C&K U21T2PCME Toggle Switch DPDT 5A 120V Equivalent & Substitute Parts

Part Overview

The C&K U21T2PCME 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 flat anti-rotation actuator, epoxy sealed terminals, and is designed for On-On switching applications. The U21T2PCME is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system maintenance and new design implementations where this component is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the U21T2PCME are identified based on strict electrical and mechanical parameter matching within the C&K 7000 series. The following parameters determine substitution eligibility:

• Circuit configuration: DPDT
• Switch function: On-On
• Current rating: 5A (AC/DC)
• Voltage ratings: 120V AC / 28V DC
• Mounting type: Panel Mount
• Actuator type: Flat Anti-Rotation
• Actuator length: 15.49mm
• Termination style: PC Pin
• Panel cutout dimensions: Circular - 11.91mm Dia
• Bushing thread: 15/32-32
• Operating temperature range: -30°C to 85°C
• Electrical life: 100,000 Cycles

Parts meeting all these parameters are classified as direct equivalents and may be used interchangeably in applications where the U21T2PCME is specified.

Parameter Comparison

Engineering Selection Recommendations

The C&K U21T2PCSE is a direct functional equivalent to the obsolete U21T2PCME. Both parts share identical electrical ratings, mechanical dimensions, and operational characteristics. The primary distinction is product status: the U21T2PCME is obsolete while the U21T2PCSE is active and currently in production.

For new designs and replacement applications, the U21T2PCSE is the appropriate selection. Both parts maintain RoHS compliance and are classified under ECCN EAR99. The U21T2PCSE carries REACH Affected status compared to the U21T2PCME's REACH Unaffected designation; however, this does not affect functional interchangeability in standard applications.

Frequently Asked Questions (FAQ)

Q: Can the U21T2PCSE directly replace the U21T2PCME in existing assemblies?

A: Yes. The U21T2PCSE is mechanically and electrically identical to the U21T2PCME. Panel cutout dimensions, bushing thread specifications, actuator geometry, and electrical ratings are identical, enabling direct substitution without circuit or mechanical redesign.

Q: What is the significance of the product status difference between these parts?

A: The U21T2PCME is classified as obsolete, indicating it is no longer manufactured. The U21T2PCSE is active and in current production. For new procurements and long-term supply chain planning, the U21T2PCSE should be specified.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS compliant and classified as EAR99. The U21T2PCSE is REACH Affected while the U21T2PCME is REACH Unaffected. This distinction relates to regulatory substance tracking and does not impact electrical or mechanical performance.

Q: What are the critical parameters for confirming substitution eligibility?

A: Substitution eligibility is determined by matching: circuit configuration (DPDT), switch function (On-On), current rating (5A AC/DC), voltage ratings (120V AC / 28V DC), mounting type (Panel Mount), panel cutout dimensions (11.91mm circular), bushing thread (15/32-32), and operating temperature range (-30°C to 85°C).

Q: Are there any inventory or lead time considerations?

A: The U21T2PCME has 1089 pieces in stock as new original inventory. The U21T2PCSE has 984 pieces in stock. Availability should be confirmed with the supplier for specific procurement timelines.
