Molex 0520184416 Modular Connector Jack - Equivalent & Substitute Parts

Part Overview

The Molex 0520184416 is a modular connector jack designed for 4p4c (RJ9, RJ10, RJ22) applications with 90° right-angle orientation and unshielded configuration. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and new design implementations. The through-hole solder termination and board lock feature make this connector suitable for telecommunications and data communication applications requiring reliable modular connections.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0520184416 is determined by strict alignment of the following parameters:

• Connector type must be jack
• Contact configuration must be 4p4c (RJ9, RJ10, RJ22)
• Orientation must be 90° angle (right)
• Mounting type must be through hole
• Termination must be solder
• Shielding must be unshielded
• Tab direction must be up
• Contact material must be phosphor bronze with gold finish

The Amphenol ICC (FCI) part number 66010-004LF meets all these criteria and is designated as the manufacturer-recommended substitute. This part maintains functional and mechanical compatibility while offering improved availability status (Last Time Buy versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The Amphenol ICC (FCI) 66010-004LF is the qualified substitute for the obsolete Molex 0520184416. Selection is based on:

• Complete functional equivalence across all critical electrical and mechanical parameters
• Manufacturer-recommended status for direct replacement
• RoHS compliance maintained (RoHS Compliant versus ROHS3 Compliant)
• Improved product status (Last Time Buy provides extended availability compared to Obsolete)
• Identical ECCN and HTSUS classification for regulatory consistency
• Enhanced feature set (panel stops addition) provides improved mechanical stability without compromising compatibility

The substitute part is suitable for new designs and legacy system support where the original Molex component is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 66010-004LF be used as a direct replacement for the Molex 0520184416?

A: Yes. Both parts share identical connector type, contact configuration (4p4c RJ9/RJ10/RJ22), orientation (90° right angle), mounting method (through hole solder), and shielding characteristics (unshielded). The substitute maintains all functional and mechanical compatibility requirements.

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

A: The Molex part specifies 3.94µin (0.10µm) contact finish thickness, while the Amphenol ICC part specifies 5.00µin (0.127µm). Both thicknesses are within acceptable ranges for gold-plated phosphor bronze contacts in modular connector applications.

Q: Are there differences in operating temperature ranges?

A: Yes. The Molex 0520184416 operates from -40°C to 80°C, while the Amphenol ICC 66010-004LF operates from -55°C to 50°C. Application requirements must determine which temperature range is appropriate for the intended use case.

Q: What is the significance of the additional "Panel Stops" feature on the substitute part?

A: The Amphenol ICC part includes panel stops in addition to the board lock feature. This provides enhanced mechanical retention and alignment during connector mating, improving overall assembly robustness without affecting electrical performance or physical compatibility.

Q: How do the RoHS compliance statuses differ?

A: The Molex part is ROHS3 Compliant, while the Amphenol ICC part is RoHS Compliant. Both meet RoHS requirements; the designation difference reflects the specific RoHS directive version under which each part was certified.

Q: What is the packaging difference?

A: The Molex part packaging is not specified in the documentation. The Amphenol ICC substitute is supplied in bag packaging, which is standard for modular connector components.
