TL7757IPKG3 Equivalent & Substitute Parts

Part Overview

The TL7757IPKG3 is a single-channel power supply supervisor IC manufactured by Texas Instruments, designed for power-on reset and simple reset applications. This component monitors a single voltage threshold and provides an active-low reset output via open drain or open collector configuration. The TL7757IPKG3 is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system support and new design implementations. The TL7757IPK serves as the primary parametric equivalent, offering identical electrical specifications with active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TL7757IPKG3 is determined by strict equivalence across the following critical parameters:

• Single voltage monitoring channel
• 4.55V threshold voltage
• Open drain or open collector output configuration
• Active-low reset logic
• 5µs maximum propagation delay
• SOT-89-3 package footprint
• Surface mount technology
• Operating temperature range of -40°C to 85°C
• ROHS3 compliance and REACH unaffected status

The TL7757IPK meets all these criteria and is classified as a parametric equivalent. The primary distinction between the main part and its substitute is packaging format: the TL7757IPKG3 is supplied in Tape & Reel (TR) format, while the TL7757IPK is available in Cut Tape (CT) and Digi-Reel® formats. Both parts share identical electrical characteristics, thermal specifications, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The TL7757IPK is the direct parametric equivalent for the obsolete TL7757IPKG3. Both parts are manufactured by Texas Instruments and maintain identical electrical specifications, thermal performance, and regulatory compliance. The TL7757IPK carries active product status, ensuring continued availability and manufacturing support.

Selection between these parts depends on procurement and assembly requirements. The TL7757IPKG3 in Tape & Reel format is suitable for high-volume automated assembly processes, while the TL7757IPK in Cut Tape and Digi-Reel® formats accommodates lower-volume production runs and manual assembly workflows. Both formats deliver the same component functionality and performance characteristics.

For new designs or system redesigns, the TL7757IPK is the recommended choice due to its active product status and assured long-term availability. Existing designs using the TL7757IPKG3 can transition to the TL7757IPK without circuit modification, as all electrical and mechanical parameters remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the TL7757IPK directly replace the TL7757IPKG3 in existing designs?

A: Yes. The TL7757IPK is a parametric equivalent with identical electrical specifications, threshold voltage, output configuration, and thermal characteristics. No circuit modifications are required for substitution.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging is optimized for high-volume automated pick-and-place assembly, where components are fed continuously from a reel. Cut Tape (CT) and Digi-Reel® formats are suitable for lower-volume production, manual assembly, or mixed-component orders. The electrical performance of the component is identical regardless of packaging format.

Q: Why is the TL7757IPKG3 classified as obsolete?

A: Product obsolescence typically results from manufacturer discontinuation decisions. The TL7757IPK remains in active production and serves as the current equivalent for new and ongoing applications.

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

A: No. Both the TL7757IPKG3 and TL7757IPK carry identical ROHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level (MSL) ratings. Regulatory and environmental certifications are equivalent.

Q: What is the significance of the 4.55V threshold voltage?

A: The 4.55V threshold voltage is the monitored supply voltage level at which the supervisor IC triggers a reset signal. This specification must match the system's power supply requirements and reset logic design. Both parts maintain this identical threshold.

Q: Can these parts be used interchangeably in high-volume production?

A: Yes, with consideration for packaging format. For automated assembly lines requiring Tape & Reel format, the TL7757IPKG3 is appropriate. For production environments using Cut Tape or Digi-Reel® formats, the TL7757IPK is the suitable choice. Electrical performance is identical in both cases.
