DS02T DIP Switch SPST 24VDC Equivalent & Substitute Parts

Part Overview

The DS02T is a slide-actuated DIP switch manufactured by APEM Inc., configured as a single-pole single-throw (SPST) switch with 2 positions. It is rated for 50mA at 24VDC and features through-hole PC pin termination with 0.100" pitch. The DS02T is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. This reference provides direct electrical and mechanical equivalents based on matching core functional parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DS02T are identified based on matching the following critical parameters:

• Circuit Configuration: SPST (single-pole single-throw)
• Number of Positions: 2
• Voltage Rating: 24VDC
• Actuator Type: Slide (Standard)
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Pitch: 0.100" (2.54mm)
• Contact Finish: Gold

The substitute parts listed below meet these core electrical and mechanical requirements. Variations in current rating, operating temperature range, mechanical life, and electrical life are noted in the parameter comparison table and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

206-2ST (CTS Electrocomponents): This part is the closest electrical equivalent to the DS02T, matching the 50mA current rating and all core mechanical parameters. The 206-2ST is classified as active product status, ensuring ongoing availability. It provides extended electrical life (10,000 cycles versus 2,000 cycles) and a wider operating temperature range (-55°C ~ 85°C). The height above board is 0.063" greater than the DS02T, which must be verified against PCB layout constraints. This part is suitable for applications requiring the full 50mA current capacity.

KAS1102E (E-Switch): This part matches all core mechanical and electrical parameters except current rating, which is rated at 25mA versus the DS02T's 50mA. The KAS1102E is classified as active product status. It provides comparable operating temperature range (-40°C ~ 85°C) and identical electrical life (2,000 cycles). The height above board (0.275") is closer to the DS02T specification. This part is suitable only for applications where the circuit current requirement does not exceed 25mA.

Both substitute parts are ROHS3 compliant and carry EAR99 ECCN classification, matching the regulatory status of the DS02T.

Frequently Asked Questions (FAQ)

Q: Can the KAS1102E be used in place of the DS02T in all applications?

A: The KAS1102E is electrically compatible only for applications where circuit current does not exceed 25mA. The DS02T is rated for 50mA; using the KAS1102E in a 50mA circuit will exceed its current rating and may result in contact degradation or failure.

Q: What is the primary difference between the 206-2ST and DS02T?

A: The 206-2ST matches the DS02T in current rating (50mA) and all core mechanical parameters. The primary differences are extended electrical life (10,000 cycles versus 2,000 cycles), wider operating temperature range (-55°C ~ 85°C versus -20°C ~ 70°C), and slightly greater height above board (0.334" versus 0.271"). These differences must be evaluated against specific application requirements.

Q: Are all three parts pin-compatible?

A: All three parts feature 0.100" (2.54mm) pitch PC pin termination through-hole mounting. However, the height above board varies: DS02T at 0.271", 206-2ST at 0.334", and KAS1102E at 0.275". PCB layout and clearance requirements must be verified before substitution.

Q: Do all substitute parts meet the same regulatory requirements as the DS02T?

A: Yes. Both the 206-2ST and KAS1102E are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification, matching the regulatory status of the DS02T.

Q: Why is the DS02T classified as obsolete?

A: The DS02T is no longer in active production. The 206-2ST and KAS1102E represent current active alternatives that meet equivalent functional requirements for new designs and production continuity.
