Substitute Part Grouping Explanation

Substitution of the ARJM11D7-130-KB-ER2-T is based on strict equivalence across the following critical parameters:

Connector Type & Port Configuration: RJ45, single port
Mechanical Compatibility: Through hole mounting, 90° right-angle orientation, 0.543" (13.80mm) height above board, board lock feature, upward tab direction
Electrical & Functional Specifications: 10/100 Base-T with AutoMDIX and PoE support, 4 cores per jack, shielded construction
Environmental & Compliance Requirements: Operating temperature range -40°C ~ 85°C, ROHS3 compliance, MSL 1, gold contact finish

The ARJM11D7-114-KB-ER2-T meets all these criteria and is classified as an MFR (Manufacturer) Recommended substitute. The primary distinction is product status: the original part is Obsolete, while the substitute is Active.
