CTS 210-2LPSF DIP Switch Equivalent & Substitute Parts

Part Overview

The CTS 210-2LPSF is an active-status DIP switch designed for through-hole mounting applications requiring single-pole, single-throw (SPST) switching functionality. This component operates at 100mA and 20VDC, featuring a slide actuator with flush, recessed positioning. The part is manufactured with beryllium copper contacts finished in gold, providing reliable electrical performance across industrial temperature ranges. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity for applications where the primary part may be unavailable or where alternative specifications better suit specific design requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CTS 210-2LPSF is determined by strict alignment of the following critical parameters:

• Circuit configuration (SPST required)
• Number of positions (2 positions required)
• Current rating (100mA minimum)
• Voltage rating (20VDC minimum)
• Actuator type (Slide Standard required)
• Mounting type (Through Hole required)
• Pitch spacing (0.100" / 2.54mm required)
• Contact material and finish (Beryllium Copper with Gold finish)
• Operating temperature range (-40°C ~ 85°C minimum)
• RoHS compliance status

The C&K SD02H0B meets all substitution criteria. While the SD02H0B features a higher voltage rating (25VDC) and enhanced mechanical/electrical life specifications (2,000 cycles), these represent improvements over the primary part and do not restrict compatibility in applications designed for the 210-2LPSF.

Parameter Comparison

Engineering Selection Recommendations

Both the CTS 210-2LPSF and C&K SD02H0B are active-status components with full regulatory compliance. Selection between these parts should be based on availability and supply chain requirements rather than functional differences.

The C&K SD02H0B provides enhanced electrical life (2,000 cycles versus 1,000 cycles) and higher voltage rating (25VDC versus 20VDC), making it suitable for applications requiring extended operational cycles or higher voltage margins. The CTS 210-2LPSF remains the primary specification where explicitly required by design documentation.

Both parts maintain identical mechanical interfaces, contact materials, and operating temperature ranges, ensuring direct substitution compatibility in through-hole PCB applications. RoHS3 compliance and REACH unaffected status confirm regulatory alignment for both options.

Frequently Asked Questions (FAQ)

Q: Can the C&K SD02H0B replace the CTS 210-2LPSF in existing designs?

A: Yes. Both parts share identical circuit configuration (SPST), position count (2), current rating (100mA), actuator type (Slide Standard), mounting method (Through Hole), and pitch spacing (0.100"). The SD02H0B's higher voltage rating (25VDC) and extended electrical life (2,000 cycles) represent functional improvements that do not restrict compatibility.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution requires matching circuit configuration, number of positions, current rating, voltage rating (minimum), actuator type, mounting type, pitch spacing, contact material and finish, operating temperature range, and regulatory compliance status. Deviations in any of these parameters disqualify a part from direct substitution.

Q: Are there mechanical compatibility concerns between these parts?

A: No. Both parts feature identical through-hole mounting with 0.100" pitch spacing and nearly identical height above board (0.180" versus 0.178"). PC pin termination style is consistent across both parts, ensuring direct PCB footprint compatibility.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the CTS 210-2LPSF and C&K SD02H0B are ROHS3 compliant, REACH unaffected, classified as EAR99, and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What is the difference in electrical life between these parts?

A: The CTS 210-2LPSF is rated for 1,000 electrical cycles, while the C&K SD02H0B is rated for 2,000 electrical cycles. This difference reflects design variations but does not affect substitution compatibility for applications within the primary part's cycle specification.
