SW236AD7 Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The SW236AD7 is an SPDT (Single Pole Double Throw) toggle switch manufactured by APEM Inc., designed for through-hole, right-angle mounting applications. This switch is rated for 4A DC at 30V with a sealed design and 40,000 electrical cycle life. The product is currently active and ROHS3 compliant. Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameters of this switch category, particularly when the main part faces inventory constraints or application-specific requirements necessitate alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

The 100AWSP1T2B4M6RE from E-Switch is identified as a substitute based on the following critical parameters that define functional equivalence within SPDT toggle switch applications:

Matching Parameters:

• Circuit configuration: SPDT (Single Pole Double Throw)
• Switch function: On-On
• Mounting type: Through Hole, Right Angle
• Actuator type: Standard Round
• Termination style: PC Pin
• RoHS compliance: ROHS3 Compliant
• Product status: Active

Allowable Variations: The substitute part operates within acceptable parameter ranges for this switch category. The 100AWSP1T2B4M6RE is rated for 0.4VA (AC/DC) at 20V, which represents a lower power envelope compared to the SW236AD7. This substitution is valid for applications where the actual load requirements do not exceed the substitute's electrical ratings. The actuator length differs by 0.12mm (7.62mm vs. 7.50mm), which falls within mechanical tolerance for standard round actuator designs. Operating temperature range extends to -30°C (lower than -20°C), providing broader environmental coverage. Electrical life is rated at 30,000 cycles versus 40,000 cycles on the main part.

Parameter Comparison

Engineering Selection Recommendations

Both the SW236AD7 and 100AWSP1T2B4M6RE are active products with ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards. Selection between these parts must be based on application-specific electrical requirements. The SW236AD7 is suitable for applications requiring 4A DC switching at 30V with extended electrical life (40,000 cycles). The 100AWSP1T2B4M6RE is appropriate for lower-power applications operating at 20V or below with AC/DC compatibility. Both parts feature sealed or epoxy-sealed terminal designs, supporting use in environments requiring ingress protection. The mechanical compatibility of both parts (through-hole, right-angle mounting with standard round actuators) ensures interchangeability at the board level when electrical ratings align with application demands.

Frequently Asked Questions (FAQ)

Q: Can the 100AWSP1T2B4M6RE directly replace the SW236AD7 in all applications?

A: Direct replacement is valid only when the application's actual electrical load does not exceed 0.4VA at 20V DC. If your circuit requires the full 4A at 30V capability of the SW236AD7, the substitute part is not suitable.

Q: What are the key differences in electrical ratings between these parts?

A: The SW236AD7 is rated for 4A DC at 30V, while the 100AWSP1T2B4M6RE is rated for 0.4VA (AC/DC) at 20V. This represents a significant difference in power handling capacity. Verify your application's actual voltage and current requirements before substitution.

Q: Are the physical dimensions compatible for PCB mounting?

A: Both parts use through-hole, right-angle mounting with PC pin termination. The actuator length differs by 0.12mm (7.50mm vs. 7.62mm), which is within standard mechanical tolerance for toggle switch designs and does not affect board-level compatibility.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the SW236AD7 and 100AWSP1T2B4M6RE are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing.

Q: What is the difference in electrical life between these switches?

A: The SW236AD7 is rated for 40,000 electrical cycles, while the 100AWSP1T2B4M6RE is rated for 30,000 cycles. For applications with high switching frequency, the SW236AD7 provides extended operational life.

Q: Can the 100AWSP1T2B4M6RE be used in lower temperature environments?

A: Yes. The 100AWSP1T2B4M6RE operates from -30°C to 85°C, compared to the SW236AD7's -20°C to 85°C range. The substitute part provides broader low-temperature coverage.
