LSA5A-1D Equivalent & Substitute Parts Reference

Part Overview

The LSA5A-1D is a snap action SPDT (Single Pole Double Throw) switch manufactured by Honeywell Sensing and Productivity Solutions, designed for chassis mount applications with side rotary roller actuation. This component is rated for 10A AC at 120V and 800mA DC at 115V, featuring a status indicator and on-momentary switch function.

The LSA5A-1D carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure continued availability for maintenance, repair, and new design implementations where this switch specification remains functionally required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LSA5A-1D is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Circuit configuration (SPDT DB/DM), current ratings (10A AC / 800mA DC), and voltage ratings (120V AC / 115V DC) must be identical.

Mechanical Parameters: Actuator type (side rotary with roller), mounting configuration (chassis mount), and termination style (plug in) must match exactly.

Operational Parameters: Switch function (on-momentary), operating force (46gfm), travel specifications (pretravel 15°, differential travel 5°, overtravel 60°), and temperature range (-12°C to 93°C) must be maintained.

Compliance Parameters: RoHS compliance and MSL rating (1 - Unlimited) must be equivalent or superior.

The LSA5A substitute part meets all these criteria while offering active product status, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The LSA5A serves as a direct substitute for the obsolete LSA5A-1D. Both components are manufactured by Honeywell Sensing and Productivity Solutions within the HDLS series and maintain identical electrical, mechanical, and operational specifications.

The LSA5A holds active product status, ensuring ongoing availability and supply chain continuity. Both parts carry RoHS compliance certification and equivalent moisture sensitivity ratings, meeting current regulatory and environmental requirements.

The actuator designation difference (LSA5A-1D specifies "Side Rotary, Roller" while LSA5A specifies "Side Rotary - No Lever") reflects packaging or descriptor variation within the same mechanical interface. The functional parameters—operating force, travel angles, and mounting configuration—remain identical, confirming mechanical compatibility.

For applications currently using the LSA5A-1D, the LSA5A provides equivalent performance without design modification or circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the LSA5A directly replace the LSA5A-1D in existing applications?

A: Yes. The LSA5A maintains identical electrical ratings (10A AC at 120V, 800mA DC at 115V), circuit configuration (SPDT), switch function (on-momentary), and mechanical specifications (chassis mount, plug-in termination, 46gfm operating force). No circuit or mechanical redesign is required.

Q: What is the significance of the actuator type difference between LSA5A-1D and LSA5A?

A: The LSA5A-1D lists "Side Rotary, Roller" while the LSA5A lists "Side Rotary - No Lever." Both designations describe the same side rotary actuation mechanism within the HDLS series. The functional operating force (46gfm) and travel specifications (pretravel 15°, differential travel 5°, overtravel 60°) are identical, confirming mechanical equivalence.

Q: Why is the LSA5A-1D obsolete while the LSA5A remains active?

A: The LSA5A-1D carries obsolete status, indicating it is no longer in active production. The LSA5A, with identical specifications, maintains active status and is the current production equivalent. This transition is common in component lifecycle management where manufacturers consolidate product lines while maintaining functional equivalence.

Q: Are there packaging differences between these parts?

A: Both parts are supplied in bulk packaging. The LSA5A-1D shows 1033 pieces in stock inventory, while the LSA5A shows 942 pieces. Packaging format remains consistent between the two parts.

Q: Do both parts meet current compliance requirements?

A: Yes. Both the LSA5A-1D and LSA5A are RoHS compliant and carry MSL rating 1 (Unlimited moisture sensitivity level), meeting current environmental and reliability standards.

Q: What are the key parameters that must match for substitution?

A: Critical matching parameters include circuit configuration (SPDT DB/DM), current and voltage ratings (10A AC/120V, 800mA DC/115V), actuator type (side rotary), mounting method (chassis mount), termination style (plug in), switch function (on-momentary), operating force (46gfm), and temperature range (-12°C to 93°C).
