Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM201AD is determined by electrical and mechanical parameter equivalence within the general-purpose operational amplifier category. The critical parameters governing substitution are:

Electrical Parameters:

• Slew Rate: 0.5 V/µs
• Gain Bandwidth Product: 1 MHz
• Voltage - Input Offset: 700 µV
• Voltage - Supply Span: 10 V to 44 V
• Operating Temperature Range: -40°C to 105°C

Mechanical Parameters:

• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Number of Circuits: 1

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts must maintain identical or superior electrical performance within these specified ranges and utilize the same 8-SOIC package footprint to ensure direct board-level compatibility.

Engineering Selection Recommendations

LM201ADT (STMicroelectronics)

The LM201ADT is the direct equivalent substitute for the obsolete LM201AD. Both components are manufactured by STMicroelectronics and share identical electrical specifications and operating temperature range (-40°C to 105°C). The LM201ADT maintains active product status with substantial inventory availability (271,704 pieces). This component is the primary selection for direct replacement applications requiring no design modification.

LM201AVDR2G (onsemi)

The LM201AVDR2G is manufactured by onsemi and provides functional equivalence with identical electrical performance and operating temperature range (-40°C to 105°C). This component maintains active product status with high inventory availability (355,300 pieces). The LM201AVDR2G is suitable for applications where onsemi component sourcing is preferred or required.

LM201ADR2G (onsemi)

The LM201ADR2G is manufactured by onsemi and provides functional equivalence with identical electrical specifications. This component operates within a reduced temperature range (-25°C to 85°C) compared to the LM201AD. The LM201ADR2G is suitable for applications operating within this narrower temperature specification. This component maintains active product status with inventory availability (25,300 pieces).

All substitute components are ROHS3 compliant, possess MSL rating of 1 (Unlimited), and utilize the identical 8-SOIC surface mount package footprint.

Frequently Asked Questions (FAQ)

Q: Can the LM201ADT directly replace the LM201AD without circuit modification?

A: Yes. The LM201ADT is manufactured by the same supplier (STMicroelectronics) and maintains identical electrical specifications, operating temperature range, and 8-SOIC package footprint. Direct substitution is supported at the board level.

Q: What is the primary difference between LM201ADR2G and LM201AVDR2G?

A: Both components are manufactured by onsemi and share identical electrical specifications and 8-SOIC packaging. The primary difference is operating temperature range: LM201ADR2G operates from -25°C to 85°C, while LM201AVDR2G operates from -40°C to 105°C. Component selection depends on application temperature requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The LM201AD and all listed substitute components (LM201ADT, LM201ADR2G, LM201AVDR2G) are ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: What is the significance of the 8-SOIC package specification?

A: The 8-SOIC (0.154", 3.90mm Width) package is a surface mount package with standardized pin configuration and footprint. All substitute components utilize this identical package, ensuring mechanical and electrical compatibility on printed circuit boards designed for the LM201AD.

Q: Can onsemi components be substituted for STMicroelectronics components in existing designs?

A: Yes, provided the application operating temperature range does not exceed the onsemi component specification. LM201AVDR2G (-40°C to 105°C) matches the LM201AD temperature range. LM201ADR2G (-25°C to 85°C) is suitable only for applications operating within this narrower range.

Q: What is the input bias current difference between STMicroelectronics and onsemi versions?

A: The LM201AD and LM201ADT (STMicroelectronics) specify 25 nA input bias current. The LM201ADR2G and LM201AVDR2G (onsemi) specify 30 nA input bias current. This 5 nA difference is within typical operational amplifier tolerance and does not affect functional equivalence for general-purpose applications.

Q: Are packaging options (Cut Tape vs. Tape & Reel) interchangeable?

A: Yes. Cut Tape (CT) and Tape & Reel (TR) packaging options contain identical components with different delivery formats. Selection depends on procurement and assembly process requirements, not electrical or mechanical compatibility.
