DS05 DIP Switch SPST 5 Position Equivalent & Substitute Parts

Part Overview

The DS05 is a slide-actuated DIP switch manufactured by APEM Inc., configured as a single-pole single-throw (SPST) switch with 5 positions. It is rated for 50mA at 24VDC and designed for through-hole mounting on printed circuit boards. The DS05 is classified as obsolete, making identification of equivalent substitute parts essential for ongoing production support, maintenance, and design updates. Equivalent parts must maintain functional compatibility across electrical ratings, mechanical dimensions, and mounting characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS05 is determined by strict equivalence across the following critical parameters:

• Circuit topology: SPST configuration with 5 discrete positions
• Electrical ratings: 50mA current capacity and 24VDC voltage rating
• Mechanical interface: Through-hole mounting with 0.100" (2.54mm) pitch and PC pin termination
• Actuator mechanism: Slide-type actuator with raised actuator level
• Compliance standards: ROHS3 compliance and EAR99 export classification

The CTS Electrocomponents 208-5 meets all critical substitution criteria. Both parts share identical circuit configuration, electrical ratings, mounting type, pitch, and termination style. Differences in height above board, body material, and contact finish do not preclude functional substitution when the electrical and mechanical interface requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

The CTS Electrocomponents 208-5 is a direct functional substitute for the obsolete APEM Inc. DS05. Both parts satisfy identical electrical and mechanical interface requirements for 24VDC, 50mA SPST switching applications with 5-position configuration.

Product Status Consideration: The DS05 is obsolete with limited inventory (775 pcs). The 208-5 is active with substantial inventory availability (18,969 pcs), ensuring long-term supply chain continuity.

Compliance: Both parts are ROHS3 compliant and carry EAR99 export classification, maintaining regulatory equivalence.

Physical Differences: The 208-5 exhibits a greater height above board (0.334" versus 0.271"). PCB layout verification is required to confirm adequate clearance in the target application. The 208-5 operates across a wider temperature range (-55°C to 85°C versus -20°C to 70°C), providing enhanced thermal margin.

Contact Material: The DS05 features gold-plated phosphor bronze contacts; the 208-5 uses tin finish. For 24VDC low-current applications, both contact finishes are functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can the CTS 208-5 replace the APEM DS05 in existing designs?

A: Yes. Both parts share identical circuit configuration (SPST), electrical ratings (50mA, 24VDC), number of positions (5), mounting type (through-hole), pitch (0.100"), and termination style (PC pin). Physical height difference requires PCB clearance verification.

Q: What is the primary reason for substitution?

A: The DS05 is obsolete. The 208-5 is an active product with equivalent electrical and mechanical specifications, ensuring design continuity and supply availability.

Q: Does the height difference affect compatibility?

A: The 208-5 is 0.063" (1.60mm) taller than the DS05. Verify that the target PCB layout provides sufficient clearance above the switch actuator. If clearance is constrained, the DS05 footprint may not accommodate the 208-5.

Q: Are the contact finishes interchangeable?

A: Yes, for 24VDC applications. Gold and tin finishes both provide adequate conductivity and corrosion resistance at this voltage level. Contact finish selection does not affect functional substitution.

Q: What is the operating temperature difference?

A: The 208-5 operates from -55°C to 85°C, compared to the DS05 range of -20°C to 70°C. The 208-5 provides wider thermal operating margin and is suitable for applications requiring extended temperature performance.

Q: Are both parts RoHS compliant?

A: Yes. Both the DS05 and 208-5 are ROHS3 compliant and REACH unaffected, maintaining regulatory equivalence for EU and global markets.

Q: What packaging is available?

A: The DS05 is supplied in standard packaging. The 208-5 is supplied in tube packaging, which may affect handling and assembly processes depending on production equipment compatibility.
