Substitute Part Grouping Explanation

Substitution of the ARJM11B1-502-AB-ER2-T is determined by strict equivalence across the following critical parameters:

• Connector Type: RJ45 (8-core jack configuration)
• Mounting Type: Through Hole solder termination
• Orientation: 90° right-angle configuration
• Height Above Board: 0.535" (14.69mm)
• Shielding: Shielded construction
• Features: Board lock mechanism with LED indicators
• Electrical Performance: 10/100/1000 Base-T with AutoMDIX support
• Environmental Compliance: ROHS3 Compliant, MSL 1, REACH Unaffected

The substitute part ARJM11B1-502-AB-EW2 maintains identical electrical and mechanical specifications across all these parameters. The primary difference is packaging format (tray versus original packaging) and product status (active versus obsolete), with significantly higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The ARJM11B1-502-AB-EW2 is a direct functional equivalent to the ARJM11B1-502-AB-ER2-T across all electrical, mechanical, and environmental specifications. Selection of the substitute part is supported by:

• Identical compliance certifications: ROHS3, REACH Unaffected, EAR99 classification
• Matching environmental ratings: MSL 1 (unlimited moisture sensitivity level)
• Active product status with substantial inventory availability (236,614 units), ensuring supply chain continuity
• Identical series designation (ARJM11) and manufacturing source (Abracon LLC)
• No degradation in electrical performance, mechanical fit, or thermal operating range

The only non-functional differences are packaging format (tray) and product lifecycle status. These differences do not affect component performance, compatibility, or compliance in end-use applications.

Frequently Asked Questions (FAQ)

Q: Can ARJM11B1-502-AB-EW2 be used as a direct replacement for ARJM11B1-502-AB-ER2-T in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters including connector type, mounting configuration, orientation, height, shielding, and operating specifications. The substitute part maintains full compatibility with PCB layouts and circuit designs specified for the original part.

Q: What is the significance of the different packaging formats?

A: The original part uses unspecified packaging, while the substitute is supplied in tray packaging. This affects logistics and handling but does not impact component functionality, electrical performance, or mechanical compatibility. Tray packaging is standard for high-volume distribution.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected status, and EAR99 export classification. Environmental ratings (MSL 1, operating temperature -40°C to 85°C) are identical.

Q: Why is the original part listed as obsolete?

A: Product obsolescence reflects Abracon LLC's lifecycle management. The substitute part ARJM11B1-502-AB-EW2 is actively manufactured and maintained, providing long-term supply availability for this connector specification.

Q: Are the LED indicators identical between both parts?

A: Yes. Both parts feature dual LED indicators with green-yellow color configuration, providing identical status indication functionality.

Q: What are the key parameters that determine substitutability for this connector type?

A: Substitutability is determined by: RJ45 connector type, 8-core jack configuration, through-hole solder termination, 90° right-angle orientation, 0.535" board height, shielded construction, board lock feature, gold contact finish, and 10/100/1000 Base-T electrical performance with AutoMDIX support.
