Molex 0393530004 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Molex 0393530004 is a 4-position vertical terminal block header with 4.6mm pitch, designed for through-hole solder mounting applications. This component features male pins with 4-side shrouding and operates at 300V UL with a 10A current rating. The part is classified as obsolete, making equivalent substitute components necessary for ongoing design support and procurement continuity. Substitute parts must maintain electrical compatibility (voltage, current, pitch) and mechanical interchangeability (mounting type, pin configuration, shrouding design).

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0393530004 is determined by strict adherence to the following core parameters:

Electrical Compatibility: Voltage rating (300V UL minimum), current rating (10A minimum), contact material (conductive properties)
Mechanical Compatibility: 4-position configuration, 4.6mm pitch, vertical orientation, through-hole mounting, male pin shrouded design
Termination: Solder termination required
Regulatory Compliance: ROHS3 compliance and EAR99 classification

All listed substitute parts meet these criteria. Variations in housing material composition, contact tail length, insulation height, and operating temperature ranges do not affect functional substitution within the specified electrical and mechanical constraints.

Engineering Selection Recommendations

Molex 0395011004 (Direct Molex Substitute): Active product status with ROHS3 compliance. Maintains identical pitch, position count, and shrouding configuration. Current rating of 8A is within acceptable range for applications not exceeding this threshold. Polyamide PA66 housing provides improved thermal stability compared to the original PA46 composition. Operating temperature range of -40°C to 105°C covers standard industrial applications.

TE Connectivity 284514-4 (Buchanan Series): Active product with highest current rating (11A) among substitutes, providing design margin for high-current applications. Phosphor bronze contact material offers enhanced durability and contact resistance characteristics. ROHS3 compliant with -40°C to 110°C operating range. Green housing color distinguishes this variant in assembly environments.

Assmann A-TB350-OQ04CV: Active product with current rating matching the original specification (10A). Thermoplastic housing material with -30°C to 105°C operating range. ROHS3 compliant. Green housing color. Suitable for applications requiring exact current specification match.

Amphenol ELXH04500 (ELXH Series): Active product with highest current rating (12A) and highest single operating temperature specification (125°C). Polyamide PA46 housing matches original material composition. ROHS3 compliant. Black housing color matches original aesthetic. Tray packaging differs from bulk alternatives.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a lower current rating than the original 10A specification?

A: Molex 0395011004 is rated at 8A. Substitution is permissible only if your circuit design operates below 8A. Verify actual circuit current requirements before selection.

Q: Are all substitute parts pin-compatible with the original Molex 0393530004?

A: Yes. All substitute parts maintain 4-position configuration, 4.6mm pitch, vertical orientation, and through-hole solder termination. Mechanical interchangeability is confirmed across all listed alternatives.

Q: What is the difference between PA46 and PA66 housing materials?

A: Both are polyamide materials suitable for this application. PA66 (used in Molex 0395011004) offers slightly improved thermal stability. PA46 (used in original and Amphenol ELXH04500) provides equivalent electrical performance for standard operating conditions.

Q: Does contact material (Brass vs. Phosphor Bronze) affect substitution eligibility?

A: Both materials are acceptable for this application class. Phosphor bronze (TE Connectivity 284514-4) provides enhanced contact durability in high-cycle mating applications. Brass (original and most substitutes) is standard for general-purpose terminal block applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitutes carry ROHS3 compliance certification, meeting current environmental regulations.

Q: What packaging options are available?

A: Molex 0395011004, TE Connectivity 284514-4, and Assmann A-TB350-OQ04CV are supplied in bulk packaging. Amphenol ELXH04500 is supplied in tray packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Can I mix substitute parts in the same design?

A: All substitute parts are electrically and mechanically compatible. However, maintaining single-source parts within a design simplifies procurement, documentation, and supply chain management.
