SDS005 SPST-NC Surface Mount Detection Switch Equivalent & Substitute Parts

Part Overview

The C&K SDS005 is an active SPST-NC (Single Pole Single Throw, Normally Closed) surface mount detection switch rated for 100mA DC at 12V. This component features an overtravel plunger actuator with right-angle mounting configuration and SMD tab termination. The SDS005 is designed for applications requiring momentary contact switching with reliable electrical and mechanical performance across industrial temperature ranges.

The SDS005 remains in active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified based on identical electrical specifications, mechanical compatibility, and functional equivalence to ensure seamless integration in existing designs.

Substitute Part Grouping Explanation

Substitute parts for the SDS005 are qualified based on strict equivalence across all critical electrical and mechanical parameters. The substitution criteria are:

• Identical circuit configuration (SPST-NC)
• Identical switch function (On-Mom momentary operation)
• Identical current rating (100mA DC)
• Identical voltage rating (12V DC)
• Identical actuator type (Overtravel Plunger)
• Identical mounting configuration (Surface Mount, Right Angle)
• Identical termination style (SMD Tab)
• Identical operating force (75gf)
• Identical overtravel specification (0.079" / 2.0mm)
• Identical temperature operating range (-40°C to 85°C)
• Identical electrical and mechanical life ratings (50,000 cycles)
• Identical compliance certifications (ROHS3, REACH Unaffected)

The only permitted variation is packaging format (Tray versus Tape & Reel), which does not affect functional or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the SDS005 and SDS005R are active products with identical electrical specifications, mechanical characteristics, and compliance certifications. Selection between these parts is determined solely by packaging and supply chain requirements:

• SDS005 (Tray packaging) is suitable for manual assembly, prototyping, and lower-volume production environments where individual component handling is standard practice.
• SDS005R (Tape & Reel packaging) is optimized for automated pick-and-place assembly and high-volume manufacturing operations requiring continuous reel feeding.

Both variants maintain full ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance across all applications. The choice between packaging formats does not impact functional performance, electrical ratings, or mechanical reliability.

Frequently Asked Questions (FAQ)

Q: Can SDS005 and SDS005R be used interchangeably in the same circuit design?

A: Yes. Both parts are electrically and mechanically identical. They differ only in packaging format (Tray versus Tape & Reel). The circuit performance, switching characteristics, and reliability are equivalent.

Q: What is the primary difference between SDS005 and SDS005R?

A: The packaging format. SDS005 is supplied in Tray packaging for manual handling and lower-volume applications. SDS005R is supplied in Tape & Reel format for automated assembly processes and high-volume production.

Q: Are there any compatibility concerns when substituting SDS005 with SDS005R?

A: No compatibility concerns exist. Both parts have identical footprints, termination styles (SMD Tab), mounting configurations (Surface Mount, Right Angle), and electrical specifications. PCB layout and assembly processes remain unchanged.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SDS005 and SDS005R are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: What determines the choice between Tray and Tape & Reel packaging?

A: Manufacturing process requirements. Tape & Reel packaging is required for automated pick-and-place assembly. Tray packaging is used for manual assembly, prototyping, and applications where automated feeding is not necessary.

Q: Are the electrical and mechanical life ratings identical?

A: Yes. Both parts are rated for 50,000 electrical cycles and 50,000 mechanical cycles under identical operating conditions.
