Substitute Part Grouping Explanation

The ARJ11C-MBSAU-A-B-3MU2 and its substitute ARJ11C-MBSAS-A-B-7MU2 share identical electrical and mechanical specifications across all critical parameters. Substitution is valid based on the following matching criteria:

• Connector Type: RJ45 (identical)
• Port Configuration: 1 port, 1 row (identical)
• Mounting and Orientation: Through hole, 90° right angle (identical)
• Termination Method: Solder (identical)
• Physical Dimensions: 0.535" height above board (identical)
• Electrical Performance: 10/100/1000 Base-T, AutoMDIX (identical)
• Shielding and EMI Protection: Shielded with EMI finger (identical)
• Contact Material and Finish: Gold plating (identical)
• Environmental Compliance: ROHS3, MSL 1, REACH unaffected (identical)

The only difference between these parts is packaging format (bulk versus tray), which does not affect functional compatibility or performance in end-use applications.

Parameter Comparison

Engineering Selection Recommendations

Both ARJ11C-MBSAU-A-B-3MU2 and ARJ11C-MBSAS-A-B-7MU2 are active production parts with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Packaging requirements: Choose bulk packaging (ARJ11C-MBSAU-A-B-3MU2) for direct component use or tray packaging (ARJ11C-MBSAS-A-B-7MU2) for automated assembly processes.
• Inventory availability: ARJ11C-MBSAS-A-B-7MU2 currently has higher stock levels (1303 pcs vs. 653 pcs).
• Supply chain logistics: Tray packaging may offer cost advantages for high-volume production runs.

Both parts maintain full ROHS3 compliance, unlimited moisture sensitivity rating, and identical environmental certifications (REACH unaffected, EAR99 classification).
