LM95231CIMM-2 Equivalent & Substitute Parts
Part Overview
The LM95231CIMM-2 is a digital temperature sensor from Texas Instruments' TruTherm™ series, designed for local and remote temperature monitoring applications. It provides 9-bit local and 12-bit remote temperature resolution across a 0°C to 85°C sensing range with SMBus output interface. The device operates from a 3V to 3.6V supply and features programmable resolution, one-shot capability, and shutdown modes for power management.
The LM95231CIMM-2 carries an Obsolete product status, making it necessary to identify functionally equivalent alternatives for new designs and ongoing production requirements. The substitute part LM95231CIMM-2/NOPB maintains identical electrical and mechanical specifications while offering Active product status and improved compliance certifications.

Substitute Part Grouping Explanation
The LM95231CIMM-2/NOPB qualifies as a direct substitute based on the following criteria:
Electrical Parameter Equivalence:
- Identical sensor type (Digital, Local/Remote)
- Matching temperature sensing range (0°C ~ 85°C for both local and remote channels)
- Identical resolution specifications (9 b Local, 12 b Remote)
- Same output interface (SMBus)
- Identical supply voltage range (3V ~ 3.6V)
- Matching accuracy specification (±3°C)
- Same operating temperature range (0°C ~ 125°C)
Mechanical Parameter Equivalence:
- Identical package type (8-VSSOP)
- Same case dimensions (8-TSSOP, 8-MSOP with 0.118", 3.00mm Width)
- Same mounting type (Surface Mount)
Feature Equivalence:
- Identical feature set (One-Shot, Programmable Resolution, Shutdown Mode, Standby Mode)
The primary distinction between these parts is product status and compliance certification, not functional or physical characteristics.
