DMR02 Equivalent & Substitute Parts

Part Overview

The DMR02 is a surface mount DIP slide switch manufactured by APEM Inc., designed for low-current switching applications at 24VDC. This SPST (Single Pole Single Throw) component features a 2-position slide actuator with a current rating of 25mA and is classified as an active product with full RoHS3 compliance. Equivalent and substitute parts are identified when they maintain identical electrical specifications, mechanical compatibility, and regulatory certifications, enabling seamless integration into existing designs or providing alternative sourcing options.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DMR02 are qualified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

Electrical Parameters (Non-Negotiable):

• Circuit configuration: SPST
• Number of positions: 2
• Current rating: 25mA
• Voltage rating: 24VDC
• Contact finish: Gold

Mechanical Parameters (Non-Negotiable):

• Actuator type: Slide (Standard)
• Actuator level: Flush, Recessed
• Mounting type: Surface Mount
• Termination style: Gull Wing
• Pitch: 0.100" (2.54mm)

Regulatory & Compliance (Non-Negotiable):

• RoHS3 Compliance
• MSL Rating: 1 (Unlimited)
• REACH Status: REACH Unaffected
• ECCN: EAR99

The identified substitutes (KAE02SGGR and KAE02TGGT) from E-Switch meet all critical electrical and mechanical requirements. Variations in packaging format (Tube vs. Tape & Reel) and minor dimensional tolerances do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both KAE02SGGR and KAE02TGGT qualify as functional equivalents to the DMR02 based on identical electrical specifications, mechanical compatibility, and regulatory compliance. Selection between these options depends on packaging and process requirements:

KAE02SGGR (Tape & Reel): Suitable for high-volume automated assembly operations where tape and reel packaging is standard. Provides equivalent electrical and mechanical performance with alternative packaging format.

KAE02TGGT (Tube): Matches the original DMR02 packaging format and includes washable capability with tape seal features. Recommended for applications requiring post-assembly cleaning processes or where tube packaging aligns with existing supply chain procedures.

All three parts maintain identical circuit configuration, current and voltage ratings, actuator specifications, and lifecycle ratings. The minor dimensional variance in height above board (0.002" difference) falls within standard PCB design tolerances and does not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can KAE02SGGR and KAE02TGGT be used interchangeably with DMR02 in the same circuit?

A: Yes. Both E-Switch parts maintain identical electrical specifications (SPST, 25mA, 24VDC), mechanical configuration (slide actuator, gull wing termination, 2.54mm pitch), and operating characteristics. The primary differences are packaging format and washability features, which do not affect electrical function.

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

A: Packaging affects supply chain logistics and assembly processes. Tube packaging (DMR02, KAE02TGGT) is suitable for manual or semi-automated assembly. Tape & Reel packaging (KAE02SGGR) is optimized for high-speed automated pick-and-place equipment. Electrical and mechanical performance are identical.

Q: Does the washable feature of KAE02TGGT affect compatibility?

A: No. The washable feature with tape seal is an additional capability that does not impact electrical or mechanical compatibility. It is beneficial for applications requiring post-assembly cleaning but is not required for standard operation.

Q: Are there dimensional concerns with the 0.002" height difference?

A: No. The height variance (DMR02: 0.146" vs. KAE02 series: 0.148") is within standard PCB design tolerances and does not affect board layout or component clearance in typical applications.

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

A: Yes. DMR02, KAE02SGGR, and KAE02TGGT are all ROHS3 compliant, REACH unaffected, and carry MSL Rating 1 (Unlimited). They share identical ECCN (EAR99) and HTSUS classifications.
