Key Parameters

Substitute Part Grouping Explanation

Substitution of the LSYAB3KE-FP is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

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

Mechanical Compatibility Parameters:

• Actuator type: Side Rotary - No Lever
• Mounting type: Chassis Mount
• Termination style: Cable Leads
• Operating force: 46gfm
• Pretravel: 15°
• Differential travel: 5°
• Overtravel: 60°

Environmental & Compliance Parameters:

• Ingress protection: IP67
• RoHS compliance
• MSL rating: 1

The LSA1AC substitute part maintains identical electrical and mechanical specifications across all critical parameters, ensuring direct functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The LSA1AC is a direct functional equivalent to the LSYAB3KE-FP. Both components are manufactured by Honeywell Sensing and Productivity Solutions within the HDLS series and maintain identical electrical, mechanical, and environmental specifications.

Selection Basis:

The LSA1AC substitute is appropriate for applications currently using the LSYAB3KE-FP because:

• All critical electrical parameters match: 10A AC at 120V, 800mA DC at 115V
• All mechanical parameters match: Side rotary actuator, 46gfm operating force, identical travel specifications
• Environmental protection is equivalent: IP67 ingress protection rating
• Compliance certifications are identical: RoHS compliant, MSL 1 rating
• The LSA1AC maintains active product status, ensuring ongoing availability and support

The primary distinction is product status: LSYAB3KE-FP is obsolete while LSA1AC is active. This makes LSA1AC the appropriate selection for new designs, repairs, and component replenishment.

Frequently Asked Questions (FAQ)

Q: Can LSA1AC directly replace LSYAB3KE-FP in existing applications?

A: Yes. The LSA1AC maintains identical electrical ratings (10A AC at 120V, 800mA DC at 115V), circuit configuration (SPDT), switch function (On-Momentary), mechanical specifications (46gfm operating force, 15° pretravel, 5° differential travel, 60° overtravel), mounting type (chassis mount), termination style (cable leads), and ingress protection (IP67). No circuit modifications are required.

Q: What is the difference between LSYAB3KE-FP and LSA1AC?

A: The components are electrically and mechanically identical. The primary difference is product status: LSYAB3KE-FP is classified as obsolete, while LSA1AC is active. Additionally, LSYAB3KE-FP is packaged with cable leads in a specific configuration, while LSA1AC is available in bulk packaging. Both are manufactured by Honeywell Sensing and Productivity Solutions.

Q: Are there any temperature operating range differences?

A: Yes. LSYAB3KE-FP operates from -40°C to 121°C, while LSA1AC operates from -12°C to 60°C. Applications requiring operation below -12°C or above 60°C must verify compatibility with the LSA1AC temperature range.

Q: What packaging options are available?

A: LSYAB3KE-FP is supplied with cable leads as standard termination. LSA1AC is available in bulk packaging. Both maintain identical electrical and mechanical specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both LSYAB3KE-FP and LSA1AC are RoHS compliant with MSL rating 1 (unlimited moisture sensitivity level).

Q: Why is LSYAB3KE-FP obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. LSA1AC is the active equivalent and is the recommended selection for ongoing component sourcing.
