Substitute Part Grouping Explanation

Substitution eligibility for the ARJM11A1-576-KB-EW2 is determined by strict alignment of 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, MSL 1 rating, operating range -40°C to 85°C
• Functional Features: LED indicators (Green, Orange-Yellow), board lock or equivalent retention mechanism

The substitute part 2250015-3 (TRP Connector B.V., MagJack® series) meets all critical substitution criteria and maintains functional and electrical equivalence for direct replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the 2250015-3 be used as a direct replacement for the ARJM11A1-576-KB-EW2?

A: Yes. Both components share identical connector type (RJ45), port configuration (1 port), electrical performance (10/100/1000 Base-T, AutoMDIX), mounting method (through hole), orientation (90° right angle), and termination type (solder). Physical height variance (0.535" vs 0.539") is within standard PCB layout tolerance.

Q: What is the primary reason for substitution?

A: The ARJM11A1-576-KB-EW2 is classified as Obsolete. The 2250015-3 is an Active product with equivalent specifications and ongoing manufacturing support.

Q: Are there differences in retention features between these parts?

A: The ARJM11A1-576-KB-EW2 includes Board Lock functionality, while the 2250015-3 features Board Guide. Both provide mechanical retention for PCB mounting; design verification is required if specific retention geometry is critical to the application.

Q: Do both parts support the same LED indicator configuration?

A: Yes. Both components provide Green and Orange-Yellow LED indicators for link and activity status in 10/100/1000 Base-T applications.

Q: Are there compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH Unaffected, classified as EAR99, and share identical HTSUS coding (8536.69.4040).

Q: What is the packaging difference?

A: The ARJM11A1-576-KB-EW2 packaging is not specified in available data. The 2250015-3 is supplied in Tray packaging.
