LM95214CISD Temperature Sensor - Equivalent & Substitute Parts

Part Overview

The LM95214CISD is a digital temperature sensor manufactured by Texas Instruments, designed for local and remote temperature monitoring applications. It operates across a -40°C to 125°C sensing range with 10-bit resolution and communicates via SMBus interface. The device is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system support, design updates, and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM95214CISD is determined by strict equivalence across the following critical parameters:

• Sensor type classification (Digital, Local/Remote)
• Sensing temperature range (-40°C ~ 125°C minimum)
• Output interface protocol (SMBus)
• Supply voltage specification (3V ~ 3.6V)
• Resolution (10-bit)
• Accuracy specification (±2°C)
• Package and pinout compatibility (14-WFDFN Exposed Pad)
• Mounting technology (Surface Mount)

The LM95214CISD/NOPB qualifies as a direct substitute based on identical electrical specifications, sensor functionality, and physical packaging. The primary distinction lies in packaging format and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The LM95214CISD/NOPB serves as the direct functional equivalent to the LM95214CISD. Both devices are classified as obsolete products with identical electrical and mechanical specifications. The primary differentiator is regulatory compliance status: the LM95214CISD/NOPB achieves ROHS3 compliance, whereas the original LM95214CISD does not. For new designs or systems requiring RoHS compliance certification, the LM95214CISD/NOPB is the appropriate selection. For legacy system maintenance where RoHS compliance is not mandated, either part number is electrically and functionally interchangeable. Packaging format differences (Cut Tape and Digi-Reel options for the /NOPB variant) may influence procurement logistics but do not affect circuit-level performance.

Frequently Asked Questions (FAQ)

Q: Are the LM95214CISD and LM95214CISD/NOPB pin-compatible?

A: Yes. Both devices use the 14-WFDFN Exposed Pad package with identical pinout and electrical characteristics. Direct PCB substitution is possible without circuit modification.

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

A: The "/NOPB" designation indicates the part is supplied in Cut Tape and Digi-Reel packaging formats without lead (Pb) and meets ROHS3 compliance requirements. The core device functionality remains identical to the base part number.

Q: Can the LM95214CISD/NOPB be used in applications originally designed for the LM95214CISD?

A: Yes. The LM95214CISD/NOPB is a direct substitute. All electrical specifications, sensor performance, communication protocol, and package dimensions are identical. The improved RoHS compliance status of the /NOPB variant makes it suitable for both legacy and new applications.

Q: Are there any supply voltage or temperature range differences between these parts?

A: No. Both parts operate at 3V to 3.6V supply voltage, sense temperatures from -40°C to 125°C, and maintain ±2°C accuracy across the specified range. Operating temperature extends to -40°C to 140°C for both variants.

Q: What should be considered when selecting between these two part numbers?

A: Selection should be based on regulatory requirements and packaging preferences. If RoHS3 compliance is required, specify the LM95214CISD/NOPB. If procurement requires specific packaging formats (Cut Tape or Digi-Reel), the /NOPB variant offers these options. For applications without compliance mandates, either part number delivers identical performance.
