C&K 7101MD9CLE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7101MD9CLE is a toggle switch with SPDT (Single Pole Double Throw) configuration rated for 5A at 120V AC and 28V DC. This through-hole mounted switch features epoxy sealed terminals and a brass chrome-plated actuator with 100,000 electrical cycles. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7101MD9CLE are identified based on matching electrical and mechanical parameters that ensure functional compatibility. The critical parameters for substitution are:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Current rating (5A AC/DC)
• Voltage ratings (120V AC, 28V DC)
• Mounting type (Through Hole)
• Termination style (PC Pin)
• Actuator type (Standard Round)
• Operating temperature range (-30°C to 85°C)

Substitutes are grouped into two categories: direct manufacturer equivalents from C&K and similar cross-manufacturer alternatives that meet all electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

7101MD9CRE (Direct C&K Equivalent): This part is the primary substitute for the obsolete 7101MD9CLE. It maintains identical electrical ratings, mechanical configuration, and electrical life specifications. Both parts belong to the C&K 7000 series and share the same base product number (7101MD). The 7101MD9CRE is currently in active production status with 882 units in stock. RoHS compliance is maintained, though REACH status differs from the original part.

100SP1T2B4M2QE (E-Switch Cross-Manufacturer Alternative): This part provides functional equivalence across all critical electrical parameters and mounting specifications. It is suitable for applications where cross-manufacturer sourcing is acceptable. Notable differences include a shorter actuator length (5.08mm versus 6.86mm) and reduced electrical life rating (40,000 cycles versus 100,000 cycles). This part maintains ROHS3 compliance and REACH unaffected status. Selection of this alternative should account for the reduced cycle life in high-frequency switching applications.

Frequently Asked Questions (FAQ)

Q: Can the 7101MD9CRE directly replace the 7101MD9CLE without circuit modifications?

A: Yes. The 7101MD9CRE maintains identical electrical ratings (5A at 120V AC/28V DC), circuit configuration (SPDT On-On), and mechanical mounting specifications (Through Hole, PC Pin termination). Both parts operate across the same temperature range (-30°C to 85°C) and deliver equivalent electrical life (100,000 cycles).

Q: What is the primary difference between the 7101MD9CRE and 100SP1T2B4M2QE?

A: The 7101MD9CRE is a direct C&K equivalent with identical specifications. The 100SP1T2B4M2QE is a cross-manufacturer alternative from E-Switch with two notable differences: actuator length (5.08mm versus 6.86mm) and electrical life (40,000 cycles versus 100,000 cycles). Electrical performance and voltage ratings are equivalent.

Q: Does actuator length affect mechanical compatibility?

A: Actuator length may affect panel cutout clearance and operator feel. The 7101MD9CRE maintains the original 6.86mm length. The 100SP1T2B4M2QE has a shorter 5.08mm actuator and should be evaluated for mechanical fit in existing panel designs.

Q: Are there compliance differences between these parts?

A: All three parts are RoHS compliant. The 7101MD9CLE and 100SP1T2B4M2QE are REACH unaffected. The 7101MD9CRE is REACH affected. All parts carry EAR99 ECCN classification and the same HTSUS code (8536.50.9065).

Q: Which substitute is recommended for high-cycle applications?

A: The 7101MD9CRE is recommended for applications requiring extended electrical life. It maintains the 100,000-cycle rating of the original part. The 100SP1T2B4M2QE is rated for 40,000 cycles and should be evaluated based on specific application cycle requirements.
