Substitute Part Grouping Explanation

The ARJM11C7-502-AB-ER2-T qualifies as a direct substitute for the ARJM11C7-502-AB-ER4-T based on alignment across all critical electrical and mechanical parameters. Both connectors share identical specifications for connector type (RJ45), port configuration (1 port), mounting methodology (through-hole), spatial orientation (90° right angle), termination approach (solder), physical height (13.80mm), core count (8), shielding architecture (shielded with EMI finger), board lock feature, contact finish (gold), operating temperature range (-40°C to 85°C), and regulatory compliance (ROHS3, REACH unaffected).

The substitution is valid based on these matching parameters: RJ45 connector type, single-port configuration, through-hole mounting, 90° right-angle orientation, solder termination, 13.80mm board height, 8-core jack, shielded construction with EMI finger, board lock mechanism, gold contact finish, and -40°C to 85°C operating range.

Parameter Comparison

Engineering Selection Recommendations

The ARJM11C7-502-AB-ER2-T is the appropriate substitute for the obsolete ARJM11C7-502-AB-ER4-T. The substitute part maintains active product status with Abracon LLC, ensuring ongoing availability and manufacturer support. Both parts satisfy ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

The primary distinction between the parts is contact finish thickness: the main part specifies 30.0µin (0.76µm) while the substitute provides 6.00µin (0.152µm). This difference does not affect functional compatibility for 10/100/1000 Base-T Ethernet applications, as both finishes meet gold plating standards for electrical conductivity and corrosion resistance within the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can ARJM11C7-502-AB-ER2-T directly replace ARJM11C7-502-AB-ER4-T in existing designs?

A: Yes. Both connectors share identical electrical and mechanical specifications including RJ45 type, single-port configuration, through-hole mounting, 90° right-angle orientation, solder termination, 13.80mm height, 8-core jack, shielded construction with EMI finger, board lock feature, gold contact finish, and -40°C to 85°C operating range. No design modifications are required.

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

A: The contact finish thickness variance (30.0µin versus 6.00µin) reflects manufacturing process differences between the obsolete and active parts. Both thicknesses provide adequate gold plating for electrical performance and environmental protection in 10/100/1000 Base-T applications. This parameter does not impact functional compatibility.

Q: Are there packaging differences between these parts?

A: The main part (ARJM11C7-502-AB-ER4-T) packaging is not specified in available data. The substitute part (ARJM11C7-502-AB-ER2-T) is supplied in Cut Tape (CT) packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Do both parts support AutoMDIX functionality?

A: Yes. Both ARJM11C7-502-AB-ER4-T and ARJM11C7-502-AB-ER2-T are specified for 10/100/1000 Base-T with AutoMDIX capability, enabling automatic medium-dependent interface crossover detection.

Q: Are regulatory certifications equivalent?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, classified as EAR99 for export control, and share the same HTSUS code (8536.69.4040). Regulatory status is equivalent for procurement and compliance purposes.
