Substitute Part Grouping Explanation

Substitution of the LSXA4K-2J is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

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

Mechanical Equivalence Criteria:

• Actuator type: Side Rotary, Adjustable Roller
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Operating force: 46gfm
• Pretravel: 15°
• Differential travel: 5°
• Overtravel: 60°

Environmental & Compliance Criteria:

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

The LSXA3K-2C meets all specified equivalence criteria and is classified as an active product, making it a direct functional substitute for the obsolete LSXA4K-2J.

Parameter Comparison

Engineering Selection Recommendations

The LSXA3K-2C is the direct equivalent substitute for the obsolete LSXA4K-2J. Both components are manufactured by Honeywell Sensing and Productivity Solutions within the LSX series and share identical electrical, mechanical, and environmental specifications.

Selection Basis:

The LSXA3K-2C maintains full parameter equivalence across all critical specifications: SPDT circuit configuration, 10A AC / 800mA DC current ratings, 120V AC / 115V DC voltage ratings, side rotary adjustable roller actuation, chassis mount configuration, and screw terminal termination. Both components operate across the identical temperature range of -12°C to 121°C and carry RoHS compliance certification with MSL 1 rating.

The primary distinction is product status: the LSXA4K-2J is classified as obsolete, while the LSXA3K-2C is active. This status difference reflects manufacturing availability and supply chain support, with the LSXA3K-2C representing the current production equivalent.

For applications currently utilizing the LSXA4K-2J, direct substitution with the LSXA3K-2C is supported without modification to electrical or mechanical interfaces.
