RJSNEJ38TA8 Equivalent & Substitute Parts

Part Overview

The RJSNEJ38TA8 is a Jack Modular Connector with 8p8c (RJ45, Ethernet) configuration, featuring 90° right-angle orientation and shielding with EMI finger. Manufactured by Amphenol ICC (Commercial Products), this through-hole solder-terminated connector is designed for network and telecommunications applications requiring board-level integration with mechanical stability.

The RJSNEJ38TA8 carries an Obsolete product status. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RJSNEJ38TA8 is determined by strict alignment of the following critical parameters:

Core Functional Parameters (Must Match Exactly):

• Connector Type: Jack
• Number of Positions/Contacts: 8p8c (RJ45, Ethernet)
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination: Solder
• Shielding: Shielded, EMI Finger

Material & Environmental Parameters (Must Match or Exceed):

• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Housing Material: Thermoplastic
• Operating Temperature Range: Minimum -40°C ~ 85°C
• RoHS Compliance: Required

The RJSAE538B08 satisfies all core functional parameters and material specifications. Variations in contact finish thickness, LED color options, and operating temperature upper range do not preclude substitution when the minimum environmental requirements are met.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538B08 is a direct functional substitute for the RJSNEJ38TA8. Both connectors are RoHS Compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings, ensuring compliance with environmental and regulatory requirements.

The RJSAE538B08 offers enhanced specifications in two areas: contact finish thickness is increased to 50.0µin (1.27µm) compared to 30.0µin (0.76µm), and the operating temperature range extends to -55°C, providing greater margin for low-temperature applications. These enhancements do not introduce incompatibility with designs specified for the RJSNEJ38TA8.

The transition from the Obsolete RJSNEJ38TA8 to the Active RJSAE538B08 is supported by identical core electrical and mechanical specifications, identical contact material and finish composition, and equivalent board-level integration characteristics. The RJSAE538B08 is available in Tray packaging with 863 units in current inventory.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE538B08 be used as a direct replacement for the RJSNEJ38TA8 in existing PCB designs?

A: Yes. Both connectors share identical connector type, pin configuration (8p8c RJ45), mounting method (through-hole solder), orientation (90° right-angle), and shielding architecture (EMI finger). PCB footprints and solder pad layouts are compatible.

Q: What is the significance of the contact finish thickness difference?

A: The RJSAE538B08 provides 50.0µin (1.27µm) gold plating compared to 30.0µin (0.76µm) on the RJSNEJ38TA8. Increased plating thickness enhances contact durability and corrosion resistance, representing an improvement over the original specification.

Q: Does the extended operating temperature range of the RJSAE538B08 affect compatibility?

A: No. The RJSAE538B08 operating range of -55°C ~ 85°C encompasses the RJSNEJ38TA8 range of -40°C ~ 85°C. Extended low-temperature capability does not introduce incompatibility with designs specified for the narrower range.

Q: Are there packaging differences between these connectors?

A: The RJSNEJ38TA8 packaging is not specified in available data. The RJSAE538B08 is supplied in Tray packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What is the LED color difference between these parts?

A: The RJSNEJ38TA8 features Red LED color. The RJSAE538B08 offers Red and Green LED options. LED color selection does not affect electrical or mechanical substitution compatibility.

Q: Are both connectors RoHS compliant?

A: Yes. Both the RJSNEJ38TA8 and RJSAE538B08 are RoHS Compliant, meeting environmental and regulatory requirements for restricted substance use.
