Key Parameters

Substitute Part Grouping Explanation

The RJSAE538708 qualifies as a direct substitute based on matching critical parameters that define functional equivalence for modular jack connectors. The substitution criteria are as follows:

Critical Matching Parameters:

• Connector type (Jack)
• Contact configuration (8p8c/RJ45)
• Mounting method (Through Hole)
• Mechanical orientation (90° right-angle)
• Termination type (Solder)
• Shielding architecture (Shielded with EMI finger)
• Housing material (Thermoplastic)
• Environmental compliance (RoHS Compliant)
• Moisture sensitivity classification (MSL 1)

Variable Parameters Within Acceptable Range:

• Contact finish thickness: 15.0µin (0.38µm) to 50.0µin (1.27µm)
• Operating temperature lower limit: -40°C to -55°C

These variations remain within acceptable tolerances for electronic assembly applications and do not compromise electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538708 is the appropriate substitute for the obsolete RJSNEG38708. Both parts are manufactured by Amphenol ICC and maintain RoHS compliance and EAR99 export classification. The RJSAE538708 benefits from active product status, ensuring ongoing availability and supply chain reliability.

The thicker gold contact finish on the RJSAE538708 (50.0µin vs. 15.0µin) provides enhanced durability characteristics. The extended low-temperature operating range of the RJSAE538708 (-55°C vs. -40°C) offers broader environmental compatibility, making it suitable for applications with more demanding thermal requirements.

Selection of the RJSAE538708 eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with the original connector specification.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable?

A: Yes. Both parts utilize the same 8p8c (RJ45) contact configuration, phosphor bronze contact material with gold finish, and identical termination method (solder). Electrical performance characteristics remain equivalent for standard Ethernet and modular jack applications.

Q: Does the difference in contact finish thickness affect compatibility?

A: No. The contact finish thickness variations (15.0µin versus 50.0µin) remain within standard tolerances for RJ45 connectors and do not impact mechanical insertion or electrical contact resistance. The thicker finish on the RJSAE538708 extends wear tolerance for repeated mating cycles.

Q: Can the RJSAE538708 replace the RJSNEG38708 in existing designs?

A: Yes. The parts share identical mounting footprints, orientations (90° right-angle), and through-hole termination specifications. No PCB layout modifications are required.

Q: Why is the RJSNEG38708 marked obsolete?

A: The RJSNEG38708 has been superseded by the RJSAE538708 in the Amphenol ICC product line. The RJSAE538708 provides the same functionality with broader environmental specifications and enhanced contact durability.

Q: Are there any certification or compliance differences?

A: Both parts carry RoHS compliance and EAR99 export classification. Moisture sensitivity levels (MSL 1) and HTSUS codes are identical, ensuring equivalent handling and regulatory treatment throughout the supply chain.

Q: Can these parts be used in new designs?

A: The RJSAE538708 is the appropriate choice for new designs. The RJSNEG38708 should not be specified for new development due to obsolete status.
