Frequently Asked Questions (FAQ)

Q: Can the Z84C1516FSG be used as a direct replacement for the Z84C1516FSC?

A: Yes. Both parts are electrically and mechanically identical, with matching core processor, clock speed, voltage specifications, operating temperature range, and 100-QFP package configuration. The Z84C1516FSG is a direct substitute.

Q: What is the difference between the Z84C1516FSC and Z84C1516FSG?

A: The primary differences are product status and regulatory compliance. The Z84C1516FSC is obsolete and RoHS non-compliant, while the Z84C1516FSG is active and ROHS3 compliant. Functionally and physically, they are identical.

Q: Are there any package or pinout differences between these parts?

A: No. Both components use the 100-QFP (14x20) package with identical pinout and physical dimensions. They are pin-for-pin compatible.

Q: What does MSL 3 (168 Hours) mean for handling and storage?

A: Moisture Sensitivity Level 3 indicates the component requires controlled storage conditions. The part can be exposed to ambient conditions for up to 168 hours before soldering. Extended storage requires dry-pack conditions with desiccant.

Q: Is the Z84C1516FSG suitable for new product designs?

A: Yes. The Z84C1516FSG is actively manufactured and meets current RoHS3 compliance standards, making it appropriate for new designs utilizing Z80 microprocessor architecture.
