CTS Electrocomponents 210-2LPSFD DIP Switch Equivalent & Substitute Parts

Part Overview

The CTS Electrocomponents 210-2LPSFD 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 and gold-plated beryllium copper contacts. The part is sealed with epoxy-coated terminals and rated for 1,000 electrical cycles across an operating temperature range of -40°C to 85°C. Equivalent substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity for applications where the original specification can accommodate minor parameter variations within acceptable electrical and mechanical tolerances.

Key Parameters

Substitute Part Grouping Explanation

The C&K SD02H0B qualifies as an equivalent substitute for the CTS 210-2LPSFD based on the following critical parameters:

Matching Parameters (Substitution Basis):

• Circuit configuration: SPST
• Number of positions: 2
• Current rating: 100mA
• Actuator type: Slide (Standard)
• Actuator level: Flush, Recessed
• Contact material: Beryllium Copper
• Contact finish: Gold
• Mounting type: Through Hole
• Termination style: PC Pin
• Pitch: 0.100" (2.54mm)
• Operating temperature range: -40°C to 85°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)
• Product status: Active

Allowable Parameter Variations:

• Voltage rating: 20VDC (main part) vs. 25VDC (substitute) — the substitute supports higher voltage operation, maintaining backward compatibility
• Electrical life: 1,000 cycles (main part) vs. 2,000 cycles (substitute) — the substitute exceeds cycle life requirements
• Mechanical life: Not specified (main part) vs. 2,000 cycles (substitute) — additional specification in substitute
• Height above board: 0.180" (4.57mm) vs. 0.178" (4.52mm) — negligible dimensional difference within PCB layout tolerance
• Washable: No (main part) vs. Yes (substitute) — substitute offers enhanced cleaning capability
• Features: Epoxy sealed terminals (main part) vs. Tape seal (substitute) — both provide terminal protection

Parameter Comparison

Engineering Selection Recommendations

Both the CTS 210-2LPSFD and C&K SD02H0B are active-status products with full ROHS3 compliance and unlimited moisture sensitivity rating, making them suitable for current production and long-term supply chain planning. The C&K SD02H0B provides enhanced electrical cycle life (2,000 cycles versus 1,000 cycles) and higher voltage rating (25VDC versus 20VDC), offering improved performance margins for applications operating within the 20VDC specification. The dimensional difference in height above board (0.02mm) is negligible for standard PCB layout applications. Both parts maintain identical circuit configuration, current handling, actuator characteristics, and contact metallurgy, ensuring functional and mechanical interchangeability within the specified operating parameters.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical SPST circuit configuration, 100mA current rating, slide actuator type, flush/recessed positioning, beryllium copper gold-plated contacts, through-hole mounting, PC pin termination, and 2.54mm pitch. The operating temperature range and compliance certifications are identical. The C&K part supports higher voltage (25VDC) and extended electrical cycle life (2,000 cycles), making it functionally compatible with applications designed for the CTS part.

Q: What is the significance of the voltage rating difference (20VDC vs. 25VDC)?

A: The C&K SD02H0B is rated for 25VDC operation, which exceeds the CTS 210-2LPSFD specification of 20VDC. This higher rating provides additional voltage margin and does not restrict use in applications operating at or below 20VDC. The substitute part maintains full compatibility with the original design voltage specification.

Q: How do the electrical cycle life ratings affect component selection?

A: The CTS part is rated for 1,000 electrical cycles, while the C&K substitute is rated for 2,000 cycles. For applications requiring extended operational life or frequent switching, the C&K part offers doubled cycle life capacity. Both parts meet the specified cycle requirements for standard DIP switch applications.

Q: Are there any dimensional considerations for PCB layout?

A: The height above board differs by 0.02mm (0.180" versus 0.178"), which is within standard PCB layout tolerance and does not require design modification. Both parts maintain identical pitch (2.54mm) and mounting footprint compatibility.

Q: Do both parts support the same environmental and compliance requirements?

A: Yes. Both the CTS 210-2LPSFD and C&K SD02H0B are ROHS3 compliant, REACH unaffected, rated for -40°C to 85°C operation, and carry unlimited moisture sensitivity level (MSL 1). Both parts are active-status products suitable for current production applications.

Q: What is the difference between epoxy sealed terminals and tape seal?

A: Both sealing methods provide terminal protection. The CTS part uses epoxy sealed terminals, while the C&K substitute uses tape seal. The C&K part additionally supports washable processing, offering enhanced cleaning capability for manufacturing environments requiring post-assembly cleaning procedures.
