Z8F0223PB005SC Equivalent & Substitute Parts

Part Overview

The Z8F0223PB005SC is an eZ8 Encore!® XP® 8-bit microcontroller manufactured by Zilog, featuring 2KB FLASH program memory, 512 bytes of RAM, and integrated peripherals including UART/USART connectivity, PWM, watchdog timer, and brown-out detection. This device operates at 5MHz with a supply voltage range of 2.7V to 3.6V and is housed in an 8-DIP through-hole package.

The Z8F0223PB005SC carries an obsolete product status. Identifying equivalent substitute parts is necessary for design continuity, system maintenance, and component procurement when original inventory becomes unavailable or depleted.

Substitute Part Grouping Explanation

Substitution eligibility for the Z8F0223PB005SC is determined by strict equivalence across the following critical parameters:

Core Processor Architecture: eZ8 processor family
Memory Configuration: 2KB FLASH program memory and 512 bytes RAM
Electrical Specifications: 5MHz operating speed, 2.7V to 3.6V supply voltage range
Peripheral Feature Set: Identical connectivity (IrDA, UART/USART) and integrated functions (PWM, WDT, brown-out detection)
Physical Package: 8-DIP through-hole form factor with 0.300" (7.62mm) pitch
I/O Count: 6 I/O pins
Data Conversion: 4-channel 10-bit analog-to-digital converter

The Z8F0223PB005SG meets all substitution criteria as a direct equivalent, differing only in packaging format (tube vs. standard) and product lifecycle status (active vs. obsolete).

Engineering Selection Recommendations

The Z8F0223PB005SG is a direct functional equivalent to the Z8F0223PB005SC. Selection between these parts should be based on the following factors:

Product Lifecycle: The Z8F0223PB005SC is obsolete, while the Z8F0223PB005SG maintains active product status. For new designs or long-term production requirements, the active part is the appropriate choice.

Regulatory Compliance: The Z8F0223PB005SG is ROHS3 compliant, whereas the Z8F0223PB005SC is RoHS non-compliant. Applications subject to RoHS directives or customer compliance requirements must use the Z8F0223PB005SG.

Packaging and Handling: Both parts are supplied in different packaging formats (standard vs. tube). Tube packaging may affect handling procedures and inventory management but does not alter electrical or functional characteristics.

Inventory Availability: The Z8F0223PB005SG has higher current inventory (1110 units) compared to the Z8F0223PB005SC (719 units), supporting procurement reliability.

Frequently Asked Questions (FAQ)

Q: Can the Z8F0223PB005SG replace the Z8F0223PB005SC in existing designs?

A: Yes. The Z8F0223PB005SG is electrically and functionally identical to the Z8F0223PB005SC. All electrical parameters, memory configuration, peripheral features, and pin assignments 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 format (standard vs. tube). Electrical and functional specifications are identical.

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

A: No. Both parts use the identical 8-DIP through-hole package with 0.300" (7.62mm) pitch. PCB footprints, socket compatibility, and mechanical mounting are fully interchangeable.

Q: Why should I choose the Z8F0223PB005SG over the Z8F0223PB005SC?

A: The Z8F0223PB005SG is recommended for new designs and ongoing production due to its active product status and ROHS3 compliance. The Z8F0223PB005SC, being obsolete, presents long-term supply risk and does not meet current regulatory requirements.

Q: Does packaging format affect electrical performance?

A: No. Tube packaging is a logistics and handling format only. It does not alter electrical characteristics, performance specifications, or functional behavior of the microcontroller.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the Z8F0223PB005SC and Z8F0223PB005SG operate across the identical temperature range of 0°C to 70°C (TA).
