C&K 7101MY9AME Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7101MY9AME is a toggle switch with SPDT (Single Pole Double Throw) configuration rated for 5A at 120V AC and 28V DC. This through-hole, right-angle mounted switch features epoxy sealed terminals and a brass chrome-plated actuator. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7101MY9AME is determined by the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Mounting type (Through Hole, Right Angle)
• Actuator type and length (Standard Round, 5.08mm)
• Termination style (PC Pin)
• Current and voltage ratings (minimum 5A AC/DC, minimum 120V AC, minimum 28V DC)
• Operating temperature range (-30°C to 85°C minimum)

Parts meeting these criteria are classified as direct equivalents or similar substitutes based on their electrical ratings and product status.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent: C&K 7101MY9ASE

The 7101MY9ASE is the direct equivalent to the 7101MY9AME. Both parts share identical electrical ratings, mechanical configuration, and operating parameters. The 7101MY9ASE is currently in active production status, making it the primary replacement for the obsolete 7101MY9AME. Both parts maintain RoHS compliance and are suitable for direct substitution in existing designs.

Similar Substitutes: Electroswitch A123M1D9AG and A123M1D9AQ

The Electroswitch A123M1D9AG and A123M1D9AQ are similar substitutes that exceed the electrical requirements of the 7101MY9AME. Both parts provide higher current ratings (6A versus 5A) and higher AC voltage ratings (125V versus 120V), with identical DC voltage ratings and mechanical mounting configurations. Both are in active production and RoHS compliant. The extended operating temperature range (-30°C to 90°C) provides additional thermal margin. However, the electrical life rating is lower (60,000 cycles versus 100,000 cycles), which should be evaluated against application duty cycle requirements.

Frequently Asked Questions (FAQ)

Q: Can the C&K 7101MY9ASE be used as a direct replacement for the 7101MY9AME?

A: Yes. The 7101MY9ASE is a direct equivalent with identical electrical ratings, mechanical configuration, and operating parameters. No circuit modifications are required.

Q: What are the key differences between the C&K 7101MY9AME and the Electroswitch A123M1D9AG/A123M1D9AQ?

A: The Electroswitch parts provide higher current (6A versus 5A) and AC voltage ratings (125V versus 120V). The Electroswitch parts have a lower electrical life rating (60,000 cycles versus 100,000 cycles) and an extended operating temperature range (-30°C to 90°C versus -30°C to 85°C).

Q: Are all substitute parts RoHS compliant?

A: Yes. The C&K 7101MY9ASE is RoHS compliant, and both Electroswitch parts (A123M1D9AG and A123M1D9AQ) are RoHS compliant.

Q: Do the Electroswitch substitutes require any design modifications?

A: No design modifications are required. The Electroswitch parts maintain the same SPDT circuit configuration, On-On switch function, through-hole right-angle mounting, and PC pin termination as the original part. The higher electrical ratings provide additional design margin.

Q: Which substitute should be selected for new designs?

A: For new designs, the C&K 7101MY9ASE is recommended as the primary choice due to identical specifications and active production status. The Electroswitch A123M1D9AG and A123M1D9AQ are suitable alternatives when higher current or voltage ratings are beneficial to the application.

Q: What is the impact of the lower electrical life rating on the Electroswitch substitutes?

A: The Electroswitch parts are rated for 60,000 cycles versus 100,000 cycles for the C&K parts. Application duty cycle requirements should be evaluated to determine if this difference is significant for the intended use.
