AXN400430S Equivalent & Substitute Parts

Part Overview

The AXN400430S 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 AXN400430S 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 eligibility for the AXN400430S 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)
• Mated Stacking Heights: Compatibility with 4mm, 4.5mm, or 7mm stacking heights (mechanical interface)

The substitute part AXK6S00437YG meets the core functional and mechanical requirements. However, it differs in pitch specification (0.020" vs. 0.031"), which represents a significant design parameter change. This difference affects PCB layout, contact spacing, and overall connector footprint. Substitution is valid only when the receiving system design accommodates the modified pitch specification and resulting dimensional changes.

Parameter Comparison

Engineering Selection Recommendations

The AXK6S00437YG is an active product from the same manufacturer, providing supply chain continuity for the obsolete AXN400430S. Both components share identical MSL ratings and mated stacking height compatibility.

The primary design consideration is the pitch change from 0.031" to 0.020". This modification requires PCB layout revision to accommodate the reduced contact spacing. The substitute part also exhibits a reduced height above board (0.130" versus 0.146"), which may affect clearance in constrained assembly environments.

Selection of AXK6S00437YG is appropriate when PCB redesign is feasible and the tighter pitch specification aligns with updated design requirements. The active product status ensures long-term availability and supply reliability compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can AXK6S00437YG be used as a direct drop-in replacement for AXN400430S?

A: No. The pitch difference (0.020" versus 0.031") requires PCB layout modification. Direct substitution without design changes will result in contact misalignment and connector failure.

Q: What is the significance of the pitch specification change?

A: Pitch defines the center-to-center distance between adjacent contacts. The 0.020" pitch in AXK6S00437YG results in a more compact connector footprint compared to the 0.031" pitch of AXN400430S. This affects PCB trace routing, contact density, and overall assembly dimensions.

Q: Are the mated stacking heights compatible between both parts?

A: Yes. Both AXN400430S and AXK6S00437YG support identical mated stacking heights of 4mm, 4.5mm, and 7mm, ensuring compatibility with mating connectors designed for these specifications.

Q: What is the impact of the height above board difference?

A: AXK6S00437YG has a height above board of 0.130" compared to 0.146" for AXN400430S. This 0.016" reduction may affect clearance in applications with limited vertical space above the PCB. Verify clearance requirements in your specific assembly environment.

Q: Why is AXK6S00437YG recommended despite the pitch change?

A: AXK6S00437YG is an active product with guaranteed long-term availability, whereas AXN400430S is obsolete. Both components are manufactured by Panasonic Electric Works, share identical contact finish and MSL ratings, and support the same mated stacking heights. The pitch change is a design parameter that can be accommodated through PCB revision.

Q: What packaging format is available for AXK6S00437YG?

A: AXK6S00437YG is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.
