LM96063CISDX/NOPB Equivalent & Substitute Parts

Part Overview

The LM96063CISDX/NOPB is a fan control and temperature monitoring IC from Texas Instruments, designed for thermal management applications requiring both internal and external temperature sensing. This device integrates a digital temperature sensor with SMBus interface, fan speed control outputs, and alarm functionality in a compact 10-WSON package.

The main part (LM96063CISDX/NOPB) is currently in Active product status with 2929 units in stock. Substitute parts may be required due to supply constraints, packaging preferences, or inventory availability. The LM96063CISD/NOPB variant is available as an alternative, though it carries Obsolete product status.

Substitute Part Grouping Explanation

Substitution between LM96063CISDX/NOPB and LM96063CISD/NOPB is determined by the following criteria:

Identical Parameters:

Base product number (LM96063)
Manufacturer (Texas Instruments)
Package / Case (10-WFDFN Exposed Pad, 10-WSON 3x3)
Sensor type (Internal and External)
Output type (2-Wire SMBus)
Supply voltage (3V ~ 3.6V)
Operating temperature range (-40°C ~ 85°C)
Topology (ADC Sigma Delta, Comparator, Fan Speed Counter, Register Bank)
Output features (Alarm and Fan outputs)
Compliance (ROHS3, REACH Unaffected, MSL 1)

Differing Parameters:

Packaging format (Tape & Reel vs. Cut Tape & Digi-Reel)
Product status (Active vs. Obsolete)
Local temperature accuracy (±3°C vs. ±6°C)
Inventory availability

Both parts share identical electrical specifications, package geometry, and functional capabilities. The primary differences are packaging delivery method and local sensor accuracy specification.

Engineering Selection Recommendations

LM96063CISDX/NOPB is the primary selection for new designs and production orders. This part maintains Active product status with established supply availability and meets all current compliance requirements (ROHS3, REACH Unaffected).

LM96063CISD/NOPB is available as a substitute only when LM96063CISDX/NOPB is unavailable. This part is classified as Obsolete and carries a reduced local temperature accuracy specification (±6°C vs. ±3°C). The substitute is electrically and mechanically compatible but differs in packaging delivery format (Cut Tape & Digi-Reel vs. Tape & Reel). Selection of the substitute should account for the relaxed local accuracy tolerance and obsolete status, which may impact long-term supply continuity.

Both parts maintain identical compliance certifications and MSL ratings, ensuring equivalent reliability and handling requirements.

Frequently Asked Questions (FAQ)

Q: Are LM96063CISDX/NOPB and LM96063CISD/NOPB pin-compatible?

A: Yes. Both parts use the 10-WFDFN Exposed Pad package with identical pinout and electrical interface. They are directly interchangeable at the PCB level.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Tape & Reel (TR) is continuous reel packaging for automated assembly lines. Cut Tape (CT) & Digi-Reel is pre-cut tape supplied on reels, suitable for lower-volume or manual assembly processes. Both formats contain the same component.

Q: Does the accuracy difference affect circuit design?

A: The local temperature accuracy differs: LM96063CISDX/NOPB specifies ±3°C, while LM96063CISD/NOPB specifies ±6°C. Remote sensor accuracy remains ±3°C for both. Design thermal control algorithms should account for the applicable accuracy specification of the selected part.

Q: Why is LM96063CISD/NOPB marked as Obsolete?

A: Obsolete status indicates the part is no longer in active production. LM96063CISDX/NOPB is the current active variant and should be used for new designs to ensure long-term supply availability.

Q: Can I use LM96063CISD/NOPB in a design originally specified for LM96063CISDX/NOPB?

A: Electrical and mechanical compatibility is confirmed. However, the reduced local accuracy specification and obsolete status must be evaluated against design requirements and supply chain strategy.

Q: Are both parts RoHS compliant?

A: Yes. Both LM96063CISDX/NOPB and LM96063CISD/NOPB are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating.
