AH180-PG-A-S Equivalent & Substitute Parts

Part Overview

The AH180-PG-A-S is an omnipolar magnetic switch utilizing Hall Effect technology, manufactured by Diodes Incorporated. This component functions as a digital switch with open drain output, designed for applications requiring detection of magnetic fields from both north and south poles. The part is currently classified as obsolete, necessitating identification of active equivalent components to maintain design continuity and ensure long-term supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AH180-PG-A-S is based on strict equivalence across the following critical parameters:

• Functional Equivalence: Omnipolar switch with Hall Effect technology
• Electrical Compatibility: Supply voltage range 2.5V ~ 5.5V, open drain output configuration
• Magnetic Sensing: Omnipolar detection (North Pole and South Pole sensitivity)
• Package Compatibility: 3-SIP through-hole form factor with formed leads
• Environmental Compliance: ROHS3 compliance and operating temperature range -40°C ~ 85°C

The substitute part AH1808-P-A meets all these criteria while maintaining active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The AH1808-P-A is the direct substitute for the obsolete AH180-PG-A-S. Both components are manufactured by Diodes Incorporated and maintain identical core electrical and mechanical specifications. The substitute part offers the advantage of active product status, ensuring continued availability and supply chain support.

The AH1808-P-A is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The component is available in Cut Tape packaging, supporting both prototype and production-volume applications.

The primary difference between the two parts is the release sensing range specification: the AH1808-P-A specifies ±5mT release versus the ±2mT release of the original part. This represents a relaxed specification that does not compromise functional compatibility in applications designed for the original part's performance envelope.

Frequently Asked Questions (FAQ)

Q: Can the AH1808-P-A be used as a direct replacement for the AH180-PG-A-S?

A: Yes. Both components share identical supply voltage ranges (2.5V ~ 5.5V), omnipolar Hall Effect sensing technology, open drain output configuration, 3-SIP package form factor, and operating temperature range (-40°C ~ 85°C). The trip sensing threshold (±6mT) is identical across both parts.

Q: What is the difference in the release sensing range between these parts?

A: The AH180-PG-A-S specifies ±2mT release, while the AH1808-P-A specifies ±5mT release. This difference represents a relaxed specification in the substitute part and does not prevent functional substitution in applications designed for the original component.

Q: Are there packaging differences between these parts?

A: The AH1808-P-A is available in Cut Tape (CT) packaging. The original part's packaging format is not specified in the available data. Both maintain the same 3-SIP through-hole form factor with formed leads.

Q: Does the AH1808-P-A meet current compliance standards?

A: Yes. The AH1808-P-A is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the maximum output current for the AH1808-P-A?

A: The AH1808-P-A specifies a maximum output current of 2.5mA. The original AH180-PG-A-S does not provide this specification in available documentation.
