Substitute Part Grouping Explanation

Substitution eligibility for the SN65220DBVT is determined by strict alignment of the following critical parameters:

• Voltage - Clamping: 7V (exact match required)
• Technology: Mixed Technology (exact match required)
• Number of Circuits: 1 (exact match required)
• Package / Case: SOT-23-6 (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Applications: USB (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The SN65220DBVR meets all substitution criteria and is classified as a direct equivalent for the SN65220DBVT.

Parameter Comparison

Engineering Selection Recommendations

The SN65220DBVR is a direct functional equivalent to the SN65220DBVT. Both parts share identical electrical specifications, package geometry, and compliance certifications. The primary distinction is product status: the SN65220DBVT is in Last Time Buy status with limited inventory (60,300 pcs), while the SN65220DBVR maintains Active status with significantly higher availability (354,226 pcs). For new designs or production continuity, the SN65220DBVR is the appropriate selection. Both parts satisfy ROHS3 compliance and REACH requirements, ensuring regulatory alignment for circuit protection applications in USB systems.

Frequently Asked Questions (FAQ)

Q: Can the SN65220DBVR directly replace the SN65220DBVT in existing designs?

A: Yes. Both parts are manufactured by Texas Instruments, share the same base product number (SN65220), and possess identical electrical parameters (7V clamping voltage, mixed technology), circuit count (1), package type (SOT-23-6), and compliance certifications. Direct substitution is supported without design modification.

Q: What is the significance of the Last Time Buy status for the SN65220DBVT?

A: Last Time Buy status indicates that the SN65220DBVT will no longer be manufactured after existing inventory is depleted. Designers should transition to the SN65220DBVR to ensure long-term supply availability and production continuity.

Q: Are there any differences in moisture sensitivity or handling requirements between these parts?

A: No. Both the SN65220DBVT and SN65220DBVR carry an MSL rating of 1 (Unlimited), indicating identical moisture sensitivity levels and identical storage and handling requirements.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8542.39.0001. Regulatory requirements are identical.

Q: Is the SOT-23-6 package footprint identical between both parts?

A: Yes. Both parts use the SOT-23-6 surface mount package with identical mechanical and electrical pin configurations, supporting direct PCB layout compatibility.
