SE97TP,147 Equivalent & Substitute Parts

Part Overview

The SE97TP,147 is a temperature monitoring system sensor designed for DIMM DDR memory applications. Manufactured by NXP Semiconductors, this integrated circuit provides internal temperature sensing with I2C/SMBus serial output, supporting a sensing range of -40°C to 125°C with ±3°C accuracy. The device operates on a 3V to 3.6V supply and includes alarm and fan control outputs.

The SE97TP,147 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this temperature monitoring function.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SE97TP,147 are identified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Sensor Type: Internal temperature sensing capability
• Sensing Temperature Range: -40°C to 125°C minimum coverage
• Output Interface: I2C/SMBus serial communication protocol
• Output Functions: Alarm and fan control outputs
• Supply Voltage: 3V to 3.6V operating range
• Package Type: 8-WFDFN Exposed Pad (8-HWSON 2x3 footprint)
• Mounting: Surface mount configuration
• Compliance: ROHS3 compliant

Two substitute parts meet these criteria: SE97BTP,547 (NXP Semiconductors) and AT30TSE002A-MAH-T (Microchip Technology). Both devices provide equivalent functional performance within the specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

SE97BTP,547 (NXP Semiconductors): This part is the manufacturer-recommended substitute from NXP. It maintains identical electrical specifications and package footprint compatibility with the SE97TP,147. The device is currently in active production status, ensuring long-term availability. Both alarm and fan control outputs are supported. The primary difference is the moisture sensitivity level (MSL 3 versus MSL 1), which requires appropriate handling during storage and assembly. This substitute is the preferred choice for direct replacement in existing designs.

AT30TSE002A-MAH-T (Microchip Technology): This part provides equivalent functional performance with I2C/SMBus interface, alarm output, and compatible package footprint. The sensing temperature range (-20°C to 125°C) covers the lower bound of the original specification. Accuracy specifications are ±3°C across the full operating range, matching the SE97TP,147. The device does not include a dedicated fan control output; designs requiring fan control functionality must implement this through external logic. The supply voltage range (2.7V to 3.6V) provides broader compatibility. This substitute is suitable for applications where fan control is not required or is managed externally.

Both substitutes are ROHS3 compliant and carry identical ECCN and HTSUS classifications as the original part.

Frequently Asked Questions (FAQ)

Q: Can SE97BTP,547 be used as a direct replacement for SE97TP,147? A: Yes. SE97BTP,547 is the NXP manufacturer-recommended substitute. Electrical specifications, package footprint, and functional outputs are identical. The primary consideration is moisture sensitivity level (MSL 3), which requires compliance with standard moisture handling procedures during storage and assembly.

Q: What is the key difference between SE97BTP,547 and AT30TSE002A-MAH-T? A: SE97BTP,547 is from the same manufacturer (NXP) and provides identical functionality including fan control output. AT30TSE002A-MAH-T is from Microchip Technology and does not include dedicated fan control output. Both devices support I2C/SMBus communication and alarm functions. The Microchip device offers a lower supply voltage minimum (2.7V) and improved accuracy in the 75°C to 95°C range (±1°C).

Q: Are the package footprints compatible between all three parts? A: SE97TP,147 and SE97BTP,547 use identical 8-HWSON (2x3) packages. AT30TSE002A-MAH-T uses 8-WDFN (2x3) package. Both packages are 8-pin, 2x3mm WFDFN with exposed pad and are mechanically compatible for PCB placement. Verify footprint library definitions with your design tools.

Q: Does AT30TSE002A-MAH-T support fan control output? A: No. AT30TSE002A-MAH-T provides output switch and programmable limit functionality but does not include a dedicated fan control output. If fan control is required, implement external logic to drive the fan based on alarm output signals.

Q: What are the moisture sensitivity level implications? A: SE97TP,147 has MSL 1 (unlimited shelf life). SE97BTP,547 and AT30TSE002A-MAH-T have MSL 3 (168 hours). MSL 3 components require storage in dry conditions and must be used within 168 hours of exposure to ambient humidity after opening. Follow standard moisture handling procedures including desiccant storage and baking before reflow soldering.

Q: Are all three parts ROHS3 compliant? A: Yes. SE97TP,147, SE97BTP,547, and AT30TSE002A-MAH-T are all ROHS3 compliant with identical REACH unaffected status and EAR99 ECCN classification.
