Grayhill 97R02SR DIP Switch Equivalent & Substitute Parts

Part Overview

The Grayhill 97R02SR is a surface mount DIP switch featuring SPST (Single Pole Single Throw) configuration with 2 positions, rated for 25mA at 24VDC. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement continuity. The switch employs a standard 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 Grayhill 97R02SR is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Circuit type (SPST), number of positions (2), current rating (25mA), and voltage rating (24VDC) must remain identical.

Mechanical Parameters: Actuator type (slide standard), mounting method (surface mount), termination style (gull wing), pitch (0.050"), and height above board (0.061") must match exactly.

Material Specifications: Contact material (copper alloy), contact finish (gold), and body material (polyamide/nylon) must be preserved.

Environmental Compliance: Operating temperature range (-40°C to 85°C) and mechanical life (1,000 cycles) establish the performance envelope.

The Grayhill 97R02SRT qualifies as a direct substitute based on complete alignment with all specified parameters. The primary distinction is packaging format and product status, not functional or electrical characteristics.

Engineering Selection Recommendations

The Grayhill 97R02SRT provides complete functional and electrical equivalence to the obsolete 97R02SR. Selection between these parts should be based on the following criteria:

Product Status: The 97R02SRT carries Active status, ensuring continued availability and manufacturing support. The 97R02SR is classified as Obsolete, limiting future procurement options.

Regulatory Compliance: The 97R02SRT achieves ROHS3 compliance, whereas the 97R02SR is RoHS non-compliant. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the 97R02SRT is the appropriate selection.

Packaging Considerations: The 97R02SR is supplied in bulk packaging, while the 97R02SRT is supplied in Tape & Reel format. Packaging selection depends on assembly process requirements and volume specifications.

Electrical and Mechanical Equivalence: Both parts are electrically and mechanically identical across all functional parameters. Direct substitution is permissible without circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can the 97R02SRT replace the 97R02SR in existing designs?

A: Yes. The 97R02SRT is electrically and mechanically equivalent to the 97R02SR. All functional parameters, including circuit configuration, current and voltage ratings, actuator type, mounting method, and termination style are identical. Direct substitution requires no design changes.

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

A: The 97R02SR is obsolete with RoHS non-compliant status and bulk packaging. The 97R02SRT is an active product with ROHS3 compliance and Tape & Reel packaging. Functional performance is identical.

Q: Does the Tape & Reel packaging of the 97R02SRT affect compatibility?

A: No. Tape & Reel packaging is a supply format used for automated assembly processes. It does not alter the electrical or mechanical characteristics of the component. The actual part remains identical to bulk-packaged versions.

Q: Are there any operating temperature or mechanical life differences?

A: No. Both parts operate across the identical temperature range of -40°C to 85°C and maintain 1,000 mechanical cycles of life. Environmental performance is equivalent.

Q: Why should I select the 97R02SRT over the 97R02SR?

A: The 97R02SRT is recommended for new designs and ongoing procurement due to its Active product status, ensuring long-term availability. Additionally, ROHS3 compliance satisfies regulatory requirements in many jurisdictions. The obsolete status of the 97R02SR creates supply chain risk.

Q: Is the gold contact finish maintained in the substitute part?

A: Yes. Both the 97R02SR and 97R02SRT feature gold-plated copper alloy contacts. Contact material and finish specifications are identical.

Q: Can these parts be used in washable applications?

A: Yes. Both parts are rated as washable and feature the same design characteristics suitable for cleaning processes.
