• Package / Case: SC-74A, SOT-753 (SOT-23-5 supplier package)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Electrical Performance Parameters (must meet or exceed LM7301IM5 specifications):

• Slew Rate: ≥ 1.25 V/µs
• Gain Bandwidth Product: ≥ 4 MHz
• Current - Input Bias: ≤ 103 nA
• Voltage - Input Offset: ≤ 40 µV
• Current - Supply: ≤ 720 µA
• Current - Output / Channel: ≥ 11.7 mA
• Voltage - Supply Span (Min): ≤ 1.8 V
• Voltage - Supply Span (Max): ≥ 32 V
• Operating Temperature Range: Must include -40°C to 85°C minimum

Substitute parts are grouped into two categories: Direct Equivalents and Manufacturer-Recommended Alternatives. Direct equivalents maintain identical electrical specifications and product lineage. Manufacturer-recommended alternatives provide enhanced performance characteristics while maintaining functional compatibility within the same package and compliance framework.

Engineering Selection Recommendations

LM7301IM5/NOPB (Direct Equivalent)

The LM7301IM5/NOPB is the recommended primary substitute for the obsolete LM7301IM5. This part maintains identical electrical specifications and performance characteristics while carrying Active product status. The LM7301IM5/NOPB is the lead-free, halogen-free variant of the original LM7301IM5 and represents the direct continuation of this product line from Texas Instruments. With 37,221 units in current inventory, this part provides immediate supply availability and design continuity. Selection of LM7301IM5/NOPB eliminates the need for circuit redesign or performance re-qualification.

MAX44241AUK+T (Manufacturer-Recommended Alternative)

The MAX44241AUK+T is an active, manufacturer-recommended alternative from Analog Devices Inc./Maxim Integrated. This part exceeds the electrical performance specifications of the LM7301IM5 across multiple parameters: slew rate of 3.8 V/µs (versus 1.25 V/µs), gain bandwidth product of 5 MHz (versus 4 MHz), input bias current of 0.3 pA (versus 103 nA), input offset voltage of 1 µV (versus 40 µV), and output current capability of 40 mA (versus 11.7 mA). The MAX44241AUK+T also features lower supply current consumption at 420 µA. Operating temperature range extends to 125°C, and supply voltage span extends to 36 V maximum. All parts maintain identical package form factor (SOT-23-5), surface mount mounting type, and compliance certifications (ROHS3, MSL 1). Selection of MAX44241AUK+T is appropriate for applications requiring enhanced performance margins or extended operating temperature range, provided circuit design accommodates the improved electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can the LM7301IM5/NOPB be used as a direct replacement for the LM7301IM5?

A: Yes. The LM7301IM5/NOPB is electrically and mechanically identical to the LM7301IM5. Both parts share identical electrical specifications, package form factor (SOT-23-5), and compliance certifications. The primary difference is product status: LM7301IM5/NOPB is Active, while LM7301IM5 is Obsolete. No circuit modifications are required for substitution.

Q: What are the key differences between the LM7301IM5 and MAX44241AUK+T?

A: The MAX44241AUK+T provides superior electrical performance in several areas: 3.04× higher slew rate (3.8 V/µs vs. 1.25 V/µs), 25% higher gain bandwidth product (5 MHz vs. 4 MHz), significantly lower input bias current (0.3 pA vs. 103 nA), lower input offset voltage (1 µV vs. 40 µV), 3.4× higher output current capability (40 mA vs. 11.7 mA), and 42% lower supply current (420 µA vs. 720 µA). Operating temperature range extends to 125°C. Both parts use identical SOT-23-5 packaging and maintain ROHS3 compliance.

Q: Are all three parts pin-compatible?

A: Yes. The LM7301IM5, LM7301IM5/NOPB, and MAX44241AUK+T all use the SC-74A, SOT-753 package (SOT-23-5 supplier designation), which provides identical pinout and footprint compatibility. Direct PCB substitution is possible without layout modifications.

Q: Which substitute part should be selected for new designs?

A: For new designs, the LM7301IM5/NOPB is the recommended choice, as it maintains the original electrical specifications and performance characteristics while offering Active product status and established supply chain availability. The MAX44241AUK+T should be selected only if the enhanced performance characteristics (higher slew rate, lower input offset voltage, higher output current, extended temperature range) provide specific design advantages or margin improvements for the target application.

Q: What is the inventory status for each part?

A: LM7301IM5 (Obsolete): 2,806 units in stock. LM7301IM5/NOPB (Active): 37,221 units in stock. MAX44241AUK+T (Active): 2,100 units in stock. The LM7301IM5/NOPB offers the highest inventory availability.

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts maintain identical compliance certifications: ROHS3 Compliant, Moisture Sensitivity Level 1 (Unlimited), REACH Unaffected status, and identical ECCN and HTSUS classifications. All parts are suitable for applications requiring these compliance standards.

Q: Can the MAX44241AUK+T be used in applications originally designed for the LM7301IM5?

A: The MAX44241AUK+T is electrically compatible and can be substituted in most applications. However, the enhanced performance characteristics (higher slew rate, lower input offset voltage, higher output current) may affect circuit behavior in applications with tight feedback networks or precision offset-dependent designs. Circuit verification is recommended for applications with critical offset voltage or slew rate dependencies.
