Substitute Part Grouping Explanation

Substitution of the LSXA3K1-1C is determined by strict equivalence across the following critical parameters:

Electrical Compatibility:

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

Mechanical Compatibility:

• Actuator type: Side rotary roller mechanism
• Mounting configuration: Chassis mount
• Termination: Screw terminal connections
• Operating force: 46gfm
• Travel specifications: 15° pretravel, 5° differential travel, 60° overtravel

Environmental & Compliance:

• Operating temperature range: -12°C to 121°C
• RoHS compliance status
• Moisture sensitivity level: 1 (Unlimited)

The LSA3K-1D meets all these criteria and is identified as a direct functional equivalent. Both parts share identical electrical ratings, mechanical actuation characteristics, and environmental specifications. The primary distinction is product status: LSA3K-1D is active, whereas LSXA3K1-1C is obsolete.
