Honeywell LSP1F Snap Action Switch - Equivalent & Substitute Parts

Part Overview

The Honeywell LSP1F is a snap action switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 10A AC at 120V and 800mA DC at 115V. This component features a side rotary actuator without lever and chassis mount termination via plug-in connection. The LSP1F is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system maintenance and component procurement.

The primary reason for identifying substitutes is the obsolete product status of the LSP1F. Active equivalent models ensure supply chain continuity and support for legacy equipment requiring this switch specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LSP1F is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

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

Mechanical Parameters:

• Actuator type: Side Rotary - No Lever
• Mounting type: Chassis Mount
• Termination style: Plug In
• Operating force: 46gfm
• Travel specifications: Pretravel 9°, Differential Travel 3°, Overtravel 66°

Environmental & Compliance Parameters:

• Operating temperature range: -12°C to 121°C
• RoHS compliance status
• Moisture sensitivity level: 1 (Unlimited)

The LSP1A qualifies as a direct substitute based on identical values across all critical electrical, mechanical, and environmental parameters. The primary distinction is product status (LSP1A is active) and packaging format (LSP1A supplied in bulk).

Parameter Comparison

Engineering Selection Recommendations

The LSP1A is a direct functional and electrical equivalent to the obsolete LSP1F. Selection of LSP1A is supported by the following factors:

Product Status: LSP1A maintains active product status with Honeywell Sensing and Productivity Solutions, ensuring ongoing availability and manufacturer support. The LSP1F obsolete classification necessitates transition to an active equivalent.

Compliance Certification: Both parts maintain identical RoHS compliance status and moisture sensitivity level (MSL 1 - Unlimited), confirming regulatory equivalence for applications requiring environmental compliance documentation.

Electrical and Mechanical Specifications: All critical parameters—circuit configuration, current and voltage ratings, actuator type, mounting configuration, termination style, and mechanical travel specifications—are identical between LSP1F and LSP1A.

Inventory Availability: LSP1A is available in higher inventory quantities (1113 pcs) compared to LSP1F (739 pcs), supporting supply chain continuity for new procurements and system maintenance.

The only operational difference is packaging format: LSP1A is supplied in bulk packaging, whereas LSP1F uses standard packaging. This distinction does not affect electrical or mechanical performance and is a procurement consideration only.

Frequently Asked Questions (FAQ)

Q: Can LSP1A be used as a direct replacement for LSP1F in existing equipment?

A: Yes. LSP1A is electrically and mechanically equivalent to LSP1F across all specified parameters. The identical circuit configuration (SPDT), current ratings (10A AC / 800mA DC), voltage ratings (120V AC / 115V DC), actuator type (side rotary without lever), mounting type (chassis mount), and termination style (plug-in) confirm direct substitutability. Operating force, travel specifications, and temperature range are also identical.

Q: What is the difference between LSP1F and LSP1A?

A: The primary differences are product status and packaging. LSP1F is classified as obsolete, while LSP1A is active. LSP1A is supplied in bulk packaging format. All electrical, mechanical, and environmental specifications are identical.

Q: Are there any compliance or certification differences between these parts?

A: No. Both LSP1F and LSP1A maintain identical RoHS compliance status and moisture sensitivity level (MSL 1 - Unlimited). Regulatory and environmental compliance certifications are equivalent.

Q: Does packaging format affect performance or compatibility?

A: No. Packaging format (standard versus bulk) is a procurement and logistics consideration only. It does not affect electrical performance, mechanical operation, or physical compatibility with chassis mount installations.

Q: Why is LSP1F classified as obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. LSP1A represents the active equivalent within the HDLS series, ensuring continued availability for applications requiring this switch specification.

Q: What parameters must match for a part to be considered a substitute for LSP1F?

A: Critical matching parameters include circuit configuration (SPDT DB/DM), switch function (On-Mom), current rating (10A AC / 800mA DC), voltage rating (120V AC / 115V DC), actuator type (side rotary without lever), mounting type (chassis mount), termination style (plug-in), operating force (46gfm), travel specifications (9° pretravel, 3° differential travel, 66° overtravel), and operating temperature range (-12°C to 121°C).
