AH180-PL-B Equivalent & Substitute Parts

Part Overview

The AH180-PL-B is a magnetic switch with omnipolar Hall Effect sensing 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 AH180-PL-B is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

The AH180-PL-B has one direct equivalent substitute: AH180-PG-B. This substitution is valid based on the following criteria:

Matching Parameters:

• Identical manufacturer (Diodes Incorporated)
• Identical base product number (AH180)
• Identical function (Omnipolar Switch)
• Identical sensing technology (Hall Effect)
• Identical polarization capability (North Pole, South Pole)
• Identical sensing range (±6mT Trip, ±1mT Release)
• Identical supply voltage range (2.5V ~ 5.5V)
• Identical maximum supply current (16µA)
• Identical output type (Open Drain)
• Identical operating temperature range (-40°C ~ 85°C)
• Identical package type (3-SIP)
• Identical mounting type (Through Hole)
• Identical compliance certifications (ROHS3, REACH Unaffected, EAR99)

The primary distinction between these parts is product status: AH180-PL-B is obsolete while AH180-PG-B is active, and packaging format (AH180-PL-B uses standard packaging while AH180-PG-B is supplied in bulk).

Parameter Comparison

Engineering Selection Recommendations

The AH180-PG-B is the direct substitute for the obsolete AH180-PL-B. Selection of AH180-PG-B is appropriate for all applications currently using or specifying AH180-PL-B due to complete electrical and mechanical equivalence across all defined parameters.

The active product status of AH180-PG-B ensures ongoing availability and manufacturer support. Both parts maintain identical compliance certifications including ROHS3 compliance and REACH unaffected status, confirming regulatory equivalence for applications subject to these requirements.

The 3-SIP through-hole package format is identical between both parts, enabling direct board-level substitution without PCB redesign. Supply voltage range, sensing characteristics, and output configuration remain unchanged, confirming functional interchangeability in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can AH180-PG-B be used as a direct replacement for AH180-PL-B?

A: Yes. AH180-PG-B is electrically and mechanically equivalent to AH180-PL-B across all specified parameters including sensing range, supply voltage, output type, operating temperature, and package format.

Q: What is the difference between AH180-PL-B and AH180-PG-B?

A: The primary differences are product status (AH180-PL-B is obsolete; AH180-PG-B is active) and packaging format (bulk packaging for AH180-PG-B). All electrical and mechanical specifications are identical.

Q: Are there any compliance differences between these parts?

A: No. Both AH180-PL-B and AH180-PG-B carry identical compliance certifications: ROHS3 compliant, REACH unaffected, and EAR99 classification.

Q: Will AH180-PG-B work in existing designs using AH180-PL-B?

A: Yes. The identical 3-SIP through-hole package, supply voltage range (2.5V ~ 5.5V), sensing range (±6mT trip, ±1mT release), and open drain output enable direct substitution without circuit modification.

Q: Why should I transition from AH180-PL-B to AH180-PG-B?

A: AH180-PL-B is obsolete, making long-term availability uncertain. AH180-PG-B is an active product with confirmed ongoing manufacturer support and availability.
