C&K 8168LHCKI2 Pushbutton Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 8168LHCKI2 is a panel-mount pushbutton switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 0.4VA at 20V AC/DC. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. Substitute parts must maintain identical electrical ratings, mechanical mounting compatibility, and circuit functionality to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 8168LHCKI2 are identified based on strict equivalence across the following critical parameters:

• Circuit Configuration: SPDT topology must be maintained
• Electrical Ratings: Current (0.4VA) and voltage (20V AC/DC) must be identical or higher
• Mounting Interface: Panel mount, rear configuration with 6.35mm circular cutout
• Termination Style: PC pin termination for PCB compatibility
• Switch Function: On-momentary operation
• Operating Temperature: -30°C to +65°C range
• Electrical Life: 50,000 cycles minimum

The C&K 8168LHCPI2 qualifies as a direct substitute based on complete alignment with these parameters. While classified in a different series (8020 versus 8060), the electrical and mechanical specifications are functionally identical, enabling seamless replacement in applications currently using the 8168LHCKI2.

Frequently Asked Questions (FAQ)

Q: Can the 8168LHCPI2 directly replace the 8168LHCKI2 in existing designs?

A: Yes. The substitute part maintains identical electrical ratings (0.4VA, 20V AC/DC), circuit configuration (SPDT), mounting interface (6.35mm panel cutout, rear mount), and termination style (PC pin). No design modifications are required.

Q: What is the difference between the 8060 and 8020 series designations?

A: Series designation reflects internal C&K product line organization. The functional and electrical specifications are equivalent across both series for these specific part numbers.

Q: Are there any compliance differences between the two parts?

A: The 8168LHCPI2 carries active RoHS compliance and REACH affected status, reflecting current regulatory requirements. The 8168LHCKI2 is RoHS3 compliant and REACH unaffected. Both parts meet EAR99 export classification.

Q: What is the panel cutout requirement for installation?

A: Both parts require a circular panel cutout of 6.35mm diameter for rear-mount panel installation.

Q: Is the 8168LHCPI2 suitable for the same operating temperature range?

A: Yes. Both parts operate across the identical temperature range of -30°C to +65°C.

Q: What is the electrical life expectancy?

A: Both the main part and substitute are rated for 50,000 electrical cycles.
