TM5RJ3-88 Equivalent & Substitute Parts

Part Overview

The TM5RJ3-88 is a modular jack connector manufactured by Hirose Electric Co Ltd, designed for 8-position 8-contact (8p8c/RJ45 Ethernet) applications. This connector features a 90° right-angle orientation with through-hole solder termination and unshielded construction. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TM5RJ3-88 is determined by strict alignment of the following critical parameters:

• Connector type (Jack)
• Contact configuration (8p8c/RJ45 Ethernet)
• Orientation (90° right-angle)
• Mounting method (Through hole)
• Termination type (Solder)
• Shielding classification (Unshielded)
• Housing and contact materials (PBT, Phosphor Bronze, Gold finish)
• Mechanical features (Board Lock, Keyed, Panel Stops, Up tab direction)

The TM5RJ1-88(50) qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Packaging differences (tray versus bulk) do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The TM5RJ1-88(50) is the designated substitute for the obsolete TM5RJ3-88. Both connectors share identical electrical and mechanical specifications within the TM-DS series. The substitute part offers an extended operating temperature range (-25°C ~ 80°C versus -25°C ~ 60°C) and RoHS compliance status, providing improved regulatory alignment for new designs and system upgrades. Packaging format (tray) does not affect functional performance or PCB integration.

Frequently Asked Questions (FAQ)

Q: Can TM5RJ1-88(50) be used as a direct replacement for TM5RJ3-88 in existing designs?

A: Yes. Both connectors are functionally identical in electrical performance, mechanical fit, and PCB mounting. The substitute part maintains the same 8p8c contact configuration, 90° right-angle orientation, through-hole solder termination, and mechanical features (board lock, keyed design, panel stops).

Q: What is the difference between TM5RJ3-88 and TM5RJ1-88(50)?

A: The primary differences are packaging format (bulk versus tray) and operating temperature range. TM5RJ1-88(50) supports -25°C ~ 80°C compared to -25°C ~ 60°C for the original part. Additionally, TM5RJ1-88(50) is RoHS compliant while TM5RJ3-88 is not.

Q: Are there any compatibility concerns with PCB layout or footprint?

A: No. Both connectors use identical through-hole mounting specifications and mechanical dimensions. Existing PCB designs require no modification for component substitution.

Q: Does the extended temperature range of TM5RJ1-88(50) affect cost or lead time?

A: Lead time and availability are determined by current inventory levels. TM5RJ1-88(50) currently has 9,328 units in stock compared to 813 units for TM5RJ3-88.

Q: Is RoHS compliance a requirement for my application?

A: RoHS compliance is mandatory for products sold in the European Union and certain other markets. TM5RJ1-88(50) meets RoHS requirements while TM5RJ3-88 does not. Regulatory requirements should be evaluated based on target markets and end-use applications.
