LSXP3K-1C Equivalent & Substitute Parts

Part Overview

The LSXP3K-1C is a snap action SPDT switch manufactured by Honeywell Sensing and Productivity Solutions. This switch features a side rotary roller actuator, chassis mount configuration, and screw terminal termination, rated for 10A AC at 120V and 800mA DC at 115V. The product is classified as obsolete, necessitating identification of active equivalent alternatives to maintain design continuity and ensure supply chain availability for new production and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LSXP3K-1C is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• 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, Roller
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Operating temperature range: -12°C to 121°C
• RoHS compliance status

Allowable Variation Parameters:

• Pretravel, differential travel, and overtravel specifications may vary within mechanical design tolerances
• Product status may differ (active vs. obsolete)
• Packaging configuration may differ

The LSXA3K-1C qualifies as a direct substitute based on identical electrical ratings, circuit topology, actuator configuration, and mounting specifications across all mandatory parameters.

Parameter Comparison

Engineering Selection Recommendations

The LSXA3K-1C is the qualified substitute for the obsolete LSXP3K-1C based on complete electrical and mechanical parameter equivalence. Selection criteria are as follows:

Primary Recommendation: LSXA3K-1C

This part maintains identical electrical performance across all rated parameters: 10A AC at 120V and 800mA DC at 115V. The SPDT circuit topology, On-Mom switch function, side rotary roller actuator, chassis mount configuration, and screw terminal termination are functionally equivalent. Both parts operate across the identical temperature range of -12°C to 121°C and carry RoHS compliance certification with MSL 1 rating.

The LSXA3K-1C holds active product status, ensuring ongoing manufacturer support, availability, and supply chain continuity. This status distinction is the primary driver for substitution, as the LSXP3K-1C is classified as obsolete.

Mechanical travel specifications (pretravel, differential travel, and overtravel) exhibit minor variations. These variations fall within acceptable mechanical design tolerances for snap action switch operation and do not affect electrical performance or circuit compatibility.

Both parts share identical export classification (ECCN EAR99) and tariff coding (HTSUS 8536.50.9055), ensuring regulatory compliance equivalence.

Frequently Asked Questions (FAQ)

Q: Can the LSXA3K-1C directly replace the LSXP3K-1C in existing designs?

A: Yes. The LSXA3K-1C is electrically and mechanically equivalent across all critical parameters. Identical current ratings (10A AC, 800mA DC), voltage ratings (120V AC, 115V DC), circuit configuration (SPDT), actuator type (side rotary roller), mounting type (chassis mount), and termination style (screw terminal) ensure direct functional compatibility.

Q: What are the differences between these two parts?

A: The primary differences are product status and mechanical travel specifications. The LSXP3K-1C is obsolete, while the LSXA3K-1C is active. Pretravel differs by 6° (9° vs. 15°), differential travel by 2° (3° vs. 5°), and overtravel by 6° (66° vs. 60°). These mechanical variations do not affect electrical performance or circuit operation.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical RoHS compliance status, MSL 1 rating, ECCN classification (EAR99), and HTSUS tariff code (8536.50.9055).

Q: What is the packaging difference?

A: The LSXP3K-1C packaging is not specified in available documentation. The LSXA3K-1C is supplied in bulk packaging. Confirm packaging requirements with procurement specifications for your application.

Q: Why is the LSXP3K-1C obsolete?

A: Product obsolescence is determined by the manufacturer. The LSXA3K-1C represents the active equivalent within the LSX series and should be used for all new designs and field replacements.

Q: Are the operating force specifications identical?

A: Yes. Both parts specify 46gfm operating force, ensuring equivalent actuator response characteristics.

Q: Can I use the LSXA3K-1C in applications originally designed for the LSXP3K-1C?

A: Yes. Electrical ratings, circuit topology, and mechanical mounting are identical. The minor variations in travel specifications do not compromise functional compatibility in standard snap action switch applications.
