LSXYNB3K Snap Action Switch - Equivalent & Substitute Parts

Part Overview

The LSXYNB3K is a snap action switch manufactured by Honeywell Sensing and Productivity Solutions, classified as a Single Pole Double Throw (SPDT) switch with chassis mount configuration. This component is rated for 10A AC at 120V and 800mA DC at 115V, featuring side rotary actuation without lever and screw terminal connections. The LSXYNB3K is designated as obsolete product status, necessitating identification of active equivalent components to maintain supply chain continuity for applications requiring identical electrical and mechanical specifications.

• Moisture Sensitivity Level 1

The LSXN3K meets all specified parameters and maintains active product status within the LSX series from Honeywell Sensing and Productivity Solutions.

Parameter Comparison

Engineering Selection Recommendations

The LSXN3K is a direct functional equivalent to the obsolete LSXYNB3K. Both components share identical electrical ratings, mechanical specifications, and compliance certifications. The LSXN3K maintains active product status within the LSX series, ensuring continued availability and supply chain support.

The operating temperature range of the LSXN3K (-1°C to 121°C) is narrower than the LSXYNB3K (-29°C to 121°C). Applications requiring operation below -1°C must evaluate this specification difference against system requirements.

Both components are RoHS Compliant with Moisture Sensitivity Level 1, supporting environmental and regulatory compliance requirements. The LSXN3K is available in bulk packaging, whereas the LSXYNB3K was supplied with standard packaging.

Frequently Asked Questions (FAQ)

Q: Can the LSXN3K directly replace the LSXYNB3K in existing applications?

A: The LSXN3K provides electrical and mechanical equivalence across all specified parameters. The primary consideration is the operating temperature range: the LSXN3K operates from -1°C to 121°C, while the LSXYNB3K operates from -29°C to 121°C. Applications requiring operation below -1°C must confirm compatibility with system requirements.

Q: What are the key electrical specifications that define substitution compatibility?

A: Substitution compatibility is determined by SPDT circuit configuration, On-On switch function, 10A AC current rating at 120V, and 800mA DC current rating at 115V. The LSXN3K meets all these specifications identically.

Q: Are there packaging differences between the main part and substitute?

A: The LSXYNB3K was supplied with standard packaging, while the LSXN3K is available in bulk packaging. Both components are identical in electrical and mechanical function.

Q: Do both components meet the same compliance standards?

A: Both the LSXYNB3K and LSXN3K are RoHS Compliant with Moisture Sensitivity Level 1 (Unlimited). Compliance certifications are equivalent.

Q: What is the significance of the product status difference?

A: The LSXYNB3K is designated as obsolete, indicating discontinued manufacturing and limited availability. The LSXN3K maintains active product status, ensuring ongoing supply and support from Honeywell Sensing and Productivity Solutions.

Q: Are the mechanical specifications identical between both parts?

A: Yes. Both components feature side rotary actuation without lever, chassis mount configuration, screw terminal termination, 46gfm operating force, 65° pretravel, 30° differential travel, and 20° overtravel.
