Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL7702BCDRE4 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: 2.53V monitoring threshold
• Output Type: Open Drain or Open Collector configuration
• Reset Logic: Active High/Active Low capability
• Propagation Delay: 270ns typical reset timeout
• Package Specification: 8-SOIC form factor with identical 0.154" (3.90mm) width
• Operating Temperature: 0°C to 70°C range
• Compliance Standards: ROHS3 compliance and MSL Level 1 rating

The TL7702BCDR meets all these criteria and serves as the direct equivalent for the obsolete TL7702BCDRE4.

Frequently Asked Questions (FAQ)

Q: Can the TL7702BCDR directly replace the TL7702BCDRE4 in existing designs?

A: Yes. The TL7702BCDR is electrically and mechanically identical to the TL7702BCDRE4. Both parts feature the same 2.53V voltage threshold, open drain/open collector output, active high/active low reset logic, 270ns propagation delay, and 8-SOIC package dimensions. No circuit modifications are required.

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

A: The TL7702BCDRE4 is classified as obsolete, while the TL7702BCDR maintains active product status. The packaging designation differs (BCDRE4 versus BCDR), but the electrical and functional specifications are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, carry MSL Level 1 rating, and maintain REACH Unaffected status. ECCN classification is identical (EAR99) for both parts.

Q: What package format is used for the TL7702BCDR?

A: The TL7702BCDR is supplied in Cut Tape (CT) and Digi-Reel® packaging options. The physical package remains 8-SOIC with 0.154" (3.90mm) width, maintaining compatibility with existing PCB layouts and assembly processes.

Q: Is the operating temperature range the same for both parts?

A: Yes. Both the TL7702BCDRE4 and TL7702BCDR operate across the 0°C to 70°C temperature range (TA).
