SDS002 SPST-NC Surface Mount Detection Switch Equivalent & Substitute Parts

Part Overview

The SDS002 is an active SPST-NC (Single Pole Single Throw - Normally Closed) surface mount detection switch manufactured by C&K. This component operates at 12V DC with a 100mA current rating and features an overtravel plunger actuator in a right-angle configuration. The switch is designed for applications requiring momentary contact operation with a 75gf operating force and supports 50,000 electrical and mechanical cycles. The SDS002 is actively produced and maintains full RoHS3 and REACH compliance, making it suitable for modern electronic assemblies requiring environmental standards adherence.

Substitute parts are identified when packaging configurations differ while maintaining identical electrical performance and mechanical specifications, enabling procurement flexibility across supply chain variations.

Substitute Part Grouping Explanation

The SDS002R qualifies as a direct substitute for the SDS002 based on identical electrical and mechanical specifications. Both parts share the same circuit configuration (SPST-NC), switch function (On-Mom), current rating (100mA DC), voltage rating (12V DC), actuator type (Overtravel Plunger), mounting configuration (Surface Mount, Right Angle), termination style (SMD Tab), operating force (75gf), overtravel distance (0.079"/2.0mm), temperature range (-40°C to 85°C), cycle life ratings (50,000 cycles electrical and mechanical), and compliance certifications (ROHS3, REACH Unaffected, MSL 1).

The sole difference between these parts is packaging format: SDS002 is supplied in Bulk packaging, while SDS002R is supplied in Tape & Reel (TR) format. This distinction affects procurement, storage, and automated assembly processes but does not alter component functionality or performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both SDS002 and SDS002R are active products from C&K with identical electrical and mechanical specifications. Selection between these parts should be based on assembly and procurement requirements:

SDS002 (Bulk packaging) is appropriate for manual assembly operations, prototyping, and applications where component quantities are managed through discrete handling. This format supports flexible inventory management and lower initial procurement commitments.

SDS002R (Tape & Reel packaging) is designed for automated pick-and-place assembly processes and high-volume production environments. This format optimizes feeder compatibility with standard SMT equipment and reduces handling labor in manufacturing operations.

Both parts maintain full compliance with ROHS3 and REACH regulations, ensuring suitability for applications subject to environmental standards. The MSL 1 rating indicates unlimited shelf life under standard storage conditions, eliminating moisture-related procurement constraints.

Frequently Asked Questions (FAQ)

Q: Can SDS002 and SDS002R be used interchangeably in circuit design?

A: Yes. Both parts are electrically and mechanically identical. They perform the same function in SPST-NC momentary switch applications at 12V DC with 100mA current capacity. The only difference is packaging format, which does not affect component performance or circuit behavior.

Q: What is the primary reason to choose SDS002R over SDS002?

A: SDS002R in Tape & Reel format is optimized for automated SMT assembly lines. If your manufacturing process uses pick-and-place equipment, SDS002R provides better feeder compatibility and reduces manual handling. SDS002 in Bulk format is better suited for manual assembly or lower-volume production.

Q: Are there any compliance or certification differences between these parts?

A: No. Both SDS002 and SDS002R carry identical certifications: ROHS3 Compliant, REACH Unaffected, and MSL 1 (Unlimited). There are no environmental, regulatory, or quality differences between the two part numbers.

Q: Can I substitute SDS002R for SDS002 in an existing design?

A: Yes, without design changes. The electrical and mechanical specifications are identical. If your assembly process supports Tape & Reel format, SDS002R is a direct substitute. If your process requires Bulk packaging, SDS002 remains the appropriate choice.

Q: What does MSL 1 (Unlimited) mean for storage and handling?

A: MSL 1 indicates the component has unlimited shelf life under standard storage conditions (typically 23°C, 50% relative humidity). No special moisture-control packaging or baking procedures are required before assembly, regardless of storage duration.

Q: Are both parts currently in production?

A: Yes. Both SDS002 and SDS002R are active products from C&K with current inventory availability. Both maintain the same product status and supply chain support.
