Grayhill 97R06T DIP Switch - Equivalent & Substitute Parts

Part Overview

The Grayhill 97R06T is a 6-position surface mount DIP switch with SPST (Single Pole Single Throw) circuit configuration, rated for 25mA at 24VDC. This component is designed for applications requiring discrete switching logic in compact form factors. The part is currently Active in production status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the same application space. The 97R06T has one qualified substitute based on matching core electrical parameters and surface mount compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 97R06T is determined by strict equivalence across the following mandatory parameters:

Electrical Equivalence Requirements:

• Circuit type: SPST (6-position configuration)
• Current rating: 25mA minimum
• Voltage rating: 24VDC
• Contact material and finish must support the same electrical performance envelope

Mechanical Equivalence Requirements:

• Surface mount assembly method
• Gull wing termination style
• 0.050" (1.27mm) half pitch spacing
• Slide actuator with flush/recessed profile
• Dimensions compatible with standard DIP switch footprints

Compliance Requirements:

• RoHS3 compliance status
• MSL 1 rating (unlimited moisture sensitivity)
• REACH unaffected status

The CTS Electrocomponents 218-6LPST meets all mandatory electrical and mechanical criteria for direct substitution in the 97R06T application space.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: Grayhill 97R06T

The 97R06T is the specified component and remains the first choice when available. Current inventory status shows 995 pieces in stock. This part is Active in production with full regulatory compliance (RoHS3, REACH unaffected, EAR99 classification).

Substitute Selection: CTS Electrocomponents 218-6LPST

The 218-6LPST qualifies as a direct electrical and mechanical substitute based on:

• Identical SPST 6-position circuit configuration
• Matching 25mA/24VDC electrical ratings
• Compatible surface mount assembly with gull wing termination and 0.050" pitch
• Equivalent gold-plated contact finish
• Identical RoHS3 and REACH compliance status
• Extended operating temperature range (-55°C vs. -40°C minimum)
• Higher inventory availability (11,964 pieces in stock)

Physical Dimension Consideration:

The 218-6LPST has a greater height above board (0.104" vs. 0.061"). This difference must be evaluated against enclosure clearance requirements. If vertical space is constrained, the 97R06T remains mandatory. If clearance exists, the 218-6LPST is mechanically compatible.

Washable Feature Difference:

The 218-6LPST includes epoxy sealed terminals and tape seal features, making it washable. The 97R06T is not washable. This difference is relevant only if post-assembly cleaning processes are specified.

Frequently Asked Questions (FAQ)

Q: Can the CTS 218-6LPST replace the Grayhill 97R06T in all applications?

A: The 218-6LPST is electrically and mechanically equivalent for standard DIP switch applications. However, verify two factors: (1) Enclosure clearance for the increased height (0.104" vs. 0.061"), and (2) Whether washable characteristics are required or prohibited by your assembly process.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution requires matching: circuit type (SPST), position count (6), current rating (25mA minimum), voltage rating (24VDC), surface mount assembly method, gull wing termination, 0.050" pitch spacing, and slide actuator profile. Contact material and finish must support equivalent electrical performance.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) ratings. No compliance barriers exist for substitution.

Q: What is the significance of the operating temperature range difference?

A: The 218-6LPST operates from -55°C to 85°C, while the 97R06T operates from -40°C to 85°C. The 218-6LPST provides extended low-temperature capability. If your application requires operation below -40°C, only the 218-6LPST is suitable. For standard -40°C to 85°C applications, both parts are equivalent.

Q: Does the washable feature affect electrical performance?

A: No. The washable feature (epoxy sealed terminals and tape seal on the 218-6LPST) is a manufacturing and assembly process consideration, not an electrical specification. It does not impact switching performance or electrical ratings.

Q: Are the footprints identical for PCB layout?

A: Yes. Both parts use identical pitch (0.050" half spacing), gull wing termination, and surface mount assembly. PCB footprints are interchangeable. The only layout consideration is vertical clearance due to the height difference.

Q: What inventory considerations apply?

A: The 97R06T has 995 pieces in stock. The 218-6LPST has 11,964 pieces available. If supply continuity is a concern, the 218-6LPST offers significantly higher availability.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided enclosure clearance accommodates the 218-6LPST's greater height. No circuit redesign or PCB layout modification is required. Both parts are drop-in compatible from an electrical standpoint.
