SDS004 Equivalent & Substitute Parts

Part Overview

The SDS004 is an active SPST-NO (Single Pole Single Throw - Normally Open) surface mount detection switch manufactured by C&K. It is designed for applications requiring 100mA DC switching at 12V with an overtravel plunger actuator and right-angle mounting configuration. The part is ROHS3 compliant and rated for 50,000 electrical and mechanical cycles. Finding equivalent substitute parts is necessary to address packaging format requirements, inventory availability, and supply chain flexibility while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

The SDS004R is a direct electrical and mechanical equivalent to the SDS004. Both parts share identical specifications across all critical substitution parameters: circuit configuration (SPST-NO), current rating (100mA DC), voltage rating (12V), actuator type (overtravel plunger), mounting configuration (surface mount, right angle), termination style (SMD tab), operating force (75gf), overtravel distance (2.0mm), temperature range (-40°C to 85°C), cycle ratings (50,000 electrical and mechanical), and compliance certifications (ROHS3, REACH unaffected). The sole difference between these parts is packaging format: SDS004 is supplied in Tray packaging, while SDS004R is supplied in Tape & Reel (TR) format. This distinction allows selection based on manufacturing process requirements and inventory management preferences without compromising functional performance.

Parameter Comparison

Engineering Selection Recommendations

Both SDS004 and SDS004R are active products with identical electrical performance, mechanical specifications, and regulatory compliance. Selection between these parts should be based on packaging requirements and supply chain logistics. The SDS004 in Tray packaging is suitable for lower-volume applications and manual assembly processes. The SDS004R in Tape & Reel format is optimized for automated pick-and-place assembly and high-volume production environments. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment across all applications. Inventory availability may also influence selection, as the SDS004R currently has higher stock levels (61,094 units) compared to the SDS004 (2,837 units).

Frequently Asked Questions (FAQ)

Q: Can SDS004R be used as a direct replacement for SDS004 in PCB assembly?

A: Yes. The SDS004R is a direct functional equivalent with identical electrical and mechanical specifications. The only difference is packaging format (Tape & Reel versus Tray). If your assembly process supports Tape & Reel input, the SDS004R is fully compatible.

Q: What is the difference between Tray and Tape & Reel packaging?

A: Tray packaging is used for manual handling and lower-volume assembly. Tape & Reel packaging is designed for automated pick-and-place equipment and high-volume production. Both contain the same component with identical performance.

Q: Are there any electrical performance differences between SDS004 and SDS004R?

A: No. Both parts have identical electrical ratings (100mA at 12V DC), mechanical characteristics (75gf operating force, 2.0mm overtravel), temperature range (-40°C to 85°C), and cycle life (50,000 cycles). They are functionally interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SDS004 and SDS004R are ROHS3 compliant and REACH unaffected. They carry identical regulatory certifications and are suitable for the same applications.

Q: Which part should I select for automated assembly?

A: The SDS004R in Tape & Reel format is the standard choice for automated pick-and-place assembly. Tape & Reel packaging is optimized for feeder compatibility and high-speed production lines.

Q: Can I mix SDS004 and SDS004R in the same production run?

A: Yes, provided your assembly process can handle both packaging formats. However, using a single part number simplifies logistics and reduces handling complexity.
