SDS001R Equivalent & Substitute Parts

Part Overview

The SDS001R is an SPST-NO (Single Pole Single Throw - Normally Open) surface mount detection switch manufactured by C&K. This component is designed for applications requiring momentary contact switching with a 100mA DC current rating at 12V. The part is currently active in production and fully compliant with RoHS3 and REACH regulations, making it suitable for modern electronic assemblies requiring environmental compliance.

Substitute parts are identified to provide design flexibility when the primary component is unavailable or when alternative electrical specifications better suit specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

The 900AGQ from E-Switch qualifies as a functional substitute for the SDS001R based on the following critical parameters:

Matching Electrical Specifications:

• Circuit configuration: Both are SPST-NO
• Switch function: Both are Off-Mom (momentary contact)
• Current rating: Both support 100mA DC
• Electrical life: Both rated for 50,000 cycles

Matching Mechanical Specifications:

• Actuator type: Both use overtravel plunger design
• Mounting type: Both are surface mount
• Packaging: Both supplied in Tape & Reel format
• Moisture sensitivity: Both rated MSL 1 (Unlimited)

Compliance Alignment:

• Both are RoHS3 compliant
• Both are REACH unaffected
• Both carry EAR99 ECCN classification

The 900AGQ operates at a higher voltage rating (50V versus 12V) and features different termination (Gull Wing versus SMT Tab) and mounting orientation (standard surface mount versus right angle). These differences do not prevent substitution in applications where the 12V specification is not a hard requirement and PCB layout accommodates the alternative termination style.

Parameter Comparison

Engineering Selection Recommendations

Both the SDS001R and 900AGQ are active production components with full RoHS3 compliance and REACH unaffected status, qualifying them for use in regulated markets and modern electronic assemblies.

The SDS001R is the primary choice when the application circuit operates at 12V DC and requires right-angle surface mount orientation with SMT tab termination. The lower operating temperature minimum (-40°C versus -25°C) provides extended environmental capability for industrial applications.

The 900AGQ serves as a substitute when the application can accommodate standard surface mount orientation with Gull Wing termination and when the circuit voltage specification permits operation at 50V. The lower operating force (50gf versus 75gf) may be advantageous in applications requiring reduced actuation pressure.

Both components share identical electrical life ratings (50,000 cycles) and current handling capacity (100mA DC), ensuring equivalent reliability in momentary contact switching applications.

Frequently Asked Questions (FAQ)

Q: Can the 900AGQ replace the SDS001R in a 12V circuit?

A: The 900AGQ has a 50V voltage rating, which exceeds the 12V requirement. In a 12V circuit, the 900AGQ will function correctly as it is rated for higher voltage operation. However, verify that the PCB layout accommodates the Gull Wing termination style and standard surface mount orientation, as these differ from the SDS001R's SMT Tab and right-angle configuration.

Q: What are the key differences between these two parts?

A: The primary differences are termination style (SMT Tab versus Gull Wing), mounting orientation (right angle versus standard surface mount), voltage rating (12V versus 50V), and operating force (75gf versus 50gf). Both share identical circuit configuration (SPST-NO), current rating (100mA DC), electrical life (50,000 cycles), and compliance certifications.

Q: Are both parts suitable for industrial temperature ranges?

A: The SDS001R operates from -40°C to 85°C, providing broader low-temperature capability. The 900AGQ operates from -25°C to 85°C. For applications requiring operation below -25°C, the SDS001R is the appropriate choice.

Q: Do both parts come in the same packaging format?

A: Yes, both the SDS001R and 900AGQ are supplied in Tape & Reel (TR) packaging, enabling compatibility with automated assembly processes.

Q: Are there any compliance concerns with substitution?

A: Both parts are RoHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification. No compliance barriers exist for substitution in regulated applications.
