Key Parameters

Substitute Part Grouping Explanation

Substitution of the LSYAC3KY-FP is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

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

Mechanical Compatibility Parameters:

• Actuator type: Side Rotary - No Lever
• Mounting type: Chassis Mount
• Termination style: Cable Leads with 12-foot cable length
• Ingress protection: IP67 rating

Environmental & Operational Parameters:

• Operating temperature range: -12°C to 105°C
• Operating force: 46gfm
• Pretravel: 15°
• Differential travel: 5°
• Overtravel: 60°

Substitute parts must match all parameters listed above. Packaging differences do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The LSYAC3KP-FP is a direct functional equivalent to the LSYAC3KY-FP. Both components are manufactured by Honeywell Sensing and Productivity Solutions and share identical electrical, mechanical, and environmental specifications across all critical parameters.

The primary distinction between these parts is product status: the LSYAC3KY-FP is classified as obsolete, while the LSYAC3KP-FP maintains active product status. This status difference reflects manufacturing availability and supply chain considerations rather than technical capability differences.

Both parts are RoHS compliant and carry identical ECCN (EAR99) and HTSUS (8536.50.9055) classifications, confirming regulatory equivalence for procurement and deployment purposes.

Packaging differences (standard versus bulk) do not affect component performance or compatibility in applications. Selection between these parts should be based on availability, supply chain requirements, and procurement volume considerations.

Frequently Asked Questions (FAQ)

Q: Can LSYAC3KP-FP replace LSYAC3KY-FP in existing applications?

A: Yes. The LSYAC3KP-FP is electrically and mechanically equivalent to the LSYAC3KY-FP across all specified parameters, including circuit configuration, current and voltage ratings, actuator type, mounting configuration, and environmental operating range.

Q: What is the significance of the "obsolete" status for LSYAC3KY-FP?

A: Obsolete status indicates that the LSYAC3KY-FP is no longer in active production. The LSYAC3KP-FP, with active product status, represents the current manufacturing equivalent and is the recommended selection for new procurement and system replacements.

Q: Are there packaging differences between these parts?

A: Yes. The LSYAC3KY-FP is supplied in standard packaging, while the LSYAC3KP-FP is supplied in bulk packaging. Packaging differences do not affect electrical or mechanical performance and are determined by procurement volume and supply chain requirements.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the LSYAC3KY-FP and LSYAC3KP-FP are RoHS compliant, carry identical ECCN and HTSUS classifications, and share the same moisture sensitivity level (MSL 1 - Unlimited).

Q: What parameters must match for a part to be considered a substitute?

A: Substitute parts must match all electrical parameters (circuit configuration, current and voltage ratings, switch function), mechanical parameters (actuator type, mounting type, termination style, cable length), and environmental parameters (operating temperature range, operating force, travel specifications, ingress protection rating).

Q: Is the LSYAC3KP-FP available in inventory?

A: Yes. The LSYAC3KP-FP is available with 768 pieces in new original stock, providing immediate availability for procurement and deployment.
