Grayhill 97R08S DIP Switch - Equivalent & Substitute Parts

Part Overview

The Grayhill 97R08S is an 8-position surface mount DIP switch with SPST (Single Pole Single Throw) circuit configuration, rated for 25mA at 24VDC. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production support and design continuity. The 97R08S features a slide actuator with flush, recessed positioning and gold-plated copper alloy contacts suitable for washable applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 97R08S is based on electrical and mechanical parameter equivalence within the Grayhill 97 series. The substitute part 97R08ST maintains identical specifications across all critical functional parameters: SPST circuit, 8-position configuration, 25mA/24VDC ratings, slide actuator type, surface mount termination, and operating temperature range. The primary distinction is product status and packaging format. Substitution is valid when the following parameters match exactly:

• Circuit type (SPST)
• Number of positions (8)
• Current and voltage ratings (25mA, 24VDC)
• Actuator mechanism (Slide, Standard)
• Mounting technology (Surface Mount)
• Contact material and finish (Copper Alloy, Gold)
• Temperature operating range (-40°C to 85°C)

Parameter Comparison

Engineering Selection Recommendations

The 97R08ST is the direct active equivalent for the obsolete 97R08S. All electrical and mechanical specifications are identical, ensuring functional interchangeability in circuit applications. The 97R08ST maintains ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for new designs and production continuity.

The primary difference between these parts is product status and packaging format. The 97R08S is obsolete with limited inventory availability (639 pieces), while the 97R08ST is active with substantially higher inventory (5,973 pieces) and supplied in tube packaging. For new designs, production ramp-up, or long-term supply chain planning, the 97R08ST is the appropriate selection.

Both parts share identical mechanical footprints, electrical performance characteristics, and environmental ratings. PCB layout, schematic designations, and functional testing protocols require no modification when transitioning from 97R08S to 97R08ST.

Frequently Asked Questions (FAQ)

Q: Can the 97R08ST directly replace the 97R08S in existing designs?

A: Yes. The 97R08ST is electrically and mechanically identical to the 97R08S. All functional parameters, including circuit configuration, current/voltage ratings, actuator type, mounting footprint, and operating temperature range, are equivalent. No design modifications are required.

Q: What is the difference between the 97R08S and 97R08ST?

A: The primary differences are product status and packaging. The 97R08S is obsolete, while the 97R08ST is active. The 97R08S is supplied in tape packaging, while the 97R08ST is supplied in tube packaging. All electrical and mechanical specifications are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and ECCN/HTSUS classifications. Regulatory requirements are met equally by both parts.

Q: What is the inventory status of these parts?

A: The 97R08S (obsolete) has 639 pieces in stock. The 97R08ST (active) has 5,973 pieces in stock. For ongoing production requirements, the 97R08ST is recommended due to higher availability and active product status.

Q: Does packaging format affect electrical performance?

A: No. Tape and tube packaging formats do not affect electrical performance, mechanical life, or functional characteristics. Packaging selection is based on assembly process requirements and inventory management practices.

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

A: Substitution is valid when the following parameters match: circuit type (SPST), number of positions (8), current rating (25mA), voltage rating (24VDC), actuator type (slide standard), mounting type (surface mount), contact material and finish (copper alloy, gold), and operating temperature range (-40°C to 85°C).
