U21SCWAGE Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The U21SCWAGE is an active-status toggle switch manufactured by C&K, featuring DPDT (Double Pole Double Throw) circuitry with On-On switching function. This panel-mount, right-angle switch is rated for 5A at 120V AC and 28V DC, with IP67 ingress protection and epoxy-sealed terminals. The part is actively produced and stocked, with 950 units available in tray packaging. Equivalent and substitute parts are identified when component availability changes, procurement lead times extend, or inventory constraints require alternative sourcing while maintaining functional compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the U21SCWAGE is determined by strict alignment of the following parameters:

• Circuit Configuration: Must be DPDT
• Switch Function: Must be On-On
• Mounting Type: Must be Panel Mount, Right Angle
• Panel Cutout Dimensions: Must be Circular - 6.35mm Dia
• Bushing Thread: Must be 1/4-40
• Termination Style: Must be PC Pin
• Operating Temperature Range: Must support -30°C to 85°C minimum
• RoHS Compliance: Must be ROHS3 Compliant

The substitute part 100DP1T3B1M6REH (E-Switch) meets all mandatory mechanical and circuit configuration requirements. However, electrical ratings differ: the substitute is rated for 0.4VA at 20V AC/DC, compared to the main part's 5A at 120V AC and 28V DC. Substitution is valid only in applications where the lower electrical ratings are acceptable.

Parameter Comparison

Engineering Selection Recommendations

Both the U21SCWAGE and 100DP1T3B1M6REH are active-status products with ROHS3 compliance. Selection between these parts is determined by application electrical requirements:

• U21SCWAGE: Select for applications requiring 5A switching capacity at 120V AC or 28V DC, with 100,000-cycle electrical life specification.
• 100DP1T3B1M6REH: Select only for low-power applications rated at 0.4VA maximum, 20V AC/DC, where the 40,000-cycle electrical life is acceptable.

Both parts share identical mechanical interfaces (6.35mm panel cutout, 1/4-40 bushing thread, PC pin termination) and support the full -30°C to 85°C operating temperature range. The actuator length difference (10.67mm versus 13.97mm) must be evaluated for panel depth clearance in the target application.

Frequently Asked Questions (FAQ)

Q: Can 100DP1T3B1M6REH replace U21SCWAGE in all applications?

A: No. The substitute part is rated for 0.4VA at 20V maximum, while the main part supports 5A at 120V AC and 28V DC. Substitution is valid only in applications where the electrical load does not exceed the substitute's ratings.

Q: Are the panel mounting interfaces identical?

A: Yes. Both parts feature a 6.35mm circular panel cutout and 1/4-40 bushing thread, enabling direct mechanical interchange in panel-mount installations.

Q: What is the difference in actuator length, and does it matter?

A: The U21SCWAGE has a 10.67mm actuator length, while the 100DP1T3B1M6REH has a 13.97mm actuator length. This 3.3mm difference must be evaluated for available panel depth and operator access clearance in the target installation.

Q: Do both parts meet RoHS requirements?

A: Yes. Both U21SCWAGE and 100DP1T3B1M6REH are ROHS3 compliant.

Q: What is the electrical life difference between these parts?

A: The U21SCWAGE is rated for 100,000 switching cycles, while the 100DP1T3B1M6REH is rated for 40,000 cycles. Applications requiring extended cycle life should prioritize the U21SCWAGE.

Q: Are the termination styles compatible?

A: Yes. Both parts use PC pin termination, enabling direct connection to standard PCB footprints designed for this termination type.
