Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RJSNEJ08N08 is determined by strict alignment of the following critical parameters:

Core Electrical & Mechanical Compatibility Parameters:

• Connector Type: Jack
• Number of Positions/Contacts: 8p8c (RJ45, Ethernet)
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination: Solder
• Shielding: Unshielded
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Housing Material: Thermoplastic

Compliance & Environmental Parameters:

• RoHS Status: RoHS Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part RJSAE508B08 satisfies all core compatibility parameters and maintains full compliance with RoHS and MSL requirements. Variations in contact finish thickness, operating temperature range, LED color options, and product status do not affect functional interchangeability for standard modular jack applications.

Engineering Selection Recommendations

RJSAE508B08 as Primary Substitute:

The RJSAE508B08 is the qualified substitute for RJSNEJ08N08 based on the following engineering criteria:

1. Functional Equivalence: All core electrical and mechanical parameters match exactly, including connector type, contact configuration, mounting method, orientation, and termination type.

2. Compliance Alignment: Both parts maintain RoHS Compliance and MSL Level 1 (Unlimited) ratings, ensuring regulatory and environmental compatibility.

3. Product Status Advantage: RJSAE508B08 carries Active product status, providing assured long-term availability and manufacturing support compared to the Obsolete status of RJSNEJ08N08.

4. Enhanced Operating Range: RJSAE508B08 supports an extended lower operating temperature limit (-55°C versus -40°C), providing broader environmental compatibility without compromising upper temperature performance.

5. Increased Contact Durability: The higher contact finish thickness (50.0µin versus 30.0µin) in RJSAE508B08 provides enhanced wear resistance and contact longevity.

6. Board Lock Feature: RJSAE508B08 includes a Board Lock feature, offering improved mechanical retention on PCB assemblies.

7. Export Classification: Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, maintaining consistent regulatory treatment.

Frequently Asked Questions (FAQ)

Q: Can RJSAE508B08 be used as a direct replacement for RJSNEJ08N08 in existing designs?

A: Yes. RJSAE508B08 is functionally equivalent to RJSNEJ08N08 across all critical parameters: connector type, contact configuration (8p8c RJ45), mounting method (through-hole), orientation (90° right-angle), termination (solder), and shielding (unshielded). Both parts use identical contact material (phosphor bronze), contact finish (gold), and housing material (thermoplastic).

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

A: The primary differences are: (1) Product Status—RJSAE508B08 is Active while RJSNEJ08N08 is Obsolete; (2) Operating Temperature Range—RJSAE508B08 extends to -55°C versus -40°C minimum; (3) Contact Finish Thickness—RJSAE508B08 provides 50.0µin versus 30.0µin; (4) Board Lock Feature—RJSAE508B08 includes this feature; (5) LED Color Options—RJSAE508B08 offers Red/Green versus Green/Red-Yellow; (6) Packaging—RJSAE508B08 is supplied in Tray format.

Q: Are there any compatibility concerns with packaging differences?

A: No. Packaging format (Tray for RJSAE508B08) does not affect electrical or mechanical compatibility. Packaging differences relate only to handling, storage, and logistics. The connector itself maintains identical form factor and interface specifications.

Q: Does the higher contact finish thickness affect performance?

A: No. The increased contact finish thickness (50.0µin in RJSAE508B08 versus 30.0µin in RJSNEJ08N08) enhances contact durability and wear resistance without affecting electrical performance or mechanical fit. This represents an improvement in long-term reliability.

Q: Are both parts RoHS compliant?

A: Yes. Both RJSNEJ08N08 and RJSAE508B08 are RoHS Compliant and carry MSL Level 1 (Unlimited) ratings, ensuring full regulatory compliance for restricted substance directives and moisture sensitivity requirements.

Q: What is the significance of the Board Lock feature in RJSAE508B08?

A: The Board Lock feature provides mechanical retention of the connector to the PCB, preventing accidental disconnection during handling or vibration. This is a functional enhancement that does not affect electrical compatibility but improves assembly robustness.

Q: Can RJSNEJ08N08 still be sourced?

A: RJSNEJ08N08 carries Obsolete product status. While inventory may be available from existing stock (683 Pcs noted), long-term availability is not assured. RJSAE508B08, with Active status and 983 Pcs in stock, provides assured supply continuity.
