Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the RJSNEJ388A8 is based on electrical and mechanical compatibility across the following critical parameters:

• Connector Type & Contact Count: Jack, 8p8c (RJ45, Ethernet)
• Physical Configuration: 90° right-angle orientation, through-hole mounting, solder termination
• Shielding & EMI Performance: Shielded design with EMI finger for electromagnetic interference mitigation
• Contact Specifications: Phosphor bronze material with gold finish (30.0µin thickness)
• Housing & Tab Design: Thermoplastic housing with up and down tab direction
• Environmental & Compliance: RoHS compliance and MSL 1 rating for unlimited moisture exposure

The RJSAEJ38808 qualifies as a direct substitute because it maintains identical specifications across all critical parameters: connector type, contact configuration, mounting method, orientation, termination type, shielding approach, contact materials and finish, housing material, and tab direction. Both components share the same operating temperature range lower bound and identical environmental/compliance ratings.

Parameter Comparison

*The RJSAEJ38808 supports an extended lower operating temperature range (-55°C vs. -40°C), making it compatible with the RJSNEJ388A8 specification and applicable to wider temperature environments.

Engineering Selection Recommendations

Both parts maintain RoHS compliance and MSL 1 rating, confirming equivalent environmental and regulatory suitability.

Current inventory availability of 1083 units for the RJSAEJ38808 supports immediate procurement without design modification or board redesign.

Frequently Asked Questions (FAQ)

Q: Can RJSAEJ38808 be used directly in place of RJSNEJ388A8 without PCB modification?

A: Yes. The RJSAEJ38808 maintains identical mechanical footprint, mounting type (through-hole), orientation (90° right-angle), and termination method (solder). No PCB redesign is required.

Q: What is the primary difference between these two parts?

A: The RJSNEJ388A8 is Obsolete, while the RJSAEJ38808 has Active product status. The RJSAEJ38808 also supports an extended lower operating temperature range (-55°C minimum versus -40°C), providing enhanced cold-temperature performance.

Q: Are the shielding and EMI characteristics identical?

A: Yes. Both parts feature shielded design with EMI finger, phosphor bronze contacts with gold finish (30.0µin thickness), and identical housing materials and tab direction. EMI and signal integrity performance are equivalent.

Q: Is RoHS compliance maintained in the substitute?

A: Yes. The RJSAEJ38808 is RoHS Compliant with identical Moisture Sensitivity Level (MSL 1), ensuring equivalent environmental and regulatory compliance.

Q: Are there any electrical or contact performance differences?

A: No. Both parts utilize phosphor bronze contacts with gold finish plating at 30.0µin thickness and function as 8p8c (RJ45, Ethernet) jack connectors with identical contact configuration and termination specifications.
