DHS10C Equivalent & Substitute Parts Reference

Part Overview

The DHS10C is a 10-position DIP slide switch manufactured by APEM Inc., rated for 100mA at 6VDC with surface mount gull wing termination. This component features beryllium copper contacts with gold finish, polyphenylene sulfide body material, and operates across -40°C to 80°C. The product is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design requirements and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DHS10C is determined by the following critical parameters:

• Circuit Configuration: Must be SPST (Single Pole Single Throw)
• Number of Positions: Must be 10
• Mounting Type: Must be Surface Mount
• Termination Style: Must be Gull Wing
• Pitch: Must be 0.050" (1.27mm), Half
• Actuator Type: Must be Slide (Standard)

The identified substitute parts maintain these core functional parameters. Variations in current rating, voltage rating, contact material, body material, and operating temperature range are permissible when the application electrical requirements are met or exceeded. All substitute parts identified maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Parameter Comparison

Engineering Selection Recommendations

DHS10-A (APEM Inc.): This part maintains identical mechanical and pitch specifications to the DHS10C while offering extended operating temperature range (-40°C to 85°C). The DHS10-A is classified as active product status, ensuring continued availability and supply chain stability. Current rating is reduced to 25mA at 24VDC; this substitute is suitable only for applications where circuit current requirements do not exceed 25mA. Contact material differs (copper alloy versus beryllium copper), and the part is washable, providing additional process flexibility. ROHS3 compliance and MSL 1 rating are maintained.

218-10LPST (CTS Electrocomponents): This alternative provides the widest operating temperature range (-55°C to 85°C) and maintains beryllium copper contact material matching the original DHS10C. The 218-10LPST is active product status with higher inventory availability (2100 pcs). Height above board is increased to 0.104" (2.65mm), requiring PCB layout verification for clearance compatibility. Current rating is 25mA at 24VDC. Features include epoxy sealed terminals and tape seal. ROHS3 compliance and MSL 1 rating are maintained.

Both substitute parts are suitable for applications where the DHS10C's 100mA/6VDC specification exceeds actual circuit requirements. Selection between DHS10-A and 218-10LPST depends on temperature range requirements, PCB height constraints, and preferred manufacturer.

Frequently Asked Questions (FAQ)

Q: Can DHS10-A or 218-10LPST be used as direct replacements for DHS10C in all applications?

A: Direct substitution is limited to applications where circuit current does not exceed 25mA and operating voltage is compatible with 24VDC rating. The DHS10C is rated for 100mA at 6VDC; both substitutes are rated for 25mA at 24VDC. Verify that your application current draw and voltage requirements fall within the substitute part specifications before implementation.

Q: What is the impact of the height difference between DHS10C (0.087") and 218-10LPST (0.104")?

A: The 218-10LPST has 0.017" greater height above board. This difference requires verification against PCB layout, component clearance requirements, and assembly process constraints. Confirm that the increased height does not create interference with adjacent components or assembly equipment.

Q: Are all three parts pin-compatible?

A: All three parts share identical pitch (0.050" half pitch), termination style (gull wing), and 10-position configuration. Pin compatibility is confirmed for PCB footprint level. However, verify electrical specifications (current and voltage ratings) match your circuit requirements before soldering.

Q: What is the washable feature on DHS10-A?

A: The DHS10-A is marked as washable, indicating compatibility with aqueous cleaning processes during PCB assembly. The DHS10C and 218-10LPST do not specify washable capability. If your manufacturing process includes aqueous cleaning, DHS10-A provides process compatibility advantage.

Q: Do all substitute parts maintain RoHS3 compliance?

A: Yes. DHS10C, DHS10-A, and 218-10LPST are all ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level), ensuring compatibility with modern manufacturing and environmental regulations.

Q: Why is DHS10C classified as obsolete?

A: Product status reflects manufacturer discontinuation. DHS10-A (active, APEM) and 218-10LPST (active, CTS) are currently manufactured and supported, providing long-term supply chain assurance for new designs or redesigns requiring DIP switch functionality.
