PRA.M0.4GL.LC52N Equivalent & Substitute Parts

Part Overview

The PRA.M0.4GL.LC52N is a 4-position circular connector receptacle manufactured by LEMO, featuring female sockets with solder cup termination and gold-plated mating contacts. This connector is designed for free-hanging inline applications requiring push-pull detent lock fastening. The part is currently active in production with 1048 units in stock. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, application-specific requirements, or design standardization across product lines.

Key Parameters

Substitute Part Grouping Explanation

The K11MA7-P04LJG0-5280 (ODU MEDI-SNAP®) qualifies as a substitute based on the following alignment of critical parameters:

Matching Electrical & Mechanical Specifications:

• Connector type: Receptacle, Female Sockets (4-position)
• Termination method: Solder Cup
• Fastening mechanism: Push-Pull, Detent Lock
• Shell material: Polysulfone (PSU)
• Contact finish: Gold-plated mating surfaces
• Mounting configuration: Free Hanging (In-Line)
• Ingress protection: IP50 - Dust Protected
• Cable opening range: 0.157" ~ 0.205" (4.00mm ~ 5.20mm)
• Insert material: Polyetheretherketone (PEEK)
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

Allowable Parameter Variations:

• Current rating: 10A (substitute) vs. 8A (main part) — higher rating is acceptable
• Operating temperature: -50°C ~ 120°C (substitute) vs. -50°C ~ 150°C (main part) — subset of main part range
• Shell size designation: 1 (substitute) vs. M04 (main part) — equivalent mechanical interface
• Series designation: ODU MEDI-SNAP® (substitute) vs. 1P (main part) — different manufacturer series, same form factor

Parameter Comparison

Engineering Selection Recommendations

Both the PRA.M0.4GL.LC52N and K11MA7-P04LJG0-5280 are active production parts with ROHS3 compliance and REACH unaffected status, making either suitable for new designs and existing applications. The substitute part offers a higher current rating (10A vs. 8A), which provides additional margin for applications operating at or near the 8A specification of the main part. The operating temperature range of the substitute (-50°C ~ 120°C) is a subset of the main part (-50°C ~ 150°C); applications requiring operation above 120°C must use the main part. Both connectors maintain identical mechanical interfaces, fastening mechanisms, and ingress protection ratings, ensuring form-factor compatibility in free-hanging inline mounting configurations.

Frequently Asked Questions (FAQ)

Q: Can the K11MA7-P04LJG0-5280 be used as a direct replacement for the PRA.M0.4GL.LC52N?

A: Yes, for applications operating within -50°C to 120°C and drawing up to 8A. The substitute part maintains identical connector type, position count, termination method, fastening mechanism, shell material, contact finish, and ingress protection. The higher current rating of the substitute (10A) does not affect compatibility.

Q: What is the primary difference between these two parts?

A: The main operational difference is the maximum operating temperature. The PRA.M0.4GL.LC52N operates to 150°C, while the K11MA7-P04LJG0-5280 operates to 120°C. The substitute also specifies brass contact material, whereas the main part does not provide this specification. Both parts are manufactured to the same shell size, position count, and termination standard.

Q: Are the solder cup terminations compatible between these connectors?

A: Yes. Both parts use solder cup termination with identical cable opening specifications (0.157" ~ 0.205" or 4.00mm ~ 5.20mm), ensuring compatible PCB footprints and assembly processes.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the PRA.M0.4GL.LC52N and K11MA7-P04LJG0-5280 are ROHS3 compliant and REACH unaffected, with identical ECCN (EAR99) and HTSUS classifications.

Q: Which part should be selected for high-temperature applications?

A: The PRA.M0.4GL.LC52N must be used for applications requiring operation above 120°C, as it is rated to 150°C. The K11MA7-P04LJG0-5280 is limited to 120°C maximum.

Q: Are the packaging formats different between these parts?

A: The main part (PRA.M0.4GL.LC52N) is listed with packaging designation "-", while the substitute (K11MA7-P04LJG0-5280) is supplied in Bulk packaging. Confirm packaging requirements with your procurement specification.
