Grayhill 76RSB09SLT DIP Switch Rocker SPST Equivalent & Substitute Parts

Part Overview

The Grayhill 76RSB09SLT is a 9-position DIP switch with rocker actuator, rated for 150mA at 30VDC, designed for through-hole PCB mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing production support, design updates, and inventory management. The substitute part 76RSB10SLT from the same manufacturer series provides electrical and mechanical compatibility with documented parameter differences that must be evaluated for specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76RSB09SLT is determined by strict equivalence across the following critical parameters:

Critical Parameters (Must Match Exactly):

• Circuit configuration: SPST (Single Pole Single Throw)
• Current rating: 150mA
• Voltage rating: 30VDC
• Actuator type: Rocker
• Mounting type: Through Hole
• Pitch: 0.100 inches (2.54mm)

Important Parameters (Must Be Compatible):

• Height above board: 0.292 inches (7.41mm)
• Operating temperature range: -40°C to 85°C
• Contact material: Copper Alloy
• Contact finish: Gold
• Mechanical and electrical life: 2,000 cycles minimum

The substitute part 76RSB10SLT differs from the main part in the number of positions (10 versus 9) and physical length (1.080 inches versus 0.980 inches). All other electrical, mechanical, and environmental parameters remain identical. This difference in position count and length must be evaluated against specific PCB layout constraints and application requirements.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The 76RSB10SLT is electrically and mechanically compatible with the 76RSB09SLT for applications where the 10-position configuration and increased physical length (0.100 inches additional) do not create design constraints. Both components share identical electrical ratings, contact materials, operating temperature ranges, and lifecycle specifications.

Product Status Consideration:

The 76RSB09SLT is classified as obsolete, while the 76RSB10SLT maintains active product status. This status difference indicates ongoing manufacturing support, availability, and compliance updates for the 76RSB10SLT. The 76RSB10SLT meets ROHS3 compliance, representing a more current regulatory standard than the RoHS Compliant designation of the main part.

Design Integration Requirements:

Selection of the 76RSB10SLT requires verification that:

• PCB layout accommodates the additional 0.100-inch length (27.43mm total versus 24.89mm)
• Application logic supports 10-position configuration instead of 9-position
• Mechanical clearance above the board remains acceptable at 0.292 inches height

Compliance and Regulatory Status:

Both components maintain identical REACH unaffected status, EAR99 export classification, and HTSUS coding. The 76RSB10SLT provides enhanced regulatory alignment through ROHS3 compliance for new designs and production transitions.

Frequently Asked Questions (FAQ)

Q: Can the 76RSB10SLT directly replace the 76RSB09SLT in existing designs?

A: Electrical and mechanical compatibility exists for direct substitution provided that PCB layout accommodates the additional 0.100-inch length and the application supports 10-position configuration instead of 9-position. Height above board remains identical at 0.292 inches, and all electrical parameters (150mA, 30VDC, SPST) are equivalent.

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

A: The 76RSB10SLT provides 10 switch positions with a total length of 1.080 inches, compared to the 9-position 76RSB09SLT with a length of 0.980 inches. All other specifications, including current rating, voltage rating, actuator type, pitch, and operating temperature range, are identical.

Q: Why is the 76RSB09SLT listed as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued active production and support for this part number. The 76RSB10SLT, with active product status, represents the current manufacturing alternative within the same series.

Q: Are there any compliance differences between these parts?

A: Both components maintain REACH unaffected status and EAR99 export classification. The 76RSB10SLT carries ROHS3 compliance, while the 76RSB09SLT carries RoHS compliance. Both designations indicate compliance with hazardous substance restrictions.

Q: What packaging differences exist between these parts?

A: The 76RSB09SLT is supplied with standard packaging (dash notation), while the 76RSB10SLT is supplied in tube packaging. This difference affects handling, storage, and automated assembly considerations.

Q: Are the contact materials and finishes identical?

A: Yes. Both parts feature copper alloy contact material with gold finish, ensuring equivalent electrical performance and corrosion resistance across the operating temperature range of -40°C to 85°C.

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

A: Both the 76RSB09SLT and 76RSB10SLT are rated for 2,000 mechanical cycles and 2,000 electrical cycles, indicating identical durability and lifecycle performance.

Q: Can these parts be used in washable applications?

A: Yes. Both components are rated as washable, supporting cleaning processes in manufacturing environments.

Q: What is the pitch specification, and is it identical between parts?

A: Both parts feature a 0.100-inch (2.54mm) pitch, which is the standard spacing between switch positions. This identical pitch ensures compatibility with standard DIP switch footprints on PCBs.
