LM201AH Equivalent & Substitute Parts

Part Overview

The LM201AH is a general-purpose operational amplifier manufactured by Texas Instruments, housed in a TO-99-8 metal can package for through-hole mounting. This single-circuit amplifier is classified as an active product with ROHS3 compliance and unlimited moisture sensitivity rating. The LM201AH serves applications requiring stable gain-bandwidth characteristics and moderate input bias current specifications across industrial temperature ranges. Substitute parts become necessary when addressing extended temperature operation requirements, alternative manufacturer sourcing, or specific packaging preferences while maintaining electrical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM201AH is determined by strict electrical and mechanical parameter matching within the general-purpose operational amplifier category. The critical parameters governing substitution are:

Electrical Compatibility Criteria:

• Slew Rate: 0.5 V/µs (fixed requirement)
• Gain Bandwidth Product: 1 MHz (fixed requirement)
• Current - Supply: 1.8 mA (fixed requirement)
• Voltage - Supply Span: 10 V minimum, 44 V maximum (fixed requirement)
• Number of Circuits: 1 (fixed requirement)

Mechanical Compatibility Criteria:

• Package / Case: TO-99-8 Metal Can (fixed requirement)
• Mounting Type: Through Hole (fixed requirement)

Allowable Parameter Variations: Substitute parts may differ in the following parameters while maintaining functional equivalence:

• Current - Input Bias: Range 30 nA to 70 nA
• Voltage - Input Offset: Range 700 µV to 2 mV
• Operating Temperature: Extended ranges acceptable (minimum -55°C, maximum 125°C)
• Manufacturer: National Semiconductor or Texas Instruments
• Packaging designation: Bulk or standard

All substitute parts listed maintain identical slew rate, gain-bandwidth product, supply current, supply voltage span, circuit count, and physical package specifications as the LM201AH.

Parameter Comparison

Engineering Selection Recommendations

LM101AH (National Semiconductor) This substitute provides extended operating temperature range (-55°C to 125°C) compared to the LM201AH (-25°C to 85°C). All electrical parameters remain identical. Selection is appropriate for applications requiring wider temperature operation from an alternative manufacturer source. ROHS3 compliance status is not specified for this part.

LM101AH/NOPB (Texas Instruments) This part is electrically and mechanically identical to the LM201AH with extended temperature range (-55°C to 125°C). The /NOPB designation indicates lead-free, RoHS3-compliant packaging. This substitute is suitable for designs requiring extended temperature performance while maintaining Texas Instruments sourcing and full compliance documentation.

LM201AH/NOPB (Texas Instruments) This is the lead-free variant of the LM201AH with identical electrical specifications and operating temperature range (-25°C to 85°C). The /NOPB designation confirms RoHS3 compliance and lead-free construction. Selection is appropriate when lead-free packaging is required without temperature range extension.

LM301AH/NOPB (Texas Instruments) This substitute exhibits higher input bias current (70 nA versus 30 nA) and higher input offset voltage (2 mV versus 700 µV). Maximum supply voltage is reduced to 36 V (from 44 V). Operating temperature range is narrower (0°C to 70°C). Selection requires verification that the application tolerates these parameter deviations. This part is suitable only when the reduced temperature range and relaxed input specifications are acceptable.

Frequently Asked Questions (FAQ)

Q: Can LM101AH replace LM201AH in all applications? A: LM101AH provides identical electrical performance with extended temperature range (-55°C to 125°C versus -25°C to 85°C). Substitution is valid for all applications where the LM201AH operates within its specified temperature range. Applications requiring temperatures below -25°C or above 85°C benefit from LM101AH extended range.

Q: What is the difference between LM201AH and LM201AH/NOPB? A: Both parts are electrically identical with matching operating temperature range (-25°C to 85°C). The /NOPB designation indicates lead-free, RoHS3-compliant construction. Selection depends on regulatory or procurement requirements for lead-free components.

Q: Is LM301AH/NOPB a direct substitute for LM201AH? A: LM301AH/NOPB is not a direct substitute. Input bias current is higher (70 nA versus 30 nA), input offset voltage is higher (2 mV versus 700 µV), and maximum supply voltage is lower (36 V versus 44 V). Operating temperature range is also narrower (0°C to 70°C). Substitution requires application-level verification that these parameter differences are acceptable.

Q: Why would I choose LM101AH/NOPB over LM201AH/NOPB? A: LM101AH/NOPB extends operating temperature range to -55°C to 125°C, compared to LM201AH/NOPB at -25°C to 85°C. All other electrical parameters are identical. Selection depends on whether the application requires operation outside the LM201AH temperature range.

Q: Are all substitute parts available in the same TO-99-8 package? A: Yes. All listed substitute parts use TO-99-8 metal can through-hole packaging, ensuring mechanical and pin-compatible installation with the LM201AH.

Q: What compliance certifications apply to these parts? A: LM201AH/NOPB, LM101AH/NOPB, and LM301AH/NOPB are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). All parts are REACH unaffected and classified under ECCN EAR99 and HTSUS 8542.33.0001.
