AXN350038P Equivalent & Substitute Parts

Part Overview

The AXN350038P is a 50-position rectangular connector socket manufactured by Panasonic Electric Works, designed for surface mount applications with center strip contacts and gold plating. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing production and maintenance applications. The connector features a 0.031" (0.80mm) pitch configuration with dual-row arrangement and board guide features, operating at unlimited moisture sensitivity level (MSL 1).

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AXN350038P is determined by the following critical parameters:

Mandatory Matching Criteria:

• Connector type: Socket, center strip contacts
• Number of positions: 50
• Number of rows: 2
• Mounting type: Surface mount
• Contact finish: Gold
• Manufacturer: Panasonic Electric Works

Allowable Variation Parameters:

• Pitch: Different pitch values (0.020" vs. 0.031") represent distinct mechanical and electrical footprints and are not interchangeable without PCB redesign
• Height above board: Variation acceptable within design envelope constraints
• Mated stacking heights: Variation acceptable based on mating connector specifications
• Product status: Active status preferred for ongoing availability
• Packaging format: Variation acceptable (bulk vs. tape & reel)

The substitute part AXK5S50037YG shares the core functional characteristics (50-position socket, dual-row, surface mount, gold contacts) but operates at a different pitch specification (0.020" vs. 0.031"), which represents a distinct product line within the Panasonic rectangular connector portfolio.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Pitch 0.031"): No alternative parts are listed with identical 0.031" pitch specification. The AXN350038P remains the only documented option for this specific pitch configuration within the provided dataset.

For Functional Equivalence (Different Pitch 0.020"): The AXK5S50037YG provides functional equivalence in connector topology (50-position, dual-row, surface mount socket with gold contacts) but operates at 0.020" pitch. Selection of this substitute requires PCB redesign to accommodate the different pitch footprint and increased height above board (3.05mm vs. 2.20mm).

Product Status Consideration: The AXK5S50037YG maintains active product status with RoHS compliance certification, providing superior long-term availability and regulatory alignment compared to the obsolete AXN350038P.

Frequently Asked Questions (FAQ)

Q: Can AXK5S50037YG be used as a direct drop-in replacement for AXN350038P?

A: No. While both connectors share identical position count, row configuration, and mounting type, the pitch difference (0.020" vs. 0.031") requires PCB footprint modification. Direct substitution without layout redesign will result in mechanical misalignment.

Q: What is the significance of pitch in connector selection?

A: Pitch defines the center-to-center spacing between adjacent contact positions. This dimension directly determines PCB pad layout and cannot be altered without complete circuit board redesign. Pitch mismatch prevents proper connector seating.

Q: Are both connectors suitable for the same environmental conditions?

A: Both connectors carry MSL 1 (Unlimited) moisture sensitivity rating, indicating equivalent performance in standard industrial environments. The AXK5S50037YG additionally carries RoHS compliance certification.

Q: What packaging formats are available?

A: The AXN350038P is supplied in standard packaging format. The AXK5S50037YG is supplied in Tape & Reel (TR) format, suitable for automated assembly processes.

Q: How do the height specifications affect PCB design?

A: The AXN350038P provides 0.087" (2.20mm) height above board, while AXK5S50037YG provides 0.120" (3.05mm). This difference impacts clearance calculations for adjacent components and enclosure design. Mated stacking heights also differ (3-5mm vs. 4-6mm), affecting connector stack planning.
