Grayhill 76SB09 DIP Switch - Equivalent & Substitute Parts

Part Overview

The Grayhill 76SB09 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 and new design implementations. The rocker actuator design and electrical specifications define the primary selection criteria for suitable substitutes.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Grayhill 76SB09 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

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

Electrical Performance Parameters:

• 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 Parameters:

• Height above board and overall length must be compatible with existing PCB layouts
• Actuator type may vary (rocker, slide, or equivalent) provided mechanical clearance is verified

The CTS Electrocomponents 206-9 is identified as a substitute part. However, this substitution involves trade-offs in electrical performance that must be evaluated against application requirements.

Engineering Selection Recommendations

Grayhill 76SB09 Continued Use: The 76SB09 remains suitable for applications where existing inventory is available and environmental compliance is not a regulatory requirement. The component's obsolete status and RoHS non-compliance status limit its use in new designs subject to environmental regulations.

CTS Electrocomponents 206-9 Substitution: The 206-9 is electrically and mechanically compatible with the 76SB09 for applications where the following conditions are met:

1. Current Requirement: Application current draw does not exceed 50mA. If the application requires the full 150mA rating of the 76SB09, the 206-9 is not suitable.

2. Voltage Requirement: Application operating voltage does not exceed 24VDC. If the application requires the full 30VDC rating of the 76SB09, the 206-9 is not suitable.

3. Mechanical Fit: The slide actuator of the 206-9 differs from the rocker actuator of the 76SB09. PCB layout and user interface requirements must accommodate this change. The 206-9 is 0.019" (0.48mm) taller; verify clearance above the PCB.

4. Compliance Requirements: The 206-9 is RoHS3 compliant and actively manufactured, making it suitable for new designs and applications subject to environmental regulations.

5. Reliability: The 206-9 offers superior electrical life (10,000 cycles versus 2,000 cycles), providing extended operational durability.

Frequently Asked Questions (FAQ)

Q: Can the CTS 206-9 directly replace the Grayhill 76SB09 in all applications?

A: No. The 206-9 has lower current (50mA vs. 150mA) and voltage (24VDC vs. 30VDC) ratings. Substitution is valid only when application requirements fall within the 206-9 specifications. Additionally, the actuator type differs (slide vs. rocker), requiring mechanical verification.

Q: What is the primary reason the Grayhill 76SB09 is obsolete?

A: The component is classified as obsolete by the manufacturer. The CTS 206-9 represents an active alternative that meets equivalent functional requirements for compatible applications.

Q: Does the height difference between the two parts affect PCB compatibility?

A: The CTS 206-9 is 0.019" (0.48mm) taller than the 76SB09. Verify that the PCB layout and enclosure design provide sufficient clearance above the switch. If clearance is limited, the height difference may prevent substitution.

Q: Are there electrical performance trade-offs with the CTS 206-9?

A: Yes. The 206-9 is rated for 50mA at 24VDC, compared to the 76SB09's 150mA at 30VDC. Applications requiring higher current or voltage must use the original part or identify an alternative with higher ratings. The 206-9 offers superior electrical life (10,000 cycles vs. 2,000 cycles).

Q: What is the impact of the different actuator types?

A: The 76SB09 uses a rocker actuator; the 206-9 uses a slide actuator. These require different user interface designs and PCB layouts. Verify that the slide actuator is mechanically compatible with the intended application before substitution.

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

A: Yes, provided the electrical and mechanical requirements are met. The 206-9 is actively manufactured and RoHS3 compliant, making it suitable for new designs subject to environmental regulations. The 76SB09, being obsolete and RoHS non-compliant, is not recommended for new designs.

Q: What packaging is available for the CTS 206-9?

A: The 206-9 is supplied in tube packaging. Verify that this packaging format is compatible with assembly and inventory management processes.
