AXN340C038P Equivalent & Substitute Parts

Part Overview

The AXN340C038P is a 40-position rectangular connector socket manufactured by Panasonic Electric Works, designed for surface mount applications with center strip contacts and gold plating. This component belongs to the P8 series and features a 0.031" (0.80mm) pitch configuration with dual-row layout.

The AXN340C038P is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AXN340C038P is determined by the following critical parameters:

• Connector Type: Socket, Center Strip Contacts (must match)
• Number of Positions: 40 (must match)
• Number of Rows: 2 (must match)
• Mounting Type: Surface Mount (must match)
• Contact Finish: Gold (must match)
• Moisture Sensitivity Level: 1 (Unlimited) (must match)

The substitute part AXK5S40047YG meets all mandatory matching criteria. However, this substitute introduces a pitch change from 0.031" (0.80mm) to 0.020" (0.50mm), which represents a significant dimensional modification. This pitch difference affects PCB layout, mating interface compatibility, and physical spacing requirements. The substitute also exhibits increased height above board (0.120" vs. 0.087") and modified mated stacking heights (4mm, 5mm, 6mm vs. 3mm, 4mm, 5mm).

Parameter Comparison

Engineering Selection Recommendations

The AXK5S40047YG is the identified substitute for the obsolete AXN340C038P. Selection of this substitute requires evaluation of the following factors:

Product Status: The substitute part is active and currently in production, ensuring ongoing availability and supply chain continuity compared to the obsolete main part.

Compliance: The substitute is RoHS Compliant, whereas RoHS status is not specified for the main part. Both parts carry identical ECCN (EAR99) and HTSUS classifications.

Dimensional Compatibility: The substitute exhibits a reduced pitch (0.020" vs. 0.031"), increased height above board (0.120" vs. 0.087"), and modified mated stacking heights. These dimensional changes necessitate PCB redesign and mechanical re-evaluation of the mating interface.

Electrical Equivalence: Both parts maintain identical contact finish (gold), connector type (socket, center strip contacts), position count (40), and row configuration (2 rows), supporting functional electrical equivalence within the constraints of the dimensional modifications.

Frequently Asked Questions (FAQ)

Q: Can AXK5S40047YG be used as a direct drop-in replacement for AXN340C038P?

A: No. While both connectors share the same position count, row configuration, and contact finish, the pitch difference (0.031" vs. 0.020") and increased height above board (0.087" vs. 0.120") require PCB layout modifications and mechanical re-evaluation. Direct substitution without design changes is not possible.

Q: What is the significance of the pitch change from 0.031" to 0.020"?

A: Pitch defines the center-to-center spacing between adjacent contacts. A reduction from 0.031" to 0.020" results in a more compact connector footprint. This change affects PCB trace routing, component placement, and the physical dimensions of the mating connector interface. Existing PCB designs must be redesigned to accommodate the new pitch specification.

Q: Are there packaging differences between the main part and substitute?

A: Yes. The main part (AXN340C038P) packaging is not specified in the provided data. The substitute part (AXK5S40047YG) is supplied in Tape & Reel (TR) packaging, which is standard for surface mount production environments.

Q: Does the substitute part meet RoHS requirements?

A: Yes. The AXK5S40047YG is RoHS Compliant. RoHS status for the main part is not specified. If RoHS compliance is a design requirement, the substitute part satisfies this criterion.

Q: What are the mated stacking height implications?

A: The main part supports mated stacking heights of 3mm, 4mm, and 5mm. The substitute supports 4mm, 5mm, and 6mm. If your application requires a 3mm stacking height, the substitute cannot fulfill this requirement. Applications using 4mm or 5mm stacking heights are compatible with both parts.

Q: Is the substitute part currently available?

A: Yes. The substitute part (AXK5S40047YG) is active and has 1601 pieces in stock as new original inventory, ensuring supply availability compared to the obsolete main part.
