RJ45-8N-B Equivalent & Substitute Parts

Part Overview

The RJ45-8N-B is a modular jack connector manufactured by TE Connectivity Corcom Filters, designed for 8-position 8-contact (8p8c) Ethernet applications. This connector features a 90° right-angle orientation with through-hole solder termination and unshielded construction. The product is classified as obsolete, necessitating identification of active equivalent components to maintain design continuity and ensure ongoing component availability for new production and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RJ45-8N-B is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Jack
• Number of Positions/Contacts: 8p8c (RJ45, Ethernet)
• Orientation: 90° Angle (Right)
• Mounting Type: Through Hole
• Termination: Solder
• Shielding: Unshielded
• Contact Material: Phosphor Bronze
• Contact Finish: Gold at 50.0µin (1.27µm)
• Tab Direction: Down

The FRJAE448 manufactured by Amphenol ICC (Commercial Products) satisfies all mandatory matching parameters. Both connectors are functionally equivalent for 8p8c RJ45 Ethernet jack applications with identical electrical and mechanical interfaces. The primary distinction is product status: RJ45-8N-B is obsolete while FRJAE448 is active, with higher inventory availability (3006 units versus 839 units).

Parameter Comparison

Engineering Selection Recommendations

The FRJAE448 is the direct functional equivalent for the obsolete RJ45-8N-B. Both connectors meet identical electrical and mechanical specifications for 8p8c RJ45 Ethernet jack applications with through-hole solder termination and 90° right-angle orientation.

Compliance Status: Both components are RoHS compliant and classified under identical ECCN (EAR99) and HTSUS (8536.69.4040) codes, ensuring regulatory equivalence for procurement and export purposes.

Availability Advantage: The FRJAE448 is currently active with 3006 units in stock, compared to 839 units of the obsolete RJ45-8N-B. This availability differential supports long-term supply chain continuity.

Material Consideration: The RJ45-8N-B housing is specified as polyamide (PA) nylon glass-filled, while the FRJAE448 housing is thermoplastic. Both materials provide equivalent mechanical performance for modular connector applications. The FRJAE448 additionally specifies an operating temperature range of -55°C to 85°C, which the RJ45-8N-B does not explicitly define.

Feature Variance: The RJ45-8N-B includes panel stops as an additional feature not listed for the FRJAE448. This distinction does not affect electrical or mechanical compatibility for standard through-hole PCB mounting applications.

Frequently Asked Questions (FAQ)

Q: Can the FRJAE448 directly replace the RJ45-8N-B in existing designs?

A: Yes. Both connectors are functionally equivalent for 8p8c RJ45 Ethernet jack applications. They share identical contact configurations, solder termination, 90° right-angle orientation, and through-hole mounting specifications. PCB footprints and electrical performance are compatible.

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

A: The RJ45-8N-B uses polyamide (PA) nylon glass-filled housing, while the FRJAE448 uses thermoplastic housing. Both materials provide adequate mechanical strength and dimensional stability for modular connector applications. The material difference does not affect electrical performance or mechanical compatibility.

Q: Does the FRJAE448 include the panel stops feature of the RJ45-8N-B?

A: The FRJAE448 is specified with board lock and filter features. Panel stops are listed only for the RJ45-8N-B. If panel stops are a critical design requirement, this distinction should be evaluated against application-specific mounting constraints.

Q: Are both connectors RoHS compliant?

A: Yes. The RJ45-8N-B is ROHS3 compliant, and the FRJAE448 is RoHS compliant. Both meet regulatory requirements for lead-free and restricted substance compliance.

Q: What is the packaging difference between these connectors?

A: The RJ45-8N-B packaging is not specified in the provided data. The FRJAE448 is supplied in tray packaging. Packaging format should be confirmed with the supplier based on procurement volume and handling requirements.

Q: Are the contact finish specifications identical?

A: Yes. Both connectors feature gold-plated phosphor bronze contacts with a finish thickness of 50.0µin (1.27µm), ensuring equivalent electrical contact resistance and corrosion resistance.

Q: What is the inventory status for each connector?

A: The RJ45-8N-B has 839 units in stock and is classified as obsolete. The FRJAE448 has 3006 units in stock and is classified as active. The FRJAE448 provides superior long-term availability for ongoing production requirements.
