USB2502-HT Equivalent & Substitute Parts

Part Overview

The USB2502-HT is a USB Hub Controller manufactured by Microchip Technology, designed to manage USB 2.0 interface operations in a 48-TQFP package. This component functions as a hub controller for USB connectivity applications requiring multi-port management capabilities.

The USB2502-HT has reached obsolete product status. Identifying functionally equivalent substitute components is necessary to maintain design continuity and ensure supply chain availability for new production runs and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for USB hub controller components is determined by the following parameters:

• Functional Equivalence: Both parts must operate as USB 2.0 hub controllers
• Package Compatibility: Physical package must be compatible with existing PCB layouts (48-pin LQFP/TQFP variants)
• Electrical Specifications: Supply voltage range and operating temperature must support the application requirements
• Interface Protocol: USB 2.0 protocol compliance is mandatory
• Regulatory Compliance: RoHS3 compliance status ensures environmental and material standards alignment

The TUSB2077APT from Texas Instruments meets these substitution criteria as an active-status USB 2.0 hub controller in a compatible 48-LQFP package with matching protocol and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The TUSB2077APT qualifies as a functional substitute for the USB2502-HT based on the following engineering criteria:

• Protocol Alignment: Both components implement USB 2.0 hub controller functionality with identical interface specifications
• Package Compatibility: The 48-LQFP package is mechanically and electrically compatible with 48-TQFP footprints in standard PCB designs
• Regulatory Status: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity
• Active Availability: The TUSB2077APT maintains active product status with documented inventory, providing supply chain reliability
• Operating Range: The overlapping temperature range (0°C ~ 70°C) and compatible voltage window (3V ~ 3.6V overlap) support equivalent application deployment

The TUSB2077APT demonstrates lower supply current consumption (20mA versus 100mA), which may provide secondary benefits in power-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can the TUSB2077APT directly replace the USB2502-HT in existing designs?

A: Yes, the TUSB2077APT is functionally equivalent for USB 2.0 hub controller applications. Both components share identical protocol standards, compatible package geometries (48-pin LQFP/TQFP), and overlapping operating specifications. PCB layout verification is recommended to confirm footprint compatibility.

Q: What are the key differences between these components?

A: The primary differences are manufacturer origin (Microchip versus Texas Instruments), product status (obsolete versus active), supply current specification (100mA versus 20mA), and moisture sensitivity rating (MSL 1 versus MSL 3). Functional USB 2.0 hub controller operation remains equivalent.

Q: Is the voltage range difference significant?

A: The USB2502-HT supports 1.62V ~ 3.6V while the TUSB2077APT supports 3V ~ 3.6V. If your application requires operation below 3V, the USB2502-HT specification is broader. For standard 3.3V or 3.6V supply designs, both components operate within compatible ranges.

Q: What does the moisture sensitivity level difference mean?

A: MSL 1 (USB2502-HT) indicates unlimited shelf life without moisture precautions. MSL 3 (TUSB2077APT) requires controlled storage conditions with a 168-hour floor life after packaging opening. This affects component handling and storage protocols but does not impact functional performance.

Q: Are there any compliance concerns with substitution?

A: Both components maintain ROHS3 compliance and REACH unaffected status. No compliance barriers exist for substitution in regulated applications.
