SDA12H0SB Equivalent & Substitute Parts

Part Overview

The SDA12H0SB is a 12-position DIP switch manufactured by C&K, designed for surface mount applications requiring SPST (Single Pole Single Throw) switching functionality. This component operates at 24VDC with a 25mA current rating and features a slide actuator with standard positioning. The part is Active in product status and widely used in industrial control, telecommunications, and embedded systems where configuration switching is required.

Alternative models become necessary when specific packaging requirements differ from the original specification, such as when tape and reel packaging is preferred for automated assembly processes, or when inventory constraints require sourcing from available stock configurations.

Substitute Part Grouping Explanation

The SDA12H0SB and its substitute SDA12H0SBR share identical electrical and mechanical specifications, differing only in packaging format. Both parts maintain the same base product number (SDA12H) and are manufactured by C&K with Active product status.

Substitution is valid based on the following matching parameters:

• Circuit configuration: SPST
• Number of positions: 12
• Current and voltage ratings: 25mA at 24VDC
• Actuator type and level: Slide (Standard), Flush/Recessed
• Contact material and finish: Beryllium Copper with Gold plating
• Mounting and termination: Surface Mount with Gull Wing termination
• Pitch and height specifications: 0.100" (2.54mm) pitch, 0.175" (4.45mm) height
• Operating temperature range: -40°C ~ 85°C
• Compliance certifications: ROHS3 Compliant, REACH Unaffected, MSL 1

The only distinction is packaging: SDA12H0SB is supplied in Tube packaging, while SDA12H0SBR is supplied in Tape & Reel (TR) format.

Parameter Comparison

Engineering Selection Recommendations

Both SDA12H0SB and SDA12H0SBR are Active products from C&K with identical electrical performance and mechanical specifications. Selection between these parts should be based on assembly process requirements and inventory availability.

The SDA12H0SB in Tube packaging is suitable for manual assembly, prototyping, and low-volume production runs. The SDA12H0SBR in Tape & Reel format is optimized for automated pick-and-place assembly systems and high-volume manufacturing environments.

Both parts maintain full compliance with ROHS3 and REACH requirements, with MSL 1 rating indicating no moisture sensitivity constraints during storage and handling. The identical mechanical life (1,000 cycles) and electrical life (1,000 cycles) specifications ensure equivalent reliability in field applications.

Frequently Asked Questions (FAQ)

Q: Can SDA12H0SBR be used as a direct replacement for SDA12H0SB in circuit design?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format. Circuit performance, switching characteristics, and reliability are equivalent.

Q: What is the primary reason to choose SDA12H0SBR over SDA12H0SB?

A: SDA12H0SBR in Tape & Reel packaging is designed for automated assembly processes. If your manufacturing process uses pick-and-place equipment, SDA12H0SBR is the appropriate choice. For manual assembly or prototyping, SDA12H0SB in Tube packaging is standard.

Q: Are there any storage or handling differences between Tube and Tape & Reel packaging?

A: Both parts have MSL 1 rating, indicating unlimited shelf life without moisture sensitivity concerns. Storage and handling procedures are equivalent for both packaging formats.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SDA12H0SB and SDA12H0SBR are ROHS3 Compliant and REACH Unaffected, with identical environmental and regulatory certifications.

Q: What is the mechanical life specification for these DIP switches?

A: Both parts are rated for 1,000 mechanical cycles and 1,000 electrical cycles, representing the actuator engagement and electrical switching durability under specified operating conditions.

Q: Can these parts be used in applications outside the -40°C to 85°C temperature range?

A: No. Both parts are specified for operation within -40°C to 85°C. Applications requiring extended temperature ranges require alternative component selection.
