C&K 7211MD9ALE Toggle Switch SP3T Equivalent & Substitute Parts

Part Overview

The C&K 7211MD9ALE is a single-pole triple-throw (SP3T) toggle switch rated for 5A at 120V AC and 28V DC. This through-hole, right-angle mounted component features a standard round actuator with brass chrome-plated construction and is designed for On-On-On switching applications. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7211MD9ALE is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SP3T (single-pole triple-throw)
• Switch function: On-On-On
• Current rating: 5A (AC/DC)
• Voltage ratings: 120V AC and 28V DC minimum
• Mounting type: Through hole, right angle
• Termination style: PC pin
• Actuator type: Standard round
• Operating temperature range: -30°C to 85°C
• Electrical life: 40,000 cycles

Two substitute parts meet these criteria: the C&K 7211MD9ARE (direct manufacturer alternative within the same series) and the E-Switch 100DP6T2B4M6QE (cross-manufacturer equivalent). Both maintain identical electrical specifications and mechanical mounting characteristics.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7211MD9ARE is the primary substitute for the obsolete 7211MD9ALE. Both components are from the same manufacturer and series, ensuring design continuity. The 7211MD9ARE is currently in active production status with improved compliance: it is RoHS Compliant and REACH Affected, compared to the non-compliant status of the original part. This makes it the preferred choice for new designs and ongoing production requiring regulatory compliance.

The E-Switch 100DP6T2B4M6QE provides a cross-manufacturer alternative with identical electrical and mechanical specifications. It is ROHS3 Compliant and REACH Unaffected. This option is suitable for applications where multi-source qualification is required or where E-Switch components are already established in the supply chain.

Both substitutes differ from the original part in actuator length: the 7211MD9ARE has a 6.86mm actuator, and the 100DP6T2B4M6QE has a 5.08mm actuator, compared to the original 21.34mm. Panel cutout and mechanical fit must be evaluated based on specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the 7211MD9ARE directly replace the 7211MD9ALE in existing designs?

A: The 7211MD9ARE maintains identical electrical ratings, circuit configuration, and mounting type. However, the actuator length differs significantly (6.86mm versus 21.34mm), requiring mechanical fit verification in the specific application enclosure.

Q: What is the difference between the C&K and E-Switch alternatives?

A: Both provide equivalent electrical performance and mechanical mounting. The primary differences are manufacturer, series designation, and regulatory compliance status. The C&K 7211MD9ARE is REACH Affected, while the E-Switch 100DP6T2B4M6QE is REACH Unaffected. Selection depends on supply chain qualification and regulatory requirements.

Q: Are there packaging differences between these parts?

A: The 7211MD9ALE and 7211MD9ARE are packaged as individual units. The E-Switch 100DP6T2B4M6QE is supplied in bulk packaging. Procurement quantities and handling procedures may differ accordingly.

Q: Does the shorter actuator length affect electrical performance?

A: No. Actuator length is a mechanical design parameter that affects panel mounting and user interface ergonomics, not electrical switching characteristics. All three parts maintain identical current ratings, voltage ratings, and electrical life specifications.

Q: Which substitute is recommended for new product designs?

A: The C&K 7211MD9ARE is recommended for new designs requiring C&K component continuity. For applications with established E-Switch qualification, the 100DP6T2B4M6QE is equally suitable. Both are in active production status with current regulatory compliance.
