U11MD9AGE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The U11MD9AGE is a toggle switch with Single Pole Double Throw (SPDT) configuration manufactured by C&K. This through-hole, right-angle mounted switch is rated for 5A at 120V AC and 28V DC, featuring epoxy sealed terminals and a standard round brass chrome-plated actuator. The part is currently active in production with 881 units in stock.

Equivalent and substitute parts are identified when applications require alternative sourcing due to inventory constraints, supply chain considerations, or when design specifications allow for compatible alternatives meeting the same functional requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the U11MD9AGE are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Circuit configuration: SPDT
• Switch function: On-On
• Mounting type: Through Hole, Right Angle
• Termination style: PC Pin
• Actuator type: Standard Round
• Operating temperature range: -30°C to 85°C
• RoHS compliance: ROHS3 Compliant

Electrical Rating Compatibility: Substitutes must meet or exceed the voltage and current requirements of the application. The U11MD9AGE operates at 5A (AC/DC), 120V AC, and 28V DC. Substitute parts may have different electrical ratings provided they satisfy the specific application requirements.

Mechanical Compatibility: All substitute parts maintain identical mounting configuration (through-hole, right-angle) and termination style (PC pin), ensuring direct mechanical interchangeability in the PCB layout.

Engineering Selection Recommendations

U11MD9AGE (C&K) - Primary Selection

The U11MD9AGE remains the recommended primary choice. It is currently active in production with 881 units in stock, ROHS3 compliant, and rated for 5A at 120V AC with 100,000 electrical life cycles. This part meets full compliance requirements and offers the highest cycle life rating among available options.

100SP1T2B4M6RE (E-Switch) - Limited Substitution

The 100SP1T2B4M6RE shares identical mechanical compatibility and operating temperature range. However, it is rated for only 0.4VA at 20V AC/DC, which is significantly lower than the U11MD9AGE specifications. This substitute is suitable only for applications with reduced electrical requirements. It offers 40,000 electrical life cycles. ROHS3 compliant and currently active.

M2012S2A2A30/U (NKK Switches) - Not Recommended

The M2012S2A2A30/U is marked as obsolete and should not be selected for new designs. While it provides comparable voltage ratings (125V AC, 30V DC) and actuator length, the product status is discontinued. Electrical life is limited to 25,000 cycles. REACH status differs from the primary part.

Frequently Asked Questions (FAQ)

Q: Can the 100SP1T2B4M6RE replace the U11MD9AGE in all applications?

A: No. The 100SP1T2B4M6RE is rated for 0.4VA at 20V, while the U11MD9AGE is rated for 5A at 120V AC. Substitution is only valid for applications with significantly lower electrical requirements. Verify your circuit voltage and current demands before selection.

Q: What is the key difference in mechanical compatibility between these parts?

A: All three parts share identical mounting configuration (through-hole, right-angle) and termination style (PC pin). The primary mechanical difference is actuator length: U11MD9AGE and M2012S2A2A30/U both measure 6.86mm, while the 100SP1T2B4M6RE measures 5.08mm. This may affect panel cutout alignment and actuator accessibility.

Q: Why is the M2012S2A2A30/U listed if it is obsolete?

A: The M2012S2A2A30/U is provided for reference in legacy system documentation and reverse engineering applications. For new designs and production, the active U11MD9AGE or 100SP1T2B4M6RE should be selected based on electrical requirements.

Q: How do electrical life cycles affect part selection?

A: Electrical life indicates the number of switching operations before performance degradation. The U11MD9AGE supports 100,000 cycles, the 100SP1T2B4M6RE supports 40,000 cycles, and the M2012S2A2A30/U supports 25,000 cycles. Applications with frequent switching should prioritize higher cycle ratings.

Q: Are all parts RoHS3 compliant?

A: Yes. The U11MD9AGE, 100SP1T2B4M6RE, and M2012S2A2A30/U are all ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing.

Q: What packaging options are available?

A: The U11MD9AGE is supplied in trays. The 100SP1T2B4M6RE is supplied in bulk packaging. The M2012S2A2A30/U packaging information is not specified in available documentation.
