Key Parameters

Substitute Part Grouping Explanation

Substitution of the AXT438164 is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Header with center strip contacts, 38 positions arranged in 2 rows
• Electrical Interface: 0.016" (0.40mm) pitch contact spacing
• Physical Mounting: Surface mount technology with identical board height of 0.049" (1.25mm)
• Contact Properties: Gold finish with solder retention capability
• Stacking Compatibility: Mated stacking heights of 1.5mm and 2.5mm
• Environmental Classification: MSL 1 rating for unlimited moisture exposure

The AXT438124 satisfies all these parameters while maintaining the same P4S series designation and base product number AXT438. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The AXT438124 is the direct functional equivalent for the obsolete AXT438164. Both components share identical electrical and mechanical specifications within the P4S series, ensuring pin-for-pin compatibility and identical PCB footprint requirements.
