PRA.M0.9GL.LC39G Equivalent & Substitute Parts

Part Overview

The PRA.M0.9GL.LC39G is a 9-position circular connector receptacle manufactured by LEMO, featuring female sockets with solder cup termination. 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 750 units in stock. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component interchange based on electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PRA.M0.9GL.LC39G is determined by strict alignment of the following critical parameters:

• Connector Type & Position Count: Both main and substitute parts must be receptacles with female sockets in 9-position configuration
• Termination Method: Solder cup termination is required for PCB assembly compatibility
• Fastening Mechanism: Push-pull detent lock fastening ensures mechanical compatibility with mating plugs
• Shell Material & Contact Finish: Polysulfone shell with gold-plated mating contacts maintain electrical and environmental performance
• Ingress Protection: IP50 rating ensures equivalent dust protection
• Cable Opening Dimensions: 0.106" ~ 0.154" (2.70mm ~ 3.90mm) range permits backshell compatibility
• Compliance Standards: ROHS3 compliance and EAR99 classification must be maintained

The ODU K11MA7-P09LCC0-3970 meets these substitution criteria as a functionally equivalent 9-position circular connector receptacle with identical mechanical interfaces and environmental ratings.

Parameter Comparison

Engineering Selection Recommendations

Both the LEMO PRA.M0.9GL.LC39G and ODU K11MA7-P09LCC0-3970 are active production parts with ROHS3 compliance and EAR99 classification. Selection between these parts depends on application-specific electrical and thermal requirements:

• For applications requiring 3A current capacity and operating temperatures up to 150°C: The LEMO PRA.M0.9GL.LC39G is the appropriate selection, as it provides the full specified current rating and extended temperature range.

• For applications with current requirements up to 2.75A and operating temperatures up to 120°C: The ODU K11MA7-P09LCC0-3970 is functionally equivalent and provides an alternative sourcing option. This part is available in bulk packaging with 821 units in stock.

Both parts maintain identical mechanical interfaces, shell materials, contact finishes, and ingress protection ratings, ensuring interchangeability within the specified electrical and thermal operating windows.

Frequently Asked Questions (FAQ)

Q: Can the ODU K11MA7-P09LCC0-3970 be used as a direct replacement for the LEMO PRA.M0.9GL.LC39G?

A: The ODU part is mechanically and electrically compatible within defined limits. The ODU connector is rated for 2.75A maximum current and -50°C to 120°C operating temperature, compared to the LEMO part's 3A rating and -50°C to 150°C range. Direct substitution is valid only when application requirements do not exceed the ODU part's electrical and thermal specifications.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution is based on: 9-position configuration, receptacle with female sockets, solder cup termination, push-pull detent lock fastening, polysulfone shell material, gold-plated mating contacts, IP50 ingress protection, identical cable opening dimensions, PEEK insert material, and compliance certifications (ROHS3, EAR99, REACH Unaffected).

Q: Are there packaging differences between these parts?

A: The LEMO PRA.M0.9GL.LC39G is supplied in standard packaging with 750 units in stock. The ODU K11MA7-P09LCC0-3970 is supplied in bulk packaging with 821 units in stock. Both are new original parts in active production.

Q: What applications are supported by these connectors?

A: Both parts support automotive, industrial, medical, and testing equipment applications. The LEMO part additionally lists these applications explicitly. Application suitability depends on meeting the specific current and temperature requirements of each part.

Q: How do the contact materials differ?

A: The LEMO part does not specify contact material in the provided data. The ODU part specifies brass contacts with gold plating. Both maintain gold-plated mating contact finishes for equivalent electrical performance.
