C&K 7103K2CME Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7103K2CME is a toggle switch with SPDT (Single Pole Double Throw) configuration, rated for 5A at 120V AC and 28V DC. This panel-mount switch features a locking lever actuator and is designed for On-Off-On switching applications. The 7103K2CME 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 7103K2CME is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-Off-On)
• Current rating (5A AC/DC)
• Voltage ratings (120V AC, 28V DC)
• Mounting type (Panel Mount)
• Actuator type and length (Locking Lever, 17.88mm)
• Termination style (PC Pin)
• Panel cutout dimensions (Circular - 6.35mm Dia)
• Bushing thread specification (1/4-40)
• Operating temperature range (-30°C ~ 85°C)
• Electrical life (40,000 Cycles)

The C&K 7103K2CSE meets all these criteria and serves as a direct substitute. The primary distinction is product status: the 7103K2CME is obsolete, while the 7103K2CSE is active and available for procurement.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7103K2CSE is the direct substitute for the obsolete 7103K2CME. Both parts share identical electrical and mechanical specifications, ensuring functional compatibility in existing designs.

The 7103K2CSE offers improved regulatory compliance: it is RoHS Compliant and REACH Affected, compared to the 7103K2CME which is RoHS non-compliant and REACH Unaffected. For new designs or systems requiring compliance with current environmental regulations, the 7103K2CSE is the appropriate selection.

Both parts carry the same ECCN (EAR99) and HTSUS (8536.50.9065) classifications, indicating equivalent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the 7103K2CSE directly replace the 7103K2CME in existing applications?

A: Yes. The 7103K2CSE is electrically and mechanically identical to the 7103K2CME. All electrical ratings, switching characteristics, mounting dimensions, and actuator specifications are equivalent. Direct substitution is possible without circuit or mechanical redesign.

Q: What is the primary reason to switch from 7103K2CME to 7103K2CSE?

A: The 7103K2CME is obsolete and no longer manufactured. The 7103K2CSE is the active equivalent part from C&K and is available for procurement. Additionally, the 7103K2CSE meets current RoHS compliance requirements.

Q: Are there any differences in panel mounting between these parts?

A: No. Both parts use identical panel cutout dimensions (Circular - 6.35mm Dia) and bushing thread specification (1/4-40). Physical installation is identical.

Q: Do the RoHS and REACH compliance differences affect electrical performance?

A: No. Compliance status reflects manufacturing process and material sourcing standards, not electrical or mechanical performance. Both parts deliver identical switching performance and reliability.

Q: What is the inventory status for the 7103K2CSE?

A: The 7103K2CSE has 1085 pieces in stock as new original inventory, ensuring availability for immediate procurement.
