TL7700CPWRG4 Equivalent & Substitute Parts

Part Overview

The TL7700CPWRG4 is a supervisor integrated circuit designed for power management applications, specifically functioning as a simple reset or power-on reset controller. This device monitors a single voltage channel and provides active-low reset output through an open-drain or open-collector configuration. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain electrical and mechanical compatibility for ongoing system support and new designs.

Substitute Part Grouping Explanation

Substitution of the TL7700CPWRG4 is determined by strict equivalence across the following critical parameters:

• Functional Type: Simple reset/power-on reset supervisor with single-channel voltage monitoring
• Output Configuration: Open drain or open collector output with active-low reset logic
• Electrical Specifications: 10µs maximum propagation delay, adjustable/selectable voltage threshold
• Package Compatibility: 8-TSSOP surface-mount package with identical physical dimensions (0.173", 4.40mm width)
• Environmental Compliance: ROHS3 compliance, MSL Level 1, operating temperature range -40°C to 85°C
• Base Product Series: TL7700 family designation

The TL7700CPWR qualifies as a direct substitute based on identical electrical characteristics, package specifications, and compliance certifications. The primary distinction is packaging format: the main part uses Tape & Reel (TR) packaging, while the substitute uses Cut Tape (CT) & Digi-Reel® packaging. Both derive from the same base product number and maintain full functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The TL7700CPWR is the recommended substitute for the discontinued TL7700CPWRG4. Both parts maintain identical electrical and mechanical specifications, ensuring direct functional compatibility in existing designs. The substitute part carries active product status, providing assured availability and supply chain continuity. Both parts meet ROHS3 compliance and carry equivalent environmental certifications (REACH Unaffected, ECCN EAR99, HTSUS 8542.39.0001), supporting regulatory requirements across global markets.

The packaging format difference—Tape & Reel versus Cut Tape & Digi-Reel—does not affect electrical performance or PCB assembly compatibility. Selection between these packaging options depends on procurement volume and assembly process requirements rather than technical performance criteria.

Frequently Asked Questions (FAQ)

Q: Can the TL7700CPWR be used as a direct replacement for the TL7700CPWRG4?

A: Yes. Both parts share identical electrical specifications, package dimensions, and functional characteristics. The TL7700CPWR is electrically and mechanically interchangeable with the TL7700CPWRG4.

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

A: Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® represent different packaging and delivery formats. Tape & Reel is supplied on continuous carrier tape in reel format, typically for high-volume automated assembly. Cut Tape & Digi-Reel® provides the same components in smaller quantities on cut tape segments. Both formats contain identical components with no electrical or performance differences.

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

A: No. Both the TL7700CPWRG4 and TL7700CPWR carry identical RoHS3 compliance, MSL Level 1 rating, REACH Unaffected status, and equivalent trade classification codes. They meet the same regulatory and environmental standards.

Q: Why is the TL7700CPWRG4 discontinued?

A: Product discontinuation decisions are made by manufacturers and distributors based on market demand and supply chain optimization. The availability of the functionally equivalent TL7700CPWR ensures continued access to this supervisor IC functionality.

Q: What parameters must remain identical for substitution?

A: Critical parameters for substitution include: single-channel voltage monitoring, adjustable/selectable threshold, open-drain/open-collector output, active-low reset logic, 10µs propagation delay, 8-TSSOP package, -40°C to 85°C operating temperature range, and ROHS3 compliance. Any deviation in these parameters requires re-evaluation of compatibility.
