Key Parameters

Substitute Part Grouping Explanation

The MMS-103-02-L-SV-K-TR qualifies as a direct substitute based on the following critical parameters that remain identical:

• Connector type: Receptacle
• Number of positions: 3
• Pitch - mating: 0.079" (2.00mm)
• Mounting type: Surface Mount
• Contact finish - mating: Gold
• Current rating: 3.9A per Contact
• Operating temperature: -55°C ~ 125°C
• Insulation material: Liquid Crystal Polymer (LCP)
• Contact material: Phosphor Bronze
• RoHS status: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)
• Base product number: MMS-103

The substitute part differs only in the inclusion of pick-and-place features and REACH status documentation, which do not affect electrical or mechanical compatibility.
