Substitute Part Grouping Explanation

Substitution eligibility for the Z8F021APB020EC is determined by strict equivalence across the following critical parameters:

• Manufacturer & Series: Must be Zilog eZ8 Encore!® XP® series
• Core Architecture: 8-bit eZ8 processor
• Memory Configuration: 2KB FLASH, 512 bytes RAM, 64 bytes EEPROM
• Operating Specifications: 20MHz speed, 2.7V–3.6V supply voltage
• Peripheral Set: Identical peripheral integration (PWM, WDT, brown-out detection, LVD, POR, LED, IrDA, UART/USART)
• I/O Count: 6 I/O pins
• Package: 8-DIP through-hole form factor
• Temperature Range: -40°C to 105°C

The Z8F021APB020EG qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters. The primary distinction is packaging format and product status.

Engineering Selection Recommendations

The Z8F021APB020EG is a direct functional equivalent to the Z8F021APB020EC. Selection between these parts should be based on the following factors:

Product Status: The Z8F021APB020EC is obsolete, while the Z8F021APB020EG maintains active product status. For new designs or long-term system support, the Z8F021APB020EG is the appropriate choice.

Compliance & Certification: The Z8F021APB020EG is ROHS3 compliant, whereas the Z8F021APB020EC is RoHS non-compliant. Applications subject to RoHS regulations require the Z8F021APB020EG.

Packaging & Availability: The Z8F021APB020EG is supplied in tube packaging format. Both parts share identical electrical specifications and 8-DIP through-hole package geometry, ensuring direct PCB compatibility.

Supply Chain Continuity: With 635 units in stock, the Z8F021APB020EG provides superior availability compared to the obsolete Z8F021APB020EC.

Frequently Asked Questions (FAQ)

Q: Can Z8F021APB020EG replace Z8F021APB020EC in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The Z8F021APB020EG provides a direct drop-in replacement with no circuit modifications required. Pin configuration, memory organization, peripheral functionality, and electrical operating parameters are identical.

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

A: The primary differences are product status (obsolete vs. active), RoHS compliance classification, and packaging format (standard vs. tube). All functional and electrical specifications are equivalent.

Q: Are there any compatibility concerns with the 8-DIP package?

A: No. Both parts use the identical 8-DIP (0.300", 7.62mm) through-hole package. PCB footprints, pin assignments, and mounting procedures are identical.

Q: Why is the Z8F021APB020EC marked as obsolete?

A: Zilog has transitioned this product line to active status under the Z8F021APB020EG designation. The Z8F021APB020EG represents the current production equivalent with improved compliance status.

Q: Does the tube packaging of Z8F021APB020EG affect functionality?

A: No. Packaging format is a supply and handling consideration only. Tube packaging does not alter electrical performance, specifications, or circuit behavior.

Q: What are the key parameters that determine substitutability?

A: Core processor architecture (eZ8), memory configuration (2KB FLASH/512B RAM/64B EEPROM), operating speed (20MHz), supply voltage range (2.7V–3.6V), peripheral set, I/O count (6), and package type (8-DIP through-hole) must all match exactly for substitution eligibility.
