Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Z53C8003VSC is determined by the following critical parameters:

• SCSI Type: Both main and substitute parts must function as SCSI terminators
• Number of Terminations: Must provide 8 terminations
• Supply Voltage Range: Must operate within 4.75V ~ 5.25V
• Operating Temperature Range: Must support 0°C ~ 70°C
• Mounting Type: Must be Surface Mount compatible
• Package Configuration: Must use 44-LCC (J-Lead) / 44-PLCC package
• Series Compatibility: Z53C80 series base product number

The Z53C8003VSG meets all substitution criteria, maintaining identical electrical specifications and mechanical packaging while offering improved compliance status.

Parameter Comparison

Engineering Selection Recommendations

The Z53C8003VSG is the qualified substitute for Z53C8003VSC applications. Both parts maintain identical electrical and mechanical specifications across all critical parameters including supply voltage, operating temperature range, termination count, and package configuration.

The Z53C8003VSG offers the following advantages:

• Compliance Status: ROHS3 compliant, compared to the non-compliant status of the original part
• Product Lifecycle: Last Time Buy status provides a defined procurement window, whereas the main part is obsolete
• Regulatory Alignment: Meets current environmental and regulatory requirements

Selection between these parts should be based on procurement timeline and regulatory compliance requirements for the end application.

Frequently Asked Questions (FAQ)

Q: Can Z53C8003VSG be used as a direct replacement for Z53C8003VSC?

A: Yes. Both parts share identical electrical specifications (supply voltage, operating temperature, termination count) and mechanical packaging (44-PLCC surface mount). No circuit modifications are required for substitution.

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

A: The primary differences are product lifecycle status and RoHS compliance. Z53C8003VSC is obsolete and RoHS non-compliant, while Z53C8003VSG is Last Time Buy and ROHS3 compliant. Electrical and mechanical parameters are identical.

Q: Are there any packaging differences between Z53C8003VSC and Z53C8003VSG?

A: Both parts use 44-PLCC surface mount packaging with 44-LCC (J-Lead) configuration. The main part is supplied without specified packaging, while the substitute is supplied in Tube packaging. The component footprint and pinout remain identical.

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

A: Both Z53C8003VSC and Z53C8003VSG have MSL 3 rating with a 168-hour floor life. Standard moisture control procedures during storage and handling apply to both parts.

Q: Are there any regulatory or compliance considerations for substitution?

A: The Z53C8003VSG provides ROHS3 compliance, which may be required for new designs or systems subject to environmental regulations. The original Z53C8003VSC is RoHS non-compliant and suitable only for legacy system maintenance where compliance exemptions apply.
