Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RJSNEJ38MA8 is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Jack, 8p8c (RJ45, Ethernet)
• Orientation & Mounting: 90° right-angle, through-hole solder termination
• Shielding Architecture: Shielded with EMI finger
• Contact System: Phosphor bronze with gold finish
• Housing Material: Thermoplastic
• Compliance: RoHS compliant, MSL 1

The substitute part RJSAE538708 meets all these criteria, with documented differences limited to contact finish thickness, operating temperature range extension, LED color variation, and product status transition from Obsolete to Active.

Parameter Comparison

Engineering Selection Recommendations

The RJSNEJ38MA8 is classified as Obsolete. The substitute part RJSAE538708 is the equivalent component currently in active production status from Amphenol ICC (Commercial Products).

Selection Basis:

Both parts maintain identical electrical and mechanical specifications across all critical connector parameters: 8p8c RJ45 configuration, 90° right-angle through-hole solder termination, shielded EMI finger design, phosphor bronze gold-plated contacts, and thermoplastic housing.

The RJSAE538708 provides two technical enhancements over the original specification:

1. Contact Finish Thickness: Increased from 30.0µin to 50.0µin, providing enhanced durability and contact reliability
2. Operating Temperature Range: Extended lower operating limit from -40°C to -55°C, expanding environmental capability

Both components are RoHS compliant with MSL 1 rating and identical ECCN/HTSUS classifications. The transition from Obsolete to Active status ensures continued availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can RJSAE538708 directly replace RJSNEJ38MA8 in existing designs?

A: Yes. Both connectors are functionally equivalent across all critical parameters: connector type, configuration, orientation, mounting method, termination, shielding, contact materials, and housing. Electrical and mechanical compatibility is maintained.

Q: What are the differences between these two parts?

A: The primary differences are: (1) Contact finish thickness—RJSAE538708 provides 50.0µin versus 30.0µin on the original; (2) Operating temperature range—RJSAE538708 extends to -55°C minimum versus -40°C; (3) LED color—Red-Yellow on RJSNEJ38MA8 versus Red-Green on RJSAE538708; (4) Product status—RJSAE538708 is Active while RJSNEJ38MA8 is Obsolete.

Q: Are there packaging differences?

A: Yes. RJSNEJ38MA8 packaging is not specified in available documentation. RJSAE538708 is supplied in Tray packaging. Confirm packaging requirements for your application.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both RJSNEJ38MA8 and RJSAE538708 are RoHS compliant with identical MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Which part should be selected for new designs?

A: RJSAE538708 is the recommended selection for new designs due to Active product status, enhanced contact finish thickness, and extended operating temperature range.

Q: Are the board lock and LED features identical?

A: Both parts include board lock functionality. LED color differs: RJSNEJ38MA8 features Red-Yellow; RJSAE538708 features Red-Green. Confirm LED color requirements for your application.
