BD12AV DIP Switch SPST 12 Position Equivalent & Substitute Parts

Part Overview

The BD12AV is a DIP switch manufactured by C&K, featuring a 12-position SPST configuration with a slide actuator rated for 100mA at 5VDC. This component is designed for through-hole, right-angle mounting applications requiring reliable switching functionality in compact form factors. The product maintains active status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical and mechanical parameters align with application requirements, enabling component sourcing flexibility while maintaining circuit performance.

Key Parameters

Substitute Part Grouping Explanation

The 206-12RAST from CTS Electrocomponents is identified as a substitute based on the following alignment criteria:

Matching Parameters:

• Circuit configuration: SPST
• Number of positions: 12
• Actuator type: Slide (Standard)
• Mounting type: Through Hole, Right Angle
• Pitch: 0.100" (2.54mm)
• Contact finish: Gold
• Termination style: PC Pin
• Washable design: Yes
• RoHS3 compliance: Yes
• Active product status: Yes

Differing Parameters: The 206-12RAST operates at 50mA/24VDC versus the BD12AV's 100mA/5VDC specification. This difference requires application-level verification to ensure the substitute meets circuit voltage and current requirements. The substitute features a slightly increased height (0.400" vs 0.380") and extended operating temperature range (-55°C to 85°C vs -40°C to 85°C).

Parameter Comparison

Engineering Selection Recommendations

Both the BD12AV and 206-12RAST maintain active product status with full RoHS3 compliance and REACH unaffected certification, ensuring regulatory alignment for current manufacturing environments. Selection between these components depends on circuit voltage and current specifications. The BD12AV is specified for 5VDC/100mA applications, while the 206-12RAST operates at 24VDC/50mA. The 206-12RAST provides extended low-temperature operation (-55°C minimum) compared to the BD12AV (-40°C minimum), offering advantage in cold-environment applications. Both components feature identical 12-position SPST configuration, 0.100" pitch, gold-plated contacts, and 10,000-cycle electrical life, supporting direct mechanical and electrical interface compatibility within voltage and current constraints.

Frequently Asked Questions (FAQ)

Q: Can the 206-12RAST replace the BD12AV in any application?

A: Substitution is valid only when the circuit operates at 24VDC and requires 50mA or less. The BD12AV is rated for 5VDC/100mA; the 206-12RAST is rated for 24VDC/50mA. Voltage and current specifications must align with application requirements.

Q: Are the physical dimensions compatible?

A: Both components feature identical 0.100" (2.54mm) pitch and through-hole, right-angle mounting. The 206-12RAST height is 0.400" versus the BD12AV at 0.380", a 0.020" difference that may affect PCB layout clearance in space-constrained designs.

Q: Do both parts meet current compliance requirements?

A: Yes. Both the BD12AV and 206-12RAST are RoHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification. Both maintain active product status.

Q: What is the mechanical life expectancy?

A: The BD12AV specifies 10,000 mechanical cycles. The 206-12RAST does not provide mechanical life data in available documentation; electrical life is rated at 10,000 cycles for both components.

Q: Are there temperature range considerations for substitution?

A: The 206-12RAST operates from -55°C to 85°C, extending the low-temperature range by 15°C compared to the BD12AV (-40°C to 85°C). Both share the 85°C upper limit. Application temperature requirements determine if this difference is relevant.
