SWW249A7 Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The SWW249A7 is an active DPDT toggle switch manufactured by APEM Inc., designed for through-hole mounting with right-angle vertical orientation. This switch is rated for 5A AC at 125V and 4A DC at 30V, featuring a sealed design with 40,000 electrical life cycles. The part is ROHS3 compliant and currently in active production status with 972 units in stock.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the allowed parameter ranges for DPDT toggle switches with through-hole PC pin termination.

Key Parameters

Substitute Part Grouping Explanation

The E203MD1AV2BE from C&K is identified as a substitute based on the following matching parameters:

Circuit configuration: Both parts are DPDT with On-Off-On switching function and through-hole PC pin termination. Mounting orientation is identical (right angle, vertical). Actuator type and length are equivalent (standard round, 7.62mm vs 7.50mm). Electrical life rating matches at 40,000 cycles. Both parts are ROHS3 compliant and carry EAR99 ECCN classification.

Substitution is valid when the application electrical requirements fall within the E203MD1AV2BE ratings: 0.4VA at 20V AC/DC. Applications requiring the full 5A AC or 4A DC ratings of the SWW249A7 cannot use this substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the SWW249A7 and E203MD1AV2BE are active production parts with ROHS3 compliance and EAR99 ECCN classification, meeting regulatory requirements for industrial applications.

Selection between these parts is determined by electrical load requirements. The SWW249A7 is specified for applications requiring 5A AC at 125V or 4A DC at 30V. The E203MD1AV2BE is suitable only for applications with electrical loads not exceeding 0.4VA at 20V AC or DC.

The E203MD1AV2BE provides additional environmental protection with IP57 ingress rating and extended low-temperature operation to -30°C, making it suitable for sealed or outdoor applications within its power rating.

Frequently Asked Questions (FAQ)

Q: Can E203MD1AV2BE replace SWW249A7 in all applications?

A: No. Substitution is valid only when the application electrical load does not exceed 0.4VA at 20V AC/DC. Applications requiring the full 5A AC or 4A DC ratings of the SWW249A7 cannot use the E203MD1AV2BE.

Q: Are the actuator lengths compatible?

A: Yes. The SWW249A7 actuator length is 7.50mm and the E203MD1AV2BE is 7.62mm. This 0.12mm difference is mechanically compatible for standard through-hole mounting applications.

Q: What is the difference in ingress protection?

A: The SWW249A7 ingress protection rating is not specified. The E203MD1AV2BE provides IP57 protection (dust protected and waterproof). If environmental sealing is required, the E203MD1AV2BE offers this advantage within its power rating.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SWW249A7 and E203MD1AV2BE are ROHS3 compliant with EAR99 ECCN classification. The E203MD1AV2BE is REACH Affected while the SWW249A7 is REACH Unaffected.

Q: What is the electrical life expectancy for both parts?

A: Both parts are rated for 40,000 electrical cycles, providing equivalent operational longevity.

Q: Can SWW249A7 be used in place of E203MD1AV2BE?

A: Yes. The SWW249A7 can replace the E203MD1AV2BE in any application. However, the SWW249A7 does not provide the IP57 ingress protection of the E203MD1AV2BE and has a narrower low-temperature operating range (-20°C minimum vs -30°C).
