DN6849SE Equivalent & Substitute Parts

Part Overview

The DN6849SE is a bipolar Hall Effect magnetic switch manufactured by Panasonic Electronic Components in a 3-SSIP package. This digital switch operates as an open collector device with temperature compensation, designed for magnetic field detection applications. The part is currently obsolete, making equivalent substitutes necessary for ongoing design support and component sourcing. Substitute parts must maintain functional compatibility through matching electrical characteristics, package compatibility, and sensing technology.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the DN6849SE is based on the following critical parameters:

• Technology: Hall Effect magnetic sensing
• Output Configuration: Open collector/open drain topology for logic-level switching
• Package Compatibility: TO-92-3 through-hole package
• Supply Voltage Range: Minimum 4.6V to support low-voltage applications
• Moisture Sensitivity: MSL 1 rating for unlimited shelf life
• Mounting: Through-hole configuration

The identified substitutes (US1881EUA-AAA-000-BU and US1881LUA-AAA-000-BU) are Melexis Technologies Hall Effect switches available in TO-92-3 packages. Both parts employ open drain output architecture and operate within compatible voltage ranges. The primary distinction between substitute options relates to operating temperature range and test condition specifications.

Parameter Comparison

Engineering Selection Recommendations

US1881LUA-AAA-000-BU is the primary substitute for applications requiring extended operating temperature range up to 150°C. This part maintains active product status with ROHS3 compliance and REACH unaffected certification, ensuring long-term availability and regulatory alignment.

US1881EUA-AAA-000-BU serves as an alternative for applications with operating temperature requirements up to 85°C. This variant also maintains active status with equivalent compliance certifications.

Both substitutes provide expanded supply voltage range (4.6V – 24V) compared to the DN6849SE (4.5V – 16V), enabling compatibility with a broader range of system designs. The transition from bipolar switch to latch function and from open collector to open drain output requires circuit-level evaluation to confirm functional equivalence in the target application.

Frequently Asked Questions (FAQ)

Q: Can US1881EUA-AAA-000-BU and US1881LUA-AAA-000-BU be used interchangeably?

A: Both parts share identical electrical specifications and package configuration. Selection depends on operating temperature requirements. Use US1881LUA-AAA-000-BU for applications exceeding 85°C; use US1881EUA-AAA-000-BU for applications within -40°C to 85°C range.

Q: What is the functional difference between bipolar switch and latch operation?

A: The DN6849SE operates as a bipolar switch, responding to magnetic field polarity changes. The US1881 series operates as a latch, maintaining output state until a reverse magnetic field is applied. Circuit design must accommodate this functional distinction.

Q: Are the TO-92-3 packages physically compatible?

A: Both substitute parts use TO-92-3 Short Body packages, which are mechanically compatible with TO-92-3 through-hole footprints. Verify PCB layout clearances for short body variant dimensions.

Q: Do the substitutes meet the same compliance requirements?

A: US1881EUA-AAA-000-BU and US1881LUA-AAA-000-BU are ROHS3 compliant and REACH unaffected. Both carry MSL 1 rating and EAR99 ECCN classification, matching the regulatory profile of the DN6849SE.

Q: What is the impact of increased output current capability?

A: Substitute parts provide 50mA maximum output current versus 10µA for the DN6849SE. This expanded capability enables direct logic-level switching without intermediate buffering stages in many applications.
