CTS 210-10MSTFD DIP Switch Equivalent & Substitute Parts

Part Overview

The CTS 210-10MSTFD is an active-status DIP switch module featuring SPST (Single Pole Single Throw) circuit configuration with 10 positions. This through-hole mounted component is rated for 100mA at 20VDC and employs a slide actuator with standard raised profile. The switch utilizes beryllium copper contacts with gold finish and is sealed with epoxy-coated terminals. This component is essential for applications requiring manual configuration switching in industrial control, telecommunications, and consumer electronics where space-constrained PCB layouts demand compact, reliable switching solutions. Equivalent alternatives are identified to support supply chain flexibility and design optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CTS 210-10MSTFD is determined by strict alignment of the following critical parameters:

Circuit configuration must remain SPST to maintain functional equivalence in single-pole switching applications. The 10-position count is mandatory for configuration flexibility in target applications. Through-hole mounting type and 0.100" (2.54mm) pitch are required for PCB footprint compatibility. Gold-plated contacts ensure equivalent electrical performance and corrosion resistance. Operating temperature range must encompass or match the -40°C to 85°C specification. RoHS3 compliance and active product status ensure regulatory alignment and supply continuity.

The identified substitute part 1-1825002-7 (TE Connectivity ALCOSWITCH) meets these core substitution criteria while presenting trade-offs in current and voltage ratings that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the CTS 210-10MSTFD and TE Connectivity 1-1825002-7 maintain active product status and ROHS3 compliance, supporting long-term supply availability and regulatory conformance. Selection between these components must account for application-specific current and voltage requirements. The CTS part supports 100mA operation at 20VDC, while the TE Connectivity substitute is rated for 25mA at 24VDC. Applications requiring the full 100mA current capacity must retain the CTS 210-10MSTFD. Lower-current applications operating at or below 25mA may utilize the TE Connectivity alternative. The TE part features a flush, recessed actuator profile compared to the raised profile of the CTS component, affecting PCB assembly clearance and operator accessibility. Both components share identical electrical life specifications (1,000 cycles) and moisture sensitivity ratings (MSL 1). The CTS part supports extended low-temperature operation to -40°C, while the TE substitute operates to -30°C minimum.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-1825002-7 directly replace the CTS 210-10MSTFD in all applications?

A: Direct replacement is limited to applications where current demand does not exceed 25mA. The TE part is rated for 25mA maximum versus the CTS part's 100mA rating. Voltage compatibility is maintained (24VDC TE rating exceeds the 20VDC CTS specification). Mechanical fit is compatible due to matching pitch (0.100"), through-hole mounting, and nearly identical height above board (0.189" vs. 0.190").

Q: What is the significance of the actuator level difference (raised vs. flush/recessed)?

A: Actuator level affects physical accessibility and PCB assembly clearance. The CTS raised profile provides greater tactile feedback and easier manual operation. The TE flush, recessed profile occupies less vertical space above the PCB, beneficial in space-constrained enclosures. This difference does not affect electrical function but may impact user interface design and assembly procedures.

Q: Are both parts suitable for low-temperature applications?

A: The CTS 210-10MSTFD supports operation to -40°C, while the TE Connectivity 1-1825002-7 operates to -30°C minimum. Applications requiring -40°C operation must use the CTS component. Applications limited to -30°C or higher may use either part.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both carry MSL 1 (Unlimited) moisture sensitivity ratings, indicating no special storage or handling requirements.

Q: What is the basis for substitution between these two DIP switch models?

A: Substitution is based on matching SPST circuit configuration, 10-position count, through-hole mounting, 0.100" pitch, gold-plated contacts, and active product status. The primary trade-off is current rating (100mA vs. 25mA), which must be evaluated against specific application load requirements.
