Substitute Part Grouping Explanation

The SDA12H0SBR qualifies as a direct substitute for the SDA12H0SBD based on identical electrical and mechanical parameters: both components share the same base product number (SDA12H), circuit configuration (SPST), position count (12), current rating (25mA), voltage rating (24VDC), actuator type (Slide Standard), mounting type (Surface Mount), contact material (Beryllium Copper), contact finish (Gold), and operating temperature range (-40°C to 85°C).

The substitution is valid across the following critical parameters:

• Electrical specifications (voltage, current, circuit type)
• Mechanical dimensions (height, pitch, length)
• Contact properties (material, finish)
• Environmental ratings (temperature range, RoHS compliance)

The primary difference between these parts is packaging format: SDA12H0SBD is supplied in Tube packaging, while SDA12H0SBR is supplied in Tape & Reel (TR) format with tape seal feature.

Parameter Comparison

Engineering Selection Recommendations

Both SDA12H0SBD and SDA12H0SBR are Active status products with identical RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on procurement and assembly requirements:

SDA12H0SBD (Tube packaging) is suitable for applications requiring smaller order quantities or manual assembly processes.

SDA12H0SBR (Tape & Reel packaging with tape seal) is suitable for high-volume automated assembly operations and provides enhanced moisture protection during storage and transport.

Both parts meet the same electrical and mechanical requirements for 24VDC, 25mA SPST switching applications with 12-position configuration.

Frequently Asked Questions (FAQ)

Q: Can SDA12H0SBR replace SDA12H0SBD in production?

A: Yes. Both parts are electrically and mechanically identical. The substitution is valid for any application using the SDA12H0SBD. The difference is packaging format only.

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

A: Tube packaging supplies individual components in a plastic tube, suitable for lower-volume orders and manual assembly. Tape & Reel packaging supplies components on a continuous tape reel, optimized for automated pick-and-place assembly equipment.

Q: Does the tape seal feature on SDA12H0SBR affect component performance?

A: No. The tape seal is a packaging feature that provides additional moisture protection during storage and transport. It does not alter the electrical or mechanical characteristics of the switch.

Q: Are there any PCB layout or footprint differences between these parts?

A: No. Both parts have identical mounting dimensions, pitch (0.100"), height above board (0.175"), and termination style (Gull Wing). PCB footprints are interchangeable.

Q: Which part should be selected for new designs?

A: Selection depends on manufacturing volume and assembly capability. For automated assembly, SDA12H0SBR is preferred. For manual assembly or prototyping, SDA12H0SBD is appropriate. Both are Active status products suitable for new designs.
