T201KV3KE Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The T201KV3KE is a panel-mount toggle switch manufactured by C&K with DPDT (Double Pole Double Throw) configuration and On-On switching function. This component is classified as obsolete and is no longer in active production. The switch is rated for 0.4VA at 20V AC/DC with a locking lever actuator and epoxy-sealed PC pin terminations.

Due to its obsolete status, locating replacement inventory from original sources becomes increasingly difficult. Direct substitutes with active product status and current manufacturing support are available to ensure design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

The T201KV3PE is a direct functional equivalent to the T201KV3KE. Substitution is valid based on the following criteria:

Electrical Parameters Match:

• Identical circuit configuration (DPDT)
• Identical switch function (On-On)
• Identical current rating (0.4VA AC/DC)
• Identical voltage ratings (20V AC and 20V DC)
• Identical electrical life specification (60,000 cycles)

Mechanical Parameters Match:

• Identical mounting type (Panel Mount)
• Identical actuator type (Locking Lever)
• Identical actuator length (16.26mm)
• Identical panel cutout dimensions (Circular - 6.35mm Dia)
• Identical bushing thread specification (1/4-40)

Environmental Parameters Match:

• Identical operating temperature range (-30°C ~ 85°C)
• Identical termination style (PC Pin)
• Identical actuator material (Brass, Chrome Plated)
• Identical feature set (Epoxy Sealed Terminals)

Key Differentiator: The T201KV3PE maintains active product status with current manufacturing support, whereas the T201KV3KE is obsolete. Both parts share the same base product number (T201K) and are fully interchangeable at the circuit and mechanical interface level.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Redesigns: The T201KV3PE is the appropriate selection. This part carries active product status with ongoing manufacturing support from C&K. It meets current RoHS3 compliance requirements and is subject to REACH regulations, ensuring alignment with modern regulatory frameworks.

For Existing Inventory Management: The T201KV3KE remains functionally equivalent for applications already in production. However, long-term supply continuity is not assured due to obsolete status. Transition planning to T201KV3PE is recommended for future production runs.

Compliance Considerations: Both parts satisfy RoHS requirements. The T201KV3PE provides enhanced compliance documentation through ROHS3 certification and REACH status tracking, which may be required for certain end-use applications or regional markets.

Packaging Compatibility: The T201KV3PE is supplied in tray packaging, which is standard for active production components. Original packaging specifications for T201KV3KE are not documented in available data. Verify packaging requirements for your assembly process before procurement.

Frequently Asked Questions (FAQ)

Q: Can T201KV3PE be used as a direct replacement for T201KV3KE in existing assemblies?

A: Yes. Both parts are electrically and mechanically identical. They share the same circuit configuration (DPDT), current rating (0.4VA), voltage ratings (20V AC/DC), panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), and actuator specifications. No circuit redesign or mechanical modification is required.

Q: What is the primary reason to switch from T201KV3KE to T201KV3PE?

A: The T201KV3KE is classified as obsolete and is no longer in active production. The T201KV3PE maintains active product status with current manufacturing support, ensuring reliable long-term supply and availability.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts have identical electrical specifications: 0.4VA current rating at 20V AC/DC, DPDT configuration, On-On switching function, and 60,000-cycle electrical life rating.

Q: Do these parts have the same mechanical footprint?

A: Yes. Both parts are panel-mount switches with identical actuator length (16.26mm), panel cutout dimensions (circular 6.35mm diameter), and bushing thread specification (1/4-40). They are mechanically interchangeable.

Q: What is the difference in RoHS compliance between these parts?

A: The T201KV3KE carries RoHS Compliant certification. The T201KV3PE carries ROHS3 Compliant certification, which represents a more current compliance standard. Both parts meet RoHS requirements; ROHS3 indicates compliance with the latest regulatory revision.

Q: Are there packaging differences I should be aware of?

A: The T201KV3PE is supplied in tray packaging. Original packaging information for T201KV3KE is not specified in available documentation. Confirm packaging requirements with your procurement or assembly department before ordering.

Q: Can I use T201KV3PE in applications with operating temperatures below -30°C or above 85°C?

A: No. Both parts are rated for -30°C to 85°C operating temperature range. Applications requiring operation outside this range require a different component selection.

Q: Is the T201KV3PE subject to any additional regulatory tracking?

A: Yes. The T201KV3PE is marked as REACH Affected, indicating it is subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. This may be relevant for applications in European markets or for customers with REACH compliance requirements.
