LSYRC5KP-FP Equivalent & Substitute Parts

Part Overview

The LSYRC5KP-FP is a snap action SPDT switch manufactured by Honeywell Sensing and Productivity Solutions, designed for chassis mount applications with cable lead termination. This switch operates at 10A AC (120V) and 800mA DC (115V) with IP67 ingress protection, making it suitable for industrial control and automation environments. The product is Active status with full RoHS compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical ratings, mechanical configurations, and environmental specifications align with the original design requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LSYRC5KP-FP are identified based on strict equivalence of the following critical parameters:

Electrical Equivalence:

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

Mechanical Equivalence:

• Actuator type: Side Rotary - No Lever
• Mounting type: Chassis Mount
• Termination style: Cable Leads
• Cable length: 12'

Environmental Equivalence:

• Ingress protection: IP67 - Dust Tight, Waterproof
• Operating temperature range compatibility
• RoHS compliance status

The LSYAC3KP-FP qualifies as a substitute part because it maintains identical electrical ratings, circuit configuration, mechanical mounting, and environmental protection specifications. Variations in operating force (19gfm vs. 46gfm) and operating temperature range (-1°C ~ 105°C vs. -12°C ~ 105°C) do not disqualify substitution when the application requirements fall within the overlapping operational envelope.

Parameter Comparison

Engineering Selection Recommendations

Both LSYRC5KP-FP and LSYAC3KP-FP are Active status products with full RoHS compliance and identical MSL ratings. Selection between these parts is determined by application-specific operating force requirements and temperature envelope constraints.

LSYRC5KP-FP is specified when the application requires an operating force of 19gfm and operates within the temperature range of -1°C to 105°C.

LSYAC3KP-FP is specified when the application requires an operating force of 46gfm or when extended low-temperature operation down to -12°C is necessary, while maintaining the upper temperature limit of 105°C.

Both parts maintain identical electrical performance (10A AC at 120V, 800mA DC at 115V), mechanical configuration (SPDT On-Mom, side rotary actuator, chassis mount), and environmental protection (IP67). The choice between these substitutes depends solely on whether the higher operating force of the LSYAC3KP-FP and its extended low-temperature capability align with the specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can LSYAC3KP-FP replace LSYRC5KP-FP in all applications?

A: LSYAC3KP-FP can replace LSYRC5KP-FP when the application operates within the overlapping temperature range (-1°C to 105°C) and when the higher operating force of 46gfm is acceptable. If the application specifically requires the lower operating force of 19gfm, LSYRC5KP-FP must be used.

Q: What is the difference in operating force between these two parts?

A: LSYRC5KP-FP has an operating force of 19gfm, while LSYAC3KP-FP has an operating force of 46gfm. This difference affects the actuation effort required to engage the switch.

Q: Are the electrical ratings identical between LSYRC5KP-FP and LSYAC3KP-FP?

A: Yes. Both parts are rated for 10A AC at 120V and 800mA DC at 115V with identical SPDT (DB/DM) circuit configuration and On-Mom switch function.

Q: What is the temperature operating range for each part?

A: LSYRC5KP-FP operates from -1°C to 105°C. LSYAC3KP-FP operates from -12°C to 105°C, providing extended low-temperature capability.

Q: Are both parts RoHS compliant?

A: Yes. Both LSYRC5KP-FP and LSYAC3KP-FP are RoHS compliant with MSL rating of 1 (Unlimited).

Q: Do these parts have identical mechanical mounting?

A: Yes. Both parts feature chassis mount configuration with side rotary actuator (no lever), cable lead termination, and 12-foot cable length.

Q: What ingress protection rating do these switches provide?

A: Both LSYRC5KP-FP and LSYAC3KP-FP provide IP67 protection, classified as dust tight and waterproof.
