ATS276G-PG-B-A Equivalent & Substitute Parts

Part Overview

The ATS276G-PG-B-A is a digital switch latch Hall Effect magnetic sensor manufactured by Diodes Incorporated, designed for applications requiring magnetic field detection with open collector output. This component operates across a wide supply voltage range (4.6V to 20V) and features a latch function with unidirectional polarization. The part is currently classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATS276G-PG-B-A is determined by the following critical parameters:

• Function & Technology: Latch function with Hall Effect technology for magnetic field detection
• Output Configuration: Open collector output type
• Sensing Characteristics: 5mT trip threshold and -5mT release threshold
• Electrical Specifications: Supply voltage range, maximum supply current, and output current capability
• Operating Environment: Temperature range (-20°C to 85°C) and through-hole mounting requirement
• Compliance: ROHS3 compliance and REACH unaffected status
• Package Compatibility: 4-SSIP package form factor

The AH276Z4-AG1 qualifies as a manufacturer-recommended substitute based on matching core functional parameters, identical sensing thresholds, compatible operating temperature range, and equivalent package specifications.

Parameter Comparison

Engineering Selection Recommendations

The AH276Z4-AG1 is the manufacturer-recommended substitute for the obsolete ATS276G-PG-B-A. Both components maintain identical sensing thresholds (5mT trip, -5mT release), matching operating temperature ranges, and equivalent package specifications. The substitute part is currently in active production status with high inventory availability (50,400 units), ensuring supply chain continuity.

Key considerations for selection:

• Supply Voltage: The substitute operates within a narrower range (4.6V to 16V versus 4.6V to 20V). Applications requiring operation above 16V require circuit redesign or alternative component selection.
• Supply Current: The substitute draws lower maximum supply current (16mA versus 25mA), reducing power consumption in battery-powered applications.
• Output Current: The substitute specifies 350mA maximum output current, providing defined load-driving capability absent in the original part specification.
• Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, suitable for regulated markets.
• Production Status: The substitute's active production status eliminates obsolescence risk for future procurement cycles.

Frequently Asked Questions (FAQ)

Q: Can the AH276Z4-AG1 directly replace the ATS276G-PG-B-A in existing designs?

A: Direct replacement is possible when the application supply voltage does not exceed 16V. The identical sensing thresholds, output type, operating temperature range, and 4-SSIP package enable pin-compatible substitution. Applications requiring supply voltages between 16V and 20V require circuit modification or alternative component selection.

Q: What are the key differences between these two parts?

A: The primary differences are supply voltage range (ATS276G-PG-B-A: 4.6V–20V; AH276Z4-AG1: 4.6V–16V), maximum supply current (25mA versus 16mA), and specified output current capability (350mA for the substitute). The AH276Z4-AG1 includes temperature compensation as an additional feature.

Q: Why is the ATS276G-PG-B-A classified as obsolete?

A: The part has been discontinued by the manufacturer. The AH276Z4-AG1 represents the current production equivalent, offering improved specifications and active supply chain support.

Q: Are there packaging differences between these components?

A: Both parts use the 4-SSIP package form factor with through-hole mounting. The AH276Z4-AG1 is supplied in Tape & Reel (TR) packaging for automated assembly, while the original part packaging is not specified.

Q: What compliance certifications apply to the substitute part?

A: The AH276Z4-AG1 maintains ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the original part.
