Key Parameters

Substitute Part Grouping Explanation

Substitution of the LCW012T13SDC is evaluated based on the following critical parameters that must align for functional compatibility:

Circuit Configuration & Function: Both the main part and substitute must maintain SPDT circuit topology with On-Momentary switching function to preserve system logic.

Voltage & Current Ratings: The substitute must support the 125V AC voltage requirement. Current rating must meet or exceed the 100mA specification to handle the electrical load without derating.

Mechanical Interface: Chassis mount configuration with straight lever actuator must be maintained. Operating position of 0.345" (8.8mm) establishes the mechanical envelope.

Termination Compatibility: The main part uses solder lug termination. Substitutes with different termination styles (such as quick connect) require circuit board redesign and are evaluated separately.

Environmental & Compliance: Operating temperature range, RoHS compliance, and electrical/mechanical life cycles must support the intended application requirements.

Parameter Comparison

Engineering Selection Recommendations

The LCS05060T05QDC qualifies as a functional substitute for the LCW012T13SDC based on matching circuit topology, voltage rating, and mechanical interface. The substitute provides superior current handling capability (6A versus 100mA), ensuring adequate margin for the application load. Both components maintain ROHS3 compliance and equivalent electrical life specifications.

The primary consideration for implementation is termination style. The LCW012T13SDC uses solder lug termination, while the LCS05060T05QDC employs quick connect terminals. Direct mechanical substitution without circuit board modification is not possible. Applications requiring solder lug termination must either source the LCW012T13SDC from remaining inventory or implement circuit board redesign to accommodate quick connect termination.

The LCS05060T05QDC is recommended for new designs and applications where circuit board modification is feasible, as it is in active production status and provides extended operating temperature range (-40°C to 125°C versus -40°C to 120°C).

Frequently Asked Questions (FAQ)

Q: Can the LCS05060T05QDC directly replace the LCW012T13SDC without modifications?

A: Direct mechanical substitution is not possible due to termination style differences. The LCW012T13SDC uses solder lug termination while the LCS05060T05QDC uses quick connect terminals. Circuit board redesign is required for implementation.

Q: Does the LCS05060T05QDC meet the current requirements of the LCW012T13SDC?

A: Yes. The LCS05060T05QDC is rated for 6A AC current, which exceeds the 100mA requirement of the LCW012T13SDC, providing adequate margin for the application.

Q: Are both components RoHS compliant?

A: Yes. Both the LCW012T13SDC and LCS05060T05QDC are ROHS3 compliant.

Q: What is the operating temperature difference between these components?

A: The LCW012T13SDC operates from -40°C to 120°C, while the LCS05060T05QDC operates from -40°C to 125°C. The substitute provides a 5°C extended upper temperature limit.

Q: Why is the LCW012T13SDC classified as obsolete?

A: The LCW012T13SDC is no longer in active production. The LCS05060T05QDC represents the active production alternative from C&K for SPDT snap-action switch applications.

Q: Are the mechanical dimensions compatible between these switches?

A: Yes. Both components share the same operating position of 0.345" (8.8mm) and use identical chassis mount configuration with straight lever actuators, ensuring mechanical envelope compatibility.
