SDA06H0K Equivalent & Substitute Parts

Part Overview

The SDA06H0K is a DIP switch manufactured by C&K, featuring a 6-position SPST configuration with a slide actuator rated for 25mA at 24VDC. This component is designed for through-hole mounting applications requiring reliable switching in industrial and commercial environments. The product is currently obsolete, making identification of compatible substitutes essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SDA06H0K is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPST)
• Number of positions (6)
• Current rating (25mA minimum)
• Voltage rating (24VDC minimum)
• Mounting type (Through Hole)
• Pitch spacing (0.100" / 2.54mm)
• Actuator type (Slide, Standard)
• Contact material and finish compatibility

Two substitute parts meet these criteria:

SDA06H0B (Direct Manufacturer Substitute): Same manufacturer (C&K), identical series designation, matching all electrical and mechanical specifications. Primary difference is product status (Active vs. Obsolete) and improved RoHS3 compliance.

1-1825002-0 (Cross-Manufacturer Substitute): TE Connectivity ALCOSWITCH equivalent with matching SPST 6-position configuration, through-hole mounting, and standard slide actuator. Electrical specifications align with application requirements.

Parameter Comparison

Engineering Selection Recommendations

SDA06H0B is the primary substitute for new designs and ongoing support. As an active product from the original manufacturer with identical electrical and mechanical specifications, it provides direct functional equivalence. The extended operating temperature range (-40°C to 85°C versus -20°C to 85°C) offers improved performance margin in temperature-sensitive applications. ROHS3 compliance addresses regulatory requirements for new product certifications.

1-1825002-0 serves as a secondary cross-manufacturer alternative when SDA06H0B availability is constrained. TE Connectivity ALCOSWITCH maintains the critical SPST 6-position through-hole configuration with standard slide actuator. This option is suitable for applications where cross-manufacturer sourcing is acceptable and inventory availability is prioritized.

Frequently Asked Questions (FAQ)

Q: Can SDA06H0B directly replace SDA06H0K without PCB modifications?

A: Yes. Both components share identical pitch spacing (0.100" / 2.54mm), through-hole termination, and physical mounting footprint. No PCB layout changes are required.

Q: What is the primary reason to substitute the obsolete SDA06H0K?

A: The SDA06H0K is no longer manufactured. SDA06H0B provides continued access to equivalent functionality from the original manufacturer with active production status.

Q: Are there differences in mechanical life between SDA06H0K and SDA06H0B?

A: Both components specify 1,000 mechanical and electrical cycles. No performance degradation occurs with substitution.

Q: Does SDA06H0B meet modern regulatory compliance requirements?

A: Yes. SDA06H0B is ROHS3 compliant and REACH unaffected, addressing current environmental and safety standards. The original SDA06H0K is RoHS non-compliant.

Q: What packaging differences exist between substitutes?

A: SDA06H0K uses standard packaging (dash notation). SDA06H0B is supplied in Tube packaging. 1-1825002-0 is supplied in Bulk packaging. Packaging does not affect component functionality or PCB compatibility.

Q: Is the TE Connectivity 1-1825002-0 electrically equivalent for 25mA 24VDC applications?

A: The 1-1825002-0 maintains SPST 6-position through-hole configuration with standard slide actuator. Specific current and voltage ratings are not provided in available documentation. Verification against application requirements is necessary before selection.

Q: Can both substitutes be used interchangeably in the same design?

A: Yes, for applications where the documented electrical specifications of each part meet system requirements. SDA06H0B is recommended as the primary choice due to complete specification alignment with the original SDA06H0K.
