Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL7757ILPRE3 is determined by strict equivalence across the following critical parameters:

• Voltage Monitoring Capability: Single channel at 4.55V threshold
• Output Type: Open drain or open collector configuration
• Reset Logic Level: Active low operation
• Propagation Delay: 5µs maximum
• Temperature Range: -40°C to 85°C operational window
• Package Compatibility: TO-92-3 through-hole form factor
• Regulatory Compliance: ROHS3 and REACH requirements

The TL7757ILPR qualifies as a parametric equivalent based on identical electrical specifications and package configuration. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The TL7757ILPR is a direct functional equivalent to the TL7757ILPRE3 for applications requiring single-channel voltage supervision with active-low reset output. Both parts maintain identical electrical specifications, operating parameters, and regulatory compliance certifications. The TL7757ILPR carries active product status from Texas Instruments, providing assurance of continued availability and manufacturing support. Selection of the TL7757ILPR is appropriate for new designs and ongoing production where the obsolete TL7757ILPRE3 requires replacement. Packaging format differs between tube and cut tape configurations; procurement requirements should align with assembly process specifications.

Frequently Asked Questions (FAQ)

Q: Can the TL7757ILPR directly replace the TL7757ILPRE3 in existing designs?

A: Yes. Both parts share identical electrical specifications, including voltage threshold, output configuration, reset logic, propagation delay, and operating temperature range. The TO-92-3 package pinout and form factor are equivalent, enabling direct substitution in through-hole applications.

Q: What is the significance of the product status difference?

A: The TL7757ILPRE3 is classified as obsolete, indicating Texas Instruments has discontinued active manufacturing and support. The TL7757ILPR maintains active status, ensuring continued availability, manufacturing consistency, and technical support from the manufacturer.

Q: Are there differences in regulatory compliance between these parts?

A: No. Both the TL7757ILPRE3 and TL7757ILPR maintain ROHS3 compliance and REACH unaffected status. Regulatory requirements are satisfied by either part.

Q: What is the difference between tube and cut tape packaging?

A: Tube packaging (TR) and cut tape packaging (CT) represent different distribution formats. Tube packaging typically suits lower-volume or manual assembly processes, while cut tape is standard for automated pick-and-place assembly. Selection depends on production methodology and assembly equipment compatibility.

Q: Are the electrical characteristics identical between these parts?

A: Yes. The voltage threshold (4.55V), output type (open drain/open collector), reset logic (active low), propagation delay (5µs maximum), and operating temperature range (-40°C to 85°C) are identical across both parts.
