Key Parameters

Substitute Part Grouping Explanation

The ARJ11E-MASC-L2 accepts A60-113-300P492 as a manufacturer-recommended substitute based on the following alignment criteria:

Matching Parameters:

• Connector Type: RJ45
• Number of Ports: 1
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination: Solder
• Shielding: Shielded, EMI Finger
• Features: Board Lock
• Tab Direction: Down
• Operating Temperature: 0°C ~ 70°C
• Contact Finish: Gold
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)
• ECCN: EAR99
• HTSUS: 8536.69.4040

Application Compatibility: Both connectors support 10/100/1000 Ethernet standards with AutoMDIX functionality. The ARJ11E-MASC-L2 specifies 10/100/1000 Base-TX, while the A60-113-300P492 specifies 10/100/1000 Base-T. Both designations indicate compatibility with gigabit Ethernet applications.

Parameter Comparison

Engineering Selection Recommendations

Both the ARJ11E-MASC-L2 and A60-113-300P492 meet ROHS3 compliance and carry unlimited moisture sensitivity ratings, making them suitable for standard PCB assembly environments. Both parts maintain identical operating temperature ranges and are classified under the same ECCN and HTSUS codes, confirming regulatory equivalence.

The A60-113-300P492 features a thicker gold contact finish (15.0µin versus 6.00µin), which may provide enhanced durability in high-cycle mating applications. The substitute part uses 8 cores per jack compared to the original 12 cores; however, both configurations support the same 10/100/1000 Ethernet standards with AutoMDIX operation.

Physical height above board differs by 0.010" (0.25mm), which is negligible for most PCB layout considerations. Both parts are actively produced with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can A60-113-300P492 be used as a direct replacement for ARJ11E-MASC-L2?

A: Yes. Both connectors share identical connector type, port configuration, mounting method, orientation, termination, shielding, and operating specifications. The parts are electrically and mechanically compatible for 10/100/1000 Ethernet applications.

Q: What is the significance of the difference in core count (12 versus 8)?

A: The ARJ11E-MASC-L2 specifies 12 cores per jack, while the A60-113-300P492 specifies 8 cores. Both configurations support standard RJ45 Ethernet pinouts and 10/100/1000 Base-T/Base-TX operation. The core count difference does not affect functional compatibility in standard network applications.

Q: How do the contact finish thicknesses compare?

A: The A60-113-300P492 provides 15.0µin (0.38µm) gold plating versus 6.00µin (0.152µm) on the ARJ11E-MASC-L2. The thicker finish on the substitute part may offer extended contact life in applications requiring frequent mating cycles.

Q: Are there packaging differences between these parts?

A: The ARJ11E-MASC-L2 packaging is not specified in the provided data. The A60-113-300P492 is supplied in Tray packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Do both parts support AutoMDIX functionality?

A: Yes. Both the ARJ11E-MASC-L2 and A60-113-300P492 are specified for AutoMDIX operation, enabling automatic detection and configuration of straight-through or crossover cable connections.

Q: Are there any compliance or regulatory differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified under identical ECCN (EAR99) and HTSUS (8536.69.4040) codes. Both carry MSL rating 1 (unlimited moisture sensitivity).
