PKA.M0.2GL.LR Equivalent & Substitute Parts

Part Overview

The PKA.M0.2GL.LR is a 2-position circular plastic push-pull connector receptacle manufactured by LEMO. This connector features female sockets with solder cup termination, panel mount bulkhead installation, and is rated for 10A continuous current. The connector is constructed with a polysulfone (PSU) shell and polyetheretherketone (PEEK) insert, providing durability across automotive, industrial, medical, and testing equipment applications. With 681 units in current stock and active product status, this connector remains available for new designs and replacement applications. Identifying equivalent substitute parts ensures design flexibility, supply chain continuity, and access to alternative sourcing options when the primary part becomes unavailable or when design requirements necessitate alternative specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PKA.M0.2GL.LR is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Receptacle with female sockets
• Number of positions: 2
• Termination method: Solder cup
• Fastening mechanism: Push-pull with detent lock
• Mounting configuration: Panel mount, bulkhead installation
• Shell material: Polysulfone (PSU)
• Insert material: Polyetheretherketone (PEEK)
• Ingress protection rating: IP50 or equivalent
• Shielding configuration: Unshielded
• Orientation: A

Allowable Parameter Variations:

• Current rating: Substitute parts may exceed the 10A specification
• Operating temperature range: Substitute parts may have narrower or equivalent temperature ranges
• Contact finish: Variations in contact plating materials are permissible
• Color options: Gray or alternative colors are acceptable
• Shell size designation: Variations in size nomenclature (M02 versus 1) are acceptable if mechanical compatibility is maintained

The substitute part G51MA7-P02LPH0-0020 from ODU meets all mandatory matching parameters while providing enhanced current rating (14A) and gold-plated contacts.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (PKA.M0.2GL.LR): Select the PKA.M0.2GL.LR when the design operates within the specified 10A current requirement and requires the full -50°C to 150°C operating temperature range. This part maintains active product status with 681 units in stock, ensuring immediate availability for production and field replacement applications.

Substitute Part Selection (G51MA7-P02LPH0-0020): The ODU G51MA7-P02LPH0-0020 serves as a direct functional substitute when supply constraints affect the primary part or when the application benefits from enhanced current capacity (14A). This substitute is ROHS3 compliant and REACH unaffected, meeting modern regulatory requirements. The gold-plated brass contacts provide enhanced corrosion resistance compared to unspecified contact finishes in the primary part.

Temperature Consideration: Applications requiring operation above 120°C must retain the PKA.M0.2GL.LR, as the substitute part's maximum operating temperature is limited to 120°C. For applications operating within -50°C to 120°C, both parts are functionally equivalent.

Compliance and Regulatory Status: Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4020) classifications. The substitute part provides documented RoHS3 compliance and REACH unaffected status, supporting regulatory documentation requirements for medical, industrial, and automotive applications.

Frequently Asked Questions (FAQ)

Q: Can the G51MA7-P02LPH0-0020 directly replace the PKA.M0.2GL.LR in all applications?

A: The G51MA7-P02LPH0-0020 provides direct functional replacement for applications operating within -50°C to 120°C. Applications requiring temperatures above 120°C must use the PKA.M0.2GL.LR. Both connectors share identical mechanical interfaces, fastening mechanisms, and electrical contact configurations for 2-position solder cup termination.

Q: What are the key differences between these two connectors?

A: The primary differences are current rating (10A versus 14A), maximum operating temperature (150°C versus 120°C), and contact finish specification (unspecified versus gold-plated brass). The substitute part provides higher current capacity and documented contact material specifications. Shell and insert materials, connector type, and mounting configurations are identical.

Q: Are there any compatibility issues with existing cable assemblies?

A: No compatibility issues exist. Both connectors use identical push-pull detent lock fastening, 2-position solder cup termination, and A-orientation mating interfaces. Existing cable assemblies designed for the PKA.M0.2GL.LR mate directly with the G51MA7-P02LPH0-0020 without modification.

Q: Which part should be specified for new medical device designs?

A: The G51MA7-P02LPH0-0020 is recommended for new medical device designs due to documented ROHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level 1 (unlimited) rating. Both parts support medical applications, but the substitute provides enhanced regulatory documentation.

Q: What is the significance of the gold-plated contact finish in the substitute part?

A: Gold plating on brass contacts provides enhanced corrosion resistance and improved contact reliability in harsh environments. This specification is particularly beneficial for automotive and industrial applications subject to moisture, temperature cycling, and vibration. The primary part does not specify contact finish, making the substitute's gold plating a documented advantage.

Q: Can the substitute part handle higher current applications?

A: Yes. The G51MA7-P02LPH0-0020 is rated for 14A continuous current, compared to the primary part's 10A rating. Applications requiring current capacity between 10A and 14A benefit from the substitute part's enhanced rating. Both parts maintain identical voltage and power handling characteristics for 2-position configurations.

Q: Are both parts available in the same packaging options?

A: The PKA.M0.2GL.LR is available in standard packaging with 681 units in current stock. The G51MA7-P02LPH0-0020 is supplied in bulk packaging with 1058 units in stock. Both parts maintain active product status and are available for immediate shipment.
