SD10H0K DIP Switch Equivalent & Substitute Parts

Part Overview

The SD10H0K is a 10-position DIP switch manufactured by C&K, featuring SPST (Single Pole Single Throw) circuit configuration with 100mA current rating at 25VDC. This component is designed for through-hole mounting applications requiring manual slide actuation with flush, recessed actuator positioning.

The SD10H0K is classified as obsolete. Locating equivalent substitute parts is necessary to support legacy system maintenance, board redesigns, and procurement continuity where original inventory is depleted or unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SD10H0K is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPST)
• Number of positions (10)
• Current rating (100mA)
• Voltage rating (25VDC)
• Actuator type and level (Slide, Flush/Recessed)
• Mounting type (Through Hole)
• Pitch spacing (0.100" / 2.54mm)
• Physical dimensions (Height, Length)
• Termination style (PC Pin)
• Operating temperature range (-40°C to 85°C)
• Mechanical and electrical life ratings (2,000 Cycles)

The SD10H0B qualifies as a direct substitute based on full alignment with these parameters. Contact material and body material variations do not affect functional substitutability within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

The SD10H0B is the qualified substitute for the SD10H0K. Both parts maintain identical electrical and mechanical specifications across all critical parameters.

The SD10H0B offers the advantage of active product status, ensuring ongoing availability and supply chain support. Additionally, the SD10H0B achieves ROHS3 compliance, whereas the SD10H0K is RoHS non-compliant. For new designs or systems requiring regulatory compliance with current environmental standards, the SD10H0B is the appropriate selection.

For legacy system maintenance where original SD10H0K components are unavailable, the SD10H0B provides functional equivalence without circuit board modification or redesign.

Frequently Asked Questions (FAQ)

Q: Can the SD10H0B replace the SD10H0K in existing applications?

A: Yes. The SD10H0B is functionally equivalent to the SD10H0K across all electrical and mechanical parameters. Both parts share identical circuit configuration, current and voltage ratings, actuator characteristics, mounting type, pitch spacing, and physical dimensions. Direct substitution is possible without board-level modifications.

Q: What is the difference between the SD10H0K and SD10H0B?

A: The primary differences are product status and regulatory compliance. The SD10H0K is obsolete and RoHS non-compliant. The SD10H0B is an active product with ROHS3 compliance. Contact material differs (Copper Alloy in SD10H0K versus Beryllium Copper in SD10H0B) and body material differs (PBT versus PPA), but these variations do not affect functional performance within the specified operating parameters.

Q: Are there packaging differences between these parts?

A: The SD10H0K is supplied with standard packaging. The SD10H0B is supplied in Tube packaging. Both packaging formats are suitable for through-hole assembly processes.

Q: What compliance certifications apply to these parts?

A: Both parts carry REACH Unaffected status and EAR99 ECCN classification. The SD10H0B additionally meets ROHS3 compliance requirements. The SD10H0K does not meet current RoHS standards.

Q: Are these parts suitable for washable applications?

A: Yes. Both the SD10H0K and SD10H0B are rated as washable and feature Tape Seal protection, making them suitable for post-assembly cleaning processes.
