Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ARJ11E-MASA-M2 is determined by strict alignment of the following critical parameters:

Electrical Compatibility Parameters:

• Connector Type: RJ45
• Number of Ports: 1
• Number of Cores per Jack: 8
• Shielding Configuration: Shielded with EMI Finger
• Operating Temperature Range: 0°C ~ 70°C
• Applications: 10/100/1000 Base-T/Base-TX with AutoMDIX

Mechanical Compatibility Parameters:

• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination Method: Solder
• Features: Board Lock
• Tab Direction: Down

Regulatory & Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The substitute part A60-113-300P492 meets all critical electrical and mechanical parameters. Minor variations in physical dimensions (Height Above Board: 0.535" vs 0.545"), contact finish thickness (15.0µin vs 6.00µin), and material specifications (Phosphor Bronze contact material, Copper Alloy shield, PBT housing) do not preclude substitution when the connector footprint and board layout accommodate the specified height tolerance.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: ARJ11E-MASA-M2

The ARJ11E-MASA-M2 maintains Active product status with established inventory availability (887 pieces). This part is ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 for export purposes. The connector is suitable for immediate deployment in 10/100/1000 Base-TX applications requiring AutoMDIX functionality.

Substitute Part: A60-113-300P492

The A60-113-300P492 from Mercury United Electronics is an equivalent substitute meeting all critical electrical and mechanical specifications. This part is also ROHS3 compliant, REACH unaffected, and carries the same ECCN and HTSUS classifications. Inventory availability is higher at 1021 pieces.

Selection Criteria:

Both parts satisfy identical regulatory compliance requirements and functional specifications for 10/100/1000 Base-T/Base-TX Ethernet applications. The 0.25mm height variation (0.535" vs 0.545") is within typical PCB layout tolerances and does not affect electrical performance or mechanical fit in standard through-hole applications. Selection between these parts should be based on supply chain availability, lead time requirements, and established vendor relationships.

Frequently Asked Questions (FAQ)

Q: Can the A60-113-300P492 be used as a direct replacement for the ARJ11E-MASA-M2 in existing designs?

A: Yes. Both connectors share identical electrical specifications (RJ45, 8-core, shielded with EMI finger, 10/100/1000 Base-T/Base-TX AutoMDIX), mechanical mounting (Through Hole, 90° right angle, solder termination, board lock), and regulatory compliance (ROHS3, REACH unaffected). The 0.25mm height difference falls within standard PCB design tolerances.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching: Connector Type (RJ45), Number of Ports (1), Mounting Type (Through Hole), Orientation (90° Right), Termination (Solder), Core Count (8), Shielding (Shielded EMI Finger), Operating Temperature (0°C ~ 70°C), and Regulatory Status (ROHS3 Compliant, REACH Unaffected).

Q: Are there any material differences between these connectors?

A: The A60-113-300P492 specifies Phosphor Bronze contact material, Copper Alloy shield material, and PBT (Glass Filled) housing. The ARJ11E-MASA-M2 does not provide these material specifications in the available documentation. Both connectors use gold contact finish and meet identical performance standards.

Q: What is the significance of the contact finish thickness difference?

A: The A60-113-300P492 has 15.0µin (0.38µm) contact finish thickness compared to 6.00µin (0.152µm) for the ARJ11E-MASA-M2. Both exceed minimum gold plating requirements for RJ45 connectors and provide equivalent electrical contact performance and corrosion resistance in standard operating environments.

Q: Are both parts suitable for high-speed Ethernet applications?

A: Yes. Both connectors support 10/100/1000 Base-T/Base-TX applications with AutoMDIX capability, meeting the electrical requirements for Gigabit Ethernet transmission over twisted-pair cabling.

Q: What is the packaging format for these connectors?

A: Both parts are supplied in Tray packaging. The ARJ11E-MASA-M2 has 887 pieces in current inventory, while the A60-113-300P492 has 1021 pieces available.
