USB5826C/KD Equivalent & Substitute Parts

Part Overview

The USB5826C/KD is an active USB Hub Controller from Microchip Technology designed for USB 2.0 and USB 3.1 applications. This interface component operates as a hub control IC with multi-protocol support including I2C, SMBus, SPI, and UART. The part is in active product status with full RoHS3 compliance and REACH unaffected classification. Equivalent substitute parts are necessary when primary inventory is unavailable or when design flexibility across compatible controller variants is required within the same functional and electrical specifications.

Substitute Part Grouping Explanation

The USB5826C/KD has three parametric equivalent substitutes: USB5906C/KD, USB5916C/KD, and USB5926C/KD. All substitute parts share identical electrical and mechanical specifications that determine substitution eligibility:

Key Parameters for Substitution:

• Identical USB protocol support (USB 2.0, USB 3.1)
• Identical interface protocols (I2C, SMBus, SPI, UART)
• Identical supply voltage ranges (1.08V ~ 1.32V, 3V ~ 3.6V)
• Identical operating temperature range (0°C ~ 70°C)
• Identical package specification (100-VQFN 12x12 with Exposed Pad)
• Identical compliance certifications (ROHS3, REACH Unaffected, EAR99)
• Identical MSL rating (3, 168 Hours)

These parts are functionally interchangeable at the circuit level and can be substituted without design modification.

Parameter Comparison

Engineering Selection Recommendations

All four parts—USB5826C/KD, USB5906C/KD, USB5916C/KD, and USB5926C/KD—maintain active product status with identical compliance certifications. Selection between these parts should be based on inventory availability and supply chain requirements. All parts carry ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory standards. The 100-VQFN package with exposed pad is consistent across all variants, ensuring PCB layout compatibility. MSL rating of 3 applies uniformly, requiring standard moisture control during storage and assembly.

Frequently Asked Questions (FAQ)

Q: Can USB5906C/KD, USB5916C/KD, and USB5926C/KD be used interchangeably with USB5826C/KD?

A: Yes. All three substitute parts share identical electrical specifications, interface protocols, supply voltage ranges, operating temperature ranges, and package dimensions. They are parametric equivalents suitable for direct substitution without circuit design modification.

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

A: No. All four parts carry identical RoHS3 compliance, REACH unaffected status, EAR99 ECCN classification, and MSL rating of 3 (168 Hours). Regulatory and environmental compliance is uniform across all variants.

Q: What is the significance of the 100-VQFN (12x12) package specification?

A: This package designation specifies a 100-pin Very Thin Quad Flat No-Lead package with 12mm x 12mm footprint and exposed pad. All substitute parts use this identical package, ensuring PCB footprint and reflow compatibility without layout redesign.

Q: How should MSL rating 3 (168 Hours) be interpreted for component handling?

A: MSL 3 indicates the component can be exposed to moisture for up to 168 hours at specified humidity and temperature conditions before soldering. Standard moisture control procedures during storage and assembly are required to maintain component reliability.

Q: Are there functional differences between USB5826C/KD and its substitutes?

A: No functional differences exist. All parts implement identical USB 2.0 and USB 3.1 hub controller functionality with I2C, SMBus, SPI, and UART interface support. Selection is based on availability and supply chain considerations only.
