Grayhill 97R08SR DIP Switch Equivalent & Substitute Parts

Part Overview

The Grayhill 97R08SR is an 8-position surface mount DIP switch with SPST (Single Pole Single Throw) circuit configuration, rated for 25mA at 24VDC. This component features a slide actuator with standard (flush, recessed) positioning and gold-plated copper alloy contacts suitable for applications requiring reliable switching in compact form factors.

The 97R08SR is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 97R08SR is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically for a part to function as a direct substitute:

Electrical Parameters:

• Circuit configuration (SPST)
• Number of positions (8)
• Current rating (25mA)
• Voltage rating (24VDC)

Mechanical Parameters:

• Actuator type (Slide, Standard)
• Mounting type (Surface Mount)
• Termination style (Gull Wing)
• Pitch (0.050" / 1.27mm, Half)
• Height above board (0.061" / 1.55mm)

Material & Environmental Parameters:

• Contact material (Copper Alloy)
• Contact finish (Gold)
• Operating temperature range (-40°C to 85°C)
• Mechanical life (1,000 Cycles)
• RoHS compliance (ROHS3)

The primary distinction between the main part and its substitute relates to product status and packaging configuration, not functional or physical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 97R08SRT serves as a direct functional and mechanical equivalent to the 97R08SR. Both parts are manufactured by Grayhill Inc. within the 97 series and share identical electrical specifications, physical dimensions, and material compositions.

Product Status Consideration: The 97R08SR is classified as obsolete, while the 97R08SRT maintains active product status. For new designs, ongoing production, or component replenishment, the 97R08SRT is the appropriate selection to ensure continued availability and manufacturer support.

Compliance & Certification: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications.

Packaging Difference: The primary distinction between these parts is packaging configuration. The 97R08SR is supplied in standard packaging, while the 97R08SRT is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and high-volume production environments. For manual assembly or low-volume applications, standard packaging may be preferred, but functional performance remains identical.

Frequently Asked Questions (FAQ)

Q: Can the 97R08SRT directly replace the 97R08SR in existing designs?

A: Yes. The 97R08SRT is electrically and mechanically identical to the 97R08SR. All electrical parameters (25mA, 24VDC, SPST, 8-position), physical dimensions (0.061" height, 0.050" pitch), contact materials (gold-plated copper alloy), and environmental ratings (-40°C to 85°C) are identical. Direct substitution is supported without design modification.

Q: What is the difference between the 97R08SR and 97R08SRT part numbers?

A: The difference is packaging and product status. The 97R08SR uses standard packaging and is obsolete. The 97R08SRT uses Tape & Reel (TR) packaging and maintains active product status. The "T" suffix in 97R08SRT indicates Tape & Reel packaging. Functionally and mechanically, the components are equivalent.

Q: Is Tape & Reel packaging compatible with manual assembly?

A: Tape & Reel packaging is optimized for automated pick-and-place assembly systems. For manual assembly operations, components must be removed from the tape. This adds a manual handling step but does not affect component functionality or performance. The component itself remains identical regardless of packaging format.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the 97R08SR and 97R08SRT maintain identical RoHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level 1 (unlimited). Regulatory and environmental certifications are equivalent.

Q: Why is the 97R08SR listed as obsolete?

A: Product obsolescence typically reflects manufacturer discontinuation decisions based on market demand, production efficiency, or product line consolidation. The 97R08SRT represents the current active equivalent within the Grayhill 97 series DIP switch product line.

Q: Can I mix 97R08SR and 97R08SRT components in the same production batch?

A: Yes. Since both parts are electrically and mechanically identical, they can be used interchangeably within the same assembly or system. However, packaging differences may require separate handling procedures during assembly.

Q: What is the mechanical life specification, and what does it mean?

A: The mechanical life specification of 1,000 cycles indicates the number of actuator position changes the switch is rated to withstand under normal operating conditions. This specification applies to both the 97R08SR and 97R08SRT identically.
