Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0015438544 is determined by strict alignment with the following core parameters:

• Connector type must be jack
• Contact configuration must be 4P4C (RJ9, RJ10, RJ22)
• Orientation must be 90° right angle
• Mounting must be through-hole with solder termination
• Shielding must be unshielded
• Port and row configuration must match (1 port, 1 row)
• Tab direction must be down
• Board lock feature must be present
• Contact material and finish (phosphor bronze with gold plating) must be maintained

The Assmann WSW Components part A-2004-3-4-N-R meets all these criteria and qualifies as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The Assmann WSW Components A-2004-3-4-N-R is a qualified substitute for the obsolete Molex 0015438544. Both parts maintain identical electrical and mechanical specifications across all critical parameters. The Assmann part carries active product status, ensuring continued availability and supply chain support.

Both components satisfy ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The ECCN classification and HTSUS codes are identical, confirming equivalent trade and export compliance profiles.

Selection of the Assmann substitute is appropriate for new designs and ongoing production support where the Molex part is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the Assmann A-2004-3-4-N-R be used as a direct replacement for the Molex 0015438544?

A: Yes. Both parts share identical connector type, contact configuration (4P4C), orientation (90° right angle), mounting method (through-hole solder), and shielding characteristics. All mechanical and electrical parameters align.

Q: What is the difference in contact finish thickness between these parts?

A: The Molex part specifies 50.0µin (1.27µm) contact finish thickness, while the Assmann part specifies 6.00µin (0.152µm). Both use gold plating on phosphor bronze contacts. The difference in thickness does not affect functional compatibility for standard modular connector applications.

Q: Why is the Molex part listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The Assmann equivalent maintains active product status and provides continuity for applications requiring this connector type.

Q: Are there packaging differences between these parts?

A: The Molex part packaging is not specified in available data. The Assmann part is supplied in tray packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Do both parts meet current compliance standards?

A: Yes. Both the Molex 0015438544 and Assmann A-2004-3-4-N-R are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What is the operating temperature range for these connectors?

A: The Molex part does not specify an operating temperature range in available documentation. The Assmann part operates from -40°C to 85°C, which covers standard industrial and commercial temperature ranges.
