Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Grayhill 97R02RT is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPST
• Number of positions: 2
• Current rating: 25mA
• Voltage rating: 24VDC
• Actuator type: Slide (Standard)
• Actuator level: Flush, Recessed
• Mounting type: Surface Mount
• Termination style: Gull Wing
• Pitch: 0.050" (1.27mm), Half
• Contact finish: Gold
• Moisture Sensitivity Level: 1 (Unlimited)

The CTS Electrocomponents 218-2LPSTR satisfies all mandatory matching parameters and qualifies as a direct functional equivalent. Both parts operate identically within the specified electrical and mechanical constraints and are suitable for direct substitution in circuit designs.

Engineering Selection Recommendations

Grayhill 97R02RT Selection Criteria:

• Primary choice when mechanical life specification of 1,000 cycles is a documented design requirement
• Preferred for applications with strict height constraints (0.061" above board)
• Suitable for standard industrial temperature range (-40°C to 85°C)
• RoHS Compliant status meets regulated procurement standards

CTS Electrocomponents 218-2LPSTR Selection Criteria:

• Suitable alternative when extended operating temperature range (-55°C to 85°C) is required
• Appropriate for applications requiring washable component capability with epoxy sealed terminals
• Electrical life specification of 1,000 cycles supports switching cycle requirements
• ROHS3 Compliant status meets current regulatory requirements
• Higher inventory availability (6,696 pcs) supports rapid procurement

Both parts maintain identical electrical performance (25mA at 24VDC SPST operation) and are RoHS/REACH compliant. Selection between these equivalents depends on specific application constraints regarding temperature range, washability, and physical height limitations.

Frequently Asked Questions (FAQ)

Q: Can the CTS 218-2LPSTR directly replace the Grayhill 97R02RT in existing designs?

A: Yes, the CTS 218-2LPSTR is a direct functional equivalent for SPST switching applications at 25mA and 24VDC. Both parts share identical circuit configuration, current/voltage ratings, actuator type, and termination specifications. Physical height difference (0.061" vs 0.104" above board) must be verified against PCB layout constraints before substitution.

Q: What is the significance of the different contact materials (Copper Alloy vs Beryllium Copper)?

A: Both contact materials are gold-finished and rated for identical electrical performance at 25mA and 24VDC. Contact material differences do not affect functional equivalence for this application category. Material selection reflects manufacturer design choices and does not impact switching reliability or electrical characteristics.

Q: Why does the Grayhill part specify mechanical life while the CTS part specifies electrical life?

A: Both specifications indicate 1,000 cycles of operational life. Mechanical life refers to physical actuator movement cycles, while electrical life refers to switching cycles under load. For SPST DIP switch applications, these metrics are functionally equivalent and both parts support the same operational cycle count.

Q: Are there packaging differences between these parts?

A: The Grayhill 97R02RT is supplied in standard packaging (not specified), while the CTS 218-2LPSTR is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for high-volume surface mount assembly and does not affect component functionality or performance.

Q: Which part should be selected for applications requiring washable components?

A: The CTS 218-2LPSTR includes washable capability with epoxy sealed terminals and tape seal features. The Grayhill 97R02RT is not washable. For applications requiring post-assembly cleaning processes, the CTS part is the appropriate selection.

Q: Do both parts meet current regulatory compliance standards?

A: Yes. The Grayhill 97R02RT is RoHS Compliant and REACH Unaffected. The CTS 218-2LPSTR is ROHS3 Compliant and REACH Unaffected. Both parts satisfy current regulatory requirements for industrial and commercial applications. ROHS3 represents the current revision of RoHS compliance standards.
