TM3RA-88 Equivalent & Substitute Parts

Part Overview

The TM3RA-88 is a modular jack connector (8P8C/RJ45) manufactured by Hirose Electric Co Ltd, designed for vertical through-hole mounting with solder termination. This connector features an unshielded design with board lock and panel stops, utilizing phosphor bronze contacts with gold finish and PBT housing. The TM3RA-88 is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TM3RA-88 is determined by strict alignment of the following critical parameters:

• Connector Type: Jack
• Number of Positions/Contacts: 8P8C (RJ45, Ethernet)
• Mounting Type: Through Hole
• Orientation: Vertical
• Termination: Solder
• Shielding: Unshielded
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Housing Material: PBT or compatible polymers
• Features: Board Lock, Panel Stops
• Tab Direction: User Selectable
• MSL Rating: 1 (Unlimited)

Two substitute parts meet these criteria: TM3RA-88(50) from Hirose Electric Co Ltd and 5520259-4 from TE Connectivity AMP Connectors. Both maintain identical mechanical and electrical interface specifications while differing in product status, compliance certifications, and operating temperature ranges.

Parameter Comparison

Engineering Selection Recommendations

TM3RA-88(50) is the direct manufacturer equivalent from Hirose Electric Co Ltd. This part maintains identical mechanical and electrical specifications while offering active product status and RoHS3 compliance. The TM3RA-88(50) is packaged in trays and represents the current production variant of the TM3RA-88 series.

5520259-4 from TE Connectivity AMP Connectors is a cross-manufacturer substitute that meets all critical interface parameters. This part provides an extended operating temperature range (-40°C ~ 85°C) compared to the original specification (-25°C ~ 60°C) and carries RoHS compliance certification. The 5520259-4 is designated as Cat3 rated and includes a specified contact finish thickness of 50.0µin (1.27µm).

For new designs or component replenishment, TM3RA-88(50) is recommended as the primary substitute due to series continuity with the original part. The 5520259-4 is suitable for applications requiring extended temperature performance or cross-manufacturer sourcing flexibility.

Frequently Asked Questions (FAQ)

Q: Can TM3RA-88(50) be used as a direct replacement for TM3RA-88?

A: Yes. TM3RA-88(50) maintains identical connector type, contact count, mounting configuration, termination method, and mechanical interface specifications. The primary difference is product status (active versus obsolete) and RoHS3 compliance certification.

Q: What are the key differences between TM3RA-88(50) and 5520259-4?

A: Both parts share identical mechanical and electrical interface specifications. The primary differences are manufacturer (Hirose versus TE Connectivity), operating temperature range (TM3RA-88(50): -25°C ~ 60°C; 5520259-4: -40°C ~ 85°C), and housing material composition (5520259-4 includes polyester in addition to PBT).

Q: Is the TM3RA-88 still available for procurement?

A: The TM3RA-88 is classified as obsolete. Current inventory exists (810 pcs reported), but long-term availability is not assured. TM3RA-88(50) and 5520259-4 are both active products with established supply chains.

Q: What is the significance of the packaging difference between TM3RA-88 and TM3RA-88(50)?

A: The original TM3RA-88 packaging is not specified in available data. TM3RA-88(50) is supplied in trays, which is standard for active production. Packaging does not affect connector functionality or interface compatibility.

Q: Are there compliance considerations when substituting the TM3RA-88?

A: The original TM3RA-88 is RoHS non-compliant. Both substitute parts (TM3RA-88(50) and 5520259-4) carry RoHS compliance certifications, making them suitable for applications with RoHS requirements. All three parts are REACH unaffected or vendor undefined, and all carry EAR99 ECCN classification.

Q: Does the Cat3 rating on 5520259-4 affect compatibility?

A: The Cat3 rating on 5520259-4 indicates category 3 performance classification for Ethernet applications. This is an additional specification that does not conflict with the mechanical and electrical interface requirements of the TM3RA-88. Compatibility is maintained for all specified parameters.
