PRA.M0.4GL.LC39N Equivalent & Substitute Parts

Part Overview

The PRA.M0.4GL.LC39N is a 4-position circular connector receptacle manufactured by LEMO, featuring female sockets with solder cup termination and gold-plated contacts. This connector is designed for applications requiring reliable push-pull detent lock fastening in automotive, industrial, medical, and testing equipment environments. The part is currently active in production with 1,082 units in stock. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit equivalent connector specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PRA.M0.4GL.LC39N are identified based on strict equivalence of the following critical parameters:

• Connector Type: Receptacle with female sockets
• Number of Positions: 4-position configuration
• Termination Method: Solder cup
• Fastening Mechanism: Push-pull detent lock
• Contact Finish: Gold-plated mating surfaces
• Shell Material: Polysulfone (PSU)
• Insert Material: Polyetheretherketone (PEEK)
• Ingress Protection: IP50 dust protection
• Mounting Style: Free hanging (in-line)
• Cable Opening Range: 0.106" ~ 0.154" (2.70mm ~ 3.90mm)

The substitute part K11MA7-P04LJG0-3980 from ODU meets all critical substitution criteria. Variations in current rating (10A vs. 8A) and maximum operating temperature (-50°C ~ 120°C vs. -50°C ~ 150°C) represent enhanced or equivalent performance characteristics that do not prevent substitution in applications designed for the primary part.

Parameter Comparison

Engineering Selection Recommendations

Both the PRA.M0.4GL.LC39N and K11MA7-P04LJG0-3980 are active production parts with ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications in medical, industrial, and automotive sectors. The ODU substitute part provides equivalent mechanical and electrical performance with a higher current rating (10A vs. 8A), which represents a performance advantage in applications where current capacity is a design consideration. The operating temperature range of the LEMO part extends to 150°C compared to 120°C for the ODU part; applications requiring operation above 120°C must use the primary LEMO part. Both connectors maintain identical cable opening specifications and ingress protection ratings, ensuring mechanical compatibility in existing designs.

Frequently Asked Questions (FAQ)

Q: Can K11MA7-P04LJG0-3980 be used as a direct replacement for PRA.M0.4GL.LC39N?

A: Yes, for applications operating within the temperature range of -50°C to 120°C and requiring 10A or less current capacity. Both parts share identical connector type, position count, termination method, fastening mechanism, contact finish, shell material, insert material, cable opening range, and ingress protection rating.

Q: What is the difference in current rating between these parts?

A: The LEMO PRA.M0.4GL.LC39N is rated for 8A, while the ODU K11MA7-P04LJG0-3980 is rated for 10A. The ODU part provides higher current capacity and can be used in applications designed for the LEMO part without current-related limitations.

Q: Are there temperature limitations when substituting?

A: Yes. The LEMO part operates from -50°C to 150°C, while the ODU part operates from -50°C to 120°C. Applications requiring operation above 120°C must use the LEMO PRA.M0.4GL.LC39N.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry the same ECCN (EAR99) and HTSUS (8536.69.4020) classifications.

Q: What packaging options are available?

A: The LEMO PRA.M0.4GL.LC39N is supplied in standard packaging, while the ODU K11MA7-P04LJG0-3980 is supplied in bulk packaging.

Q: Are the shell sizes equivalent between these parts?

A: The LEMO part uses shell size M04, while the ODU part uses shell size 1. Both accommodate the same cable opening range (0.106" ~ 0.154" / 2.70mm ~ 3.90mm) and are mechanically compatible in applications designed for 4-position circular connectors with solder cup termination.
