LSXD3K Snap Action Switch - Equivalent & Substitute Parts

Part Overview

The LSXD3K is a snap action switch manufactured by Honeywell Sensing and Productivity Solutions, classified as a SPDT (Single Pole Double Throw) switch with chassis mount configuration. This component is rated for 10A AC at 120V and 800mA DC at 115V, featuring a roller plunger actuator and screw terminal connections. The LSXD3K is designated as obsolete, making identification of functionally equivalent substitute parts essential for system maintenance, repair, and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LSXD3K is determined by strict equivalence across the following critical parameters:

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

Mechanical Parameters: Actuator type (Roller Plunger), mounting configuration (Chassis Mount), and termination style (Screw Terminal) must match exactly.

Dimensional Parameters: Operating position (2.700" / 68.6mm), pretravel (0.070" / 1.78mm), differential travel (0.015" / 0.38mm), and overtravel (0.190" / 4.8mm) establish the physical interface requirements.

Environmental Parameters: Operating force (1814gf), operating temperature range, and explosion proof rating define the functional envelope.

Compliance Parameters: RoHS compliance and MSL rating ensure regulatory and handling compatibility.

The LSXYDB3K meets all substitution criteria for the LSXD3K based on these parameters.

Engineering Selection Recommendations

The LSXYDB3K is a direct functional equivalent to the LSXD3K across all critical electrical, mechanical, and dimensional parameters. The substitute part maintains identical circuit configuration, current and voltage ratings, actuator type, mounting configuration, and termination style.

The LSXYDB3K offers an extended operating temperature range (-29°C to 93°C compared to -12°C to 93°C), providing enhanced low-temperature performance capability. This extended range does not compromise compatibility with applications designed for the LSXD3K.

The LSXYDB3K holds active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain RoHS compliance and identical MSL ratings, supporting equivalent handling and environmental requirements.

For applications currently utilizing the obsolete LSXD3K, the LSXYDB3K provides direct substitution without circuit redesign or mechanical modification.

Frequently Asked Questions (FAQ)

Q: Can the LSXYDB3K replace the LSXD3K in existing applications?

A: Yes. The LSXYDB3K is electrically and mechanically equivalent to the LSXD3K. All critical parameters including circuit configuration, current ratings, voltage ratings, actuator type, mounting configuration, and termination style are identical. No circuit modifications or mechanical changes are required.

Q: What is the difference between the LSXD3K and LSXYDB3K?

A: The primary differences are product status and operating temperature range. The LSXD3K is obsolete with an operating range of -12°C to 93°C. The LSXYDB3K is an active product with an extended low-temperature operating range of -29°C to 93°C. All other electrical and mechanical specifications are identical.

Q: Are the screw terminal connections compatible between these parts?

A: Yes. Both the LSXD3K and LSXYDB3K use identical screw terminal termination style, ensuring direct compatibility with existing wiring and connector interfaces.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the LSXD3K and LSXYDB3K are RoHS compliant with MSL rating of 1 (Unlimited), meeting identical regulatory and handling requirements.

Q: What is the significance of the extended temperature range in the LSXYDB3K?

A: The LSXYDB3K operates from -29°C to 93°C, compared to the LSXD3K range of -12°C to 93°C. This extended low-temperature capability provides additional operational margin for applications exposed to lower ambient temperatures. For applications within the original -12°C to 93°C range, both parts perform identically.

Q: Is the LSXYDB3K available in the same packaging as the LSXD3K?

A: Both parts use identical chassis mount configuration and screw terminal termination. The physical form factor and mounting interface are equivalent.
