AT30TS00-MAH-T Equivalent & Substitute Parts

Part Overview

The AT30TS00-MAH-T is an internal temperature sensor manufactured by Microchip Technology, designed for local temperature monitoring applications. This device operates across a -20°C to 125°C sensing range with 11-bit resolution and communicates via 2-Wire Serial I2C/SMBus protocol. The component is actively produced and maintains full RoHS3 compliance. Substitute parts are identified when equivalent functional performance can be achieved within the specified electrical and mechanical parameters while maintaining compatibility with the host system interface requirements.

Substitute Part Grouping Explanation

The CAT34TS02VP2GT4C from onsemi qualifies as a substitute based on the following alignment criteria:

Compatible Parameters:

• I2C/SMBus communication protocol compatibility
• Local temperature sensing within the -20°C to 125°C range
• Surface mount 8-pin package format (8-TDFN 2x3)
• Active product status with current manufacturing
• RoHS3 compliance certification

Functional Equivalence Basis: Both devices operate as local temperature sensors with I2C/SMBus interfaces suitable for thermal monitoring applications. The substitute maintains the same communication protocol and package footprint, enabling direct replacement in compatible circuit designs.

Parameter Comparison

Engineering Selection Recommendations

Both the AT30TS00-MAH-T and CAT34TS02VP2GT4C maintain active product status with full RoHS3 compliance and REACH unaffected certification. The CAT34TS02VP2GT4C offers enhanced resolution at 12 bits compared to the 11-bit resolution of the AT30TS00-MAH-T, and provides a wider operating temperature range extending to -45°C and 130°C. The substitute device features improved moisture sensitivity classification (MSL 1 versus MSL 3), indicating superior handling characteristics during storage and assembly.

Supply voltage specification differs: the AT30TS00-MAH-T accepts 2.7V to 3.6V while the CAT34TS02VP2GT4C operates at 3.3V. System designs must confirm that 3.3V supply voltage is available and compatible with the host circuit topology.

Both devices employ I2C/SMBus communication protocols and 8-pin surface mount packages with identical footprint dimensions (2x3mm), supporting direct PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the CAT34TS02VP2GT4C replace the AT30TS00-MAH-T in existing designs?

A: Direct replacement is possible when the host system operates at 3.3V supply voltage. The I2C/SMBus interface and 8-TDFN package footprint are compatible. Firmware or software must accommodate the 12-bit resolution output of the substitute device.

Q: What are the key differences in electrical specifications?

A: The primary differences are supply voltage (2.7V-3.6V versus 3.3V), resolution (11 bits versus 12 bits), and operating temperature range (-40°C to 125°C versus -45°C to 130°C). The CAT34TS02VP2GT4C also features superior moisture sensitivity classification.

Q: Are the package dimensions identical?

A: Both devices use 8-pin packages with 2x3mm dimensions. The AT30TS00-MAH-T uses 8-WDFN format while the CAT34TS02VP2GT4C uses 8-TDFN format. Both include exposed pads and are compatible with standard surface mount assembly processes.

Q: What compliance certifications apply to both parts?

A: Both devices are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 for export purposes.

Q: Does the higher resolution of the substitute affect compatibility?

A: The 12-bit resolution of the CAT34TS02VP2GT4C provides finer temperature measurement granularity than the 11-bit AT30TS00-MAH-T. System firmware must be configured to interpret the additional resolution bits. This enhancement does not prevent substitution but requires software validation.
