BDB07 DIP Switch - Equivalent & Substitute Parts

Part Overview

The BDB07 is a 7-position DIP switch manufactured by C&K, designed for through-hole mounting applications requiring SPST (Single Pole Single Throw) switching functionality. This component operates at 25mA and 25VDC with a standard slide actuator and raised profile. The BDB07 is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BDB07 is determined by the following critical parameters:

• Circuit Configuration: Must remain SPST to maintain switching logic compatibility
• Number of Positions: Must be 7 to match the original switch configuration
• Mounting Type: Must be through-hole to ensure PCB compatibility without redesign
• Pitch: Must be 0.100" (2.54mm) to maintain footprint alignment
• Actuator Type: Must be slide (standard) to preserve user interface consistency
• Operating Temperature Range: Must encompass or match the -40°C to 85°C specification
• Electrical and Mechanical Life: Must meet or exceed 10,000 cycles

The BD07 qualifies as a substitute based on these core parameters. While electrical ratings differ (100mA at 5VDC versus 25mA at 25VDC), the BD07 operates within compatible power domains for typical digital logic applications and maintains all mechanical and functional specifications required for direct replacement.

Engineering Selection Recommendations

The BD07 is the designated substitute for the obsolete BDB07 based on the following criteria:

• Product Status: The BD07 is actively manufactured by C&K, ensuring long-term availability and supply chain continuity for the BDB07's obsolete status.
• Regulatory Compliance: Both parts maintain ROHS3 compliance, satisfying environmental and regulatory requirements for new designs and legacy system support.
• Functional Equivalence: Identical circuit configuration (SPST), position count (7), mounting type (through-hole), and pitch (0.100") ensure direct PCB compatibility without layout modifications.
• Mechanical Compatibility: Matching actuator type, contact materials, and termination style preserve user interface consistency and electrical performance characteristics.
• Thermal Performance: Identical operating temperature range (-40°C to 85°C) and mechanical/electrical life ratings (10,000 cycles) maintain reliability specifications.

Voltage and Current Considerations: The BD07 operates at 5VDC with 100mA rating versus the BDB07's 25VDC at 25mA. Selection depends on the application's power domain. For 5V logic-level switching applications, the BD07 is directly suitable. For 25V applications, verify that the BD07's 5VDC rating aligns with system requirements or confirm that the application can operate within the lower voltage specification.

Physical Clearance: The BD07 has a height of 0.297" (7.54mm) compared to the BDB07's 0.274" (6.95mm). Verify 0.023" additional clearance above the PCB in the target assembly.

Frequently Asked Questions (FAQ)

Q: Can the BD07 directly replace the BDB07 without PCB modifications?

A: Yes, for mechanical and electrical interface compatibility. Both parts share identical pitch (0.100"), mounting type (through-hole), length (0.780"), and PC pin termination. However, verify that the additional 0.023" height of the BD07 does not conflict with enclosure or component clearances.

Q: What is the primary difference between the BDB07 and BD07?

A: The voltage and current ratings differ. The BDB07 is rated for 25VDC at 25mA, while the BD07 is rated for 5VDC at 100mA. Both maintain identical switching functionality (SPST, 7-position) and mechanical specifications. Selection depends on the application's power domain.

Q: Is the BD07 suitable for 25V applications originally designed for the BDB07?

A: The BD07 is rated for 5VDC maximum. Applications requiring 25VDC operation must verify that system voltage can be reduced to 5VDC or identify alternative substitutes rated for higher voltages. Do not exceed the BD07's 5VDC rating.

Q: Are there packaging differences between the BDB07 and BD07?

A: The BDB07 is specified with "-" packaging, while the BD07 is supplied in tube packaging. Both are through-hole components with identical electrical and mechanical interfaces. Tube packaging is standard for active production parts.

Q: Why is the BDB07 classified as obsolete?

A: The BDB07 has been discontinued by C&K. The BD07 is the active production equivalent, ensuring continued availability for replacement and new design applications.

Q: Do both parts meet RoHS compliance requirements?

A: Yes, both the BDB07 and BD07 are ROHS3 compliant, satisfying environmental and regulatory requirements for electronic component use.

Q: What is the mechanical life expectancy for the BD07?

A: The BD07 is rated for 10,000 mechanical cycles and 10,000 electrical cycles, matching the BDB07 specification and ensuring equivalent reliability for switching applications.
