Substitute Part Grouping Explanation

Substitution eligibility for the ARJM11B1-502-AB-CW4 is determined by strict equivalence across the following critical parameters:

• Connector Type: RJ45
• Number of Ports: 1
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination: Solder
• Applications: 10/100/1000 Base-T, AutoMDIX
• Height Above Board: 0.535" (14.69mm)
• Number of Cores per Jack: 8
• Shielding: Shielded
• Features: Board Lock
• Contact Finish: Gold
• Operating Temperature Range: 0°C ~ 70°C
• RoHS Compliance: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Variations in contact finish thickness and product status do not affect functional compatibility when all electrical and mechanical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

The ARJM11B1-502-AB-CW2 is a direct functional equivalent to the ARJM11B1-502-AB-CW4. Both parts maintain identical electrical and mechanical specifications across all critical parameters including connector type, port configuration, mounting method, orientation, termination, and operating temperature range.

The primary distinction is product status: the ARJM11B1-502-AB-CW4 is Obsolete, while the ARJM11B1-502-AB-CW2 is Active. Both parts are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements. The contact finish thickness difference (30.0µin versus 6.00µin) does not affect functional compatibility for 10/100/1000 Base-T Ethernet applications.

For new designs and production continuity, the ARJM11B1-502-AB-CW2 is the appropriate selection due to its Active status and continued availability.

Frequently Asked Questions (FAQ)

Q: Can the ARJM11B1-502-AB-CW2 be used as a direct replacement for the ARJM11B1-502-AB-CW4?

A: Yes. Both parts are electrically and mechanically equivalent across all functional parameters. The ARJM11B1-502-AB-CW2 is the Active production equivalent of the Obsolete ARJM11B1-502-AB-CW4.

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

A: Contact finish thickness (30.0µin versus 6.00µin) does not affect electrical performance or compatibility in 10/100/1000 Base-T Ethernet applications. Both thicknesses provide adequate gold plating for reliable solder connections and signal integrity.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the ARJM11B1-502-AB-CW4 and ARJM11B1-502-AB-CW2 are ROHS3 Compliant and REACH Unaffected, meeting current regulatory standards.

Q: What does the Obsolete status mean for the ARJM11B1-502-AB-CW4?

A: Obsolete status indicates the part is no longer in active production. The ARJM11B1-502-AB-CW2 is the recommended Active alternative for new designs and ongoing production requirements.

Q: Are the PCB footprints identical between these two parts?

A: Yes. Both parts share identical mounting specifications, including Through Hole configuration, 90° right-angle orientation, and 0.535" (14.69mm) height above board, ensuring PCB footprint compatibility.
