LSXYPB3K Snap Action Switch - Equivalent & Substitute Parts

Part Overview

The LSXYPB3K 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 LSXYPB3K is designated as obsolete, necessitating identification of active equivalent components for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete LSXYPB3K is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Circuit configuration: SPDT (DB/DM)
• Switch function: On-Momentary
• Current rating: 10A AC / 800mA DC
• Voltage rating: 120V AC / 115V DC

Mechanical Compatibility Parameters:

• Actuator type: Side Rotary - No Lever
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Operating force: 46gfm
• Travel specifications: Pretravel 9°, Differential Travel 3°, Overtravel 66°

Compliance Parameters:

• Manufacturer: Honeywell Sensing and Productivity Solutions
• Series: LSX
• RoHS compliance
• Explosion proof rating

The LSXP3K meets all specified electrical, mechanical, and compliance requirements for direct substitution. Both components share identical electrical ratings, mechanical specifications, and feature sets within the LSX series.

Parameter Comparison

Engineering Selection Recommendations

The LSXP3K is the direct equivalent substitute for the obsolete LSXYPB3K. Both components are manufactured by Honeywell Sensing and Productivity Solutions within the LSX series and share identical electrical ratings, mechanical specifications, and feature sets.

Selection Basis:

The LSXP3K maintains full compatibility across all critical parameters: SPDT circuit configuration, 10A AC / 800mA DC current ratings, 120V AC / 115V DC voltage ratings, side rotary actuation, chassis mount configuration, and screw terminal termination. Both components feature identical operating force (46gfm), travel characteristics (9° pretravel, 3° differential travel, 66° overtravel), and explosion proof rating.

The LSXP3K holds active product status with current manufacturing availability, whereas the LSXYPB3K is obsolete. Both components are RoHS compliant with MSL rating 1 (unlimited moisture sensitivity level).

Temperature Range Consideration:

The LSXP3K operating temperature range (-12°C to 121°C) is narrower at the lower limit compared to the LSXYPB3K (-40°C to 121°C). Applications requiring operation below -12°C must evaluate this specification difference against system requirements.

Frequently Asked Questions (FAQ)

Q: Can the LSXP3K directly replace the LSXYPB3K in existing applications?

A: The LSXP3K is electrically and mechanically equivalent to the LSXYPB3K across all specified parameters. Direct replacement is supported for applications operating within the LSXP3K temperature range of -12°C to 121°C. Applications requiring operation below -12°C require engineering evaluation.

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

A: Substitution compatibility is determined by: SPDT circuit configuration, On-Momentary switch function, 10A AC current rating, 800mA DC current rating, 120V AC voltage rating, and 115V DC voltage rating. The LSXP3K matches all these parameters.

Q: Are both components RoHS compliant?

A: Both the LSXYPB3K and LSXP3K are RoHS compliant with MSL rating 1 (unlimited moisture sensitivity level).

Q: What is the difference in operating temperature ranges?

A: The LSXYPB3K operates from -40°C to 121°C, while the LSXP3K operates from -12°C to 121°C. The LSXP3K has a narrower lower temperature limit. Applications requiring operation below -12°C must assess compatibility with system requirements.

Q: Are the mechanical specifications identical?

A: Yes. Both components feature identical actuator type (side rotary - no lever), mounting type (chassis mount), termination style (screw terminal), operating force (46gfm), pretravel (9°), differential travel (3°), and overtravel (66°).

Q: What is the product status difference?

A: The LSXYPB3K is obsolete, while the LSXP3K is active. The LSXP3K is currently manufactured and available for procurement.

Q: Do both components feature explosion proof rating?

A: Yes. Both the LSXYPB3K and LSXP3K are rated as explosion proof.
