C&K 7205J1V9LE2 Rocker Switch DPDT 5A 120V - Equivalent & Substitute Parts

Part Overview

The C&K 7205J1V9LE2 is a through-hole mounted rocker switch with DPDT (Double Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This switch features a momentary-off-momentary (Mom-Off-Mom) function with a concave black actuator and epoxy sealed PC pin terminals. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7205J1V9LE2 is determined by strict equivalence across the following critical parameters:

• Circuit configuration (DPDT)
• Switch function (Mom-Off-Mom)
• Current rating (5A AC/DC)
• Voltage ratings (120V AC, 28V DC)
• Mounting type (Through Hole)
• Actuator type and color (Concave, Black)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)
• Electrical life rating (40,000 Cycles)
• Approval certifications (cULus)

The C&K 7205J1V9RE2 meets all these criteria and qualifies as a direct functional equivalent. The primary distinction is product status: the 7205J1V9RE2 is active production, whereas the 7205J1V9LE2 is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7205J1V9RE2 is the direct functional equivalent for the obsolete 7205J1V9LE2. Both parts share identical electrical specifications, mechanical configuration, and performance ratings within the C&K 7000 series.

For new designs or component replacement in active systems, the 7205J1V9RE2 is the appropriate selection due to its active production status and availability. The substitute part maintains full compatibility with existing circuit designs and PCB layouts that accommodate the 7205J1V9LE2.

Compliance considerations: The 7205J1V9RE2 is RoHS Compliant and REACH Affected, whereas the original part is RoHS non-compliant and REACH Unaffected. Organizations subject to RoHS or REACH regulations should prioritize the 7205J1V9RE2 for new procurement and system updates.

Frequently Asked Questions (FAQ)

Q: Can the 7205J1V9RE2 be used as a direct replacement for the 7205J1V9LE2 in existing assemblies?

A: Yes. Both parts are electrically and mechanically identical across all functional parameters: DPDT circuit, 5A/120V AC rating, Mom-Off-Mom function, through-hole mounting, and PC pin termination. PCB layouts and circuit designs require no modification.

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

A: The primary difference is product status. The 7205J1V9LE2 is obsolete; the 7205J1V9RE2 is in active production. Secondary differences include RoHS and REACH compliance status. The 7205J1V9RE2 provides panel cutout dimensions (17.96mm x 10.62mm), whereas this specification is not provided for the original part.

Q: Are there any compatibility concerns with panel mounting?

A: Both parts use identical through-hole mounting and actuator configurations. The 7205J1V9RE2 specifies rectangular panel cutout dimensions of 17.96mm x 10.62mm. If the original assembly was designed for the 7205J1V9LE2, this dimension should be verified against the actual panel opening to ensure proper fit.

Q: Which part should be selected for new designs?

A: The C&K 7205J1V9RE2 should be selected for all new designs. It is in active production, carries current compliance certifications, and is functionally equivalent to the obsolete 7205J1V9LE2.

Q: Are there electrical performance differences between these parts?

A: No. Both parts are rated for 5A at 120V AC and 28V DC, operate across -30°C to 85°C, and provide 40,000 electrical life cycles. Electrical performance is identical.
