Substitute Part Grouping Explanation

Substitution of the Z8F081APH020SC is determined by strict equivalence across the following critical parameters:

• Core Architecture: eZ8 processor family with identical 8-bit core size
• Memory Configuration: 8KB FLASH program memory and 1KB RAM capacity
• Clock Speed: 20MHz maximum operating frequency
• I/O Count: 17 input/output pins
• Connectivity & Peripherals: IrDA, UART/USART, PWM, watchdog timer, brown-out detection, and low-voltage detection
• Electrical Specifications: 2.7V to 3.6V supply voltage range and 0°C to 70°C operating temperature
• Physical Package: 20-DIP through-hole form factor with 0.300" (7.62mm) pitch

The substitute part Z8F081APH020SG2156 maintains full electrical and functional equivalence to the main part while differing in packaging format (tube vs. standard) and product status (active vs. obsolete).

Parameter Comparison

Engineering Selection Recommendations

The Z8F081APH020SG2156 is the direct functional equivalent for the obsolete Z8F081APH020SC. Selection between these parts should be based on the following criteria:

For New Designs and Long-Term Support: Z8F081APH020SG2156 is the appropriate choice. This part carries active product status from Zilog and meets ROHS3 compliance requirements, ensuring availability and regulatory alignment for current manufacturing standards.

For Legacy System Maintenance: Z8F081APH020SC remains suitable for repair and replacement in existing systems where the original part specification is required. However, availability is limited due to obsolete status.

Compliance Considerations: The Z8F081APH020SG2156 provides ROHS3 compliance and REACH unaffected status, meeting modern environmental and regulatory requirements. The Z8F081APH020SC is RoHS non-compliant and should not be specified for new applications subject to RoHS directives.

Packaging and Supply Chain: The Z8F081APH020SG2156 is supplied in tube packaging with higher inventory availability (1138 pcs vs. 977 pcs), supporting production volume requirements more effectively.

Frequently Asked Questions (FAQ)

Q: Can Z8F081APH020SG2156 be used as a direct replacement for Z8F081APH020SC?

A: Yes. Both parts are electrically and functionally identical across all critical parameters: core processor, memory configuration, clock speed, I/O count, voltage range, temperature range, and peripheral set. The parts are pin-compatible and require no circuit modifications.

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: Why should I choose Z8F081APH020SG2156 for new designs?

A: The Z8F081APH020SG2156 has active product status, ensuring long-term availability and supply chain stability. It meets ROHS3 compliance requirements, which is mandatory for many markets and applications. The Z8F081APH020SC is obsolete and should not be specified for new development.

Q: Are there any pinout differences between these parts?

A: No. Both parts use the identical 20-DIP (0.300", 7.62mm) package with 17 I/O pins. Pinout and footprint are fully compatible.

Q: What is the significance of the RoHS compliance difference?

A: ROHS3 compliance indicates the Z8F081APH020SG2156 meets current European Union Restriction of Hazardous Substances directives. The Z8F081APH020SC, being RoHS non-compliant, may face restrictions in certain markets and applications. For regulatory compliance, the Z8F081APH020SG2156 is the appropriate selection.

Q: Can I mix these parts in the same production batch?

A: Yes. Since the parts are electrically and functionally identical, they can be used interchangeably in the same circuit design and production environment. However, for traceability and compliance documentation, it is recommended to maintain consistent part selection within a single product revision.

Q: What is the inventory status for these parts?

A: Z8F081APH020SC has 977 pcs in stock (obsolete status). Z8F081APH020SG2156 has 1138 pcs in stock (active status). The active part offers better long-term availability assurance.
