Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the USB5906CT-I/KD are qualified based on strict parametric equivalence across the following criteria:

Electrical Compatibility: All substitute parts maintain identical voltage supply ranges (1.08V ~ 1.32V, 3V ~ 3.6V) and operating temperature specifications (-40°C ~ 85°C). USB protocol support (USB 2.0, USB 3.1) and interface functionality (I2C, SMBus, SPI, UART) are identical across all qualified substitutes.

Mechanical Compatibility: All substitute parts use the identical 100-VQFN (12x12) package with exposed pad configuration and Tape & Reel packaging format, ensuring direct PCB footprint compatibility.

Regulatory Compliance: All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and identical Moisture Sensitivity Level (MSL 3, 168 Hours), meeting the same environmental and regulatory requirements as the original part.

Qualifying Substitute Parts: USB5826CT-I/KD, USB5916CT-I/KD, USB5926CT-I/KD

Parameter Comparison

Engineering Selection Recommendations

All parts maintain identical electrical specifications, package geometry, and regulatory certifications, supporting direct substitution in existing designs.

Frequently Asked Questions (FAQ)

Q: Can USB5826CT-I/KD, USB5916CT-I/KD, and USB5926CT-I/KD be used interchangeably with USB5906CT-I/KD?

A: Yes. All substitute parts share identical electrical specifications (voltage supply, operating temperature, USB standards, and interface protocols), mechanical packaging (100-VQFN with exposed pad), and regulatory compliance (ROHS3, REACH Unaffected, MSL 3). Direct PCB footprint compatibility is confirmed.

Q: Are there any differences in the 100-VQFN package between the main part and substitutes?

A: No. All parts use the identical 100-VQFN (12x12) package configuration with exposed pad and Tape & Reel packaging format. Pin count, pitch, and thermal characteristics are equivalent.

Q: Do all substitute parts support the same USB protocols and interface types?

A: Yes. All parts support USB 2.0 and USB 3.1 standards with identical I2C, SMBus, SPI, and UART interface capabilities.

Q: What is the Moisture Sensitivity Level for these parts, and does it affect handling?

A: All parts carry MSL 3 rating with a 168-hour floor life. This classification requires standard moisture control during storage and handling per IPC-A-610 guidelines.

Q: Are all substitute parts currently in active production?

A: Yes. All qualified substitute parts maintain active product status with Microchip Technology.
