RJSNEJ08M08

Part Overview

The RJSNEJ08M08 is a Jack Modular Connector, 8p8c (RJ45, Ethernet) with 90° right-angle unshielded configuration, designed for through-hole solder termination. This connector is rated for operating temperatures from -40°C to 85°C and features phosphor bronze contacts with gold plating. The part is currently listed as obsolete, making the identification of suitable substitute parts essential for continued system support and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RJSNEJ08M08 is determined by strict equivalence across the following critical parameters:

• Connector Type & Positions: Both must be Jack, 8p8c (RJ45, Ethernet)
• Orientation & Mounting: 90° right-angle orientation with through-hole mounting
• Termination Method: Solder termination required
• Electrical Shielding: Unshielded configuration
• Contact Material & Finish: Phosphor bronze with gold plating
• Housing Material: Thermoplastic construction
• Compliance: RoHS compliant status

The RJSAE508708 meets all critical substitution criteria. Differences in contact finish thickness, operating temperature ceiling, LED color, and additional features (board lock) do not preclude substitution, as these parameters remain within acceptable functional ranges for the specified application category.

Engineering Selection Recommendations

Primary Substitute: RJSAE508708

The RJSAE508708 is the qualified substitute for the obsolete RJSNEJ08M08. Both connectors maintain full electrical and mechanical compatibility, sharing identical connector configuration, contact material composition, and termination method. The RJSAE508708 is currently in active production status, ensuring continued availability and supply chain stability.

The RJSAE508708 provides an expanded operating temperature range (-55°C to 85°C versus -40°C to 85°C), enhanced contact durability through increased gold plating thickness (50.0µin versus 30.0µin), and integrated board lock feature. Both components maintain RoHS compliance and identical MSL ratings. The substitute part is supplied in tray packaging, supporting standard manufacturing and assembly workflows.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE508708 be used as a direct replacement for the RJSNEJ08M08?

A: Yes. Both connectors are functionally equivalent RJ45 jack modules with 90° right-angle through-hole solder termination, unshielded configuration, and thermoplastic housing. The core electrical and mechanical parameters are identical.

Q: What are the key differences between these two parts?

A: The RJSAE508708 features a thicker gold contact finish (50.0µin versus 30.0µin), an extended low-temperature operating range (-55°C versus -40°C minimum), an integrated board lock feature, and different LED color options (Red-Green versus Red-Yellow). Packaging is also different: tray versus the original specification.

Q: Does the board lock feature on the RJSAE508708 affect compatibility?

A: The board lock feature is an additional mechanical benefit that does not compromise compatibility. It provides enhanced retention during PCB assembly and field service operations without altering electrical performance.

Q: Are there any temperature-related limitations for substitution?

A: No. The RJSAE508708 extends the low-temperature operating ceiling from -40°C to -55°C, providing a broader operational envelope. Both parts operate identically within the standard -40°C to 85°C range.

Q: What is the impact of different contact finish thickness?

A: The increased gold plating thickness (50.0µin) on the RJSAE508708 enhances contact durability and longevity, providing extended service life compared to the thinner plating (30.0µin) of the original part. Both finishes meet RJ45 connector standards.

Q: Are both parts RoHS compliant?

A: Yes. Both the RJSNEJ08M08 and RJSAE508708 are RoHS compliant with MSL rating 1 (unlimited moisture sensitivity level), meeting regulatory requirements for both commercial and industrial applications.

Q: What packaging options are available?

A: The RJSNEJ08M08 was originally supplied without specified packaging. The RJSAE508708 is supplied in tray packaging, standard for modular connector component handling and automated assembly workflows.
