Molex 0424104264 Modular Jack Connector 4P4C Equivalent & Substitute Parts

Part Overview

The Molex 0424104264 is a jack modular connector with 4 positions and 4 contacts (4P4C), commonly known as RJ9, RJ10, or RJ22 configuration. This connector features vertical orientation, through-hole mounting, and solder termination for Cat3 applications. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0424104264 is determined by strict equivalence across the following parameters:

• Connector type (Jack)
• Contact configuration (4P4C / RJ9, RJ10, RJ22)
• Mounting method (Through Hole)
• Orientation (Vertical)
• Termination type (Solder)
• Shielding classification (Unshielded)
• Operating temperature range (-40°C to 85°C minimum)
• Physical features (Board Lock, Panel Stops)
• Contact material (Phosphor Bronze)
• Contact finish (Gold)

All identified substitute parts meet these core electrical and mechanical requirements. Variations in contact finish thickness, housing material composition, and product status are noted but do not preclude functional substitution within the specified parameters.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0424104264 is obsolete and requires substitution for new procurement. The following parts are functionally equivalent based on provided specifications:

Primary Recommendation: Molex 0424104168 This part is from the same manufacturer and series (42410) as the original component. It maintains identical electrical and mechanical specifications, including contact finish thickness of 50.0µin (1.27µm). Product status is active with 1110 units in stock. RoHS3 compliance is maintained.

Secondary Recommendation: TE Connectivity 5520257-2 This part meets all core substitution parameters and is manufacturer-recommended. Housing material includes both PBT and Polyester composition. Product status is active with 2300 units in stock. RoHS compliance is confirmed.

Alternative Options: Assmann WSW A-2014-3-1, A-2014-3-2, A-2014-3-3 All three Assmann variants meet functional requirements. A-2014-3-3 matches the original contact finish thickness of 50.0µin (1.27µm). A-2014-3-2 provides 30.0µin thickness, and A-2014-3-1 provides 15.0µin thickness. All are active products with ROHS3 compliance and REACH unaffected status.

Selection should prioritize active product status and compliance certifications relevant to the application. Contact finish thickness variations are within acceptable ranges for Cat3 modular connector applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0424104168 directly replace the obsolete 0424104264? A: Yes. Both parts share identical specifications for connector type, contact configuration, mounting method, orientation, termination, shielding, operating temperature, and physical features. The primary difference is product status (active vs. obsolete) and packaging (tray vs. unspecified).

Q: What is the significance of contact finish thickness variation among substitute parts? A: Contact finish thickness affects durability and wear resistance. The original part and Molex 0424104168 specify 50.0µin (1.27µm), matching Assmann A-2014-3-3. Assmann A-2014-3-2 (30.0µin) and A-2014-3-1 (15.0µin) provide reduced thickness. All thicknesses are within acceptable parameters for Cat3 applications but may differ in contact life expectancy under repeated mating cycles.

Q: Are all substitute parts RoHS compliant? A: Yes. Molex 0424104264, 0424104168, and all Assmann variants are ROHS3 compliant. TE Connectivity 5520257-2 is RoHS compliant. All parts meet regulatory requirements for restricted substance content.

Q: What is the difference between Molex 0424104264 and 0424104168 beyond product status? A: The primary difference is packaging. Molex 0424104264 packaging is unspecified, while 0424104168 is packaged in trays. Electrical and mechanical specifications are identical, including the 42410 series designation.

Q: Can TE Connectivity 5520257-2 be used in applications originally designed for Molex parts? A: Yes. TE Connectivity 5520257-2 meets all specified electrical and mechanical parameters. Housing material composition differs slightly (PBT and Polyester vs. Polyester alone), but this does not affect functional compatibility within the defined operating parameters.

Q: Which substitute part offers the best availability? A: TE Connectivity 5520257-2 has the highest inventory level at 2300 units in stock, followed by Molex 0424104168 at 1110 units. Assmann variants range from 813 to 1122 units in stock.
