LM56BIMM Temperature Sensor - Equivalent & Substitute Parts

Part Overview

The LM56BIMM is an analog temperature sensor manufactured by Texas Instruments, designed for local temperature measurement across the -40°C to 125°C range. This component outputs analog voltage proportional to temperature at 6.2mV/°C and operates from a 2.7V to 10V supply. The LM56BIMM is classified as "Not For New Designs," indicating its obsolescence status. Finding equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and field replacement applications.

Key Parameters

Substitute Part Grouping Explanation

The LM56BIMM/NOPB qualifies as a direct substitute based on the following criteria:

• Identical sensor type (Analog, Local)
• Matching temperature sensing range (-40°C ~ 125°C)
• Identical output type (Analog Voltage)
• Matching supply voltage range (2.7V ~ 10V)
• Identical resolution (6.2mV/°C)
• Matching accuracy specifications (±2°C / ±3°C)
• Identical mounting type (Surface Mount)
• Identical package specification (8-VSSOP)
• Identical features (Output Switch)
• Same base product number (LM56)

The primary distinction between these parts is packaging format and compliance status, not electrical or thermal performance.

Parameter Comparison

Engineering Selection Recommendations

The LM56BIMM/NOPB is electrically and mechanically equivalent to the LM56BIMM. Selection between these parts should be based on compliance and supply requirements:

• The LM56BIMM/NOPB offers ROHS3 compliance and REACH unaffected status, making it suitable for applications with regulatory compliance requirements.
• The LM56BIMM/NOPB is available in Cut Tape and Digi-Reel packaging formats, which may align with specific procurement and assembly workflows.
• Both parts share identical electrical performance, thermal range, and package dimensions, ensuring direct functional interchangeability in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can LM56BIMM/NOPB replace LM56BIMM in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The LM56BIMM/NOPB provides improved compliance status (ROHS3 compliant, REACH unaffected) while maintaining all electrical specifications, accuracy, and package dimensions.

Q: What is the difference between LM56BIMM and LM56BIMM/NOPB?

A: The primary differences are packaging format (Cut Tape & Digi-Reel vs. standard) and compliance certifications. The LM56BIMM/NOPB is ROHS3 compliant and REACH unaffected, whereas the LM56BIMM is RoHS non-compliant and REACH affected. Electrical and thermal performance are identical.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 8-VSSOP package with identical dimensions (8-TSSOP, 8-MSOP, 0.118" / 3.00mm width). PCB footprints and assembly processes are interchangeable.

Q: What supply voltage range do these sensors support?

A: Both the LM56BIMM and LM56BIMM/NOPB operate from 2.7V to 10V, accommodating single-cell battery applications through standard logic supply voltages.

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 for both parts.
