Key Parameters

Substitute Part Grouping Explanation

Substitution of the AXK5L40337G is determined by strict equivalence across the following critical parameters:

• Connector Configuration: 40 positions, 2 rows, 0.50mm pitch
• Connector Type: Socket with outer shroud contacts
• Mounting Technology: Surface mount
• Contact Material: Gold plating
• Mechanical Features: Board guide integration
• Environmental Classification: MSL 1 (Unlimited)

The substitute part AXK5F40337YG maintains identical electrical and mechanical specifications across all these parameters, enabling direct functional replacement in applications originally designed for the AXK5L40337G.

Parameter Comparison

Engineering Selection Recommendations

The AXK5F40337YG serves as the direct functional equivalent for the obsolete AXK5L40337G. Selection of this substitute is supported by:

Product Status: The substitute part maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Compliance: The AXK5F40337YG is RoHS Compliant, meeting current regulatory requirements for electronic component manufacturing and assembly.

Mechanical Compatibility: Both parts share identical pitch, position count, row configuration, and connector type. The substitute exhibits slightly increased mated stacking height (1.5mm versus 1.2mm) and height above board (0.053" versus 0.045"), which must be verified against PCB layout constraints and mating component specifications in the target application.

Environmental Rating: Both parts carry MSL 1 classification, indicating equivalent moisture sensitivity performance.

Frequently Asked Questions (FAQ)

Q: Can AXK5F40337YG be used as a direct replacement for AXK5L40337G in existing designs?

A: Yes, the AXK5F40337YG maintains electrical and mechanical equivalence across all critical parameters: 40 positions, 0.50mm pitch, 2-row configuration, socket type with outer shroud contacts, surface mount technology, and gold contact finish. Physical height differences must be evaluated against specific PCB and assembly constraints.

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete versus active), series designation (P5KL versus P5KF), mated stacking height (1.2mm versus 1.5mm), height above board (0.045" versus 0.053"), RoHS compliance status (not specified versus compliant), and packaging format (not specified versus Tape & Reel).

Q: Are there any compatibility concerns with the increased height dimensions of the substitute?

A: The substitute part exhibits 0.3mm greater mated stacking height and 0.21mm greater height above board. These dimensional increases must be verified against mating connector specifications, PCB clearance requirements, and enclosure constraints in the target application.

Q: What is the significance of the RoHS Compliant status of the substitute?

A: RoHS Compliance indicates the substitute part meets Restriction of Hazardous Substances regulations, ensuring compatibility with current manufacturing standards and regulatory requirements in most markets.

Q: Does packaging format affect the substitution decision?

A: The substitute is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly. Packaging format does not affect electrical or mechanical compatibility but may influence procurement and handling procedures.
