LM211DR2 Equivalent & Substitute Parts

Part Overview

The LM211DR2 is a single comparator integrated circuit manufactured by onsemi, housed in an 8-SOIC surface mount package. This device functions as a high-voltage comparator suitable for general-purpose applications requiring voltage comparison and signal conditioning. The LM211DR2 is classified as obsolete, making identification of compatible substitute parts essential for ongoing design support, production continuity, and system maintenance. Equivalent parts must maintain functional compatibility across electrical specifications, package dimensions, and operational parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM211DR2 is determined by the following critical parameters:

• Package Compatibility: Both main and substitute parts must use 8-SOIC surface mount packaging with identical physical dimensions (0.154", 3.90mm Width)
• Functional Classification: All parts must operate as single-element comparators with general-purpose application capability
• Supply Voltage Range: Substitute parts must support the operating voltage specifications of 5V ~ 30V (single supply) or ±2.5V ~ 15V (dual supply)
• Output Configuration: Substitute parts must provide compatible output types including DTL, MOS, Open-Collector, Open-Emitter, RTL, or TTL configurations
• Operating Temperature Range: Substitute parts must maintain operation across -25°C ~ 85°C
• Electrical Characteristics: Input offset voltage, input bias current, quiescent current, and other specified parameters must remain within acceptable tolerances for the application

The LM211DR2G is identified as a direct substitute based on identical package type, matching functional classification, and equivalent electrical operating parameters.

Engineering Selection Recommendations

The LM211DR2G is the primary substitute for the obsolete LM211DR2. Both devices share identical 8-SOIC packaging, single-element comparator architecture, and moisture sensitivity classification. The LM211DR2G offers the advantage of active product status, ensuring continued availability and manufacturing support. Additionally, the LM211DR2G achieves ROHS3 compliance, providing environmental and regulatory advantages over the non-compliant LM211DR2.

For applications requiring strict compliance with legacy specifications or non-compliant material requirements, the LM211DR2 remains available in current inventory. However, for new designs or production transitions, the LM211DR2G is the recommended selection due to its active status and enhanced regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the LM211DR2G directly replace the LM211DR2 in existing designs?

A: Yes. Both devices use identical 8-SOIC packaging and share the same single-element comparator functional classification. Pin configuration and electrical operating parameters are compatible for direct substitution in surface mount applications.

Q: What is the primary difference between LM211DR2 and LM211DR2G?
