Engineering Selection Recommendations

Primary Substitute: LM7301IM5X/NOPB

The LM7301IM5X/NOPB is the direct functional equivalent of the obsolete LM7301IM5X. This part is manufactured by Texas Instruments and maintains identical electrical specifications across all measured parameters. The key distinction is product status: LM7301IM5X/NOPB carries active product status, ensuring ongoing manufacturing support and supply chain availability.

Both parts are ROHS3 compliant and carry MSL 1 rating, indicating equivalent environmental handling requirements. The /NOPB designation indicates lead-free plating, consistent with modern manufacturing standards.

For applications currently using the LM7301IM5X, direct substitution with LM7301IM5X/NOPB requires no circuit modifications, PCB layout changes, or firmware updates. Pin configuration, electrical performance, and thermal characteristics remain identical.

Frequently Asked Questions (FAQ)

Q: Can LM7301IM5X/NOPB be used as a direct replacement for LM7301IM5X?

A: Yes. Both parts are manufactured by Texas Instruments and share identical electrical specifications, package configuration (SOT-23-5), and operating characteristics. The primary difference is product status: LM7301IM5X/NOPB is active, while LM7301IM5X is obsolete.

Q: What does the /NOPB designation mean?

A: The /NOPB suffix indicates "No Plumbum" (lead-free). This refers to the lead-free plating used on the component leads, consistent with RoHS3 compliance requirements.

Q: Are there any differences in pin configuration between these parts?

A: No. Both parts use the SOT-23-5 package with identical pin assignments. PCB layouts designed for LM7301IM5X are directly compatible with LM7301IM5X/NOPB without modification.

Q: What is the operating temperature range for both parts?

A: Both the LM7301IM5X and LM7301IM5X/NOPB operate across the temperature range of -40°C to 85°C.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity level rating.

Q: What is the supply voltage range for these operational amplifiers?

A: Both parts operate with a supply voltage span from 1.8 V (minimum) to 32 V (maximum), supporting single-supply and dual-supply configurations.

Q: What are the key electrical characteristics that define substitution compatibility?

A: Substitution is based on matching: amplifier type (General Purpose), circuit count (1), output type (Rail-to-Rail), slew rate (1.25 V/µs), gain bandwidth product (4 MHz), input bias current (103 nA), input offset voltage (40 µV), supply current (720 µA), and operating temperature range (-40°C to 85°C).
