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

Part Overview

The C&K 7201SDAME is a panel-mount toggle switch with DPDT (Double Pole Double Throw) configuration rated for 5A at 120V AC and 28V DC. This component features a standard round actuator with epoxy sealed terminals and is designed for on-on switching applications. The 7201SDAME is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system maintenance and new design implementations where this functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7201SDAME are identified based on strict compatibility criteria. The primary substitution parameters are:

• Circuit configuration (DPDT required)
• Switch function (On-On operation)
• Mounting type (Panel Mount, Right Angle)
• Termination style (PC Pin)
• Panel cutout dimensions (Circular - 6.35mm Dia)
• Bushing thread specification (1/4-40)
• Operating temperature range (-30°C to 85°C minimum)

Two substitute parts meet these core mechanical and electrical interface requirements:

Direct Substitute (C&K 7201SDASE): Identical electrical ratings (5A, 120V AC, 28V DC), same series, same mechanical interface. Primary difference is active product status and improved RoHS3 compliance.

Similar Substitute (TE Connectivity 2-1825138-2): Maintains DPDT configuration, on-on function, and identical mechanical interface. Operates at reduced electrical ratings (0.4VA, 20V AC/DC) and lower electrical life (6,000 cycles). Suitable only for applications within these reduced specifications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: The C&K 7201SDASE is the primary substitute for the obsolete 7201SDAME. Both parts maintain identical electrical ratings, mechanical interfaces, and actuator dimensions. The 7201SDASE is an active product with ROHS3 compliance and REACH affected status, making it suitable for new designs and ongoing production requiring full regulatory compliance.

For Reduced-Load Applications: The TE Connectivity 2-1825138-2 provides mechanical and functional compatibility but operates at significantly reduced electrical specifications (0.4VA at 20V versus 5A at 120V AC). This part is suitable only for low-power switching applications where the reduced current and voltage ratings are acceptable. The 6,000-cycle electrical life is substantially lower than the main part's 100,000 cycles, limiting its use in high-cycle applications.

Compliance Considerations: Both substitute parts are ROHS3 compliant and REACH affected, meeting current regulatory requirements. The main part (7201SDAME) is RoHS non-compliant and REACH unaffected, reflecting its obsolete status.

Frequently Asked Questions (FAQ)

Q: Can the 7201SDASE directly replace the 7201SDAME in existing applications?

A: Yes. The 7201SDASE maintains identical electrical ratings (5A, 120V AC, 28V DC), circuit configuration (DPDT), switch function (On-On), and mechanical interface specifications including panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), and actuator length (12.45mm). No circuit modifications are required.

Q: What are the limitations of using the TE Connectivity 2-1825138-2 as a substitute?

A: The 2-1825138-2 operates at reduced electrical ratings (0.4VA at 20V AC/DC versus 5A at 120V AC/28V DC) and has lower electrical life (6,000 cycles versus 100,000 cycles). It is suitable only for applications operating within these reduced specifications. Mechanical interface compatibility is maintained.

Q: Are there packaging differences between the substitute parts?

A: Yes. The 7201SDAME is supplied with dash packaging, the 7201SDASE in trays, and the 2-1825138-2 in bulk. These packaging differences do not affect component functionality or electrical performance.

Q: Do the substitute parts have different actuator dimensions?

A: The 7201SDASE maintains the same actuator length as the main part (12.45mm). The 2-1825138-2 has a shorter actuator length (10.41mm), which may affect panel aesthetics but does not impact electrical function or mechanical mounting compatibility.

Q: What is the difference in electrical life between the parts?

A: The 7201SDAME and 7201SDASE both provide 100,000 electrical cycles. The 2-1825138-2 provides 6,000 cycles. For applications requiring frequent switching, the C&K parts are more suitable.

Q: Are all substitute parts RoHS and REACH compliant?

A: The 7201SDASE and 2-1825138-2 are both ROHS3 compliant and REACH affected. The original 7201SDAME is RoHS non-compliant and REACH unaffected, reflecting its obsolete classification.
