LCW012T00SDC Equivalent & Substitute Parts

Part Overview

The LCW012T00SDC is a snap-action SPDT switch manufactured by C&K, designed for chassis mount applications with solder lug termination. This component operates at 125V AC with a 100mA current rating and provides IP67 ingress protection. The product is currently obsolete, making identification of suitable substitute components essential for ongoing maintenance, repair, and redesign applications where this switch is specified in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LCW012T00SDC is determined by the following critical parameters:

Electrical Compatibility:

• Circuit configuration must remain SPDT
• Voltage rating must support 125V AC minimum
• Current rating must support 100mA minimum

Mechanical Compatibility:

• Actuator type must be lever with straight configuration
• Mounting type must be chassis mount
• Operating position and travel characteristics must be compatible with existing mechanical interfaces

Environmental & Compliance:

• Ingress protection must maintain IP67 rating
• Operating temperature range must encompass -40°C to 120°C
• RoHS compliance status must be maintained

The LCS052T00WA20CC qualifies as a substitute based on these parameters, though with noted differences in termination style and current capacity.

Parameter Comparison

Engineering Selection Recommendations

The LCS052T00WA20CC serves as an active substitute for the obsolete LCW012T00SDC. Both components maintain identical SPDT circuit configuration, 125V AC voltage rating, and IP67 ingress protection. The substitute provides superior current handling capacity at 5A versus the original 100mA specification, ensuring compatibility with applications requiring the original component's current level.

The primary design consideration is termination style: the original uses solder lug termination while the substitute employs wire leads. This difference requires evaluation of the existing circuit board or assembly interface. The substitute's upper operating temperature limit of 105°C versus the original 120°C represents a minor reduction in thermal headroom but remains suitable for most industrial applications within the -40°C to 105°C range.

Both components maintain equivalent mechanical characteristics with identical 0.345" operating position and comparable operating force specifications (100gf original versus 98gf substitute). RoHS compliance is maintained across both versions, supporting environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the LCS052T00WA20CC directly replace the LCW012T00SDC in existing designs?

A: Electrical and mechanical compatibility is confirmed. The primary consideration is termination style: the substitute uses wire leads instead of solder lugs. If the original design incorporates solder lug connections, mechanical adaptation or circuit board modification may be required.

Q: What is the significance of the current rating difference between 100mA and 5A?

A: The substitute's higher current rating (5A) provides additional capacity beyond the original specification. This does not create incompatibility; the substitute can safely operate at the original 100mA current level. Applications requiring higher current switching benefit from the increased rating.

Q: Does the operating temperature range difference affect substitution?

A: The substitute operates to 105°C versus the original 120°C. For applications requiring operation above 105°C, the substitute is not suitable. For applications within -40°C to 105°C, the substitute provides equivalent performance.

Q: Are both components RoHS compliant?

A: Yes. The original LCW012T00SDC is RoHS3 compliant, and the substitute LCS052T00WA20CC is RoHS compliant, meeting environmental and regulatory requirements.

Q: What packaging considerations apply to the substitute?

A: The LCS052T00WA20CC is supplied in tray packaging. Verify compatibility with existing component handling and assembly processes if the original used different packaging.
