U11MD9CME Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The U11MD9CME is a toggle switch with SPDT (Single Pole Double Throw) circuit configuration manufactured by C&K in the 7000 series. This through-hole mounted switch is rated for 5A at 120V AC and 28V DC, featuring a standard round actuator with brass chrome-plated construction and epoxy sealed terminals. The product is currently obsolete, making identification of equivalent and substitute parts essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the U11MD9CME is determined by strict equivalence in the following electrical and mechanical parameters:

• Circuit configuration: SPDT
• Switch function: On-On
• Current rating: 5A (AC/DC)
• Voltage rating: 120V AC / 28V DC
• Mounting type: Through Hole
• Termination style: PC Pin
• Operating temperature range: -30°C to 85°C
• Actuator type: Standard Round
• Material and sealing: Brass chrome-plated with epoxy sealed terminals

Two substitute parts meet these criteria: U11MD9CSE (C&K, same series, active status) and 100SP1T2B4M2QE (E-Switch, different series, active status). Both maintain electrical equivalence while differing in specific mechanical dimensions and electrical life ratings.

Parameter Comparison

Engineering Selection Recommendations

U11MD9CSE is the primary substitute for U11MD9CME. Both parts share identical electrical ratings, mechanical dimensions, and operating characteristics within the C&K 7000 series. U11MD9CSE holds active product status and maintains equivalent RoHS3 compliance. The primary distinction is REACH status: U11MD9CSE is REACH Affected while U11MD9CME is REACH Unaffected. This difference requires evaluation based on end-use application and regulatory jurisdiction.

100SP1T2B4M2QE from E-Switch provides electrical equivalence with identical voltage and current ratings. This part maintains ROHS3 compliance and REACH Unaffected status. However, two mechanical differences exist: actuator length is reduced to 5.08mm (versus 6.86mm), and electrical life is rated at 40,000 cycles (versus 100,000 cycles). Selection of this substitute requires confirmation that panel cutout geometry accommodates the shorter actuator and that the reduced electrical life cycle rating aligns with application duty cycle requirements.

Frequently Asked Questions (FAQ)

Q: Can U11MD9CSE directly replace U11MD9CME without PCB modification?

A: Yes. U11MD9CSE maintains identical electrical ratings (5A at 120V AC / 28V DC), circuit configuration (SPDT On-On), mounting type (Through Hole), termination style (PC Pin), and actuator dimensions (6.86mm standard round). No PCB layout changes are required.

Q: What is the impact of the REACH status difference between U11MD9CME and U11MD9CSE?

A: U11MD9CME is REACH Unaffected while U11MD9CSE is REACH Affected. This distinction applies to products manufactured or imported into the European Union. Applications subject to REACH regulations must evaluate compliance requirements for the specific end-use and geographic market.

Q: Is 100SP1T2B4M2QE suitable for high-cycle applications?

A: 100SP1T2B4M2QE is rated for 40,000 electrical cycles compared to 100,000 cycles for U11MD9CME and U11MD9CSE. Applications requiring extended operational life or frequent switching should prioritize U11MD9CSE. The E-Switch part is suitable for applications within its 40,000-cycle specification.

Q: Does the 5.08mm actuator length of 100SP1T2B4M2QE affect panel mounting?

A: The actuator length reduction from 6.86mm to 5.08mm may affect panel cutout geometry and user interface ergonomics. Panel design must accommodate the shorter actuator protrusion. Mechanical fit verification is required before implementation.

Q: Are all three parts RoHS compliant?

A: Yes. U11MD9CME and 100SP1T2B4M2QE are ROHS3 Compliant. U11MD9CSE is RoHS Compliant. All three parts meet RoHS requirements for their respective compliance designations.
