DSR06T DIP Switch SPST 6 Position Equivalent & Substitute Parts

Part Overview

The DSR06T is a slide-actuated DIP switch manufactured by APEM Inc., configured as a single-pole single-throw (SPST) switch with 6 positions. This component is rated for 50mA at 24VDC and features through-hole mounting with PC pin termination. The DSR06T is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. Suitable alternatives must maintain functional compatibility across circuit configuration, electrical ratings, and mechanical form factor.

Key Parameters

Number of Positions	6
Current Rating	50mA
Voltage Rating	24VDC
Actuator Type	Slide (Standard)
Mounting Type	Through Hole
Pitch	0.100" (2.54mm)

Substitute Part Grouping Explanation

Substitution eligibility for the DSR06T is determined by the following mandatory parameters:

Circuit Configuration: Must be SPST
Number of Positions: Must be 6
Mounting Type: Must be Through Hole
Pitch: Must be 0.100" (2.54mm)
Termination Style: Must be PC Pin
Actuator Type: Must be Slide (Standard)

The substitute parts 206-6LPST and 208-6LPST (both CTS Electrocomponents) meet all mandatory substitution criteria. The 78RB06ST (Grayhill Inc.) also satisfies these core requirements but operates at higher electrical ratings (150mA, 30VDC) compared to the DSR06T specification.

Engineering Selection Recommendations

206-6LPST (CTS Electrocomponents): This part is the closest functional equivalent to the DSR06T. It maintains identical electrical ratings (50mA, 24VDC), circuit configuration, and mechanical form factor. The 206-6LPST is in active production status with ROHS3 compliance. The extended operating temperature range (-55°C ~ 85°C) and higher electrical life rating (10,000 cycles) provide improved performance margins. Gold contact finish matches the original specification. Height above board is 0.299" compared to 0.222" for the DSR06T; verify PCB clearance in space-constrained layouts.

208-6LPST (CTS Electrocomponents): This alternative maintains the same electrical ratings and mechanical compatibility as the 206-6LPST. The primary distinction is tin contact finish instead of gold. Electrical life rating matches the DSR06T at 2,000 cycles. Select this part only if tin contact finish is acceptable for the application and gold plating is not required.

78RB06ST (Grayhill Inc.): This part exceeds the DSR06T electrical specifications with 150mA current rating and 30VDC voltage rating. It is suitable for applications requiring higher electrical capacity while maintaining the same 6-position SPST configuration and through-hole mounting. The 78RB06ST features gold contact finish and operates across -40°C ~ 85°C. Height above board is 0.265", intermediate between the DSR06T and CTS alternatives. All parts carry ROHS3 compliance and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can the 206-6LPST or 208-6LPST be used as direct replacements for the DSR06T?

A: Yes. Both CTS parts maintain identical circuit configuration (SPST), position count (6), current rating (50mA), voltage rating (24VDC), pitch (0.100"), and through-hole PC pin termination. Verify PCB layout accommodates the increased height above board (0.299" vs. 0.222").

Q: What is the difference between 206-6LPST and 208-6LPST?

A: The primary difference is contact finish: 206-6LPST uses gold finish, while 208-6LPST uses tin finish. Both maintain identical electrical ratings and mechanical specifications. The 206-6LPST offers higher electrical life (10,000 cycles vs. 2,000 cycles).

Q: Is the 78RB06ST compatible with DSR06T applications?

A: The 78RB06ST is mechanically and functionally compatible but operates at higher electrical ratings (150mA, 30VDC). It is suitable for applications where the DSR06T is specified, provided the higher ratings do not create design conflicts. Verify that the increased height above board (0.265") does not interfere with PCB layout.

Q: Are all substitute parts RoHS compliant?

A: Yes. The DSR06T and all listed substitute parts (206-6LPST, 208-6LPST, 78RB06ST) are ROHS3 compliant and REACH unaffected.

Q: What packaging is available for substitute parts?

A: The 206-6LPST and 208-6LPST are supplied in tube packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Does the DSR06T have any active alternatives from APEM Inc.?

A: The DSR06T is obsolete. No active APEM alternatives are listed. The CTS Electrocomponents 206-6LPST and 208-6LPST are the recommended active-production substitutes.
