Key Parameters

Substitute Part Grouping Explanation

Substitution of the AXN440530P is determined by the following critical parameters:

• Connector Type: Header with outer shroud contacts (functional requirement)
• Number of Positions: 40 positions (electrical requirement)
• Number of Rows: 2 rows (physical layout requirement)
• Mounting Type: Surface mount (assembly requirement)
• Contact Finish: Gold plating (electrical performance requirement)
• Moisture Sensitivity Level: MSL 1 or better (environmental requirement)

The substitute part AXK6S40537YG maintains compatibility across these core parameters. However, the pitch specification differs between the main part (0.031"/0.80mm) and the substitute (0.020"/0.50mm), representing a dimensional change that affects PCB layout and mating interface design. The substitute operates with active product status and includes RoHS compliance certification, providing improved supply chain availability and regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

The AXK6S40537YG serves as the active substitute for the obsolete AXN440530P. Selection of this substitute is supported by:

• Product Status Alignment: The substitute maintains active manufacturing status, ensuring long-term supply chain availability and production support.
• Regulatory Compliance: RoHS compliance and REACH unaffected status provide regulatory alignment for applications subject to environmental directives.
• Functional Equivalence: Both parts maintain identical connector type, position count, row configuration, mounting method, contact finish, and moisture sensitivity classification.
• Physical Compatibility: Mated stacking heights remain consistent across both parts, supporting existing mating interface designs.

The primary design consideration is the pitch change from 0.031" (0.80mm) to 0.020" (0.50mm), which requires PCB layout modification and updated mating connector specifications. This dimensional change does not affect electrical performance but necessitates mechanical redesign of the interconnection interface.

Frequently Asked Questions (FAQ)

Q: Can the AXK6S40537YG be used as a direct drop-in replacement for the AXN440530P?

A: The AXK6S40537YG is functionally equivalent but not a direct drop-in replacement. The pitch specification differs (0.031" versus 0.020"), requiring PCB layout modification and updated mating connector selection. Mated stacking heights and contact finish remain compatible.

Q: What is the significance of the pitch change between these parts?

A: Pitch defines the center-to-center spacing between connector positions. The reduction from 0.031" to 0.020" requires redesign of the PCB footprint and selection of a mating connector with matching 0.020" pitch specifications. This change affects board layout density and interconnection design.

Q: Are both parts suitable for the same environmental conditions?

A: Both parts maintain MSL 1 (Unlimited) moisture sensitivity classification, indicating equivalent environmental performance. The substitute includes RoHS compliance and REACH unaffected status, providing additional regulatory assurance for applications subject to environmental directives.

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

A: The AXK6S40537YG is supplied in Tape & Reel (TR) packaging format, suitable for automated assembly processes. The main part packaging format is not specified in available documentation.

Q: Why is the AXN440530P classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The AXK6S40537YG, classified as active, represents the current manufacturing equivalent and is recommended for new designs and ongoing production requirements.
