Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATS276H-PG-B-A is determined by the following critical parameters:

• Functional equivalence: Hall Effect latch technology with open collector output
• Sensing characteristics: 5mT trip threshold and -5mT release threshold
• Electrical compatibility: Supply voltage range and output current capability
• Thermal performance: Operating temperature range of -20°C to 85°C
• Physical form factor: Through-hole mounting with 4-pin configuration
• Regulatory compliance: ROHS3 compliance and REACH unaffected status

The AH276Z4-AG1 qualifies as a manufacturer-recommended substitute based on these parameters. Both devices share identical sensing thresholds, operating temperature range, and regulatory certifications. The substitute maintains Hall Effect latch functionality with open collector output architecture.

Parameter Comparison

Engineering Selection Recommendations

The AH276Z4-AG1 is the manufacturer-recommended substitute for the obsolete ATS276H-PG-B-A. Both components maintain identical sensing thresholds, operating temperature specifications, and regulatory compliance status. The substitute is currently in active production with substantial inventory availability (50,400 units).

Design considerations for substitution:

• Supply voltage: The AH276Z4-AG1 operates within 4.6V to 16V, which is a subset of the original 4.6V to 20V range. Applications requiring supply voltages above 16V require circuit redesign.
• Supply current: The substitute draws a maximum of 16mA compared to the original 25mA specification, representing improved power efficiency.
• Output current: The AH276Z4-AG1 specifies a maximum output current of 350mA, providing enhanced load-driving capability.
• Regulatory status: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring continued regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the AH276Z4-AG1 directly replace the ATS276H-PG-B-A in existing designs?

A: Direct replacement is possible when the application supply voltage does not exceed 16V. The substitute maintains identical sensing thresholds, output type, and operating temperature range. Verify that your circuit design operates within the 4.6V to 16V supply voltage window.

Q: What is the difference in package designation between 4-SIP and TO-94?

A: Both designations refer to the same 4-pin through-hole package form factor (4-SSIP). The supplier device package designation differs between manufacturers, but the physical and electrical interfaces are equivalent.

Q: Are there any performance differences in magnetic sensing between these parts?

A: Both components share identical sensing thresholds of 5mT trip and -5mT release. The AH276Z4-AG1 includes temperature compensation as an additional feature, which may improve stability across the operating temperature range.

Q: What inventory considerations apply to this substitution?

A: The ATS276H-PG-B-A is obsolete with limited remaining stock (1,980 units). The AH276Z4-AG1 is in active production with substantial availability (50,400 units in tape and reel packaging), ensuring long-term supply continuity.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the ATS276H-PG-B-A and AH276Z4-AG1 are ROHS3 compliant and REACH unaffected, maintaining identical regulatory status for applications requiring these certifications.
