RJSNE5F8BA8 Equivalent & Substitute Parts

Part Overview

The RJSNE5F8BA8 is a shielded modular jack connector (RJ45/Ethernet) with 8 positions and 8 contacts (8p8c), configured for 90° right-angle mounting through through-hole termination. Manufactured by Amphenol ICC, this connector incorporates phosphor bronze contacts with gold plating and a thermoplastic housing rated for -40°C to 85°C operation. The product status is obsolete, necessitating identification of compatible substitute connectors that maintain electrical and mechanical compatibility with existing circuit board designs and mating plugs.

Substitute Part Grouping Explanation

The RJSNE5F8BA8 can be substituted with the RJSAE538B08 based on strict parameter equivalence. The substitution is valid because both connectors share the following critical electrical and mechanical compatibility parameters:

• Identical connector type: modular jack (8p8c/RJ45)
• Identical number of positions and contacts: 8p8c
• Identical orientation: 90° right-angle configuration
• Identical mounting type: through-hole
• Identical termination method: solder
• Identical shielding classification: shielded
• Identical contact material: phosphor bronze
• Identical contact finish and thickness: gold (50.0µin / 1.27µm)
• Identical housing material: thermoplastic
• Identical tab direction: up and down
• Identical LED indicator colors: red and green
• Identical board lock feature
• Identical RoHS compliance status
• Identical MSL rating: 1 (unlimited)

The primary technical differences between the main part and substitute are limited to product status (obsolete versus active), operating temperature range (−40°C ~ 85°C versus −55°C ~ 85°C), and the addition of an EMI finger feature on the substitute. These differences do not prevent functional substitution in applications designed for the original connector specifications.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538B08 is suitable as a direct substitute for the obsolete RJSNE5F8BA8 in applications requiring 8p8c modular jack connectors with 90° right-angle through-hole mounting and solder termination. Both connectors maintain RoHS compliance and identical MSL ratings, ensuring regulatory and environmental compatibility across both new production and replacement scenarios.

The RJSAE538B08 offers an extended lower operating temperature limit of −55°C compared to the −40°C minimum of the original part, providing enhanced performance in low-temperature environments. The addition of an EMI finger feature on the substitute connector provides supplementary electromagnetic interference protection while maintaining full mechanical and electrical compatibility.

The active product status of the RJSAE538B08 ensures continued availability and supply chain stability, eliminating procurement challenges associated with the obsolete RJSNE5F8BA8.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE538B08 directly replace the RJSNE5F8BA8 in existing designs?

A: Yes. Both connectors share identical specifications for all critical electrical and mechanical parameters: 8p8c contact configuration, 90° right-angle orientation, through-hole mounting, solder termination, shielded design, gold-plated phosphor bronze contacts, and thermoplastic housing. Pin pitch and mating interface are identical, enabling direct board-level substitution.

Q: What is the difference between the shielding in the two connectors?

A: The RJSNE5F8BA8 provides shielded construction, while the RJSAE538B08 incorporates shielded construction with an additional EMI finger. The EMI finger enhances electromagnetic interference suppression while maintaining mechanical compatibility and not altering the mating interface.

Q: How do the operating temperature ranges differ?

A: The RJSNE5F8BA8 operates from −40°C to 85°C, while the RJSAE538B08 operates from −55°C to 85°C. For applications operating below −40°C, the RJSAE538B08 provides improved performance specifications.

Q: Are there packaging differences between these connectors?

A: The RJSNE5F8BA8 packaging specification is not provided. The RJSAE538B08 is supplied in tray packaging. Confirm packaging requirements against your procurement and assembly specifications.

Q: Do both connectors maintain the same regulatory compliance?

A: Yes. Both the RJSNE5F8BA8 and RJSAE538B08 are RoHS compliant and classified under identical ECCN (EAR99) and HTSUS (8536.69.4040) codes, ensuring equivalent regulatory status for export and environmental compliance.

Q: What is the MSL rating for these connectors?

A: Both connectors carry an MSL rating of 1 (Unlimited), indicating minimal moisture sensitivity. Standard warehouse storage and handling procedures are sufficient; special dry-pack or bake-out procedures are not required.
