TL7757CLPE3 Equivalent & Substitute Parts

Part Overview

The TL7757CLPE3 is a supervisor integrated circuit designed for power management applications, specifically functioning as a simple reset/power-on reset device. This component monitors a single voltage channel and provides active-low reset output through an open-drain or open-collector configuration. The TL7757CLPE3 carries an obsolete product status, making identification of equivalent and substitute parts essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the TL7757CLPE3 is determined by strict parametric equivalence across the following critical criteria:

Mandatory Matching Parameters:

Voltage threshold: 4.55V
Number of voltages monitored: 1 channel
Output type: Open Drain or Open Collector
Reset logic: Active Low
Reset timeout: 5µs Maximum Propagation Delay
Operating temperature range: 0°C ~ 70°C (TA)
Package/Case: TO-92-3 (TO-226AA)
Mounting type: Through Hole

The TL7757CLP meets all parametric requirements for direct substitution. Both parts share identical electrical specifications, functional characteristics, and physical packaging. The primary distinction between these parts is product status: TL7757CLPE3 is obsolete, while TL7757CLP maintains active product status with significantly higher inventory availability.

Engineering Selection Recommendations

For new designs and component procurement, TL7757CLP is the appropriate selection. This part maintains active product status from Texas Instruments and demonstrates substantially higher inventory availability (130100 units versus 2148 units). Both parts carry identical ROHS3 compliance and REACH unaffected certifications, ensuring regulatory equivalence.

For legacy system maintenance where TL7757CLPE3 components require replacement, TL7757CLP provides direct functional and physical compatibility without circuit redesign or board-level modifications. The parametric equivalence across all electrical and mechanical specifications ensures seamless integration into existing applications.

Frequently Asked Questions (FAQ)

Q: Can TL7757CLP directly replace TL7757CLPE3 in existing circuits?

A: Yes. Both parts are parametrically equivalent across all critical specifications including voltage threshold (4.55V), output configuration (open drain/open collector), reset logic (active low), propagation delay (5µs maximum), operating temperature range (0°C ~ 70°C), and package type (TO-92-3). No circuit modifications are required.

Q: What is the primary difference between TL7757CLPE3 and TL7757CLP?

A: Product status and inventory availability. TL7757CLPE3 is obsolete with limited stock (2148 units), while TL7757CLP maintains active status with substantially higher availability (130100 units). Electrical and mechanical specifications are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both TL7757CLPE3 and TL7757CLP are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Does the package type differ between these parts?

A: No. Both parts use identical TO-92-3 (TO-226AA) through-hole packaging, ensuring mechanical compatibility with existing PCB layouts and assembly processes.

Q: What voltage threshold do these supervisor ICs monitor?

A: Both parts monitor a single voltage channel with a threshold of 4.55V, providing reset signaling when supply voltage deviates from specified operating conditions.
