DS08 DIP Switch SPST 8-Position Equivalent & Substitute Parts

Part Overview

The DS08 is an 8-position DIP switch manufactured by APEM Inc., designed for through-hole mounting applications requiring single-pole single-throw (SPST) switching at 50mA and 24VDC. This component features a slide actuator with raised level, phosphor bronze contacts finished in gold, and is sealed with epoxy-coated terminals for enhanced reliability.

The DS08 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for legacy systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

The CTS Electrocomponents 208-8 qualifies as a functional substitute for the DS08 based on the following critical parameters:

• Circuit Configuration: Both parts are SPST (single-pole single-throw)
• Number of Positions: Both provide 8-position switching
• Current Rating: Both rated at 50mA
• Voltage Rating: Both rated at 24VDC
• Actuator Type: Both feature slide (standard) actuators with raised levels
• Mounting Type: Both are through-hole mounted
• Pitch: Both use 0.100" (2.54mm) full pitch
• Termination Style: Both use PC pin termination
• Compliance: Both are ROHS3 compliant and REACH unaffected

These parameters define the functional and mechanical compatibility required for direct substitution in applications designed for the DS08.

Engineering Selection Recommendations

The CTS Electrocomponents 208-8 is the identified substitute for the obsolete DS08. Selection of the 208-8 is supported by:

• Functional Equivalence: Identical circuit configuration, switching positions, current and voltage ratings ensure direct functional replacement
• Mechanical Compatibility: Matching pitch, termination style, and through-hole mounting enable direct PCB layout compatibility
• Compliance Alignment: Both parts meet ROHS3 and REACH requirements, maintaining regulatory compliance in replacement designs
• Active Product Status: The 208-8 is currently in active production, ensuring long-term supply availability and support

Design Consideration: The 208-8 exhibits a greater height above board (0.334" versus 0.271") and an extended operating temperature range (-55°C to 85°C versus -20°C to 70°C). Verify that the increased height does not conflict with enclosure or component clearance constraints in the target application. The extended temperature range of the 208-8 provides additional operational margin for applications subject to wider environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can the CTS 208-8 be used as a direct replacement for the DS08 in existing designs?

A: Yes. The 208-8 matches all critical functional and mechanical parameters: SPST circuit, 8 positions, 50mA/24VDC ratings, slide actuator, through-hole mounting, and 0.100" pitch. PCB layouts designed for the DS08 will accommodate the 208-8 without modification.

Q: What is the primary difference between the DS08 and 208-8?

A: The 208-8 has a greater height above board (0.334" versus 0.271") and a wider operating temperature range (-55°C to 85°C versus -20°C to 70°C). Verify clearance in your enclosure before substitution.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the DS08 and 208-8 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the packaging difference between these parts?

A: The DS08 is supplied in standard packaging, while the 208-8 is supplied in tube packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Do both parts have the same electrical life rating?

A: Yes. Both the DS08 and 208-8 are rated for 2,000 electrical cycles, providing equivalent reliability in switching applications.

Q: Is the 208-8 suitable for applications requiring the full operating temperature range of the DS08?

A: Yes. The 208-8 operating range (-55°C to 85°C) encompasses the DS08 range (-20°C to 70°C), ensuring compatibility for all temperature conditions specified for the original design.
