LLE105000 Liquid Level Sensor - Equivalent & Substitute Parts

Part Overview

The LLE105000 is a liquid level sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for push-pull high-dry output applications in panel mount configurations. This sensor operates across a temperature range of -25°C to 80°C and is compatible with voltage supplies between 5V and 12V. The product is currently classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where legacy component compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LLE105000 is based on the following critical parameters that define functional equivalence:

Primary Compatibility Criteria:

• Sensor type: Liquid level detection
• Output type: Push-pull configuration
• Operating temperature range: -25°C to 80°C (minimum requirement)
• Housing material: Polysulfone (PES)
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance status

Secondary Compatibility Considerations:

• Voltage rating overlap (substitute must operate within or encompass the 5V to 12V range)
• Current draw specifications (substitute specifications must be compatible with system design)
• ECCN classification alignment (EAR99)

The LLC105000 from SST Sensing Ltd. meets these substitution criteria through matching sensor type, push-pull output configuration, identical operating temperature range, identical housing material, and equivalent RoHS compliance status. Differences in mounting type (threaded versus panel mount) and output configuration detail (digital versus high-dry) represent design trade-offs that must be evaluated within specific application contexts.

Engineering Selection Recommendations

For Direct Replacement Applications:

The LLC105000 provides functional substitution for the obsolete LLE105000 based on matching sensor type, push-pull output configuration, operating temperature range, and housing material. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Voltage Compatibility:

The LLC105000 voltage rating of 4.5V to 15.4V encompasses the original LLE105000 specification of 5V to 12V, providing expanded operational flexibility within the substitute design.

Current Draw Differential:

The LLC105000 operates at 2.5 mA compared to the LLE105000 at 15 mA. This represents a significant reduction in power consumption. System designs dependent on the higher current draw of the original part must be re-evaluated for the substitute specification.

Mechanical Interface Modification:

The LLE105000 uses panel mount configuration while the LLC105000 uses threaded mounting. Physical integration into existing assemblies requires mechanical redesign or adapter solutions.

Compliance Status:

Both parts maintain RoHS compliance. The LLC105000 meets ROHS3 standard, representing current regulatory alignment. Both parts carry EAR99 ECCN classification.

Frequently Asked Questions (FAQ)

Q: Can the LLC105000 directly replace the LLE105000 without any modifications?

A: Direct mechanical replacement is not possible due to different mounting types (panel mount versus threaded). Electrical compatibility exists within the specified voltage and temperature ranges, but system integration requires mechanical redesign or mounting adapter solutions.

Q: What is the significance of the current draw difference between these parts?

A: The LLE105000 draws 15 mA while the LLC105000 draws 2.5 mA. This difference affects power supply sizing, thermal management, and system power budget calculations. Existing designs must verify that reduced current draw does not impact signal integrity or system performance.

Q: Are both parts RoHS compliant?

A: Yes. The LLE105000 is RoHS Compliant, and the LLC105000 is ROHS3 Compliant. Both meet regulatory requirements for restricted substance elimination.

Q: Why is the LLE105000 classified as obsolete?

A: Product obsolescence indicates that the manufacturer has discontinued production. The LLC105000 represents an active production alternative that fulfills the same functional requirements.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching sensor type (liquid level detection), output configuration (push-pull), operating temperature range (-25°C to 80°C), housing material (polysulfone), and compliance status (RoHS). Differences in mounting type and output signal format represent design trade-offs requiring application-specific evaluation.

Q: Does the expanded voltage range of the LLC105000 create any compatibility concerns?

A: The LLC105000 voltage range of 4.5V to 15.4V encompasses the LLE105000 specification of 5V to 12V. No compatibility concerns exist within the original operating voltage window. The expanded range provides additional operational flexibility.

Q: What inventory status should be considered for procurement decisions?

A: The LLE105000 has 749 pieces in stock as new original inventory. The LLC105000 has 1142 pieces in stock. For long-term supply chain planning, the active production status of the LLC105000 provides greater assurance of continued availability compared to the obsolete LLE105000.
