Equivalent & Substitute Parts for Honeywell LSP5A Snap Action Switch

Part Overview

The Honeywell LSP5A is an SPDT snap action switch designed for chassis mount applications with a 10A AC rating at 120V. This switch features a side rotary actuator without lever, plug-in termination, and status indicator functionality. The LSP5A operates across a temperature range of -12°C to 121°C and is classified as Active product status with RoHS compliance.

Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable, while maintaining functional equivalence within specified electrical and mechanical parameters.

Substitute Part Grouping Explanation

The Omron D4A-1302N is identified as a direct substitute for the Honeywell LSP5A based on the following critical parameters:

Electrical Compatibility:

• Both parts maintain SPDT circuit configuration with On-Mom switch function
• Both rated for 10A AC operation
• AC voltage ratings are compatible (120V LSP5A vs. 125V D4A-1302N)
• Both feature status indicator functionality

Mechanical Compatibility:

• Both utilize side rotary actuator without lever
• Both are chassis mount configuration
• Both are RoHS compliant and Active product status
• Both operate within overlapping temperature ranges for standard industrial applications

Substitution Limitations: The D4A-1302N differs in termination style (screw terminal vs. plug-in), ingress protection rating (IP67 vs. unspecified), and DC current ratings. These differences must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Honeywell LSP5A): The LSP5A remains the primary choice for applications requiring plug-in termination, extended high-temperature operation to 121°C, and 800mA DC current capability. Both parts maintain Active product status with RoHS compliance, ensuring long-term availability and regulatory conformance.

Substitute Selection (Omron D4A-1302N): The D4A-1302N is suitable as a substitute when screw terminal connection is acceptable and environmental sealing (IP67) is beneficial. The substitute provides higher DC current rating (6A) and documented electrical/mechanical life cycles (1,000,000 electrical cycles, 50,000,000 mechanical cycles). Temperature operation is limited to 80°C maximum.

Compliance Status: Both parts are RoHS compliant with ECCN EAR99 classification and HTSUS code 8536.50.9055. The D4A-1302N includes REACH Unaffected status.

Frequently Asked Questions (FAQ)

Q: Can the Omron D4A-1302N directly replace the Honeywell LSP5A in all applications?

A: Direct replacement is limited by termination style differences (screw terminal vs. plug-in) and operating temperature range. The D4A-1302N maximum temperature of 80°C is lower than the LSP5A specification of 121°C. Application-specific requirements must be evaluated.

Q: What are the key electrical parameters that determine substitution compatibility?

A: Circuit configuration (SPDT), switch function (On-Mom), AC current rating (10A), and AC voltage rating (120V/125V) are the primary electrical parameters. Both parts meet these criteria. DC ratings differ significantly and must be evaluated for DC applications.

Q: How do the mechanical characteristics differ between these parts?

A: Operating force differs by 6gfm (46gfm vs. 40gfm). Pretravel, differential travel, and overtravel angles vary slightly. Both maintain side rotary actuator configuration without lever and chassis mount design.

Q: What is the significance of the IP67 rating on the D4A-1302N?

A: IP67 classification indicates dust-tight and waterproof performance. The LSP5A ingress protection rating is not specified. Applications requiring environmental sealing benefit from the D4A-1302N specification.

Q: Are both parts suitable for long-term procurement?

A: Both parts maintain Active product status. The D4A-1302N provides documented electrical life (1,000,000 cycles) and mechanical life (50,000,000 cycles) specifications, supporting reliability analysis for high-cycle applications.

Q: What packaging considerations apply to these parts?

A: Both parts are supplied in Bulk packaging. Inventory availability differs (819 pcs LSP5A vs. 971 pcs D4A-1302N). Moisture sensitivity level is 1 (Unlimited) for both parts.
