Engineering Selection Recommendations

ARJ11E-MBSA-A-B-EM2 (Abracon LLC) is the primary substitute for ARJ11E-MCSB-A-B-EM2. Both parts are manufactured by Abracon LLC, share identical electrical specifications for 10/100/1000 Base-TX applications, and maintain equivalent mechanical dimensions and compliance certifications. The primary distinction is packaging format (tray vs. original packaging). Both parts are ROHS3 compliant and carry active product status.

A60-113-331P432 (Mercury United Electronics, Inc.) is a secondary substitute option. While this part maintains mechanical and thermal compatibility, it is specified for 10/100/1000 Base-T applications rather than Base-TX. The height above board differs by 0.010" (0.25mm). This part remains ROHS3 compliant and active in production. Selection of this substitute requires confirmation that Base-T operation is acceptable for the target application.

All three parts maintain identical core electrical parameters: 8-core RJ45 configuration, shielded design with EMI finger, solder termination, and AutoMDIX support.

Frequently Asked Questions (FAQ)

Q: Can ARJ11E-MBSA-A-B-EM2 be used as a direct replacement for ARJ11E-MCSB-A-B-EM2?

A: Yes. Both parts are manufactured by Abracon LLC and share identical electrical specifications, mechanical dimensions, and compliance certifications. The difference is packaging format only.

Q: What is the difference between Base-TX and Base-T applications?

A: Base-TX and Base-T are both Ethernet standards supporting 10/100/1000 Mbps speeds with AutoMDIX. The primary difference lies in transmission characteristics and cable specifications. ARJ11E-MCSB-A-B-EM2 and ARJ11E-MBSA-A-B-EM2 are specified for Base-TX, while A60-113-331P432 is specified for Base-T. Substitution between these standards requires application-level verification.

Q: Are there height differences between substitute parts?

A: ARJ11E-MCSB-A-B-EM2 and ARJ11E-MBSA-A-B-EM2 both measure 0.545" (13.84mm) above board. A60-113-331P432 measures 0.535" (14.69mm), a difference of 0.010" (0.25mm). This minor variance may be relevant for applications with strict PCB clearance constraints.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification. Moisture sensitivity level is 1 (Unlimited) for all parts.

Q: What packaging formats are available?

A: ARJ11E-MCSB-A-B-EM2 packaging is not specified in the data. ARJ11E-MBSA-A-B-EM2 and A60-113-331P432 are supplied in tray packaging.
