CTS Electrocomponents 210-2ESF Equivalent & Substitute Parts

Part Overview

The CTS Electrocomponents 210-2ESF is an active-status DIP slide switch designed for through-hole mounting applications requiring single-pole, single-throw (SPST) switching functionality. This component operates at 100mA and 20VDC, featuring a raised slide actuator with gold-plated beryllium copper contacts. Finding equivalent substitute parts becomes necessary when managing inventory constraints, lead time requirements, or when sourcing from alternative manufacturers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 210-2ESF is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPST
• Number of positions: 2
• Current rating: 100mA (minimum)
• Voltage rating: 20VDC or higher
• Mounting type: Through Hole
• Pitch: 0.100" (2.54mm)
• Termination style: PC Pin
• Contact material: Beryllium Copper
• Contact finish: Gold
• Operating temperature range: -40°C ~ 85°C minimum

The C&K SD02H0B meets all mandatory substitution criteria. While it exhibits differences in actuator level (flush/recessed versus raised), height above board, washability, and mechanical/electrical life specifications, these variations do not prevent functional equivalence in applications designed for the 210-2ESF.

Parameter Comparison

Engineering Selection Recommendations

Both the 210-2ESF and SD02H0B are active-status components with ROHS3 compliance and unlimited moisture sensitivity ratings. The SD02H0B provides a higher voltage rating (25VDC versus 20VDC) and extended electrical life (2,000 cycles versus 1,000 cycles), making it suitable for applications where the 210-2ESF is specified. The lower profile of the SD02H0B (0.178" versus 0.204") may present a mechanical consideration in space-constrained PCB layouts. Both components maintain identical pitch, termination, and contact specifications required for direct functional substitution.

Frequently Asked Questions (FAQ)

Q: Can the SD02H0B replace the 210-2ESF in existing designs? A: Yes. Both components share identical circuit configuration (SPST), position count (2), current rating (100mA), pitch (0.100"), contact material and finish, and operating temperature range. The SD02H0B's higher voltage rating (25VDC) and extended electrical life provide equivalent or superior performance in applications designed for the 210-2ESF.

Q: What are the physical differences between these parts? A: The SD02H0B has a lower profile (0.178" versus 0.204" above board) and features a flush/recessed actuator level compared to the raised actuator of the 210-2ESF. These differences may affect PCB layout and user interface considerations but do not impact electrical functionality.

Q: Are both parts RoHS compliant? A: Yes. Both the 210-2ESF and SD02H0B are ROHS3 compliant with unlimited moisture sensitivity ratings (MSL 1).

Q: What is the pitch specification and why does it matter? A: Both components feature a 0.100" (2.54mm) pitch, which defines the spacing between PC pin terminals. Matching pitch ensures proper PCB footprint compatibility and eliminates the need for layout redesign.

Q: How do the electrical life ratings differ? A: The 210-2ESF is rated for 1,000 electrical cycles, while the SD02H0B is rated for 2,000 cycles. The SD02H0B provides extended operational life in applications with frequent switching requirements.
