Substitute Part Grouping Explanation

Substitution of the PCF8564AU/5GC/1,01 is determined by electrical and functional equivalence across the following critical parameters:

• Interface Protocol: I2C and 2-wire serial communication compatibility
• Voltage Supply Range: 1V ~ 5.5V operating range
• Timekeeping Current Consumption: 0.6µA ~ 0.75µA @ 2V ~ 5V
• Operating Temperature Range: -40°C ~ 85°C
• Time and Date Format: HH:MM:SS (24 hr) and YY-MM-DD-dd
• Functional Features: Alarm, Leap Year, Square Wave Output, Watchdog Timer
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected
• Mounting and Package: Surface Mount Die configuration

The PCF8564AU/5GB/1,01 meets all electrical, functional, and regulatory requirements for direct substitution. The primary distinction is product status: the original part is obsolete, while the substitute is active.

Parameter Comparison

Engineering Selection Recommendations

The PCF8564AU/5GB/1,01 is the direct substitute for the obsolete PCF8564AU/5GC/1,01. Both parts are manufactured by NXP USA Inc. and share identical electrical specifications, functional capabilities, and regulatory compliance certifications. The substitute part is currently active in production, ensuring availability for new designs and field service applications. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements. Selection of the active substitute part eliminates obsolescence risk while maintaining full functional and electrical compatibility with existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Are the PCF8564AU/5GC/1,01 and PCF8564AU/5GB/1,01 electrically identical?

A: Yes. Both parts operate across the same voltage supply range (1V ~ 5.5V), consume identical timekeeping current (0.6µA ~ 0.75µA @ 2V ~ 5V), and support the same operating temperature range (-40°C ~ 85°C). All functional features, including alarm, leap year compensation, square wave output, and watchdog timer, are identical.

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

A: The primary difference is product status. The PCF8564AU/5GC/1,01 is obsolete, while the PCF8564AU/5GB/1,01 is active. The packaging designation differs (GC versus GB), but both are Surface Mount Die configurations with identical electrical and functional specifications.

Q: Can I use the PCF8564AU/5GB/1,01 as a direct replacement in existing designs?

A: Yes. The substitute part is a direct replacement. No circuit modifications, firmware changes, or design alterations are required. The I2C and 2-wire serial interface protocols, voltage requirements, and functional behavior are identical.

Q: Are both parts compliant with environmental and regulatory standards?

A: Yes. Both the PCF8564AU/5GC/1,01 and PCF8564AU/5GB/1,01 are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is 1 (Unlimited) for both parts.

Q: Why should I transition from the obsolete part to the active substitute?

A: The obsolete part faces long-term availability constraints. Transitioning to the active substitute ensures continued component supply for production and field service. The substitute provides identical functionality and performance with no design impact.
