Grayhill 97R10S DIP Switch - Equivalent & Substitute Parts

Part Overview

The Grayhill 97R10S is a surface mount DIP switch featuring SPST (Single Pole Single Throw) configuration with 10 positions, rated for 25mA at 24VDC. This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing production support and design continuity. The 97R10S serves applications requiring reliable switching functionality in compact form factors with standard slide actuators and gold-plated copper alloy contacts.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Grayhill 97R10S is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Circuit configuration (SPST), number of positions (10), current rating (25mA), and voltage rating (24VDC) must remain identical. These parameters define the functional switching capability and load-handling characteristics.

Mechanical Parameters: Actuator type (Slide Standard), mounting type (Surface Mount), termination style (Gull Wing), pitch (0.050" Half), and height above board (0.061") must match to ensure PCB compatibility and assembly process alignment.

Material & Environmental Parameters: Contact material (Copper Alloy), contact finish (Gold), body material (Polyamide/Nylon), operating temperature range (-40°C to 85°C), and mechanical life (1,000 cycles) establish reliability and environmental performance boundaries.

Packaging & Compliance: While packaging format may vary (tape seal configuration), RoHS and REACH compliance status are noted as differentiating factors between obsolete and active product variants.

Parameter Comparison

Engineering Selection Recommendations

The Grayhill 97R10ST serves as the direct functional equivalent to the obsolete 97R10S. All electrical, mechanical, and environmental parameters are identical, ensuring drop-in compatibility at the component level.

Product Status Consideration: The 97R10S is classified as obsolete, while the 97R10ST is active. For new designs or production continuity, the 97R10ST is the appropriate selection.

Compliance Differentiation: The 97R10S is RoHS non-compliant, whereas the 97R10ST achieves ROHS3 compliance. For applications subject to RoHS directives or customer compliance requirements, the 97R10ST is mandatory. Both parts maintain REACH Unaffected status and EAR99 export classification.

Packaging: The 97R10ST is supplied in bulk packaging, whereas the 97R10S packaging format is not specified. Verify packaging requirements against procurement and assembly processes.

Inventory & Availability: Current stock levels show 916 units of 97R10ST available, supporting production requirements for immediate deployment.

Frequently Asked Questions (FAQ)

Q: Can the 97R10ST directly replace the 97R10S in existing designs?

A: Yes. The 97R10ST is electrically and mechanically identical to the 97R10S across all specified parameters including circuit configuration, current/voltage ratings, actuator type, mounting, termination, pitch, and height. PCB layouts and assembly processes require no modification.

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

A: The 97R10S is obsolete and RoHS non-compliant, while the 97R10ST is an active product with ROHS3 compliance. Functionally, they are equivalent.

Q: Are there any compatibility concerns with the 97R10ST substitution?

A: No compatibility concerns exist. All mechanical dimensions, electrical ratings, contact materials, and environmental specifications are identical. The parts are interchangeable at the component level.

Q: Does the 97R10ST meet RoHS requirements?

A: Yes. The 97R10ST is ROHS3 compliant. If your application or customer requirements mandate RoHS compliance, the 97R10ST satisfies this requirement, whereas the 97R10S does not.

Q: What is the pitch specification, and why does it matter?

A: Both parts feature a 0.050" (1.27mm) half-pitch. This specification determines PCB footprint spacing and is critical for assembly compatibility. The identical pitch ensures no PCB redesign is necessary.

Q: Are the contact materials the same?

A: Yes. Both parts use copper alloy contacts with gold finish, ensuring equivalent electrical performance, corrosion resistance, and signal integrity.

Q: What is the operating temperature range?

A: Both the 97R10S and 97R10ST operate across -40°C to 85°C, supporting industrial and commercial temperature environments.

Q: Is the 97R10ST washable?

A: Yes. The 97R10ST is washable with tape seal features, matching the 97R10S specification for post-assembly cleaning processes.
