TMP411BDR Temperature Sensor - Equivalent & Substitute Parts

Part Overview

The TMP411BDR is a digital temperature sensor manufactured by Texas Instruments, designed for local and remote temperature monitoring applications. This Surface Mount device operates across a supply voltage range of 2.7V to 5.5V and provides 11-bit resolution with I2C/SMBus output interface. The part is currently Active in product status and maintains ROHS3 compliance with full REACH unaffected certification. Substitute parts are identified when equivalent functional performance is required due to inventory constraints, design flexibility, or application-specific packaging preferences.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TMP411BDR are qualified based on the following critical parameters that determine functional equivalence:

• Sensor Type: Digital, Local/Remote capability
• Output Interface: I2C or SMBus protocol compatibility
• Sensing Temperature Range: Local range minimum -40°C with remote range extending to -64°C or lower
• Resolution: 8-bit or higher
• Accuracy: ±1°C or ±2.5°C specification
• Supply Voltage: Compatibility with 2.7V to 5.5V or subset thereof
• Mounting Type: Surface Mount configuration
• Product Status: Active status ensuring continued availability
• Compliance: ROHS3 and REACH unaffected certification

The identified substitute parts meet these criteria while potentially differing in packaging format, exact temperature ranges, or resolution specifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status, ensuring continued manufacturing and supply availability. Both TMP411BDR and ADT7461AARMZ-R carry ROHS3 compliance with REACH unaffected certification, meeting regulatory requirements for industrial and commercial applications.

The ADT7461AARMZ-R provides functional substitution with identical remote temperature sensing range (-64°C ~ 191°C) and matching accuracy specifications (±1°C / ±2.5°C). The primary design consideration is the reduced local temperature range (-40°C ~ 120°C versus -40°C ~ 125°C) and lower resolution (8-bit versus 11-bit). Supply voltage compatibility is narrower (3V ~ 3.6V versus 2.7V ~ 5.5V), requiring verification against circuit design parameters. Package format differs (8-MSOP versus 8-SOIC), necessitating PCB layout modification.

The ADM1032ARMZ-REEL is identified as a substitute based on manufacturer recommendation. Detailed electrical and thermal specifications are not provided in available documentation, requiring direct consultation with Analog Devices Inc. for complete parameter verification before design implementation.

Frequently Asked Questions (FAQ)

Q: Can ADT7461AARMZ-R replace TMP411BDR in all applications?

A: ADT7461AARMZ-R is functionally equivalent for local temperature monitoring within -40°C to 120°C and remote monitoring to 191°C. Applications requiring local temperatures above 120°C or operating below 3V supply voltage require design verification. The 8-bit resolution versus 11-bit may impact measurement precision in applications requiring finer temperature discrimination.

Q: What are the packaging differences between TMP411BDR and ADT7461AARMZ-R?

A: TMP411BDR uses 8-SOIC package (0.154" width, 3.90mm). ADT7461AARMZ-R uses 8-MSOP package (0.118" width, 3.00mm). These are different footprints requiring PCB redesign for direct substitution.

Q: Are all substitute parts ROHS3 compliant?

A: TMP411BDR and ADT7461AARMZ-R are confirmed ROHS3 compliant. ADM1032ARMZ-REEL compliance status is not specified in available data.

Q: What is the supply voltage compatibility range for substitution?

A: TMP411BDR operates 2.7V to 5.5V. ADT7461AARMZ-R operates 3V to 3.6V. Designs operating below 3V or above 3.6V cannot use ADT7461AARMZ-R without circuit modification.

Q: How do resolution differences affect sensor selection?

A: TMP411BDR provides 11-bit resolution for finer temperature measurement granularity. ADT7461AARMZ-R provides 8-bit resolution. Applications requiring measurement precision below 0.5°C increments should retain TMP411BDR or verify ADT7461AARMZ-R resolution meets functional requirements.

Q: Is ADM1032ARMZ-REEL a direct substitute?

A: ADM1032ARMZ-REEL is listed as manufacturer-recommended substitute. Complete electrical specifications are not provided. Verification with Analog Devices Inc. documentation is required before design implementation.
