RJSNE508508 Modular Connector Jack 8P8C RJ45 Equivalent & Substitute Parts

Part Overview

The RJSNE508508 is a Jack Modular Connector with 8 positions and 8 contacts (8P8C, RJ45 Ethernet standard) manufactured by Amphenol ICC. This connector features a 90° right-angle orientation, through-hole solder termination, and unshielded design. The part is classified as obsolete, which necessitates identification of equivalent substitute components for ongoing procurement and system maintenance. The RJSNE508508 remains available in inventory (1114 pcs) but active alternatives should be evaluated for new designs and replenishment strategies.

• Orientation: 90° Angle (Right)
• Mounting Type: Through Hole
• Termination: Solder
• Shielding: Unshielded
• Contact Material: Phosphor Bronze
• Contact Finish: Gold (50.0µin / 1.27µm)
• Housing Material: Thermoplastic
• LED Color: Green - Green
• Tab Direction: Up and Down
• RoHS Compliance: Yes

Allowable Variation Parameters:

• Operating Temperature Range: Substitute may extend the range (lower minimum or higher maximum acceptable)
• Product Status: Substitute may be Active (preferred) or Obsolete
• Packaging: May differ (Tray vs. other formats)
• Inventory Status: Independent of substitution validity

The RJSAE508508 meets all mandatory matching criteria and qualifies as a direct substitute for the RJSNE508508.

Engineering Selection Recommendations

RJSAE508508 as Primary Substitute:

The RJSAE508508 is a direct functional and mechanical equivalent to the RJSNE508508. Selection of the RJSAE508508 is supported by the following engineering factors:

1. Product Status: The RJSAE508508 is classified as Active, ensuring continued manufacturer support, availability, and compliance updates. The RJSNE508508 is Obsolete, indicating discontinued production and potential supply constraints.

2. Electrical and Mechanical Equivalence: All critical parameters match exactly, including connector type, contact configuration, orientation, termination method, contact materials, and finish specifications. The connectors are functionally interchangeable in circuit applications.

3. Temperature Performance: The RJSAE508508 extends the operating temperature range to -55°C ~ 85°C, providing enhanced performance in low-temperature environments compared to the RJSNE508508 (-40°C ~ 85°C). This represents an improvement with no degradation in upper temperature limits.

4. Compliance Certification: Both parts maintain RoHS compliance and identical Moisture Sensitivity Level (MSL 1), ensuring regulatory and environmental compatibility.

5. Additional Feature: The RJSAE508508 includes Board Lock functionality, which provides enhanced mechanical retention on printed circuit boards compared to the base RJSNE508508 design.

Procurement Strategy:

For new designs and component replenishment, the RJSAE508508 should be specified. Existing inventory of RJSNE508508 may be utilized for legacy system maintenance where supply is available.

Frequently Asked Questions (FAQ)

Q1: Can the RJSAE508508 be used as a direct replacement for the RJSNE508508 in existing circuit designs?

A: Yes. The RJSAE508508 is a direct substitute. All electrical and mechanical parameters are identical, including connector type (Jack, 8P8C RJ45), orientation (90° right-angle), termination method (solder), contact materials (phosphor bronze with gold finish), and housing specifications. The connectors are pin-compatible and functionally equivalent.

Q2: What is the difference between the RJSNE508508 and RJSAE508508?

A: The primary differences are: (1) Product Status—RJSAE508508 is Active while RJSNE508508 is Obsolete; (2) Operating Temperature Range—RJSAE508508 extends to -55°C minimum versus -40°C for RJSNE508508; (3) Additional Feature—RJSAE508508 includes Board Lock functionality; (4) Packaging—RJSAE508508 is specified as Tray packaging. All other specifications are identical.

Q3: Does the Board Lock feature on the RJSAE508508 affect compatibility with the RJSNE508508?

A: No. The Board Lock feature is an enhancement that provides additional mechanical retention on the printed circuit board. It does not affect electrical performance or mechanical fit with mating connectors. The connector remains fully compatible with standard RJ45 plugs and existing circuit board layouts.

Q4: Are there any temperature-related limitations when substituting the RJSAE508508 for the RJSNE508508?

A: No. The RJSAE508508 has an extended operating temperature range (-55°C ~ 85°C) compared to the RJSNE508508 (-40°C ~ 85°C). This means the substitute performs across a wider temperature envelope and is suitable for all applications where the original part was used.

Q5: Is the RJSAE508508 RoHS compliant?

A: Yes. The RJSAE508508 is RoHS compliant, matching the compliance status of the RJSNE508508. Both parts meet environmental and regulatory requirements for restricted substance use.

Q6: What is the Moisture Sensitivity Level (MSL) for the RJSAE508508?

A: The RJSAE508508 has MSL 1 (Unlimited), identical to the RJSNE508508. This indicates no moisture sensitivity restrictions and unlimited shelf life under standard storage conditions.

Q7: Does packaging format affect the substitution decision?

A: Packaging format (Tray for RJSAE508508 versus unspecified for RJSNE508508) does not affect electrical or mechanical compatibility. Packaging selection is determined by procurement, handling, and inventory management requirements rather than functional performance.

Q8: Can the RJSAE508508 be used in high-reliability or military applications?

A: Substitution decisions for high-reliability or military applications must be based on specific application requirements and qualification standards beyond the parameters provided in this reference. Consult application-specific engineering documentation and manufacturer datasheets for such applications.
