GDS02S Equivalent & Substitute Parts

Part Overview

The GDS02S is a surface mount DIP slide switch manufactured by TE Connectivity ALCOSWITCH Switches. This SPST (Single Pole Single Throw) component is rated for 25mA at 24VDC and features a standard slide actuator with flush, recessed positioning. The GDS02S is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support, maintenance, and production continuity. Substitute parts must maintain electrical and mechanical compatibility while meeting current manufacturing and compliance standards.

Substitute Part Grouping Explanation

Substitution of the GDS02S is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Electrical Parameters:

Circuit configuration (SPST)
Number of positions (2)
Current rating (25mA)
Voltage rating (24VDC)
Contact material and finish (Copper Alloy, Gold)

Mechanical Parameters:

Actuator type and level (Slide Standard, Flush Recessed)
Mounting type (Surface Mount)
Termination style (Gull Wing)
Pitch (0.100" / 2.54mm)
Height above board (0.114" / 2.90mm)
Body material (Polyphenylene Sulfide)
Length (0.194" / 4.93mm)

Environmental & Operational Parameters:

Operating temperature range (-30°C to 85°C)
Mechanical life (1,000 Cycles)
Electrical life (1,000 Cycles)
Washable capability (Yes)
Tape Seal feature

The substitute part 1825006-3 meets all these criteria and is therefore a direct functional equivalent.
