SE98ATL,147 Equivalent & Substitute Parts

Part Overview

The SE98ATL,147 is a temperature monitoring system sensor (PMIC) manufactured by NXP USA Inc., designed for DDR applications with internal temperature sensing capabilities. This component operates across a -40°C to 125°C temperature range with ±4°C maximum accuracy and communicates via I2C/SMBus interface with integrated alarm and fan control outputs.

The SE98ATL,147 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this temperature sensor.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SE98ATL,147 is determined by the following critical parameters:

Core Functional Parameters:

• Temperature sensing range: -40°C ~ 125°C
• Accuracy specification: ±4°C (Max)
• Output interface: I2C/SMBus
• Alarm and fan control outputs: Required
• Supply voltage range: 1.7V ~ 3.6V
• Topology: ADC (Sigma Delta), Register Bank

Physical & Compliance Parameters:

• Mounting type: Surface Mount
• Base product number: SE98 (same family)
• RoHS compliance: ROHS3 Compliant
• REACH status: REACH Unaffected

The SE98ATP,547 qualifies as a manufacturer-recommended substitute because it maintains identical functional specifications, operates within the same electrical parameters, belongs to the same SE98 product family, and meets all required compliance certifications. The primary difference is packaging configuration and product status (Active vs. Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The SE98ATP,547 is the manufacturer-recommended substitute for the obsolete SE98ATL,147. Both components are manufactured by NXP, maintain identical electrical and functional specifications, and comply with ROHS3 and REACH requirements.

The SE98ATP,547 carries Active product status, ensuring continued availability and supply chain support. This substitution is appropriate for new designs and production continuity applications.

The primary distinction between these parts is the package variant (8-HXSON vs. 8-HWSON) and moisture sensitivity classification. The SE98ATP,547 specifies MSL 3 (168 Hours) compared to MSL 1 (Unlimited) for the SE98ATL,147. This difference requires evaluation based on storage and handling conditions in your manufacturing environment.

Frequently Asked Questions (FAQ)

Q: Can SE98ATP,547 be used as a direct replacement for SE98ATL,147?

A: Yes. Both parts share identical functional specifications including temperature range (-40°C to 125°C), accuracy (±4°C), supply voltage (1.7V to 3.6V), output interface (I2C/SMBus), and alarm/fan control capabilities. The SE98ATP,547 is the manufacturer-recommended substitute.

Q: What is the difference between the 8-HXSON and 8-HWSON packages?

A: Both are 8-pin surface mount packages with 2x3mm dimensions and exposed pads. The designations reflect different package variants within the same physical footprint. PCB layout compatibility should be verified with package datasheets.

Q: Does the moisture sensitivity level difference affect substitution?

A: The SE98ATP,547 specifies MSL 3 (168 Hours) versus MSL 1 (Unlimited) for the SE98ATL,147. This affects storage and handling requirements. Evaluate your manufacturing environment's humidity control and component shelf life requirements to determine if this difference impacts your production process.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both SE98ATL,147 and SE98ATP,547 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: Why is SE98ATL,147 classified as obsolete?

A: The SE98ATL,147 has reached end-of-life status. The SE98ATP,547 remains in active production and is the recommended path for ongoing supply and new designs.
