Grayhill 76SB08S DIP Switch Equivalent & Substitute Parts

Part Overview

The Grayhill 76SB08S is an 8-position DIP switch with rocker actuator, rated for 150mA at 30VDC, designed for through-hole PCB mounting applications. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance requirements. The part features a raised rocker actuator, gold-plated copper alloy contacts, and operates across the industrial temperature range of -40°C to 85°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76SB08S is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration: SPST
• Number of positions: 8
• Mounting type: Through hole
• Pitch: 0.100" (2.54mm)
• Termination style: PC Pin
• Contact finish: Gold

Electrical Performance Criteria:

• Current rating must equal or exceed 150mA
• Voltage rating must equal or exceed 30VDC
• Operating temperature range must encompass -40°C to 85°C

Mechanical Criteria:

• Actuator level: Raised
• Height above board compatibility with PCB layout

Two substitute parts meet the specified criteria with varying degrees of parameter alignment. The 76SB08ST from Grayhill Inc. provides direct electrical and mechanical equivalence with improved product status. The 206-8ST from CTS Electrocomponents offers functional substitution with parameter deviations that require engineering evaluation.

Engineering Selection Recommendations

76SB08ST (Grayhill Inc.) - Primary Substitute

The 76SB08ST is the direct functional equivalent of the 76SB08S. This part maintains identical electrical ratings (150mA at 30VDC), mechanical dimensions, and actuator configuration. The primary advantage is active product status, ensuring long-term availability and supply chain continuity. The 76SB08ST achieves ROHS3 compliance, addressing regulatory requirements that the obsolete 76SB08S does not meet. Packaging differs (tube versus tape seal), but this does not affect electrical or mechanical performance. This substitute is suitable for direct replacement in new designs and production restocking.

206-8ST (CTS Electrocomponents) - Conditional Substitute

The 206-8ST provides functional substitution with electrical parameter deviations. The current rating of 50mA is below the 150mA specification of the main part, and the voltage rating of 24VDC is below the 30VDC requirement. The actuator type differs (slide versus rocker), affecting user interface and PCB layout compatibility. The height above board is 0.334" compared to 0.315", requiring PCB clearance verification. The 206-8ST offers extended electrical life (10,000 cycles versus 2,000 cycles) and expanded operating temperature range (-55°C to 85°C). This part is suitable only for applications where current and voltage requirements do not exceed 50mA and 24VDC respectively, and where slide actuator operation is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the 76SB08ST directly replace the 76SB08S without PCB modifications?

A: Yes. The 76SB08ST maintains identical electrical ratings, mechanical dimensions, pitch, and height above board. No PCB layout changes are required. Packaging format differs (tube versus tape seal), but this affects only component handling and does not impact electrical or mechanical performance.

Q: What are the key differences between the 76SB08S and 206-8ST?

A: The 206-8ST has reduced current rating (50mA versus 150mA), reduced voltage rating (24VDC versus 30VDC), different actuator type (slide versus rocker), and increased height above board (0.334" versus 0.315"). The 206-8ST is not suitable for applications requiring the full 150mA and 30VDC specifications of the main part.

Q: Is the 76SB08ST suitable for new product designs?

A: Yes. The 76SB08ST is active product status with ROHS3 compliance, making it appropriate for new designs. It provides identical electrical and mechanical performance to the obsolete 76SB08S with improved regulatory compliance and supply availability.

Q: Can the 206-8ST be used in applications rated for 150mA at 30VDC?

A: No. The 206-8ST current rating of 50mA and voltage rating of 24VDC are below the required specifications. Using this part in applications exceeding these ratings will result in component failure and circuit malfunction.

Q: What is the impact of different actuator types (rocker versus slide)?

A: Rocker and slide actuators have different mechanical operation and user interface characteristics. Rocker actuators provide a pivoting motion, while slide actuators move linearly. This affects PCB layout, user interaction, and may require design modifications. The 206-8ST slide actuator is not mechanically interchangeable with the rocker actuator of the 76SB08S without design changes.

Q: Are there packaging considerations when switching from 76SB08S to 76SB08ST?

A: The 76SB08S uses tape seal packaging while the 76SB08ST uses tube packaging. This affects component handling, storage, and automated assembly processes. Verify that assembly equipment and storage procedures are compatible with tube packaging before implementation.

Q: Does the height difference between 76SB08ST and 206-8ST affect PCB compatibility?

A: Yes. The 206-8ST height of 0.334" exceeds the 76SB08S specification of 0.315" by 0.019". This may create clearance conflicts with adjacent components or enclosure constraints. PCB layout must be verified before substitution.
