BDB10 Equivalent & Substitute Parts

Part Overview

The BDB10 is a DIP 10-position SPST slide switch manufactured by C&K, designed for through-hole mounting applications. This component features a standard vertical profile with raised actuator, phosphor bronze contacts with gold finish, and is rated for 25mA at 25VDC. The BDB10 is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BDB10 is determined by the following critical parameters:

• Circuit configuration (SPST)
• Number of positions (10)
• Mounting type (Through Hole)
• Pitch spacing (0.100" / 2.54mm)
• Actuator type (Slide, Standard)
• Contact material and finish (Phosphor Bronze, Gold)
• Operating temperature range (-40°C ~ 85°C)
• RoHS compliance (ROHS3)

The BD10 meets all these core substitution criteria. While the BD10 operates at different electrical ratings (100mA at 5VDC versus 25mA at 25VDC), it maintains mechanical and physical compatibility with the BDB10 footprint and interface requirements. The BD10 is classified as active product status, providing ongoing availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The BD10 is the direct equivalent substitute for the BDB10. Both components share identical mechanical interfaces, footprint compatibility, and environmental specifications. The BD10 is currently in active production status, ensuring long-term availability and supply chain reliability compared to the obsolete BDB10.

Selection of the BD10 as a replacement maintains compliance with ROHS3 requirements and preserves the operating temperature range of -40°C to 85°C. The component is suitable for applications requiring through-hole DIP switch functionality with standard slide actuation and gold-plated phosphor bronze contacts.

Frequently Asked Questions (FAQ)

Q: Can the BD10 be used as a direct replacement for the BDB10 in existing designs?

A: Yes. The BD10 maintains identical mechanical dimensions, pitch spacing (0.100"), mounting type (through-hole), and contact configuration. Both components use the same PC pin termination style and are compatible with standard DIP switch footprints.

Q: What are the differences between the BDB10 and BD10?

A: The primary differences are electrical ratings and product status. The BDB10 is rated for 25mA at 25VDC and is obsolete. The BD10 is rated for 100mA at 5VDC and is in active production. Both share identical mechanical specifications, operating temperature range, and lifecycle ratings.

Q: Are there any body material differences between these parts?

A: Yes. The BDB10 uses Polyamide (PA46) Nylon 4/6, while the BD10 uses Polybutylene Terephthalate (PBT) Glass Filled. Both materials are suitable for the specified operating temperature range and environmental conditions.

Q: Does the BD10 maintain the same height above board as the BDB10?

A: The BD10 height is 0.297" (7.54mm) compared to the BDB10 at 0.274" (6.95mm). This represents a 0.023" (0.59mm) difference. Verify clearance in applications with height-constrained layouts.

Q: Are both components RoHS compliant?

A: Yes. Both the BDB10 and BD10 are ROHS3 compliant and have Moisture Sensitivity Level 1 (Unlimited), suitable for standard manufacturing and storage conditions.
