Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 54601-704WPLF is determined by strict alignment of the following critical parameters:

• Connector Type: Jack (fixed requirement)
• Contact Configuration: 4p4c (RJ9, RJ10, RJ22) (fixed requirement)
• Orientation: 90° Angle (Right) (fixed requirement)
• Shielding: Unshielded (fixed requirement)
• Mounting Type: Through Hole (fixed requirement)
• Termination Method: Solder (fixed requirement)
• Number of Ports: 1 (fixed requirement)
• Number of Rows: 1 (fixed requirement)
• Operating Temperature Range: -40°C ~ 70°C (fixed requirement)
• RoHS Compliance: Required (fixed requirement)

The substitute part 87180-044LF meets all critical electrical and mechanical parameters required for direct substitution. Variations in contact material composition, contact finish thickness specification, and product status do not affect functional compatibility within the defined operating parameters.

Parameter Comparison

Engineering Selection Recommendations

The 87180-044LF is a direct functional equivalent to the 54601-704WPLF for all electrical and mechanical applications. The substitute part is manufactured by the same supplier (Amphenol ICC/FCI) and maintains Active product status, ensuring long-term availability and supply chain stability compared to the Last Time Buy status of the original part.

Both components satisfy RoHS compliance requirements and operate within identical temperature ranges (-40°C ~ 70°C). The substitute part carries REACH Affected designation, which may require evaluation based on specific end-use application requirements and regional regulatory obligations.

Packaging format differs between the two parts (Bulk versus Tube); procurement and inventory management processes should account for this distinction when transitioning designs to the substitute component.

Frequently Asked Questions (FAQ)

Q: Can 87180-044LF be used as a direct replacement for 54601-704WPLF in existing designs?

A: Yes. Both parts share identical connector type, contact configuration (4p4c RJ9/RJ10/RJ22), orientation (90° right-angle), shielding (unshielded), mounting method (through hole), and termination (solder). Operating temperature ranges and RoHS compliance are equivalent.

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

A: The 54601-704WPLF uses Copper Alloy contacts with flash gold finish. The 87180-044LF uses Phosphor Bronze contacts with gold finish at 5.00µin (0.127µm) thickness. Both materials and finishes are suitable for 4p4c modular connector applications within the specified operating parameters.

Q: Why is the original part marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued production of the 54601-704WPLF. The 87180-044LF remains in Active production status, making it the recommended path for new designs and ongoing supply requirements.

Q: Does packaging format affect electrical or mechanical compatibility?

A: No. The difference between Bulk and Tube packaging is a logistics and handling consideration only. It does not affect the electrical performance, mechanical fit, or functional compatibility of the connector in circuit applications.

Q: Are there any regulatory compliance differences between these parts?

A: Both parts are RoHS Compliant. The 87180-044LF carries additional REACH Affected designation. Applications subject to REACH regulations should evaluate this status against specific end-use requirements and regional compliance obligations.

Q: What is the Cat3 rating on the 87180-044LF?

A: Cat3 (Category 3) is a telecommunications cable rating classification. This designation on the 87180-044LF indicates suitability for voice and data transmission applications. It does not affect compatibility with the 54601-704WPLF for standard 4p4c modular connector applications.
