DHS6C Equivalent & Substitute Parts

Part Overview

The DHS6C is a 6-position DIP slide switch manufactured by APEM Inc., designed for surface mount applications with SPST (Single Pole Single Throw) circuit configuration. This component operates at 6VDC with a 100mA current rating and features a standard slide actuator with flush, recessed actuation level. The DHS6C is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DHS6C is determined by the following critical parameters:

• Circuit Configuration: Must be SPST to maintain single-pole, single-throw switching functionality
• Number of Positions: Must be 6 to ensure pin-count and footprint compatibility
• Actuator Type: Must be Slide (Standard) to preserve mechanical interface and user interaction
• Mounting Type: Must be Surface Mount to maintain PCB assembly compatibility
• Pitch and Height: Must match 0.050" (1.27mm) half-pitch and 0.087" (2.20mm) height to ensure footprint compatibility
• Termination Style: Must be Gull Wing to maintain solder connection geometry
• Contact Material and Finish: Must support gold-plated contacts for reliable electrical performance

The DHS6-A from APEM Inc. meets these core mechanical and electrical interface requirements. However, voltage and current ratings differ, requiring application-level verification of circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

The DHS6-A qualifies as a mechanical and functional substitute for the DHS6C based on matching circuit configuration, position count, actuator type, mounting method, and physical footprint. Both components are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent environmental performance.

The primary distinction is product status: the DHS6C is obsolete while the DHS6-A is active, providing supply chain continuity and ongoing manufacturer support. The DHS6-A operates at higher voltage (24VDC versus 6VDC) and lower current (25mA versus 100mA), requiring circuit-level compatibility assessment. The DHS6-A also features an extended operating temperature range (-40°C ~ 85°C versus -40°C ~ 80°C), providing marginally improved thermal performance.

Selection of the DHS6-A is appropriate for applications where the 24VDC voltage and 25mA current specifications align with system requirements. For applications strictly requiring 6VDC and 100mA operation, alternative substitutes within the DHS series or from competing manufacturers must be evaluated.

Frequently Asked Questions (FAQ)

Q: Can the DHS6-A directly replace the DHS6C in existing designs?

A: Mechanical and electrical interface compatibility is confirmed. However, the DHS6-A operates at 24VDC with 25mA maximum current, while the DHS6C operates at 6VDC with 100mA capacity. Direct substitution requires verification that the application circuit operates at 24VDC and does not exceed 25mA per switch position.

Q: Are the footprints identical between DHS6C and DHS6-A?

A: Yes. Both components share identical pitch (0.050" / 1.27mm half-pitch), height above board (0.087" / 2.20mm), mounting type (surface mount), and termination style (gull wing). PCB layout modifications are not required.

Q: What is the significance of the DHS6C being obsolete?

A: Obsolete status indicates the DHS6C is no longer manufactured or supported by APEM Inc. The DHS6-A, classified as active, represents the current production equivalent within the DHS series and ensures ongoing availability and manufacturer technical support.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the DHS6C and DHS6-A are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1, Unlimited). Regulatory and environmental compliance requirements are equivalent.

Q: What is the difference in contact material between these parts?

A: The DHS6C uses beryllium copper contacts, while the DHS6-A uses copper alloy contacts. Both are gold-plated and rated for 1,000 electrical cycles. Contact material differences do not affect mechanical compatibility or standard switching applications.
