Grayhill 76SB09ST DIP Switch Rocker SPST Equivalent & Substitute Parts

Part Overview

The Grayhill 76SB09ST is a 9-position DIP switch with rocker actuator, rated for 150mA at 30VDC, designed for through-hole mounting applications. This component features gold-plated copper alloy contacts, thermoplastic housing, and operates across the industrial temperature range of -40°C to 85°C.

The 76SB09ST carries an Obsolete product status. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support legacy system maintenance where this component is specified in active applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76SB09ST is determined by the following critical parameters:

Electrical Compatibility Parameters:

• Circuit configuration (SPST)
• Current rating (150mA minimum)
• Voltage rating (30VDC minimum)

Mechanical Compatibility Parameters:

• Actuator type (Rocker)
• Mounting type (Through Hole)
• Termination style (PC Pin)
• Pitch spacing (0.100" / 2.54mm)
• Contact material and finish (Copper Alloy, Gold)

Environmental & Compliance Parameters:

• Operating temperature range (-40°C to 85°C)
• RoHS compliance status
• Mechanical and electrical life rating (2,000 cycles minimum)

The 76SB10ST qualifies as a substitute part because it maintains identical electrical ratings, mechanical mounting characteristics, contact specifications, and environmental operating parameters. The primary difference is the number of switch positions (10 versus 9), which does not affect electrical or mechanical compatibility in applications where the additional position capacity is acceptable or unused.

Engineering Selection Recommendations

For Direct Substitution:

The 76SB10ST is suitable as a substitute for the 76SB09ST in applications where:

1. The PCB layout accommodates the increased length (1.080" versus 0.980"), representing a 0.100" (2.54mm) increase in the longitudinal dimension.
2. The application does not require exactly 9 switch positions; the additional 10th position can remain unused or be configured as needed.
3. Supply chain continuity is prioritized, as the 76SB10ST maintains Active product status with established inventory availability (1,309 pieces in stock versus 897 pieces for the obsolete 76SB09ST).

Compliance Considerations:

Both parts maintain RoHS compliance. The 76SB10ST carries ROHS3 certification, representing current regulatory alignment. Both parts are REACH Unaffected and classified under ECCN EAR99 and HTSUS 8536.50.9065, ensuring consistent export and regulatory treatment.

Packaging Consideration:

The 76SB10ST is supplied in Tube packaging, whereas the 76SB09ST packaging specification was not provided. Verify packaging requirements for your procurement and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 76SB10ST replace the 76SB09ST in my existing design?

A: Yes, provided that your PCB layout accommodates the 0.100" (2.54mm) length increase and your application does not require exactly 9 positions. All electrical and mechanical parameters are identical, including current rating, voltage rating, actuator type, mounting configuration, and contact specifications.

Q: What is the primary difference between these two parts?

A: The 76SB10ST provides 10 switch positions compared to the 76SB09ST's 9 positions. This results in a proportional increase in overall length from 0.980" to 1.080". All other specifications remain identical.

Q: Why is the 76SB09ST listed as Obsolete?

A: The 76SB09ST carries Obsolete product status, indicating that Grayhill Inc. has discontinued active production and support. The 76SB10ST, with Active status, represents the current product line equivalent within the 76 series.

Q: Are there any compliance differences between these parts?

A: Both parts are RoHS compliant. The 76SB10ST carries ROHS3 certification, representing the latest regulatory standard. Both parts are REACH Unaffected and share identical ECCN and HTSUS classifications.

Q: What should I verify before implementing the 76SB10ST as a substitute?

A: Verify that your PCB layout accommodates the increased length dimension (1.080" versus 0.980"). Confirm that your application logic can function with 10 positions or that the additional position will remain unused. Assess packaging requirements, as the 76SB10ST is supplied in Tube format.

Q: Is the 76SB10ST available in the same packaging as the 76SB09ST?

A: The 76SB10ST is supplied in Tube packaging. The original packaging specification for the 76SB09ST was not provided in the technical data. Contact your supplier to confirm packaging compatibility with your assembly requirements.

Q: Do both parts have the same mechanical and electrical life ratings?

A: Yes. Both the 76SB09ST and 76SB10ST are rated for 2,000 mechanical cycles and 2,000 electrical cycles, ensuring equivalent operational durability.

Q: What is the pitch spacing for both parts?

A: Both parts feature a pitch of 0.100" (2.54mm), maintaining identical spacing between switch positions and ensuring compatible PCB footprint design.
