PKA.M0.5GL.LG Equivalent & Substitute Parts

Part Overview

The PKA.M0.5GL.LG is a 5-position circular connector receptacle manufactured by LEMO, featuring female sockets with solder cup termination. This connector is designed for panel mount applications requiring push-pull detent lock fastening and operates across a temperature range of -50°C to 150°C. The part is actively produced and maintains 801 units in current inventory stock.

Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable, to support supply chain flexibility, or to accommodate specific application requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PKA.M0.5GL.LG are identified based on strict equivalence across the following critical parameters:

• Connector Configuration: Receptacle with female sockets, 5-position arrangement
• Termination Method: Solder cup for direct PCB or wire attachment
• Fastening Mechanism: Push-pull detent lock for secure mating
• Mounting Configuration: Panel mount with front and rear side nut capability
• Contact Interface: Gold-plated mating surface for reliable electrical connection
• Shell Composition: Polysulfone (PSU) plastic construction
• Environmental Protection: IP50 dust protection rating
• Insert Material: Polyetheretherketone (PEEK) for mechanical stability
• Regulatory Compliance: ROHS3 and REACH compliance status

The substitute part G51MA7-P05LJG0-0070 (ODU MEDI-SNAP®) meets these core substitution criteria while maintaining functional and mechanical compatibility within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

Both the PKA.M0.5GL.LG and G51MA7-P05LJG0-0070 are actively produced components with ROHS3 compliance and unlimited moisture sensitivity ratings. Selection between these parts is based on application-specific requirements:

The PKA.M0.5GL.LG supports an extended operating temperature range of -50°C to 150°C, making it suitable for applications requiring higher temperature performance. The G51MA7-P05LJG0-0070 operates within -50°C to 120°C and provides a marginally higher current rating of 7.5A compared to the 7A rating of the LEMO part.

Both connectors maintain identical mechanical interfaces, fastening mechanisms, and electrical contact specifications. Component selection should be driven by specific thermal and current requirements of the target application, with consideration for supply chain availability and inventory status.

Frequently Asked Questions (FAQ)

Q: Can G51MA7-P05LJG0-0070 be used as a direct replacement for PKA.M0.5GL.LG?

A: Yes, within applications operating at or below 120°C. The substitute part maintains identical connector configuration, termination method, fastening mechanism, and contact specifications. Applications requiring operation above 120°C must use the PKA.M0.5GL.LG due to its extended temperature rating to 150°C.

Q: What are the key compatibility factors between these two connectors?

A: Compatibility is ensured through matching 5-position female socket configuration, solder cup termination, push-pull detent lock fastening, panel mount design, gold-plated contacts, PSU shell material, IP50 protection, and PEEK insert material. Both parts are ROHS3 compliant with unlimited MSL ratings.

Q: Are there differences in current handling capacity?

A: The ODU part (G51MA7-P05LJG0-0070) is rated for 7.5A, while the LEMO part (PKA.M0.5GL.LG) is rated for 7A. For applications requiring current levels between 7A and 7.5A, the ODU substitute provides additional margin.

Q: What packaging considerations apply to these parts?

A: The PKA.M0.5GL.LG is supplied in standard packaging with 801 units currently in stock. The G51MA7-P05LJG0-0070 is supplied in bulk packaging with 842 units in current inventory. Packaging format does not affect electrical or mechanical compatibility.

Q: Are both parts suitable for automotive, industrial, and medical applications?

A: Both connectors support automotive, industrial, medical, and testing equipment applications. The LEMO part explicitly lists these application categories, while the ODU substitute supports industrial, medical, military, and testing equipment applications. Overlap in medical and industrial applications confirms compatibility for these use cases.
