ADT7463ARQZ Equivalent & Substitute Parts

Part Overview

The ADT7463ARQZ is a remote thermal controller IC manufactured by onsemi, designed for fan control and temperature monitoring applications. This device integrates internal and external temperature sensing with SMBus output capability, operating across a -40°C to 120°C range. The main part number ADT7463ARQZ is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system design and procurement. The ADT7463ARQZ-REEL variant provides functional equivalence with active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADT7463ARQZ is determined by strict equivalence across the following critical parameters:

• Manufacturer and Series: Both parts are manufactured by onsemi within the dBCool® series
• Functional Specification: Identical fan control and temperature monitoring capabilities
• Sensor Configuration: Both feature internal and external temperature sensing
• Temperature Range and Accuracy: Matching -40°C to 120°C operating range with ±1.5°C accuracy
• Output Interface: Both provide SMBus output for system integration
• Electrical Specifications: Identical 3V to 5.5V supply voltage range
• Package and Mounting: Both use 24-SSOP surface mount packaging with identical physical dimensions
• Moisture Sensitivity: Matching MSL 3 classification

The ADT7463ARQZ-REEL variant differs only in packaging format (Tape & Reel versus standard packaging) and product status (Active versus Obsolete), with no functional or electrical differences.

Parameter Comparison

Engineering Selection Recommendations

The ADT7463ARQZ-REEL is the direct functional equivalent of the ADT7463ARQZ with complete electrical and mechanical compatibility. Selection between these parts should be based on the following criteria:

Product Status: The ADT7463ARQZ is classified as obsolete, while ADT7463ARQZ-REEL maintains active product status. For new designs or long-term production requirements, ADT7463ARQZ-REEL is the preferred selection due to ongoing manufacturer support and availability.

Packaging Format: ADT7463ARQZ-REEL is supplied in Tape & Reel format, suitable for automated assembly processes. Standard packaging of the ADT7463ARQZ may be preferred for manual assembly or low-volume applications, though availability is limited due to obsolete status.

Compliance and Certifications: Both parts maintain identical REACH Unaffected status and MSL 3 moisture sensitivity classification. ADT7463ARQZ-REEL includes explicit RoHS3 compliance certification, providing additional regulatory assurance for applications subject to RoHS requirements.

Inventory and Lead Time: ADT7463ARQZ-REEL demonstrates higher current inventory levels (8955 Pcs) compared to ADT7463ARQZ (5283 Pcs), supporting improved procurement reliability and shorter lead times.

Frequently Asked Questions (FAQ)

Q: Are ADT7463ARQZ and ADT7463ARQZ-REEL electrically identical?

A: Yes. Both parts are functionally and electrically equivalent. They share identical specifications for temperature sensing, fan control output, SMBus interface, supply voltage range, and operating temperature range. The only differences are packaging format and product lifecycle status.

Q: What is the difference between standard packaging and Tape & Reel format?

A: Tape & Reel (TR) packaging is designed for automated pick-and-place assembly equipment, providing components on continuous carrier tape. Standard packaging typically refers to individual or bulk quantities. Both formats contain identical components with no functional differences.

Q: Can ADT7463ARQZ-REEL be used as a direct replacement in existing designs?

A: Yes. ADT7463ARQZ-REEL provides complete pin-for-pin and functional compatibility with ADT7463ARQZ. No circuit modifications or firmware changes are required. The 24-SSOP package dimensions are identical, ensuring PCB footprint compatibility.

Q: Why is ADT7463ARQZ classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support for this specific part number variant. ADT7463ARQZ-REEL remains active, providing a supported alternative with identical functionality.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in: base product number (ADT7463), manufacturer (onsemi), functional capabilities (fan control and temperature monitoring), sensor configuration (internal and external), temperature range (-40°C to 120°C), accuracy (±1.5°C), output interface (SMBus), supply voltage (3V to 5.5V), and package type (24-SSOP surface mount). All these parameters must match for direct substitution.

Q: Is RoHS compliance required for my application?

A: RoHS compliance requirements depend on your application's regulatory jurisdiction and customer specifications. ADT7463ARQZ-REEL explicitly states RoHS3 compliance, while ADT7463ARQZ does not include this certification. If RoHS compliance is mandatory, ADT7463ARQZ-REEL is the appropriate selection.
