TL7757CLPRE3 Equivalent & Substitute Parts

Part Overview

The TL7757CLPRE3 is a supervisor integrated circuit from Texas Instruments designed for power management applications. It functions as a simple reset/power-on reset device with open drain or open collector output, monitoring a single voltage threshold at 4.55V. The device is packaged in TO-92-3 (TO-226AA) through-hole configuration.

The TL7757CLPRE3 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this component.

Substitute Part Grouping Explanation

Substitution eligibility for the TL7757CLPRE3 is determined by strict alignment with the following critical parameters:

Manufacturer: Texas Instruments (same family)
Base Product Number: TL7757
Type: Simple Reset/Power-On Reset
Number of Voltages Monitored: 1 channel
Voltage Threshold: 4.55V
Output Configuration: Open Drain or Open Collector
Reset Logic: Active Low
Reset Timeout: 5µs Maximum Propagation Delay
Package/Case: TO-226-3, TO-92-3 (TO-226AA) Formed Leads
Mounting Type: Through Hole

Substitute parts must maintain identical electrical specifications and mechanical compatibility. Variations in product status, operating temperature range, packaging format (cut tape vs. other formats), and inventory availability do not disqualify substitution when core functional parameters remain unchanged.

Engineering Selection Recommendations

Both TL7757ILPR and TL7757CLPR are valid substitutes for the obsolete TL7757CLPRE3, with selection based on application requirements and compliance considerations.

TL7757ILPR is recommended for applications requiring extended operating temperature coverage. This part maintains active product status and supports operation across -40°C to 85°C, providing broader thermal performance than the original specification. It is ROHS3 compliant and REACH unaffected.

TL7757CLPR is recommended for applications with operating temperature requirements matching the original specification (0°C to 70°C). This part maintains parametric equivalence with the TL7757CLPRE3 and carries active product status. It is ROHS3 compliant and REACH unaffected.

Both substitute parts are manufactured by Texas Instruments and share identical electrical and mechanical specifications with the main part across all critical parameters. Selection between them depends solely on whether the extended temperature range of TL7757ILPR is required for the target application.

Frequently Asked Questions (FAQ)

Q: Can TL7757ILPR and TL7757CLPR be used interchangeably with TL7757CLPRE3?

A: Yes. Both parts maintain identical voltage threshold (4.55V), output configuration (open drain or open collector), reset logic (active low), and propagation delay (5µs maximum). Package and mounting type are identical. Electrical and mechanical compatibility is confirmed.

Q: What is the primary difference between TL7757ILPR and TL7757CLPR?

A: The operating temperature range differs. TL7757ILPR operates from -40°C to 85°C, while TL7757CLPR operates from 0°C to 70°C. The TL7757CLPRE3 original specification matches TL7757CLPR at 0°C to 70°C. Select TL7757ILPR only if extended low-temperature or high-temperature operation is required.

Q: Are there packaging format differences between these parts?

A: The main part (TL7757CLPRE3) is supplied in standard packaging format. Both substitute parts (TL7757ILPR and TL7757CLPR) are supplied in cut tape (CT) format. The TO-92-3 package and through-hole mounting type remain identical across all three parts.

Q: Do all three parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected. ECCN classification is EAR99 for all parts. HTSUS code is 8542.39.0001 for all parts.

Q: Why is the TL7757CLPRE3 marked as obsolete?

A: Product status reflects Texas Instruments' lifecycle management. Active alternatives (TL7757ILPR and TL7757CLPR) are available to support continued design implementation and production requirements.
