Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RJSNEJ08808 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Jack
• Contact Configuration: 8p8c (RJ45, Ethernet)
• Orientation: 90° Angle (Right)
• Mounting Type: Through Hole
• Termination Method: Solder
• Shielding: Unshielded
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Housing Material: Thermoplastic
• RoHS Compliance: Compliant
• Moisture Sensitivity Level: 1

The RJSAE508808 meets all mandatory matching parameters and qualifies as a direct substitute. The primary distinction is product status: RJSNEJ08808 is obsolete, while RJSAE508808 is active in production.

Engineering Selection Recommendations

RJSAE508808 as Primary Substitute:

The RJSAE508808 is the qualified substitute for RJSNEJ08808 based on functional and electrical equivalence. Both parts are RoHS compliant and share identical connector architecture, contact configuration, and termination characteristics.

Differentiating Factors:

1. Product Status: RJSAE508808 is active in production, ensuring long-term availability and supply chain continuity. RJSNEJ08808 is obsolete and subject to discontinuation.

2. Operating Temperature Range: RJSAE508808 extends the lower operating limit to -55°C compared to -40°C for RJSNEJ08808, providing enhanced performance in cold environments.

3. Contact Finish Thickness: RJSAE508808 provides 50.0µin (1.27µm) gold plating versus 30.0µin (0.76µm) on RJSNEJ08808, offering increased contact durability and wear resistance.

4. Board Lock Feature: RJSAE508808 includes a board lock mechanism, providing mechanical retention enhancement not present in RJSNEJ08808.

5. Packaging: RJSAE508808 is supplied in tray packaging, standard for production environments.

Frequently Asked Questions (FAQ)

Q: Can RJSAE508808 directly replace RJSNEJ08808 in existing designs?

A: Yes. Both connectors share identical electrical and mechanical specifications for the core connector interface: 8p8c RJ45 configuration, 90° right-angle orientation, through-hole solder termination, unshielded design, and phosphor bronze gold-plated contacts. The RJSAE508808 includes additional features (board lock, extended temperature range, thicker gold plating) that do not compromise backward compatibility.

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

A: The RJSAE508808 provides 50.0µin (1.27µm) gold plating compared to 30.0µin (0.76µm) on RJSNEJ08808. Thicker gold plating extends contact life by reducing wear during mating cycles and provides superior corrosion resistance. This is a performance enhancement with no negative impact on compatibility.

Q: Does the board lock feature on RJSAE508808 affect PCB layout?

A: The board lock feature provides mechanical retention to the PCB. PCB layout compatibility depends on specific board design. Verify that mounting hole patterns and mechanical envelope accommodate the board lock mechanism in your application.

Q: Are there temperature-related constraints when substituting?

A: RJSAE508808 operates from -55°C to 85°C, while RJSNEJ08808 operates from -40°C to 85°C. RJSAE508808 supports the full temperature range of RJSNEJ08808 and extends capability to lower temperatures. No constraint exists for applications within the original -40°C to 85°C range.

Q: What packaging considerations apply to RJSAE508808?

A: RJSAE508808 is supplied in tray packaging, standard for production assembly. Confirm that your procurement and assembly processes accommodate tray packaging format.

Q: Are both parts RoHS compliant?

A: Yes. Both RJSNEJ08808 and RJSAE508808 are RoHS compliant and carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.
