DS05T DIP Switch SPST 5 Position 50mA 24VDC Equivalent & Substitute Parts

Part Overview

The DS05T 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 PCB mounting with a 0.100" pitch. The DS05T carries an obsolete product status, making identification of functionally equivalent alternatives essential for ongoing design support, legacy system maintenance, and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS05T is determined by strict alignment with the following core parameters:

• Circuit Configuration: SPST (single-pole single-throw)
• Number of Positions: 5
• Voltage Rating: 24VDC minimum
• Current Rating: 50mA minimum
• Actuator Type: Slide (Standard)
• Mounting Type: Through Hole
• Pitch: 0.100" (2.54mm)
• Contact Finish: Gold
• Termination Style: PC Pin

Substitute parts must meet or exceed all electrical ratings and maintain mechanical compatibility with the specified pitch and mounting footprint. Parts that fall below the current or voltage rating, use different actuator types, or employ incompatible mounting configurations are not considered equivalent.

Parameter Comparison

Engineering Selection Recommendations

206-5ST (CTS Electrocomponents): This part is a direct functional equivalent to the DS05T. It matches the 50mA current rating, 24VDC voltage rating, 5-position SPST configuration, and through-hole mounting with 0.100" pitch. The 206-5ST is currently in active production status and carries ROHS3 compliance. The height above board is 0.063" greater than the DS05T; verify clearance in confined PCB layouts. The extended electrical life rating of 10,000 cycles provides enhanced durability compared to the DS05T specification.

KAS1105E (E-Switch): This part shares the same circuit configuration, position count, voltage rating, actuator type, and mounting footprint as the DS05T. However, the KAS1105E is rated for 25mA maximum current, which is 50% of the DS05T rating. The KAS1105E is suitable only for applications where the circuit current demand does not exceed 25mA. The part is in active production and ROHS3 compliant. Physical dimensions are comparable to the DS05T, with height above board of 0.275" (6.99mm).

Frequently Asked Questions (FAQ)

Q: Can the 206-5ST replace the DS05T in all applications? A: The 206-5ST is electrically and mechanically compatible with the DS05T for applications requiring up to 50mA at 24VDC. Verify PCB layout clearance, as the 206-5ST height above board is 0.334" compared to the DS05T at 0.271". Both parts use identical 0.100" pitch and PC pin termination.

Q: Is the KAS1105E a suitable replacement for the DS05T? A: The KAS1105E is compatible only if the circuit current requirement does not exceed 25mA. If the application requires the full 50mA rating of the DS05T, the KAS1105E will not provide adequate current capacity and must not be used.

Q: What is the primary difference between the substitute parts? A: The 206-5ST maintains the 50mA current rating of the DS05T and is recommended for direct replacement. The KAS1105E has a reduced current rating of 25mA and is suitable only for lower-current applications. Both alternatives are in active production, whereas the DS05T is obsolete.

Q: Are all substitute parts RoHS compliant? A: Yes. The DS05T, 206-5ST, and KAS1105E are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What are the packaging differences? A: The DS05T original packaging is listed as "-" (not specified). Both substitute parts are supplied in tube packaging, which is standard for DIP switch distribution.
