Engineering Selection Recommendations

Direct Replacement (Identical Electrical Performance):

LMP7701MF/NOPB is the direct equivalent to LMP7701MF. Both parts are manufactured by Texas Instruments with identical electrical specifications. LMP7701MF/NOPB carries Active product status and is currently in production, making it the preferred choice for new designs and long-term availability. This part requires no circuit redesign or validation.

Functional Substitutes (Active Production, Full Temperature Range):

TS951ILT and TS951IYLT, manufactured by STMicroelectronics, are functionally compatible substitutes. Both maintain the -40°C to 125°C operating temperature range matching the original LMP7701MF specification. TS951IYLT includes AEC-Q100 automotive qualification. These parts feature higher gain bandwidth product (3 MHz versus 2.5 MHz) and comparable slew rate (1 V/µs versus 1.1 V/µs). Input offset voltage is higher (6 mV versus 37 µV), which may require circuit evaluation in precision applications.

TS9511ILT is also available from STMicroelectronics with similar performance characteristics and full temperature range support.

Limited Temperature Range Substitutes (Active Production):

LMC7101AYM5-TR and LMC7101BYM5-TR, manufactured by Microchip Technology, are functionally compatible but operate only to 85°C maximum, compared to the original 125°C specification. These parts are suitable for applications with reduced upper temperature requirements. Both offer higher output current capability (300 mA versus 86 mA).

MIC7300YM5-TR, also from Microchip Technology, operates to 85°C maximum and features a reduced supply voltage minimum of 2.2 V. This part is not suitable for applications requiring the full 2.7 V to 12 V supply range of the original LMP7701MF.

Product Status Consideration:

All substitute parts listed carry Active product status, ensuring continued manufacturing and availability. The original LMP7701MF is designated Last Time Buy, confirming the necessity of transition planning.

Frequently Asked Questions (FAQ)

Q: Can LMP7701MF/NOPB be used as a direct replacement for LMP7701MF?

A: Yes. LMP7701MF/NOPB is electrically and mechanically identical to LMP7701MF. Both are manufactured by Texas Instruments with the same electrical specifications, package type (SOT-23-5), and operating temperature range (-40°C to 125°C). LMP7701MF/NOPB is currently in active production.

Q: What is the difference between TS951ILT and TS951IYLT?

A: Both parts are manufactured by STMicroelectronics with identical electrical specifications and operating temperature range (-40°C to 125°C). TS951IYLT includes AEC-Q100 automotive qualification, making it suitable for automotive applications. TS951ILT is the standard industrial grade version.

Q: Can LMC7101AYM5-TR or LMC7101BYM5-TR be used in applications requiring 125°C operation?

A: No. Both LMC7101AYM5-TR and LMC7101BYM5-TR are rated to 85°C maximum operating temperature. They are not suitable for applications requiring the full -40°C to 125°C temperature range of the original LMP7701MF. Use TS951ILT, TS951IYLT, or TS9511ILT for full temperature range compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (LMP7701MF/NOPB, LMC7101AYM5-TR, LMC7101BYM5-TR, MIC7300YM5-TR, TS9511ILT, TS951ILT, and TS951IYLT) are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the packaging difference between Cut Tape (CT) and Tape & Reel (TR)?

A: Cut Tape (CT) and Digi-Reel® packaging are supplied as individual components cut from tape, suitable for lower-volume applications and manual assembly. Tape & Reel (TR) packaging supplies components on continuous tape in reel format, optimized for high-volume automated assembly. Both formats use the same SOT-23-5 package and are mechanically and electrically compatible.

Q: Which substitute part has the highest output current capability?

A: LMC7101AYM5-TR and LMC7101BYM5-TR both provide 300 mA output current per channel, compared to 86 mA for the original LMP7701MF. However, these parts are limited to 85°C maximum operating temperature.

Q: Can MIC7300YM5-TR be used as a substitute for LMP7701MF?

A: MIC7300YM5-TR is not recommended as a substitute. While it maintains the SOT-23-5 package and rail-to-rail output type, it operates only to 85°C maximum and has a reduced supply voltage minimum of 2.2 V (versus 2.7 V for LMP7701MF). Applications requiring the full 2.7 V to 12 V supply range cannot use this part.

Q: Are there any automotive-qualified alternatives to LMP7701MF?

A: Yes. TS951IYLT is AEC-Q100 qualified and suitable for automotive applications. It maintains the full -40°C to 125°C operating temperature range and 2.7 V to 12 V supply voltage range of the original LMP7701MF.
