Parameter Comparison

Engineering Selection Recommendations

Both the ARJ11C-MASAB-B-A-2MU2 and A63-113-213N491 are active production parts with full ROHS3 compliance and REACH unaffected status. The substitute part A63-113-213N491 offers higher contact finish thickness (15.0µin versus 6.00µin), which may provide enhanced durability in high-cycle mating applications. Both parts maintain identical electrical specifications for 10/100 Base-T networking and are functionally interchangeable at the board level. The height differential of 0.05" (0.14mm) is negligible for most PCB layout considerations. Selection between these parts should be based on availability, lead time, and packaging requirements rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can A63-113-213N491 be used as a direct replacement for ARJ11C-MASAB-B-A-2MU2?

A: Yes. Both connectors share identical functional specifications for RJ45 1-port through-hole 10/100 Base-T applications with AutoMDIX, board lock, and EMI shielding. The mechanical dimensions are within 0.05" vertically, which does not impact standard PCB designs.

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

A: The A63-113-213N491 features 15.0µin contact finish thickness compared to 6.00µin on the ARJ11C-MASAB-B-A-2MU2. This thicker gold plating on the Mercury United part may extend connector life in applications with frequent mating cycles, though both meet standard reliability requirements for typical networking installations.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications. They meet the same regulatory requirements for commercial networking equipment.

Q: Does packaging affect the substitution decision?

A: The A63-113-213N491 is supplied in tray packaging, while the ARJ11C-MASAB-B-A-2MU2 packaging is not specified. Packaging choice may influence handling, storage, and assembly line integration but does not affect electrical or mechanical compatibility.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both connectors operate within 0°C to 70°C, making them suitable for identical thermal environments in standard commercial networking applications.
