AXN440330S Equivalent & Substitute Parts

Part Overview

The AXN440330S 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 AXN440330S is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AXN440330S are identified based on the following critical parameters that determine functional and mechanical compatibility:

• Connector Type: Header with outer shroud contacts (maintained across substitutes)
• Number of Positions: 40-position configuration (maintained)
• Number of Rows: 2-row layout (maintained)
• Mounting Type: Surface mount technology (maintained)
• Contact Finish: Gold plating (maintained)
• Manufacturer: Panasonic Electric Works (maintained)

The AXK6S40447YG qualifies as a substitute part. While it operates at a different pitch specification (0.020" versus 0.031"), it maintains the core functional parameters of a 40-position, 2-row, surface-mount header with gold contacts and outer shroud design. The pitch difference results in different board-level spacing requirements and mated stacking heights, which must be evaluated against specific application constraints.

Parameter Comparison

Engineering Selection Recommendations

The AXK6S40447YG is an active product from Panasonic Electric Works and represents the primary substitute option for the obsolete AXN440330S. Both components share identical core specifications: 40-position, 2-row, surface-mount header configuration with gold-plated outer shroud contacts and unlimited moisture sensitivity rating.

The AXK6S40447YG operates at a finer pitch (0.020" versus 0.031"), resulting in a more compact footprint and increased board-level density. This pitch difference necessitates PCB layout modifications, including adjusted trace spacing and connector pad positioning. The substitute part exhibits a slightly increased height above board (0.130" versus 0.107") and correspondingly higher mated stacking heights (4mm, 4.5mm, 7mm versus 3mm, 4.6mm, 6mm).

Selection of the AXK6S40447YG requires confirmation that the application design accommodates the pitch transition and revised mechanical envelope. The active product status of the AXK6S40447YG ensures ongoing availability and supply chain continuity compared to the obsolete AXN440330S.

Frequently Asked Questions (FAQ)

Q: Can the AXK6S40447YG directly replace the AXN440330S without PCB modifications?

A: No. The pitch difference (0.020" versus 0.031") requires PCB layout redesign. Connector pad spacing, trace routing, and mounting hole positions must be recalculated for the substitute part.

Q: What is the primary difference between these two parts?

A: The main difference is pitch specification. The AXN440330S uses 0.031" (0.80mm) pitch, while the AXK6S40447YG uses 0.020" (0.50mm) pitch. Both maintain 40 positions across 2 rows with identical connector type and contact finish.

Q: Are both parts compatible with the same mating connectors?

A: No. The different pitch specifications require different mating connectors. Mating components must be selected based on the specific pitch of the header being used.

Q: What is the packaging difference?

A: The AXN440330S packaging is not specified in available data. The AXK6S40447YG is supplied in Tape & Reel (TR) format, standard for surface-mount production environments.

Q: Does the height difference affect component placement?

A: Yes. The AXK6S40447YG has a height above board of 0.130" compared to 0.107" for the AXN440330S. This 0.023" difference must be considered in enclosure design, clearance planning, and assembly stacking constraints.

Q: Are both parts RoHS compliant?

A: The AXK6S40447YG is ROHS3 compliant. RoHS compliance status for the AXN440330S is not specified in available data.
