Substitute Part Grouping Explanation

Substitution eligibility for the LSXA4L3-2C is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

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

Mechanical Equivalence Requirements:

• Actuator type: Side Rotary with Adjustable Roller
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Operating force: 46gfm
• Pretravel: 15°
• Differential travel: 7°
• Overtravel: 60°

Environmental & Compliance Requirements:

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

The LSXA4L-2C meets all substitution criteria as an active product within the same LSX series, maintaining identical electrical specifications, mechanical characteristics, and environmental ratings while offering improved supply availability.

Parameter Comparison

Engineering Selection Recommendations

The LSXA4L-2C is the direct equivalent substitute for the obsolete LSXA4L3-2C. Both parts are manufactured by Honeywell Sensing and Productivity Solutions within the LSX series and maintain identical electrical, mechanical, and environmental specifications. The LSXA4L-2C is currently in active production status with confirmed inventory availability (1094 pieces), whereas the LSXA4L3-2C is obsolete with limited remaining stock (846 pieces).

From a compliance perspective, both parts carry identical RoHS certification and moisture sensitivity ratings, ensuring regulatory equivalence in applications subject to environmental standards. The LSXA4L-2C is supplied in bulk packaging, which may differ from the original part's packaging configuration but does not affect functional or mechanical compatibility.

Selection of the LSXA4L-2C eliminates obsolescence risk while maintaining full electrical and mechanical interchangeability. No circuit redesign, mechanical modification, or functional requalification is required for substitution.

Frequently Asked Questions (FAQ)
