LSXH4L Snap Action Switch - Equivalent & Substitute Parts

Part Overview

The LSXH4L is a DPDT snap action switch manufactured by Honeywell Sensing and Productivity Solutions, designed for chassis mount applications with screw terminal connections. This switch is rated for 10A AC at 120V and 800mA DC at 115V, featuring an explosion-proof design with side rotary actuator without lever.

The LSXH4L carries an obsolete product status. Identifying equivalent 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 LSXH4L is based on strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• DPDT circuit configuration (DB/DM)
• On-Mom switch function
• 10A AC current rating at 120V AC
• 800mA DC current rating at 115V DC

Mechanical Equivalence Requirements:

• Side rotary actuator without lever
• Chassis mount configuration
• Screw terminal termination

Environmental & Compliance Requirements:

• Explosion-proof design
• Operating temperature range -1°C to 121°C
• RoHS compliance
• MSL 1 rating

The LSXR4L meets all these criteria and qualifies as a direct substitute for the obsolete LSXH4L. Both parts share identical electrical ratings, mechanical mounting characteristics, and environmental specifications. The primary distinction is product status: LSXH4L is obsolete while LSXR4L maintains active production status.

Parameter Comparison

Engineering Selection Recommendations

The LSXR4L is the qualified substitute for the obsolete LSXH4L based on the following engineering criteria:

Electrical Compatibility: Both parts maintain identical current and voltage ratings across AC and DC specifications. The DPDT circuit configuration and On-Mom function are preserved, ensuring functional equivalence in control applications.

Mechanical Compatibility: Chassis mount configuration, screw terminal termination, and side rotary actuator design are identical between both parts. Physical installation and wiring procedures remain unchanged.

Environmental & Compliance Alignment: Both parts carry RoHS compliance certification, MSL 1 rating, and identical operating temperature ranges. Explosion-proof design specifications are maintained.

Operational Differences: The LSXR4L exhibits different pretravel (15° versus 9°), differential travel (7° versus 4°), and overtravel (60° versus 66°) characteristics. These mechanical travel parameters do not affect electrical functionality or circuit compatibility but may influence actuation feel and response characteristics in specific mechanical applications.

Product Status Advantage: The LSXR4L maintains active production status with documented inventory availability (881 pcs), whereas the LSXH4L is obsolete. Selection of LSXR4L ensures long-term supply chain continuity and support.

Frequently Asked Questions (FAQ)

Q: Can LSXR4L directly replace LSXH4L in existing applications?

A: Yes. Both parts share identical electrical ratings (10A AC at 120V, 800mA DC at 115V), circuit configuration (DPDT), switch function (On-Mom), mounting type (chassis mount), and termination style (screw terminal). Electrical and mechanical installation compatibility is confirmed.

Q: What are the differences between LSXH4L and LSXR4L?

A: The primary difference is product status: LSXH4L is obsolete while LSXR4L is active production. Secondary differences exist in mechanical travel parameters: LSXR4L has 15° pretravel (versus 9°), 7° differential travel (versus 4°), and 60° overtravel (versus 66°). These travel differences do not affect electrical performance or circuit compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both LSXH4L and LSXR4L carry RoHS compliance certification and MSL 1 (unlimited) moisture sensitivity rating.

Q: What is the inventory status for each part?

A: LSXH4L has 1022 pcs available as new original stock but carries obsolete status. LSXR4L has 881 pcs available as new original stock with active product status.

Q: Do the mechanical travel differences affect circuit switching?

A: No. Pretravel, differential travel, and overtravel parameters affect the mechanical actuation characteristics and user feel but do not alter electrical switching behavior, contact closure timing, or circuit performance.

Q: What is the operating temperature range for both parts?

A: Both LSXH4L and LSXR4L operate across -1°C to 121°C, ensuring compatibility across standard industrial temperature environments.

Q: Are both parts explosion-proof?

A: Yes. Both parts feature explosion-proof design as specified in their product documentation.
