LM95235DIMM Temperature Sensor Equivalent & Substitute Parts

Part Overview

The LM95235DIMM is a digital temperature sensor manufactured by Texas Instruments, designed for local and remote temperature monitoring across -40°C to 90°C. This part operates via SMBus interface with 10-bit resolution and 3V to 3.6V supply voltage. The LM95235DIMM is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain compatibility with SMBus communication protocol, matching package dimensions (8-VSSOP), and operating within the specified temperature and voltage parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LM95235DIMM are selected based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Output Type: SMBus or I2C/SMBus compatible
• Package / Case: 8-TSSOP or 8-MSOP (0.118", 3.00mm Width)
• Sensor Type: Digital, Local/Remote
• Voltage - Supply: 3V minimum to 3.6V maximum overlap
• Resolution: 10-bit or higher
• Mounting Type: Surface Mount

Substitute Categories:

Direct Replacement (Active Status): LM95235DIMM/NOPB maintains identical electrical and mechanical specifications with active product status and improved remote resolution (12-bit).

Compatible Alternatives (Active Status): ADM1032ARMZ-REEL, ADT7461AARMZ-R, SA56004ADP,118, SA56004CDP,118, and SA56004EDP,118 meet core functional requirements with SMBus/I2C compatibility and matching package footprints. These parts operate within overlapping voltage and temperature ranges with comparable accuracy specifications.

Parameter Comparison

Engineering Selection Recommendations

LM95235DIMM/NOPB is the primary substitute, offering identical electrical specifications with active product status. This part is manufactured by National Semiconductor and provides improved remote temperature resolution (12-bit) while maintaining 10-bit local resolution. Selection of this part eliminates obsolescence risk and ensures long-term availability.

ADT7461AARMZ-R (onsemi) provides enhanced accuracy (±1°C highest) and extended remote temperature sensing range (-64°C ~ 191°C). This part is ROHS3 compliant and suitable for applications requiring superior accuracy performance. Resolution is reduced to 8-bit, which may impact applications requiring 10-bit precision.

SA56004ADP,118, SA56004CDP,118, and SA56004EDP,118 (NXP USA Inc.) maintain 10-bit resolution and are ROHS3 compliant with active product status. These parts support extended supply voltage range (3V ~ 5.5V) and extended local/remote temperature range (-40°C ~ 125°C). Packaging variants differ: SA56004ADP,118 and SA56004CDP,118 are supplied on tape and reel, while SA56004EDP,118 is supplied on cut tape with Digi-Reel.

ADM1032ARMZ-REEL (Analog Devices Inc.) is an active product with SMBus compatibility and high inventory availability. Detailed electrical specifications are not provided in the reference data; verification of compatibility parameters is required before selection.

Frequently Asked Questions (FAQ)

Q: Can LM95235DIMM be directly replaced with LM95235DIMM/NOPB?

A: Yes. LM95235DIMM/NOPB is a direct substitute with identical local temperature sensing range (-40°C ~ 90°C), SMBus output, 10-bit local resolution, and 3V ~ 3.6V supply voltage. The primary difference is improved remote resolution (12-bit vs. 10-bit) and active product status. Pin-for-pin compatibility and package footprint are identical (8-VSSOP).

Q: What is the key difference between SA56004 variants (ADP, CDP, EDP)?

A: All three SA56004 variants (SA56004ADP,118, SA56004CDP,118, SA56004EDP,118) share identical electrical specifications. The differences are packaging and supply format: ADP and CDP are supplied on tape and reel (TR), while EDP is supplied on cut tape (CT) with Digi-Reel. Selection depends on assembly process requirements and inventory management preferences.

Q: Does ADT7461AARMZ-R maintain 10-bit resolution like the LM95235DIMM?

A: No. ADT7461AARMZ-R operates at 8-bit resolution, which is lower than the LM95235DIMM's 10-bit resolution. However, ADT7461AARMZ-R provides superior accuracy (±1°C highest vs. ±2°C) and extended remote temperature range (-64°C ~ 191°C). Selection should be based on application requirements for resolution versus accuracy trade-offs.

Q: Are all substitute parts RoHS compliant?

A: No. The original LM95235DIMM is RoHS non-compliant. Among active substitutes, ADT7461AARMZ-R and all SA56004 variants (ADP, CDP, EDP) are ROHS3 compliant. LM95235DIMM/NOPB RoHS status is not specified in the reference data. Compliance verification is required for applications with RoHS requirements.

Q: Can substitute parts operate at the same 3V ~ 3.6V supply voltage as LM95235DIMM?

A: Yes. All substitute parts support minimum 3V supply voltage. LM95235DIMM/NOPB, ADT7461AARMZ-R, and ADM1032ARMZ-REEL are specified for 3V ~ 3.6V operation. SA56004 variants support extended range (3V ~ 5.5V), which includes the 3V ~ 3.6V window. Supply voltage compatibility is maintained across all substitutes.

Q: What is the package footprint compatibility for PCB redesign?

A: All substitute parts use 8-TSSOP or 8-MSOP packages with 0.118" (3.00mm) width, matching the LM95235DIMM footprint. Surface mount mounting type is identical. PCB layout modifications are not required for package compatibility. Pin assignment verification is recommended before assembly.
