Grayhill 97C08S DIP Switch Equivalent & Substitute Parts

Part Overview

The Grayhill 97C08S is an 8-position surface mount DIP switch with SPST circuit configuration, rated for 25mA at 24VDC. This component features a slide actuator with flush, recessed positioning and gold-plated copper alloy contacts suitable for configuration and control applications in electronic assemblies.

The 97C08S carries an obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for legacy systems or redesign initiatives.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 97C08S DIP switch are identified based on strict electrical and mechanical parameter matching within the allowed specifications for this product category.

Primary Substitution Criteria:

• Circuit configuration: SPST
• Position count: 8
• Current rating: 25mA
• Voltage rating: 24VDC
• Actuator type: Slide (Standard)
• Mounting type: Surface Mount
• Termination style: Gull Wing
• Pitch: 0.050" (1.27mm), Half

Substitute Classification:

Direct Manufacturer Equivalent (97C08ST): Grayhill Inc. part number 97C08ST maintains identical electrical specifications and mechanical form factor as the 97C08S. This part differs only in packaging format (Tube versus standard packaging) and product status (Active versus Obsolete). The 97C08ST is the current production equivalent within the Grayhill 97 series.

Similar Manufacturer Substitute (1-1571983-0): TE Connectivity ALCOSWITCH part number 1-1571983-0 (GDH series) meets all core electrical parameters and mounting requirements. Physical dimensions and body material differ within acceptable tolerances for surface mount DIP switch applications. This part is actively produced and RoHS3 compliant.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Manufacturer): The Grayhill 97C08ST is the recommended substitute for the obsolete 97C08S. Both parts are manufactured by Grayhill Inc. and share identical electrical and mechanical specifications. The 97C08ST is actively produced and available in higher inventory quantities. Selection of 97C08ST eliminates supply chain risk associated with the obsolete 97C08S designation.

For Cross-Manufacturer Substitution: The TE Connectivity 1-1571983-0 provides functional equivalence for applications where cross-manufacturer sourcing is acceptable. This part meets all core electrical requirements and mounting specifications. The 1-1571983-0 features RoHS3 compliance and active production status, supporting long-term availability.

Compliance Considerations: The 97C08S is RoHS non-compliant. Both substitute parts (97C08ST and 1-1571983-0) are RoHS3 compliant, supporting regulatory requirements for new designs or redesign initiatives. The 1-1571983-0 carries REACH Unaffected status, while the 97C08ST maintains REACH Unaffected designation consistent with the original part.

Physical Dimension Tolerance: The TE Connectivity 1-1571983-0 exhibits a 0.028" (0.70mm) increase in height above board compared to the Grayhill parts. This dimension difference must be evaluated against specific PCB layout and enclosure clearance requirements before selection.

Frequently Asked Questions (FAQ)

Q: Can the 97C08ST directly replace the 97C08S without PCB layout modifications?

A: Yes. The 97C08ST maintains identical electrical specifications, mechanical form factor, and mounting footprint as the 97C08S. No PCB layout changes are required for direct substitution.

Q: What is the primary reason for the 97C08S obsolescence?

A: The 97C08S is designated obsolete by Grayhill Inc. The 97C08ST serves as the current production equivalent within the 97 series DIP switch family.

Q: Does the TE Connectivity 1-1571983-0 require PCB layout modifications?

A: The 1-1571983-0 maintains the same pitch (0.050" half) and gull wing termination as the 97C08S. However, the increased height above board (0.091" versus 0.063") must be verified against PCB clearance and enclosure design constraints. Footprint compatibility should be confirmed before implementation.

Q: Are there electrical performance differences between the Grayhill 97C08ST and TE Connectivity 1-1571983-0?

A: Both parts meet the 25mA at 24VDC electrical specification. The TE Connectivity part specifies 1,000 electrical life cycles, while the Grayhill parts do not provide electrical life data. Both parts support 1,000 mechanical life cycles.

Q: What packaging formats are available for these substitute parts?

A: The 97C08ST is supplied in Tube packaging. The 1-1571983-0 is supplied in Tube packaging. Packaging format selection should align with assembly process requirements and inventory management procedures.

Q: Are both substitute parts suitable for applications requiring RoHS compliance?

A: Yes. Both the 97C08ST and 1-1571983-0 are RoHS3 compliant. The original 97C08S is RoHS non-compliant and should not be used in applications with RoHS regulatory requirements.

Q: What is the operating temperature range difference between these parts?

A: The Grayhill 97C08S and 97C08ST support -40°C to 85°C operation. The TE Connectivity 1-1571983-0 supports -30°C to 85°C operation. Applications requiring operation below -30°C must use the Grayhill parts.

Q: Can these DIP switches be used interchangeably in existing production assemblies?

A: The 97C08ST provides direct interchangeability with the 97C08S. The 1-1571983-0 requires verification of height clearance and operating temperature requirements before implementation in existing assemblies.
