Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RJSNEJ38LA8 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Jack
• Number of Positions/Contacts: 8p8c (RJ45, Ethernet)
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination: Solder
• Shielding: Shielded, EMI Finger
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Housing Material: Thermoplastic
• RoHS Status: RoHS Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The RJSAE538H08 meets all mandatory matching parameters and qualifies as a direct substitute. Both connectors share identical functional specifications for 8p8c modular jack applications with right-angle through-hole solder termination and shielded EMI protection.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538H08 is a qualified substitute for the obsolete RJSNEJ38LA8 based on the following engineering criteria:

Functional Equivalence: Both connectors are 8p8c (RJ45, Ethernet) modular jack connectors with identical mechanical and electrical interface specifications. The right-angle through-hole solder termination, shielded EMI finger design, and phosphor bronze gold-plated contacts ensure functional compatibility in existing circuit board layouts.

Compliance Alignment: Both parts maintain RoHS compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with current manufacturing and storage requirements.

Product Status Advantage: The RJSAE538H08 is classified as Active, providing assured long-term availability and supply chain stability compared to the obsolete RJSNEJ38LA8.

Operating Temperature Consideration: The RJSAE538H08 supports an extended lower operating temperature range (-55°C vs. -40°C), providing broader environmental compatibility without compromising upper temperature performance.

Contact Finish Thickness: The RJSAE538H08 features increased gold plating thickness (50.0µin vs. 30.0µin), which may provide enhanced durability and contact reliability in high-cycle insertion applications.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE538H08 be used as a direct replacement for the RJSNEJ38LA8 in existing designs?

A: Yes. Both connectors share identical specifications for connector type, contact count, mounting method, orientation, termination, shielding, contact material, and housing material. The RJSAE538H08 is functionally equivalent and mechanically compatible with circuit board layouts designed for the RJSNEJ38LA8.

Q: What is the difference in contact finish thickness between these two connectors?

A: The RJSNEJ38LA8 has a gold contact finish thickness of 30.0µin (0.76µm), while the RJSAE538H08 has 50.0µin (1.27µm). The thicker plating on the RJSAE538H08 may provide improved contact durability and wear resistance in applications with frequent mating cycles.

Q: Are there any temperature range limitations when substituting the RJSAE538H08 for the RJSNEJ38LA8?

A: No. The RJSAE538H08 supports an operating temperature range of -55°C to 85°C, which encompasses the -40°C to 85°C range of the RJSNEJ38LA8. The extended lower temperature capability of the substitute part does not create any compatibility constraints.

Q: Do both connectors meet the same regulatory and compliance standards?

A: Yes. Both the RJSNEJ38LA8 and RJSAE538H08 are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. Both are classified under ECCN EAR99 and HTSUS 8536.69.4040, ensuring equivalent regulatory compliance.

Q: What is the primary advantage of selecting the RJSAE538H08 over the RJSNEJ38LA8?

A: The RJSAE538H08 is classified as Active product status, ensuring continued availability and supply chain support. The RJSNEJ38LA8 is obsolete, making the RJSAE538H08 the recommended choice for new designs and ongoing production requirements.

Q: Are the LED color indicators the same on both connectors?

A: No. The RJSNEJ38LA8 features Green and Yellow-Red LED colors, while the RJSAE538H08 features Green and Yellow-Green LED colors. LED color selection should be verified against specific application requirements if indicator color is a design specification.
