AXK780347A Equivalent & Substitute Parts

Part Overview

The AXK780347A is an 80-position rectangular connector socket manufactured by Panasonic Electric Works, designed for surface mount applications. This connector features a center strip with outer edge contacts configuration and gold plating for reliable signal transmission. The part is classified as "Not For New Designs," indicating it has been superseded in the product lifecycle. Finding equivalent or substitute parts is necessary for maintenance, repair, and legacy system support where this connector type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AXK780347A must maintain compatibility across the following critical parameters:

• Number of Positions: 80 positions (electrical requirement)
• Pitch: 0.016" (0.40mm) (mechanical interchangeability)
• Number of Rows: 2 rows (physical layout)
• Mounting Type: Surface Mount (assembly process compatibility)
• Contact Finish: Gold (signal integrity and corrosion resistance)
• Mated Stacking Heights: 2.5mm, 3mm (mechanical fit)
• RoHS Compliance: Required for regulatory alignment
• Moisture Sensitivity Level: 1 (Unlimited) (handling and storage compatibility)

The primary difference between the main part and substitute parts lies in the connector type configuration (center strip with outer edge contacts versus outer shroud contacts). This distinction affects the mechanical interface design but does not prevent functional substitution when the mating connector is compatible with the alternative contact arrangement.

Parameter Comparison

Engineering Selection Recommendations

The AXT380224A serves as a functional substitute for the AXK780347A based on the following criteria:

Electrical Compatibility: Both parts maintain identical position count (80), pitch (0.016"/0.40mm), row configuration (2), and contact finish (gold), ensuring electrical signal integrity and connector mating compatibility with appropriate mating connectors.

Mechanical Compatibility: Both parts share identical mated stacking heights (2.5mm, 3mm) and nearly identical height above board measurements (0.095" versus 0.096"), permitting direct board-level substitution without PCB redesign.

Regulatory Compliance: Both parts are RoHS Compliant and carry identical Moisture Sensitivity Level (MSL 1 - Unlimited), meeting environmental and handling requirements.

Product Lifecycle Status: The AXT380224A is classified as Active, whereas the AXK780347A is Not For New Designs. For legacy system support and repair applications, the AXT380224A provides continued availability and supply chain stability.

Primary Consideration: The connector type differs (center strip with outer edge contacts versus outer shroud contacts). Substitution is valid only when the mating connector on the cable or complementary assembly is compatible with the outer shroud contact configuration of the AXT380224A.

Frequently Asked Questions (FAQ)

Q: Can the AXT380224A directly replace the AXK780347A on existing PCBs?

A: Direct PCB-level replacement is possible if the footprint accommodates the outer shroud contact configuration of the AXT380224A. The height above board difference (0.001") is negligible for most applications. Verification of mating connector compatibility is required.

Q: What is the primary difference between these two parts?

A: The connector type configuration differs. The AXK780347A uses a center strip with outer edge contacts design, while the AXT380224A uses an outer shroud contacts design. Both are 80-position, 0.016" pitch surface mount sockets with gold plating.

Q: Are both parts RoHS Compliant?

A: Yes, both the AXK780347A and AXT380224A are RoHS Compliant and carry identical Moisture Sensitivity Level (MSL 1 - Unlimited).

Q: Why is the AXK780347A marked "Not For New Designs"?

A: This designation indicates the part has been superseded in the manufacturer's product lifecycle. The AXT380224A (Active status) represents the current generation equivalent within the P4 series family.

Q: Do the mated stacking heights match between these parts?

A: Yes, both parts support identical mated stacking heights of 2.5mm and 3mm, ensuring mechanical compatibility in mating applications.

Q: What is the significance of the Series designation (P4 versus P4S)?

A: The Series designation indicates product line variants. P4S denotes the shrouded contact variant of the P4 series. Both maintain the same electrical and mechanical specifications for position count, pitch, and mounting type.
