Substitute Part Grouping Explanation

Substitution of the OHN3013U with the OHS3120U is based on equivalence across the following critical parameters:

• Identical manufacturer (TT Electronics/Optek Technology)
• Identical function (Unipolar Switch)
• Identical technology (Hall Effect)
• Identical polarization (South Pole)
• Identical supply voltage range (4.5V ~ 24V)
• Identical maximum supply current (7mA)
• Identical maximum output current (25mA)
• Identical output type (Open Collector)
• Identical mounting type (Through Hole)
• Identical package / case (3-SSIP / TO-92-3)
• Identical RoHS compliance status (ROHS3 Compliant)

The OHS3120U represents an active product with extended operational temperature range and improved release threshold specification, making it a direct functional replacement for the obsolete OHN3013U.

Parameter Comparison

Engineering Selection Recommendations

The OHS3120U is the appropriate substitute for the obsolete OHN3013U based on the following engineering criteria:

• Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment
• Identical electrical specifications across supply voltage, current ratings, and output characteristics enable direct circuit-level substitution
• Identical mechanical packaging (TO-92-3 / 3-SSIP) and through-hole mounting support direct PCB layout compatibility
• The OHS3120U offers extended operating temperature range (-40°C ~ 125°C versus -20°C ~ 85°C), providing enhanced thermal performance for demanding applications
• The OHS3120U exhibits improved release threshold sensitivity (2.5mT versus 3mT), resulting in more responsive magnetic field detection
• Active product status of OHS3120U ensures ongoing manufacturer support, availability, and supply chain continuity

Frequently Asked Questions (FAQ)

Q: Can the OHS3120U be used as a direct replacement for the OHN3013U in existing designs?

A: Yes. The OHS3120U is electrically and mechanically equivalent to the OHN3013U. Identical supply voltage range, current ratings, output type, and package configuration enable direct substitution without circuit modification.

Q: What are the key differences between these components?

A: The primary differences are product status and operational specifications. The OHS3120U is an active product with extended operating temperature range (-40°C ~ 125°C versus -20°C ~ 85°C) and improved release threshold (2.5mT versus 3mT). These enhancements do not affect substitution compatibility.

Q: Are there any package or mounting considerations for substitution?

A: No. Both components utilize identical TO-92-3 packaging (3-SSIP case) with through-hole mounting. PCB footprints and lead configurations are identical, requiring no layout modifications.

Q: Does the improved release threshold of the OHS3120U affect circuit operation?

A: The lower release threshold (2.5mT) of the OHS3120U results in more sensitive magnetic field detection compared to the OHN3013U (3mT). This represents an enhancement in responsiveness and does not create compatibility issues in applications designed for the OHN3013U.

Q: Are both components RoHS compliant?

A: Yes. Both the OHN3013U and OHS3120U are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.
