Substitute Part Grouping Explanation

Substitution eligibility for the ARJM11D7-007-KB-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)
• Shielding: Shielded
• Features: Board Lock
• Tab Direction: Up
• Contact Finish: Gold
• Operating Temperature Range: 0°C ~ 70°C
• RoHS and REACH Compliance Status

The ARJM11D7-009-KB-CW2 meets all substitution criteria as an Active product within the same ARJM11 series, maintaining identical mechanical, electrical, and environmental specifications. The variance in Contact Finish Thickness (30.0µin vs. 6.00µin) does not affect functional compatibility for 10/100 Base-T applications.

Parameter Comparison

Engineering Selection Recommendations

The ARJM11D7-009-KB-CW2 is the qualified substitute for the obsolete ARJM11D7-007-KB-CW4. Selection is based on:

• Active product status ensuring continued availability and manufacturing support
• Full compliance with ROHS3 and REACH regulatory requirements
• Identical mechanical footprint and electrical specifications for direct PCB compatibility
• Equivalent environmental operating range and moisture sensitivity classification
• Same connector series (ARJM11) and functional performance for 10/100 Base-T AutoMDIX applications

Frequently Asked Questions (FAQ)

Q: Can ARJM11D7-009-KB-CW2 be used as a direct replacement for ARJM11D7-007-KB-CW4?

A: Yes. Both connectors share identical mechanical dimensions, electrical specifications, mounting configuration, and environmental ratings. The parts are pin-compatible and functionally equivalent for 10/100 Base-T applications.

Q: What is the difference in Contact Finish Thickness between these parts?

A: The main part specifies 30.0µin (0.76µm) while the substitute specifies 6.00µin (0.152µm). Both thicknesses meet gold plating standards for RJ45 connectors and do not affect electrical performance or compatibility in this application category.

Q: Why is the original part marked as Obsolete?

A: Product status reflects manufacturer lifecycle decisions. The ARJM11D7-009-KB-CW2 remains Active, providing continued design support and procurement availability for equivalent functionality.

Q: Are there any PCB layout or assembly considerations when switching to the substitute part?

A: No. Identical height above board (0.543" / 13.80mm), orientation (90° right angle), and through-hole mounting specifications ensure no PCB redesign is required.

Q: Do both parts meet the same compliance standards?

A: Yes. Both are ROHS3 Compliant and REACH Unaffected, maintaining equivalent regulatory compliance for industrial and commercial networking applications.
