AXK5L50337G Equivalent & Substitute Parts

Part Overview

The AXK5L50337G is a 50-position rectangular connector socket manufactured by Panasonic Electric Works, designed for surface mount applications with outer shroud contacts and gold plating. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing production and maintenance applications. The connector features a 0.020" (0.50mm) pitch configuration across 2 rows, with board guide features and surface mount mounting type. Due to its obsolete status, equivalent parts from the same manufacturer's active product lines are necessary to ensure supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AXK5L50337G is based on strict electrical and mechanical parameter matching within Panasonic Electric Works' rectangular connector portfolio. The critical parameters determining substitutability are:

• Connector Type: Socket, Outer Shroud Contacts (must match exactly)
• Number of Positions: 50 (electrical interface requirement)
• Pitch: 0.020" (0.50mm) (mechanical compatibility with mating connectors)
• Number of Rows: 2 (physical layout requirement)
• Mounting Type: Surface Mount (PCB assembly compatibility)
• Contact Finish: Gold (electrical performance and corrosion resistance)
• Features: Board Guide (mechanical alignment requirement)

The AXK5F50537YG qualifies as a direct substitute because it maintains all critical parameters while transitioning from the obsolete P5KL series to the active P5KF series. Both parts share identical electrical and mechanical specifications for the core connector interface.

Parameter Comparison

Engineering Selection Recommendations

The AXK5F50537YG is the appropriate substitute for the obsolete AXK5L50337G based on the following engineering criteria:

Product Status Alignment: The substitute part is active and currently manufactured, ensuring long-term supply availability compared to the obsolete original part.

Electrical Compatibility: Both parts maintain identical connector specifications (50 positions, 0.020" pitch, 2 rows, gold contact finish), ensuring direct electrical interface compatibility with existing mating connectors and PCB designs.

Mechanical Compatibility: The substitute retains the same connector type, mounting method, and board guide features. The increased height above board (0.073" versus 0.045") and expanded mated stacking height options (2mm, 2.5mm versus 1.2mm) represent design improvements in the active series and do not prevent substitution in standard applications.

Compliance Status: The substitute part is RoHS Compliant, meeting current regulatory requirements for electronic components in most markets.

Moisture Sensitivity: Both parts share MSL 1 (Unlimited) classification, indicating no moisture-related handling restrictions.

Frequently Asked Questions (FAQ)

Q: Can AXK5F50537YG be used as a direct replacement for AXK5L50337G in existing designs?

A: Yes. The substitute maintains all critical electrical and mechanical parameters: 50-position socket configuration, 0.020" pitch, 2-row layout, surface mount type, gold contacts, and board guide features. The connector interface is fully compatible with existing mating components.

Q: What are the differences between these two parts?

A: The primary differences are product status (obsolete versus active), height above board (0.045" versus 0.073"), mated stacking height options (1.2mm versus 2mm/2.5mm), RoHS compliance status, and packaging format. These differences do not affect electrical or core mechanical compatibility.

Q: Does the increased height above board affect PCB assembly?

A: The AXK5F50537YG has a greater height above board (0.073" versus 0.045"). This must be evaluated against specific PCB clearance requirements and component placement constraints in your design. The connector remains mechanically compatible with standard mating connectors.

Q: Is the substitute part available in the same packaging as the original?

A: The substitute is supplied in Tape & Reel (TR) packaging, which is standard for high-volume surface mount applications. The original part's packaging format was not specified in available documentation.

Q: Are there any compliance or certification differences?

A: The substitute part is RoHS Compliant, meeting current environmental regulations. Both parts share MSL 1 classification and EAR99 ECCN status, ensuring equivalent handling and export compliance characteristics.
