Grayhill 97R02T DIP Switch Equivalent & Substitute Parts

Part Overview

The Grayhill 97R02T is an SPST (Single Pole Single Throw) DIP switch designed for surface mount applications. This component features a slide actuator with a 2-position configuration, rated for 25mA at 24VDC operation. The 97R02T is classified as an active product with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits alternative sourcing while maintaining electrical and mechanical compatibility within specified parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Grayhill 97R02T are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Circuit type: SPST (single pole, single throw configuration)
• Position count: 2-position switch
• Current rating: 25mA minimum
• Voltage rating: 24VDC minimum
• Actuator type: Slide (Standard)
• Mounting: Surface Mount
• Termination: Gull Wing
• Pitch: 0.050" (1.27mm) Half spacing
• Contact finish: Gold plating
• Compliance: RoHS3 and REACH status

Allowable Parameter Variations: Substitutes may differ in contact material composition, height above board, body material specification, mechanical life cycles, and operating temperature range, provided the substitute meets or exceeds the minimum electrical requirements and maintains physical compatibility with the PCB footprint.

The CTS Electrocomponents 218-2LPSTR qualifies as a substitute based on matching all critical electrical and mechanical parameters while offering enhanced environmental sealing features.

Engineering Selection Recommendations

Grayhill 97R02T Selection Criteria:

• Primary choice when tube packaging is required for manual assembly or low-volume production
• Specified when copper alloy contact material is a design requirement
• Selected when the narrower height profile (0.061") is critical for PCB clearance constraints
• Preferred when operating temperature range of -40°C to 85°C is sufficient

CTS 218-2LPSTR Selection Criteria:

• Suitable substitute when tape and reel packaging supports automated assembly processes
• Specified when extended operating temperature range (-55°C to 85°C) is required
• Selected when washable/sealed terminal construction provides environmental protection benefits
• Preferred when beryllium copper contact material meets design specifications
• Appropriate when higher inventory availability (6696 pcs vs. 860 pcs) supports supply chain requirements

Both parts maintain full RoHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity rating (MSL 1). Selection between these components should be based on packaging format requirements, assembly methodology, environmental operating conditions, and inventory availability rather than electrical performance, as both parts are electrically equivalent for 24VDC, 25mA SPST switching applications.

Frequently Asked Questions (FAQ)

Q: Can the CTS 218-2LPSTR directly replace the Grayhill 97R02T on an existing PCB?

A: Yes, the CTS 218-2LPSTR is electrically and mechanically compatible. Both parts share identical pitch (0.050" half spacing), gull wing termination, and footprint dimensions within allowable tolerances (length difference: 0.002", height difference: 0.043"). PCB layout verification is recommended to confirm clearance for the slightly taller CTS component (0.104" vs. 0.061").

Q: What is the primary difference between these two switches?

A: The primary differences are packaging format (tube vs. tape & reel), contact material composition (copper alloy vs. beryllium copper), operating temperature range (-40°C to 85°C vs. -55°C to 85°C), and terminal sealing (non-washable vs. washable with epoxy sealed terminals). Electrical performance and switching capacity are identical.

Q: Are both parts RoHS3 compliant?

A: Yes, both the Grayhill 97R02T and CTS 218-2LPSTR are RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: Which part should be selected for automated assembly?

A: The CTS 218-2LPSTR is recommended for automated assembly due to tape and reel packaging format, which is compatible with pick-and-place equipment. The Grayhill 97R02T tube packaging is suitable for manual assembly or lower-volume production processes.

Q: Does the height difference affect component selection?

A: The height difference (0.043") may be significant in space-constrained applications. The Grayhill 97R02T (0.061") is preferred when vertical clearance is limited. The CTS 218-2LPSTR (0.104") requires verification of available board-to-cover clearance. Both heights are within typical surface mount component specifications.

Q: What does MSL 1 (Unlimited) rating mean?

A: MSL 1 (Unlimited) indicates that both components have unlimited shelf life and do not require moisture-controlled storage or baking procedures prior to soldering. These parts can be stored under standard warehouse conditions without degradation.

Q: Can these switches be used in applications requiring washable PCBs?

A: The CTS 218-2LPSTR features epoxy sealed terminals and is rated as washable, making it suitable for post-assembly cleaning processes. The Grayhill 97R02T is not washable and should not be subjected to aqueous cleaning processes after soldering.
