.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the design does not specifically require the obsolete part number for traceability or documentation purposes. The Z8F012APJ020EG2156 is a direct functional replacement.
