Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PRA.M0.5GL.LC39N is determined by the following critical parameters:

• Connector Type & Position Count: Receptacle, female sockets, 5-position configuration
• Termination Method: Solder cup termination for PCB integration
• Fastening Mechanism: Push-pull detent lock for secure mating
• Contact Finish: Gold-plated mating surfaces for corrosion resistance
• Ingress Protection: IP50 dust protection rating
• Shell Material: Polysulfone (PSU) construction
• Insert Material: Polyetheretherketone (PEEK)
• Mounting Type: Free hanging (in-line) configuration
• Cable Opening Tolerance: 0.106" ~ 0.154" (2.70mm ~ 3.90mm)

The identified substitute part maintains compatibility across these core parameters, enabling direct functional replacement in equivalent applications.

Parameter Comparison

Engineering Selection Recommendations

Both the PRA.M0.5GL.LC39N and K11MA7-P05LJG0-3980 are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial, medical, and automotive applications.

The K11MA7-P05LJG0-3980 (ODU MEDI-SNAP®) offers a higher current rating of 7.5A compared to the 7A rating of the LEMO part, providing additional margin for power delivery applications. However, the LEMO part supports an extended operating temperature range of -50°C to 150°C, compared to -50°C to 120°C for the ODU substitute. Selection between these parts should be based on specific application requirements regarding current capacity and thermal operating conditions.

Both parts maintain identical mechanical compatibility, including cable opening tolerances, mounting configuration, and connector geometry. Inventory availability is comparable, with 1123 units of the LEMO part and 1083 units of the ODU part currently in stock.
