MTJ-88ARX1-LP Equivalent & Substitute Parts

Part Overview

The MTJ-88ARX1-LP is a modular RJ45 connector jack manufactured by Adam Tech, designed for through-hole mounting with 90° right-angle orientation and shielding. This 8p8c (RJ45, Ethernet) connector features solder termination, phosphor bronze contacts with gold flash finish, and board lock functionality. The part is classified as obsolete, making identification of equivalent substitute parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MTJ-88ARX1-LP is determined by strict equivalence across the following critical parameters:

• Connector type: Jack
• Contact configuration: 8p8c (RJ45, Ethernet)
• Mounting method: Through hole
• Orientation: 90° angle (right)
• Termination method: Solder
• Shielding: Shielded
• Contact material and finish: Phosphor bronze with gold flash
• Housing material: Polybutylene terephthalate (PBT), glass filled
• Operating temperature range: -40°C ~ 85°C
• Regulatory compliance: ROHS3 compliant

The identified substitute parts MTJ-88ARX1-LD and MTJ-88ARX1-LG maintain full equivalence across all critical electrical and mechanical parameters. Variations exist only in packaging format and LED indicator color specifications, which do not affect core connector functionality or board-level compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both MTJ-88ARX1-LD and MTJ-88ARX1-LG are direct functional equivalents to the obsolete MTJ-88ARX1-LP. Selection between these two active alternatives should be based on the following criteria:

MTJ-88ARX1-LD is suitable for applications requiring dual green LED indicators and board guide functionality. This part maintains active product status with 863 units in current inventory.

MTJ-88ARX1-LG is suitable for applications requiring yellow and green LED indicator combination and board guide functionality. This part maintains active product status with significantly higher inventory availability at 5,879 units.

Both substitute parts are ROHS3 compliant, REACH unaffected, and carry identical electrical and mechanical specifications to the main part. The primary differentiators are LED color configuration and packaging format (tray versus bulk). Feature differences (board guide versus board lock) do not affect electrical performance or mechanical compatibility in standard through-hole PCB applications.

Frequently Asked Questions (FAQ)

Q: Can MTJ-88ARX1-LD and MTJ-88ARX1-LG be used interchangeably with MTJ-88ARX1-LP?

A: Yes. Both substitute parts maintain identical electrical and mechanical specifications across all critical parameters including connector type, contact configuration, mounting method, orientation, termination, shielding, contact materials, housing material, and operating temperature range. Differences in LED color and board feature type do not affect functional compatibility.

Q: What is the difference between board lock and board guide features?

A: Board lock and board guide are mechanical retention features on the connector housing. Both provide board-level stability. The MTJ-88ARX1-LP features board lock, while MTJ-88ARX1-LD and MTJ-88ARX1-LG feature board guide. These are functionally equivalent for standard through-hole PCB mounting applications.

Q: Why does the MTJ-88ARX1-LP show as obsolete?

A: The MTJ-88ARX1-LP is classified as obsolete, indicating it is no longer in active production. The substitute parts MTJ-88ARX1-LD and MTJ-88ARX1-LG are active products with current manufacturing and inventory support.

Q: Does packaging format affect connector performance?

A: No. The MTJ-88ARX1-LP is supplied in bulk packaging, while MTJ-88ARX1-LD and MTJ-88ARX1-LG are supplied in tray packaging. Packaging format affects logistics and handling only; it does not affect electrical or mechanical performance.

Q: Are all three parts ROHS3 compliant?

A: Yes. The MTJ-88ARX1-LP, MTJ-88ARX1-LD, and MTJ-88ARX1-LG are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Which substitute part has better inventory availability?

A: MTJ-88ARX1-LG has significantly higher inventory availability at 5,879 units compared to MTJ-88ARX1-LD at 863 units. Both are active products with current supply.
