Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ARJM11C7-809-AB-CW4 is determined by strict equivalence across the following critical parameters:

• Connector Type: RJ45
• Number of Ports: 1
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination: Solder
• Height Above Board: 0.543" (13.80mm)
• Number of Cores per Jack: 8
• Shielding: Shielded, EMI Finger
• Features: Board Lock
• Contact Finish: Gold
• Operating Temperature Range: 0°C ~ 70°C
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The ARJM11C7-809-AB-CW2 meets all substitution criteria as a direct equivalent within the ARJM11 series, with identical electrical and mechanical specifications. The primary distinction is product status (Active vs. Obsolete) and contact finish thickness variance, which does not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The ARJM11C7-809-AB-CW2 is the direct substitute for the obsolete ARJM11C7-809-AB-CW4. Both parts maintain identical electrical and mechanical specifications, ensuring pin-for-pin and form-factor compatibility. The substitute part carries Active product status, providing assured long-term availability and supply chain continuity.

Both parts satisfy ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for current manufacturing standards. The contact finish thickness difference (30.0µin vs. 6.00µin) does not impact functional performance or reliability within the specified operating temperature range of 0°C to 70°C.

Selection of the ARJM11C7-809-AB-CW2 eliminates obsolescence risk while maintaining full design compatibility with existing PCB layouts and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the ARJM11C7-809-AB-CW2 be used as a direct replacement for the ARJM11C7-809-AB-CW4 without PCB redesign?

A: Yes. Both connectors are mechanically and electrically identical. The ARJM11C7-809-AB-CW2 maintains the same 90° right-angle orientation, 0.543" (13.80mm) height above board, solder termination, and 8-core RJ45 configuration. No PCB layout modifications are required.

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

A: The contact finish thickness variance (30.0µin vs. 6.00µin) reflects manufacturing process differences within the same gold plating specification. Both thicknesses provide equivalent electrical conductivity and corrosion resistance within the 0°C to 70°C operating temperature range. This difference does not affect connector performance or reliability.

Q: Why is the ARJM11C7-809-AB-CW4 classified as Obsolete?

A: Obsolescence status indicates the part is no longer in active production. The ARJM11C7-809-AB-CW2 serves as the current production equivalent within the ARJM11 series, ensuring continued availability for new designs and field service applications.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the ARJM11C7-809-AB-CW4 and ARJM11C7-809-AB-CW2 are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations.

Q: What is the Moisture Sensitivity Level (MSL) rating, and does it affect handling?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special desiccant or humidity control requirements.
