Parameter Comparison

Engineering Selection Recommendations

The RJSAE538B08 is the qualified substitute for the obsolete RJSNEJ38C08. Both components are manufactured by Amphenol ICC (Commercial Products) and maintain full RoHS compliance with MSL 1 rating. The substitute part offers the following advantages:

Active Product Status: The RJSAE538B08 is classified as an active product, ensuring ongoing manufacturing support, availability, and supply chain continuity.

Enhanced Contact Durability: The RJSAE538B08 features increased gold contact finish thickness (50.0µin versus 30.0µin), providing improved wear resistance and contact reliability over extended operational cycles.

Extended Temperature Range: The RJSAE538B08 supports operation from -55°C to 85°C, compared to -40°C to 85°C for the original part, offering broader environmental compatibility.

Electrical and Mechanical Equivalence: All critical functional parameters remain identical, including connector configuration, shielding, termination method, and board lock features, ensuring direct functional replacement without design modification.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE538B08 be used as a direct replacement for the RJSNEJ38C08 without PCB redesign?

A: Yes. Both connectors share identical mounting type (through hole), orientation (90° right-angle), contact configuration (8p8c RJ45), and termination method (solder). No PCB layout modifications are required.

Q: What is the significance of the contact finish thickness difference?

A: The RJSAE538B08 provides 50.0µin (1.27µm) gold plating compared to 30.0µin (0.76µm) on the RJSNEJ38C08. Increased plating thickness enhances contact durability and extends service life under repeated mating cycles.

Q: Does the extended operating temperature range of the RJSAE538B08 affect compatibility?

A: No. The RJSAE538B08 supports -55°C to 85°C operation, which encompasses the original -40°C to 85°C range. This represents an expansion of environmental capability with no compatibility restrictions.

Q: Are both parts RoHS compliant?

A: Yes. Both the RJSNEJ38C08 and RJSAE538B08 are RoHS compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the difference in LED color options between the two parts?

A: The RJSNEJ38C08 offers Red, Green and Green, Yellow LED options, while the RJSAE538B08 provides Red, Green and Red, Green options. LED color selection should be verified against specific application requirements.

Q: Is the RJSAE538B08 available in the same packaging format?

A: The RJSAE538B08 is supplied in tray packaging, whereas the RJSNEJ38C08 packaging specification was not provided. Packaging format should be confirmed with procurement requirements for your application.
