0826-1M1T-43-F Equivalent & Substitute Parts

Part Overview

The 0826-1M1T-43-F is a 1-port RJ45 through-hole modular connector manufactured by Bel Fuse Inc. under the MagJack® series. This connector supports 10/100/1000 Base-T Ethernet with AutoMDIX functionality and features a 90° right-angle orientation with dual LED indicators (green and orange). The part is currently active in production with 1108 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct replacement in applications requiring identical form factor, termination method, and performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

The JK0-0136NL from Pulse Electronics qualifies as a substitute for the 0826-1M1T-43-F based on alignment of critical electrical and mechanical parameters. Both connectors share identical specifications for connector type (RJ45), port count (1), mounting method (through hole), orientation (90° right angle), termination (solder), application support (10/100/1000 Base-T with AutoMDIX), core count (8), shielding configuration (shielded with EMI finger), and operating temperature range (0°C ~ 70°C). Both maintain gold contact finish and comply with RoHS standards. Height above board measurements differ marginally (0.536" vs 0.546"), which remains within acceptable mechanical tolerance for PCB layout compatibility. Contact finish thickness and shield material composition vary between manufacturers but do not affect functional interchangeability in the specified application.

Parameter Comparison

Engineering Selection Recommendations

Both the 0826-1M1T-43-F and JK0-0136NL maintain active product status and full regulatory compliance (RoHS, REACH, EAR99). Selection between these parts should be based on availability and supply chain requirements. The 0826-1M1T-43-F (Bel Fuse MagJack® series) currently maintains 1108 units in stock, while the JK0-0136NL (Pulse Electronics PULSEJACK™ JK0 series) has higher inventory availability at 3836 units. Both connectors satisfy identical electrical performance requirements and mechanical form factor constraints. The marginal height difference (0.01") is negligible for standard PCB layout applications. Contact material composition (copper alloy vs. phosphor bronze) and contact finish thickness variations do not impact functional performance within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the JK0-0136NL directly replace the 0826-1M1T-43-F in existing designs?

A: Yes. Both connectors share identical electrical specifications, mounting method, orientation, and termination type. The 0.01" height difference is within standard PCB tolerance and does not affect component placement or signal integrity.

Q: Are there differences in LED indicator specifications between these parts?

A: The 0826-1M1T-43-F features green and orange LEDs, while the JK0-0136NL features yellow and green LEDs. LED color selection should be verified against application requirements if visual indication is critical to system design.

Q: Do both parts support the same Ethernet standards?

A: Yes. Both connectors support 10/100/1000 Base-T with AutoMDIX functionality, enabling automatic MDI/MDI-X detection and crossover.

Q: What is the significance of the contact material difference?

A: The 0826-1M1T-43-F uses copper alloy contacts while the JK0-0136NL uses phosphor bronze. Both materials with gold plating provide equivalent electrical performance and corrosion resistance for the specified operating temperature range.

Q: Are packaging and MSL ratings identical?

A: Both parts ship in trays. The 0826-1M1T-43-F lists MSL as not applicable, while the JK0-0136NL specifies MSL 1 (unlimited). This difference does not affect component functionality but may impact storage and handling procedures based on facility protocols.

Q: Which part should be selected for new designs?

A: Selection should prioritize supply chain availability and lead time. Both parts meet identical functional and compliance requirements. The JK0-0136NL currently has higher inventory levels (3836 units vs. 1108 units).
