Engineering Selection Recommendations

All substitute parts maintain Active product status from Texas Instruments and comply with ROHS3 and REACH requirements. Selection between TPS709A30DBVR and its substitutes is determined by packaging format availability and inventory requirements:

TPS70930DBVR and TPS70930DBVT are supplied in Cut Tape (CT) & Digi-Reel® format, suitable for automated assembly processes requiring reel-based component feeding. TPS709A30DBVT is supplied in Tape & Reel (TR) format, matching the original TPS709A30DBVR packaging specification. All parts are electrically and mechanically identical, ensuring direct substitution without circuit redesign or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can TPS70930DBVR replace TPS709A30DBVR in production assembly?

A: Yes. Both parts are electrically identical with matching output voltage (3V), output current (150mA), dropout voltage (1.4V @ 150mA), and operating temperature range (-40°C ~ 125°C). The primary difference is packaging format: TPS70930DBVR uses Cut Tape (CT) & Digi-Reel® while TPS709A30DBVR uses Tape & Reel (TR). Both are Surface Mount SOT-23-5 packages suitable for automated pick-and-place assembly.

Q: What is the difference between TPS70930DBVT and TPS70930DBVR?

A: These parts are electrically identical. The difference is packaging format: DBVR is supplied in Cut Tape (CT) & Digi-Reel® format, while DBVT is also supplied in Cut Tape (CT) & Digi-Reel® format. Both maintain identical electrical specifications and SOT-23-5 package dimensions.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts (TPS70930DBVR, TPS70930DBVT, TPS709A30DBVT) are ROHS3 Compliant and REACH Unaffected, matching the compliance status of the original TPS709A30DBVR.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All substitute parts share identical SOT-23-5 package dimensions (SC-74A, SOT-753 case), pin configuration, and electrical specifications. Direct PCB footprint compatibility is guaranteed without layout modifications.

Q: What is the operating temperature range for all substitute parts?

A: All parts operate across -40°C to 125°C, supporting industrial and commercial temperature applications without performance variation.
