AXN450430P Equivalent & Substitute Parts

Part Overview

The AXN450430P 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 AXN450430P is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this connector.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AXN450430P 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 requirement)
• Features: Board guide (mechanical requirement)
• Moisture Sensitivity Level: MSL 1 or better (environmental requirement)

The substitute part AXK6S50437YG meets all mandatory substitution criteria. However, it operates at a different pitch specification (0.020" vs. 0.031"), which represents a significant geometric difference. This pitch change affects PCB layout, mating interface dimensions, and mechanical compatibility with existing connector receptacles designed for the original 0.80mm pitch.

Parameter Comparison

Engineering Selection Recommendations

The AXK6S50437YG is the identified substitute for the obsolete AXN450430P. Both components are manufactured by Panasonic Electric Works and share identical functional characteristics: 50-position headers with outer shroud contacts, gold-plated contacts, board guides, and surface mount configuration.

The AXK6S50437YG offers the advantage of active product status, ensuring ongoing availability and supply chain support. It carries RoHS compliance certification, meeting current environmental and regulatory standards.

The primary geometric difference is the pitch specification: 0.031" (0.80mm) for the original part versus 0.020" (0.50mm) for the substitute. This difference directly impacts PCB footprint design and mating interface compatibility. The substitute also features a reduced height above board (0.130" vs. 0.147"), which may affect clearance considerations in constrained assembly environments.

Selection of the AXK6S50437YG requires verification that the receiving system's PCB layout and mating connector receptacle are compatible with the 0.50mm pitch specification and the modified height profile.

Frequently Asked Questions (FAQ)

Q: Can the AXK6S50437YG be used as a direct replacement for the AXN450430P?

A: Both parts share the same connector type, position count, row configuration, mounting method, and contact finish. However, the pitch difference (0.031" vs. 0.020") means the AXK6S50437YG is not a direct mechanical substitute without PCB redesign. The mating receptacle and board layout must be compatible with the 0.50mm pitch specification.

Q: What is the significance of the pitch difference?

A: Pitch defines the center-to-center distance between adjacent contacts. A change from 0.80mm to 0.50mm results in a more compact connector footprint. This requires corresponding changes to PCB trace routing, via placement, and mating connector design. Existing receptacles designed for 0.80mm pitch will not mate with the 0.50mm pitch header.

Q: Does the height difference affect compatibility?

A: The AXK6S50437YG has a height above board of 0.130" compared to 0.147" for the AXN450430P. This 0.017" reduction may be relevant in applications with limited vertical clearance. Both parts support identical mated stacking heights (4mm, 4.5mm, 7mm).

Q: What is the packaging difference?

A: The AXN450430P 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 operations.

Q: Are there compliance differences between these parts?

A: The AXK6S50437YG is RoHS compliant, meeting current environmental regulations. RoHS status for the AXN450430P is not specified. Both parts carry MSL 1 (Unlimited) moisture sensitivity classification and EAR99 export control designation.

Q: Why is the AXN450430P obsolete?

A: The AXN450430P belongs to the P8 series, which has been superseded by the P5KS series (represented by the AXK6S50437YG). The transition reflects product line consolidation and the adoption of finer pitch specifications in modern connector design.
