Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TL7733BCDG4 is determined by the following critical parameters:

• Voltage Threshold: 3.08V (must match exactly for circuit operation)
• Number of Channels: 1 (single-channel monitoring requirement)
• Output Type: Open Drain or Open Collector (functional interface requirement)
• Reset Logic: Active High/Active Low (signal polarity requirement)
• Propagation Delay: 270ns Typical (timing specification)
• Package Type: 8-SOIC form factor (PCB layout compatibility)
• Operating Temperature: 0°C to 70°C (environmental specification)
• Compliance Standards: ROHS3, REACH Unaffected (regulatory requirement)

The TL7733BCD meets all substitution criteria and is classified as a direct equivalent. This part shares identical electrical specifications, functional characteristics, and package configuration with the obsolete TL7733BCDG4.

Parameter Comparison

Engineering Selection Recommendations

The TL7733BCD is the primary substitute for the obsolete TL7733BCDG4. This part maintains Active product status with Texas Instruments, ensuring long-term availability and continued manufacturing support. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

The TL7733BCD is available in Tube packaging with 1107 units in current inventory, compared to the TL7733BCDG4 which is no longer in active production. For new designs or production continuity, the TL7733BCD is the recommended selection based on product status and compliance certification alignment.

Frequently Asked Questions (FAQ)

Q: Can the TL7733BCD directly replace the TL7733BCDG4 in existing designs?

A: Yes. Both parts share identical electrical specifications, including voltage threshold (3.08V), output configuration (open drain/open collector), reset logic (active high/active low), propagation delay (270ns typical), and package type (8-SOIC). No circuit modifications are required.

Q: What is the difference between the TL7733BCDG4 and TL7733BCD part numbers?

A: The TL7733BCDG4 is an obsolete variant. The TL7733BCD is the active production equivalent with identical functional and electrical characteristics. The suffix difference reflects manufacturing date code or packaging variation, but electrical performance remains equivalent.

Q: Are there any packaging differences between these parts?

A: Both parts use the 8-SOIC (0.154", 3.90mm Width) surface mount package. The TL7733BCD is supplied in Tube packaging, while the TL7733BCDG4 packaging specification was not provided. PCB layout and footprint compatibility is maintained.

Q: What compliance certifications apply to the TL7733BCD?

A: The TL7733BCD is ROHS3 compliant and REACH unaffected. Moisture sensitivity level is rated at MSL 1 (unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Is the TL7733BCD suitable for the same operating temperature range?

A: Yes. Both parts operate across the 0°C to 70°C (TA) temperature range, maintaining identical thermal specifications for industrial and commercial applications.
