LSXYRB3K Equivalent & Substitute Parts Reference

Part Overview

The LSXYRB3K is a snap action switch manufactured by Honeywell Sensing and Productivity Solutions, configured as a Single Pole Double Throw (SPDT) device with chassis mount installation. This switch is rated for 10A AC at 120V and 800mA DC at 115V, featuring a side rotary actuator without lever and screw terminal connections. The device is classified as obsolete, necessitating identification of active equivalent components for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LSXYRB3K is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

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

Mechanical Parameters:

• Actuator type: Side Rotary - No Lever
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Operating force: 19gfm
• Pretravel: 15°
• Differential travel: 5°
• Overtravel: 60°

Environmental & Compliance Parameters:

• Features: Explosion Proof
• Operating temperature range compatibility
• RoHS compliance status
• Moisture sensitivity level

The LSXR3K qualifies as a direct substitute based on identical values across all critical electrical, mechanical, and environmental parameters. The primary distinction is product status: LSXYRB3K is obsolete while LSXR3K is active.

Parameter Comparison

Engineering Selection Recommendations

The LSXR3K is the direct equivalent substitute for the obsolete LSXYRB3K. Both components are manufactured by Honeywell Sensing and Productivity Solutions within the LSX series and maintain identical electrical, mechanical, and functional specifications.

Selection Basis:

1. Product Status: LSXR3K is active and available for procurement, whereas LSXYRB3K is obsolete. For new designs or system replacements, LSXR3K is the appropriate selection.

2. Electrical Equivalence: Both parts maintain identical current ratings (10A AC / 800mA DC), voltage ratings (120V AC / 115V DC), and circuit configuration (SPDT DB/DM).

3. Mechanical Compatibility: Identical actuator type, mounting configuration, termination style, and operating characteristics ensure direct mechanical substitution.

4. Compliance: Both components are RoHS compliant with MSL rating of 1 (Unlimited), meeting environmental and regulatory requirements.

5. Temperature Consideration: The LSXR3K operating temperature range (-1°C ~ 121°C) is narrower at the low end compared to LSXYRB3K (-29°C ~ 121°C). Applications requiring operation below -1°C must retain the original LSXYRB3K or identify alternative solutions.

6. Packaging: LSXR3K is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Frequently Asked Questions (FAQ)

Q: Can LSXR3K be used as a direct replacement for LSXYRB3K in existing assemblies?

A: Yes, LSXR3K is a direct substitute for LSXYRB3K in applications where the operating temperature does not fall below -1°C. All electrical, mechanical, and functional parameters are identical. Physical mounting and terminal connections are compatible.

Q: What is the primary difference between LSXYRB3K and LSXR3K?

A: The primary difference is product status: LSXYRB3K is obsolete while LSXR3K is active. Additionally, LSXR3K has a narrower low-temperature operating range (-1°C versus -29°C minimum). All other specifications are identical.

Q: Are there any electrical performance differences between these two parts?

A: No. Both parts maintain identical current ratings (10A AC / 800mA DC), voltage ratings (120V AC / 115V DC), circuit configuration (SPDT DB/DM), and switch function (On-Mom).

Q: What is the operating temperature limitation when substituting LSXR3K for LSXYRB3K?

A: LSXR3K is rated for -1°C to 121°C, whereas LSXYRB3K is rated for -29°C to 121°C. If your application requires operation below -1°C, LSXR3K is not suitable. Retain LSXYRB3K or identify an alternative component.

Q: Are both parts RoHS compliant?

A: Yes. Both LSXYRB3K and LSXR3K are RoHS compliant with MSL rating of 1 (Unlimited).

Q: What packaging is available for LSXR3K?

A: LSXR3K is supplied in bulk packaging. Confirm packaging requirements with your procurement department.

Q: Do these switches have identical mechanical life and electrical life ratings?

A: Mechanical life and electrical life data are not provided in the component specifications for either part.

Q: Are the screw terminal connections identical between both parts?

A: Yes. Both LSXYRB3K and LSXR3K use screw terminal termination style with identical specifications.
