B13AB-GA Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The B13AB-GA is an NKK Switches toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 0.4VA at 28V AC/DC. This through-hole mounted component features an On-Off-On switch function with a standard round actuator and non-illuminated design. The part is Active in product status and RoHS3 compliant, making it suitable for industrial control and switching applications requiring reliable electromechanical performance.

Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

The ET03SD1CBE from C&K is identified as a substitute for the B13AB-GA based on the following critical parameters that determine functional interchangeability:

Matching Parameters:

• Circuit configuration: Both are SPDT
• Switch function: Both are On-Off-On
• Current rating: Both are 0.4VA (AC/DC)
• Mounting type: Both are through-hole
• Actuator type: Both are standard round
• Termination style: Both are PC Pin
• Operating temperature range: Both are -30°C to 85°C
• RoHS compliance: Both are RoHS3 compliant

Differing Parameters:

• Voltage rating: B13AB-GA is rated 28V; ET03SD1CBE is rated 20V
• Actuator length: B13AB-GA is 10.00mm; ET03SD1CBE is 10.16mm
• Electrical life: B13AB-GA is 50,000 cycles; ET03SD1CBE is 30,000 cycles
• Ingress protection: B13AB-GA has no rating; ET03SD1CBE is IP57
• Actuator material: B13AB-GA uses brass with nickel plating; ET03SD1CBE uses brass with chrome plating

The ET03SD1CBE is suitable as a substitute when the application voltage does not exceed 20V and the lower electrical life rating of 30,000 cycles is acceptable for the intended duty cycle.

Parameter Comparison

Engineering Selection Recommendations

Both the B13AB-GA and ET03SD1CBE are Active products with RoHS3 compliance and REACH status documentation. Selection between these parts depends on application-specific voltage and duty cycle requirements.

The B13AB-GA is the primary choice for applications requiring 28V operation or extended electrical life beyond 30,000 cycles. The ET03SD1CBE is suitable for applications operating at 20V or below and where the 30,000-cycle electrical life rating meets the design specification. The ET03SD1CBE provides additional environmental protection through IP57 ingress rating, making it suitable for applications with moisture or dust exposure.

Actuator length difference of 0.16mm between the two parts must be verified against panel cutout and mechanical assembly constraints before substitution.

Frequently Asked Questions (FAQ)

Q: Can the ET03SD1CBE replace the B13AB-GA in a 28V circuit?

A: No. The ET03SD1CBE is rated for maximum 20V operation. Using it in a 28V circuit exceeds its voltage rating and will result in component failure or unsafe operation.

Q: What is the significance of the 20,000-cycle difference in electrical life?

A: The B13AB-GA is rated for 50,000 electrical cycles while the ET03SD1CBE is rated for 30,000 cycles. For applications with high switching frequency or long service life requirements, the B13AB-GA provides extended operational durability. The ET03SD1CBE is suitable for applications where the cumulative switching cycles remain below 30,000 over the product lifetime.

Q: Are the actuator lengths interchangeable?

A: The actuator lengths differ by 0.16mm (B13AB-GA at 10.00mm, ET03SD1CBE at 10.16mm). This difference must be evaluated against panel thickness and mechanical clearance requirements. Verify that the slightly longer actuator of the ET03SD1CBE does not interfere with panel-mounted components or enclosure geometry.

Q: Do both parts meet the same environmental standards?

A: Both parts are RoHS3 compliant and operate across the same temperature range (-30°C to 85°C). The ET03SD1CBE provides additional environmental protection with IP57 ingress rating, suitable for applications exposed to dust or moisture. The B13AB-GA has no specified ingress protection rating.

Q: What is the difference between the actuator materials?

A: The B13AB-GA uses brass with nickel plating, while the ET03SD1CBE uses brass with chrome plating. Both materials provide corrosion resistance and electrical conductivity suitable for switch applications. Material selection does not affect functional interchangeability for standard switching applications.
