Key Parameters

Substitute Part Grouping Explanation

Substitution of the AXG7440J7 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Pitch: 0.014" (0.35mm)
• Number of Rows: 2
• Mounting Type: Surface Mount
• Contact Finish: Gold
• Mated Stacking Height: 0.6mm
• Height Above Board: 0.023" (0.59mm)
• RoHS Compliance: Required
• Moisture Sensitivity Level: 1 (Unlimited)

The AXF5D4412 qualifies as a substitute based on matching all critical parameters. The primary functional difference is the position count: the AXG7440J7 provides 46 positions (44 + 2 Power), while the AXF5D4412 provides 44 positions. This difference reflects the connector type distinction—socket versus receptacle—within the same mechanical and electrical framework. Both components maintain identical pitch, row configuration, mounting methodology, contact finish, and compliance certifications.

Engineering Selection Recommendations

The AXF5D4412 is the designated substitute for the obsolete AXG7440J7. Selection of this alternative is supported by the following engineering criteria:

Product Status: The AXF5D4412 maintains active product status with current manufacturing availability, whereas the AXG7440J7 is obsolete. This status difference ensures long-term supply chain viability and continued access to component inventory.

Compliance Alignment: Both components maintain identical RoHS compliance and MSL 1 ratings, ensuring regulatory and environmental compatibility across applications.

Mechanical and Electrical Equivalence: The substitute part matches all critical dimensional and electrical parameters, including pitch, row configuration, mounting type, contact finish, and stacking heights. These parameters determine functional interchangeability within connector assemblies.

Connector Type Consideration: The AXG7440J7 is a socket configuration, while the AXF5D4412 is a receptacle configuration. This distinction reflects complementary connector roles within mated pairs. Selection of the appropriate substitute depends on the specific application requirement—whether a socket or receptacle interface is needed.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the AXG7440J7?

A: The AXG7440J7 is classified as obsolete. The AXF5D4412 provides an active, currently manufactured alternative that maintains all critical electrical and mechanical parameters.

Q: Are the AXG7440J7 and AXF5D4412 mechanically compatible?

A: Both components share identical pitch (0.014" / 0.35mm), row configuration (2 rows), mounting type (surface mount), stacking heights (0.6mm mated, 0.023" / 0.59mm above board), and contact finish (gold). Mechanical compatibility is established through these matching parameters.

Q: What is the difference between the socket and receptacle configurations?

A: The AXG7440J7 is a socket connector (46 positions including 2 power), while the AXF5D4412 is a receptacle connector (44 positions). These represent complementary connector types designed to mate with corresponding plug or header configurations. Selection depends on the specific interface requirement of the application.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the AXG7440J7 and AXF5D4412 are RoHS compliant with MSL 1 (unlimited moisture sensitivity) ratings. They share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What packaging is available for the substitute part?

A: The AXF5D4412 is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: Are there inventory considerations for this substitution?

A: The AXG7440J7 has 1050 pieces in stock as new original inventory. The AXF5D4412 has 772 pieces in stock as new original inventory. Both represent current available stock levels.
