SWW246A7 Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The SWW246A7 is an APEM Inc. toggle switch featuring DPDT (Double Pole Double Throw) configuration with On-On switching function. This through-hole, right-angle mounted component is rated for 5A AC at 125V and 4A DC at 30V, with a sealed design and 40,000 electrical cycle life. The part is Active status and ROHS3 compliant, making it suitable for industrial and commercial applications requiring reliable switching control.

Equivalent and substitute parts are identified based on matching electrical ratings, mechanical mounting characteristics, and functional circuit configuration. Alternative components listed below maintain compatibility with the same PC pin termination style and through-hole vertical mounting orientation.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SWW246A7 are grouped based on the following critical parameters that determine functional compatibility:

Primary Matching Criteria:

• Circuit configuration: DPDT
• Switch function: On-On
• Mounting type: Through hole, right angle, vertical orientation
• Termination style: PC pin
• Actuator type: Standard round

Electrical Rating Categories:

Full-Rating Substitutes (5A AC/DC, 120-125V AC): Parts maintaining equivalent current and voltage specifications to the SWW246A7, suitable for direct replacement in applications requiring 5A switching capacity at 120-125V AC.

Reduced-Rating Substitutes (0.4VA, 20V AC/DC): Parts with lower electrical ratings, applicable only in applications with reduced power requirements. These components are not suitable for circuits designed for the full 5A/125V specification of the SWW246A7.

Substitution decisions must account for the specific electrical demands of the target application. Parts with lower current or voltage ratings cannot be used in circuits requiring the full performance envelope of the SWW246A7.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement Candidates (Equivalent Electrical Performance):

The 100DP1T2B4M7QE (E-Switch) and 7201MD9AV2QE (C&K) maintain electrical specifications compatible with the SWW246A7 design envelope. Both parts are rated for 5A AC/DC operation at 120-128V AC and 28-30V DC, with ROHS3 compliance and Active product status. These components are suitable for applications where the full 5A/125V performance of the SWW246A7 is required. The 7201MD9AV2QE offers extended electrical life (100,000 cycles versus 40,000), providing enhanced durability in high-cycle applications.

Limited-Application Substitutes (Reduced Electrical Ratings):

The 7201MD9AV2BE and E201MD1AV2BE (both C&K) are rated for 0.4VA at 20V AC/DC only. These parts are not suitable for direct replacement in circuits designed for the SWW246A7's 5A/125V specification. Use these components only in applications with reduced power requirements that do not exceed 0.4VA at 20V. The E201MD1AV2BE includes IP57 ingress protection, applicable to sealed or moisture-exposed environments.

Compliance and Availability:

All substitute parts maintain ROHS3 compliance and Active product status. The C&K parts (7201MD9AV2QE, 7201MD9AV2BE, E201MD1AV2BE) carry REACH Affected designation, while the E-Switch 100DP1T2B4M7QE is REACH Unaffected. Inventory availability varies: E-Switch 100DP1T2B4M7QE (2078 units), C&K 7201MD9AV2QE (790 units), C&K 7201MD9AV2BE (912 units), and C&K E201MD1AV2BE (3899 units).

Frequently Asked Questions (FAQ)

Q: Can the 7201MD9AV2BE or E201MD1AV2BE replace the SWW246A7 in my application?

A: Only if your circuit operates at 0.4VA or less at 20V or below. These parts are rated for significantly lower electrical performance and cannot handle the 5A/125V specification of the SWW246A7. Verify your actual circuit requirements before substitution.

Q: What is the difference between the 100DP1T2B4M7QE and 7201MD9AV2QE?

A: Both are rated for 5A AC/DC at 120-128V and are electrically equivalent to the SWW246A7. The 7201MD9AV2QE offers 100,000 electrical cycles versus 40,000 for the 100DP1T2B4M7QE, providing longer operational life. The 100DP1T2B4M7QE has a shorter actuator length (5.08mm versus 6.86mm). Select based on cycle life requirements and panel cutout dimensions.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 compliant. However, the C&K parts (7201MD9AV2QE, 7201MD9AV2BE, E201MD1AV2BE) are REACH Affected, while the E-Switch 100DP1T2B4M7QE is REACH Unaffected. Verify REACH compliance requirements for your specific application and region.

Q: What is the significance of actuator length differences?

A: Actuator length affects panel engagement and tactile feedback. The SWW246A7 has a 7.50mm actuator. Substitutes range from 5.08mm to 7.62mm. Verify that the substitute actuator length is compatible with your panel cutout and mechanical design before installation.

Q: Does packaging format affect compatibility?

A: Packaging (Bulk versus Tray) does not affect electrical or mechanical compatibility. It impacts handling, storage, and ordering logistics. The SWW246A7 is supplied in Bulk; substitute parts from C&K are supplied in Tray format. Confirm packaging requirements with your procurement process.

Q: Can I use the E201MD1AV2BE in a wet environment?

A: The E201MD1AV2BE includes IP57 ingress protection (dust protected, waterproof), making it suitable for sealed or moisture-exposed environments. However, it is rated for only 0.4VA at 20V, so it cannot replace the SWW246A7 in high-power applications regardless of environmental protection.
