AXN440330P Equivalent & Substitute Parts

Part Overview

The AXN440330P 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 is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing production support and design continuity. The part operates within MSL 1 (unlimited moisture sensitivity), indicating suitability for standard storage and handling conditions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AXN440330P is determined by the following critical parameters:

• Connector Type: Header with outer shroud contacts (mechanical and electrical interface requirement)
• Number of Positions: 40 positions (pin count and contact arrangement)
• Number of Rows: 2 rows (physical layout constraint)
• Mounting Type: Surface mount (assembly process compatibility)
• Contact Finish: Gold (electrical performance and corrosion resistance)
• Manufacturer: Panasonic Electric Works (design lineage and quality assurance)

The substitute part AXK6S40437YG shares the same connector type, position count, row configuration, mounting method, and contact finish. However, it operates at a different pitch specification (0.020" vs. 0.031"), which represents a fundamental geometric difference. This pitch variation affects PCB layout, mating interface dimensions, and mechanical clearances. The substitute also exhibits different mated stacking heights and height above board measurements, reflecting its distinct mechanical envelope within the P5KS series.

Parameter Comparison

Engineering Selection Recommendations

The AXK6S40437YG serves as an active-status alternative to the obsolete AXN440330P within the Panasonic Electric Works connector portfolio. Both components maintain identical moisture sensitivity classification and share core functional attributes: 40-position configuration, dual-row layout, surface mount assembly, and gold contact finish.

The primary distinction lies in pitch specification. The AXK6S40437YG operates at 0.020" (0.50mm) pitch compared to the AXN440330P's 0.031" (0.80mm) pitch. This geometric difference necessitates PCB redesign, including modified trace routing, pad spacing, and component placement. The substitute's increased height above board (0.130" vs. 0.107") and altered mated stacking heights (4mm, 4.5mm, 7mm vs. 3mm, 4.6mm, 6mm) further require mechanical clearance verification within the assembly.

The AXK6S40437YG's active product status and RoHS compliance provide advantages for new designs and regulatory alignment. Selection of this substitute requires confirmation that the pitch modification and dimensional changes are compatible with the target application's PCB layout and mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Can AXK6S40437YG directly replace AXN440330P without PCB modification?

A: No. The pitch difference (0.031" vs. 0.020") requires PCB redesign. Pad spacing, trace routing, and component placement must be recalculated for the substitute part's geometry.

Q: What is the significance of the pitch specification in connector selection?

A: Pitch defines the center-to-center distance between adjacent contacts. It determines PCB pad layout, mating interface compatibility, and mechanical clearances. Pitch changes are not interchangeable without design revision.

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

A: No. The different pitch specifications require different mating connectors. AXN440330P mates with 0.031" pitch receptacles, while AXK6S40437YG requires 0.020" pitch receptacles.

Q: What does the height above board specification indicate?

A: Height above board measures the vertical distance from the PCB surface to the highest point of the connector header. This affects available clearance for adjacent components and enclosure design.

Q: Why is the AXN440330P listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The AXK6S40437YG represents Panasonic's current-generation equivalent within the P5KS series.

Q: Does RoHS compliance affect substitution decisions?

A: RoHS compliance is relevant for applications subject to regulatory requirements. The AXK6S40437YG's RoHS compliance provides advantage for regulated markets, though the AXN440330P's RoHS status is not specified in available documentation.

Q: What are mated stacking heights?

A: Mated stacking heights specify the vertical distance between the header and mating receptacle at different engagement depths. These values are critical for mechanical design and clearance planning in stacked connector applications.
