Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AXT332124 is determined by strict alignment of the following electrical and mechanical parameters:

• Connector Type: Socket configuration with outer shroud contacts
• Position Count: 32 positions
• Pitch Specification: 0.016" (0.40mm) contact spacing
• Row Configuration: 2-row arrangement
• Mounting Technology: Surface mount (SMD)
• Contact Material: Gold plating for signal integrity and corrosion resistance
• Solder Retention: Required feature for manufacturing reliability
• Compliance Standards: RoHS and MSL 1 rating

The identified substitute part 5015313210 (Molex SlimStack 501531 series) satisfies all critical substitution criteria. While this part functions as a plug connector rather than a socket, it maintains mechanical and electrical compatibility within a mated pair assembly, sharing identical pitch, position count, row configuration, mounting type, contact finish, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the AXT332124 and 5015313210 are classified as obsolete products. Selection between these components depends on application requirements:

AXT332124 Selection: Use when socket connectors are specified in the original design or when the mating interface requires a 1.5mm stacking height.

5015313210 Selection: Use when plug connectors are required or when the reduced height profile (1.3mm stacking height, 0.041" above board) provides design advantages. This part offers ROHS3 compliance, representing a more recent regulatory standard than RoHS.

Both parts maintain identical electrical characteristics through 32-position, 0.40mm pitch configuration with gold contact finish and solder retention features. MSL 1 rating on both parts ensures compatibility with standard storage and handling protocols.

Frequently Asked Questions (FAQ)

Q: Can the 5015313210 directly replace the AXT332124 in existing assemblies?

A: Direct replacement requires design verification. The 5015313210 is a plug connector while the AXT332124 is a socket. Both parts are compatible when used as mated pairs. Height differences (1.45mm vs. 1.05mm above board) must be evaluated against PCB layout constraints.

Q: What does the 0.016" (0.40mm) pitch specification mean?

A: Pitch defines the center-to-center distance between adjacent contact positions. Both parts maintain 0.016" spacing, ensuring mechanical and electrical compatibility within the 32-position, 2-row configuration.

Q: Are there compliance differences between these parts?

A: The AXT332124 carries RoHS compliance while the 5015313210 carries ROHS3 compliance. Both parts are MSL 1 rated and REACH unaffected. ROHS3 represents updated regulatory requirements; either certification satisfies current environmental standards.

Q: What is the significance of the gold contact finish thickness specification?

A: The 5015313210 specifies 8.00µin (0.203µm) gold plating thickness. The AXT332124 does not provide this specification. Both parts use gold finish for corrosion resistance and signal integrity. Thickness differences do not affect substitution eligibility for standard applications.

Q: How do the stacking heights affect connector selection?

A: Mated stacking height (1.5mm vs. 1.3mm) and height above board (0.057" vs. 0.041") determine overall assembly profile. Applications with height constraints may require the 5015313210. Verify PCB clearance and enclosure dimensions before selection.

Q: What is solder retention and why is it important?

A: Solder retention is a mechanical feature that holds solder in place during reflow processes, preventing solder bridges and ensuring reliable connections. Both parts include this feature, supporting standard SMD manufacturing processes.
