Parameter Comparison

Engineering Selection Recommendations

Both the ARJ11D-MASB-B-A-EMU2 and A63-113-213N491 are Active products with full ROHS3 compliance and REACH Unaffected status. Both connectors maintain identical operating temperature ranges (0°C ~ 70°C) and unlimited moisture sensitivity ratings (MSL 1), ensuring equivalent reliability in standard industrial and commercial environments.

The A63-113-213N491 features a thicker gold contact finish (15.0µin versus 6.00µin) and marginally reduced height above board (0.530" versus 0.545"), representing minor physical variations that do not affect functional compatibility in standard PCB layouts. Both parts are classified under identical HTSUS and ECCN codes, confirming regulatory equivalence.

Selection between these parts should be based on availability, lead time, packaging format (Tray for A63-113-213N491), and supply chain requirements rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can the A63-113-213N491 be used as a direct replacement for the ARJ11D-MASB-B-A-EMU2?

A: Yes. Both connectors meet identical specifications for RJ45 1-port 10/100 Base-T AutoMDIX applications with through-hole solder termination, 90° right-angle orientation, and board lock features. All critical electrical and mechanical parameters align.

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

A: The A63-113-213N491 provides a thicker gold plating (15.0µin versus 6.00µin), which may offer extended contact durability in high-cycle mating applications. Both finishes meet standard RJ45 specifications and do not affect functional compatibility.

Q: Are there PCB layout considerations due to the height difference?

A: The height difference is 0.015" (0.39mm), representing a minor variation. Standard PCB designs accommodating the ARJ11D-MASB-B-A-EMU2 will accept the A63-113-213N491 without layout modifications.

Q: Do both parts support AutoMDIX functionality?

A: Yes. Both the ARJ11D-MASB-B-A-EMU2 and A63-113-213N491 are specified for 10/100 Base-T AutoMDIX applications, enabling automatic MDI/MDIX detection and configuration.

Q: What packaging formats are available?

A: The ARJ11D-MASB-B-A-EMU2 packaging format is not specified in the provided data. The A63-113-213N491 is supplied in Tray packaging. Verify packaging requirements for your procurement process.

Q: Are both parts RoHS3 compliant?

A: Yes. Both connectors are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronics manufacturing.
