PRA.M1.0GL.LC39J Circular Connector Receptacle - Equivalent & Substitute Parts

Part Overview

The PRA.M1.0GL.LC39J is a 10-position circular connector receptacle manufactured by LEMO, designed for applications requiring female socket termination with solder cup connections. This connector is classified as a receptacle with female sockets, featuring a push-pull detent lock fastening mechanism and IP50 dust protection rating. The part is currently in active production status with 946 units in stock inventory.

Equivalent and substitute parts are identified when alternative manufacturers produce connectors that maintain compatibility across the critical electrical and mechanical parameters defined for this product category, including connector type, position count, termination method, fastening mechanism, and environmental operating specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PRA.M1.0GL.LC39J are identified based on strict equivalence across the following critical parameters:

• Connector type classification (Receptacle, Female Sockets)
• Position count (10 positions)
• Termination method (Solder Cup)
• Fastening mechanism (Push-Pull, Detent Lock)
• Shell material composition (Polysulfone PSU)
• Contact finish specification (Gold plating)
• Ingress protection rating (IP50)
• Mounting configuration (Free Hanging In-Line)
• Compliance certifications (ROHS3, REACH Unaffected, EAR99)

The substitute part K11MA7-P10LCC0-3940 from ODU maintains compatibility across these core parameters while operating within the defined electrical and environmental envelope for this connector category.

Parameter Comparison

Engineering Selection Recommendations

Both the PRA.M1.0GL.LC39J and K11MA7-P10LCC0-3940 maintain active production status and full compliance with ROHS3 regulations and REACH directives. Both connectors carry EAR99 export classification and unlimited moisture sensitivity ratings.

The primary electrical difference between these parts is the current rating specification: the LEMO part is rated at 3A while the ODU substitute is rated at 2.75A. The operating temperature range for the LEMO connector extends to 150°C, whereas the ODU part operates to a maximum of 120°C. These differences must be evaluated against the specific application requirements to determine suitability for substitution in any given circuit design or system integration scenario.

Frequently Asked Questions (FAQ)

Q: What determines whether K11MA7-P10LCC0-3940 can substitute for PRA.M1.0GL.LC39J?

A: Substitution is valid when the application requirements do not exceed the ODU part's current rating of 2.75A or operating temperature maximum of 120°C. All other mechanical, electrical, and compliance parameters are equivalent between the two connectors.

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

A: Both connectors feature solder cup termination with identical cable opening specifications (0.106" ~ 0.154" / 2.70mm ~ 3.90mm), ensuring mechanical and electrical compatibility at the termination interface.

Q: Do both connectors meet the same environmental protection standards?

A: Both connectors provide IP50 ingress protection rating and operate across the -50°C to 120°C range (with the LEMO part extending to 150°C). Both are rated MSL 1 (Unlimited moisture sensitivity).

Q: What is the difference in shell size designation between M10 and 1?

A: The LEMO part specifies shell size as M10, while the ODU part specifies shell size as 1. Both connectors maintain mechanical compatibility through identical cable opening dimensions and push-pull detent lock fastening mechanisms.

Q: Are both connectors RoHS and REACH compliant?

A: Both the PRA.M1.0GL.LC39J and K11MA7-P10LCC0-3940 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.
