MAX6632MUT-T Equivalent & Substitute Parts

Part Overview

The MAX6632MUT-T is a digital temperature sensor manufactured by Analog Devices Inc./Maxim Integrated, designed for local temperature measurement across a -55°C to 125°C range with 12-bit resolution. The device operates via SPI interface and is packaged in SOT-23-6 surface mount configuration. This part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX6632MUT-T is determined by the following critical parameters:

• Sensor type classification (Digital, Local)
• SPI interface compatibility
• 12-bit resolution requirement
• SOT-23-6 package compatibility
• Supply voltage range overlap (minimum 3V ~ 5.5V support)
• Operating temperature range coverage (-55°C ~ 150°C)
• RoHS3 compliance status

The identified substitute parts, TMP123AIDBVR and TMP123AIDBVT (both Texas Instruments), satisfy these core substitution criteria. Both devices maintain identical sensor type, output interface, resolution, package form factor, and compliance certifications. Variations in local sensing temperature range and accuracy specifications are within acceptable tolerance for equivalent component selection.

Parameter Comparison

Engineering Selection Recommendations

TMP123AIDBVR is the preferred substitute for MAX6632MUT-T applications. This device carries Active product status, ensuring long-term availability and manufacturer support. Both substitute parts maintain full RoHS3 compliance and identical package configuration, enabling direct PCB-level replacement without layout modifications.

TMP123AIDBVT remains functionally equivalent but carries Obsolete product status classification, limiting its suitability for new designs requiring extended component lifecycle assurance.

The local sensing temperature range difference (-40°C minimum versus -55°C minimum) must be evaluated against specific application requirements. Applications operating exclusively within -40°C to 125°C range experience no functional limitation. Applications requiring -55°C operation require design verification against the substitute part's lower temperature boundary.

Frequently Asked Questions (FAQ)

Q: Can TMP123AIDBVR directly replace MAX6632MUT-T in existing designs?

A: Yes. Both devices share identical SPI interface protocol, 12-bit resolution, SOT-23-6 package configuration, and shutdown mode functionality. No firmware or PCB modifications are required for direct substitution within the overlapping operating temperature range (-40°C to 125°C).

Q: What is the temperature range limitation when substituting with TMP123AIDBVR?

A: TMP123AIDBVR operates from -40°C minimum, compared to MAX6632MUT-T's -55°C minimum. Applications requiring temperature measurement below -40°C cannot use this substitute without design modification or alternative component selection.

Q: Are there supply voltage compatibility concerns?

A: TMP123AIDBVR supports 2.7V to 5.5V operation, providing broader low-voltage capability than MAX6632MUT-T (3V minimum). Designs operating at 3V to 5.5V experience no voltage-related compatibility issues.

Q: Why is TMP123AIDBVR preferred over TMP123AIDBVT?

A: TMP123AIDBVR maintains Active product status, guaranteeing manufacturer production continuity and long-term availability. TMP123AIDBVT is classified as Obsolete, presenting future procurement risk similar to the original MAX6632MUT-T.

Q: Do accuracy specifications affect substitution suitability?

A: Accuracy differences exist between devices (MAX6632MUT-T: ±0.8°C versus TMP123AIDBVR: ±1.5°C). Application-specific accuracy requirements must be evaluated independently. Both devices meet 12-bit resolution specification.

Q: Is moisture sensitivity level a concern for substitution?

A: MAX6632MUT-T carries MSL 1 (Unlimited), while TMP123AIDBVR carries MSL 2 (1 Year). Substitute parts require standard moisture control during storage and handling per IPC-A-610 guidelines.
