DS12T DIP Switch SPST 12 Position Equivalent & Substitute Parts

Part Overview

The DS12T is a 12-position DIP switch manufactured by APEM Inc., configured as a single-pole single-throw (SPST) switch with a slide actuator rated for 50mA at 24VDC. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. The DS12T features through-hole mounting with PC pin termination, phosphor bronze contacts with gold finish, and is sealed with epoxy terminals for environmental protection.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS12T is determined by strict alignment with the following core electrical and mechanical parameters:

• Circuit Configuration: Must be SPST
• Number of Positions: Must be 12
• Voltage Rating: Must be 24VDC
• Actuator Type: Must be Slide (Standard)
• Mounting Type: Must be Through Hole
• Termination Style: Must be PC Pin
• Pitch: Must be 0.100" (2.54mm)

The identified substitute parts meet these mandatory criteria. Variations in current rating, operating temperature range, mechanical life, and electrical life are permissible within the constraints of the application circuit design.

Engineering Selection Recommendations

206-12ST (CTS Electrocomponents): This substitute maintains electrical and mechanical parity with the DS12T across all critical parameters. The 206-12ST is an active product with extended electrical life (10,000 cycles versus 2,000 cycles) and broader operating temperature range (-55°C ~ 85°C). It is ROHS3 compliant and suitable for direct replacement in applications where the DS12T is no longer available.

KAS1112E (E-Switch): This substitute meets all mandatory substitution criteria with the exception of current rating, which is rated at 25mA compared to the DS12T's 50mA specification. The KAS1112E is an active product with ROHS3 compliance and identical pitch, mounting type, and termination style. Selection of this part requires circuit-level verification that the 25mA current rating is sufficient for the application.

Frequently Asked Questions (FAQ)

Q: Can the 206-12ST be used as a direct replacement for the DS12T? A: Yes. The 206-12ST maintains identical electrical ratings (50mA, 24VDC), circuit configuration (SPST), position count (12), actuator type (slide standard), mounting type (through hole), and pitch (0.100"). The 206-12ST is an active product with enhanced electrical life specifications.

Q: What is the primary limitation of the KAS1112E as a substitute? A: The KAS1112E is rated for 25mA maximum current, compared to the DS12T's 50mA rating. Applications requiring the full 50mA capacity must use the 206-12ST or verify that circuit current draw does not exceed 25mA.

Q: Are all substitute parts RoHS compliant? A: Yes. Both the 206-12ST and KAS1112E are ROHS3 compliant, matching the DS12T's compliance status.

Q: Do the substitute parts have the same physical footprint? A: All substitute parts share identical pitch (0.100" / 2.54mm) and through-hole PC pin termination. Height above board varies slightly: DS12T (6.88mm), 206-12ST (8.48mm), and KAS1112E (6.99mm). PCB layout compatibility should be verified for height-constrained applications.

Q: What is the difference in operating temperature range? A: The DS12T operates from -20°C to 70°C. The 206-12ST extends this to -55°C to 85°C, and the KAS1112E to -40°C to 85°C. Applications requiring operation outside the DS12T's original range benefit from the broader specifications of the substitute parts.
