Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RJSNEJ38A08 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Jack
• Contact Configuration: 8p8c (RJ45, Ethernet)
• Orientation: 90° Angle (Right)
• Mounting Type: Through Hole
• Termination Method: Solder
• Shielding: Shielded, EMI Finger
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Housing Material: Thermoplastic
• RoHS Compliance: Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The RJSAEJ38A08 meets all mandatory matching parameters and qualifies as a direct substitute. Both connectors share identical mechanical and electrical specifications for the contact system, shielding configuration, and termination interface. The primary distinction is product status: RJSNEJ38A08 is obsolete while RJSAEJ38A08 is active.

Parameter Comparison

Engineering Selection Recommendations

The RJSAEJ38A08 is a qualified substitute for the obsolete RJSNEJ38A08 based on complete parameter equivalence across all critical mechanical and electrical specifications. Both connectors are manufactured by Amphenol ICC (Commercial Products) and maintain identical contact configurations, shielding characteristics, and termination methods.

The RJSAEJ38A08 offers an extended operating temperature range (-55°C ~ 85°C versus -40°C ~ 85°C), providing additional thermal margin for applications operating at lower ambient temperatures. Both parts maintain RoHS compliance and identical moisture sensitivity ratings.

The active product status of RJSAEJ38A08 ensures ongoing availability and supply chain support, addressing the obsolescence of the original RJSNEJ38A08. Selection of the substitute part requires no design modifications to PCB layouts, connector footprints, or mating interface specifications.

Frequently Asked Questions (FAQ)

Q: Can RJSAEJ38A08 be used as a direct replacement for RJSNEJ38A08 without PCB modifications?

A: Yes. Both connectors share identical mechanical dimensions, through-hole footprints, and solder termination specifications. No PCB layout changes are required.

Q: What is the difference in operating temperature range between these connectors?

A: RJSNEJ38A08 operates from -40°C to 85°C. RJSAEJ38A08 operates from -55°C to 85°C. The substitute part supports lower temperature operation, making it suitable for a broader range of environmental conditions.

Q: Are both connectors RoHS compliant?

A: Yes. Both RJSNEJ38A08 and RJSAEJ38A08 are RoHS compliant with identical moisture sensitivity levels (MSL 1, Unlimited).

Q: Why is RJSNEJ38A08 listed as obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. The RJSAEJ38A08 represents the active equivalent in Amphenol ICC's current product portfolio.
