AXN400C330S Equivalent & Substitute Parts

Part Overview

The AXN400C330S is a 100-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 AXN400C330S 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 for the AXN400C330S is determined by the following critical parameters:

• Connector Type: Header with outer shroud contacts (functional requirement)
• Number of Positions: 100 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 AXK6S00437YG shares the same connector type, position count, row configuration, mounting method, contact finish, and manufacturer. However, it operates at a different pitch specification (0.020" versus 0.031"), which represents a fundamental change in the connector's physical footprint and electrical spacing. This difference requires careful evaluation during component selection.

Parameter Comparison

Engineering Selection Recommendations

The AXK6S00437YG is an active product from the same manufacturer with current production status and RoHS compliance certification. This part maintains functional equivalence in connector type, position count, row configuration, and contact finish.

The primary distinction is the pitch specification: AXK6S00437YG operates at 0.020" (0.50mm) pitch compared to the original 0.031" (0.80mm). This change directly affects PCB layout, footprint dimensions, and physical spacing between contacts. Height above board and mated stacking heights also differ accordingly.

Selection of AXK6S00437YG requires confirmation that the receiving system's PCB design, mating connector, and mechanical envelope accommodate the tighter pitch and increased height specifications. The active product status and RoHS compliance of AXK6S00437YG provide advantages for new designs and long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can AXK6S00437YG directly replace AXN400C330S without PCB modification?

A: No. The pitch difference (0.031" to 0.020") requires PCB footprint redesign. The increased height above board (0.107" to 0.130") may affect mechanical clearance in confined spaces. Direct substitution without layout verification is not possible.

Q: What does the pitch specification mean for compatibility?

A: Pitch defines the center-to-center distance between adjacent contacts. A smaller pitch (0.020") results in higher contact density and reduced overall connector width for the same 100-position count. The mating connector must match this pitch specification exactly.

Q: Why is AXN400C330S listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. AXK6S00437YG, as an active product, represents the current generation equivalent from Panasonic Electric Works.

Q: Are both parts RoHS compliant?

A: AXK6S00437YG is explicitly RoHS compliant. RoHS status for AXN400C330S is not specified in available documentation.

Q: What is the significance of MSL 1 (Unlimited)?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling, simplifying logistics and inventory management for both parts.

Q: Does packaging format affect electrical performance?

A: No. AXK6S00437YG is supplied in Tape & Reel (TR) format for automated assembly. Packaging affects handling and production efficiency but not electrical or mechanical function.
