LY-30 Equivalent and Substitute Parts

Part Overview

The LY-30 is a magnetic reed switch manufactured by Coto Technology, classified as a Magnetic Sensor with SPST-NO (Single-Pole Single-Throw Normally Open) output configuration. The component features wire leads termination and operates within the temperature range of -20°C to 85°C. The product has reached obsolete status, making it necessary to identify equivalent components that maintain functional and electrical compatibility for ongoing applications and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute compatibility for the LY-30 is determined by the following core parameters:

• Output Type: SPST-NO configuration ensures identical switching behavior
• Actuator Material: Magnet-actuated operation provides functional equivalence
• Termination Style: Wire Leads enable direct mechanical and electrical connection
• Category: Magnetic Sensors classification confirms functional category alignment

The substitute part 59140-010 satisfies all core compatibility criteria. Both components are reed switches with identical output types, actuator materials, and termination styles. While the substitute features a Flange Mount package versus the Rectangular package of the original, and extends the operating temperature range and actuation specifications, these represent functional improvements rather than incompatibilities.

Parameter Comparison

Engineering Selection Recommendations

The 59140-010 (Littelfuse Inc.) serves as a direct functional substitute for the obsolete LY-30. Both components meet identical core switching requirements: SPST-NO output, magnet actuation, and wire lead termination.

The substitute part carries Active product status, ensuring continued supply and manufacturing support. The 59140-010 provides extended temperature operating range (-40°C ~ 105°C versus -20°C ~ 85°C) and advanced compliance status (ROHS3 versus RoHS Compliant), representing current-generation technology.

The primary consideration is package geometry: the substitute features Flange Mount configuration while the original uses Rectangular, Wire Leads. Applications requiring identical physical form factor require verification of mounting compatibility. The extended actuation specifications (Must Operate: 4.44mm; Must Release: 20.32mm) define the magnetic operating window and do not present incompatibility.

Both components maintain identical RoHS and REACH compliance classifications, suitable for equivalent regulatory requirements.

Frequently Asked Questions (FAQ)

Q: What makes the 59140-010 a suitable substitute for the LY-30? A: Both components are SPST-NO magnetic reed switches with identical output types, actuator materials, and wire lead termination. The core switching functionality and electrical characteristics align across both parts, enabling direct functional substitution.

Q: Does package geometry affect substitution? A: The LY-30 uses Rectangular, Wire Leads packaging while the 59140-010 uses Flange Mount configuration. Physical form factor differs, requiring verification of mechanical fit within the application assembly. Electrical and functional compatibility remains unchanged.

Q: How do the operating temperature ranges compare? A: The LY-30 operates from -20°C to 85°C. The 59140-010 extends this range to -40°C to 105°C, covering broader environmental conditions. Applications within the original LY-30 temperature window are fully compatible with the substitute.

Q: What is the significance of Active versus Obsolete product status? A: The LY-30 is obsolete, indicating discontinued manufacturing and limited inventory availability. The 59140-010 is Active, ensuring continued production, supply chain reliability, and long-term availability for new designs and ongoing production requirements.

Q: Are there compliance differences? A: Both parts are RoHS and REACH compliant. The substitute carries ROHS3 designation, representing the current compliance standard, while the original is listed as RoHS Compliant. This represents a compliance enhancement rather than incompatibility.

Q: What are the Must Operate and Must Release specifications for the 59140-010? A: Must Operate is 4.44mm and Must Release is 20.32mm. These parameters define the magnetic actuation distance window. The LY-30 specifications for these parameters were not provided in the available documentation.
