Engineering Selection Recommendations

The 08B0-1X1T-36-F from Bel Fuse Inc. is the designated substitute for the obsolete ARJM11A1-007-KB-EW2. Selection rationale is based on:

Product Status: The ARJM11A1-007-KB-EW2 is obsolete with no active manufacturing support. The 08B0-1X1T-36-F maintains active product status with continuous manufacturing availability (88,964 units in current inventory versus 877 units for the original part).

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH Unaffected status, satisfying current environmental and regulatory requirements.

Functional Equivalence: All critical electrical and mechanical parameters align, including connector type, port configuration, network application support (10/100 Base-T with AutoMDIX), mounting method, orientation, and operating temperature range.

Physical Compatibility: Height above board measurements are within 0.004" (0.1mm) tolerance, ensuring PCB layout compatibility for through-hole mounting applications.

Frequently Asked Questions (FAQ)

Q: Can the 08B0-1X1T-36-F be used as a direct replacement for the ARJM11A1-007-KB-EW2?

A: Yes. Both components share identical connector type (RJ45), port count (1), network application support (10/100 Base-T with AutoMDIX), mounting method (Through Hole), orientation (90° Right), termination type (Solder), LED configuration (Green, Orange-Yellow), shielding (Shielded with EMI Finger), and operating temperature range (-40°C to 85°C). Physical height variation is 0.004" (0.1mm), which is within standard PCB layout tolerances.

Q: What is the primary reason for substitution?

A: The ARJM11A1-007-KB-EW2 is classified as obsolete with no active manufacturing support. The 08B0-1X1T-36-F is an active product with current production and significantly higher inventory availability, ensuring long-term supply chain reliability.

Q: Are there packaging differences between these components?

A: The ARJM11A1-007-KB-EW2 packaging is not specified in available documentation. The 08B0-1X1T-36-F is supplied in Tray packaging. Confirm packaging requirements with your procurement department for inventory management and handling procedures.

Q: Do both components meet current regulatory standards?

A: Yes. Both the ARJM11A1-007-KB-EW2 and 08B0-1X1T-36-F are ROHS3 compliant and REACH Unaffected, satisfying current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: Are there any mechanical differences that could affect PCB layout?

A: Height above board measurements differ by 0.004" (0.1mm): ARJM11A1-007-KB-EW2 at 0.535" (14.69mm) versus 08B0-1X1T-36-F at 0.531" (13.49mm). This variation is within standard manufacturing tolerances and does not require PCB redesign for through-hole mounting applications.
