S236CDB7 Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The S236CDB7 is an APEM Inc. toggle switch featuring SPDT (Single Pole Double Throw) circuitry with On-On switching function. This panel mount component is rated for 0.4VA at 20V AC/DC operation and is designed for applications requiring reliable electromechanical switching with epoxy sealed terminals. The part maintains Active product status with 1134 units in current inventory. Substitute parts are identified when original stock becomes unavailable or when application requirements necessitate alternative mounting configurations or environmental ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S236CDB7 is determined by the following critical parameters:

• Circuit Configuration: Must be SPDT to maintain identical switching logic
• Switch Function: Must be On-On to preserve operational behavior
• Current Rating: Must support minimum 0.4VA at rated voltage
• Voltage Rating: Must support minimum 20V AC and 20V DC
• Termination Style: Must be PC Pin for circuit board compatibility
• RoHS Compliance: Must maintain ROHS3 Compliant status for regulatory alignment

The E101MD1CBE from C&K meets these core electrical and functional requirements. Differences in mounting type (Through Hole vs. Panel Mount), actuator length, environmental protection rating, and electrical life cycle rating represent design trade-offs that do not prevent functional substitution when application constraints permit.

Parameter Comparison

Engineering Selection Recommendations

Both the S236CDB7 and E101MD1CBE maintain Active product status and ROHS3 compliance, supporting continued use in regulated applications. The S236CDB7 offers extended low-temperature operation (-40°C minimum) and higher electrical life rating (50,000 cycles), making it preferable for demanding thermal or high-cycle applications. The E101MD1CBE provides IP57 ingress protection (dust and waterproof) and Through Hole mounting, suitable for applications requiring enhanced environmental sealing or PCB-mounted configurations. Selection between these parts depends on whether panel mount or through-hole integration, temperature range, and environmental protection requirements take precedence in the application design.

Frequently Asked Questions (FAQ)

Q: Can E101MD1CBE replace S236CDB7 in all applications?

A: Electrical substitution is valid when circuit requirements match: SPDT configuration, On-On function, 0.4VA at 20V, and PC Pin termination. Physical integration differs due to mounting type (Through Hole vs. Panel Mount), requiring mechanical redesign. Temperature range and electrical life differences must be evaluated against application specifications.

Q: What are the key differences between these parts?

A: The S236CDB7 is panel mount with -40°C to 85°C operation and 50,000 cycle life. The E101MD1CBE is through-hole mount with -30°C to 85°C operation, 40,000 cycle life, and IP57 environmental protection. Both share identical electrical ratings and termination style.

Q: Does the lower electrical life of E101MD1CBE affect substitution eligibility?

A: Electrical life difference (40,000 vs. 50,000 cycles) represents a design parameter variance. Substitution validity depends on application cycle requirements. If the application demands exceed 40,000 cycles, the E101MD1CBE does not meet performance specifications.

Q: Are there packaging differences between these parts?

A: S236CDB7 ships in Bulk packaging; E101MD1CBE ships in Tray packaging. This affects supply chain handling and inventory management but does not impact electrical or functional compatibility.

Q: What does the IP57 rating on E101MD1CBE provide?

A: IP57 classification indicates dust protection and waterproof operation. This environmental rating is not present on the S236CDB7, making the E101MD1CBE suitable for applications requiring enhanced moisture or contamination resistance.
