SE98ATP,147 Equivalent & Substitute Parts

Part Overview

The SE98ATP,147 is a temperature monitoring system sensor manufactured by NXP USA Inc., designed for DDR applications with internal temperature sensing capabilities. This component operates across a -40°C to 125°C range with I2C/SMBus output interface and integrated alarm and fan control functions. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SE98ATP,147 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Package / Case: 8-WFDFN Exposed Pad (physical and electrical compatibility)
• Output Interface: I2C/SMBus protocol support
• Sensing Temperature Range: Minimum coverage of -40°C ~ 125°C
• Supply Voltage: Overlap with 1.7V ~ 3.6V range
• Mounting Type: Surface Mount

Functional Requirements:

• Temperature monitoring capability with internal sensor
• Alarm output functionality
• Fan control output functionality

Two substitute parts meet these criteria:

SE98ATP,547 (NXP Semiconductors) — Direct manufacturer alternative with identical electrical specifications and package, differing only in product status (Active vs. Obsolete) and packaging format.

AT30TSE002A-MAH-T (Microchip Technology) — Cross-manufacturer substitute with compatible package, I2C/SMBus interface, and overlapping temperature range, though with enhanced accuracy specification and different feature set.

Parameter Comparison

Engineering Selection Recommendations

SE98ATP,547 is the primary substitute for SE98ATP,147. Both parts are NXP products with identical electrical and functional specifications. SE98ATP,547 maintains active product status and is available in higher inventory quantities, providing supply continuity. The transition from Obsolete to Active status eliminates long-term availability risk. Packaging format differs (Cut Tape & Digi-Reel® vs. original specification), but electrical compatibility is complete.

AT30TSE002A-MAH-T serves as a secondary cross-manufacturer alternative. This Microchip Technology component provides superior accuracy (±1°C vs. ±4°C) and maintains I2C/SMBus protocol compatibility. The sensing temperature range (-20°C ~ 125°C) covers the critical operating window, though the lower bound does not extend to -40°C. Supply voltage range (2.7V ~ 3.6V) is narrower than the original specification. The AT30TSE002A-MAH-T includes programmable limit and shutdown mode features not explicitly specified in the original part. Selection of this substitute requires confirmation that the -20°C lower temperature limit is acceptable for the application and that the 2.7V minimum supply voltage meets system requirements.

Both substitutes maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can SE98ATP,547 be used as a direct replacement for SE98ATP,147?

A: Yes. SE98ATP,547 is electrically and functionally identical to SE98ATP,147. Both components share the same sensing temperature range (-40°C ~ 125°C), accuracy specification (±4°C), supply voltage range (1.7V ~ 3.6V), I2C/SMBus output interface, alarm output, and fan control output. The primary difference is product status: SE98ATP,547 is Active while SE98ATP,147 is Obsolete. Packaging format differs (Cut Tape & Digi-Reel® vs. original), but this does not affect electrical compatibility.

Q: What are the key differences between SE98ATP,547 and AT30TSE002A-MAH-T?

A: Both parts use the same 8-WFDFN package and I2C/SMBus interface. AT30TSE002A-MAH-T offers superior accuracy (±1°C vs. ±4°C) and includes programmable limit and shutdown mode features. However, AT30TSE002A-MAH-T has a narrower sensing temperature range (-20°C ~ 125°C vs. -40°C ~ 125°C) and lower minimum supply voltage (2.7V vs. 1.7V). Selection depends on whether the application requires the full -40°C lower temperature limit and 1.7V supply voltage support.

Q: Are all three parts pin-compatible?

A: All three parts use the 8-WFDFN Exposed Pad package with identical physical dimensions (2x3 mm). Pin compatibility is confirmed for I2C/SMBus communication. However, functional differences in alarm and fan control outputs between SE98ATP,147/SE98ATP,547 and AT30TSE002A-MAH-T require firmware or firmware configuration review to ensure proper signal handling.

Q: What is the impact of the MSL (Moisture Sensitivity Level) difference?

A: SE98ATP,147 has MSL 1 (Unlimited moisture exposure tolerance), while both SE98ATP,547 and AT30TSE002A-MAH-T have MSL 3 (168-hour moisture exposure limit). This affects storage and handling procedures. Components with MSL 3 require controlled humidity storage and have a 168-hour floor life after moisture exposure. If the original design relied on MSL 1 unlimited storage, substitute parts require updated inventory management and handling protocols.

Q: Can AT30TSE002A-MAH-T replace SE98ATP,147 in applications requiring -40°C operation?

A: No. AT30TSE002A-MAH-T sensing temperature range begins at -20°C, not -40°C. Applications requiring full -40°C ~ 125°C coverage must use SE98ATP,547. AT30TSE002A-MAH-T is suitable only for applications where the minimum operating temperature is -20°C or higher.

Q: What supply voltage considerations apply when substituting?

A: SE98ATP,147 and SE98ATP,547 both support 1.7V ~ 3.6V supply range. AT30TSE002A-MAH-T requires minimum 2.7V supply. If the system operates below 2.7V, AT30TSE002A-MAH-T cannot be used. Verify system supply voltage specifications before selecting AT30TSE002A-MAH-T as a substitute.
