AXG8440J4 Equivalent & Substitute Parts

Part Overview

The AXG8440J4 is a 46-position rectangular connector plug manufactured by Panasonic Electric Works, featuring outer shroud contacts and surface mount gold plating. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. The connector is designed for applications requiring high-density interconnection with reliable solder retention and gold contact finish for enhanced signal integrity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AXG8440J4 is determined by alignment of the following critical parameters:

• Pitch specification: 0.014" (0.35mm) — ensures mechanical and electrical compatibility with mating connectors
• Mounting type: Surface Mount — maintains PCB assembly process compatibility
• Contact finish: Gold — preserves signal integrity and corrosion resistance
• Row configuration: 2 rows — defines physical footprint and contact arrangement
• Mated stacking height: 0.6mm — ensures proper mating depth and mechanical fit
• RoHS compliance: Required for regulatory alignment

The substitute part AXF6D4412 maintains these core parameters. However, the primary distinction is the connector type: AXG8440J4 is a plug configuration, while AXF6D4412 is a header configuration. This difference requires careful evaluation of the mating interface in the target application.

Parameter Comparison

Engineering Selection Recommendations

The AXF6D4412 is an active product with current manufacturing support, providing supply chain continuity for the obsolete AXG8440J4. Both components share identical electrical and mechanical specifications including pitch, mounting type, contact finish, stacking height, and compliance certifications.

The primary design consideration is the connector type transition from plug to header. This substitution is valid only when the mating interface in the target application is compatible with a header configuration. If the application requires a plug connector, alternative solutions within the Panasonic A35 series must be evaluated.

The AXF6D4412 is supplied in Tape & Reel packaging, suitable for automated assembly processes. Both components maintain RoHS compliance and unlimited moisture sensitivity rating, ensuring regulatory and environmental compatibility.

Frequently Asked Questions (FAQ)

Q: Can AXF6D4412 directly replace AXG8440J4 in existing designs?

A: Direct replacement is possible only if the mating interface accepts a header connector. The AXG8440J4 is a plug; the AXF6D4412 is a header. The connector type must match the receptacle in your application.

Q: What is the difference in position count between these parts?

A: The AXG8440J4 has 46 positions (44 signal + 2 power), while the AXF6D4412 has 44 positions. If your design requires the 2 dedicated power positions, alternative solutions must be evaluated.

Q: Are the pitch and row configurations identical?

A: Yes. Both components use 0.014" (0.35mm) pitch with 2-row configuration, ensuring mechanical compatibility with mating connectors designed for this specification.

Q: What is the significance of the product status difference?

A: The AXG8440J4 is obsolete with no ongoing manufacturing. The AXF6D4412 is active with current production, ensuring long-term supply availability and technical support.

Q: Are both components RoHS compliant?

A: Yes. Both the AXG8440J4 and AXF6D4412 are RoHS compliant with MSL rating of 1 (unlimited moisture sensitivity), meeting regulatory requirements for lead-free assembly.

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

A: The AXF6D4412 is supplied in Tape & Reel (TR) format, optimized for automated pick-and-place assembly processes.
