Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AXN440C330J is determined by the following critical parameters:

• Connector Type: Header with outer shroud contacts
• Number of Positions: 40 positions
• Number of Rows: 2 rows
• Mounting Type: Surface mount
• Contact Finish: Gold plating
• Moisture Sensitivity Level: MSL 1 or equivalent

The substitute part AXK6S40447YG shares the same connector type, position count, row configuration, mounting method, and contact finish. However, this substitute operates at a different pitch specification (0.020" versus 0.031"), which represents a fundamental geometric difference in contact spacing. This pitch variance affects mechanical compatibility with mating connectors and printed circuit board layouts.

Parameter Comparison

Engineering Selection Recommendations

The AXK6S40447YG is listed as an active substitute for the obsolete AXN440C330J. Both components maintain identical position counts, row configurations, and contact finish specifications. The substitute part carries ROHS3 compliance certification, whereas the original part does not specify compliance status.

The primary distinction between these parts is the pitch specification: the original operates at 0.031" (0.80mm) while the substitute operates at 0.020" (0.50mm). This geometric difference directly impacts board layout compatibility and mating connector selection. The substitute also exhibits increased height above board (0.130" versus 0.107") and different mated stacking height options.

Selection of the AXK6S40447YG requires confirmation that the receiving application can accommodate the modified pitch spacing and increased height profile. The active product status of the substitute ensures ongoing availability and supply chain continuity compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can AXK6S40447YG directly replace AXN440C330J in existing designs?

A: Direct replacement requires design verification. While both parts share 40 positions, 2 rows, and gold contact finish, the pitch difference (0.031" versus 0.020") necessitates confirmation of mating connector compatibility and printed circuit board layout accommodation.

Q: What is the significance of the pitch difference?

A: Pitch defines the center-to-center spacing between adjacent contacts. The 0.031" pitch of the original part differs from the 0.020" pitch of the substitute, resulting in different overall connector widths and requiring compatible mating connectors and board footprints.

Q: Does the height difference affect compatibility?

A: The substitute part exhibits 0.023" greater height above board (0.130" versus 0.107") and different mated stacking height options (4mm, 4.5mm, 7mm versus 3mm, 4.6mm, 6mm). Applications with height constraints or specific stacking requirements must evaluate this difference.

Q: What packaging format is available for the substitute?

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

Q: Are both parts compliant with environmental standards?

A: Both parts maintain MSL 1 (Unlimited) moisture sensitivity classification. The substitute part carries ROHS3 compliance certification. The original part does not specify RoHS status.
