Substitute Part Grouping Explanation

Substitution eligibility for the Z8018233FSC is determined by the following critical parameters:

• Core Processor: Z80180 (identical architecture required)
• Number of Cores/Bus Width: 1 Core, 8-Bit (functional equivalence)
• Speed: 33MHz (operational frequency match)
• Voltage - I/O: 5.0V (electrical compatibility)
• Operating Temperature: 0°C ~ 70°C (thermal envelope)
• Package / Case: 100-QFP (physical and electrical footprint)
• Mounting Type: Surface Mount (PCB assembly compatibility)
• Additional Interfaces: ASCI, CSIO, SCC, UART (functional interface set)

The Z8018233FSG qualifies as a direct substitute, meeting all electrical, mechanical, and functional parameters while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The Z8018233FSG is the direct substitute for Z8018233FSC. Both parts share identical electrical specifications, core processor architecture, operating frequency, voltage requirements, and thermal characteristics. The Z8018233FSG offers two significant advantages:

1. Active Product Status: Z8018233FSG maintains active manufacturing status, ensuring continued availability and supply chain reliability compared to the obsolete Z8018233FSC.

2. Regulatory Compliance: Z8018233FSG achieves ROHS3 compliance, whereas Z8018233FSC is RoHS non-compliant. For applications subject to environmental regulations or procurement standards requiring RoHS compliance, Z8018233FSG is the appropriate selection.

Both parts maintain identical REACH status (REACH Unaffected) and export classification (ECCN 3A991A2).

Frequently Asked Questions (FAQ)

Q: Can Z8018233FSG directly replace Z8018233FSC in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The Z8018233FSG operates at the same 33MHz frequency, uses identical 5.0V I/O voltage, and maintains the same 100-QFP surface mount package. All interface functions (ASCI, CSIO, SCC, UART) are preserved.

Q: What is the difference between Z8018233FSC and Z8018233FSG?

A: The primary differences are product status and RoHS compliance. Z8018233FSC is obsolete and RoHS non-compliant, while Z8018233FSG is active and ROHS3 compliant. Electrical and functional specifications are identical.

Q: Are there packaging differences between these parts?

A: Both parts use 100-QFP surface mount packaging. Z8018233FSC is supplied without specified packaging, while Z8018233FSG is supplied in Tray packaging. The electrical footprint and pin configuration are identical.

Q: What is the moisture sensitivity level for these parts?

A: Both Z8018233FSC and Z8018233FSG have MSL 3 rating with a 168-hour floor life. Standard moisture control procedures apply during storage and handling.

Q: Are these parts suitable for new designs?

A: Z8018233FSG is suitable for new designs as an active product. Z8018233FSC, being obsolete, is not recommended for new designs. For legacy system maintenance or repair, Z8018233FSG provides the appropriate substitute.
