Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PRA.M0.2GL.LC52J is determined by the following critical parameters:

• Connector Type & Position Count: Receptacle, Female Sockets with 2 positions
• Termination Method: Solder Cup
• Fastening Mechanism: Push-Pull, Detent Lock
• Shell Material: Polysulfone (PSU)
• Contact Finish: Gold plating on mating surfaces
• Cable Opening Range: 0.157" ~ 0.205" (4.00mm ~ 5.20mm)
• Ingress Protection: IP50 - Dust Protected
• Mounting Configuration: Free Hanging (In-Line)
• Compliance: ROHS3 Compliant, REACH Unaffected

The substitute part K11MA7-P02LPH0-5240 (ODU MEDI-SNAP®) meets these core substitution criteria. Variations in current rating (14A vs. 10A) and maximum operating temperature (-50°C ~ 120°C vs. -50°C ~ 150°C) represent parameter differences that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the PRA.M0.2GL.LC52J and K11MA7-P02LPH0-5240 are active production parts with ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications in medical, industrial, and automotive sectors.

Selection between these parts must account for the following parameter differences:

• Current Rating: The ODU substitute supports 14A versus the LEMO part's 10A rating. Applications requiring currents between 10A and 14A may utilize the substitute; applications limited to 10A or below are compatible with either part.
• Operating Temperature: The LEMO part operates to 150°C maximum, while the ODU part operates to 120°C maximum. Applications requiring operation above 120°C require the LEMO PRA.M0.2GL.LC52J.
• Shell Size Designation: The LEMO part uses M02 designation; the ODU part uses size 1 designation. These represent equivalent physical dimensions within their respective manufacturer standards.

Both parts share identical mechanical mounting, termination method, fastening mechanism, and ingress protection rating, supporting direct substitution in applications where the parameter differences do not impose constraints.

Frequently Asked Questions (FAQ)

Q: Can K11MA7-P02LPH0-5240 replace PRA.M0.2GL.LC52J in all applications?

A: Substitution is valid when application requirements do not exceed 120°C operating temperature and do not require current ratings below 10A. Applications operating above 120°C or with specific current limitations below 10A require the original LEMO part.

Q: What is the significance of the shell size difference (M02 vs. 1)?

A: M02 and size 1 represent equivalent physical dimensions within LEMO and ODU manufacturer standards respectively. Both connectors accept the same cable opening range (4.00mm ~ 5.20mm) and share identical mechanical interfaces.

Q: Are both parts suitable for medical applications?

A: Both parts list medical applications in their specifications and maintain ROHS3 compliance and REACH unaffected status. Medical application suitability must be confirmed against specific device requirements and regulatory pathways.

Q: What is the difference in contact material between these parts?

A: The LEMO part does not specify contact material in the provided data. The ODU part specifies brass contact material. Both parts feature gold plating on mating surfaces for electrical contact.

Q: Can these connectors be used interchangeably in existing designs?

A: Mechanical and electrical interfaces are compatible. Design validation must confirm that the operating temperature range and current rating of the selected part align with application specifications.
