LSYRC2B Equivalent & Substitute Parts Reference

Part Overview

The LSYRC2B is a snap action DPDT (double pole double throw) switch manufactured by Honeywell Sensing and Productivity Solutions, designed for chassis mount applications with plug-in termination. This component is rated for 10A AC at 120V and 800mA DC at 115V, featuring a side rotary actuator without lever. The LSYRC2B is classified as obsolete, making identification of functionally equivalent active alternatives essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution of the obsolete LSYRC2B is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

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

Mechanical Equivalence Criteria:

• Actuator type: Side Rotary - No Lever
• Mounting type: Chassis Mount
• Termination style: Plug In
• Operating force: 19gfm
• Pretravel: 15°
• Differential travel: 7°
• Overtravel: 60°

Environmental & Compliance Criteria:

• Operating temperature range: -1°C to 121°C
• RoHS compliance status
• Moisture sensitivity level: 1 (Unlimited)

The LSR6B meets all specified parameters and is classified as an active product, providing direct functional and mechanical compatibility with the LSYRC2B.

Parameter Comparison

Engineering Selection Recommendations

The LSR6B is the direct equivalent substitute for the obsolete LSYRC2B. Both components are manufactured by Honeywell Sensing and Productivity Solutions within the HDLS series and share identical electrical, mechanical, and environmental specifications. The LSR6B maintains active product status, ensuring ongoing availability and manufacturer support.

Both parts are RoHS compliant and carry MSL Level 1 (Unlimited) moisture sensitivity classification, indicating no special storage or handling requirements. The electrical performance parameters—10A AC at 120V and 800mA DC at 115V—are identical, as are all mechanical characteristics including the side rotary actuator, chassis mount configuration, and plug-in termination.

Selection of the LSR6B for replacement of LSYRC2B applications requires no design modifications, as all functional and physical parameters are equivalent.

Frequently Asked Questions (FAQ)
