AXN350038S Equivalent & Substitute Parts

Part Overview

The AXN350038S is a 50-position rectangular connector socket manufactured by Panasonic Electric Works, designed for surface mount applications with center strip 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 0.031" (0.80mm) pitch configuration with dual-row arrangement and board guide features, operating at mated stacking heights of 3mm, 4mm, and 5mm.

Key Parameters

Substitute Part Grouping Explanation

Substitute identification for the AXN350038S is based on the following critical parameters that define functional compatibility:

Primary Compatibility Criteria:

• Connector type: Socket with center strip contacts
• Number of positions: 50
• Mounting technology: Surface mount
• Contact material and finish: Gold plating
• Moisture sensitivity classification: MSL 1 (Unlimited)

The identified substitute part AXK5S50047YG shares the core functional characteristics of the main part across connector type, position count, mounting method, and contact finish. However, this substitute introduces a significant pitch modification from 0.031" (0.80mm) to 0.020" (0.50mm), which represents a fundamental change in the connector's physical footprint and mating interface. This pitch difference necessitates careful evaluation during component selection, as it affects PCB layout, mating connector compatibility, and overall assembly requirements.

Parameter Comparison

Engineering Selection Recommendations

The AXK5S50047YG substitute part is classified as active product status, ensuring ongoing availability and manufacturing support compared to the obsolete AXN350038S. The substitute demonstrates ROHS3 compliance, providing regulatory advantage for applications subject to hazardous substance restrictions.

The primary consideration for component selection is the pitch modification from 0.031" (0.80mm) to 0.020" (0.50mm). This change directly impacts PCB layout density, trace routing, and mating connector specifications. The substitute's increased height above board (0.120" versus 0.087") and modified stacking height range (4mm, 5mm, 6mm versus 3mm, 4mm, 5mm) must be evaluated against available board space and assembly clearance requirements.

Both parts maintain identical moisture sensitivity classification and gold contact finish specifications, supporting equivalent performance in environmental exposure conditions. Selection between these parts depends on whether the application can accommodate the pitch and dimensional modifications introduced by the substitute.

Frequently Asked Questions (FAQ)

Q: Can AXK5S50047YG directly replace AXN350038S without PCB redesign?

A: Direct replacement without PCB modification is not possible due to the pitch change from 0.031" (0.80mm) to 0.020" (0.50mm). This difference affects pad spacing, trace routing, and mating connector compatibility. PCB layout revision is required.

Q: Are the contact finish specifications equivalent between these parts?

A: Both parts feature gold contact finish, providing equivalent electrical and corrosion resistance characteristics for mating interface performance.

Q: What is the significance of the product status difference?

A: The AXN350038S is classified as obsolete, indicating discontinued manufacturing and limited availability. The AXK5S50047YG is active product, ensuring continued supply and manufacturing support.

Q: How do the moisture sensitivity levels compare?

A: Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions and no special storage or handling requirements during assembly.

Q: What packaging format is available for the substitute part?

A: The AXK5S50047YG is supplied in Tape & Reel (TR) packaging format, suitable for automated assembly processes.

Q: Are there compliance differences between these parts?

A: The substitute part (AXK5S50047YG) is ROHS3 compliant and REACH unaffected, providing regulatory compliance advantages. The main part specifications do not include these compliance certifications.
