Substitute Part Grouping Explanation

Substitution eligibility for the SN75DP128RTQR is determined by strict alignment of the following critical parameters:

  • Base Product Number: Must be 75DP128 to ensure functional equivalence
  • Interface Type: Must be I2C
  • Voltage Supply Range: Must be 4.5V ~ 5.25V
  • Package / Case: Must be 56-VFQFN Exposed Pad
  • Supplier Device Package: Must be 56-QFN (8x8)
  • Mounting Type: Must be Surface Mount
  • RoHS Status: Must be ROHS3 Compliant
  • Moisture Sensitivity Level: Must be 3 (168 Hours)
  • REACH Status: Must be REACH Unaffected

The SN75DP128ARTQT meets all substitution criteria as a direct equivalent part. The primary distinction between these parts is product status: the main part (RTQR) is in Last Time Buy status, while the substitute (ARTQT) maintains Active status, ensuring continued availability.

Frequently Asked Questions (FAQ)

Q: Can the SN75DP128ARTQT be used as a direct replacement for the SN75DP128RTQR?

A: Yes. Both parts are functionally equivalent with identical I2C interface specifications, 4.5V ~ 5.25V supply voltage range, 56-QFN (8x8) package configuration, and all regulatory compliance certifications. The primary difference is product lifecycle status.

Q: What is the significance of the Last Time Buy status on the SN75DP128RTQR?

A: Last Time Buy status indicates that the manufacturer has ceased production and will no longer accept new orders after a specified cutoff date. The SN75DP128ARTQT, with Active status, remains in production and is available for ongoing procurement.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the identical 56-VFQFN Exposed Pad package with 56-QFN (8x8) configuration and surface mount mounting type. Pinout and mechanical dimensions are identical.

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

A: Yes. Both the SN75DP128RTQR and SN75DP128ARTQT are ROHS3 compliant, REACH unaffected, and have identical Moisture Sensitivity Level (MSL) ratings of 3 (168 Hours).

Q: What is the inventory status of these parts?

A: The SN75DP128RTQR has 2325 pieces in stock as new original inventory. The SN75DP128ARTQT has 1249 pieces in stock as new original inventory. Availability may vary based on current demand and supplier stock levels.
