Substitute Part Grouping Explanation

Substitution eligibility for the Z8F0423PJ005EC is determined by strict equivalence across the following critical parameters:

  • Core processor architecture (eZ8)
  • Memory configuration (4KB FLASH, 1KB RAM)
  • I/O pin count (22)
  • Voltage supply range (2.7V ~ 3.6V)
  • Operating temperature range (-40°C ~ 105°C)
  • Package type and pin configuration (28-DIP)
  • Connectivity interfaces (IrDA, UART/USART)
  • Peripheral feature set (PWM, WDT, brown-out detection, POR, LED)

The Z8F0423PJ005EG2156 meets all substitution criteria as a direct functional equivalent within the Encore® XP® series, with identical electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can Z8F0423PJ005EG2156 be used as a direct replacement for Z8F0423PJ005EC?

A: Yes. Both parts are functionally identical across all electrical and mechanical parameters. Pin configuration, memory organization, I/O count, voltage supply range, operating temperature, and peripheral features are equivalent. Direct socket substitution is supported.

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

A: The primary differences are product status and compliance certification. The Z8F0423PJ005EC is obsolete, while Z8F0423PJ005EG2156 is in active production. The substitute carries ROHS3 compliance; the original does not. Packaging format differs (tube vs. unspecified).

Q: Are there any compatibility concerns with the 28-DIP package?

A: No. Both parts use identical 28-DIP (0.600", 15.24mm) through-hole packaging. PCB footprints, pin assignments, and mechanical dimensions are equivalent.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and manufacturing processes, not electrical characteristics. Both parts deliver identical functional performance within specified operating parameters.

Q: What is the supply status for each part?

A: Z8F0423PJ005EC is obsolete with limited inventory availability. Z8F0423PJ005EG2156 is in active production with current stock availability, making it the recommended selection for new designs and ongoing system support.
