Substitute Part Grouping Explanation

Substitution eligibility for the Z8F0423PJ005SC is determined by strict equivalence across the following critical parameters:

• Core Architecture: eZ8 processor family
• Memory Configuration: 4KB FLASH program memory and 1KB RAM
• Electrical Specifications: 5MHz operating frequency and 2.7V–3.6V supply voltage range
• I/O Count: 22 I/O pins
• Peripheral Set: Identical connectivity (IrDA, UART/USART) and integrated functions (PWM, WDT, brown-out detection)
• Package: 28-DIP through-hole form factor
• Temperature Range: 0°C to 70°C operating specification

The Z8F0423PJ005SG2156 meets all these criteria and qualifies as a direct substitute. The primary distinction is product status and packaging configuration, not functional or electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The Z8F0423PJ005SG2156 is the direct functional equivalent of the Z8F0423PJ005SC. Selection between these parts should be based on the following factors:

Product Status: The Z8F0423PJ005SC is classified as obsolete, while the Z8F0423PJ005SG2156 maintains active product status with Zilog. For new designs and long-term supply chain stability, the active part is preferred.

Regulatory Compliance: The Z8F0423PJ005SG2156 is ROHS3 compliant, whereas the Z8F0423PJ005SC is RoHS non-compliant. Applications subject to RoHS regulations require the compliant substitute.

Packaging Configuration: The Z8F0423PJ005SG2156 is supplied in tube packaging, while the Z8F0423PJ005SC uses standard packaging. Tube packaging is suitable for automated assembly processes.

Functional Equivalence: Both parts share identical electrical specifications, memory configuration, I/O count, peripheral set, and operating parameters. No functional differences exist between the two devices.

Frequently Asked Questions (FAQ)

Q: Can the Z8F0423PJ005SG2156 replace the Z8F0423PJ005SC in existing applications?

A: Yes. The Z8F0423PJ005SG2156 is functionally and electrically identical to the Z8F0423PJ005SC. All electrical parameters, memory specifications, I/O configuration, and peripheral functions are equivalent. No design modifications are required for direct substitution.

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 type (standard vs. tube). Functional and electrical specifications are identical.

Q: Are there any pin compatibility concerns?

A: No. Both parts use the 28-DIP (0.600", 15.24mm) package with identical pin assignments and 22 I/O pins. PCB layouts and socket compatibility are fully maintained.

Q: Which part should be selected for new production?

A: The Z8F0423PJ005SG2156 is recommended for new production due to its active product status, ROHS3 compliance, and ongoing manufacturer support. The Z8F0423PJ005SC is obsolete and subject to supply discontinuation.

Q: Are memory specifications identical between these parts?

A: Yes. Both parts feature 4KB FLASH program memory, 1KB RAM, and identical memory access specifications. Firmware compatibility is complete.

Q: Do both parts support the same operating voltage range?

A: Yes. Both parts operate within the 2.7V to 3.6V supply voltage range with identical electrical characteristics across this range.
