KAE02SGGT DIP Switch Equivalent & Substitute Parts

Part Overview

The KAE02SGGT is a surface mount DIP switch manufactured by E-Switch, classified as a SPST (Single Pole Single Throw) slide actuator switch. This component is designed for low-current switching applications at 24VDC with a 25mA current rating. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to provide design flexibility, supply chain alternatives, and packaging options while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KAE02SGGT is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: Must be SPST
• Number of Positions: Must be 2
• Current Rating: Must be 25mA
• Voltage Rating: Must be 24VDC
• Actuator Type: Must be Slide (Standard)
• Actuator Level: Must be Flush, Recessed
• Contact Finish: Must be Gold
• Mounting Type: Must be Surface Mount
• Termination Style: Must be Gull Wing
• Pitch: Must be 0.100" (2.54mm)
• Operating Temperature Range: Must be -20°C to 85°C
• Mechanical Life: Must be 2,000 Cycles
• Electrical Life: Must be 2,000 Cycles
• RoHS Status: Must be ROHS3 Compliant
• MSL Rating: Must be 1 (Unlimited)

The substitute parts DMR02T and DMR02TTR, both manufactured by APEM Inc., meet all critical electrical and mechanical parameters. These parts differ only in packaging format (Tube versus Tape & Reel) and minor dimensional variations within acceptable tolerances. Both are functionally equivalent for direct replacement in applications requiring the KAE02SGGT specification.

Parameter Comparison

Engineering Selection Recommendations

Both DMR02T and DMR02TTR are direct functional equivalents to the KAE02SGGT. Selection between these alternatives should be based on procurement and assembly requirements:

DMR02T (Tube Packaging): Suitable for applications requiring standard tube packaging format. Maintains identical electrical and mechanical specifications to the KAE02SGGT.

DMR02TTR (Tape & Reel Packaging): Appropriate for high-volume automated assembly operations where tape and reel format provides handling and placement efficiency. Electrical and mechanical performance is identical to the tube-packaged variant.

All three parts maintain ROHS3 compliance, unlimited MSL rating, and REACH unaffected status, ensuring regulatory compatibility across applications. The minor dimensional variations (height and length) fall within standard manufacturing tolerances and do not affect functional interchangeability in standard PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can DMR02T and DMR02TTR be used interchangeably with KAE02SGGT?

A: Yes. Both APEM Inc. parts meet all critical electrical and mechanical parameters required for direct substitution. The only difference is packaging format (Tube versus Tape & Reel), which does not affect component performance or PCB compatibility.

Q: What is the difference between DMR02T and DMR02TTR?

A: Both parts are electrically and mechanically identical. DMR02T is supplied in Tube packaging, while DMR02TTR is supplied in Tape & Reel (TR) format. Selection depends on assembly process requirements and volume considerations.

Q: Are there dimensional compatibility concerns when substituting these parts?

A: The height above board differs by 0.002" (0.05mm) and length differs by 0.004" (0.10mm) between the KAE02SGGT and APEM equivalents. These variations are within standard manufacturing tolerances and do not affect standard PCB layout or assembly processes.

Q: Do all three parts meet the same regulatory requirements?

A: Yes. KAE02SGGT, DMR02T, and DMR02TTR are all ROHS3 compliant, carry MSL 1 (Unlimited) rating, and are REACH unaffected. They are suitable for equivalent regulatory compliance in applications requiring these certifications.

Q: What is the contact material difference between the main part and substitutes?

A: The KAE02SGGT uses Copper contacts, while DMR02T and DMR02TTR use Copper Alloy contacts. Both materials provide equivalent gold-plated contact finish and electrical performance for the specified 25mA, 24VDC application.

Q: Which part should be selected for high-volume production?

A: DMR02TTR (Tape & Reel format) is optimized for high-volume automated assembly. DMR02T (Tube format) is suitable for lower-volume or manual assembly processes. Both provide identical electrical performance.
