Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AXN350C038S is determined by the following critical parameters:

• Connector Type: Socket with center strip contacts (functional requirement)
• Number of Positions: 50 positions (pin count requirement)
• Number of Rows: 2 rows (contact arrangement requirement)
• Mounting Type: Surface mount (assembly process requirement)
• Contact Finish: Gold plating (electrical performance and corrosion resistance)
• Manufacturer: Panasonic Electric Works (supply chain consistency)

The substitute part AXK5S50037YG meets the core functional requirements of connector type, position count, row configuration, mounting method, and contact finish. However, this substitute introduces variations in pitch specification (0.020" vs. 0.031"), height above board (0.120" vs. 0.087"), and mated stacking heights, which may require PCB layout and mechanical design verification.

Parameter Comparison

Engineering Selection Recommendations

The AXK5S50037YG is an active-status substitute from the same manufacturer, providing supply continuity for the obsolete AXN350C038S. The substitute maintains functional equivalence in connector type, position count, row configuration, and contact finish specifications.

The AXK5S50037YG carries RoHS compliance certification, whereas the main part does not specify RoHS status. This compliance advantage supports regulatory requirements in applications subject to RoHS directives.

Dimensional differences exist between the two parts: the substitute exhibits a finer pitch (0.020" vs. 0.031"), increased height above board (0.120" vs. 0.087"), and different mated stacking height ranges (4–6mm vs. 3–5mm). These variations require verification against PCB layout constraints, enclosure clearances, and mating component specifications before implementation.

Both parts maintain MSL 1 classification, indicating equivalent moisture sensitivity handling requirements.

Frequently Asked Questions (FAQ)

Q: Can AXK5S50037YG directly replace AXN350C038S without PCB modification?

A: Direct replacement without PCB modification is not assured. The substitute features a different pitch (0.020" vs. 0.031"), which affects pad spacing and trace routing. PCB layout verification is required.

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

A: The main difference is pitch specification. AXN350C038S uses 0.031" (0.80mm) pitch, while AXK5S50037YG uses 0.020" (0.50mm) pitch. This affects PCB footprint design and component density.

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

A: Both parts carry MSL 1 classification, indicating equivalent moisture sensitivity levels and unlimited shelf life under standard storage conditions.

Q: Does the substitute offer any compliance advantages?

A: Yes. AXK5S50037YG is RoHS compliant, whereas the main part does not specify RoHS status. This is advantageous for applications requiring regulatory compliance.

Q: What packaging format is available for the substitute?

A: AXK5S50037YG is supplied in Tape & Reel (TR) format, suitable for automated assembly processes.

Q: Are both parts manufactured by the same company?

A: Yes. Both AXN350C038S and AXK5S50037YG are manufactured by Panasonic Electric Works, ensuring consistent quality standards and supply chain reliability.
