Engineering Selection Recommendations

0826-1X1T-M1-F (Bel Fuse Inc.)

This part is a direct equivalent to the 0826-1X1T-80-F. Both are manufactured by Bel Fuse Inc. within the MagJack® series and share identical electrical specifications, mounting characteristics, and regulatory compliance (ROHS3). The parts differ only in housing material composition (Polyamide PA46 vs. Polyamide PA) and contact finish thickness specification. Both parts are active in production with full inventory availability. Selection between these two parts is determined by specific housing material requirements for the application.

JK0-0145NL (Pulse Electronics)

This part is functionally compatible as a substitute for the 0826-1X1T-80-F. Both support 10/100/1000 Ethernet with AutoMDIX, feature identical mounting orientation, solder termination, and shielded EMI design. The JK0-0145NL operates within the same temperature range and maintains RoHS compliance. Differences include manufacturer (Pulse Electronics vs. Bel Fuse Inc.), contact material (Phosphor Bronze vs. Copper Alloy), contact finish thickness (15.0µin vs. 50.0µin), shield material (Brass vs. Copper Alloy), and height above board (0.546" vs. 0.536"). The JK0-0145NL is classified as 10/100/1000 Base-TX rather than Base-T. These variations do not affect functional compatibility within the specified electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can the 0826-1X1T-M1-F be used as a direct replacement for the 0826-1X1T-80-F?

A: Yes. Both parts are manufactured by Bel Fuse Inc., share identical electrical and mechanical specifications, and are both ROHS3 compliant. The housing material composition differs (PA46 vs. PA), but this does not affect functional compatibility for standard PCB integration applications.

Q: What are the key differences between the 0826-1X1T-80-F and JK0-0145NL?

A: The primary differences are manufacturer (Bel Fuse Inc. vs. Pulse Electronics), contact material (Copper Alloy vs. Phosphor Bronze), contact finish thickness (50.0µin vs. 15.0µin), shield material (Copper Alloy vs. Brass), and height above board (0.536" vs. 0.546"). Both parts support 10/100/1000 Ethernet with AutoMDIX and maintain compatible electrical performance within the specified operating parameters.

Q: Are all three parts suitable for the same PCB footprint?

A: The 0826-1X1T-80-F and 0826-1X1T-M1-F share identical height above board (0.536"). The JK0-0145NL has a slightly greater height (0.546"), which may require PCB layout verification to ensure clearance compatibility. All three parts maintain the same through-hole mounting orientation and solder termination method.

Q: Do all substitute parts meet the same regulatory requirements?

A: The 0826-1X1T-80-F and 0826-1X1T-M1-F are both ROHS3 compliant. The JK0-0145NL is RoHS compliant. All three parts are REACH unaffected and classified as EAR99 for export control purposes.

Q: What is the inventory status for each part?

A: The 0826-1X1T-80-F has 1064 units in stock. The 0826-1X1T-M1-F has 19154 units in stock. The JK0-0145NL has 1313 units in stock. All parts are listed as active products.
