Substitute Part Grouping Explanation

Substitution of the Z8F082APJ020SC is determined by strict equivalence across the following critical parameters:

• Core Architecture: eZ8 processor with identical 8-bit core size
• Memory Configuration: 8KB FLASH program memory and 1K x 8 RAM
• Clock Speed: 20MHz operation
• I/O Count: 23 I/O pins
• Supply Voltage: 2.7V to 3.6V operating range
• Analog Capability: 8-channel 10-bit A/D converter
• Package Form Factor: 28-DIP through-hole mounting
• Peripheral Set: IrDA, UART/USART, PWM, temperature sensor, watchdog timer, brown-out detect/reset, LED driver, LVD, and POR

The substitute part Z8F082APJ020SG2156 maintains identical electrical and functional specifications across all parameters listed above, with the primary distinction being packaging format (Tube versus standard packaging) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The Z8F082APJ020SG2156 is a direct functional equivalent to the Z8F082APJ020SC. Selection between these parts should be based on the following factors:

Product Status: The Z8F082APJ020SG2156 maintains Active product status, ensuring continued availability and manufacturer support. The Z8F082APJ020SC is Obsolete, making the substitute the preferred choice for new designs and long-term production requirements.

Regulatory Compliance: The Z8F082APJ020SG2156 is ROHS3 Compliant, meeting current environmental and hazardous substance restrictions. The Z8F082APJ020SC is RoHS non-compliant and may not satisfy procurement requirements for regulated applications.

Packaging Format: The Z8F082APJ020SG2156 is supplied in Tube packaging, which may differ from the original part's packaging format. Verify that tube packaging is compatible with your assembly and handling processes.

Electrical and Functional Equivalence: Both parts are electrically and functionally identical across all specified parameters, including memory configuration, I/O count, supply voltage range, and peripheral set. No circuit modifications are required for substitution.

Frequently Asked Questions (FAQ)

Q: Are the Z8F082APJ020SC and Z8F082APJ020SG2156 pin-compatible?

A: Yes. Both devices use the 28-DIP (0.600", 15.24mm) package with identical pin assignments and electrical characteristics. Direct socket substitution is possible without PCB modifications.

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

A: The primary differences are product status (Obsolete versus Active), RoHS compliance level (non-compliant versus ROHS3 Compliant), and packaging format (standard versus Tube). All electrical specifications and functional capabilities are identical.

Q: Can I use the Z8F082APJ020SG2156 as a drop-in replacement in existing designs?

A: Yes. The Z8F082APJ020SG2156 is electrically and functionally equivalent. No design changes, firmware modifications, or circuit alterations are required. Verify that tube packaging is compatible with your assembly process.

Q: Does the RoHS3 compliance of the Z8F082APJ020SG2156 affect circuit performance?

A: No. RoHS3 compliance indicates adherence to hazardous substance restrictions and does not alter electrical performance, timing, or functional behavior. The device operates identically to the non-compliant version.

Q: Are there any memory or speed differences between these parts?

A: No. Both parts feature 8KB FLASH program memory, 1KB RAM, and 20MHz clock speed. Memory organization, access timing, and instruction execution are identical.

Q: What is the significance of the Tube packaging for the Z8F082APJ020SG2156?

A: Tube packaging affects handling, storage, and automated assembly compatibility. Verify that your pick-and-place equipment and tape-and-reel feeders support tube-packaged components, or plan for manual handling during assembly.

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

A: Yes. Both the Z8F082APJ020SC and Z8F082APJ020SG2156 operate across 0°C to 70°C (TA). No thermal performance differences exist between the two parts.

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

A: Yes, provided your assembly process accommodates both packaging formats. Electrically and functionally, the parts are interchangeable. Document the substitution in your bill of materials and design records.
