Substitute Part Grouping Explanation

Substitution eligibility for the LM95214CISDX is determined by strict equivalence across the following critical parameters:

• Sensor Type: Digital, Local/Remote configuration
• Temperature Sensing Range: -40°C to 125°C (local and remote)
• Output Interface: SMBus protocol
• Supply Voltage: 3V to 3.6V
• Resolution: 10-bit
• Accuracy: ±2°C
• Package: 14-WFDFN Exposed Pad (14-WSON 4x4)
• Mounting: Surface Mount

The LM95214CISDX/NOPB qualifies as a direct substitute based on complete parameter alignment across all electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The LM95214CISDX/NOPB is the direct functional equivalent for the obsolete LM95214CISDX. Both parts maintain identical electrical specifications, temperature ranges, resolution, accuracy, and SMBus interface characteristics. The substitute part is currently in active production status, ensuring procurement availability and supply chain continuity.

The primary distinction between the two parts is regulatory compliance status. The LM95214CISDX/NOPB carries ROHS3 compliance certification, whereas the original part is RoHS non-compliant. For applications subject to RoHS directives or environmental regulations, the LM95214CISDX/NOPB is the appropriate selection. Both parts maintain identical MSL ratings and REACH status.

Pin-to-pin compatibility and functional equivalence are confirmed across all operating parameters, making the LM95214CISDX/NOPB suitable for direct replacement in existing designs without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the LM95214CISDX/NOPB replace the LM95214CISDX in existing designs?

A: Yes. The LM95214CISDX/NOPB is pin-to-pin compatible and functionally equivalent. All electrical specifications, temperature ranges, resolution, accuracy, and interface protocols are identical. No circuit redesign is required.

Q: What is the primary reason to transition from LM95214CISDX to LM95214CISDX/NOPB?

A: The original LM95214CISDX is obsolete and no longer in production. The LM95214CISDX/NOPB is the active production equivalent with identical functionality and improved regulatory compliance (ROHS3).

Q: Are there package differences between these parts?

A: No. Both parts use the 14-WFDFN Exposed Pad package (14-WSON 4x4) with surface mount configuration. PCB footprints are identical.

Q: What is the difference in RoHS compliance?

A: The LM95214CISDX is RoHS non-compliant. The LM95214CISDX/NOPB is ROHS3 compliant. For applications requiring RoHS certification or operating in regulated markets, the LM95214CISDX/NOPB is the required selection.

Q: Are the temperature sensing ranges identical?

A: Yes. Both parts provide identical local and remote temperature sensing from -40°C to 125°C with 10-bit resolution and ±2°C accuracy across the full operating range of -40°C to 140°C.

Q: Is the SMBus interface protocol identical?

A: Yes. Both parts implement identical SMBus output interface with the same feature set: One-Shot mode, Output Switch, Programmable Limit, Shutdown Mode, and Standby Mode.

Q: What is the supply voltage requirement?

A: Both parts require 3V to 3.6V supply voltage. Ensure power supply design maintains this range for proper operation.
