Grayhill 97R04S DIP Switch Equivalent & Substitute Parts

Part Overview

The Grayhill 97R04S is a surface mount DIP switch featuring SPST (Single Pole Single Throw) configuration with 4 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 97R04S employs 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 Grayhill 97R04S is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Circuit configuration (SPST), number of positions (4), current rating (25mA), and voltage rating (24VDC) must remain identical. These parameters define the functional electrical behavior within the target application.

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 physical compatibility with existing PCB layouts and assembly processes.

Material & Environmental Parameters: Contact material (Copper Alloy), contact finish (Gold), body material (Polyamide/Nylon), washability, and operating temperature range (-40°C to 85°C) must be maintained to preserve reliability and environmental performance.

The 97R04ST qualifies as a direct substitute based on complete alignment across all these parameters.

Parameter Comparison

Engineering Selection Recommendations

The 97R04ST is the direct functional equivalent of the 97R04S across all electrical, mechanical, and environmental parameters. The primary distinction is product status: the 97R04S is obsolete while the 97R04ST is active, ensuring continued availability and manufacturing support.

From a regulatory perspective, the 97R04ST provides an additional advantage through ROHS3 compliance, whereas the 97R04S is RoHS non-compliant. For new designs or redesigns subject to RoHS requirements, the 97R04ST is the appropriate selection. Both parts maintain identical REACH and ECCN classifications (REACH Unaffected, EAR99).

Packaging differs between the two parts: the 97R04S is supplied in standard packaging while the 97R04ST is supplied in Tube packaging. This distinction affects procurement and handling procedures but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the 97R04ST directly replace the 97R04S in existing designs?

A: Yes. The 97R04ST provides complete electrical and mechanical equivalence to the 97R04S. All critical parameters including circuit configuration, current/voltage ratings, actuator type, mounting configuration, and environmental specifications are identical. Direct substitution is supported without design modification.

Q: What is the primary reason for substituting the 97R04S?

A: The 97R04S is classified as obsolete. The 97R04ST is the active equivalent part from Grayhill Inc., ensuring continued procurement availability and manufacturing support for this DIP switch configuration.

Q: Does the 97R04ST meet RoHS requirements?

A: Yes. The 97R04ST is ROHS3 compliant, whereas the 97R04S is RoHS non-compliant. For applications subject to RoHS directives, the 97R04ST is the required selection.

Q: Are there packaging differences between these parts?

A: Yes. The 97R04S uses standard packaging while the 97R04ST is supplied in Tube packaging. This affects procurement, storage, and assembly handling but does not impact component performance or compatibility.

Q: What are the key electrical specifications that define substitution?

A: Substitution is based on SPST circuit configuration, 4-position count, 25mA current rating, and 24VDC voltage rating. Any deviation from these parameters indicates a non-equivalent part.

Q: Are the mechanical dimensions identical?

A: Yes. Both parts share identical pitch (0.050" Half), height above board (0.061"), and gull wing termination style. PCB layouts designed for the 97R04S require no modification for the 97R04ST.

Q: What is the operating temperature range for both parts?

A: Both the 97R04S and 97R04ST operate across -40°C to 85°C, supporting applications in industrial and extended temperature environments.

Q: Is the 97R04ST available in stock?

A: The 97R04ST is listed as active product status with 3,626 pieces in new original stock, providing reliable procurement availability compared to the obsolete 97R04S.
