Substitute Part Grouping Explanation

Substitution eligibility for the Z8F0423PB005SC is determined by strict equivalence across the following critical parameters:

• Core processor architecture (eZ8)
• Core size (8-Bit)
• Operating frequency (5MHz)
• Program memory capacity and type (4KB FLASH)
• RAM capacity (1K x 8)
• Supply voltage range (2.7V ~ 3.6V)
• Data converter specifications (A/D 4x10b)
• I/O pin count (6)
• Physical package (8-DIP through-hole)
• Operating temperature range (0°C ~ 70°C)

The Z8F0423PB005SG qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters. The primary distinction between these parts is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The Z8F0423PB005SG is the direct functional equivalent of the Z8F0423PB005SC. Selection between these parts should be based on the following factors:

Product Status: The Z8F0423PB005SG carries active product status, ensuring ongoing manufacturer support and availability. The Z8F0423PB005SC is obsolete, limiting future procurement options.

Regulatory Compliance: The Z8F0423PB005SG meets ROHS3 compliance requirements, while the Z8F0423PB005SC is RoHS non-compliant. For applications subject to RoHS directives or customer compliance mandates, the Z8F0423PB005SG is the appropriate selection.

Packaging: The Z8F0423PB005SG is supplied in tube packaging, whereas the Z8F0423PB005SC uses standard packaging. Packaging selection depends on production volume and handling requirements.

Both parts are REACH Unaffected and classified under ECCN EAR99 with identical HTSUS codes (8542.31.0001).

Frequently Asked Questions (FAQ)

Q: Are the Z8F0423PB005SC and Z8F0423PB005SG pin-compatible?

A: Yes. Both devices use the 8-DIP (0.300", 7.62mm) through-hole package with identical pin configurations and electrical characteristics. Direct PCB substitution is possible without layout modifications.

Q: What is the primary difference between these two parts?

A: The Z8F0423PB005SG is the active production equivalent of the obsolete Z8F0423PB005SC. The substitute part offers ROHS3 compliance, active product status, and tube packaging. All electrical and mechanical specifications are identical.

Q: Can the Z8F0423PB005SG replace the Z8F0423PB005SC in existing designs?

A: Yes. Identical core processor architecture, memory configuration, operating frequency, supply voltage, and peripheral set ensure functional equivalence. No firmware or hardware modifications are required.

Q: Are there any compliance considerations when switching to the Z8F0423PB005SG?

A: The Z8F0423PB005SG meets ROHS3 compliance standards, whereas the Z8F0423PB005SC does not. If your application or market requires RoHS compliance, the Z8F0423PB005SG is the appropriate selection.

Q: What packaging options are available?

A: The Z8F0423PB005SC uses standard packaging. The Z8F0423PB005SG is supplied in tube packaging. Packaging selection should align with production volume and automated assembly requirements.

Q: Are both parts subject to the same export classifications?

A: Yes. Both parts carry identical ECCN (EAR99) and HTSUS (8542.31.0001) classifications and are REACH Unaffected.
