BDB06 DIP Switch - Equivalent & Substitute Parts

Part Overview

The BDB06 is a 6-position DIP switch manufactured by C&K, featuring SPST (Single Pole Single Throw) circuit configuration with slide actuator and through-hole mounting. This component is rated for 25mA at 25VDC and is designed for applications requiring standard vertical profile DIP switch functionality.

The BDB06 has reached obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BDB06 is determined by the following critical parameters:

• Circuit Configuration: SPST topology must be maintained
• Position Count: 6-position requirement
• Mounting Interface: Through-hole with 0.100" (2.54mm) pitch
• Actuator Style: Slide actuator (standard profile)
• Electrical Ratings: Current and voltage ratings must meet or exceed application requirements
• Physical Envelope: Height above board and overall length compatibility
• Compliance: RoHS3 compliance required

The BD06 qualifies as a substitute based on matching circuit type, position count, mounting configuration, pitch, and actuator style. Electrical rating differences (100mA at 5VDC versus 25mA at 25VDC) require application-level verification to ensure compatibility with specific circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

The BD06 is the primary substitute for the obsolete BDB06. Both components share identical mechanical interfaces, circuit topology, and position configuration. The BD06 maintains active product status with ROHS3 compliance, ensuring long-term supply chain availability and regulatory alignment.

Key considerations for selection:

• Electrical Rating Compatibility: The BD06 operates at 5VDC with 100mA capacity, differing from the BDB06's 25VDC/25mA specification. Applications must operate within the BD06's electrical envelope.
• Physical Fit: Height above board increases from 0.274" to 0.297", a 0.023" (0.59mm) difference. PCB layout clearance must accommodate this variance.
• Body Material Difference: BDB06 uses Polyamide (PA46), while BD06 uses Polybutylene Terephthalate (PBT) glass-filled. Both materials support washable assembly processes.
• Compliance Status: BD06 includes REACH Unaffected designation, providing additional regulatory documentation.

Frequently Asked Questions (FAQ)

Q: Can the BD06 directly replace the BDB06 in all applications?

A: Direct replacement requires verification that the application operates within the BD06's electrical ratings (5VDC, 100mA). The mechanical interface is compatible, but electrical circuit requirements must be evaluated.

Q: What is the significance of the height difference between BDB06 and BD06?

A: The BD06 is 0.023" (0.59mm) taller. PCB designs with tight vertical clearance constraints must confirm adequate space above the component. Standard DIP switch layouts typically accommodate this variance.

Q: Are both parts washable?

A: Yes. Both BDB06 and BD06 support washable assembly processes, maintaining compatibility with standard manufacturing workflows.

Q: What compliance certifications apply to the BD06?

A: The BD06 is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Q: Why is the BDB06 obsolete?

A: Product status reflects manufacturer discontinuation. The BD06 represents the active equivalent within C&K's DIP switch portfolio.

Q: Are there differences in contact material or finish?

A: No. Both parts use phosphor bronze contacts with gold finish, ensuring consistent electrical performance and reliability characteristics.
