U11MD9AME Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The U11MD9AME is a toggle switch with SPDT (Single Pole Double Throw) configuration manufactured by C&K in the 7000 series. This through-hole, right-angle mounted switch is rated for 5A at 120V AC and 28V DC, with a standard round actuator and epoxy sealed terminals. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the U11MD9AME are identified based on strict electrical and mechanical parameter matching within the C&K 7000 series. The substitution criteria are:

• Circuit configuration: SPDT
• Switch function: On-On
• Current rating: 5A (AC/DC)
• Voltage ratings: 120V AC and 28V DC
• Mounting type: Through Hole, Right Angle
• Actuator type and length: Standard Round, 6.86mm
• Termination style: PC Pin
• Operating temperature range: -30°C to 85°C
• Electrical life: 100,000 Cycles
• Base product number: U11MD9

The U11MD9ASE meets all these parameters and is classified as a direct manufacturer substitute.

Parameter Comparison

Engineering Selection Recommendations

The U11MD9ASE is the direct substitute for the obsolete U11MD9AME. Both parts share identical electrical ratings, mechanical dimensions, and functional specifications. The primary distinction is product status: the U11MD9ASE is currently active and available in production quantities (923 pcs in stock versus 749 pcs for the obsolete variant).

For new designs and ongoing system support, the U11MD9ASE is the appropriate selection. The substitute maintains full compatibility with existing circuit designs and PCB layouts due to identical mounting type, actuator dimensions, and termination style.

Compliance considerations: The U11MD9ASE carries RoHS compliance certification and is REACH Affected, reflecting current regulatory requirements. The obsolete U11MD9AME was ROHS3 Compliant and REACH Unaffected, indicating it predates current environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can the U11MD9ASE directly replace the U11MD9AME in existing designs?

A: Yes. The U11MD9ASE is electrically and mechanically identical to the U11MD9AME. All electrical parameters (5A at 120V AC/28V DC), circuit configuration (SPDT On-On), mounting type (Through Hole, Right Angle), and actuator specifications (Standard Round, 6.86mm) are identical. PCB layouts and circuit designs require no modification.

Q: What is the difference between ROHS3 Compliant and RoHS Compliant?

A: ROHS3 refers to the third iteration of the Restriction of Hazardous Substances directive. The U11MD9ASE carries current RoHS compliance certification, reflecting updated regulatory standards. Both variants meet hazardous substance restrictions applicable to their respective manufacturing periods.

Q: Why is the U11MD9AME listed as obsolete?

A: The U11MD9AME has been discontinued by C&K. The U11MD9ASE represents the current production equivalent within the 7000 series, maintaining all functional and electrical specifications while meeting active manufacturing and compliance requirements.

Q: Are there any packaging or inventory considerations?

A: The U11MD9ASE has higher current inventory availability (923 pcs) compared to remaining stock of the obsolete U11MD9AME (749 pcs). For new procurement, the U11MD9ASE is the recommended selection due to active production status and supply continuity.

Q: What does REACH Affected mean for the U11MD9ASE?

A: REACH Affected indicates the part is subject to the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulation. This reflects current European chemical safety requirements and does not impact electrical or mechanical performance.
