LSYWC1A Snap Action Switch Equivalent & Substitute Parts

Part Overview

The LSYWC1A 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 an adjustable side plunger actuator and plug-in termination style. The LSYWC1A is currently listed as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LSYWC1A is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

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

Mechanical Compatibility Parameters:

• Actuator type: Adjustable Side Plunger
• Mounting type: Chassis Mount
• Termination style: Plug In
• Operating force: 2720gf
• Travel specifications: Pretravel 0.100" (2.5mm), Differential Travel 0.025" (0.6mm), Overtravel 0.190" (4.8mm)

Compliance Parameters:

• RoHS Compliant status
• Moisture Sensitivity Level 1

The LSYWB1A meets all specified electrical and mechanical parameters, making it a direct functional equivalent for the obsolete LSYWC1A.

Parameter Comparison

Engineering Selection Recommendations

The LSYWB1A is the direct substitute for the obsolete LSYWC1A. Both components are manufactured by Honeywell Sensing and Productivity Solutions within the HDLS series and share identical electrical ratings, mechanical specifications, and compliance certifications.

Selection Basis:

The LSYWB1A maintains active product status, ensuring ongoing availability and manufacturer support. Both parts are RoHS Compliant with Moisture Sensitivity Level 1, meeting environmental and reliability standards.

Operating Temperature Consideration:

The LSYWC1A operates across -12°C to 121°C, while the LSYWB1A operates across -29°C to 93°C. The operating temperature ranges overlap from -12°C to 93°C. Applications requiring operation below -12°C or above 93°C must evaluate specific thermal requirements against the LSYWB1A's specified range.

Packaging Difference:

The LSYWC1A is supplied in standard packaging, while the LSYWB1A is supplied in bulk packaging. This distinction affects procurement and inventory management but does not impact functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can the LSYWB1A directly replace the LSYWC1A in existing applications?

A: The LSYWB1A is electrically and mechanically equivalent to the LSYWC1A across all specified parameters. Direct replacement is supported for applications operating within the overlapping temperature range of -12°C to 93°C.

Q: What is the primary difference between LSYWC1A and LSYWB1A?

A: The LSYWC1A is obsolete, while the LSYWB1A is an active product. The LSYWB1A offers a narrower operating temperature range (-29°C to 93°C versus -12°C to 121°C) and is supplied in bulk packaging rather than standard packaging.

Q: Are both parts from the same manufacturer?

A: Yes. Both the LSYWC1A and LSYWB1A are manufactured by Honeywell Sensing and Productivity Solutions and belong to the HDLS series.

Q: Do the electrical ratings differ between these parts?

A: No. Both parts are rated for 10A AC at 120V and 800mA DC at 115V with identical SPDT (DB/DM) circuit configuration and On-Mom switch function.

Q: What are the mechanical specifications that must match for substitution?

A: Substitution requires identical actuator type (Adjustable Side Plunger), mounting type (Chassis Mount), termination style (Plug In), operating force (2720gf), and travel specifications (Pretravel 0.100", Differential Travel 0.025", Overtravel 0.190"). Both parts meet these requirements.

Q: Is the LSYWB1A RoHS Compliant?

A: Yes. The LSYWB1A is RoHS Compliant with Moisture Sensitivity Level 1 (Unlimited), matching the compliance status of the LSYWC1A.

Q: How does packaging affect the substitution decision?

A: Packaging type (standard versus bulk) does not affect functional equivalence. The selection between packaging options depends on procurement volume and inventory management requirements.
