Key Parameters

Substitute Part Grouping Explanation

The LCA10150T09SC qualifies as a direct substitute based on the following critical parameters that determine functional equivalence:

Circuit configuration (SPDT), switch function (On-Mom), current rating (10A AC), voltage rating (125V AC), actuator type (lever, straight), mounting type (chassis mount), and termination style (solder lug) are identical between the main part and substitute. Both components operate across the same temperature range (-40°C to 125°C) and maintain equivalent electrical and mechanical life ratings (10,000 and 300,000 cycles respectively).

The LCA10150T09SC is an active product within the same LCA series, providing continuity for applications currently using the obsolete LCA10A140LS2SC. Both components are manufactured by C&K and comply with RoHS and REACH requirements.

Parameter Comparison

Engineering Selection Recommendations

The LCA10150T09SC is the designated substitute for the obsolete LCA10A140LS2SC. Both components meet identical electrical and mechanical specifications, ensuring functional compatibility in existing applications. The substitute maintains RoHS compliance with ROHS3 certification, exceeding the original RoHS Compliant status. Both parts are REACH unaffected and classified under ECCN EAR99.

Selection of the LCA10150T09SC eliminates obsolescence risk while preserving all critical performance parameters. The active product status ensures long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the LCA10150T09SC directly replace the LCA10A140LS2SC in existing designs?

A: Yes. Both components share identical circuit configuration (SPDT), switch function (On-Mom), current rating (10A AC), voltage rating (125V AC), actuator type (lever, straight), mounting type (chassis mount), and termination style (solder lug). Operating temperature ranges and life cycle ratings are equivalent.

Q: What is the primary reason for substitution?

A: The LCA10A140LS2SC is classified as obsolete. The LCA10150T09SC is an active product within the same LCA series, providing equivalent functionality with assured long-term availability.

Q: Are there packaging differences between these parts?

A: The LCA10A140LS2SC is supplied with standard packaging, while the LCA10150T09SC is supplied in bulk packaging. This distinction affects procurement and inventory management but does not impact electrical or mechanical performance.

Q: Do both parts meet current compliance standards?

A: Yes. Both components are RoHS compliant and REACH unaffected. The LCA10150T09SC carries ROHS3 certification, representing current compliance standards.

Q: Are there differences in operating characteristics?

A: The LCA10150T09SC provides additional mechanical specification data (operating force, release force, pretravel, differential travel, and overtravel) compared to the main part. These parameters define actuator behavior but do not affect circuit-level compatibility for applications designed around the LCA10A140LS2SC specifications.
