LM211MDREP Equivalent & Substitute Parts

Part Overview

The LM211MDREP is a general-purpose comparator IC manufactured by Texas Instruments, housed in an 8-SOIC surface-mount package. This device is designed for applications requiring voltage comparison with open-collector, open-emitter, and TTL-compatible output configurations. The part is currently in active production status with robust inventory availability (8231 pcs in stock). Equivalent and substitute parts are identified when they maintain functional compatibility across critical electrical parameters, package specifications, and operational requirements while potentially offering different packaging formats or manufacturer sourcing options.

Substitute Part Grouping Explanation

Substitute parts for the LM211MDREP are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Electrical Compatibility Criteria:

• Comparator type: General Purpose
• Number of elements: 1
• Output type: DTL, MOS, Open-Collector, Open-Emitter, RTL, TTL
• Voltage - Input Offset (Max): 3mV @ ±15V
• Current - Input Bias (Max): 0.1µA @ ±15V
• Current - Quiescent (Max): 6mA

Mechanical Compatibility Criteria:

• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Supplier Device Package: 8-SOIC

Compliance Criteria:

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

The LM211DR2G (onsemi) qualifies as a manufacturer-recommended substitute. While it maintains identical package specifications, electrical characteristics, and compliance certifications, it operates within a narrower supply voltage range (5V ~ 30V, ±2.5V ~ 15V versus 4.6V ~ 30V, ±1.75V ~ 15V) and a reduced operating temperature range (-25°C ~ 85°C versus -55°C ~ 125°C). These differences must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the LM211MDREP and LM211DR2G are active-status products with ROHS3 compliance and MSL Level 1 ratings, making them suitable for production environments with standard moisture handling requirements.

LM211MDREP Selection Criteria:

• Applications requiring extended operating temperature range (-55°C to 125°C)
• Systems operating at supply voltages below 5V or below ±2.5V
• Designs requiring the full specified supply voltage envelope (4.6V minimum single supply)

LM211DR2G Selection Criteria:

• Applications operating within -25°C to 85°C temperature range
• Systems with supply voltages of 5V or higher (single supply) or ±2.5V or higher (dual supply)
• Sourcing flexibility from onsemi manufacturing

Both parts maintain identical electrical performance for input offset voltage, input bias current, and quiescent current specifications. Package and mounting specifications are identical, ensuring direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can LM211DR2G replace LM211MDREP in all applications?

A: LM211DR2G is functionally compatible for applications operating within its specified ranges: supply voltage 5V ~ 30V (single) or ±2.5V ~ 15V (dual), and operating temperature -25°C ~ 85°C. Applications requiring extended temperature operation (-55°C to 125°C) or lower minimum supply voltages (below 5V single or ±2.5V dual) require the LM211MDREP.

Q: Are the package specifications identical?

A: Yes. Both parts use 8-SOIC (0.154", 3.90mm Width) surface-mount packages with identical pinouts and PCB footprints, enabling direct substitution at the board level.

Q: What are the key electrical differences?

A: Input offset voltage, input bias current, and quiescent current specifications are identical. The primary differences are supply voltage operating ranges and temperature ratings, as detailed in the parameter comparison table.

Q: Are both parts RoHS compliant?

A: Yes. Both LM211MDREP and LM211DR2G are ROHS3 compliant with MSL Level 1 moisture sensitivity ratings.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For designs with standard operating conditions (5V or higher supply, -25°C to 85°C operation), either part is acceptable. For designs requiring extended temperature range or lower supply voltages, LM211MDREP is required.
