PRA.M0.5GL.LC65R Equivalent & Substitute Parts

Part Overview

The PRA.M0.5GL.LC65R is a 5-position circular plastic push-pull connector receptacle manufactured by LEMO. This connector features female sockets with solder cup termination and is designed for free-hanging in-line mounting applications. The component is constructed with a polysulfone shell and polyetheretherketone insert, providing durability across automotive, industrial, medical, and testing equipment applications. With an active product status and 995 units in stock, this connector remains a current production component. Identifying equivalent substitute parts is necessary to ensure supply chain continuity, evaluate alternative sourcing options, and maintain design flexibility across production cycles.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PRA.M0.5GL.LC65R is determined by strict alignment of the following critical parameters:

Primary Matching Criteria:

• Connector type must be receptacle with female sockets
• Position count must equal 5
• Termination method must be solder cup
• Fastening mechanism must be push-pull compatible
• Mounting configuration must support free-hanging in-line installation
• Shell material must be polysulfone (PSU)
• Contact finish must be gold-plated for mating surfaces
• Insert material must be polyetheretherketone (PEEK)
• Ingress protection rating must meet or exceed IP50

Secondary Compatibility Parameters:

• Operating temperature range must encompass the application requirements
• Shielding configuration must match unshielded specification
• Backshell presence must be consistent

The substitute part K11MA7-P05LJG0-6520 from ODU meets these criteria as a functionally equivalent 5-position circular connector receptacle with female sockets, solder cup termination, push-pull fastening, polysulfone shell, gold contact finish, PEEK insert, and IP50 ingress protection rating.

Parameter Comparison

Engineering Selection Recommendations

Both the PRA.M0.5GL.LC65R and K11MA7-P05LJG0-6520 maintain active product status with current manufacturing support. The LEMO connector operates across a temperature range of -50°C to 150°C, while the ODU substitute operates from -50°C to 120°C. Applications requiring sustained operation above 120°C must utilize the LEMO part exclusively.

The ODU K11MA7-P05LJG0-6520 includes detent lock functionality in addition to push-pull fastening, providing enhanced mechanical retention. Both connectors share identical ECCN (EAR99) and HTSUS (8536.69.4020) classifications, ensuring equivalent regulatory treatment for export and tariff purposes.

The ODU part carries ROHS3 compliance and MSL Level 1 moisture sensitivity rating, supporting modern manufacturing and storage requirements. Both connectors feature identical shell material (polysulfone), contact finish (gold), insert material (PEEK), and ingress protection (IP50), ensuring mechanical and electrical compatibility in equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can the K11MA7-P05LJG0-6520 directly replace the PRA.M0.5GL.LC65R in all applications?

A: Direct substitution is valid for applications operating within the -50°C to 120°C temperature range. Applications requiring operation above 120°C must continue using the PRA.M0.5GL.LC65R, as the ODU substitute is rated only to 120°C maximum.

Q: What is the significance of the detent lock feature on the ODU connector?

A: The K11MA7-P05LJG0-6520 incorporates detent lock functionality alongside push-pull fastening. This provides additional mechanical retention during mating and unmating cycles. The PRA.M0.5GL.LC65R uses push-pull fastening without detent lock specification.

Q: Are the shell sizes equivalent between these two connectors?

A: The PRA.M0.5GL.LC65R specifies shell size M05, while the K11MA7-P05LJG0-6520 specifies shell size 1. Both are 5-position connectors with identical functional geometry for solder cup termination and free-hanging mounting.

Q: Do both connectors meet the same regulatory classifications?

A: Yes. Both connectors share identical ECCN classification (EAR99) and HTSUS code (8536.69.4020), ensuring equivalent treatment for export control and tariff purposes.

Q: What are the material specifications for both connectors?

A: Both connectors feature polysulfone (PSU) shell material, polyetheretherketone (PEEK) insert material, and gold-plated mating contacts. The PRA.M0.5GL.LC65R specifies UL94 V-0 flammability rating; the ODU part does not specify this parameter in the provided data.

Q: Are there inventory considerations for selecting between these parts?

A: The PRA.M0.5GL.LC65R has 995 units in stock, while the K11MA7-P05LJG0-6520 has 799 units available. Both maintain active production status with current availability.

Q: What is the cable opening specification for the ODU connector?

A: The K11MA7-P05LJG0-6520 accommodates cable diameters from 0.209" to 0.256" (5.30mm to 6.50mm). The PRA.M0.5GL.LC65R does not specify cable opening parameters in the provided data.
