Substitute Part Grouping Explanation

The ARJM11B1-634-AB-EW2 can be substituted with ARJM11B1-502-AB-EW2 based on electrical and mechanical parameter equivalence. Both parts share identical specifications across all critical functional parameters: RJ45 connector type, single port configuration, through-hole mounting, 90° right-angle orientation, solder termination, identical board height, matching LED indicators, 8-core jack configuration, shielded design, board lock feature, downward tab direction, gold contact finish, and identical operating temperature range. Both components maintain ROHS3 compliance and MSL 1 rating. The primary distinction is product status: ARJM11B1-634-AB-EW2 is Obsolete, while ARJM11B1-502-AB-EW2 is Active with significantly higher inventory availability (236,614 units versus 632 units).

Parameter Comparison

Engineering Selection Recommendations

ARJM11B1-502-AB-EW2 is the direct functional equivalent for ARJM11B1-634-AB-EW2. Selection of the substitute part is justified by: (1) Active product status ensuring long-term availability and supply chain continuity, (2) Identical electrical and mechanical specifications across all functional parameters, (3) Equivalent compliance certifications (ROHS3, REACH Unaffected, EAR99), and (4) Substantially higher inventory availability. Both components are suitable for 10/100/1000 Base-T Ethernet applications with AutoMDIX support. The packaging difference (Tray for substitute versus unspecified for main part) does not affect functional performance or PCB integration.

Frequently Asked Questions (FAQ)

Q: Are ARJM11B1-634-AB-EW2 and ARJM11B1-502-AB-EW2 electrically identical?

A: Yes. Both components share identical electrical specifications including RJ45 connector type, 8-core jack configuration, gold contact finish with 6.00µin thickness, shielded design, and 10/100/1000 Base-T AutoMDIX support.
