Engineering Selection Recommendations

The TPS54233DR is the manufacturer-recommended substitute for the discontinued TPS54233DRG4. Both parts maintain identical electrical and thermal specifications, ensuring functional equivalence in circuit applications.

Product Status Consideration: The TPS54233DRG4 is discontinued at DiGi Electronics, while the TPS54233DR maintains active product status with significantly higher inventory availability (35,400 pcs vs. 1,123 pcs). This availability differential supports long-term supply chain stability.

Compliance & Certification: Both parts carry ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity ratings (MSL 1 - Unlimited), confirming equivalent environmental and regulatory compliance.

Packaging Distinction: The primary difference is packaging format. The TPS54233DRG4 uses tube packaging, while TPS54233DR uses Tape & Reel (TR) format. This distinction affects handling, storage, and automated assembly processes but does not impact electrical performance or circuit functionality.

Frequently Asked Questions (FAQ)

Q: Can TPS54233DR be used as a direct replacement for TPS54233DRG4?

A: Yes. Both parts share identical electrical specifications, thermal ratings, and package dimensions. The only difference is packaging format (tube vs. Tape & Reel). Circuit performance and functionality remain unchanged.

Q: What is the difference between TPS54233DRG4 and TPS54233DR?

A: The devices are electrically and mechanically identical. TPS54233DRG4 is supplied in tube packaging, while TPS54233DR is supplied in Tape & Reel (TR) format. The packaging format affects procurement and assembly processes but not component performance.

Q: Why is TPS54233DRG4 discontinued?

A: The TPS54233DRG4 is discontinued at DiGi Electronics. The active equivalent TPS54233DR in Tape & Reel packaging remains available from Texas Instruments with higher inventory levels.

Q: Are there any circuit design changes required when switching from TPS54233DRG4 to TPS54233DR?

A: No circuit design changes are required. Both parts maintain identical pin configurations, electrical characteristics, and operating parameters. PCB layout and external component values remain unchanged.

Q: What packaging format should I select for new designs?

A: For new designs, TPS54233DR (Tape & Reel format) is recommended due to active product status and higher inventory availability. Tape & Reel packaging is standard for automated assembly processes.

Q: Do both parts have the same RoHS and REACH compliance?

A: Yes. Both TPS54233DRG4 and TPS54233DR are ROHS3 compliant and REACH unaffected, maintaining identical environmental compliance certifications.
