LM56BIMMX Temperature Sensor Equivalent & Substitute Parts

Part Overview

The LM56BIMMX 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 LM56BIMMX is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM56BIMMX is determined by strict equivalence across the following parameters:

• Sensor type classification (Analog, Local)
• Temperature sensing range (-40°C ~ 125°C)
• Output type (Analog Voltage)
• Resolution (6.2mV/°C)
• Supply voltage range (2.7V ~ 10V)
• Accuracy specifications (±2°C / ±3°C)
• Package and mounting compatibility (8-VSSOP surface mount)
• Functional features (Output Switch)

The LM56BIMMX/NOPB qualifies as a direct substitute based on complete parameter alignment across all electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The LM56BIMMX/NOPB is the direct active equivalent for the obsolete LM56BIMMX. Both parts maintain identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility. The primary distinction is product status and regulatory compliance: the LM56BIMMX/NOPB is actively manufactured and ROHS3 compliant, whereas the original LM56BIMMX is obsolete and RoHS non-compliant. For new designs and production continuity, the LM56BIMMX/NOPB is the appropriate selection. Both parts share identical moisture sensitivity levels, REACH status, and trade classification codes, confirming full substitutability.

Frequently Asked Questions (FAQ)

Q: Can the LM56BIMMX/NOPB replace the LM56BIMMX in existing designs?

A: Yes. The LM56BIMMX/NOPB is electrically and mechanically identical to the LM56BIMMX. Both parts feature the same temperature range (-40°C ~ 125°C), output resolution (6.2mV/°C), supply voltage (2.7V ~ 10V), accuracy specifications (±2°C / ±3°C), and 8-VSSOP package configuration. No circuit modifications are required.

Q: What is the significance of the "/NOPB" suffix?

A: The "/NOPB" designation indicates lead-free, RoHS3 compliant packaging. This reflects the regulatory compliance status of the part, not a functional difference. The electrical and thermal performance remain unchanged.

Q: Are there any compliance differences between these parts?

A: The LM56BIMMX/NOPB is ROHS3 compliant, while the original LM56BIMMX is RoHS non-compliant. Both maintain REACH Unaffected status and identical ECCN and HTSUS classifications. For applications requiring RoHS compliance, the LM56BIMMX/NOPB is the required selection.

Q: Is the package footprint identical between both parts?

A: Yes. Both the LM56BIMMX and LM56BIMMX/NOPB use the 8-VSSOP package (8-TSSOP, 8-MSOP variant) with 0.118" / 3.00mm width. PCB layouts and assembly processes require no modification.

Q: What is the moisture sensitivity level for these parts?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. Standard component storage practices apply.
