LM201AN Equivalent & Substitute Parts

Part Overview

The LM201AN is a general-purpose operational amplifier manufactured by onsemi, housed in an 8-DIP through-hole package. This device is classified as obsolete, though 1,678 units remain in current inventory. The LM201AN operates across a wide supply voltage range (10V to 44V) and is suitable for general-purpose amplification applications requiring moderate slew rate performance.

Due to its obsolete product status, identifying equivalent and substitute parts is essential for design continuity, long-term availability assurance, and production planning. Substitute parts must maintain electrical compatibility within the specified parameter tolerances while accommodating different packaging formats and manufacturing standards.

Substitute Part Grouping Explanation

Substitution logic for the LM201AN is based on the following electrical and mechanical criteria:

Primary Substitution Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 1
• Slew Rate: 0.5 V/µs (minimum requirement)
• Current - Input Bias: 30 nA (maximum allowable)
• Voltage - Input Offset: 700 µV (maximum allowable)
• Current - Supply: 1.8 mA (maximum allowable)
• Voltage - Supply Span: 10V to 44V (minimum and maximum operating range)
• Operating Temperature: -25°C to 85°C (minimum coverage)

Direct Equivalent (Electrical Match with Package Variation): The LM201ADR2G maintains identical electrical specifications (slew rate, input bias current, input offset voltage, supply current, and supply voltage range) while offering surface-mount packaging in 8-SOIC format. This part is manufactured by onsemi and carries active product status with RoHS3 compliance.

Similar Substitutes (Partial Parameter Match): The LM10CLN/NOPB and LM10CN/NOPB (Texas Instruments) are general-purpose operational amplifiers in 8-DIP through-hole packages. These parts exhibit superior input bias current (12 nA) and lower input offset voltage (500 µV) compared to the LM201AN. However, they operate at reduced supply voltage ranges (1.1V to 6.5V for LM10CLN/NOPB; 1.1V to 40V for LM10CN/NOPB) and narrower operating temperature ranges (0°C to 70°C). These devices are suitable for applications where the LM201AN's supply voltage range exceeds system requirements.

Parameter Comparison

Engineering Selection Recommendations

LM201ADR2G (Direct Electrical Equivalent): The LM201ADR2G is the primary substitute for the LM201AN when electrical specifications must remain unchanged. Both devices share identical slew rate, input bias current, input offset voltage, supply current, and supply voltage range specifications. The LM201ADR2G carries active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. The primary design consideration is the transition from through-hole (8-DIP) to surface-mount (8-SOIC) packaging, which requires PCB layout modification. This substitution is appropriate for new designs or production transitions where surface-mount assembly is feasible.

LM10CLN/NOPB and LM10CN/NOPB (Through-Hole Alternatives): These Texas Instruments devices maintain the 8-DIP through-hole package format, eliminating PCB redesign requirements. Both parts offer superior input bias current (12 nA) and lower input offset voltage (500 µV) specifications. However, the reduced supply voltage range and narrower operating temperature range restrict their application scope. The LM10CLN/NOPB operates from 1.1V to 6.5V, suitable only for low-voltage applications. The LM10CN/NOPB extends the maximum supply voltage to 40V, approaching the LM201AN's 44V maximum but still falling short. Both devices operate only from 0°C to 70°C, excluding the LM201AN's extended lower temperature range (-25°C). These substitutes are appropriate only when application requirements fall within their specified operating ranges and when the superior input characteristics provide measurable system benefits.

Frequently Asked Questions (FAQ)

Q: Can the LM201ADR2G directly replace the LM201AN in existing PCB designs?

A: The LM201ADR2G provides electrical equivalence but requires PCB layout modification. The LM201AN uses 8-DIP through-hole packaging (0.300" width), while the LM201ADR2G uses 8-SOIC surface-mount packaging (0.154" width). Pin-to-pin electrical functionality is identical, but physical placement and soldering methods differ. Existing through-hole PCB designs cannot accommodate the LM201ADR2G without redesign.

Q: What are the key differences between the LM201AN and LM10 series devices?

A: The LM201AN and LM10 series (LM10CLN/NOPB, LM10CN/NOPB) are both general-purpose operational amplifiers with single-circuit configurations in 8-DIP packages. The LM201AN operates from 10V to 44V supply voltage, while LM10 devices operate from 1.1V minimum. The LM10 series exhibits superior input bias current (12 nA versus 30 nA) and lower input offset voltage (500 µV versus 700 µV). The LM201AN supports extended temperature operation (-25°C to 85°C) compared to LM10 devices (0°C to 70°C). Supply current consumption differs: LM201AN draws 1.8 mA, while LM10CLN/NOPB draws 280 µA and LM10CN/NOPB draws 300 µA.

Q: Is the LM201AN suitable for new product designs?

A: The LM201AN carries obsolete product status. While 1,678 units remain in inventory, long-term availability is not assured. New product designs should specify the LM201ADR2G (active status, surface-mount) or evaluate LM10 series alternatives if application requirements permit reduced supply voltage ranges and narrower operating temperatures.

Q: What compliance certifications apply to substitute parts?

A: The LM201AN is RoHS non-compliant. The LM201ADR2G, LM10CLN/NOPB, and LM10CN/NOPB all carry ROHS3 compliance certification. All four devices are REACH Unaffected and classified under ECCN EAR99. Regulatory requirements may mandate substitution to compliant alternatives regardless of electrical equivalence.

Q: Can the LM10 series operate at the LM201AN's maximum supply voltage of 44V?

A: The LM10CN/NOPB supports supply voltages up to 40V, falling 4V short of the LM201AN's 44V maximum. The LM10CLN/NOPB is limited to 6.5V maximum supply voltage. Applications requiring operation at 40V to 44V supply voltage cannot use LM10CLN/NOPB and must use either the LM201AN, LM201ADR2G, or LM10CN/NOPB with design margin verification.

Q: What is the impact of slew rate differences between the LM201AN and LM10 series?

A: The LM201AN specifies 0.5 V/µs slew rate. The LM10 series devices do not provide slew rate specifications in the available data. Slew rate determines the maximum rate of output voltage change and affects high-frequency performance. Applications sensitive to slew rate performance should not substitute LM10 devices without independent verification of slew rate characteristics.
