TUSB2077APTG4 Equivalent & Substitute Parts

Part Overview

The TUSB2077APTG4 is a USB Hub Controller IC manufactured by Texas Instruments, designed for USB 2.0 interface applications. This device integrates hub control functionality in a 48-LQFP (7x7) package and operates within a 3V to 3.6V supply voltage range. The TUSB2077APTG4 is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TUSB2077APTG4 is determined by strict equivalence across the following parameters:

• Functional Equivalence: Hub Controller function for USB 2.0 protocol
• Electrical Compatibility: Identical supply voltage range (3V to 3.6V) and current specification (20mA)
• Package Compatibility: 48-LQFP (7x7) package footprint and pinout
• Operating Conditions: Matching temperature range (0°C to 70°C)
• Regulatory Compliance: ROHS3 compliance and identical MSL rating (3, 168 Hours)

The TUSB2077APT meets all these criteria as a parametric equivalent, with the primary distinction being packaging format (Tray versus the original LQFP tube packaging) and active product status.

Parameter Comparison

Engineering Selection Recommendations

The TUSB2077APT is a direct parametric equivalent to the TUSB2077APTG4 across all electrical, mechanical, and thermal specifications. The substitute part maintains identical functional performance, package footprint, and regulatory compliance status. The primary distinction is product lifecycle status: the TUSB2077APTG4 is obsolete, while the TUSB2077APT remains in active production by Texas Instruments. For new designs or ongoing procurement requirements, the TUSB2077APT is the appropriate selection. Both parts carry ROHS3 compliance and identical moisture sensitivity ratings, ensuring compatibility with standard PCB assembly and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the TUSB2077APT be used as a direct replacement for the TUSB2077APTG4 in existing designs?

A: Yes. Both parts share identical electrical specifications, package geometry (48-LQFP 7x7), and functional characteristics. No circuit modifications are required.

Q: What is the difference between the TUSB2077APTG4 and TUSB2077APT?

A: The parts are electrically and functionally equivalent. The primary difference is packaging format: TUSB2077APTG4 uses standard LQFP tube packaging, while TUSB2077APT is supplied in Tray format. Additionally, TUSB2077APT maintains active product status from Texas Instruments.

Q: Are there any thermal or voltage differences between these parts?

A: No. Both parts operate within the identical supply voltage range (3V to 3.6V), draw the same supply current (20mA), and support the same operating temperature range (0°C to 70°C).

Q: What does the obsolete status of TUSB2077APTG4 mean for procurement?

A: Obsolete status indicates Texas Instruments has discontinued production. The TUSB2077APT, as an active equivalent, is the recommended source for new procurement and design continuity.

Q: Are moisture sensitivity and RoHS compliance identical?

A: Yes. Both parts carry MSL rating 3 (168 Hours) and ROHS3 compliance, ensuring identical handling, storage, and environmental requirements.
