AXN440430S Equivalent & Substitute Parts

Part Overview

The AXN440430S is a 40-position rectangular connector header manufactured by Panasonic Electric Works, designed for surface mount applications with outer shroud contacts and gold plating. This component belongs to the P8 series and features a 0.031" (0.80mm) pitch configuration across 2 rows.

The AXN440430S is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this connector.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AXN440430S is determined by the following critical parameters:

• Connector Type: Header with outer shroud contacts (maintains mechanical and electrical interface compatibility)
• Number of Positions: 40 positions (preserves pin count and signal routing)
• Number of Rows: 2 rows (maintains physical layout and contact arrangement)
• Mounting Type: Surface mount (ensures PCB assembly compatibility)
• Contact Finish: Gold (provides equivalent electrical performance and corrosion resistance)
• Mated Stacking Heights: 4mm, 4.5mm, 7mm (ensures mating compatibility with corresponding receptacles)

The substitute part AXK6S40447YG shares these core functional parameters. However, the pitch specification differs: the AXN440430S operates at 0.031" (0.80mm) pitch, while the AXK6S40447YG operates at 0.020" (0.50mm) pitch. This pitch difference represents a fundamental change in connector geometry and contact spacing, requiring careful evaluation of PCB layout and mating connector availability before substitution.

Parameter Comparison

Engineering Selection Recommendations

The AXK6S40447YG is an active product from Panasonic Electric Works and represents the primary substitute option for the obsolete AXN440430S. Both components share identical connector type, position count, row configuration, mounting method, contact finish, and moisture sensitivity classification.

The AXK6S40447YG is RoHS3 compliant and REACH unaffected, providing regulatory alignment for new designs and production environments with stricter environmental standards.

The primary technical distinction is pitch specification: 0.031" (0.80mm) for the AXN440430S versus 0.020" (0.50mm) for the AXK6S40447YG. This difference directly impacts PCB layout, trace routing, and mating connector selection. Substitution is viable only when the receiving system design accommodates the finer pitch geometry and corresponding mating receptacle is available in the 0.020" (0.50mm) pitch configuration.

Frequently Asked Questions (FAQ)

Q: Can the AXK6S40447YG directly replace the AXN440430S without PCB redesign?

A: Direct replacement without PCB modification is not possible due to the pitch difference (0.031" versus 0.020"). The contact spacing on the PCB must match the connector pitch specification. PCB layout redesign is required.

Q: Are the mated stacking heights compatible between these two connectors?

A: Both connectors support identical mated stacking heights of 4mm, 4.5mm, and 7mm. Mating receptacles designed for these stacking heights are compatible with both header types.

Q: What is the significance of the height above board difference?

A: The AXN440430S has a height above board of 0.146" (3.70mm), while the AXK6S40447YG measures 0.130" (3.30mm). This 0.016" (0.40mm) difference may affect clearance calculations in confined assembly spaces but does not impact electrical performance.

Q: Does the AXK6S40447YG meet current environmental compliance requirements?

A: Yes. The AXK6S40447YG is RoHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing and use.

Q: What packaging format is available for the AXK6S40447YG?

A: The AXK6S40447YG is supplied in Tape & Reel (TR) packaging format, suitable for automated assembly processes.

Q: Are both connectors from the same manufacturer?

A: Yes. Both the AXN440430S and AXK6S40447YG are manufactured by Panasonic Electric Works, ensuring consistent quality standards and design philosophy across the product family.
