Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ARJ11B-MASAF-MU2 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Electrical Compatibility Criteria:

• Connector Type: RJ45
• Number of Ports: 1
• Applications: 10/100 Base-T, AutoMDIX
• Number of Cores per Jack: 4
• Shielding: Shielded, EMI Finger

Mechanical Compatibility Criteria:

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

Environmental & Compliance Criteria:

• Operating Temperature: 0°C ~ 70°C
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)
• REACH Status: REACH Unaffected

The identified substitutes maintain equivalence across all critical parameters while allowing variation in packaging format, manufacturer, and non-critical specifications such as height above board (within tolerance) and contact finish thickness.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and full compliance with ROHS3 and REACH requirements. Selection between ARJ11B-MASAF-MU2, ARJ11B-MASAA-MU2, and A63-113-300P422 is determined by packaging and inventory requirements rather than electrical or mechanical performance differences.

ARJ11B-MASAF-MU2 and ARJ11B-MASAA-MU2 are functionally identical Abracon LLC parts differing only in packaging format. Both maintain identical height above board (0.545"), contact finish thickness (6.00µin), and all electrical specifications. The primary distinction is packaging: ARJ11B-MASAF-MU2 uses standard packaging while ARJ11B-MASAA-MU2 uses tray packaging.

A63-113-300P422 from Mercury United Electronics, Inc. provides an alternative from a different manufacturer. This part maintains all critical electrical and mechanical parameters with a minor height variance (0.531" versus 0.545") and increased contact finish thickness (15.0µin versus 6.00µin). Both height and finish thickness variations remain within acceptable tolerance ranges for 10/100 Base-T RJ45 applications.

Frequently Asked Questions (FAQ)

Q: Can ARJ11B-MASAA-MU2 be used as a direct replacement for ARJ11B-MASAF-MU2?

A: Yes. Both parts are manufactured by Abracon LLC with identical electrical and mechanical specifications. The only difference is packaging format (tray versus standard). Direct PCB footprint and electrical compatibility are maintained.

Q: Is A63-113-300P422 compatible with designs specified for ARJ11B-MASAF-MU2?

A: Yes. A63-113-300P422 maintains all critical RJ45 connector specifications including connector type, port configuration, 10/100 Base-T AutoMDIX capability, through-hole mounting, 90° right angle orientation, solder termination, shielding with EMI finger, and board lock feature. The height above board difference (0.531" versus 0.545") and contact finish thickness increase (15.0µin versus 6.00µin) are within acceptable tolerances for this connector category.

Q: What are the key parameters that determine substitutability for this RJ45 connector?

A: Substitutability is determined by: connector type (RJ45), port count (1), application support (10/100 Base-T AutoMDIX), mounting method (through hole), orientation (90° right angle), termination type (solder), shielding configuration (shielded with EMI finger), board lock presence, operating temperature range (0°C ~ 70°C), and compliance certifications (ROHS3, REACH).

Q: Does packaging format affect electrical performance?

A: No. Packaging format (standard versus tray) affects only handling, storage, and supply chain logistics. Electrical and mechanical performance remain identical between ARJ11B-MASAF-MU2 and ARJ11B-MASAA-MU2.

Q: Are all three parts suitable for 10/100 Base-T Ethernet applications?

A: Yes. All three parts are specified for 10/100 Base-T applications with AutoMDIX capability and maintain identical core jack configuration (4 cores) and shielding specifications required for this application category.
