Molex 0393530003 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Molex 0393530003 is a 3-position vertical terminal block header with 4.6mm pitch, designed for through-hole solder mounting applications. This component features shrouded male pins and is rated for 10A at 300V UL. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain electrical compatibility (voltage, current ratings) and mechanical interchangeability (pitch, orientation, mounting style) while meeting current manufacturing standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters:

• Electrical Compatibility: Voltage rating (300V UL minimum), current rating (equal to or greater than 10A UL)
• Mechanical Compatibility: 3 positions, 0.138" (4.6mm) pitch, vertical orientation, through-hole solder mounting
• Connector Type: Male pins with 4-side shrouding
• Contact Material: Brass with tin mating finish

All three substitute parts meet these core requirements. Variations in housing material, operating temperature range, and color do not affect functional substitution for this application category.

Parameter Comparison

Engineering Selection Recommendations

Molex 0395011003 (Eurostyle ESE 39501): Active product status with ROHS3 compliance. Current rating of 8A is below the original 10A specification; suitable for applications operating at or below 8A. Recommended for direct replacement in low-current designs or where component availability from the original manufacturer is prioritized.

Amphenol PCD ELXH03500 (ELXH Series): Active product with RoHS compliance. Current rating of 12A exceeds original specification, providing margin for higher-current applications. Operating temperature maximum of 125°C is lower than the original 140°C. Suitable for general-purpose substitution where higher current capacity is beneficial.

American Electrical H-040-35003: Active product with ROHS3 compliance. Current rating of 12A and extended operating temperature range (-55°C to 105°C) provide broader environmental tolerance. Housing color is green rather than black. Suitable for applications requiring extended temperature range or higher current capacity.

All three substitutes are active products with current manufacturing support and compliance certifications, addressing the obsolescence of the original part.

Frequently Asked Questions (FAQ)

Q: Can I use part 0395011003 as a direct replacement for 0393530003?

A: Mechanically and electrically, yes, with the caveat that the current rating is reduced from 10A to 8A. If your application draws 8A or less, this part is fully compatible. If your design requires the full 10A capacity, consider ELXH03500 or H-040-35003.

Q: What is the significance of the different housing materials (PA46 vs PA66)?

A: Both materials are polyamide-based and suitable for this connector class. PA66 (nylon 6/6) offers slightly different thermal and mechanical properties compared to PA46 (nylon 4/6), but both meet the electrical and mechanical requirements for terminal block headers at 4.6mm pitch.

Q: Does the color difference (black vs green) affect functionality?

A: No. Color is a cosmetic attribute and does not affect electrical or mechanical performance. The green housing of H-040-35003 is functionally equivalent to the black housing of other options.

Q: Which substitute should I choose for high-temperature applications?

A: The original 0393530003 is rated to 140°C. None of the active substitutes match this specification. ELXH03500 reaches 125°C, while 0395011003 and H-040-35003 are rated to 105°C maximum. For applications requiring 140°C operation, consult with the manufacturers regarding custom or specialized alternatives.

Q: Are all substitutes RoHS compliant?

A: Yes. All three substitutes carry RoHS compliance certifications (ROHS3 or RoHS), meeting current environmental and regulatory standards.

Q: What is the difference in contact tail length between parts?

A: Contact tail lengths vary slightly (0.134" to 0.140"), but all are within acceptable tolerances for through-hole solder mounting on standard PCB designs with 4.6mm pitch spacing.
