Parameter Comparison

Engineering Selection Recommendations

The RJSAE538708 is the direct substitute for the obsolete RJSNEJF87A8 based on product status and compliance alignment. Both components are RoHS compliant and carry identical ECCN and HTSUS classifications, confirming regulatory equivalence.

Advantages of RJSAE538708:

• Active product status ensures long-term availability and manufacturing continuity
• Enhanced EMI finger shielding provides additional electromagnetic interference protection
• Extended operating temperature range (-55°C ~ 85°C) accommodates broader environmental conditions
• Increased contact finish thickness (50.0µin vs. 30.0µin) improves contact durability and wear resistance

Compatibility Confirmation: The substitute maintains identical electrical and mechanical interfaces, including 8P8C contact configuration, 90° right-angle orientation, through-hole solder termination, and board lock mechanism. Footprint and pin assignment are equivalent, enabling direct replacement in existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can RJSAE538708 directly replace RJSNEJF87A8 on existing PCBs?

A: Yes. Both connectors share identical mounting type (through hole), orientation (90° right-angle), contact configuration (8P8C RJ45), and termination method (solder). PCB footprints are compatible without modification.

Q: What is the significance of the EMI finger in RJSAE538708?

A: The EMI finger provides enhanced electromagnetic interference shielding. This is an additional feature that does not affect mechanical or electrical compatibility; it improves signal integrity in high-noise environments.

Q: Why does RJSAE538708 have a thicker gold contact finish?

A: The increased contact finish thickness (50.0µin vs. 30.0µin) extends contact life and improves resistance to wear and corrosion. This represents an engineering enhancement without affecting substitution compatibility.

Q: What is the temperature range difference between the two parts?

A: RJSNEJF87A8 operates from -40°C to 85°C, while RJSAE538708 operates from -55°C to 85°C. The substitute supports a wider low-temperature range, making it suitable for applications requiring extended cold-temperature performance.

Q: Are both parts RoHS compliant?

A: Yes. Both RJSNEJF87A8 and RJSAE538708 are RoHS compliant with MSL rating 1 (unlimited moisture sensitivity level).

Q: What packaging is available for RJSAE538708?

A: RJSAE538708 is supplied in tray packaging, suitable for automated assembly and high-volume production environments.

Q: Why is RJSNEJF87A8 classified as obsolete?

A: Obsolescence indicates the part is no longer in active production. RJSAE538708 is the active equivalent, ensuring continued supply and manufacturing support for new designs and field replacements.
