LSYLB6C Equivalent & Substitute Parts Reference

Part Overview

The LSYLB6C is a snap action DPDT (double pole double throw) switch manufactured by Honeywell Sensing and Productivity Solutions. This component is designed for chassis mount applications with side rotary actuation and plug-in termination. The switch is rated for 10A AC at 120V and 800mA DC at 115V, featuring sequence action operation with an on-momentary switch function.

The LSYLB6C is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LSYLB6C is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must be DPDT (DB/DM)
• Switch function must be On-Momentary
• Current rating must support minimum 10A AC and 800mA DC
• Voltage ratings must meet or exceed 120V AC and 115V DC

Mechanical Compatibility Requirements:

• Actuator type must be Side Rotary - No Lever
• Mounting type must be Chassis Mount
• Termination style must be Plug In
• Operating force must be 46gfm
• Travel specifications (pretravel 15°, differential travel 5°, overtravel 48°) must match

Environmental & Compliance Requirements:

• Operating temperature range must encompass the application requirements
• RoHS compliance status must be maintained
• Moisture sensitivity level must be compatible with storage and handling conditions

Substitute parts are grouped based on identical electrical and mechanical parameters. Parts meeting all criteria above are considered direct functional equivalents.

Parameter Comparison

Engineering Selection Recommendations

LSL2C as Primary Substitute:

The LSL2C is a direct functional equivalent to the LSYLB6C across all critical electrical and mechanical parameters. Both components share identical circuit configuration, current and voltage ratings, actuator type, mounting configuration, and termination style. The LSL2C is manufactured by the same supplier (Honeywell Sensing and Productivity Solutions) within the same HDLS series.

Key Consideration - Operating Temperature Range:

The LSL2C operates over a temperature range of -12°C to 121°C, compared to the LSYLB6C range of -40°C to 121°C. The substitute part has a narrower lower temperature limit. Applications requiring operation below -12°C must evaluate whether the reduced low-temperature specification is acceptable for the intended use case.

Compliance and Availability:

Both parts maintain RoHS compliance and MSL Level 1 (Unlimited) moisture sensitivity rating. The LSL2C is currently in active production status with confirmed inventory availability (1133 pieces), whereas the LSYLB6C is obsolete. The LSL2C is the recommended path for new designs and ongoing supply requirements.

Frequently Asked Questions (FAQ)

Q: Can LSL2C directly replace LSYLB6C in existing applications?

A: LSL2C is electrically and mechanically equivalent to LSYLB6C across all specified parameters. Direct replacement is possible provided the application operating temperature does not fall below -12°C. If the system requires operation at temperatures below -12°C, the narrower temperature range of LSL2C must be evaluated against application requirements.

Q: What are the key differences between LSYLB6C and LSL2C?

A: The primary difference is product status: LSYLB6C is obsolete while LSL2C is active production. The operating temperature range differs: LSYLB6C operates from -40°C to 121°C, while LSL2C operates from -12°C to 121°C. All other electrical, mechanical, and compliance parameters are identical.

Q: Are there any packaging or termination differences?

A: Both parts use identical plug-in termination style and chassis mount configuration. No packaging or termination modifications are required for substitution.

Q: Does LSL2C maintain the same RoHS and moisture sensitivity compliance?

A: Yes. LSL2C is RoHS compliant and rated at MSL Level 1 (Unlimited), identical to LSYLB6C specifications.

Q: Why is LSYLB6C obsolete?

A: Product obsolescence is determined by the manufacturer. LSL2C represents the active equivalent within the HDLS series and is the recommended component for current and future applications.

Q: What should be verified before implementing LSL2C as a substitute?

A: Confirm that the application operating temperature range falls within -12°C to 121°C. Verify that the plug-in termination and chassis mount configuration are compatible with existing PCB or panel layouts. Confirm that the 10A AC / 800mA DC current ratings and 120V AC / 115V DC voltage ratings meet circuit requirements.
