DN6849 Equivalent & Substitute Parts

Part Overview

The DN6849 is a bipolar Hall Effect magnetic switch manufactured by Panasonic Electronic Components in a 3-SIP package configuration. This component functions as a digital switch with open collector output, designed for magnetic field detection applications requiring bipolar switching capability. The DN6849 is classified as obsolete, making identification of functionally equivalent substitute components necessary for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the DN6849 are identified based on the following critical parameters that determine functional equivalence:

• Hall Effect technology platform
• Through hole mounting configuration
• Open collector/open drain output topology
• Supply voltage compatibility within the 4.5V – 16V range
• Operating temperature range encompassing the DN6849 specification
• Similar magnetic sensing range and switching characteristics

The identified substitutes (US1881EUA-AAA-000-BU and US1881LUA-AAA-000-BU) are Melexis Technologies Hall Effect sensors that maintain core functional compatibility through shared technology, output type, and mounting methodology. Both substitutes operate within the DN6849 supply voltage envelope and provide through-hole packaging suitable for direct circuit integration.

Parameter Comparison

Engineering Selection Recommendations

Both US1881 variants are active products with current manufacturing support, addressing the obsolescence status of the DN6849. Selection between the two Melexis substitutes depends on application temperature requirements:

• US1881EUA-AAA-000-BU: Suitable for applications operating within -40°C to 85°C range. Provides ROHS3 compliance and REACH unaffected status.

• US1881LUA-AAA-000-BU: Required for applications requiring extended temperature operation to 150°C. Maintains ROHS3 compliance and REACH unaffected status with identical electrical characteristics to the US1881EUA variant.

Both substitutes exceed the DN6849 output current capability (50mA versus 10µA) and operate within an expanded supply voltage range (4.6V – 24V versus 4.5V – 16V), providing design flexibility for circuit integration. Package transition from 3-SSIP to TO-92-3 requires physical layout modification but maintains three-pin through-hole connectivity.

Frequently Asked Questions (FAQ)

Q: Can US1881 series sensors directly replace DN6849 in existing circuit layouts?

A: Physical package differences exist between 3-SSIP (DN6849) and TO-92-3 (US1881 series). While both are three-pin through-hole configurations, pin spacing and body dimensions differ. PCB layout modification is required for direct substitution.

Q: What is the functional difference between open collector and open drain outputs?

A: Both output topologies provide similar switching behavior in digital circuits. Open collector (DN6849) and open drain (US1881 series) both require external pull-up resistors for proper operation. Circuit compatibility is maintained when pull-up resistor values are appropriately selected for the application voltage and load requirements.

Q: Which US1881 variant should be selected for temperature-critical applications?

A: The US1881LUA-AAA-000-BU extends the operating temperature range to 150°C, accommodating high-temperature environments. The US1881EUA-AAA-000-BU is suitable for standard industrial temperature ranges (-40°C to 85°C). Selection depends on specific application thermal requirements.

Q: Are the Melexis US1881 sensors compatible with the DN6849 supply voltage specification?

A: Yes. The DN6849 operates at 4.5V – 16V, which falls within the US1881 supply range of 4.6V – 24V. Both substitutes maintain stable operation across the DN6849 voltage envelope.

Q: What compliance certifications apply to the substitute components?

A: Both US1881EUA-AAA-000-BU and US1881LUA-AAA-000-BU carry ROHS3 compliance and REACH unaffected status. Both share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications with the DN6849.
