Parameter Comparison

Engineering Selection Recommendations

The Z88C0120VSG is the direct functional equivalent of the Z88C0120VSC. Both components share identical electrical and mechanical specifications across all critical parameters. The Z88C0120VSG offers two significant advantages: active product status ensuring continued availability and ROHS3 compliance, whereas the Z88C0120VSC is obsolete and RoHS non-compliant. For new designs and ongoing system support, the Z88C0120VSG is the appropriate selection. The Z88C0120VSC should be reserved only for legacy system maintenance where component-level compatibility with existing assemblies is mandatory.

Frequently Asked Questions (FAQ)

Q: Can the Z88C0120VSG directly replace the Z88C0120VSC in existing designs?

A: Yes. Both components are electrically and mechanically identical across all functional parameters, including core processor, clock speed, memory configuration, I/O count, voltage supply range, and package type. Direct substitution is supported at the component level.

Q: What is the difference between the Z88C0120VSC and Z88C0120VSG?

A: The primary differences are product status and regulatory compliance. The Z88C0120VSC is obsolete and RoHS non-compliant. The Z88C0120VSG is active and ROHS3 compliant. Packaging differs: Z88C0120VSC has unspecified packaging, while Z88C0120VSG is supplied in Tube packaging.

Q: Why is the Z88C0120VSC classified as obsolete?

A: Obsolescence is a manufacturer designation indicating that the component is no longer in active production. The Z88C0120VSG remains in active production and serves as the current equivalent.

Q: Are there any pin-level compatibility concerns between these parts?

A: No. Both components use the 44-LCC (J-Lead) package with identical pin configurations and electrical characteristics.

Q: What is the significance of ROHS3 compliance for the Z88C0120VSG?

A: ROHS3 compliance indicates adherence to the Restriction of Hazardous Substances Directive, restricting the use of specific hazardous materials. This is relevant for applications subject to environmental and regulatory requirements in the European Union and other jurisdictions with equivalent standards.
