Grayhill 97C10S DIP Switch Equivalent & Substitute Parts

Part Overview

The Grayhill 97C10S is a 10-position surface mount DIP switch with SPST circuit configuration, rated for 25mA at 24VDC. This component features a slide actuator with gold-plated copper alloy contacts and is designed for applications requiring reliable switching in compact form factors.

The 97C10S 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

Substitution eligibility for the 97C10S DIP switch is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration (SPST)
• Number of positions (10)
• Current rating (25mA)
• Voltage rating (24VDC)
• Actuator type (Slide, Standard)
• Mounting type (Surface Mount)
• Termination style (Gull Wing)
• Pitch (0.050" / 1.27mm, Half)
• Contact material and finish (Copper Alloy, Gold)
• Mechanical life (1,000 Cycles)

Allowable Variations:

• Product status (Obsolete to Active)
• RoHS compliance level (non-compliant to ROHS3 compliant)
• Packaging format (standard to Tube)
• Minor dimensional tolerances within PCB assembly constraints
• Operating temperature range (within or exceeding original specification)
• Body material composition (Polyamide to Polyphenylene Sulfide)
• Height above board (within assembly clearance limits)

The 97C10S has two identified substitutes: the Grayhill 97C10ST (direct manufacturer upgrade) and the TE Connectivity 1-1571983-3 (cross-manufacturer equivalent).

Parameter Comparison

Engineering Selection Recommendations

97C10ST (Grayhill Inc.) - Recommended Primary Substitute

The 97C10ST is the direct manufacturer equivalent to the obsolete 97C10S. This part maintains identical electrical specifications, mechanical configuration, and physical dimensions. The 97C10ST carries Active product status and achieves ROHS3 compliance, addressing regulatory requirements for new production. Inventory availability (1900 units) supports immediate procurement. This substitute requires no design modification and presents zero compatibility risk for PCB assembly and functional performance.

1-1571983-3 (TE Connectivity ALCOSWITCH) - Secondary Cross-Manufacturer Substitute

The TE Connectivity 1-1571983-3 provides functional equivalence with identical electrical ratings and circuit configuration. This part is manufactured by an established alternative supplier and maintains Active product status with ROHS3 compliance. The 1-1571983-3 exhibits minor dimensional variations: height above board increases from 0.063" to 0.091" (0.028" difference), and body material changes from Polyamide to Polyphenylene Sulfide. These variations remain within standard PCB assembly tolerances and do not affect electrical performance. Operating temperature range narrows from -40°C to -30°C minimum, which may be relevant for extreme cold-temperature applications. Inventory availability (3300 units) is the highest among all options. This substitute is suitable for applications where cross-manufacturer sourcing is acceptable and dimensional clearance permits the increased height.

Selection Criteria Summary:

• For direct replacement with zero design change: Select 97C10ST
• For maximum supply chain flexibility and inventory: Select 1-1571983-3 after confirming PCB clearance for 0.091" height
• For legacy systems requiring exact original specifications: 97C10S inventory (824 units) remains available as original stock

Frequently Asked Questions (FAQ)

Q: Can the 97C10ST be used as a direct drop-in replacement for the 97C10S?

A: Yes. The 97C10ST is electrically and mechanically identical to the 97C10S. Both parts share the same footprint, pitch, termination style, and electrical ratings. No PCB redesign or firmware modification is required. The primary difference is product status (Active vs. Obsolete) and RoHS compliance level.

Q: What is the significance of the height difference between 97C10S/97C10ST (0.063") and 1-1571983-3 (0.091")?

A: The 0.028" height increase in the TE Connectivity part must be verified against PCB assembly clearance specifications. If the design includes conformal coating, potting, or component stacking above the DIP switch, this dimensional change may create interference. Confirm clearance before selecting this substitute.

Q: Are there electrical performance differences between the Grayhill and TE Connectivity parts?

A: Both parts meet the same electrical specifications: 25mA at 24VDC, SPST configuration, 10 positions, and 1,000-cycle mechanical life. The TE Connectivity part specifies 1,000-cycle electrical life, while the Grayhill parts do not specify this parameter. This difference does not indicate reduced performance; it reflects different datasheet documentation practices.

Q: Does the body material change from Polyamide to Polyphenylene Sulfide affect performance?

A: No. Polyphenylene Sulfide (PPS) is a higher-performance engineering polymer with superior thermal and chemical resistance compared to Polyamide. This material change represents an upgrade in durability and environmental resistance. Both materials are suitable for the specified operating temperature range and washable applications.

Q: What is the impact of the operating temperature range difference (-40°C vs. -30°C minimum)?

A: The 97C10S and 97C10ST support operation down to -40°C, while the TE Connectivity 1-1571983-3 supports operation down to -30°C. If the application requires operation below -30°C, the TE Connectivity part is not suitable. For applications within -30°C to +85°C, both parts are equivalent.

Q: Are all three parts RoHS compliant?

A: The 97C10S is RoHS non-compliant. Both the 97C10ST and 1-1571983-3 are ROHS3 compliant. For new designs or production requiring RoHS compliance, select either the 97C10ST or 1-1571983-3.

Q: What packaging formats are available?

A: The 97C10S is supplied in standard packaging. The 97C10ST and 1-1571983-3 are supplied in Tube packaging, which is standard for high-volume production and automated assembly processes.

Q: Can I mix these parts in the same production batch?

A: Mixing 97C10ST and 1-1571983-3 in the same batch is not recommended due to the 0.028" height difference. This variation may cause assembly equipment calibration issues or create inconsistent solder joint profiles. Maintain part consistency within a single production run. The 97C10S should not be mixed with either substitute due to obsolete status and compliance differences.

Q: Which substitute offers the best long-term supply security?

A: The TE Connectivity 1-1571983-3 offers the highest inventory availability (3300 units) and is manufactured by a major global connector supplier with established distribution networks. The 97C10ST, while directly from the original manufacturer, carries lower inventory (1900 units). For long-term production programs, the TE Connectivity part provides greater supply chain resilience.
