C&K 7201SD9AME Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7201SD9AME is a through-hole, right-angle toggle switch with DPDT (Double Pole Double Throw) configuration rated for 5A at 120V AC and 28V DC. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The switch features epoxy sealed terminals, brass chrome-plated actuator, and operates across -30°C to 85°C with 100,000 electrical cycles rated life.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7201SD9AME are qualified based on the following critical parameters that determine functional compatibility:

Electrical Parameters (Non-Negotiable):

• Circuit configuration: DPDT
• Switch function: On-On
• Current rating: 5A (AC/DC)
• Voltage rating: 120V AC / 28V DC minimum

Mechanical Parameters (Non-Negotiable):

• Mounting type: Through Hole, Right Angle
• Termination style: PC Pin
• Actuator type: Standard Round
• Bushing thread: Unthreaded

Environmental Parameters:

• Operating temperature range: -30°C to 85°C
• Moisture sensitivity level: 1 (Unlimited)

All substitute parts listed meet these core requirements. Variations in actuator length (12.19mm to 12.70mm), electrical life cycles, and compliance certifications do not affect functional substitution within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

Direct Manufacturer Equivalent: The C&K 7201SD9ASE is the primary substitute for the obsolete 7201SD9AME. Both parts share identical electrical ratings, mechanical configuration, and operating parameters. The 7201SD9ASE is currently in active production status with RoHS compliance, making it the preferred choice for new designs and ongoing procurement.

Cross-Manufacturer Alternatives: The TE Connectivity 1-1825138-7 (Gemini A series) and E-Switch 100AWDP1T1B4M6QE (100A series) meet all core electrical and mechanical substitution criteria. Both are active products with ROHS3 compliance. The E-Switch variant provides enhanced ingress protection (IP67), suitable for applications requiring dust and moisture resistance. The TE Connectivity option offers lower electrical life (6,000 cycles) compared to the original specification (100,000 cycles), requiring evaluation against application duty cycle requirements.

Compliance Considerations: The original 7201SD9AME is RoHS non-compliant. All substitute parts listed are RoHS compliant or ROHS3 compliant, supporting regulatory requirements for new designs and markets with RoHS mandates.

Frequently Asked Questions (FAQ)

Q: Can the C&K 7201SD9ASE directly replace the 7201SD9AME without circuit modification? A: Yes. The 7201SD9ASE is electrically and mechanically identical to the 7201SD9AME. Both parts feature DPDT configuration, 5A/120V AC rating, through-hole right-angle mounting, and PC pin termination. No circuit redesign is required.

Q: What is the significance of the actuator length variation (12.19mm to 12.70mm) among substitute parts? A: Actuator length affects panel cutout clearance and operator feel. The 7201SD9AME and 7201SD9ASE both specify 12.45mm. The TE Connectivity part (12.19mm) and E-Switch part (12.70mm) may require mechanical verification for panel fit. Consult mechanical drawings and panel specifications before selection.

Q: Why does the TE Connectivity 1-1825138-7 have lower electrical life (6,000 cycles) than the original? A: Electrical life rating reflects design and testing specifications for each manufacturer's product line. The 6,000-cycle rating is still suitable for many applications. Evaluate against your application's expected switching frequency and duty cycle to determine adequacy.

Q: Is the E-Switch 100AWDP1T1B4M6QE suitable for sealed or outdoor applications? A: The E-Switch part includes IP67 ingress protection (dust tight, waterproof), making it suitable for sealed and outdoor environments. The original 7201SD9AME does not specify ingress protection. Select the E-Switch variant if environmental sealing is a design requirement.

Q: Are all substitute parts available in the same packaging as the original? A: The 7201SD9AME and 7201SD9ASE packaging is not specified in available data. The TE Connectivity and E-Switch parts are supplied in bulk packaging. Confirm packaging requirements and minimum order quantities with your supplier.

Q: Which substitute part is recommended for new designs? A: The C&K 7201SD9ASE is the recommended primary choice for new designs, as it is the direct manufacturer equivalent with active production status and RoHS compliance. Cross-manufacturer alternatives are suitable if supply constraints or specific performance requirements (such as IP67 sealing) necessitate their use.
