C&K 7201SD9AV2ME Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7201SD9AV2ME is a DPDT toggle switch rated for 5A at 120V AC with through-hole, right-angle vertical mounting. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The switch features epoxy sealed terminals, brass chrome-plated actuator, and 100,000 electrical life cycles.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7201SD9AV2ME are classified based on electrical and mechanical parameter compatibility:

Direct Equivalent (Same Manufacturer): The C&K 7201SD9AV2SE maintains identical electrical specifications (DPDT, 5A, 120V AC, 28V DC), mounting configuration (through-hole right-angle vertical), and mechanical design (12.45mm actuator, PC pin termination). The primary difference is product status (active vs. obsolete) and RoHS compliance (compliant vs. non-compliant).

Cross-Manufacturer Substitute: The E-Switch 100AWDP1T1B4M7QE provides equivalent electrical performance (DPDT, 5A, 120V AC, 28V DC) and identical mounting type. Substitution is valid based on matching circuit configuration, current/voltage ratings, and physical mounting interface. Notable differences include actuator length (12.70mm vs. 12.45mm), electrical life rating (30,000 vs. 100,000 cycles), and ingress protection (IP67 vs. unspecified).

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: The C&K 7201SD9AV2SE is the primary substitute for the obsolete 7201SD9AV2ME. Both components share identical electrical ratings, mechanical configuration, and actuator dimensions. Selection of 7201SD9AV2SE is appropriate for applications requiring RoHS compliance and active product support.

For Cross-Manufacturer Substitution: The E-Switch 100AWDP1T1B4M7QE is suitable where electrical and mounting compatibility are the primary requirements. This part is appropriate for applications requiring enhanced ingress protection (IP67 rating). The 0.25mm actuator length difference and reduced electrical life rating (30,000 vs. 100,000 cycles) must be evaluated against specific application demands.

Compliance Considerations: Applications subject to RoHS regulations should utilize either 7201SD9AV2SE or 100AWDP1T1B4M7QE. The original 7201SD9AV2ME is RoHS non-compliant and unsuitable for new designs in regulated markets.

Frequently Asked Questions (FAQ)

Q: Can the 7201SD9AV2SE directly replace the 7201SD9AV2ME? A: Yes. Both parts share identical DPDT circuit configuration, 5A current rating, 120V AC and 28V DC voltage ratings, through-hole right-angle vertical mounting, and 12.45mm actuator length. Electrical life and cycle rating are identical at 100,000 cycles.

Q: What is the primary difference between 7201SD9AV2ME and 7201SD9AV2SE? A: Product status and regulatory compliance. The 7201SD9AV2ME is obsolete and RoHS non-compliant, while 7201SD9AV2SE is active and RoHS compliant. Electrical and mechanical specifications are identical.

Q: Is the E-Switch 100AWDP1T1B4M7QE a suitable substitute? A: Yes, for applications where electrical ratings and mounting type are the primary compatibility criteria. The part maintains DPDT configuration, 5A current, 120V AC/28V DC voltage ratings, and through-hole right-angle vertical mounting. The 0.25mm longer actuator (12.70mm vs. 12.45mm) and lower electrical life rating (30,000 cycles) must be verified against application requirements.

Q: What is the impact of the 0.25mm actuator length difference? A: Panel cutout and mechanical clearance must be verified. The E-Switch 100AWDP1T1B4M7QE actuator extends 0.25mm further than the original part. This difference may affect panel mounting fit and should be confirmed before substitution.

Q: Does the E-Switch part offer any advantages? A: The 100AWDP1T1B4M7QE provides IP67 ingress protection (dust tight, waterproof), which the original part does not specify. This is beneficial for applications requiring enhanced environmental sealing.

Q: What is the electrical life difference between parts? A: The C&K parts (7201SD9AV2ME and 7201SD9AV2SE) are rated for 100,000 cycles, while the E-Switch 100AWDP1T1B4M7QE is rated for 30,000 cycles. Applications with high switching frequency should prioritize the C&K parts.
