SWW238CD7 Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The SWW238CD7 is an APEM Inc. toggle switch featuring SPDT (Single Pole Double Throw) circuitry with 0.4VA current rating at 20V AC/DC. This through-hole, right-angle vertical mounted switch is designed for on-off-momentary applications and is currently active in production. Alternative equivalent parts may be required due to inventory constraints, regional availability, or specific application requirements such as enhanced ingress protection or extended temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

The E107MD1AV2BE from C&K qualifies as a direct substitute for the SWW238CD7 based on the following critical parameters:

• Circuit Configuration: Both parts feature identical SPDT circuitry
• Electrical Ratings: Matching 0.4VA current rating and 20V AC/DC voltage specifications
• Mounting Configuration: Both are through-hole, right-angle vertical mounted switches
• Switch Function: Both support on-off-momentary operation
• Actuator Type: Both utilize standard round actuators
• Termination: Both employ PC pin termination style
• Compliance: Both are ROHS3 compliant

Substitution is valid within the electrical and mechanical constraints defined by these parameters. Differences in actuator length, operating temperature range, electrical life cycles, and ingress protection rating do not prevent functional equivalence in applications where the SWW238CD7 specifications are met.

Parameter Comparison

Engineering Selection Recommendations

Both the SWW238CD7 and E107MD1AV2BE are active production parts with ROHS3 compliance. Selection between these parts should be based on application-specific requirements:

The SWW238CD7 is suitable for standard applications within the -20°C to 85°C operating range with a specified electrical life of 50,000 cycles.

The E107MD1AV2BE offers extended low-temperature operation (-30°C minimum) and IP57 ingress protection, making it applicable to environments requiring dust and water resistance. The electrical life specification of 40,000 cycles is lower than the SWW238CD7.

Both parts meet the core electrical and mechanical requirements for SPDT toggle switch applications at 0.4VA and 20V ratings. Packaging format differs (bulk versus tray), which may influence procurement and assembly workflows.

Frequently Asked Questions (FAQ)

Q: Can the E107MD1AV2BE replace the SWW238CD7 in existing designs?

A: Yes, the E107MD1AV2BE is electrically and mechanically equivalent for applications requiring SPDT switching at 0.4VA and 20V. The 0.12mm difference in actuator length (7.62mm versus 7.50mm) and packaging format (tray versus bulk) are the primary physical differences. Verify panel cutout compatibility and assembly procedures before implementation.

Q: What are the key substitution criteria for these parts?

A: Substitution validity is determined by matching SPDT circuit configuration, 0.4VA current rating, 20V AC/DC voltage specifications, through-hole right-angle vertical mounting, on-off-momentary function, standard round actuator type, and PC pin termination. Both parts satisfy these criteria.

Q: Does the IP57 rating on the E107MD1AV2BE affect compatibility?

A: The IP57 ingress protection rating on the E107MD1AV2BE is an additional feature that does not prevent substitution. It indicates enhanced sealing against dust and water ingress. Applications not requiring this protection level can use either part without functional impact.

Q: Are there temperature range considerations for substitution?

A: The E107MD1AV2BE operates from -30°C to 85°C, while the SWW238CD7 operates from -20°C to 85°C. For applications requiring operation below -20°C, the E107MD1AV2BE is the appropriate selection. For standard temperature ranges, both parts are equivalent.

Q: How do electrical life specifications affect part selection?

A: The SWW238CD7 is rated for 50,000 electrical cycles, while the E107MD1AV2BE is rated for 40,000 cycles. For high-cycle applications approaching or exceeding 40,000 cycles, the SWW238CD7 provides additional operational margin. Both parts are suitable for typical industrial switching applications.
