Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 206-5ST are identified based on the following critical parameters that determine functional compatibility:

Core Compatibility Criteria:

• Circuit configuration: SPST (maintained across all substitutes)
• Number of positions: 5 (maintained across all substitutes)
• Mounting type: Through hole (maintained across all substitutes)
• Pitch: 0.100" (2.54mm) (maintained across all substitutes)
• Termination style: PC pin (maintained across all substitutes)
• Contact finish: Gold (maintained across all substitutes)
• Washable design: Yes (maintained across all substitutes)

Allowable Parameter Variations:

• Current rating: Substitutes rated at 150mA exceed the 50mA requirement and are acceptable for applications within their rating
• Voltage rating: Substitutes rated at 30VDC exceed the 24VDC requirement and are acceptable for applications within their rating
• Actuator type: Slide actuator (206-5ST) and rocker actuator (76SB05ST) represent different mechanical interfaces; slide-to-slide substitution (78B05ST) maintains identical actuator type
• Operating temperature: Substitutes with -40°C to 85°C range are acceptable where the extended lower temperature limit of the main part (-55°C) is not required
• Electrical life: Substitutes with 2,000 cycles are acceptable where the 10,000-cycle rating of the main part is not required

Parameter Comparison

Engineering Selection Recommendations

206-5ST (CTS Electrocomponents) - Primary Part Select this part when the extended operating temperature range (-55°C to 85°C) and higher electrical life rating (10,000 cycles) are required. This part is active in production with established supply availability.

78B05ST (Grayhill Inc.) - Preferred Substitute This part is the closest functional equivalent to the 206-5ST. It maintains identical actuator type (slide), circuit configuration, position count, and pitch. The 78B05ST provides higher current and voltage ratings (150mA at 30VDC) and is suitable for applications where the extended temperature range and 10,000-cycle rating of the main part are not required. Both parts are ROHS3 compliant and REACH unaffected.

76SB05ST (Grayhill Inc.) - Alternative Substitute This part shares the same circuit configuration, position count, and pitch as the 206-5ST but features a rocker actuator instead of a slide actuator. The rocker actuator represents a different mechanical interface and may require PCB layout or mechanical housing adjustments. Select this part only when rocker actuation is acceptable or preferred for the application. Like the 78B05ST, it provides higher current and voltage ratings and is suitable where extended temperature and cycle life requirements do not apply.

Frequently Asked Questions (FAQ)

Q: Can the 78B05ST directly replace the 206-5ST on the same PCB? A: Yes. The 78B05ST maintains identical pitch (0.100"), termination style (PC pin), and mounting type (through hole). The height above board differs slightly (0.315" versus 0.334"), which is typically acceptable in standard through-hole applications. Verify mechanical clearance in your specific design.

Q: What is the key difference between the 78B05ST and 76SB05ST substitutes? A: The primary difference is actuator type. The 78B05ST uses a slide actuator (matching the 206-5ST), while the 76SB05ST uses a rocker actuator. Both are SPST 5-position switches with identical pitch and termination. Actuator selection depends on user interface requirements and mechanical design constraints.

Q: Are the Grayhill substitutes suitable for applications requiring the full -55°C to 85°C temperature range? A: No. Both Grayhill substitutes (76SB05ST and 78B05ST) are rated for -40°C to 85°C. If your application requires operation below -40°C, the 206-5ST must be used.

Q: Can I use a substitute if my application requires 10,000 electrical cycles? A: No. Both Grayhill substitutes are rated for 2,000 electrical cycles. If your application requires 10,000 cycles, the 206-5ST must be used.

Q: Are all three parts RoHS and REACH compliant? A: Yes. The 206-5ST, 78B05ST, and 76SB05ST are all ROHS3 compliant and REACH unaffected.

Q: What happens if I use a 150mA-rated switch in a 50mA application? A: The higher current rating of the substitute parts (150mA) is acceptable for applications requiring only 50mA. The switch will operate within its design limits. Verify that the 30VDC rating is compatible with your circuit voltage requirements.

Q: Is the slight height difference between parts a concern? A: The 206-5ST has a height of 0.334" (8.48mm), while both Grayhill substitutes measure 0.315" (8.00mm). This 0.019" difference is typically negligible in standard through-hole designs. Verify mechanical clearance with your specific PCB layout and enclosure design.
