Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 90520-003LF is determined by strict alignment with the following critical parameters:

• Connector type: Jack
• Contact configuration: 6p6c (RJ11, RJ12, RJ14, RJ25)
• Mounting method: Through hole
• Orientation: Vertical
• Termination method: Solder
• Shielding configuration: Unshielded
• Category rating: Cat3
• Tab direction: User selectable
• Contact finish: Gold plated
• Moisture sensitivity level: 1 (Unlimited)

Both identified substitute parts meet these core electrical and mechanical requirements. Variations in housing material, contact base material, contact finish thickness, and operating temperature upper limit do not affect functional compatibility within the specified application parameters.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are functionally equivalent to the 90520-003LF within the specified application parameters.

69254-001LF (Amphenol ICC): This part maintains identical electrical and mechanical specifications to the main part, including contact finish thickness and operating temperature range. The housing material differs (glass-filled nylon versus polyester), but this variation does not affect connector function. The part is active in production with RoHS3 compliance and REACH unaffected status. This option provides direct compatibility with minimal design consideration.

0424106168 (Molex): This part meets all core substitution criteria with equivalent electrical performance. The contact finish thickness is thicker (50.0µin versus 5.00µin), providing enhanced durability in high-cycle applications. The operating temperature upper limit extends to 80°C, offering broader thermal margin. The part is active in production with RoHS3 compliance and REACH unaffected status. This option is suitable for applications requiring extended thermal performance.

Selection between the two substitutes depends on application-specific requirements regarding thermal operating range and contact durability expectations. Both parts are currently in active production with full compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can the 69254-001LF directly replace the 90520-003LF without PCB modification?

A: Yes. Both parts share identical mounting type (through hole), orientation (vertical), contact configuration (6p6c), and termination method (solder). No PCB layout changes are required.
