Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LSA7L-4R is determined by strict equivalence across the following critical parameters:

Electrical Compatibility:

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

Mechanical Compatibility:

• Actuator type: Side Rotary, Adjustable Rod
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Operating force: 46gfm
• Travel specifications: Pretravel 15°, Differential Travel 7°, Overtravel 60°

Environmental & Compliance:

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

The LSA7L-4N meets all substitution criteria as it shares identical electrical ratings, mechanical specifications, actuator configuration, and environmental operating parameters with the LSA7L-4R. The primary distinction is product status: LSA7L-4N is active, whereas LSA7L-4R is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The LSA7L-4N is a direct functional equivalent to the LSA7L-4R. Both components are manufactured by Honeywell Sensing and Productivity Solutions within the HDLS series and share identical electrical, mechanical, and environmental specifications.

Selection Basis:

The LSA7L-4N is the appropriate substitute for the obsolete LSA7L-4R because it maintains active product status with Honeywell, ensuring ongoing availability and supply chain support. Both parts carry RoHS compliance certification and identical moisture sensitivity ratings, confirming regulatory and environmental compatibility.

All critical parameters—circuit configuration, current and voltage ratings, actuator mechanics, mounting configuration, termination style, and operating temperature range—are identical between the two parts. This equivalence ensures direct functional replacement without circuit redesign or mechanical modification.
