SW236A7 Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The SW236A7 is an APEM Inc. toggle switch featuring SPDT (Single Pole Double Throw) circuitry 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 suitable for industrial applications. The part is currently active in production with 730 units in stock. Alternative components may be required due to inventory constraints, application-specific performance requirements, or design optimization needs.

Key Parameters

Substitute Part Grouping Explanation

The E101MD1AQE from C&K qualifies as a direct substitute based on the following critical parameters:

Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-On
• Mounting type: Through hole, right angle
• Actuator type: Standard round
• Termination style: PC pin
• Voltage rating (AC): 125V
• Electrical life: 40,000 cycles
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Enhanced Specifications: The E101MD1AQE provides higher current capacity (7.5A AC/DC versus 5A AC/4A DC), improved ingress protection (IP57), extended operating temperature range (-30°C to 85°C), and epoxy-sealed terminals for enhanced environmental resistance.

Parameter Comparison

Engineering Selection Recommendations

Both components meet ROHS3 compliance requirements and maintain MSL 1 (Unlimited) moisture sensitivity ratings, suitable for standard manufacturing and storage conditions.

The SW236A7 remains the primary specification when current requirements do not exceed 5A AC or 4A DC, and when operating temperatures remain within the -20°C to 85°C range.

The E101MD1AQE serves as a qualified substitute when higher current capacity is required, extended low-temperature operation is necessary, or enhanced environmental sealing (IP57) is specified. The 0.12mm difference in actuator length (7.62mm versus 7.50mm) is within typical mechanical tolerance for through-hole right-angle mounting applications.

Frequently Asked Questions (FAQ)

Q: Can E101MD1AQE replace SW236A7 in all applications? A: Yes, provided the application does not require the specific DC voltage rating of 30V. The E101MD1AQE is rated for 28V DC, which is acceptable for most standard DC applications but should be verified against circuit requirements.

Q: What is the significance of the actuator length difference? A: The 0.12mm difference (7.50mm to 7.62mm) is negligible for through-hole mounting and does not affect panel cutout compatibility or mechanical fit in standard applications.

Q: Does packaging format affect electrical performance? A: No. The SW236A7 is supplied in bulk packaging while the E101MD1AQE is supplied in tray packaging. Both formats contain identical electrical components; packaging selection depends on inventory management and handling requirements.

Q: Why does E101MD1AQE have higher current ratings? A: The E101MD1AQE incorporates epoxy-sealed terminals and enhanced contact materials (chrome-plated brass versus nickel-plated brass), enabling higher current capacity while maintaining the same 40,000-cycle electrical life.

Q: Are both parts suitable for sealed or waterproof applications? A: The SW236A7 features sealed design. The E101MD1AQE provides IP57 ingress protection (dust protected, waterproof), making it suitable for more demanding environmental conditions.
