Substitute Part Grouping Explanation

Substitution eligibility for the Z8F082APJ020EC is determined by strict equivalence across the following critical parameters:

• Core processor architecture (eZ8)
• Core size (8-Bit)
• Operating frequency (20MHz)
• Program memory capacity and type (8KB FLASH)
• RAM capacity (1K x 8)
• Supply voltage range (2.7V ~ 3.6V)
• I/O count (23 pins)
• Peripheral feature set (IrDA, UART/USART, PWM, temperature sensor, watchdog timer, brown-out detection, LVD, POR, LED driver)
• Data converter specification (A/D 8x10b)
• Package form factor (28-DIP)
• Operating temperature range (-40°C ~ 105°C)

The Z8F082APJ020EG2156 meets all substitution criteria as a direct functional equivalent with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The Z8F082APJ020EG2156 is the direct substitute for the Z8F082APJ020EC. Both parts share identical electrical specifications, memory configuration, peripheral feature set, and package form factor. The primary distinction is product lifecycle status: the original part is obsolete while the substitute is active in production.

The Z8F082APJ020EG2156 provides additional compliance advantage through ROHS3 certification, whereas the original part is RoHS non-compliant. This compliance improvement supports regulatory requirements for new designs and long-term system support. Both parts maintain equivalent functionality for existing applications requiring the eZ8 Encore!® XP® architecture with 8KB FLASH and 20MHz operation.

Frequently Asked Questions (FAQ)

Q: Are the Z8F082APJ020EC and Z8F082APJ020EG2156 pin-compatible?

A: Yes. Both devices use the 28-DIP package with identical pinout, voltage specifications (2.7V ~ 3.6V), and I/O configuration (23 pins). Direct socket substitution is supported.

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

A: The parts are functionally equivalent with identical core specifications. The Z8F082APJ020EG2156 is the active production variant with ROHS3 compliance, while the Z8F082APJ020EC is obsolete and RoHS non-compliant.

Q: Can I use the Z8F082APJ020EG2156 in place of the Z8F082APJ020EC in existing designs?

A: Yes. The substitute part maintains full electrical and mechanical compatibility. No design modifications are required for direct replacement.

Q: Are there any firmware or software compatibility considerations?

A: No. Both parts use the identical eZ8 core processor and instruction set. Existing firmware requires no modification.

Q: What is the packaging difference between these parts?

A: The original part packaging is unspecified. The substitute is supplied in Tube packaging. Both use the 28-DIP form factor with identical mechanical dimensions (0.600", 15.24mm).
