Molex 0009523033 Equivalent & Substitute Parts

Part Overview

The Molex 0009523033 is a 3-position receptacle connector with 0.156" (3.96mm) pitch, designed for through-hole PCB mounting with solder termination. This connector is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The part is suitable for automotive, general purpose, medical, and telecommunications applications requiring board-to-board or cable connections.

Substitute Part Grouping Explanation

Substitution for the Molex 0009523033 is determined by strict alignment of the following critical parameters:

Connector Type & Position Count: All substitutes must be 3-position receptacles
Pitch Specification: Mating pitch must remain 0.156" (3.96mm) for mechanical compatibility
Mounting & Termination: Through-hole solder termination is required
Electrical Ratings: Voltage (600V) and current capacity must meet or exceed the original specification
Contact Finish: Tin plating on mating surfaces ensures compatibility with existing mating connectors
Compliance: RoHS3 compliance is mandatory for current production

The two substitute parts listed below meet these core substitution criteria while offering improvements in product status and material specifications.

Engineering Selection Recommendations

For Active Production Programs: The Molex 0009482033 is the manufacturer-recommended substitute. It maintains identical electrical ratings (4.5A, 600V) and operating temperature range (-40°C ~ 80°C) as the original part while offering improved material specifications (UL94 V-0 flammability rating, polyester insulation). Active product status ensures long-term availability and supply chain stability.

For Extended Temperature Applications: The Molex 0009484038 provides an extended operating temperature range (-40°C ~ 105°C) and increased current capacity (5A), with superior flammability rating (UL94 V-0). This option is suitable for applications requiring higher thermal performance. Contact material differs (phosphor bronze vs. brass), which may affect contact resistance characteristics in specific applications.

Compliance Assurance: Both substitute parts maintain ROHS3 compliance and are actively manufactured, eliminating obsolescence risk associated with the original part number.

Frequently Asked Questions (FAQ)

Q: Can the 0009484038 be used in place of the 0009523033 in existing designs?

A: Yes. Both parts share identical connector type, position count, pitch (0.156"), mounting method (through-hole), and termination (solder). The 0009484038 offers improved specifications: higher current rating (5A vs. 4.5A), extended temperature range (-40°C ~ 105°C vs. -40°C ~ 80°C), and superior flammability rating (UL94 V-0 vs. V-2). These are compatible upgrades for the same mating interface.

Q: What is the difference between the two substitute parts?

A: The 0009482033 maintains the original electrical specifications (4.5A, -40°C ~ 80°C) while upgrading material quality and flammability rating. The 0009484038 increases current capacity to 5A and extends the temperature range to 105°C, with different contact material (phosphor bronze). Both are active products with superior compliance profiles compared to the obsolete original.

Q: Are there packaging differences between these parts?

A: The original 0009523033 is supplied in standard packaging. Both substitutes are supplied in trays, which is standard for active production inventory. Tray packaging is compatible with automated assembly processes.

Q: Will these substitutes work with existing mating connectors designed for the 0009523033?

A: Yes. All three parts maintain the same 0.156" (3.96mm) pitch, receptacle configuration, and tin-plated mating contacts. Mechanical and electrical compatibility with existing mating connectors is assured.

Q: Which substitute should be selected for new designs?

A: The 0009482033 is the manufacturer-recommended choice for direct replacement. For applications requiring higher current capacity or extended temperature operation, the 0009484038 is appropriate. Both are active products with full RoHS3 compliance.
