Grayhill 76SB09S DIP Switch - Equivalent & Substitute Parts

Part Overview

The Grayhill 76SB09S is a 9-position DIP switch with rocker actuator, rated for 150mA at 30VDC, designed for through-hole mounting in industrial and commercial control applications. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, maintenance, and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Grayhill 76SB09S is determined by the following critical parameters that must be maintained or exceeded:

Mandatory Compatibility Parameters:

• Circuit configuration: SPST
• Number of positions: 9
• Mounting type: Through hole
• Pitch: 0.100" (2.54mm)
• Termination style: PC Pin
• Contact finish: Gold

Performance Parameters (Minimum Requirements):

• Current rating: Must support 150mA minimum
• Voltage rating: Must support 30VDC minimum
• Operating temperature range: Must encompass -40°C to +85°C

The CTS Electrocomponents 206-9ST meets the mandatory compatibility parameters. However, the current rating (50mA) and voltage rating (24VDC) are below the original specification, indicating this substitute is suitable only for applications where the actual operating conditions do not exceed the 206-9ST ratings.

Engineering Selection Recommendations

For Direct Replacement in Existing Systems:

The CTS Electrocomponents 206-9ST provides functional substitution for the obsolete Grayhill 76SB09S with the following considerations:

1. Electrical Derating: The 206-9ST operates at reduced current (50mA vs. 150mA) and voltage (24VDC vs. 30VDC) ratings. This substitute is suitable only when actual circuit operating conditions remain within the 206-9ST specifications.

2. Actuator Difference: The 206-9ST uses a slide actuator instead of the rocker actuator on the original part. This affects user interface and may require panel redesign if the rocker actuation is functionally required.

3. Compliance Advantage: The 206-9ST is ROHS3 compliant and carries active product status, providing long-term availability and regulatory alignment for new designs or system upgrades.

4. Mechanical Life: The 206-9ST demonstrates superior electrical life (10,000 cycles vs. 2,000 cycles), providing extended operational durability.

5. Temperature Range: The 206-9ST supports an extended lower temperature limit (-55°C vs. -40°C), suitable for wider environmental applications.

For New Designs: Use the CTS 206-9ST only if application requirements do not exceed 50mA at 24VDC. For applications requiring the full 150mA at 30VDC specification, alternative suppliers must be evaluated.

Frequently Asked Questions (FAQ)

Q: Can the CTS 206-9ST directly replace the Grayhill 76SB09S in all applications?

A: No. While both are 9-position SPST DIP switches with identical pitch and through-hole mounting, the 206-9ST has lower electrical ratings (50mA at 24VDC vs. 150mA at 30VDC). Substitution is valid only when actual operating conditions remain within the 206-9ST specifications.

Q: What is the significance of the actuator type difference (rocker vs. slide)?

A: The actuator type affects the physical interface and user interaction. The rocker actuator on the 76SB09S provides a different tactile and visual feedback compared to the slide actuator on the 206-9ST. Panel cutouts and user documentation may require modification.

Q: Is the 206-9ST suitable for new product designs?

A: The 206-9ST is suitable for new designs where the application requirements do not exceed 50mA at 24VDC. The part carries active product status and ROHS3 compliance, supporting long-term availability and regulatory requirements.

Q: What is the impact of the height difference (0.315" vs. 0.334")?

A: The 0.019" (0.48mm) height difference is minimal and typically does not affect PCB layout or enclosure clearance in most applications. Verify clearance in space-constrained designs.

Q: Why is the 76SB09S obsolete?

A: The Grayhill 76SB09S is classified as obsolete, indicating discontinued manufacturing. The CTS 206-9ST represents an active alternative from a different manufacturer with comparable functionality and improved compliance status.

Q: Are there any packaging differences?

A: The 76SB09S is supplied in standard packaging, while the 206-9ST is supplied in tube packaging. This affects handling and storage but does not impact electrical or mechanical performance.
