AXN450330J Equivalent & Substitute Parts

Part Overview

The AXN450330J is a 50-position rectangular connector header manufactured by Panasonic Electric Works, designed for surface mount applications with outer shroud contacts and gold plating. This component belongs to the P8 series and features a 0.031" (0.80mm) pitch configuration across 2 rows.

The AXN450330J 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.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AXN450330J is determined by the following critical parameters:

• Connector Type: Header with outer shroud contacts (functional requirement)
• Number of Positions: 50 positions (electrical requirement)
• Number of Rows: 2 rows (physical layout requirement)
• Mounting Type: Surface mount (assembly requirement)
• Contact Finish: Gold plating (electrical performance and reliability)
• Manufacturer: Panasonic Electric Works (supply chain consistency)

The substitute part AXK6S50437YG shares the same connector type, position count, row configuration, mounting method, and contact finish. However, it differs in pitch specification (0.020" vs. 0.031"), series designation (P5KS vs. P8), and physical dimensions. These differences indicate that while both parts serve the same functional role as 50-position surface mount headers with gold contacts, they are not pin-compatible and cannot be used interchangeably without PCB redesign.

Parameter Comparison

Engineering Selection Recommendations

The AXK6S50437YG is an active product from Panasonic Electric Works with current inventory availability (3080 pcs) and RoHS compliance certification. The AXN450330J is obsolete with limited remaining stock (995 pcs).

Selection between these parts depends on design constraints:

• If the original 0.031" (0.80mm) pitch and 2.72mm height are critical to existing PCB layouts, the AXN450330J may be used while stock remains available.
• If design flexibility exists, the AXK6S50437YG offers the advantage of active product status, higher inventory levels, RoHS compliance, and long-term supply chain support. This substitution requires PCB redesign to accommodate the 0.020" (0.50mm) pitch and 3.30mm height specifications.

Both parts share identical MSL ratings and are manufactured by the same supplier, ensuring equivalent environmental handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can AXK6S50437YG be used as a direct replacement for AXN450330J without PCB modification?

A: No. The pitch difference (0.031" vs. 0.020") and height difference (2.72mm vs. 3.30mm) make these parts physically incompatible. Direct substitution requires PCB redesign and footprint modification.

Q: What is the primary difference between these two connector headers?

A: The main difference is pitch specification. The AXN450330J uses 0.031" (0.80mm) pitch, while the AXK6S50437YG uses 0.020" (0.50mm) pitch. This affects the physical spacing of contact positions and overall connector dimensions.

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

A: Yes. Both parts have identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited), indicating equivalent environmental handling and storage requirements.

Q: What is the packaging difference between these parts?

A: The AXN450330J packaging is not specified in available data. The AXK6S50437YG is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly.

Q: Does the AXK6S50437YG offer any compliance advantages?

A: Yes. The AXK6S50437YG is RoHS Compliant, while the AXN450330J RoHS status is not specified. For applications requiring RoHS certification, the AXK6S50437YG is the appropriate choice.

Q: Why is the AXN450330J classified as obsolete?

A: The AXN450330J belongs to the P8 series, which has been superseded by newer product lines such as the P5KS series (represented by AXK6S50437YG). Panasonic Electric Works has transitioned manufacturing focus to active product lines with improved specifications and compliance certifications.
