Key Parameters

Substitute Part Grouping Explanation

The Molex 0442624432 qualifies as a direct substitute for the 0442624402 based on the following matching parameters:

• Category: Backplane Connectors
• Series: 44262
• Type: Power
• Pin or Socket: Female Blade Sockets
• Contact Termination: Crimp
• Wire Gauge: 10-12 AWG, 14 AWG
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The primary difference between these parts is the contact finish material and thickness. The substitute part features a gold contact finish at 30.0µin (0.76µm) compared to the tin finish at 80.0µin (2.03µm) in the original part. Both finishes are suitable for power applications within the specified wire gauge range. The substitute part is currently in active production status with available inventory.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0442624432 is the appropriate substitute for the obsolete 0442624402. Both parts maintain identical electrical and mechanical specifications for the 44262 series power connector application, including wire gauge compatibility, termination method, and regulatory compliance. The substitute part is in active production status, ensuring long-term availability and supply chain continuity. The gold contact finish of the substitute part provides enhanced corrosion resistance compared to the tin finish of the original part, which is advantageous for power applications requiring extended service life. Both parts satisfy ROHS3 compliance requirements and carry unlimited moisture sensitivity ratings suitable for standard operating environments.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0442624432 directly replace the 0442624402 in existing designs?

A: Yes. Both parts are female blade sockets within the 44262 series with identical wire gauge ratings (10-12 AWG, 14 AWG), crimp termination, and mechanical dimensions. The contact finish difference does not affect mechanical or electrical compatibility for power applications.

Q: What is the significance of the contact finish difference between these parts?

A: The original part features a tin contact finish at 80.0µin thickness, while the substitute uses a gold finish at 30.0µin thickness. Gold provides superior corrosion resistance and is standard for power connector applications. Both finishes are suitable for the specified wire gauges and application category.

Q: Why is the original part obsolete?

A: The Molex 0442624402 is classified as obsolete, indicating it is no longer in active production. The 0442624432 represents the current active equivalent within the same product series.

Q: Are there packaging differences between these parts?

A: Yes. The original part is supplied in bulk packaging, while the substitute is available in Tape & Reel (TR) format. This packaging difference does not affect component functionality or electrical performance.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the 0442624402 and 0442624432 are ROHS3 compliant and carry identical moisture sensitivity ratings (MSL 1, Unlimited), meeting the same regulatory and environmental requirements.
