Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ARJ11C-MASAA-B-A-1LU2 is determined by the following critical 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
• Contact Finish: Gold
• Operating Temperature Range: 0°C ~ 70°C
• RoHS Compliance: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

The substitute part A63-113-213N491 meets all mechanical and electrical compatibility criteria. Application differences (10/100 Base-T vs. 10/100/1000 Base-T) and core count variations (4 vs. 5 cores) are noted but do not preclude substitution in systems designed for the lower bandwidth specification.

Parameter Comparison

Engineering Selection Recommendations

Both the ARJ11C-MASAA-B-A-1LU2 and A63-113-213N491 maintain active product status and full ROHS3 compliance. The substitute part carries equivalent regulatory certifications (REACH Unaffected, EAR99 classification) and identical MSL ratings.

Selection between these parts should be based on application bandwidth requirements. The ARJ11C-MASAA-B-A-1LU2 supports 10/100/1000 Base-T operation, while the A63-113-213N491 is rated for 10/100 Base-T with AutoMDIX capability. The A63-113-213N491 features increased contact finish thickness (15.0µin vs. 6.00µin), which may provide enhanced durability in high-cycle mating environments.

Frequently Asked Questions (FAQ)

Q: Can A63-113-213N491 replace ARJ11C-MASAA-B-A-1LU2 in all applications?

A: Substitution is mechanically and electrically compatible for applications operating at 10/100 Base-T speeds. Systems requiring 1000 Base-T operation must use the ARJ11C-MASAA-B-A-1LU2 or equivalent gigabit-rated connectors.

Q: What is the significance of the core count difference (5 vs. 4)?

A: The ARJ11C-MASAA-B-A-1LU2 includes 5 cores per jack, while the A63-113-213N491 includes 4 cores. This difference reflects the bandwidth specifications of each connector. The 4-core configuration is standard for 10/100 Base-T applications.

Q: Are the height differences significant for PCB layout?

A: The height difference is 0.005" (0.14mm), which is negligible for most PCB designs. Both connectors maintain compatible through-hole footprints and board lock mechanisms.

Q: Do both parts have identical packaging?

A: Both parts are supplied in tray packaging. Inventory availability differs: ARJ11C-MASAA-B-A-1LU2 has 648 units in stock, while A63-113-213N491 has 1361 units in stock.

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99. No compliance barriers exist for substitution.
