C&K 7105J2CLE2 Rocker Switch SPDT 5A 120V - Equivalent & Substitute Parts

Part Overview

The C&K 7105J2CLE2 is a through-hole rocker switch with SPDT (Single Pole Double Throw) configuration, rated for 5A at 120V AC and 28V DC. The switch features a momentary-off-momentary (Mom-Off-Mom) function with a black paddle actuator and epoxy sealed PC pin terminals. This part is currently obsolete, making identification of active equivalent models essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

The C&K 7105J2CRE2 qualifies as a direct substitute for the 7105J2CLE2 based on the following critical parameters:

• Circuit Configuration: Both parts are SPDT with identical Mom-Off-Mom switching function
• Electrical Ratings: Both rated for 5A (AC/DC), 120V AC, and 28V DC
• Mechanical Interface: Both feature through-hole mounting with PC pin termination and black paddle actuators
• Operating Conditions: Identical temperature range (-30°C to 85°C) and electrical life (40,000 cycles)
• Regulatory Compliance: Both carry cULus approval and meet RoHS requirements
• Base Product Family: Both belong to the C&K 7000 series with the same base product number (7105J)

The primary distinction is product status: the 7105J2CLE2 is obsolete while the 7105J2CRE2 is active, with improved availability (953 units in stock versus 652 units).

Parameter Comparison

Engineering Selection Recommendations

The C&K 7105J2CRE2 is the appropriate selection for applications currently using or specifying the 7105J2CLE2. The substitute part maintains full electrical and mechanical compatibility across all critical parameters. The transition from ROHS3 to RoHS compliance in the substitute part reflects current regulatory standards and does not impact functional performance. The active product status of the 7105J2CRE2 ensures long-term availability and supply chain stability, addressing the obsolescence of the original part.

Frequently Asked Questions (FAQ)

Q: Are the 7105J2CLE2 and 7105J2CRE2 electrically interchangeable?

A: Yes. Both parts share identical electrical specifications: SPDT configuration, 5A (AC/DC) current rating, 120V AC and 28V DC voltage ratings, and 40,000-cycle electrical life. They are direct electrical equivalents.

Q: Will the 7105J2CRE2 fit the same PCB footprint as the 7105J2CLE2?

A: Yes. Both parts use through-hole mounting with PC pin termination and identical actuator geometry (black paddle). The panel cutout dimensions for the 7105J2CRE2 are specified as rectangular 17.96mm x 10.62mm, which represents the standard mechanical interface for this product family.

Q: What is the difference between ROHS3 and RoHS compliance?

A: ROHS3 refers to the third iteration of the Restriction of Hazardous Substances directive. The 7105J2CRE2 carries current RoHS compliance, which supersedes ROHS3 and reflects updated regulatory requirements. Both designations confirm the absence of restricted hazardous substances.

Q: Is the 7105J2CRE2 suitable for the same operating temperature range?

A: Yes. Both parts operate across the identical temperature range of -30°C to 85°C, ensuring equivalent thermal performance in all applications.

Q: Why is the 7105J2CLE2 listed as obsolete?

A: The 7105J2CLE2 has been discontinued by C&K. The 7105J2CRE2 represents the active equivalent within the 7000 series product line and is the recommended replacement for new designs and ongoing procurement.
