Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLK106RHBT is determined by the following critical parameters:

• Protocol Compatibility: Both MII and RMII protocol support are required
• Package Compatibility: 32-VFQFN Exposed Pad (5x5) surface mount package
• Electrical Specifications: Supply voltage range and operating temperature range must accommodate the original design requirements
• Configuration: 1/1 driver/receiver configuration
• Compliance Standards: RoHS3 compliance and MSL rating consistency

The DP83822IRHBT meets these substitution criteria through matching protocol support, identical package specifications, compatible voltage and temperature ranges, and equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The DP83822IRHBT is the qualified substitute for the TLK106RHBT based on the following engineering criteria:

• Protocol Equivalence: Identical MII and RMII protocol support ensures functional compatibility in existing system architectures
• Electrical Compatibility: The DP83822IRHBT supply voltage range (1.71V ~ 3.45V) encompasses the TLK106RHBT operating range (3V ~ 3.6V), providing electrical compatibility
• Compliance Alignment: Both devices maintain ROHS3 compliance and identical MSL ratings, ensuring manufacturing and environmental compliance consistency
• Active Product Status: The DP83822IRHBT is classified as Active, providing ongoing manufacturer support, availability, and technical documentation access

Frequently Asked Questions (FAQ)

Q: Can the DP83822IRHBT be used as a direct replacement for the TLK106RHBT without PCB modifications?

A: Yes. Both devices share the identical 32-VFQFN (5x5) Exposed Pad package with matching pinout and footprint specifications, enabling direct substitution without PCB layout changes.

Q: Are there voltage compatibility concerns when substituting the DP83822IRHBT for the TLK106RHBT?

A: No. The DP83822IRHBT supply voltage range (1.71V ~ 3.45V) fully encompasses the TLK106RHBT operating range (3V ~ 3.6V). Designs operating within the original 3V to 3.6V specification will function within the DP83822IRHBT electrical envelope.

Q: What is the primary advantage of selecting the DP83822IRHBT over the TLK106RHBT?

A: The DP83822IRHBT carries Active product status with ongoing manufacturer support, ensuring long-term availability, technical documentation, and supply chain continuity compared to the TLK106RHBT, which is classified as Not For New Designs.

Q: Do both devices support the same communication protocols?

A: Yes. Both the TLK106RHBT and DP83822IRHBT support MII and RMII protocols, ensuring functional compatibility in systems requiring these interface standards.

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

A: No. Both devices maintain ROHS3 compliance, carry identical MSL ratings of 2 (1 Year), and share equivalent environmental and regulatory certifications.
