Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL7733BIDG4 is determined by strict equivalence across the following critical parameters:

• Functional Type: Simple Reset/Power-On Reset supervisor with single voltage channel monitoring
• Voltage Threshold: 3.08V monitoring threshold
• Output Configuration: Open Drain or Open Collector output
• Reset Logic: Active High/Active Low capability
• Propagation Delay: 270ns typical reset timeout
• Package Specification: 8-SOIC form factor with identical physical dimensions (0.154", 3.90mm Width)
• Operating Temperature: -40°C to 85°C range
• Compliance Standards: ROHS3 compliance, REACH unaffected status, and MSL Level 1

The TL7733BID represents the direct functional equivalent, sharing the identical base product number (TL7733) and all critical electrical and mechanical specifications. The primary distinction is product status and packaging format.

Frequently Asked Questions (FAQ)

Q: Can the TL7733BID directly replace the TL7733BIDG4 in existing designs?

A: Yes. The TL7733BID is electrically and mechanically identical to the TL7733BIDG4. All functional parameters, including voltage threshold (3.08V), output configuration (open drain/open collector), propagation delay (270ns), operating temperature range (-40°C to 85°C), and package specification (8-SOIC) are equivalent. Direct substitution is supported without circuit modification.

Q: What is the difference between TL7733BIDG4 and TL7733BID?

A: The primary difference is product status. The TL7733BIDG4 is obsolete, while the TL7733BID is active. The TL7733BID is supplied in tube packaging, whereas the TL7733BIDG4 packaging format differs. All electrical and mechanical specifications remain identical.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the TL7733BIDG4 and TL7733BID carry identical compliance certifications: ROHS3 compliance, REACH unaffected status, MSL Level 1, and equivalent ECCN and HTSUS classifications.

Q: What does the 8-SOIC package specification mean?

A: The 8-SOIC (Small Outline Integrated Circuit) package is a surface mount form factor with 8 pins. The specification 0.154" (3.90mm width) defines the physical dimensions. Both substitute parts use this identical package, ensuring PCB footprint compatibility.

Q: Is the TL7733BID the only available substitute?

A: Based on the provided specifications, the TL7733BID is the manufacturer-recommended equivalent. Both parts share the same base product number (TL7733) and all critical functional parameters.
