Grayhill 97C06S DIP Switch - Equivalent & Substitute Parts

Part Overview

The Grayhill 97C06S is a 6-position surface mount DIP switch with SPST circuit configuration, rated for 25mA at 24VDC. This component features a slide actuator with flush, recessed level and gold-plated copper alloy contacts. The 97C06S is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Grayhill 97C06S is determined by strict equivalence across the following critical parameters:

Electrical Compatibility:

• Circuit type: SPST
• Number of positions: 6
• Current rating: 25mA minimum
• Voltage rating: 24VDC minimum

Mechanical Compatibility:

• Mounting type: Surface Mount
• Termination style: Gull Wing
• Pitch: 0.050" (1.27mm), Half
• Actuator type: Slide (Standard)
• Actuator level: Flush, Recessed

Environmental Compatibility:

• Operating temperature range must encompass or exceed -40°C ~ 85°C
• Washable construction required

The CTS Electrocomponents 218-6LPST meets all substitution criteria across these parameters.

Parameter Comparison

Engineering Selection Recommendations

The CTS Electrocomponents 218-6LPST is a functional equivalent to the obsolete Grayhill 97C06S across all critical electrical and mechanical parameters. Both components share identical circuit configuration (SPST), position count (6), current rating (25mA), voltage rating (24VDC), actuator type (slide standard), mounting method (surface mount), and termination style (gull wing).

Compliance Advantage: The CTS 218-6LPST holds ROHS3 compliance status, whereas the Grayhill 97C06S is RoHS non-compliant. For applications subject to RoHS regulations, the CTS substitute provides regulatory alignment.

Temperature Performance: The CTS 218-6LPST operates across -55°C ~ 85°C, exceeding the Grayhill specification of -40°C ~ 85°C. This extended lower temperature range provides additional operational margin.

Physical Dimensions: Height above board differs by 0.041" (1.05mm), with the CTS component measuring 0.104" versus the Grayhill at 0.063". Length dimensions are negligibly different (0.002" variance). PCB layout and clearance verification is required for applications with height-constrained designs.

Contact Material Difference: The Grayhill uses copper alloy contacts while the CTS uses beryllium copper. Both are gold-plated and rated for identical electrical parameters. Beryllium copper provides superior spring characteristics and contact reliability.

Active Production Status: The CTS 218-6LPST is in active production with 11,964 pieces in stock, ensuring long-term availability compared to the obsolete Grayhill part.

Frequently Asked Questions (FAQ)

Q: Can the CTS 218-6LPST directly replace the Grayhill 97C06S in existing designs?

A: The CTS 218-6LPST is electrically and functionally equivalent across all critical parameters. However, the 0.041" height difference requires verification that PCB clearance and component placement constraints are satisfied. Mechanical fit testing is recommended before production implementation.

Q: What are the key differences between these two DIP switches?

A: Primary differences are: (1) Product status—CTS is active production versus Grayhill obsolete; (2) RoHS compliance—CTS is ROHS3 compliant; (3) Operating temperature range—CTS extends to -55°C; (4) Contact material—CTS uses beryllium copper versus Grayhill copper alloy; (5) Height above board—CTS is 0.041" taller. All electrical ratings and circuit configurations are identical.

Q: Are there any compatibility concerns with PCB assembly?

A: The increased height of the CTS component (0.104" versus 0.063") may affect clearance in designs with tight vertical constraints. Pitch, termination style, and footprint are identical, so standard gull wing solder processes apply. Verify clearance to adjacent components and conformal coating requirements.

Q: Does the beryllium copper contact material affect performance?

A: Beryllium copper provides superior spring force retention and contact reliability compared to copper alloy. Both materials are gold-plated and rated for identical electrical parameters (25mA, 24VDC). The CTS material selection represents an engineering improvement.

Q: What is the inventory status for the CTS substitute?

A: The CTS Electrocomponents 218-6LPST has 11,964 pieces in new original stock, providing immediate availability and long-term supply security compared to the obsolete Grayhill part.

Q: Are there any regulatory or compliance differences?

A: The CTS 218-6LPST is ROHS3 compliant, while the Grayhill 97C06S is RoHS non-compliant. Both components are REACH Unaffected and classified as EAR99 for export control purposes. For applications subject to RoHS directives, the CTS substitute provides regulatory compliance.

Q: What packaging is available for the CTS substitute?

A: The CTS 218-6LPST is supplied in tube packaging, suitable for automated pick-and-place assembly and manual component handling.
