Grayhill 76SB09T DIP Switch Rocker SPST Equivalent & Substitute Parts

Part Overview

The Grayhill 76SB09T is a 9-position DIP switch with rocker actuator, rated for 150mA at 30VDC, designed for through-hole mounting in electronic control and configuration applications. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing production support, maintenance, and design continuity. The 76SB09T remains available in inventory (912 pcs), but substitute parts with active product status provide long-term supply assurance and manufacturing flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76SB09T is determined by strict alignment with the following core parameters:

Mandatory Matching Parameters:

• Circuit configuration (SPST)
• Mounting type (Through Hole)
• Pitch spacing (0.100" / 2.54mm)
• Actuator type and level (Rocker, Raised)
• Contact material and finish (Copper Alloy, Gold)
• Operating temperature range (-40°C to 85°C)
• Mechanical and electrical life rating (2,000 Cycles minimum)
• RoHS compliance status

Allowable Variation Parameters:

• Number of positions (9 vs. 10)
• Physical length (varies with position count)
• Product status (Obsolete to Active)
• Packaging format (bulk to tube)
• Inventory availability

The 76SB10T qualifies as a direct substitute because it maintains all mandatory parameters while differing only in position count (10 vs. 9) and resulting physical length. This variation does not affect electrical performance, switching characteristics, or PCB mounting compatibility when the additional position is not utilized in the application circuit.

Engineering Selection Recommendations

Primary Recommendation: 76SB10T

The Grayhill 76SB10T is the qualified substitute for the 76SB09T based on the following engineering criteria:

1. Regulatory Compliance: The 76SB10T maintains RoHS compliance with ROHS3 status, representing current regulatory alignment. Both parts are REACH Unaffected, ensuring no supply chain restrictions.

2. Product Status Advantage: The 76SB10T holds Active product status, providing assured long-term availability and manufacturing support. The 76SB09T is classified as Obsolete, creating supply risk for future production runs and maintenance applications.

3. Electrical & Mechanical Equivalence: All critical electrical parameters (150mA, 30VDC, SPST configuration) and mechanical specifications (rocker actuator, through-hole mounting, 2.54mm pitch, 2,000-cycle life) are identical between the two parts.

4. Physical Compatibility: The 76SB10T length increase of 0.100" (2.54mm) results from the additional switch position. This dimension change does not affect PCB footprint compatibility when the component is mounted in a standard through-hole configuration. The identical pitch spacing and height above board ensure mechanical interchangeability.

5. Functional Compatibility: Applications utilizing only 9 of the 10 available positions in the 76SB10T operate identically to the 76SB09T. The additional position remains unused and does not impact circuit behavior, switching performance, or electrical characteristics.

Selection Criteria Summary:

• Use 76SB10T for new designs and production continuity
• Use 76SB09T only when existing inventory is available and 9-position configuration is specifically required
• Both parts are suitable for applications requiring SPST DIP switches rated 150mA at 30VDC with rocker actuation in through-hole mounting

Frequently Asked Questions (FAQ)

Q: Can the 76SB10T directly replace the 76SB09T in existing PCB designs?

A: Yes. The 76SB10T is mechanically and electrically compatible with the 76SB09T. Both components share identical pitch spacing (0.100" / 2.54mm), height above board (0.315" / 8.00mm), and through-hole termination. The 76SB10T is 0.100" longer due to the additional switch position, but this does not affect PCB footprint compatibility or mounting hole alignment.

Q: What is the functional difference between the 76SB09T and 76SB10T?

A: The primary difference is the number of available switch positions: 9 positions versus 10 positions. Both parts are SPST (Single Pole Single Throw) switches with identical electrical ratings (150mA, 30VDC) and mechanical characteristics. Applications using only 9 positions will function identically with either part.

Q: Why is the 76SB09T classified as Obsolete?

A: Obsolete status indicates that Grayhill Inc. has discontinued active manufacturing and support for this part number. The 76SB10T, with Active product status, represents the current production equivalent and ensures ongoing availability for future orders and supply chain continuity.

Q: Are there any compliance differences between the 76SB09T and 76SB10T?

A: Both parts are RoHS Compliant and REACH Unaffected. The 76SB10T carries ROHS3 certification, representing alignment with the most current RoHS directive requirements. Both parts meet the same environmental and regulatory standards for electronic component manufacturing.

Q: What packaging formats are available for these parts?

A: The 76SB09T is available in bulk packaging. The 76SB10T is supplied in Tube packaging. Packaging format does not affect component functionality or electrical performance; it relates only to order quantity, handling, and storage considerations.

Q: Can I use the 76SB10T if my application requires exactly 9 positions?

A: Yes. The 76SB10T contains 10 positions, but applications requiring only 9 positions will operate correctly. The unused 10th position does not affect circuit operation, switching performance, or electrical characteristics. The component functions identically to the 76SB09T when only 9 positions are utilized in the application circuit.

Q: What is the mechanical life rating for both parts?

A: Both the 76SB09T and 76SB10T are rated for 2,000 mechanical cycles and 2,000 electrical cycles. This specification defines the expected operational lifespan under normal switching conditions and is identical for both components.

Q: Are the contact materials the same in both parts?

A: Yes. Both the 76SB09T and 76SB10T use Copper Alloy contacts with Gold finish. This contact material specification ensures consistent electrical reliability, low contact resistance, and corrosion resistance across both part numbers.
