USB5816CT/KD Equivalent & Substitute Parts

Part Overview

The USB5816CT/KD is an active USB Hub Controller from Microchip Technology designed for USB 3.1 applications requiring I2C and SPI interface control. This interface IC operates across dual voltage domains (1.08V–1.32V and 3V–3.6V) and is packaged in a 100-VQFN form factor with exposed pad. The part maintains active product status and full RoHS3 compliance, making it suitable for current production designs. Equivalent substitute parts are available to address inventory availability, packaging format preferences, or supply chain optimization requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the USB5816CT/KD is determined by strict equivalence across the following parameters:

• Manufacturer: Microchip Technology (all substitutes from same manufacturer)
• Protocol & Function: USB Hub Controller with identical protocol specification
• Interface Type: I2C and SPI dual interface support
• Standards Compliance: USB 3.1 standard
• Electrical Specifications: Identical dual voltage supply ranges (1.08V–1.32V and 3V–3.6V)
• Operating Temperature Range: 0°C–70°C
• Package Form Factor: 100-VQFN (12x12) with exposed pad
• Regulatory Compliance: ROHS3, REACH Unaffected, EAR99 classification

The USB5806CT/KD and USB5807CT/KD meet all substitution criteria. Differentiation between parts is limited to packaging format (Tape & Reel vs. Cut Tape & Digi-Reel) and inventory availability, with no functional or electrical parameter variance.

Parameter Comparison

Engineering Selection Recommendations

All three parts—USB5816CT/KD, USB5806CT/KD, and USB5807CT/KD—are functionally and electrically equivalent for USB 3.1 hub controller applications. Selection between them is determined by:

Packaging Format: USB5816CT/KD and USB5806CT/KD are supplied in Tape & Reel format suitable for automated assembly lines. USB5807CT/KD is supplied in Cut Tape & Digi-Reel format, appropriate for lower-volume or manual assembly workflows.

Inventory Availability: USB5807CT/KD offers the highest stock level (7147 Pcs), followed by USB5806CT/KD (5497 Pcs) and USB5816CT/KD (2100 Pcs). Selection based on supply chain requirements and lead time constraints is valid.

Regulatory Compliance: All parts maintain identical RoHS3, REACH, and ECCN classifications, ensuring compliance equivalence across design and manufacturing phases.

Product Status: All parts maintain active product status, confirming long-term availability and manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can USB5806CT/KD or USB5807CT/KD be used as direct replacements for USB5816CT/KD in production?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, interface protocols, voltage supply ranges, operating temperature, and package form factor. No circuit redesign or PCB modification is required.

Q: What is the difference between the three parts?

A: The functional and electrical specifications are identical. The only differences are packaging format (Tape & Reel vs. Cut Tape & Digi-Reel) and current inventory levels. Base product numbers (USB5816, USB5806, USB5807) indicate internal Microchip product line variants with no functional distinction.

Q: Are there any compatibility concerns when switching between these parts?

A: No. All three parts use the same 100-VQFN (12x12) package with exposed pad, identical pinout, and identical electrical characteristics. PCB footprints, solder profiles, and assembly processes are interchangeable.

Q: Do all three parts meet the same regulatory requirements?

A: Yes. All parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Moisture sensitivity level (MSL 3, 168 hours) is identical across all three parts.

Q: Which part should I select if inventory is a concern?

A: USB5807CT/KD has the highest available inventory (7147 Pcs), followed by USB5806CT/KD (5497 Pcs). If packaging format requirements allow Cut Tape & Digi-Reel supply, USB5807CT/KD is the optimal choice for supply chain security.

Q: Are there any performance differences between these parts?

A: No. All three parts operate identically across the specified voltage ranges (1.08V–1.32V and 3V–3.6V), temperature range (0°C–70°C), and USB 3.1 protocol implementation. Performance is equivalent.
