AH180-PL-A Equivalent & Substitute Parts

Part Overview

The AH180-PL-A is an omnipolar magnetic switch manufactured by Diodes Incorporated, utilizing Hall Effect technology for digital switching applications. This component operates across a supply voltage range of 2.5V to 5.5V with an open drain output configuration and is housed in a 3-SIP package with formed leads. The part is classified as obsolete, making identification of active equivalent alternatives essential for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution of the AH180-PL-A is determined by strict equivalence across the following critical parameters:

• Technology & Function: Hall Effect omnipolar switching capability
• Electrical Specifications: Supply voltage range 2.5V ~ 5.5V, maximum supply current 16µA, open drain output
• Sensing Characteristics: Magnetic polarization (North Pole, South Pole detection)
• Environmental Compliance: ROHS3 compliance, REACH unaffected status, MSL 1 rating
• Thermal Range: Operating temperature -40°C ~ 85°C (TA)
• Package Compatibility: 3-SIP through-hole mounting with formed leads

The identified substitutes AH180-PG-A and AH180-PG-B maintain electrical and functional equivalence while offering active product status. Variations in sensing range release threshold (±1mT vs. ±2mT) and packaging format (Cut Tape vs. Bulk) represent the only parameter differences and do not affect core switching functionality.

Parameter Comparison

Engineering Selection Recommendations

Both AH180-PG-A and AH180-PG-B are direct functional equivalents to the obsolete AH180-PL-A, with active product status enabling continued procurement and design support. Selection between the two substitutes is determined by application-specific requirements and packaging availability:

AH180-PG-A is supplied in Cut Tape (CT) packaging format, suitable for automated assembly processes and high-volume production environments.

AH180-PG-B is supplied in Bulk packaging format and features identical electrical specifications to the original AH180-PL-A, including the ±1mT release threshold. This variant is recommended for applications where the original release threshold specification is a critical design parameter.

Both substitutes maintain full compliance with ROHS3 and REACH requirements, with MSL 1 rating indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can AH180-PG-A and AH180-PG-B be used interchangeably with AH180-PL-A?

A: Both substitutes maintain electrical and functional equivalence across all critical parameters including supply voltage, current consumption, output type, and operating temperature range. The primary differences are product status (active vs. obsolete), packaging format, and sensing range release threshold. AH180-PG-B matches the original release threshold specification (±1mT), while AH180-PG-A specifies ±2mT release.

Q: What is the significance of the sensing range release threshold difference?

A: The release threshold determines the magnetic field strength at which the switch transitions from active to inactive state. AH180-PL-A and AH180-PG-B both specify ±1mT release, while AH180-PG-A specifies ±2mT release. Applications with hysteresis-sensitive designs should select AH180-PG-B to maintain original specifications.

Q: Are there packaging compatibility considerations for PCB assembly?

A: All three parts utilize 3-SIP through-hole packages with formed leads, ensuring mechanical and electrical compatibility with existing PCB designs. Packaging format differences (Cut Tape vs. Bulk) affect procurement and handling procedures but not board-level integration.

Q: Do the substitute parts maintain the same compliance certifications?

A: Yes. Both AH180-PG-A and AH180-PG-B are ROHS3 compliant, REACH unaffected, and carry MSL 1 rating, matching the original AH180-PL-A specifications.

Q: Why is the original AH180-PL-A classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by Diodes Incorporated. The active substitutes AH180-PG-A and AH180-PG-B provide equivalent functionality for new designs and ongoing production requirements.
