C&K U21T2PCLE Toggle Switch DPDT 5A 120V Equivalent & Substitute Parts

Part Overview

The C&K U21T2PCLE is a panel-mount toggle switch with DPDT (Double Pole Double Throw) configuration, rated for 5A at 120V AC and 28V DC. This component belongs to the C&K 7000 series and features a flat anti-rotation actuator with epoxy sealed PC pin terminations. The U21T2PCLE is classified as obsolete, making identification of active equivalent parts essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the U21T2PCLE is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: DPDT only
• Switch Function: On-On operation
• Current Rating: 5A (AC/DC)
• Voltage Ratings: 120V AC and 28V DC minimum
• Mounting Type: Panel Mount with matching mechanical interface
• Actuator Specifications: Flat Anti-Rotation type, 15.49mm length
• Termination: PC Pin configuration
• Panel Interface: Circular 11.91mm diameter cutout with 15/32-32 bushing thread
• Operating Temperature: -30°C to 85°C range
• Electrical Life: 100,000 cycles minimum

The U21T2PCRE qualifies as a direct substitute based on complete alignment with all specified electrical and mechanical parameters. The primary distinction is product status: U21T2PCRE is active production, whereas U21T2PCLE is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The U21T2PCRE is the direct substitute for the obsolete U21T2PCLE. Both components share identical electrical ratings, mechanical interfaces, and operational specifications. Selection between these parts is determined by availability and compliance requirements:

U21T2PCRE (Recommended for New Designs and Replenishment)

• Active production status ensures long-term availability
• RoHS Compliant certification
• REACH Affected status requires compliance verification for specific applications
• Preferred for new system implementations and component replenishment

U21T2PCLE (Legacy Systems Only)

• Obsolete status limits future availability
• RoHS3 Compliant certification
• REACH Unaffected status
• Suitable only for existing system maintenance where stock remains available

Both parts maintain identical electrical performance, mechanical fit, and environmental operating parameters. Component selection should prioritize the active U21T2PCRE for all new applications and ongoing procurement.

Frequently Asked Questions (FAQ)

Q: Can U21T2PCRE directly replace U21T2PCLE in existing assemblies? A: Yes. Both components are mechanically and electrically identical. The panel cutout dimensions, bushing thread specifications, actuator geometry, and electrical ratings are equivalent. No circuit modifications or mechanical rework is required.

Q: What is the difference between RoHS3 Compliant and RoHS Compliant? A: RoHS3 represents the third iteration of the Restriction of Hazardous Substances directive. Both designations indicate compliance with hazardous substance restrictions, though RoHS3 reflects the most current regulatory framework. Both parts meet hazardous substance limitations.

Q: Does REACH Affected status impact component selection? A: REACH Affected status indicates the component is subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. Compliance verification is required based on specific application and end-use requirements. This does not preclude component use but requires regulatory assessment.

Q: Are the panel mounting interfaces identical? A: Yes. Both components feature a circular 11.91mm diameter panel cutout with 15/32-32 bushing thread. Mechanical installation is identical with no panel modification required.

Q: What is the electrical life expectancy? A: Both components are rated for 100,000 electrical cycles under specified operating conditions (5A at 120V AC or 28V DC, -30°C to 85°C operating temperature range).

Q: Can these switches be used in DC applications? A: Yes. Both components are rated for 5A at 28V DC, making them suitable for DC circuit applications within the specified voltage and current limits.
