U41MY9AV2ME Toggle Switch 4PDT Equivalent & Substitute Parts

Part Overview

The U41MY9AV2ME is a 4PDT toggle switch manufactured by C&K, rated for 5A at 120V AC and 28V DC. This component features through-hole, right-angle vertical mounting with PC pin termination and epoxy sealed terminals. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs requiring compatible switching functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Circuit configuration (4PDT required)
• Switch function (On-On operation)
• Mounting type (Through hole, right angle, vertical)
• Actuator type and length (Standard round, 5.08mm)
• Termination style (PC pin)
• Current and voltage ratings (must meet or exceed application requirements)
• Operating temperature range compatibility
• Physical form factor compatibility

Substitute parts are grouped into two categories: direct equivalents from the same manufacturer with identical electrical specifications, and cross-manufacturer alternatives with compatible electrical and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

U41MY9AV2SE (C&K) is the primary direct substitute. This part maintains identical electrical specifications, mounting configuration, and actuator dimensions as the obsolete U41MY9AV2ME. Both parts are RoHS compliant and feature epoxy sealed terminals. The U41MY9AV2SE is currently in active production status with 641 units in stock.

34A4P12B4M7GT (Grayhill Inc.) is compatible for applications requiring 5A at 125V AC. This part meets the mechanical and electrical requirements but has a reduced electrical life of 40,000 cycles compared to the original 100,000 cycles. Selection of this part requires confirmation that the lower cycle rating is acceptable for the intended application.

A423M1D9AV2B (Electroswitch) is suitable only for low-current applications rated at 0.5VA maximum. This part is not recommended as a general substitute due to significantly reduced current capacity.

A423M1D9AV2Q (Electroswitch) is compatible for applications requiring 6A at 125V AC. This part exceeds the original current rating and maintains the required mechanical form factor. Operating temperature range extends to 90°C, providing additional thermal margin. Electrical life is rated at 60,000 cycles.

All substitute parts maintain the required 4PDT circuit configuration, On-On switch function, through-hole right-angle vertical mounting, standard round 5.08mm actuator, and PC pin termination.

Frequently Asked Questions (FAQ)

Q: Can U41MY9AV2SE directly replace U41MY9AV2ME without circuit modifications?

A: Yes. U41MY9AV2SE is a direct equivalent with identical electrical ratings (5A at 120V AC, 28V DC), mechanical mounting, and actuator specifications. No circuit modifications are required.

Q: What is the primary difference between the main part and its direct substitute?

A: The U41MY9AV2ME is obsolete, while U41MY9AV2SE is in active production. Both parts share identical electrical and mechanical specifications, including 100,000 cycle electrical life and epoxy sealed terminals.

Q: Can 34A4P12B4M7GT be used in all applications where U41MY9AV2ME was used?

A: 34A4P12B4M7GT is mechanically and electrically compatible for most applications. However, the electrical life is reduced to 40,000 cycles compared to the original 100,000 cycles. Applications requiring extended cycle life should use U41MY9AV2SE instead.

Q: What is the significance of the current rating difference in A423M1D9AV2B?

A: A423M1D9AV2B is rated at 0.5VA, which is substantially lower than the original 5A rating. This part is suitable only for low-current signal switching applications and is not recommended as a general substitute for the U41MY9AV2ME.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts meet RoHS compliance requirements. U41MY9AV2SE and 34A4P12B4M7GT are RoHS3 compliant. A423M1D9AV2B and A423M1D9AV2Q are RoHS compliant.

Q: What mounting compatibility should be verified when selecting a substitute?

A: All substitute parts maintain through-hole, right-angle, vertical mounting with standard round 5.08mm actuators and PC pin termination. Physical form factor and PCB cutout dimensions are compatible across all listed parts.

Q: How do operating temperature ranges compare across substitute options?

A: The original U41MY9AV2ME operates from -30°C to 85°C. U41MY9AV2SE maintains this range. Electroswitch parts (A423M1D9AV2B and A423M1D9AV2Q) extend to -30°C to 90°C, providing additional thermal margin. Grayhill 34A4P12B4M7GT operates within -30°C to 85°C.
