ADT7475ARQZ Equivalent & Substitute Parts

Part Overview

The ADT7475ARQZ is a remote thermal controller IC from onsemi's dBCool® series, designed for fan control and temperature monitoring applications. It integrates internal and external temperature sensing with SMBus output capability, operating across -40°C to 125°C. The ADT7475ARQZ is currently listed 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 ADT7475ARQZ is determined by strict alignment across the following critical parameters:

• Base product number (ADT7475 series)
• Functional capability (Fan Control, Temp Monitor)
• Sensor configuration (Internal and External)
• Temperature sensing range (-40°C ~ 125°C)
• Temperature accuracy (±1.5°C Max)
• Output interface (SMBus)
• Supply voltage specification (3V ~ 3.6V)
• Package and case dimensions (16-SSOP, 0.154", 3.90mm Width)
• Surface mount compatibility

The ADT7475ARQZ-REEL qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The distinction between these part numbers reflects packaging and distribution format only.

Parameter Comparison

Engineering Selection Recommendations

The ADT7475ARQZ-REEL is the direct functional equivalent for the obsolete ADT7475ARQZ. Both parts share identical electrical specifications, thermal characteristics, and mechanical packaging. The primary distinction is product status: ADT7475ARQZ-REEL maintains active production status with confirmed inventory availability (30,200 pcs), while the original ADT7475ARQZ is obsolete.

For new designs and ongoing system support, ADT7475ARQZ-REEL is the appropriate selection. The packaging designation (Cut Tape & Digi-Reel®) indicates standard distribution format suitable for automated assembly processes. Both parts comply with REACH regulations and carry identical moisture sensitivity ratings.

Frequently Asked Questions (FAQ)

Q: Can ADT7475ARQZ-REEL be used as a direct replacement for ADT7475ARQZ?

A: Yes. Both parts are electrically and mechanically identical. The suffix "-REEL" indicates packaging format (Digi-Reel® distribution) rather than functional differences. Pin configuration, electrical performance, and thermal characteristics are identical.

Q: What is the difference between these part numbers?

A: The ADT7475ARQZ-REEL differs only in packaging and distribution method. The base ADT7475ARQZ uses standard cut tape packaging, while the -REEL variant uses onsemi's Digi-Reel® format for high-volume automated assembly. Electrical and mechanical specifications are unchanged.

Q: Is the 16-SSOP package compatible with existing PCB designs?

A: Yes. Both parts use the identical 16-SSOP package with 0.154" width and 3.90mm dimensions. PCB footprints, solder reflow profiles, and assembly processes require no modification.

Q: What is the product status difference, and does it affect compatibility?

A: ADT7475ARQZ is obsolete; ADT7475ARQZ-REEL is active production. This status difference does not affect electrical or mechanical compatibility. The active status of ADT7475ARQZ-REEL ensures continued availability and supply chain reliability.

Q: Are there compliance or certification differences?

A: Both parts maintain identical REACH compliance status (REACH Unaffected) and moisture sensitivity ratings (MSL 1 - Unlimited). No compliance or certification differences exist between the two part numbers.
