C&K 7105J2V3LE2 Rocker Switch SPDT 5A 120V - Equivalent & Substitute Parts

Part Overview

The C&K 7105J2V3LE2 is a rocker switch with SPDT (Single Pole Double Throw) configuration rated for 5A at 120V AC/DC operation. This through-hole mounted switch features a momentary-off-momentary (Mom-Off-Mom) function with a black paddle actuator and epoxy sealed PC pin terminals. The part is currently obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The C&K 7105J2V3RE2 qualifies as a direct substitute for the 7105J2V3LE2 based on the following critical parameters:

• Circuit Configuration: Both parts maintain SPDT topology
• Switch Function: Identical Mom-Off-Mom operation
• Current and Voltage Ratings: Both rated 5A (AC/DC), 120V AC, 28V DC
• Mounting and Termination: Through-hole mounting with PC pin terminals
• Actuator Specification: Black paddle actuator on both parts
• Operating Temperature: Identical -30°C to 85°C range
• Electrical Life: Both rated 40,000 cycles
• Regulatory Compliance: Both carry cULus approval

The primary distinction is product status: the 7105J2V3LE2 is obsolete while the 7105J2V3RE2 is active, making the latter the appropriate selection for new designs and ongoing support.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7105J2V3RE2 is the appropriate selection for applications currently using or specifying the 7105J2V3LE2. The substitute part maintains full electrical and mechanical compatibility across all critical parameters while offering the advantage of active product status. This ensures continued availability, manufacturing support, and compliance with current regulatory standards. The transition from ROHS3 to RoHS compliance on the substitute part reflects current manufacturing practices and does not impact functional performance in the specified application envelope.

Frequently Asked Questions (FAQ)

Q: Are the 7105J2V3LE2 and 7105J2V3RE2 electrically interchangeable?

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

Q: What is the difference between these two part numbers?

A: The primary difference is product status. The 7105J2V3LE2 is obsolete, while the 7105J2V3RE2 is active. Both parts are mechanically and electrically identical in all specified parameters.

Q: Can I use the 7105J2V3RE2 as a drop-in replacement in existing designs?

A: Yes. The substitute part maintains identical through-hole mounting, PC pin termination, panel cutout dimensions (17.96mm x 10.62mm), and all electrical specifications. No design modifications are required.

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

A: Both parts carry cULus approval. The substitute part reflects current RoHS compliance standards while the original part was ROHS3 compliant. Both meet applicable regulatory requirements for their respective manufacturing periods.

Q: What is the mechanical life specification for these switches?

A: Mechanical life data is not provided in the technical specifications for either part. The electrical life rating is 40,000 cycles for both components.
