LSYWC1F Equivalent & Substitute Parts Reference

Part Overview

The LSYWC1F is a snap action SPDT (Single Pole Double Throw) switch manufactured by Honeywell Sensing and Productivity Solutions, designed for chassis mount applications with plug-in termination. This component operates at 10A AC (120V) and 800mA DC (115V) with an adjustable side plunger actuator. The LSYWC1F is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LSYWC1F 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
• Pretravel: 0.100" (2.5mm)
• Differential travel: 0.025" (0.6mm)
• Overtravel: 0.190" (4.8mm)

Environmental & Compliance Parameters:

• RoHS compliance status
• Moisture sensitivity level (MSL)
• Operating temperature range (within acceptable limits for the application)

The LSYWB1A meets all critical electrical and mechanical parameters required for direct substitution of the LSYWC1F.

Parameter Comparison

Engineering Selection Recommendations

The LSYWB1A is the direct equivalent substitute for the obsolete LSYWC1F. Both components share identical electrical ratings, mechanical specifications, and functional characteristics across all critical parameters. The LSYWB1A is currently in active production status, ensuring ongoing availability for component replacement and new system designs.

The operating temperature range differs between the two parts. The LSYWC1F operates from -12°C to 121°C, while the LSYWB1A operates from -29°C to 93°C. Selection between these ranges depends on the specific thermal environment of the application. For applications requiring operation above 93°C, the LSYWC1F specifications must be maintained if available through inventory channels. For applications requiring operation below -12°C, the LSYWB1A provides extended low-temperature capability.

Both components are RoHS compliant and carry MSL Level 1 (Unlimited) moisture sensitivity classification, meeting modern environmental and reliability standards.

Frequently Asked Questions (FAQ)

Q: Can LSYWB1A directly replace LSYWC1F in existing designs?

A: Yes. The LSYWB1A is electrically and mechanically equivalent to the LSYWC1F across all critical parameters: circuit configuration (SPDT), current rating (10A AC / 800mA DC), voltage rating (120V AC / 115V DC), actuator type (adjustable side plunger), mounting type (chassis mount), and termination style (plug-in). Direct substitution is supported for applications operating within the LSYWB1A temperature range of -29°C to 93°C.

Q: What is the difference in operating temperature ranges?

A: The LSYWC1F operates from -12°C to 121°C, while the LSYWB1A operates from -29°C to 93°C. The LSYWB1A extends the lower temperature limit by 17°C but reduces the upper temperature limit by 28°C. Application thermal requirements determine which part is appropriate.

Q: Are there packaging differences between LSYWC1F and LSYWB1A?

A: The LSYWC1F packaging is not specified in available documentation. The LSYWB1A is supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility for chassis mount applications.

Q: Why is LSYWC1F classified as obsolete?

A: The LSYWC1F is no longer in active production. The LSYWB1A serves as the current production equivalent, offering identical functional specifications with active manufacturing support.

Q: Are both parts RoHS compliant?

A: Yes. Both LSYWC1F and LSYWB1A are RoHS compliant and carry MSL Level 1 (Unlimited) moisture sensitivity classification.

Q: What is the base product number for LSYWB1A?

A: The base product number for LSYWB1A is LSYWB1, indicating the product family designation within the HDLS series.
