Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PRA.M0.4GL.LC52R are identified based on strict equivalence across the following critical parameters:

• Connector type: Receptacle with female sockets
• Number of positions: 4
• Termination method: Solder cup
• Fastening mechanism: Push-pull detent lock
• Shell material: Polysulfone (PSU)
• Contact finish: Gold plating
• Mounting configuration: Free hanging (in-line)
• Ingress protection: IP50 dust protection
• Insert material: Polyetheretherketone (PEEK)
• Cable opening range: 0.157" ~ 0.205" (4.00mm ~ 5.20mm)

The substitute part K11MA7-P04LJG0-5220 from ODU meets these core functional and mechanical requirements, enabling direct substitution in applications where the LEMO part is unavailable.

Parameter Comparison

Engineering Selection Recommendations

Both the PRA.M0.4GL.LC52R and K11MA7-P04LJG0-5220 are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial, medical, and automotive applications.

The ODU K11MA7-P04LJG0-5220 substitute provides a higher current rating of 10A compared to the LEMO part's 8A rating, making it suitable for applications requiring increased current capacity. However, the LEMO part supports an extended operating temperature range of -50°C to 150°C, compared to the ODU part's -50°C to 120°C maximum. Selection between these parts should be based on specific application requirements for current handling and temperature exposure.

Both connectors share identical mechanical interfaces, shell materials, contact finishes, and ingress protection ratings, ensuring mechanical and electrical compatibility in equivalent circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the K11MA7-P04LJG0-5220 be used as a direct replacement for the PRA.M0.4GL.LC52R?

A: Yes, the K11MA7-P04LJG0-5220 is mechanically and electrically compatible as a substitute. Both connectors feature identical 4-position solder cup receptacles with push-pull detent lock fastening, gold-plated contacts, and IP50 ingress protection. Compatibility is confirmed across connector type, termination method, shell material, and cable opening specifications.

Q: What are the differences between these two parts?

A: The primary differences are current rating and maximum operating temperature. The LEMO PRA.M0.4GL.LC52R is rated for 8A at temperatures up to 150°C, while the ODU K11MA7-P04LJG0-5220 is rated for 10A at temperatures up to 120°C. Applications requiring sustained operation above 120°C should use the LEMO part. Applications requiring current capacity above 8A should use the ODU part.

Q: Are both parts compliant with current regulatory standards?

A: Yes, both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for industrial, medical, and automotive applications.

Q: What is the cable opening specification, and does it affect substitution?

A: Both parts support identical cable opening ranges of 0.157" to 0.205" (4.00mm to 5.20mm), ensuring compatibility with the same cable assemblies and backshell configurations.

Q: Do these connectors require any special handling or storage considerations?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no special moisture control requirements during storage or handling.
