• Voltage Supply Range: 4.5V ~ 5.5V
• Current Consumption: 10 mA
• Operating Temperature Range: 0°C ~ 70°C
• Package Type: 28-PLCC (11.51x11.51)
• Mounting Type: Surface Mount
• Base Product Number: 82C54 series

The CS82C54-12Z qualifies as a parametric equivalent substitute, maintaining identical electrical specifications and mechanical compatibility while offering improved RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The CS82C54-12Z serves as the direct parametric equivalent for the CS82C54-12. Both parts maintain identical electrical and mechanical specifications, ensuring functional interchangeability in circuit applications. The primary distinction lies in RoHS compliance status: the CS82C54-12Z achieves ROHS3 compliance, whereas the original CS82C54-12 is RoHS non-compliant. Both parts retain obsolete product status and identical REACH and ECCN classifications. Selection between these parts should be based on regulatory requirements and compliance mandates applicable to the end application.

Frequently Asked Questions (FAQ)
