SD05H0K DIP Switch Equivalent & Substitute Parts

Part Overview

The SD05H0K is a 5-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 slide actuator operation. The SD05H0K is classified as obsolete product status, making identification of compatible substitute parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

The SD05H0B qualifies as a direct substitute for the SD05H0K based on the following critical parameters that determine functional compatibility:

• Circuit configuration (SPST) remains identical
• Number of positions (5) is unchanged
• Current rating (100mA) and voltage rating (25VDC) are maintained
• Actuator type (Slide Standard) and actuator level (Flush, Recessed) are consistent
• Mounting type (Through Hole) and termination style (PC Pin) are preserved
• Pitch spacing (0.100" / 2.54mm) and height above board (0.178" / 4.52mm) are identical
• Operating temperature range (-40°C to 85°C) is the same
• Mechanical and electrical life ratings (2,000 Cycles) are equivalent

Variations between the parts are limited to contact material composition (Copper Alloy versus Beryllium Copper), body material (PBT versus PPA), and regulatory compliance status, which do not affect electrical or mechanical substitution capability within the specified operating parameters.

Parameter Comparison

Engineering Selection Recommendations

The SD05H0B is the appropriate substitute for the obsolete SD05H0K. Both components maintain identical electrical and mechanical specifications across all critical parameters including circuit configuration, current and voltage ratings, actuator characteristics, and physical dimensions.

The SD05H0B offers the additional advantage of active product status, ensuring continued availability and supply chain support. The component achieves ROHS3 compliance, whereas the SD05H0K is non-compliant. For applications subject to RoHS regulatory requirements, the SD05H0B is the required selection. Both parts maintain equivalent REACH and ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Can SD05H0B directly replace SD05H0K in existing designs?

A: Yes. The SD05H0B maintains identical electrical ratings (100mA at 25VDC), circuit configuration (SPST), physical dimensions (0.178" height, 0.100" pitch), and mechanical life specifications (2,000 cycles). Through-hole mounting and PC pin termination are preserved, enabling direct PCB layout compatibility.

Q: What are the material differences between these parts?

A: The SD05H0K uses Copper Alloy contacts with PBT body material. The SD05H0B uses Beryllium Copper contacts with PPA body material. Both configurations maintain gold contact finish and equivalent electrical performance within the specified operating parameters.

Q: Does packaging differ between these parts?

A: The SD05H0K is supplied with dash packaging, while the SD05H0B is supplied in Tube packaging. This distinction affects procurement and handling procedures but does not impact component functionality or electrical characteristics.

Q: Why is RoHS compliance status different?

A: The SD05H0K predates RoHS3 requirements and is classified as non-compliant. The SD05H0B is manufactured to current ROHS3 standards. For applications requiring regulatory compliance with RoHS directives, the SD05H0B is the appropriate selection.

Q: Are operating temperature ranges identical?

A: Yes. Both the SD05H0K and SD05H0B operate across the identical temperature range of -40°C to 85°C, with equivalent mechanical and electrical life ratings of 2,000 cycles.
