Substitute Part Grouping Explanation

Substitution of the Z8F012APB020SC is determined by strict equivalence across the following critical parameters:

• Processor Architecture: eZ8 core processor
• Memory Configuration: 1KB FLASH program memory, 256 bytes RAM, 16 bytes EEPROM
• Electrical Specifications: 20MHz operating speed, 2.7V ~ 3.6V supply voltage range
• Peripheral Set: Identical connectivity (IrDA, UART/USART) and integrated functions (PWM, ADC, temperature sensor, watchdog timer)
• Physical Package: 8-DIP through-hole form factor with 0.300" (7.62mm) pitch
• I/O Configuration: 6 I/O pins

The Z8F012APB020SG meets all substitution criteria as a direct equivalent, differing only in packaging format (tube vs. strip) and product status (active vs. obsolete).

Parameter Comparison

Engineering Selection Recommendations

The Z8F012APB020SG is a direct functional equivalent to the Z8F012APB020SC. Selection between these parts is determined by regulatory and supply considerations:

Z8F012APB020SG is preferred for new designs and ongoing production due to active product status and ROHS3 compliance. This part satisfies modern regulatory requirements and benefits from continued manufacturer support.

Z8F012APB020SC remains suitable for legacy system maintenance where existing inventory or design lock-in requires the original part number. However, the obsolete status indicates limited future availability.

Both parts share identical electrical performance, memory configuration, peripheral functionality, and physical packaging, ensuring direct interchangeability at the circuit level.

Frequently Asked Questions (FAQ)

Q: Can Z8F012APB020SG replace Z8F012APB020SC in existing designs?

A: Yes. Both parts are electrically and functionally identical. The substitute differs only in packaging format (tube vs. strip) and product lifecycle status. No circuit modifications are required.

Q: What is the difference between the packaging formats?

A: Z8F012APB020SC uses strip packaging; Z8F012APB020SG uses tube packaging. Both contain the same 8-DIP component with identical pin configuration and electrical characteristics. Packaging format affects handling and storage but not electrical performance.

Q: Why is Z8F012APB020SC marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production. Z8F012APB020SG, the active equivalent, is the recommended source for new component procurement.

Q: Are there compliance differences between these parts?

A: Yes. Z8F012APB020SG is ROHS3 compliant, while Z8F012APB020SC is RoHS non-compliant. For applications subject to RoHS regulations, Z8F012APB020SG is the required choice.

Q: Do these parts have identical pinouts?

A: Yes. Both use the 8-DIP (0.300", 7.62mm) package with identical pin assignments, voltage requirements (2.7V ~ 3.6V), and I/O configuration (6 pins).

Q: What memory specifications are identical between these parts?

A: Both contain 1KB FLASH program memory, 256 bytes RAM, and 16 bytes EEPROM. Operating speed is 20MHz for both parts.
