Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AXN400330S is determined by the following critical parameters:

• Connector Type: Must be Header with Outer Shroud Contacts
• Number of Positions: Must be 100
• Number of Rows: Must be 2
• Mounting Type: Must be Surface Mount
• Contact Finish: Must be Gold
• Features: Must include Board Guide
• Moisture Sensitivity Level: Must be MSL 1 or equivalent

The substitute part AXK6S00437YG meets the functional requirements of connector type, position count, row configuration, mounting method, contact finish, and board guide feature. However, this substitute introduces a critical difference in pitch specification: 0.020" (0.50mm) versus the original 0.031" (0.80mm). This pitch difference affects physical footprint, mating interface compatibility, and PCB layout requirements. Substitution is valid only when the receiving system design accommodates the modified pitch specification and corresponding dimensional changes.

Parameter Comparison

Engineering Selection Recommendations

The AXN400330S is obsolete, making AXK6S00437YG the active alternative from Panasonic Electric Works. Both components share identical connector architecture, position count, row configuration, mounting method, and contact finish specifications.

The AXK6S00437YG provides RoHS compliance certification, which may be required for new designs or regulatory compliance mandates. The substitute maintains MSL 1 rating, ensuring equivalent moisture handling characteristics.

The primary design consideration is pitch modification from 0.031" (0.80mm) to 0.020" (0.50mm). This change affects PCB footprint dimensions, contact spacing, and mating interface geometry. Selection of AXK6S00437YG requires verification that the receiving system design accommodates these dimensional changes and that mating connectors are compatible with the 0.020" pitch specification.

Frequently Asked Questions (FAQ)

Q: Can AXK6S00437YG directly replace AXN400330S without PCB redesign?

A: Direct replacement without PCB modification is not possible. The pitch difference (0.031" versus 0.020") requires footprint redesign. Mating connectors must also be compatible with the 0.020" pitch specification.

Q: What is the significance of the pitch change?

A: Pitch defines the center-to-center distance between adjacent contacts. The reduction from 0.031" to 0.020" decreases the overall connector footprint, affects contact spacing on the PCB, and requires compatible mating connectors designed for 0.020" pitch.

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

A: Both components carry MSL 1 (Unlimited) ratings, indicating equivalent moisture sensitivity performance. The AXK6S00437YG additionally provides RoHS compliance certification.

Q: What packaging formats are available?

A: AXN400330S packaging is not specified in available data. AXK6S00437YG is supplied in Tape & Reel (TR) format.

Q: How do the stacking heights differ?

A: AXN400330S offers mated stacking heights of 3mm, 4.6mm, and 6mm with 0.107" (2.72mm) height above board. AXK6S00437YG provides 4mm, 4.5mm, and 7mm stacking heights with 0.130" (3.30mm) height above board. These differences reflect the pitch modification and must be evaluated against system space constraints.
