LM95235DIMMX Equivalent & Substitute Parts

Part Overview

The LM95235DIMMX is a digital temperature sensor manufactured by Texas Instruments, designed for local and remote temperature monitoring across a -40°C to 90°C sensing range. This component operates via SMBus interface with 10-bit resolution and is housed in an 8-VSSOP package. The part is currently listed as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM95235DIMMX is determined by the following critical parameters:

• Sensor Type: Must support Digital, Local/Remote temperature monitoring
• Output Interface: Must utilize SMBus protocol for system compatibility
• Supply Voltage: Must operate within 3V ~ 3.6V range
• Package Compatibility: Must use 8-TSSOP or 8-MSOP form factor (0.118", 3.00mm Width)
• Mounting Type: Must be Surface Mount
• Temperature Sensing Range: Local and remote sensing capabilities must cover or exceed the application requirements

Substitute parts are grouped into two categories:

Direct Equivalent (Pin-Compatible, Same Series): LM95235DIMMX/NOPB maintains identical electrical specifications and packaging, differing only in product status (Active vs. Obsolete) and RoHS compliance level.

Functional Equivalent (Cross-Manufacturer): ADM1032ARMZ-REEL and ADT7461AARMZ-R provide equivalent functionality through SMBus interface and compatible packaging, though with variations in resolution, temperature range, and accuracy specifications.

Parameter Comparison

Engineering Selection Recommendations

LM95235DIMMX/NOPB is the primary substitute for the obsolete LM95235DIMMX. This part maintains identical electrical and mechanical specifications while offering Active product status and ROHS3 compliance. Selection of this part eliminates obsolescence risk and ensures regulatory compliance for new designs and production runs.

ADT7461AARMZ-R (onsemi) serves as a functional cross-manufacturer alternative. This part provides superior accuracy (±1°C highest vs. ±2°C) and extended remote temperature sensing range (-64°C ~ 191°C vs. -40°C ~ 90°C). The trade-off is reduced resolution (8 bits vs. 10 bits). This substitute is suitable for applications where extended temperature monitoring range and improved accuracy are prioritized over resolution. ROHS3 compliance and Active status support long-term availability.

ADM1032ARMZ-REEL (Analog Devices Inc.) is listed as a manufacturer-recommended alternative. Limited specification data is provided in the reference material. Detailed datasheet review is required to confirm compatibility with specific application requirements before implementation.

Frequently Asked Questions (FAQ)

Q: Can LM95235DIMMX/NOPB be used as a direct replacement for LM95235DIMMX?

A: Yes. LM95235DIMMX/NOPB is electrically and mechanically identical to the obsolete LM95235DIMMX. The primary differences are product status (Active vs. Obsolete) and RoHS compliance level (ROHS3 vs. non-compliant). No circuit modifications are required.

Q: What are the key differences between LM95235DIMMX and ADT7461AARMZ-R?

A: Both parts share SMBus interface, 3V ~ 3.6V supply voltage, and 8-TSSOP/8-MSOP packaging. ADT7461AARMZ-R offers improved accuracy (±1°C vs. ±2°C at best case) and extended remote temperature range (-64°C ~ 191°C vs. -40°C ~ 90°C). The LM95235DIMMX provides higher resolution (10 bits vs. 8 bits). Selection depends on whether resolution or extended temperature range is more critical to the application.

Q: Is the 8-VSSOP package equivalent to 8-TSSOP or 8-MSOP?

A: The LM95235DIMMX is supplied in 8-VSSOP package format. Substitute parts ADT7461AARMZ-R and ADM1032ARMZ-REEL use 8-TSSOP and 8-MSOP packages. These are functionally equivalent surface-mount packages with identical 0.118" (3.00mm) width. PCB layout compatibility should be verified for specific applications.

Q: Why is LM95235DIMMX marked as obsolete?

A: Product obsolescence is determined by the manufacturer. LM95235DIMMX/NOPB, the active variant of the same base product (LM95235), remains in production and is the recommended path for new designs and ongoing supply.

Q: Are all substitute parts RoHS3 compliant?

A: LM95235DIMMX/NOPB and ADT7461AARMZ-R are both ROHS3 compliant. ADM1032ARMZ-REEL compliance status is not specified in the provided reference data. Verification with the manufacturer is recommended if RoHS compliance is a design requirement.

Q: What is the inventory status of these parts?

A: LM95235DIMMX/NOPB has 764 units in stock. ADT7461AARMZ-R has 6160 units available. ADM1032ARMZ-REEL has 25077 units in stock. Inventory levels are subject to change and should be confirmed at time of procurement.
