Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1827585-1 be used as a direct replacement for the Molex 0443801016?

A: Yes. The TE Connectivity part matches all critical parameters including connector type, pin configuration, orientation, shielding, contact materials, and operating temperature range. No design modifications are required for direct substitution.

Q: Are there any differences in housing material between these parts?

A: The Molex 0443801016 uses Polyamide (PA) Nylon with glass fill, while the TE Connectivity 1827585-1 uses Thermoplastic material. Both materials provide equivalent mechanical and electrical performance for this connector class.

Q: What is the significance of the board guide and light pipe features?

A: These features ensure proper connector alignment during assembly and provide visual indication of connection status. Both substitute parts retain these features.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the Molex 0443801016 and TE Connectivity 1827585-1 are RoHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: What is the difference in packaging between these parts?

A: The Molex part does not specify packaging format, while the TE Connectivity substitute is supplied in Tray packaging. This does not affect functional compatibility.

Q: Are the contact finish specifications identical?

A: Yes. Both parts feature gold-plated phosphor bronze contacts with 50.0µin (1.27µm) finish thickness, ensuring equivalent electrical performance and corrosion resistance.
