Substitute Part Grouping Explanation

Substitution of the ARJM11C7-576-KB-EW2 is determined by strict equivalence across the following critical parameters:

Connector Type & Port Configuration: RJ45, single port
Electrical Performance: 10/100/1000 Base-T with AutoMDIX support
Physical Form Factor: Through hole mounting, 90° right-angle orientation, solder termination
Signal Integrity: 8-core jack with shielded construction and EMI finger protection
Environmental Compliance: ROHS3 compliance, REACH unaffected status, EAR99 classification

The substitute part 2250013-7 (TRP Connector B.V., MagJack® series) meets all critical functional and compliance requirements. Minor variations in operating temperature range, contact finish thickness, and housing materials do not preclude substitution when the primary electrical and mechanical interfaces are preserved.

Engineering Selection Recommendations

The 2250013-7 (TRP Connector B.V.) is the qualified substitute for the obsolete ARJM11C7-576-KB-EW2. Selection is based on the following engineering criteria:

Functional Equivalence: Both connectors provide identical RJ45 single-port, 10/100/1000 Base-T with AutoMDIX functionality, through-hole solder termination, and 90° right-angle orientation. The 8-core jack configuration with shielded EMI finger protection ensures signal integrity parity.

Compliance & Certification: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current production and distribution.

Physical Compatibility: The height variance of 0.004" (0.10mm) between the two connectors is within typical PCB layout tolerances and does not impact board-level integration.

Operating Temperature Consideration: The substitute part operates within 0°C ~ 70°C, which is narrower than the original -40°C ~ 85°C range. Applications requiring extended low-temperature operation below 0°C or sustained operation above 70°C must evaluate thermal requirements against the substitute's specifications.

Contact Finish Durability: The substitute provides enhanced contact finish thickness (50.0µin vs. 6.00µin), which may improve long-term contact reliability and mating cycle performance.

Frequently Asked Questions (FAQ)

Q: Can the 2250013-7 be used as a direct replacement in existing designs?

A: Yes, for applications operating within 0°C ~ 70°C. The connector maintains identical electrical performance, pinout, and physical form factor. PCB layouts designed for the ARJM11C7-576-KB-EW2 require no modification for the 2250013-7 substitution.

Q: What is the impact of the operating temperature range difference?

A: The substitute operates within 0°C ~ 70°C versus the original -40°C ~ 85°C. Applications requiring operation below 0°C or sustained operation above 70°C must confirm thermal compatibility with the substitute's specifications or identify alternative components.

Q: Are there differences in contact finish that affect performance?

A: The substitute provides thicker gold plating (50.0µin vs. 6.00µin), which exceeds the original specification. This enhancement typically improves contact durability and mating cycle performance without introducing compatibility issues.

Q: Is the height difference of 0.004" significant for PCB layout?

A: No. The 0.004" (0.10mm) variance is within standard PCB layout tolerances and does not require design modifications for board-level integration.

Q: What is the availability status of the substitute part?

A: The 2250013-7 is actively manufactured by TRP Connector B.V. with 850 units in current stock, ensuring supply continuity for production requirements.

Q: Are both parts certified for the same regulatory standards?

A: Yes. Both the ARJM11C7-576-KB-EW2 and 2250013-7 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronics manufacturing and distribution.
