DS12 DIP Switch SPST 12 Position Equivalent & Substitute Parts

Part Overview

The DS12 is a 12-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 terminals for reliability.

The DS12 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for legacy systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS12 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST (single-pole single-throw)
• Number of Positions: Must be 12
• Current Rating: Must support minimum 50mA
• Voltage Rating: Must support minimum 24VDC
• Mounting Type: Must be through-hole compatible
• Pitch: Must be 0.100" (2.54mm) for PCB alignment
• Termination Style: Must use PC Pin termination

The substitute part CTS Electrocomponents 208-12 meets all critical substitution criteria. Both parts share identical circuit configuration, position count, current and voltage ratings, mounting type, pitch, and termination style. These parameters ensure mechanical and electrical compatibility in the target application.

Parameter Comparison

Engineering Selection Recommendations

The CTS Electrocomponents 208-12 is a direct functional substitute for the obsolete DS12. Both components satisfy identical electrical requirements and share compatible mechanical interfaces.

Compliance Considerations: Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component procurement.

Product Status: The 208-12 is classified as active, ensuring ongoing availability and supply chain support. The DS12 is obsolete, making the 208-12 the appropriate selection for new designs or component replenishment.

Physical Dimensions: The 208-12 exhibits slightly larger height above board (0.334" versus 0.271") and length (1.286" versus 1.259"). These dimensional differences are minor and should be evaluated against specific PCB layout constraints in the target application.

Operating Temperature: The 208-12 supports an extended operating temperature range (-55°C to 85°C) compared to the DS12 (-20°C to 70°C), providing greater thermal margin in demanding environments.

Frequently Asked Questions (FAQ)

Q: Can the CTS 208-12 replace the APEM DS12 in existing designs?

A: Yes. Both components share identical circuit configuration (SPST), position count (12), current rating (50mA), voltage rating (24VDC), pitch (0.100"), and termination style (PC Pin). Electrical and mechanical compatibility is confirmed. Physical dimensions differ slightly; verify PCB layout clearances before implementation.

Q: What is the primary reason for substitution?

A: The DS12 is obsolete. The 208-12 is an active product from CTS Electrocomponents, ensuring supply availability and long-term component sourcing.

Q: Are there compliance differences between these parts?

A: No. Both parts are ROHS3 compliant and REACH unaffected. Regulatory compliance is equivalent.

Q: How do the operating temperature ranges differ?

A: The DS12 operates from -20°C to 70°C. The 208-12 operates from -55°C to 85°C. The 208-12 provides extended thermal operating range, beneficial for applications exposed to extreme temperatures.

Q: What packaging is available for the 208-12?

A: The 208-12 is supplied in tube packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Are the mechanical life specifications comparable?

A: The DS12 specifies 5,000 mechanical cycles. The 208-12 does not provide mechanical life data in available documentation. Both specify 2,000 electrical cycles, which is the controlling parameter for electrical switching applications.
