Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL7733BCP is determined by the following critical parameters:

• Functional Type: Single-channel supervisor with reset/power-on reset capability
• Output Configuration: Open drain or open collector output
• Voltage Monitoring: Single voltage threshold monitoring
• Reset Logic Compatibility: Active High/Active Low reset capability
• Regulatory Compliance: ROHS3 compliance and EAR99 classification

The TPS3760A012DYYR qualifies as a manufacturer-recommended substitute based on matching functional architecture (single-channel supervisor with open drain/open collector output), identical regulatory compliance (ROHS3, EAR99), and equivalent HTSUS classification. Both devices operate within the power management supervisor category and support reset/power-on reset functionality.

Parameter Comparison

Engineering Selection Recommendations

The TPS3760A012DYYR is the manufacturer-recommended substitute for the TL7733BCP. Selection of this substitute is supported by:

• Product Status: The TPS3760A012DYYR maintains Active product status, ensuring continued availability and manufacturing support, whereas the TL7733BCP is Last Time Buy.
• Regulatory Compliance: Both devices maintain ROHS3 compliance and EAR99 classification, meeting identical regulatory requirements.
• Functional Equivalence: Both devices operate as single-channel supervisors with open drain/open collector output and reset/power-on reset functionality.
• Temperature Range Extension: The TPS3760A012DYYR supports an extended operating temperature range (-40°C ~ 125°C) compared to the TL7733BCP (0°C ~ 70°C), providing greater thermal flexibility for diverse applications.

Design migration from TL7733BCP to TPS3760A012DYYR requires consideration of package transition from through-hole 8-DIP to surface-mount SOT-23-14 Thin, which may necessitate PCB layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the TPS3760A012DYYR directly replace the TL7733BCP without circuit modifications?

A: Functional substitution is supported based on matching supervisor architecture and output configuration. However, package transition from 8-DIP through-hole to SOT-23-14 surface-mount requires PCB redesign. Pin-level compatibility must be verified against specific application schematics.

Q: What are the key differences between these two supervisor ICs?

A: Primary differences include: (1) Package type and mounting method (through-hole vs. surface-mount), (2) Operating temperature range (TL7733BCP: 0°C ~ 70°C; TPS3760A012DYYR: -40°C ~ 125°C), (3) Voltage threshold specifications (TL7733BCP: 3.08V; TPS3760A012DYYR: 0.8V), and (4) Reset timeout characteristics (TL7733BCP: 270ns typical; TPS3760A012DYYR: 100µs maximum).

Q: Why is the TL7733BCP in Last Time Buy status?

A: Last Time Buy status indicates Texas Instruments has discontinued active production of this device. The TPS3760A012DYYR represents the active product line continuation for single-channel supervisor applications.

Q: Are both devices RoHS compliant?

A: Yes, both the TL7733BCP and TPS3760A012DYYR are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What inventory considerations apply to these parts?

A: The TL7733BCP has 2124 pieces available in tube packaging (Last Time Buy stock). The TPS3760A012DYYR has 5400 pieces available in tape & reel packaging (Active product). For new designs, the TPS3760A012DYYR is recommended due to active product status and higher available inventory.
