C&K 7101MD9AGE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7101MD9AGE is a through-hole, right-angle toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This component is currently active in production. Substitute parts may be required due to inventory constraints, supply chain considerations, or application-specific parameter requirements within the allowed electrical and mechanical specifications for SPDT toggle switches.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7101MD9AGE is determined by the following critical parameters:

• Circuit Configuration: Must be SPDT (Single Pole Double Throw)
• Switch Function: Must be On-On
• Mounting Type: Must be Through Hole, Right Angle
• Termination Style: Must be PC Pin
• Electrical Ratings: Current and voltage ratings must meet or exceed the application requirements
• Operating Temperature: Must support -30°C to 85°C range
• Compliance: RoHS3 compliance required

The identified substitute parts meet these core criteria while operating within acceptable parameter tolerances for SPDT toggle switch applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute - E-Switch 100SP1T2B4M6RE: This part maintains SPDT configuration, On-On function, and through-hole right-angle mounting with PC pin termination. However, the current rating of 0.4VA and voltage ratings of 20V AC/DC are significantly lower than the main part. This substitute is suitable only for low-power applications operating below 20V.

Secondary Substitutes - NKK M2012S2A2A30 and M2012S3S2W30: Both NKK parts provide higher current ratings (6A AC, 4A DC) and voltage ratings (125V AC, 30V DC) that exceed the 7101MD9AGE specifications. Both maintain SPDT configuration, On-On function, and compatible mounting and termination. However, both parts are marked as Obsolete, limiting long-term availability. The M2012S2A2A30 features the same 6.86mm actuator length as the main part, while the M2012S3S2W30 has a 6.50mm actuator length.

Compliance Status: All substitute parts are ROHS3 compliant and operate within the -30°C to 85°C temperature range, meeting regulatory requirements equivalent to the main part.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100SP1T2B4M6RE replace the C&K 7101MD9AGE in all applications?

A: No. The E-Switch part has significantly reduced electrical ratings (0.4VA at 20V maximum). It is suitable only for applications requiring less than 0.4A at voltages not exceeding 20V. Applications requiring the full 5A at 120V AC cannot use this substitute.

Q: Why are the NKK parts listed as Obsolete?

A: Product status is provided as supplied in the component database. Obsolete designation indicates these parts are no longer in active production. Availability may be limited to existing inventory. Current inventory levels are 1001 and 1013 units respectively.

Q: Are the NKK M2012S2A2A30 and M2012S3S2W30 electrically interchangeable with the 7101MD9AGE?

A: Both NKK parts meet or exceed the electrical specifications of the 7101MD9AGE. The M2012S2A2A30 matches the 6.86mm actuator length exactly. The M2012S3S2W30 has a slightly shorter 6.50mm actuator. Both maintain SPDT configuration, On-On function, through-hole right-angle mounting, and PC pin termination. Physical space constraints must be evaluated for the actuator length difference.

Q: What is the significance of Electrical Life ratings?

A: Electrical Life indicates the number of switching cycles the component is rated to perform. The 7101MD9AGE is rated for 100,000 cycles. The E-Switch substitute is rated for 40,000 cycles, and both NKK substitutes are rated for 25,000 cycles. Applications requiring high cycle counts should prioritize the main part or the E-Switch substitute.

Q: Are all parts RoHS3 compliant?

A: Yes. The main part and all three substitute parts are ROHS3 compliant, meeting environmental and regulatory requirements for restricted substances.
