Key Parameters

Substitute Part Grouping Explanation

The PCF8576CT/1,518 qualifies as a direct substitute based on the following alignment criteria:

Common Electrical Parameters:

• Identical manufacturer (NXP USA Inc.)
• Identical interface protocol (I2C)
• Identical package type (56-BSOP)
• Identical mounting technology (Surface Mount)
• Identical operating temperature range (-40°C ~ 85°C)
• Identical base product number (PCF8576)
• Identical compliance certifications (ROHS3, REACH Unaffected, EAR99)

Functional Compatibility: The substitute part supports LCD display configurations including 7-segment + DP, 14-segment + DP + AP, and Dot Matrix formats, with character capacity of 10, 20, or 160 elements, maintaining compatibility with the original part's display-driving capability.

Parameter Comparison

Engineering Selection Recommendations

The PCF8576CT/1,518 is the designated substitute for the obsolete PCF8576T/1,112. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and production transitions.

The substitute part operates within a reduced voltage supply range (2V ~ 6V versus 2V ~ 9V) and draws lower supply current (120 µA versus 180 µA). Applications requiring operation above 6V supply voltage or dependent on the original part's higher voltage tolerance must evaluate circuit redesign requirements.

The substitute part carries Last Time Buy status, indicating limited future availability. Procurement planning should account for this product lifecycle stage when establishing component inventory strategies.

Frequently Asked Questions (FAQ)

Q: Can the PCF8576CT/1,518 directly replace the PCF8576T/1,112 in existing designs?

A: Direct replacement is possible for applications operating within the 2V to 6V supply voltage range. Designs requiring supply voltages between 6V and 9V require circuit modification or alternative component selection.

Q: What is the significance of the different Moisture Sensitivity Level (MSL) ratings?

A: The original part (MSL 1) has unlimited shelf life under standard storage conditions. The substitute part (MSL 3) requires storage at controlled humidity levels for up to 168 hours before soldering. Procurement and storage procedures must account for this difference.

Q: Are the package dimensions identical between the two parts?

A: Both parts use the 56-BSOP package with identical dimensions (0.435", 11.05mm Width). PCB layouts and mechanical assembly procedures require no modification.

Q: What display configurations does the substitute part support?

A: The PCF8576CT/1,518 supports 7-segment + DP, 14-segment + DP + AP, and Dot Matrix configurations with character capacity of 10, 20, or 160 elements, maintaining functional compatibility with the original part's display-driving capability.

Q: How does the lower supply current of the substitute part affect circuit design?

A: The substitute part's 120 µA supply current (versus 180 µA for the original) represents a 33% reduction in power consumption. This improvement does not require circuit modification and may reduce overall system power requirements.
