LM56BIM Temperature Sensor - Equivalent & Substitute Parts
Part Overview
The LM56BIM is an analog temperature sensor manufactured by Texas Instruments, designed for local temperature measurement across the -40°C to 125°C range. This component operates with a supply voltage of 2.7V to 10V and provides analog voltage output with 6.2mV/°C resolution. The LM56BIM is classified as "Not For New Designs," indicating it has been superseded in Texas Instruments' product portfolio. Finding equivalent or substitute parts is necessary for legacy system maintenance, repair operations, and applications where continued supply of the original component is uncertain.

Substitute Part Grouping Explanation
Substitution of the LM56BIM is determined by strict equivalence across the following critical parameters:
- Sensor Type & Measurement Capability: Analog, local temperature sensing only
- Temperature Range: -40°C to 125°C operational window
- Output Characteristics: Analog voltage output with 6.2mV/°C resolution
- Supply Voltage Compatibility: 2.7V to 10V input range
- Accuracy Specification: ±2°C to ±3°C across the operating range
- Package & Pinout: 8-SOIC surface mount package with identical mechanical dimensions
- Functional Features: Output switch capability
The LM56BIM/NOPB qualifies as a direct substitute based on identical electrical specifications, mechanical compatibility, and functional equivalence across all critical parameters.

Engineering Selection Recommendations
The LM56BIM/NOPB serves as a direct electrical and mechanical substitute for the LM56BIM. Both components are classified as legacy products (Not For New Designs and Obsolete, respectively), indicating limited future availability through standard distribution channels.
The primary distinction between these parts is regulatory compliance: the LM56BIM/NOPB achieves ROHS3 compliance, whereas the original LM56BIM is RoHS non-compliant. For applications subject to RoHS requirements or environmental regulations, the LM56BIM/NOPB is the appropriate selection. For legacy systems with no compliance mandates, either part functions identically.
Both components carry identical electrical performance, temperature measurement range, output characteristics, and package specifications. Selection between them should be based on regulatory requirements and component availability rather than functional differences.
Frequently Asked Questions (FAQ)
Q: Can the LM56BIM/NOPB be used as a direct replacement for the LM56BIM?
A: Yes. Both components are electrically and mechanically identical. They share the same sensor type, temperature range (-40°C to 125°C), output type (analog voltage), supply voltage (2.7V to 10V), resolution (6.2mV/°C), accuracy (±2°C to ±3°C), and 8-SOIC package. No circuit modifications are required.
Q: What is the difference between LM56BIM and LM56BIM/NOPB?
A: The primary difference is RoHS compliance status. The LM56BIM/NOPB is ROHS3 compliant, while the LM56BIM is RoHS non-compliant. Electrically and functionally, both parts are identical.
Q: Are these parts suitable for new designs?
A: No. Both the LM56BIM and LM56BIM/NOPB are classified as legacy products. The LM56BIM is marked "Not For New Designs," and the LM56BIM/NOPB is marked "Obsolete." For new applications, consult Texas Instruments' current temperature sensor portfolio for active alternatives.
Q: What is the 8-SOIC package specification?
A: The 8-SOIC (Small Outline Integrated Circuit) package has a width of 0.154 inches (3.90mm). This is a surface mount package with eight pins. Both substitute parts use identical package dimensions and pinout.
Q: What supply voltage range does this sensor require?
A: The LM56BIM and LM56BIM/NOPB both operate with a supply voltage range of 2.7V to 10V. Ensure your circuit provides voltage within this specification.
Q: What is the temperature measurement accuracy?
A: Accuracy is ±2°C across the 25°C to 85°C test condition range, and ±3°C across the full -40°C to 125°C operating range.
