Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PRA.M0.4GL.LC52J is determined by strict alignment of 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 on mating surfaces
• Ingress protection: IP50 dust protection
• Mounting configuration: Free hanging in-line
• Cable opening range: 0.157" ~ 0.205" (4.00mm ~ 5.20mm)
• Orientation: A
• Insert material: Polyetheretherketone (PEEK)
• Backshell feature: Present

The substitute part K11MA7-P04LJG0-5240 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 parameter differences that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the PRA.M0.4GL.LC52J and K11MA7-P04LJG0-5240 maintain active product status and full compliance with ROHS3 and REACH regulations. Selection between these parts should be based on application-specific thermal and current requirements.

The PRA.M0.4GL.LC52J supports operation to 150°C maximum and carries an 8A current rating. The K11MA7-P04LJG0-5240 supports operation to 120°C maximum with a 10A current rating. Applications requiring sustained operation above 120°C require the LEMO part. Applications with current demands exceeding 8A require the ODU part. Both connectors are suitable for automotive, industrial, medical, and testing equipment applications where ROHS3 compliance and REACH unaffected status are mandatory.

Frequently Asked Questions (FAQ)

Q: Can K11MA7-P04LJG0-5240 be used as a direct replacement for PRA.M0.4GL.LC52J?

A: The K11MA7-P04LJG0-5240 is functionally equivalent for applications operating within -50°C to 120°C and drawing up to 10A. Applications requiring operation above 120°C or with current demands below 8A must use the PRA.M0.4GL.LC52J.

Q: What are the key compatibility factors for these connectors?

A: Both connectors share identical connector type (receptacle, female sockets), position count (4), termination method (solder cup), fastening mechanism (push-pull detent lock), shell material (polysulfone), contact finish (gold), ingress protection (IP50), cable opening range (4.00mm ~ 5.20mm), and insert material (PEEK). These parameters ensure mechanical and electrical compatibility.

Q: Are there differences in packaging or availability?

A: The PRA.M0.4GL.LC52J is available in 1112 units in stock. The K11MA7-P04LJG0-5240 is available in 788 units in bulk packaging. Packaging format differences do not affect connector functionality.

Q: Do both parts meet regulatory requirements for medical applications?

A: Both connectors are listed for medical applications and maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for medical device integration.

Q: What is the significance of shell size designation differences (M04 vs. 1)?

A: Shell size designations reflect manufacturer-specific nomenclature. Both designations correspond to equivalent physical dimensions and mechanical interfaces for 4-position circular connectors in this product category.
