C&K 7205TCWWLE Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7205TCWWLE is a panel-mount toggle switch with DPDT (Double Pole Double Throw) configuration rated for 5A at 120V AC and 28V DC. This switch features a Mom-Off-Mom (momentary-off-momentary) function with IP67 ingress protection and epoxy-sealed terminals for harsh environment applications. The 7205TCWWLE is classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 7205TCWWLE is determined by strict equivalence across the following critical parameters:

• Circuit configuration (DPDT)
• Switch function (Mom-Off-Mom)
• Current and voltage ratings (5A AC/DC, 120V AC, 28V DC)
• Mounting type and mechanical interface (Panel Mount, 11.91mm circular cutout, 15/32-32 bushing thread)
• Actuator specifications (Standard Round, 17.45mm length)
• Termination style (Wire Wrap)
• Environmental protection (IP67)
• Operating temperature range (-30°C to 85°C)
• Electrical life (40,000 cycles)

The C&K 7205TCWWRE meets all these criteria and serves as a direct substitute within the same 7000 series platform.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7205TCWWRE is the direct functional equivalent to the obsolete 7205TCWWLE. Both parts maintain identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: the 7205TCWWRE is active and currently in production, whereas the 7205TCWWLE is obsolete.

The 7205TCWWRE offers improved regulatory compliance, achieving RoHS compliance status compared to the non-compliant 7205TCWWLE. The substitute part is also REACH Affected, indicating current regulatory engagement. For applications requiring RoHS compliance or long-term supply chain stability, the 7205TCWWRE is the appropriate selection.

Both parts are mechanically and electrically interchangeable within panel-mount applications requiring DPDT momentary switching at 5A/120V AC or 5A/28V DC with IP67 environmental protection.

Frequently Asked Questions (FAQ)

Q: Can the 7205TCWWRE directly replace the 7205TCWWLE in existing assemblies?

A: Yes. The 7205TCWWRE is mechanically and electrically identical to the 7205TCWWLE. Panel cutout dimensions, bushing thread specifications, wire wrap termination, and all electrical ratings are equivalent. No mechanical or electrical modifications are required.

Q: What is the difference between the 7205TCWWLE and 7205TCWWRE?

A: The primary differences are product status and regulatory compliance. The 7205TCWWLE is obsolete and RoHS non-compliant. The 7205TCWWRE is active production and RoHS compliant. All functional and mechanical parameters are identical.

Q: Are there any compatibility concerns when substituting the 7205TCWWRE for the 7205TCWWLE?

A: No compatibility concerns exist. Both switches share identical circuit configuration (DPDT), switch function (Mom-Off-Mom), current/voltage ratings (5A AC/DC, 120V AC, 28V DC), mounting interface, and environmental specifications (IP67, -30°C to 85°C operating range).

Q: What does the Mom-Off-Mom function mean?

A: Mom-Off-Mom indicates momentary-off-momentary operation. The switch returns to the center off position when released from either direction, requiring continuous actuation to maintain a switched state.

Q: Is the 7205TCWWRE suitable for harsh environment applications?

A: Yes. The 7205TCWWRE maintains IP67 ingress protection (dust tight and waterproof) with epoxy-sealed terminals, making it suitable for harsh environment panel-mount applications within the specified operating temperature range of -30°C to 85°C.
